The satellite, generally referred to as PACSAT, has been dreamed about for nearly half a decade since the conception of the TAPR TNC. There are several "fertile" launch opportunities within calendar 1988 and 1989 and the AMSAT Board has authorized the formation of a PACSAT team and funded it at $50,000 to take advantage of any feasible launch that would be compatible with the PACSAT mission. According to Tom Clark, W3IWI, a major portion of the design of PACSAT is complete, and the construction of a prototype will commence immediately. All packet-radio enthusiasts will be able to make use of the PACSAT satellite when it is launched, possibly within the next two years. Attainment of this very ambitious goal will entail financial support and a special fund has been set up for this purpose. Contact AMSAT, PO Box 27, Washington, DC 20044 for further details. >from The ARRL Letter PHASE 3C UNDERGOES PRE-LAUNCH TESTS AMSAT's new Phase 3 satellite is undergoing pre-launch tests at AMSAT-DL in West Germany. If all goes well, this new OSCAR will be launched on the European Space Agency's (ESA) V-22 mission planned for March 15, 1988. Like OSCAR-10, this new satellite will also be placed in a highly elliptical orbit. It is expected to carry three linear transponders and a single- frequency, digital RUDAK transponder. Satellite operations should include: Mode B : 435 MHz up, 145 MHz down. Mode JL : 1269 MHz, 145 MHz up, combined 435 MHz down. Mode S : 435 MHz up, 2400 MHz down. RUDAK : 1269.675 MHz up, 435.675 MHz down. >from Space News THIRD REGION ADOPTS 5-DIGIT ZIP CODE ROUTING The Third Region has recently adopted 5-digit ZIP codes for NTS traffic forwarding. The format is used without any @<bbs_call> or @<section_designator> entries. The @<anything> may still be used for those entries that require it, but the 5-digit routing is preferred. In addition, the Title entry serves a new purpose. Recognizing that NTS ultimately operates to serve the user, the Title entry will be of the form: <town_name> / <phone_exchange> that is, the town and telephone exchange of the addressee, not the originating station. This will allow a local user to use the LT (list traffic) command and determine immediately whether or not it is a deliverable message without actually reading the message to see where it is going. The PBBS would respond to the LT command, as follows: 14707 TN 236 18013 WA3PGR 25-NOV EAST BANGOR / 588 14705 TN 566 18042 KR0AK 25-NOV EASTON / 250 14703 TN 502 18103 WA3PGR 25-NOV ALLENTOWN / 820 The user can quickly identify and download those messages which he is capable of handling. It is hoped that this will increase efficiency and cut down on unnecessary downloads. Black Box Theory Within the Third Region, T traffic is defined as that sent using the ST command; traffic that is killable (via the K command) by anyone and generally destined for a third party, not necessarily a ham and not necessarily NTS (but certainly driven by NTS). Let's "construct" the Third Region as a multiported black box. The entry portals, for the purpose of this example are two HF portals, AG3F and W3IWI, and four VHF/UHF portals, W2XO, K3RLI, AK3P and KB3UD. (Before PBBSs get excited, remember that this is only an example). @AG3F @K3RLI | | ---------------------------------------- @ | 16*-> <-15* 17?-> <-15* | K @W2XO-| 17*-> 18*-> <-16* 18* |-B | 18*-> 19*-> <-17? 19* | 3 | 19*-> 17* v | U | <-15* 18*-> | D |15* <-16* 19*-> ^ 2* | ----------------------------- | | | | | 1* v | * = ALL @AK3P ----------- ? = "SOME" @W3IWI Any of these portals are equipped to receive T traffic addressed either TO ZZZZZ or TO ZZZZZ @NTSst (NTSst is either NTSPA, NTSDE, NTSMD or NTSMDC) where TO ZZZZZ using the 5-digit ZIP code is preferred. Using wild-card forwarding, each of these portals has the ability to send the received T traffic in its appropriate direction with minimal forwarding file entries. 15*s and 16*s go west, some 17*s go central, some 17*s and 18*s go north by northeast, some 18*s go east and 19*s go southeast. If T traffic is received with an @<entry> in the NTS<state> format, then this would be stripped and replaced by a null to permit full-featured 5-digit ZIP routing to take effect. This also allows alternate routing in the case of path failures or simply for redundancy. There is also the outward flow in which case 4*s go west to Ohio, 5*s, 6*s, 7*s, 8*s and 9*s all head in the direction of the closest HF portal; 0*s go northeast, 1*s need to be defined one layer deeper to the next ZIP digit before they reach a portal, but can be easily wild-carded as well. A similar black box can be constructed for every state and the routing of T traffic can assume an orderly march to its destination based upon its 5-digit ZIP code address. >from Tom Teel, KB3UD (@ KB3UD), 3rd Region Packet Manager and STM of Eastern Pennsylvania XEROX 820 W0RLI PBBS SOFTWARE UPDATED A new version of the W0RLI PBBS software for the Xerox 820 computer has been produced by John Bennett, N4XI. The following changes and additions are included: o Fixed the bug which did not allow messages numbered higher than 9999 from being displayed. o Fixed the bug which allowed garbage to be sent to the TNC when the message count is 0 and you issue a "bt $E." o Fixed the bug in SYSGEN which prevented bootstrap tracks from being written on a 5.25-inch disk drive systems. o Added forwarding capability through NET/ROM and COSI network nodes. Connect (success) messages and prompts from nodes are configurable in CONFIG.TNC file. o Added deletion of the @ field in received message on conditional match with list given in CONFIG.TNC file. o Added a second forwarding file to permit forwarding the same file at two different times or two files at their own time. o Added message text in the CONFIG.TNC file to be sent to a user when he invokes the KT command and no service message is generated. o Added MAXERR count to the CONFIG.TNC file to set the number of bad commands before a forced log-off occurs (may be changed from the local menu using the P command). o Added flag in the CONFIG.TNC file to selectively and automatically kill private messages (P messages). o Added flag in the CONFIG.TNC file to selectively and automatically kill NTS type messages (T and S messages). o Added a software clock set from a hardware clock for automatic booting (this is operable only when an additional circuit is installed). o Added hard disk modifications for CBIOS integrated into CBIOS. o Added Xerox 820-II modifications in CBIOS to permit use of the LP keyboard and the terminal bell. o Provided utility programs to transfer COM and data files between two Xerox computers via their serial ports (e.g., transfer between 8-inch and 5.25-inch disk drive systems). A copy of the software may be obtained by sending two 8-inch, single-sided disks and a self-addressed disk mailer with sufficient postage to John Bennett, N4XI, 5805 Whitehorne Dr, Evansville, IN 47710. Note that double-sided disks cannot be copied. Also, if you only need the source code and do not plan to run a hard disk, then one disk will suffice. >from John Bennett, N4XI WORLDWIDE PBBS LIST AVAILABLE Dave Zeph, W9ZRX, is the keeper of the worldwide PBBS list and the latest edition of the list is now available for downloading from CompuServe's HamNet or directly from Dave by sending a formatted 5.25-inch diskette (for an IBM PC/XT/AT or compatible computer) with a diskette mailer, address label and return postage to Dave at 16310 Spring Mill Road, Westfield, IN 46074. The current list contains approximately 700 systems located in the United States, Canada and overseas. In the past, the list has been published in Gateway, but due to its size, this is no longer possible as it would fill two complete issues of the newsletter! The list is only as good as the information received, so Dave eagerly solicits additions, corrections, modifications and suggestions. If you have something to send, Dave needs the following data: PBBS call sign, PBBS name, PBBS address (city, state, ZIP code, grid square, latitude and longitude, telephone area code), port frequency(ies), which ports are open and which ports are closed and the call sign of the nearest HF gateway. As the keeper of the PBBS list, Dave made the following observations: Packet networking is spreading around the globe; an ASIANET forwarding network has been established on 14.111 MHz. The list includes the first PBBSs in India and Africa (Kenya). Now, there are PBBSs in 48 states (Delaware and Nevada are still missing) with 549 US. PBBSs in all. The most explosive growth in the last four months has been in Montana, which now boasts five systems. Oregon remains the "black hole" of PBBSs with the fewest (only two) for a "major" state. The greatest unknown in packet forwarding today: Is there a path to Idaho? >from Dave Zeph, W9ZRX NOVICE NOTCH Southern California In Southern California, there is a packet-radio network on the 220-MHz band that serves two purposes: 1) access to WESTNET for Novice (and other) users via 223.42 MHz and 2) as a backup forwarding channel for several PBBS stations in the area. Because of the user-oriented status of the channel, the second function is generally limited to off-hours. The facilities on the channel are, as follows: PBBS Stations Location AJ6F-11 Torrance (LAX/NTS) K6IYK-14 Chatsworth (S CA VHF Gateway) KB6GVT-1 Rialto (IEBBS support) KD4SQ-2 Riverside (BBS access only) Digipeaters Location KB6CUN Hollywood Hills KD6SQ-4 Riverside (144.76 MHz gateway) N6PWD Huntington Beach NET/ROM Nodes Location K6IYK-13/VERA13 Hollywood Hills W6TJ-2/SBD1 San Bernardino Mountains W6VPZ-11/PV11 Palos Verdes All of the listed PBBS stations have multiport capabilities and support at least one other port on 2 meters. AJ6F-11 is accessible on 145.07 MHz (users) and, as AJ6F-1, on 145.36 MHz (PBBS). K6IYK-14 is available on 145.01 MHz (users) and, as K6IYK-4, on 145.36 MHz (PBBS). K6IYK also supports traffic to and from WESTNET on a 220-MHz backbone frequency. KB6GVT-1 is also available on 145.03 MHz. KD6SQ-2 has additional ports on 2 and 40 meters, but access is limited to other PBBS stations. Novice users are encouraged to acquaint themselves with the 220-MHz activity. The facilities are abundant; why not use them! >from Bob Poole, AJ6F Northern New Jersey The Major Armstrong Memorial Amateur Radio Club, Inc. has a NET/ROM node on 223.420 MHz located in Alpine, New Jersey (on the cliffs of the Hudson River, across the river from Yonkers, New York). A PBBS (W2LWB-4) is available there also. >from John Gubernard, K2LSX (Gateway would like to continue to publicize Novice packet activities, so if you know of any, please let me know, too. - WA1LOU) CONNECT INTERNATIONAL QRX We have word that RSGB's Connect International monthly packet newsletter has suspended publication, as they are in between editors.

A NOTE ABOUT CONTACTING A DIGITAL DXPEDITION After being on a number of digital DXpeditions, we find it necessary to provide some brief notes on how to make a contact with us or other digital DXpedition. Remember that, in most cases, we are battery and/or gasoline powered and that our operating time is limited. We have portable equipment and portable antennas and may be plagued by poor ground and by RF getting into the equipment on certain frequencies. Under these conditions, we are trying to contact as many stations as possible (because there is little activity from the spot we are visiting). Often we are the only station active in a particular digital mode (packet radio, RTTY, ASCII and AMTOR) >from that DXCC country. With that understood, we would appreciate it if you followed these three simple recommendations: o Send short RY-trailers; we do not have time or need 80 RYs! o Send short calls (call only: RYRYRY LA4LN DE your call K). o Keep the QSO short; just RST three times; we will ask if we want more information. Many stations call at the same time, so we listen at least 1 kHz, often 5 kHz unless we make an announcement otherwise. We try to keep QSOs short, often limited to RST, so that we may work as many stations as possible during our limited time. Do not expect us to give our name, QTH and QSL information in every QSO. Listen a few minutes and we will give it periodically. Do not expect us to have time to listen to the complete history of your life. When operating from the wilderness of Iceland, we would like to spread our gasoline evenly among the many stations we contact. Finally, please do not call CQ or start a QSO close to our frequency. We use low power and need that frequency window. Thank you in advance; we hope to chat with you when we get back home. >from Siri, LA2SR, and Tom Victor Sega|stad, LA4LN, in SARTG News WAIT 'TIL NEXT YEAR Since Gateway is only published 25 times per year, twice a year there is a three week break between issues rather than the normal two week break.

Unlike BSD Unix, the telnet server in NET is strictly a keyboard-to-keyboard 'chat' process. Nothing exists yet to allow remote logins. If you'd like to try to make it work, let me know.

This is a feature, not a bug. :-) Every net.exe module is a IP packet switch as well as an end-user host, and every incoming and outgoing packet passes through the IP switch module. Packets sent to yourself never reach a hardware interface -- they are looped right back "upstairs" in software. > If I set 'trace ax0 110', > I decode frames properly - except that all TCP headers, and about 1/3 of the > IP headers, get 'CHECKSUM ERROR (n)'. There was a portability bug in the .0 version, I think; it has since been corrected. Look for the function eac() in iproute.c. Make sure that each constant of the form "0xffff" is specified as a LONG integer (i.e., 0xffffL). Some compilers were sign-extending this constant to 32 bits (i.e., 0xffffffff) which was not the intended effect. > 1) In the Unix attach asy command, what does the first parameter (the > address of the comm port, under MS-DOS) mean?

The bbs is PRMBS using COMBIOS which is pretty much the same as MBBIOS. Net has its own aync driver so it doesn't need mbbios. All net needs to know is the com port address and interrupt vector. It sounds like you are sharing interrupt vectors between devices by chaining onto the interrupt vector. I didn't do it this way because net currently doesn't share the vector but replaces it. A much easier way to run both on the same system is to put net on a com port with its own vector interrupt vector (the typical case) and use the shared vector ports for the bbs side of the system. On an XT I jumpered my com3 port to IRQ2 instead of 3 or 4. IRQ2 is not used on most XT systems. I can run net or the bbs with a modified mbbios/combios on this port. I have passed this info to Phil and the next version of net will chain onto the vector if this will make running dual systems easier. Some of you may be wondering why net doesn't use mbbios/combios too. Net does its own internal multi-tasking which needs full interrupt driven IO for both transmit and receive. Combios/mbbios only uses interrupt driven receive and busy wait on transmit.

As it turns out, it wasn't keying the transceiver for telnetting anywhere else, either. This was a result of another portability bug in lcsum.c. The #ifdef that tries to determine if it's running on an Intel architecture wasn't detecting that Microport was an Intel OS, so it didn't set the LITTLE_ENDIAN flag.

Keywords: perennial checksum errors have gotten the Christmas version of the KA9Q TCP/IP code compiled under Microport System V/AT. Aside from a gotcha (a compiler error in slip.c), it compiled clean after I set up config.h. However, I'm running into another problem: My transmitter never keys if I try to telnet to myself. I have done route adds and arp adds for the appropriate pathing, but no soap. If I try to do an AX25 connect to myself, everything works fine. If I set 'trace ax0 110', I decode frames properly - except that all TCP headers, and about 1/3 of the IP headers, get 'CHECKSUM ERROR (n)'. Questions: 1) In the Unix attach asy command, what does the first parameter (the address of the comm port, under MS-DOS) mean? I looked at the asy_attach code in slip.c (coincidentally, where the compiler error manifested itself! It was a register assignment error, though, not a C error.), and it doesn't seem to use argv[1] at all in that routine. My attach command looks like: attach asy 55 /dev/tty1 ax25 ax0 2048 256 4800 Is this right? (assuming that the TNC is tied to /dev/tty1) 2) Am I correct in my assumption that, if I can do ax25 connects, that the rest of the prereqs (except for the code on the host itself) are OK as well? 3) What is the (n) in the CHECKSUM ERROR message? 4) Are there any other gotchas for running it under Unix?

Cheers to all, Dave, N6KL (n6kl@ibm.com or N6KL @ NV6Z) ........... Date: 7 January 88, 11:15:34 PST From: Roy Engehausen, AA4RE There is no reason why you cannot have any number of programs using the different COM ports on the multi-serial cards but the programs must use the "BIOS" interface thru INT14 to communicate with the port. It is my understanding that NET.EXE uses a direct hardware interface. I sure would like to see someone fixup NET.EXE so it could use INT14 for its port I/O since that would also enable you to use the PACCOMM PC-100 cards internal to the PC for NET.EXE.. The current version of MBBIOS has a KISS driver for the PC-100 cards included. MBBIOS has the capability for interrupt driven transmit. It is normally disabled since with the standard BBS programs, it seems to cause difficulty. It can be enabled easily with DEBUG for a certain port or using MBBCONFG for all ports. Chaining interrupt vectors will not work on the PC/XT/AT architecture. Because edge triggering is used, it is impossible for multiple interrupt handlers that have been chained together to ensure that all interrupts have been serviced. You must used a single handler that confirms that all devices are clear before leaving the handler. If you have any questions or want to correspond further, I can be found on COMPUSERV or directly to AA4RE @ AA4RE. I would be very happy to work with the NET.EXE people to enable them to use MBBIOS. Thanks to N6KL for bringing your USENET note to my attention and for sending this reply.

We felt that there was such a great body of proposed changes that a "fresh" look into the problem was required. Proposed changes could fall into three basic groups: format, operational parameters and elements of procedure. We felt that by addressing the format related issues we could provide a framework for reasonable and manageable growth and diversity. Several other issues, not addressed in our paper, are important to us. We feel that there is a need for a separate Physical Layer document. Such basic issues as: framing, error detection, contention guidelines, modulation schemes and bandwidth limitations should be defined in this document. Some differences may also be required when operations are conducted in contention, point-to-point and multi-cast environments. We feel that the following basic points should be incorporated into the document: 1. HDLC frames should be used by Amateur Radio packet mode stations. 2. Bit-synchronous packet mode operations should follow the format specified by the HDLC protocol. 3. Asynchronous packet mode operations should be as specified by the HDLC protocol and the proposed "Asynchronous Framing Technique" currently being considered by ISO. 4. Some form of exponential back-off procedure should be used when re-transmission is required. The proposal by Phil Karn would be fine. Certain other issues of concern to us are: 1. The default user data field size for AX.25 Link Layer (only) DXEs should be 256 octets. The Frame Window size should default to 2. Larger maximum frame sizes could be considered use useful in high speed environments. A maximum user data field length of between 1024 and 4096 octets seems reasonable. Maximum window sizes could be increased but only when the window size causes DXE's to be flow controlled while waiting for "RRs". 2. The default user data field size for Amateur Radio X.25 DXEs should be 256 octets. The X.25 Packet Window should default to 2. A maximum user data field length of between 1024 and 4096 octets seems reasonable. Maximum window sizes could be increased but only when the window size causes DXE's to be flow controlled while waiting for "RRs". 3. We would like to see the full X.25 protocol incorporated as an option defined in the AX.25 specification. This would be possible by placing all Amateur Callsign and Station octets before the standard X.25 Link Layer Address (01H or 03H) and Control fields. The proposals we have made will facilitate such a move in future. Such steps will also provide the basis for Amateur Radio Networking Standards to one day be referenced in ISO and CCITT standards documents. 4. We would like to see extended Frame and Packet Sequence Numbering used (as an option) on satellite circuits or other environments where there is significant propagation delay. Other areas which should be investigated during the first part of 1988 include the possible addition of a standard protocol for remote DXE parameter reading and setting. A specification for the definition of locally and remotely controllable packet interface parameters would also be desirable. Maybe this should include a definition of standard device support (eg. ANSI X3.64, or TTY). We are also wondering when the task group chartered to investigate message systems will get together. There seems to be a good basis of agreement between the CCITT X.400 Message Handling Systems and ARPA RFC822 crews in a convergence document called RFC 987. RATS has already implemented a portion of the common elements as outlined in RFC987 in its BBS software, PRMBS (Packet Radio Mail Box System - by KA2BQE based on an early release of the W0RLI "C" BBS). Who are the other members of the group ? In any case, we are looking forward to the meeting on the 9th of January. If there is anything we can do before the meeting to improve the quality of the work, please let us know. Please circulate this letter and the enclosed draft paper to the anticipated attendees of the January meeting and others who might comment on the text. Vy 73, J.

Gordon Beattie, Jr., N2DSY Thomas A. Moulton, W2VY The Radio Amateur Telecommuications Society 206 North Vivyen Street Bergenfield, New Jersey 07621 29 December 1987 DRAFT ABSTRACT -------- In this paper we offer improvements to the AX.25 Link Layer protocol header. In order to provide a more complete picture of the problems with the existing header, we have described the current header and provided a list of frequently requested changes which would help make the protocol more flexible. The proposed revised format addresses the needs of a wide variety of users including the users of the CCITT connection-oriented X.25 (ISO 7776/8208) protocol, the ISO Connectionless ISO 8348 AD1 (ISO IP) protocol, the DoD Internet Protocol and the existing Layer 2 Terminal Node Controllers. These users may be found in the Amateur Radio Service, Military Affiliate Radio Service, commercial radio services, and government radio services. Further changes have beeen included to address requirements imposed on the Amateur Service by foreign telecommunications administrations. Consideration of other services and administrations has helped mold the revisions proposed in this document. This "external" influence has been a positive component in the re-specification process. INTRODUCTION ------------ This paper has been written to introduce members of the Amateur Radio community to the need for changes to the current Amateur Radio AX.25 Version 2 Link Layer Protocol. We have outlined a proposal for a revised AX.25 link layer protocol and provided the rational for the changes. It should be pointed out that the proposed changes do not change the logic of existing AX.25 Link Layer implementations, but requires that frame format changes be made to the header. These changes are sweeping in the flexibility they offer, but not in the effort required to implement them. CURRENT HEADER ------- ------ The basic format of the existing layer 2 frame is: Flag / Address / Control / Protocol ID / User Data / FCS / Flag The header of the AX.25 frame has three components which we will address: 1. Address field, 2. Control field, 3. Protocol Identifier. The Address field of the AX.25 frame header currently supports a Destination callsign (DST), a Source callsign (SRC) and up to eight digipeater callsigns: VIA1-VIA8. This is shown below: DST / SRC / VIA1 / VIA2 / VIA3 /.../ VIA8 Each field contains six uppercase, numeric or SPACE characters coded in ASCII. Each callsign is followed by an "SSID" byte which is used to discriminate between multiple stations operating under the same callsign. These characters are "bit-shifted" so that the low order bit is filled with a "0". The last octet in the Address field contains a "1" in the low-order bit position. This is in accord with the HDLC address field extension procedures. The Control field contains frame type and data flow information. Its use is fully defined by HDLC and no changes are required. The Protocol Identifier (PID) is used to reflect the Layer 3 protocol capabilities (if any) of the system. Values have been assigned for systems supporting X.25 packet layer (layer 3) and the Internet suite of protocols. If no layer 3 protocol is supported by the system, then the octet is encoded as a "0F0H". REQUESTED CHANGES --------- ------- There have been several requests for changes to the Address field which will help make the protocol more useful to Amateurs and other users. These have taken various forms including: 1. Expansion of the Address length to a number greater than six characters, 2. Variable length Addresses, 3. Support for a reciprocal/portable/mobile operating prefix in the callsign, 4. Extension of the SSID field to more than 16 values, 5. Simplification of the handling of SSIDs, 6. The addition of a "FROM" Address if different than the Source Address, and the addition of a "TO" Address if different than the Destination Address, 7. Simplification of the "has been repeated" signal, 8. Simplification of the Command/Response signal, 9. Improved alignment of the AX.25 link protocol with the X.25 link protocol, 10. Support for ISO Connectionless Network Layer (ISO 8348 AD1), 11. Support for the US DoD Internet suite, 12. Support for the vanilla level 2 "TNC" user, 13. Support for vendor specific extensions, not part of the protocol, 14. Distinction from existing protocol implementations, 15. Capability to signal future extensions to the protocol. PROPOSED LAYER 2 HEADER -------- ----- - ------ The proposed header has the following basic format: Flag / Address / Supplementary Address Field / Control / User Data / FCS / Flag The Address field will contain the Source and Destination addresses. Each field will be preceeded by a length octet expressed as a binary value and then bit-shifted up (X2) to conform to the encoding rules for HDLC address fields. The length octet is not counted as part of the address length. The Destination and Source Address fields may each contain up to 31 octets. Valid values are the characters 0-9, A-Z, slash ("/") and the hyphen ("-"). The slash may only be used to separate a station callsign from a reciprocal or mobile/portable operating ID (eg. GW0/WB2XYZ or 4X4FN/W2). The callsign sequence may be followed by a hyphen and other characters used to identify a unique instance of the station authority. An example may be: N2DSY-2 or N2DSY-UNIX The hyphen and additional characters will be called an "System Identifier" or "SID". The callsign and the "SID" comprise an Address. Again, this sequence may not exceed 31 characters. The Supplementary Address field will contain facilities to communicate a "FROM" Address (optional), a "TO" Address (optional), Digipeater Addresses (optional), and upper layer protocol capability (mandatory). The "FROM" Address (FRM) field contains the callsign and "SID" of the station which orginated the packet if different than the "Source". It needs to be included ONLY when regulatory administrations require such identification on a per frame basis. It will be preceeded by a tag character coded as an ASCII "F" (46H) bit-shifted up (X2) to conform to the encoding rules for HDLC address fields. The octet following will contain a length octet reflecting the length of the Address in the remaining part of the field. The "TO" Address (TO) field contains the callsign and "SID" of the station which is to receive the packet if different than the "Destination". It needs to be included ONLY when regulatory administrations require such identification on a per frame basis. It will be preceeded by a tag character coded as an ASCII "T" (54H) bit-shifted up (X2) to conform to the encoding rules for HDLC address fields. The octet following will contain a length octet reflecting the length of the Address in the remaining part of the field. The Digipeater Address field(s) contain(s) up to eight address sub-fields, VIA1 through VIA8. Each of these Digipeater Addresses may contain a callsign and an "SID". Each digipeater address field will be preceeded by a tag character coded as an ASCII "R" (52H) or ASCII "r" (72H). The "has been repeated" condition will be signalled by through the use of the lower case "r" (72H). The "unrepeated" condition will be signalled through the use of the upper case "R" (52H). The octet following is the length which will be expressed as a binary value and then bit-shifted up (X2) to conform to the encoding rules for HDLC address fields. The length octet is not counted as part of the address length. The VIA1-VIA8 Address fields may each contain up to 31 octets. The upper layer protocol identifier (ULPID) will be an odd value (except as noted in the table below). The upper layer protocol identifier may be signaled as follows: 01 - CCITT X.25 DXE implemented 03 - CCITT X.25 DXE implemented 81 - ISO 8748 AD2 Protocol implemented on AX.25 Link 83 - ISO 8748 AD2 Protocol implemented on AX.25 Link 8D - ISO 8748 AD2 Protocol implemented on AX.25 UI Frames 8E - Escape value - Reserved for future use by the OSI community AE - Escape value - for vendor extensions - not part of the protocol C1 - DoD Internet Protocol implemented on AX.25 Link C3 - DoD Internet Protocol implemented on AX.25 Link C5 - DoD Internet Address Resolution Protocol implemented on AX.25 Link C7 - DoD Internet Address Resolution Protocol on AX.25 Link CB - DoD Internet Address Resolution Protocol on AX.25 UI Frames CD - DoD Internet Protocol implemented on AX.25 UI Frames CE - Escape value - Reserved for future use by the Internet community F1 - No upper layer protocol implemented on an AX.25 Link F3 - No upper layer protocol implemented on an AX.25 Link FD - No upper layer protocol implemented on an AX.25 UI Frame FE - Escape value - reserved for future use. Note that each of these values (except the Escape values) provides a valid terminating octet for an HDLC address field. Each value is odd except where noted above. SUMMARY ------- In this section we will summarize the proposed changes to the AX.25 Link Layer Protocol and show how each change provides a realistic solution to a particular open issue. Issues 1, 2, 3, 4, and 5: 1. Expansion of the Address length to a number greater than six characters. 2. Variable length Addresses, 3. Support for a reciprocal operating/portable/mobile prefix/suffix in the callsign, 4. Extension of the SSID field to more than 16 values, 5. Simplification of the handling of SSIDs, Response: Each Address field may contain up to 31 characters. This provides adequate space for an Amateur Callsign or other identifier. There is a length octet before each Address field which provides a reasonable address space. In this proposal the callsign and reciprocal operating prefix is considered to be part of the callsign portion of the Address. The System Identifier (SID) provides space for many systems to be operated under a common license. Its only limit is 31 octet less the number of callsign octets. The SID is processed in a manner identical to the way callsign characters are processed. No special processing is required to extract the value. Issue 6: 6. The addition of a "FROM" Address if different than the Source Address, and the addition of a "TO" Address if different than the Destination Address. Response: There has been some call for a way to indicate the Address (Callsign et al) of the end-point stations when operating through a network. The Link Layer Address fields Destination and Source reflect the Addresses of the stations operating over the current link. They do not however reflect the originator (FROM) or the terminating (TO) Addresses. Some administrations, not realizing that other methods can be used to determine this information have placed such requirements on Amateurs under their control. In several cases, the inability of the protocol to provide this information has forced Amateurs to remove advanced networking units from service. This capability should remove such problems. Issue 7: 7. Simplification of the "has been repeated" signal. Response: The Repeater Address fields have been prefixed by an octet which, depending on coding, indicates "unrepeated" and "has been repeated" status. They are the ASCII values "R" and "r" respectively. As with the SID, no special process is required to derive the repeated status. Issue 8: 8. Simplification of the Command/Response signal. Response: The Command/Response signal is provided by using two sequential odd values for the ULPID octets. These value pairs are negotiated during initial link setup. The sender of the SABM will use the lower of the two values. Since these values are only valid for stations using LAPB, a third value of ULPID has been defined for use with the UI frame. Issues 9, 10, 11, and 12: 9. Improved alignment of the AX.25 link protocol with the X.25 link protocol, 10. Support for ISO Connectionless Network Layer (ISO 8348 AD1), 11. Support for the US DoD Internet suite, 12. Support for the vanilla level 2 "TNC" user, Response: The table in the last section contains a detailed list of a wide variety of supported Upper Layer Protocol Identifiers (ULPIDs). Each community of interest has been provided with a flexible mechanism by which the use of upper layer protocols may be signalled. Many of the more difficult Link Layer protocol issues (eg. Frame size, Window size and elements of procedure) may be more easily resolved by allowing the default parameters of operation to be set on a per user group (X.25, ISO IP, Internet, etc.) basis. The ULPID provides a mechanism to signal the upper layer protocol and (in this environment) to imply default operational parameters. Issue: 13. Support for vendor specific extensions. Response: There is an ULPID extension value defined in the table above, which provides a mechanism for vendor-specific extensions to the protocol. As proprietary extensions, they are not part of the protocol, and no other implementation is required to support such extensions for purposes of conformance to the protocol. Software 2000's NET/ROM protocol would probably fit into this category. Issue: 14. Distinction from existing protocol implementations. Response: The first octet of the HDLC Address field will now contain values in the range of 0 to 1FH. Values found in the first octet of the current header (Version 1 or 2) have values above 30H. Determination of "old" vs "new" implemtations can easily be based on this difference. Issue: 15. Capability to signal future extensions to the protocol. Response: Several extension values have ben provided for the overall protocol and for specific interest groups. These should allow the protocol to be extended in ways appropriate to the user community. CONCLUDING STATEMENT ---------- --------- The primary objective of this proposal was to meet most of the outstanding needs of the various users of the AX.25 protocol. It is felt that this proposal provides the needed changes and flexibility for the various users of the protocol. Much effort was made to provide a framework for growth and independence for each of these communities. It is hoped that the proposal addresses most of their needs. If further considerations must be made, we will incorporate them into an appropriate revision of this document. A lot of thought and "soul-searching" has gone into the proposed changes outlined in this document. It is hoped that similar effort is made by those providing comments. 10-Jan-88 16:04:52-EST,1713;000000000000 Received: from EDDIE.MIT.EDU by DEEP-THOUGHT.MIT.EDU via Chaosnet; 10 Jan 88 16:04-EST Received: by EDDIE.MIT.EDU with sendmail-5.45/4.7 id <AA03403@EDDIE.MIT.EDU>; Sun, 10 Jan 88 15:10:56 EST Received: by EDDIE.MIT.EDU with sendmail-5.45/4.7 id <AA03393@EDDIE.MIT.EDU>; Sun, 10 Jan 88 15:10:39 EST Message-Id: <8801102010.AA03393@EDDIE.MIT.EDU> Received: from MITVMA.MIT.EDU by MITVMA.MIT.EDU ; Sun, 10 Jan 88 15:11:07 EST Received: from FINTUVM.BITNET by MITVMA.MIT.EDU (Mailer X1.25) with BSMTP id 0657; Sun, 10 Jan 88 15:11:03 EST Received: by FINTUVM (Mailer X1.25) id 7268; Sun, 10 Jan 88 22:02:31 EET Date: Sun, 10 Jan 88 21:45:37 EET From: Matti Aarnio <FYS-MA%FINTUVM.BITNET@MITVMA.MIT.EDU> Subject: Re: subscribe packet-radio To: packet-radio@eddie.mit.edu In-Reply-To: Message of Fri, 8 Jan 88 16:21:42 MEZ from <I2010506%DBSTU1.BITNET@CUNYVM.CUNY.EDU> >HELP >SUBSCRIBE PACKET-RADIO I2010506@DBSTU1.BITNET Christian Boettger >SUBSCRIBE PACKET-RADIO Christian Boettger >I2010506@DBSTU1.BITNET Well, Christian did assume that original list behaves similar to LISTSERV-lists on BITNET.

I am running an 8 Mhz AT with Uport 2.3.0U, 92MB disk in two drives, 3 MB RAM and an 8-port "dumb" Digiboard serial card. For the most part, the UNIX version works ok. It does have a tendancy to core-dump every now and again with a memory fault. We're getting this on both mine and KA3ADU. This is not the final version and I beleive several of the problems are being resolved. But overall, Im happy with the operation of it on Uport.

Keywords: NTS PBBS Packet Area Codes ZIP The Radio Amateur Telecommunications Society 206 North Vivyen Street Bergenfield, New Jersey 07621 29 December, 1987 Mr. Rick Palm ARRL 225 Main Street Newington, CT 06111 Dear Rick: I am writing to you in reference to a matter of great importance to us. There has been a bit of misinformation circulating in some ARRL publications regarding the actions of the NTS Eastern Area Staff (EAS) pertaining to packet radio operations. It seems that in the ARRL Letter, Gateway, and possibly several other publications there was a report that indicated that the NTS EAS had endorsed only "ZIP code addressing for routing of radiograms through the emerging PBBS autoforwarding network". This quote was obtained from page one of the November 20, 1987 issue of Gateway. It reflects a credit to the ARRL Letter. What was published was not the whole story. The motion that was passed UNANIMOUSLY provided for the use of ZIP codes, two letter State abbreviations, AND TELEPHONE AREA CODE/EXCHANGES for routing NTS traffic through Amateur Packet message systems. We are at a loss to understand how such a sweeping proposal could somehow be misquoted. What is important is the logic used by the NTS Eastern Area Staff in deciding to provide such flexibility. The members felt that there were situations where any of these mechanisms would be optimum, and as such, each should be supported by packet messaging systems handling NTS traffic. Apparently they are not alone in this approach. W9ZRX compiles a BBS list and he requests that each of the addressing formats be provided by system operators wishing to list their systems. Flexibility seems to be the name of the game here. A second motion passed by the staff directed that: "a study of specific proposals made by members of the Northeast-based Radio Amateur Telecommunications Society (RATS) for NTS user interface with the system" be made by the Regional Packet Managers. They are to report on their findings by March, 1988. This motion was made after a presentation made by Thomas A. Moulton, W2VY and me on the role of existing PBBS header elements in a migration of NTS and PBBSs in general, to more flexible mail schemes such as those used by the CCITT X.400-based Message Handling Systems and Arpanet RFC822 mail systems. Support for some of the additional header elements common to these systems has already started in the RATS PRMBS (KA2BQE) and the MBL Mailbox (WA7MBL) PBBS packages. We look forward to working with the Regional Packet Managers on this important project. After the first of the year we expect to hear from them and finally get started. I have also enclosed an Area Code file for your reference and possible publication. We hope that you can publish news items which alert the Amateur Radio community to the mistatements made previously and hopefully rectify some of the misconceptions that exist on this issue. Vy 73, J. Gordon Beattie, Jr. N2DSY Chairman, RATS cc: Doug Zuckerman, Chairman ARRL NTS EAS Stephen Mendelsohn, Director ARRL Hudson Division Paul Rinaldo Stan Horzepa Members of the Board, RATS The following list is provided as a service of the Radio Amateur Telecommunications Society to assist packet mail system sysops and users set up Area Code routing tables. As per a recent ARRL National Traffic System Eastern Area Staff motion: Telephone Area Codes and Exchanges may be used as alternatives to Zip Codes or two letter state abbreviations for the purposes of routing messages. We have also compiled this list because the RATS COSI-Switch uses the Telephone Area Codes as part of its addressing plan for North America. When used here in North America, users will not need to supply a country code (as per CCITT X.121) when making connections. These will be provided automatically by the network nodes. International operations will be based on the same CCITT country code plus national numbering plans. An automatic remote BBS connection routing capability will also be provided by the RATS COSI-Switch based on the same addressing plan. Each switch will have a list of local BBS systems in its configuration. A remote user or system wishing to forward mail to northern New Jersey need only connect to "BBS" at "201".

The doc files are mainly related to the dos world but have been able to "translate" some of the info over to unix. First problem is how do you do an attach for a serial line? the DOC say to give the addres and interupt, attach asy 0x2f8 3 slip.... but what about under unix, I am not running on a PC clone so address and interrupt will not work. I have tried putting a /dev/ttyxx in the field(s), and lights on my breakout box comes on, but if I exit net, light dont go out. Also bm will not compile on my SYSV box, make coplains about timezone and ltm being redefined and time_t being unfdefined. Since I dont have my kiss tnc in yet, can I talk to myself with net? I seem to be able to ftp files and telnet to the echo server, but never get a login prompt if i just to a telnet [node], IS the login server the default telnet sever? Is there even a preliminary manual for unix installation of net? many thanks... -- Gary W.

Karn) To: PACKET-RADIO@EDDIE.MIT.EDU Subject: Re: Need some TCP/BM help Summary: tcp help References: <443@wa3wbu.UUCP> Hi John, Yes, you can run TCP/IP through a digipeater. However, it takes a little more effort than running direct. The difference is that in direct mode, a technique called "ARP" (Address Resolution Protocol) automatically discovers the AX.25 callsign belonging to a desired IP address. However, it uses a broadcast technique (ARP request packets are sent to "QST-0") and that doesn't work through digipeaters. So you have to use the 'arp" command to put an entry into the table manually, and it gives you the option of adding a digipeater to the path as well. All that is documented in the user manual under the "arp" command. As for problems with BM, it appears you may not have set up your /hosts.net file with all the necessary entries. Why don't you send mail to nn2z@ka9q.bellcore.com? Dave has been doing a lot of work on BM and the related facilities and he can probably help you out. Thanks for the interest in net.

You have to manually set up an ARP entry for every station to whom you have to digipeat. Something like: arp add feeble-pc.ampr ax25 wf3eeb-1 wl3oud where feeble-pc's ax25 address is wf3eeb-1 and the digipeater is wl3oud. If you need a string of digis, just list them all, I think with commas between them, but I don't remember. The station on the other end will need a similar line. Also, if they can't hear you but you can hear them, they can put in an arp line without a digipeater specified, which will make them transmit to you directly. > The other problem seems to be the mailer (BM.EXE).

I can look in /spool/mqueue and the messages are in there but >it wont report or read them from the prompt. Well, first thing to note is that mail from you, to you, is not delivered until smtp does it. So, you need to exit mail, kick smtp, wait a bit, *then* check. >If I send mail to >"lester@ka3adu" and then initiate an "smtp" the following occurs: > >Net> smtp kick >smtpcli: unknown address wa3wbu.ampr >[same line 5 times] >smtpcli: unknown address wa3wbu Well, are you in your own hosts.net?

Like if he sent "mail john@wa3wbu", then my DIR of /spool/mail shows >a DOS filename of "AIL JOHN.TXT". Try "m john@wa3wbu". I think the parser in BM is a bit simple minded, and thinks the addressee is "ail john". Be aware that you gotta get the host addresses just the way they look in your hosts.net. If you want to have an alias or a shortened address, I think you'll have to put in another entry for it.

It has only core-dumped on me once with a memory fault. At the time it did, I had two telnets, two FTP's and an AX.25 session up. When I went to switch to the one FTP session, it dumped and logged out my terminal. I have a seperate login for Net which plops me into a directory where all the net stuff is. Its on virtual console9 (Could be any though). When Net core dumps, it does log out this terminal. I have nothing so to speak in my .profile. I have no problems in running multiple virtual consoles.

I have a PK-87, and I have experienced precisely the problems you describe. I did find that sometimes the FLOW feature (that keeps the TNC from sending to you when you have a line pending) appears to interfere with proper software flow control, but I still sometimes experienced mangled files. I spoke to AEA about it, and they said they had increased the number of characters they could accept after they sent an XOFF. I'm still waiting for the new firmware they were going to send me, so I can't report on whether they've fixed the problems. I strongly suggest that you speak to their tech support people, because the fellow I spoke to said I was the first one to report difficulties with flow control. I've given up sending files through the PK-87's AX.25 software. Now if I have to send something to a BBS, I put the TNC in KISS mode and use the AX.25 support in KA9Q's excellent TCP/IP package. No flow control problems there! 73, Dan W9NK 11-Jan-88 18:58:19-EST,2219;000000000000 Received: from EDDIE.MIT.EDU by DEEP-THOUGHT.MIT.EDU via Chaosnet; 11 Jan 88 18:58-EST Received: by EDDIE.MIT.EDU with sendmail-5.45/4.7 id <AA22895@EDDIE.MIT.EDU>; Mon, 11 Jan 88 15:37:38 EST Received: by EDDIE.MIT.EDU with sendmail-5.45/4.7 id <AA22876@EDDIE.MIT.EDU>; Mon, 11 Jan 88 15:36:39 EST Received: by june.cs.washington.edu (5.52.1/6.11) id AA21756; Mon, 11 Jan 88 12:38:13 PST Return-Path: <ames!umd5!brl-adm!cmcl2!phri!dasys1!kb7uv@EDDIE.MIT.edu> Message-Id: <8801112038.AA21756@june.cs.washington.edu> Date: 28 Dec 87 03:34:46 GMT From: ames!umd5!brl-adm!cmcl2!phri!dasys1!kb7uv@EDDIE.MIT.edu (Andy Funk) To: PACKET-RADIO@EDDIE.MIT.EDU Subject: PBBS Programs Keywords: Packet BBS Programs I'm attempting to compile a list of Packet Bulletin Board programs. So far I've seen others are keeping lists of just about everything else for packet, but this seems to have been forgotten. If you have written, or know of, a packet radio BBS (PBBS) program, please send me some info on it. Specifics I need to know are: What machine does it run on? Is a certain amount of RAM needed? Disk Drives? I/O options? Which TNCs are supported? Will it forward W0RLI standard "mail?" Who is (are) the author(s)? How is the program available? Public Domain? Shareware? Commercial? Other? Special features? Also, does the program have any features which make it specially suited for use as a "personal mailbox?" (A "personal mailbox" is a PBBS operated for an individual, the sysop, no "users." It is used to provide automated delivery of incoming messages and automated transmission of outgoing messages, via a "host" PBBS.) All data gathered will be shared with the Amateur Packet Radio community via USENET, CompuServe, Packet, and possibly publication.

I was playing around with it on my UNIX machine which utiltizes software flow control on the ports and I was unsuccessful at finding options for enabling software flow control in the converse mode. I'm currently using a TNC2 and by setting FLOW & XFLOW on, it responds to software flow control. The manual for the PK-232 seems to indicate that its soft flow control is only active during TRANSPARENT mode. And indeed, it does appear to work in TRANS. But when attempting to send large files in CONV (Like uploading to a BBS) I seem to loose data. It works fine however with hardware flow control when hooked to my DOS machine. I have properly set the START and STOP parameters. Any ideas ?? If it makes a difference, I am running Microport 2.3 on an AT-clone.

I think you'll find most of the Los Angeles TCP/IP activity on 145.36, along with other protocol experimentation. Here in San Diego, the "preferred channel" is 144.76. High-speed stuff is on 220MHz or 441.5. As for assigning addresses, there is already a block assigned for the Los Angeles area, according to my records - Don, WB5EKU is the address coordinator for that area. I have agreed (well, been badgered into) taking over address block assignments for areas that have not already been assigned an AMPR address block. If you had a request pending with Wally, please send it to me and I'll take care of it as soon as I get organized. My address is below at the end of this overly-prolix message. There are nearly 500 hosts registered in the AMPR address database so far. Hostnames are assigned within the AMPR domain as follows: for a single host: wb6cyt for multiple hosts: sun.wb6cyt pc.wb6cyt etc.wb6cyt These would appear in the hosts table as 44.8.0.1 WB6CYT # Brian Kantor, San Diego CA 44.8.0.101 3b2.wb6cyt 44.8.0.102 pc.wb6cyt 44.8.0.103 sun.wb6cyt 44.8.0.104 unix-pc.wb6cyt 44.8.0.186 ps186.wb6cyt The fully-qualified domain name would be <the above>.AMPR.<top>, whatever the NIC finally gets around to deciding <top> should be. Thus a hostname might well be something like ps186.wb6cyt.ampr.exp if they wind up stuffing us in the (imaginary) EXPerimenters domain. For people ACTIVELY EXPERIMENTING with TCP/IP on packet radio (i.e., you've got the station on the air and are doing more than just typing keyboard-to-keyboard and saying "gee whiz" about it), there is a mailing list for technical discussions and arguments. If you are interested in subscribing to that list, send mail to 'tcp-group-request' at the hostname below and explain what it is you are doing. The list is getting large enough that I'd prefer NOT to add just lookers-on, since we get some pretty rapid-fire and heated (and occasionally abusive) discussions going on, as is common any place that technoids congregate. UCSD is reachable from uucp, the Darpa Internet, BITNET, SPAN, and other wonderous communications media. Don't call me on the phone.

The 8086 family interrupt mechanism is slow enough without having to invoke it for every single character that is sent or received. There are people running net.exe at serial line speeds of 9600 baud and up full duplex, so efficiency is very important. Looks like the braindamaged standards set by IBM software have struck yet again. The one saving grace of the PC is that you can always thumb your nose at IBM and talk to the hardware if necessary.

Phil Normally, I just ignore the stupid blasts back and forth between the TCP/IP and X.25 crowds, since the information content has dropped to zero. But this one is a little too much. 1) "All you need is a callsign": The referenced message was about NTS traffic, which generally is to people who have NO callsigns. That problem needs a solution, whichever transport/network protocol you use. 2) "routing codes visible to the user": At present, the ham TCP/IP users ARE the sysops. Or did I miss the BBS option in a recent release? And the sysops/users sure do have to deal with routing. 3) "the rest is handled automagically": Darn. I must have missed the routing and name/address server demons in the distribution, too. Seriously, a callsign was all you needed in the AX.25 network when they had as few active stations as we do now in ham TCP/IP. They all fit in a short routing table (handled by the sysops) back then, too. Let's get real, guys. (For the record, I do both TCP/IP and X.25 at work, and do TCP/IP and NTS and AX.25 at home.

Karn) To: PACKET-RADIO@EDDIE.MIT.EDU Subject: Re: Wild shots Summary: addressing vs naming References: <7887@eddie.MIT.EDU> Bob, I was only trying to point out something that I think has been lost in the din of the area-code vs zip-code wars: Names are not addresses! Addresses are not names! For a network to be truly easy to use, there must be a clean separation between these two concepts. Addresses may be chosen for the network's convenience (i.e., to simplify routing) but names are chosen for the convenience of the human user. Every network requires *some* sort of database to do name/address translation. If you "simplify" your network by requiring the user to give network addresses, you've merely forced him to keep his own database, most likely in his head! (The telephone network is a good example). Computer processing and storage is cheaper now than it's ever been, and it's only getting more so. I therefore reject the notion that it is somehow "cheaper" to force humans to memorize lists of numbers than to store them in a computer. Whether the name/address database is stored in a centrally-maintained host table or with a distributed name server is an (albeit important) implementation detail. I wasn't really referring to NTS. Rather I was talking about the various proposals to route traffic BETWEEN AMATEURS using zip codes or area codes. I see NTS as a sort of "super internet", where the ham packet Internet is just a "subnetwork" in an even larger system that also contains phone and CW traffic nets. "Names" in the amateur Internet therefore become "subnetwork addresses" to NTS, and it's really up to them to decide what kind of message formatting, addressing and routing they want to layer on top of us; it really doesn't matter to me.

I have yet to aquire a TNC, and also plan to dedicate a transceiver to it. I would like to get specific recommendations for a 144 Mhz transceiver to be dedicated to packet. 1. It does NOT have to be synthesized. A crystal controlled model should have at least 8 channels. I hear that crystal is better but that synthesized rigs have improved. 2. It should have quick switching times appropriate for packet operations. 3. A sister model for 220 Mhz would be a big plus. 4. It needs to be fully usable for voice, i.e. mic connectors, repeater splits, etc. 5. 12 VDC operation would be a big plus, but 110v AC only is acceptable. I have a Kenwood PS-50 power supply I can drive it from for a while. 6. It does not have to be a new model, if an older one works well. 7. I would be interested in paying up to $450 for a new model.

Karn) To: PACKET-RADIO@EDDIE.MIT.EDU Subject: Amateur TCP/IP path contest Now that TCP/IP is really starting to take off in the amateur world, I think it would be fun to start a running contest. The goal is to see who can come up with the most complex, ad-hoc Internet path involving one or more amateur packet radio links. This is inspired by Mike O'Dell's famous "worst wire" contest. The only requirement is that the path must actually work! At a minimum, you must successfully complete a three-way TCP handshake and then successfully close the connection. To start things off, I'd like to describe an experiment we did last weekend. As many of you know, Telenet has this nifty service called PC Pursuit. From any Telenet access number, you may connect to a remote dialout modem in in something like 6 metropolitan areas. As long as you use it only during evenings and weekends, it costs $25/month -- flat rate! Several amateur TCP/IP groups have begun using PC Pursuit to link their otherwise isolated "islands", with excellent results. Last weekend Al, WB0MPQ (another resident of Warren, NJ) dialed up a PC Pursuit link to Brian, WB6RQN, in the Maryland suburbs of DC. While the link was up, I had Bob, WA3PXX, telnet briefly to a Bellcore machine named "sabre" in Navesink, NJ. The path was as follows: Node, location Link/Subnetwork ---- ---- ---------- wa3pxx.ampr (PC/XT) 222.06 Mhz AX.25 link duplex RF repeater Gaithersburg, MD(?) 223.66 Mhz AX.25 link wb6rqn.ampr (PC/AT) Germantown, MD SLIP on 1200 baud dialup phone line (C&P Tel) Telenet dialer port Washington, DC GTE Telenet X.25 network Telenet TIP port Rahway, NJ SLIP on 1200 baud dialup phone line (NJ Bell) wb0mpq.ampr (PC/XT) Warren, NJ 147.525/430.05 Mhz full duplex AX.25 link switch.ka9q.ampr (PX/XT) Warren, NJ KA9Q shack Ethernet sun.ka9q.ampr (Sun 3/75) SLIP on 9600 bps dialup phone line (NJ Bell) Micom terminal switch Piscataway, NJ T-1 leased line (portion) (NJ Bell) Micom terminal switch Morristown, NJ hardwired RS-232 line doomsday.bellcore.com (Sun 2/170) Lab Ethernet Ethernet repeater Machine room central Ethernet DEC Lan Bridge Building backbone Ethernet Ethernet repeater Building "core" Ethernet Vitalink Translan T-1 leased line (portion) (NJ Bell) Vitalink Translan Piscataway, NJ T-1 leased line (portion) (NJ Bell) Vitalink Translan Navesink, NJ building backbone Ethernet DEC Lan Bridge Building wing Ethernet DEC Lan Bridge Lab Ethernet sabre.bellcore.com (Vax 11/750?) ...and back. This was a direct end-to-end connection; the TCPs on wa3pxx.ampr and sabre.bellcore.com spoke directly to each other. Excluding the endpoints themselves, the path their IP datagrams took included: 8 Ethernets 5 IP gateways (2 Suns, 3 PC's running KA9Q net.exe) 4 radio frequencies on 3 amateur bands 3 dialup phone links (2 @ 1200 baud, 1 @ 9600 baud) 3 T-1 digital leased lines with multiplexors 3 Vitalink Translan IIIs 3 DEC Translan 100s 2 Micom terminal switches 2 Ethernet repeaters 1 full duplex RF repeater 1 public X.25 network (Telenet) 1 partridge in a pear tree :-) So...can anybody top this?

This discussion is motivated by the weight of evidence which indicates that X.25 is not well suited for a multiaccess environment, nor was it ever designed to be. Other considerations exist, not limited to the following: 1. Protocol Thrashing in common multiaccess environments. 2. Difficulty in implenting the protocol; in particular, the expense of the chips required to perform the protocol. 3. Lack of persistence / backoff algolrithm. 4. Connection orientation of the protocol. Admittedly, these shortcomings were probably not know to the designing committee (although they should have been aware of them, since the results of academic research into packet radio were widely available). Even given this consideration, however, AX.25 is of minimal utility, except for the fact that it exists, and the FCC allows unattended operation of it. As a replacement, I would propose the AppleTalk / AppleLink protocol as described (thoroughly) in _Inside Appletalk_, which is available from APDA for a nominal fee. In particular: 1. AppleTalk was designed for use in a CSMA environment, by an individual who did his dissertation work in packet radio. 2. The protocol is relatively straightforward, and is easy to implement using less expensive chips (such as the 8530). 3. The top speed of most of the protocol implentations exceeds that of AX.25 by an order of magitude. As a test of the protocol, I'm currently working on an inexpensive (cf. $1k) microwave AppleTalk system as part of my dissertation work (see the March 1988 issue of MacWorld for more info). I would welcome and appreciate any comments on this proposal. -=Paul Flaherty, N9FZX | "The only thing that we've learned from Computer Systems Laboratory |history is that we havn't learned anything Stanford University |from history..."

Amateur Radio is for experimentation for the fun of it. Don't ask me to go to a standards committee meeting but playing with appletalk over radio links sounds like fun even if it may never be a "standard". When a node comes up on an AppleTalk network it assigns its self a random number as a node number and broadcasts it saying "here I am anybody using this node number????". This seems inappropriate to a packet radio net where almost by defenition not all nodes can hear each other. Do you have a solution to this problem? Even if you don't have an answer to this problem if you have a simple scheme to hook a macintosh up to a modem and radio it might be fun to try out.

Karn) To: PACKET-RADIO@EDDIE.MIT.EDU Subject: Re: Amateur TCP/IP path contest References: <1712@faline.bellcore.com> I should add that I actually have a serious purpose behind the "most complicated amateur Internet path" contest. The idea is to get people thinking about how they might assemble an ad-hoc computer network in an emergency using whatever communication facilities might be available, amateur or otherwise. It is unrealistic for us to say "we're hams, so we're not interested in anything that doesn't use ham radio", or to look down on using commercial facilities in an amateur network as "cheating" even when there is no amateur alternative. In many communities, the hams are the people who are also the most knowledgeable about communications in general -- not just radio. I therefore believe we have an obligation to offer our skills as "communication system integrators", not just as providers of POT-WARS (Plain Old Two-Way Amateur Radio Service). In an emergency, pragmatism rules supreme, and getting the traffic through is the only thing that counts. If picking up the phone is the best way to do it, then so be it (assuming, of course, that the phone still works). As an example of a hypothetical emergency situation where a hybrid amateur/commercial computer network might be extremely useful, consider a major earthquake in Los Angeles. (This is "The Big One", the magnitude 8+ quake that has a better than 50% chance of hitting southern California sometime in the next 30 years). Local utilities (power, telephone) are completely destroyed for many tens of miles. However, the phones a hundred miles away are still working, and of course the remainder of the country is unaffected (except for long-distance telephone trunks that would be routed through LA). There is an urgent need for record communications from the city to places all over the country, first to carry official emergency traffic (requests for rescue equipment and assistance, etc) and later to carry personal health and welfare messages from the survivors. In this situation I would envision portable and mobile amateur packet radio stations (consisting of a laptop computer, TNC/modem, radio and battery power) in the disaster areas. Packets would be relayed on amateur and/or public service frequencies using either analog or digital repeaters to gateway stations in areas where the phone service is still operating. There they would enter an ad-hoc "backbone network" composed primarily of personal computers switching packets between modems on dialed-up phone lines, but also using whatever else the operators can get their hands on: amateur, government and commercial HF and satellite circuits, commercial X.25 networks like Telenet and TYMNET, government-sponsored long-haul computer networks like ARPANET, MILNET, SATNET and NSFNET, and perhaps even a private corporate or academic computer network or two. All of this complexity will have to be hidden from the end-users of the network; they will be far too busy typing lists of names into laptops to be bothered with managing virtual circuits in Telenet. Running the network will be the responsibility of the software running in the backbone packet switches plus the human operators of those switches. This is an extremely ambitious goal, and I have no illusions about the work that would be required to build a complete network that could handle even a small fraction of the offered load in a major emergency. But I think it's something worth thinking about.

Karn) To: PACKET-RADIO@EDDIE.MIT.EDU Subject: Re: New Data Link Layer protocol time? Summary: new link protocols References: <8801181533.AA08932@decwrl.dec.com> I'm glad to see that I'm in some company when it comes to wanting to replace AX.25. An ARRL-sponsored meeting had been scheduled in northern Virginia a weekend ago to discuss both short-term compatible changes to the current AX.25 (AX.25 Version 2.x) plus initial long-term proposals for a new protocol, one that would necessarily be incompatible with the old. (This new protocol has the working title AX.25 V3.0?, but more about this later). However the meeting was snowed out, and a new date hasn't been set yet. One proposal (from the Radio Amateur Telecommunications Society in the northern New Jersey area) has already been floated. Others would be most welcome. What follow are my own comments and ideas, not to be confused with those of RATS (not that there's much chance of this happening! :-)) Before I start bashing AX.25, though, there is one thing I believe was done *right* in its design, and that was the addition of a datagram- style address layer to each packet. This avoided so many problems, and has worked so well in practice, that it's hard to remember that anyone ever proposed "dynamic addressing" link protocols seriously. (The really fun part about all this is that the Founding Fathers Of AX.25 were and still are firmly in the "virtual circuit" camp, and to this day they vehemently deny having contaminated AX.25 with any datagram-like principles :-) ). The main problem with AX.25 as it now stands, and the main reason for the work on a new protocol, is the hard limit on callsign length: 6 characters. This is not a problem for most amateurs, but those required to identify with suffixes (temporary and reciprocal licenses, etc) are stuck. Fixing this implies a complete redesign of the addressing sublayer. In the process, we might as well do the whole thing right, since it will be incompatible with the present protocol anyway. So here are some thoughts about how to design a new protocol from the ground up. 1. The boundary above the datagram (address) sub-layer should be more clearly defined. The C-bits in AX25L2V2 (for which I take full blame) are a gross and disgusting hack because they carry information that properly belongs in the LAPB control field, not the address field. (I confess to taking CCITT at its word when they called the byte ahead of the control byte the "address octet", even though X.25 runs on point-to-point links where link level addressing has no meaning. I was young and naive then, and I hereby throw myself on the mercy of the court. :-) ) 2. There should be a protocol identifier field between the address field and the control field so that protocols other than LAPB can be used. It sort of works now with the UI (unnumbered information) frame, but it's "unclean". This translates into wasted header space and messier function-call interfaces between the various layers (I know, I've implemented this stuff). 3. The use of "bit shifting" in the present address field is a classic example of blind subservience to "international standards". ("Why was it done?" "Because ISO said so.") It bought absolutely nothing in terms of compatibility with anything else, but it created a low but persistent irritation factor (double ascii displays on trace dumps, extra code, etc). Furthermore, the information carried by the low order bits (the length of the address field) could have been encoded in fewer bits by just putting it in a count field. This also saves the CPU from having to scan each byte to find the end of the address field, something that will become important at high speeds. 4. Along the same lines, store-and-forward digipeaters (which won't go away completely, no matter how much we would like them to) should make their mark on packets by incrementing a "pointer" field in the address header rather than by setting has-been-repeated bits scattered throughout. This is how it's done in IP source routing, and it's also a lot faster to process. 5. The protocol should be more streamlined for connectionless network traffic. (Except for COSI, every amateur network layer protocol at present is connectionless). One should not have to go through a "null" LAPB layer to run the link in connectionless mode; that was my reason for suggesting a protocol ID field directly after the address field. Even if a connection-oriented protocol like LAPB is used to provide link-level acknowledgements, it should allow data in connect-request packets. This would be much like the "fast select" feature found at the network layer in X.25. 6. Asynchronous framing should definitely be an option. HDLC is nice, and now that we have it we might as well use it, but it should not be the only way things can be done. SLIP-style framing plus a suitable checksum would work just fine at low speeds. (SLIP is already used on the asynch port between a host computer and a KISS TNC). 7. Last but not least, we must name the new protocol something other than "AX.25". This is a serious misnomer even for the present protocol, as it misleads people into assuming it to be a compatible subset of CCITT X.25 in the way BX.25 ("Bell X.25") is. It isn't, and we're likely to diverge even further as we learn just how different the needs of amateur packet radio are from the wants of landline common-carriers. Furthermore, because of its CCITT connotations, "AX.25" is often downright embarassing to those of us trying to establish the legitimacy of amateur packet radio to our non-amateur peers in the more progressive communications research organizations. :-) Comments?

Your local fire department does NOT have a ham radio problem - they have a COMMUNICATIONS problem. They don't care how you solve the problem as long as it is solved. If you don't solve, well, they'll go somewhere else ... Similarly, sometimes as part of our public service work we get asked to do a function that the FCC currently considers illegal for us to perform (particularly with respect to the fuzzy areas around "almost business" communications) and so we say we CAN NOT HELP THEM. But if we see ourselves as generic communications problem solvers, we can do much better and offer to use an alternate radio service. We can probably get some of these groups to pay the costs of *renting* business band radios. Or, certain larger groups might even purchase some of they're own for use at special events. (This includes land mobile, 154 MHz 1 w portables, GMRS, even 49 MHz short range HTs). Look for my article, "Emergency Communications: Is it legal?" later this year, probably in QST. If anybody's interested, I'll post it to the net. (By the way, the answer to "Is it legal?" is YES!).

To have a viable protocol, it is not necessary to be compatible with HDLC. I do, however, believe that it IS necessary to use something similar, and the easy availablity of HDLC chips makes it a good candidate. Just sending bytes (without stuffing) leads to problems detecting the start and end of packets. I have seriously thought of using byte counts like DDCMP, but I realized that some other sort of recovery mechanism is needed (DDCMP has one), because loss of a byte throws the byte count off and makes resynchronization very difficult. The best thing I have seen for sending characters without error is AMTOR. I think to avoid flags (and the resultant stuffing, bit or byte) something of that type is needed. Especially in a radio environment, I would expect some sort of checksum would be necessary. Because multiple stations may transmit simultaneously, and especially since not all may be able to hear all the others, you will get collisions, and a good detection method is necessary. The CRC-16 algorithm works well, and chips implement it, so again it is a good choice. I have long been of the opinion that in a packet network, ISO protocols have a place AT THE TWO ENDS. I am not convinced that ISO protocols work well within the network. When the layers build up, there is a tremendous amount of overhead. ISO protocols also are good for point to point links.

The text is as follows: "The GLB netlink 220 is a digital-signal-in, digital-signal-out radio designed for high-speed packet linking. It is designed to solve the problems of interfacing high-speed modems to conventional VHF FM transceivers. The Netlink 220 is directly compatible with the GLB PK2 TNC. It also works with TAPR TNC 2s and TNC 2 clones, although a few minor PC-board modifications must be made to those TNCs. DEsigned for simplex operation in the 220-225Mhz range, NETLINK 220 features a data rate of 19,200 bauds and 2 W RF output. Additional features include * oven-controlled crystal oscillators for high stability * PIN diode antenna switching for fast (3 ms) turnaround time * automatic receiver tracking for long-term drift compensation * 5 helical resonators in the receiver for good spurious signal rejection * TTL/CMOS compatible digital inputs and outputs * conservative design for longtime reliability * transmitter watchdog timer The netlink 220 requires 12-13.8 V dc at 1.2 A.

Yes, they're widespread in commercial equipment. Despite it being an ISO standard, I even like it. (I'm referring only to that part of HDLC you generally find in hardware, i.e., framing, bit stuffing and CRC, not the brain-damaged LAPB protocol usually implemented in software above it). Unfortunately HDLC chips are still not as cheap as ordinary asynchronous UARTS, so you don't find many as standard equipment on the kinds of cheap computers most hams have in their shacks. Hence the desirability of an alternate (co-standard) link level protocol based on asynchronous framing. > I doubt if appletalk is good for these problems either... I believe the relevant part of AppleTalk is the low-level channel access mechanism. Not being familiar with it I'll let Paul describe it in detail. I believe it involves the transmission of a "request to send" message before sending actual data, the idea being to confine collisions to the request-to-send messages, not the data packets.

Although faster amateur modems are coming, ARPA experience has shown that UHF packet radio links are often limited by multipath reflections to speeds of 400 kbps or less. It's not *that* hard to filter packets at such speeds in software (unless you use obsolete Z-80s or 6502s :-)) I suppose we could compute a one-byte hash function over the destination address, putting this code at the start of the frame. The Vancouver "V2" protocol did something like this, but it omitted the regular source/destination callsign information. This got it banned in Australia, whose Department of Communications has mandated datagram- style headers containing full source and destination addressing at both the link and network layers in amateur packet radio. As long as the regular addressing is included, though, there's no problem in adding additional info. > , and a Packet-Type octet to select > interpretation of the remaining octets (to support different link-level > protocols, e.g., bootstrap, debugging, etc.). There is already a "level 3 Protocol ID" field in the present AX.25. I assume you mean that the implementation should be cleaner, e.g., to avoid the need for a "null LAPB layer" in the form of the UI frame. Agreed. > 2) A separate header checksum (and two flag bits, Allow-Damage and Damaged), > to permit FEC and/or transmission of data for which errors are acceptable. > (The header checksum would cover link and net level addresses and flags. > The Allow-Damage bit, when set, would indicate that the packet should be > processed, and any data forwarded as long as the header checksum was > valid.

This is very difficult in the context of a half-duplex channel, perhaps impossible when HDLC is used.

My question is; Are the gentlemen who are designing these schemes interested in worldwide compatibility? The reason I ask is that the packet network is, or will become, world-wide. If, at this early stage, the addressing schemes have North American dependencies built in, the only way that US Amateurs will be able to communicate with amateurs outside North America is through gateways or by special addressing schemes. It would seem that this is a plus point in favour of TCP/IP which appears not to have been mentioned so far - which although a US 'invention' is at least not dependent on cultural peculiarities such as ZIP codes, etc. (FYI, There is no European 'ZIP' code scheme. The British scheme uses a mixture of letters and numbers, for example my Postcode is AL3 5HP, (complete with a space). Postcodes are always 2 letters, a number, a space, a number and 2 letters. British telephone 'area codes' are not fixed length, so they can't be used either - although my 'area code ' (called STD codes in Britain) is 727, I have friends (looks in telephone book) with STD codes like 6285, 24020 and 1.)

So in the ham radio world, at least every ham who wants one, gets an IP address, maybe ALL of them, and somewhere there will be a complete mapping table. > NOTHING ELSE!

Unique yes, but the hierarchy is the IMPORTANT part because without its concept, you can have nothing but the totally impractical 1:1 mapping of half a million call signs. > The internet addresses are interpreted by the underlying transport > system to provide the routing.

It has to be done somehow, and there are choices in the ways to do it. I have to at least know what those choices are at the minimum. I would even like to get involved in the decisions if it would help (and I think it might). > When I connect using regular AX.25 packet rtty on 28.105 to VK2ALS, I > don't know, and don't need to know, whether he's in Australia or > Wisconsin.

You MIGHT connect directly, where your radio signal would actually reach his receiver, and visa-versa. Of course that would not involve routing, only recognition. But routing is a totally different matter. The best way to consider routing is to think of working on UHF. > How is this done?

Just as with the USPS's ability to Ah ha... you are now FINALLY getting to what I actually asked. So, his IP address changes when he MOVES is PRIMARY STATION. Now what about PORTABLE OPERATION at my parents home, at my brother's home, at my other brother's home, at my vacation retreat, at a DX-pedition, what about the home of the girl I just met last week who lives 500 miles away and I am going to go visit her there and operate portable. The experiences of a national TCP/IP network are things we need to know, but can cannot consider that this is all that we need to know. Ham Radio poses many NEW problems. We need to consider them. They do NOT have to be considered immediately to get a TCP/IP network going at a minimum, but we will eventually HAVE TO be considered, and the optimal solutions there MIGHT be incompatible (in terms of all those AUTOMAGICAL things going on) with what is designed first. We need to consider all things now, so that we can get a good network going sooner, without all the problems of compatibilities. Maybe someone has already considered it; maybe they already have a working solution; maybe even YOU have done it; but its is NOT out on the table for those who care to see. > cope with forwarding your mail when you move, the IP network can > redirect an address too - so that you could conceivable keep your IP > address when you move.

I don't think addressing a problem with "USER NEVER SEES THIS" is going to help make it work better. I fully agree that the user should not HAVE TO see it, but I also want to make sure that it REALLY works under the unique problems that Ham Radio pose. If it FAILS, then the user won't see that either?????? > I hope this makes it a bit clearer.

It didn't get here by Ham Radio. It didn't get here by having every single node be known by every other node. It didn't get by a direct connection on an Ethernet. It didn't get here AUTOMAGICALLY. 30-Jan-88 15:58:36-EST,1068;000000000000 Received: from EDDIE.MIT.EDU by DEEP-THOUGHT.MIT.EDU via Chaosnet; 30 Jan 88 15:58-EST Received: by EDDIE.MIT.EDU with sendmail-5.45/4.7 id <AA23714@EDDIE.MIT.EDU>; Sat, 30 Jan 88 15:08:47 EST Received: by EDDIE.MIT.EDU with sendmail-5.45/4.7 id <AA23701@EDDIE.MIT.EDU>; Sat, 30 Jan 88 15:08:21 EST Received: by june.cs.washington.edu (5.52.1/6.11) id AA22460; Sat, 30 Jan 88 12:08:25 PST Date: Sat, 30 Jan 88 12:08:25 PST From: bcn@june.cs.washington.edu (Clifford Neuman) Return-Path: <bcn@june.cs.washington.edu> Message-Id: <8801302008.AA22460@june.cs.washington.edu> To: JLULEJIAN%HMCVAX.BITNET@MITVMA.MIT.EDU Cc: packet-radio@eddie.MIT.EDU In-Reply-To: Death to the Daleks!'s message of Thu, 17 Sep 87 09:26 PDT <8709171644.AA05373@EDDIE.MIT.EDU> Subject: Mailing List Removal Have you been removed from the packet radio mailing list as per your request.
