871225.33.PE1CHL.900813: Fixed minor bugs in Turbo C version for the PC. SCC driver now allows complete specification of the clocking mode, so that all modems requiring- or providing external clocks can now be controlled. The value to be written to WR11 of the Z8530 can now be specified as a hexadecimal value after the existing baudrate specification, separated by a colon (e.g. d1200:66). This is not necessary for the standard AFSK modems and the HAPN 4800 baud modem, as these do not require external clocks. Refer to a Z8530 technical manual for more information about the value to be written to WR11. 871225.33.PE1CHL.900807: Fixed a problem in the AX.25 forwarder: when no "r" or "w" line was present in the script after "m" "u" or "b", the forwarder did not proceed. Therefore it was impossible to forward to mailboxes that do not prompt for the subject and/or the message, or don't send a CR after such prompts. This is now fixed, and the following script works: # forward test to personal mailbox c 430 pe1chl-15 w> # now we are connected, send each mail l mS%.0s %s u%s b rOK w> n This sends the S <call> command, the subject, and the entire message in one go, and then checks for a response containing "OK". For more detail about forwarding scripts see the explanation further down this file. The forwarder now concatenates multiple lines from the message into a single packet, whenever the total length of these lines is below paclen, except when the effective window (maxframe) is less than 2. The answer to a often-asked question about NET/ROM: You can use different calls for the NET/ROM on different interfaces (e.g. a PI1 call on 23cm). Specify the calls you want to use in the "attach" commands for the different interfaces. Somewhere after these attach commands the autoexec.net file contains the line "attach netrom $CALLSIGN-9". When this line is changed to "attach netrom" (without the callsign), the NET/ROM will use the interface callsigns on each band. Make sure that you use a "hidden" alias (starting with a # sign) for the interlink nodes of the NET/ROM! The alias can be separately specified for each interface in the "netrom interface" lines. 871225.33.PE1CHL.900710: On "exit", the program now waits for the interface queues to drain. This should solve problems with param commands placed in "onexit.net". This often did not function reliably because the interfaces were reset *before* the characters were actually transmitted. Atari version now supports up to 5 async channels. The 2 params after "attach asy" (<addr> and <vec>) can now have the following values: addr vec 1 0 ST RS232 port using Bcon* calls (BIOS) 1 1 ST RS232 port using direct access to fifo buffer 3 0 MIDI port 6 0 ST-compatible RS232 port on TT030 7 0 MODEM2 port on TT030 8 0 SERIAL1 port on TT030 9 0 SERIAL2 port on TT030 The old <addr> values 0 and 2 remain valid (for RS232 and MIDI). Ports 6 and 7 could also be used on an ST with TOS 1.2 or higher, and a user- written device driver (loaded from the AUTO folder) that supports the Bcon* routines on BIOS devices 6 and 7. However, on an ST it is not possible to set the mode and baudrate for these channels so your driver must set the port to 8bit, no parity, 1 stopbit, no handshake and the correct baudrate. The driver must also supply a FIFO buffer for transmit and receive. Unix/XENIX release. Only supports async I/O for now... (SLIP/KISS/NRS) To attach a serial line, use an attach command like this: attach asy /dev/tty1a 0 ax25 ax0 512 256 9600 pe1chl - the tty device (/dev/tty1a) must be "disable"d, and have read/write permission for the user running NET. - the "0" value can be replaced by "r", "c" or "rc" to set the RTSFLOW and CTSFLOW options for the device. - the next two fields are the type (ax25) and name (ax0) - the "512" is the size of the read() buffer used for receive - the "256" is the MTU (paclen) - the next fields are the speed (bits per second) and callsign The program is available in 2 versions, net286 and net386. The '386 version can use the select() function internally to improve efficiency. This can be enabled by starting the program using: net386 select=kt The 'k' and 't' enable the use of select() for keyboard(stdin) and tty devices. It is also possible to set an environment variable SELECT to this value. Testing using SCO XENIX386 release 2.3.2 has shown that the select() function somehow clobbers the tty input and output buffers, so the use of this option is not yet recommended. The "dos" commands CD, COPY, TYPE, RENAME etc. are not implemented. Use a subshell or a different window to perform these functions (except CD). Incoming mail is stored in the /usr/spool/mail directory (or to the directory defined by the NETMAILS). This directory must be writable by the user running NET to be able to receive mail. The standard mailer can read the incoming mail, but I do not yet know how to prepare outgoing mail. Mail stored in the directory /usr/spool/mqueue (NETMAILQ), using the same format as in the DOS version of NET, is transmitted by SMTP. This directory *must* exist and be writable for the user running NET. All configuration files are located in the "current directory" as effective when the program is started. It is recommended to create a user "net", and to put the configuration files and the program in it's home directory. NET can then be started from the .profile, so that logging in as "net" is sufficient. The FINGER files are stored in a subdirectory "finger", *without* the .txt extension used by the DOS version of NET. The TNC2 emulator will be implemented in a future release (using a FIFO). 871225.33.PE1CHL.900623: Fixed problem that caused crash when an excluded station was connected from the NET/ROM. Many users complain about problems with IP and/or selected AX.25 servers. Please note, that in this software each AX.25 server (defined using "ax25 port") *must* have a *different* SSID, and that each interface (defined using "attach") *must* have an SSID *different* from all SSID's used by AX.25 servers. Different interfaces may use the same SSID, but cross-band digipeating will not be possible in that case. The autoexec.net file provided as an example follows these rules, but many people have modified the SSID's and subsequently had strange problems... When you use the -0 SSID for an interface, the TNC server *must* have some other SSID, or IP will not work. To avoid problems, everybody is hereby encouraged to use the following SSID scheme (proposed by PE1LGT): SSID Interf Function -0 All TNC (normal ax.25 connect) -1 All MBOX -2 144 2m interface -3 144 mheard/NetDigi 2m -4 4k8 2m/4800 baud interface -5 4k8 mheard/NetDigi 2m/4800 baud -6 All Conference Bridge -7 430 70cm interface -8 430 mheard/NetDigi 70cm -9 All NET/ROM -10 aaaa interface -11 aaaa mheard/NetDigi -12 23cm 23cm interface -13 23cm mheard/NetDigi 23cm -14 bbbb interface -15 bbbb mheard/NetDigi aaaa en bbbb usable for other bands, e.g. 28 or 50 MHz avoid using the -14 and -15 SSID's on bands where a local NET/ROM is operating. 871225.33.PE1CHL.900611: Atari version: moved disable/restore handler to trap #7, to allow the use of trap #5 as a micro_rtx system call. This is only possible for MWC release 3.0.0 and above. No testing done with micro_rtx. Fixed protocol problem that caused AX.25 failures when connected to G8BPQ nodes. Some changes made to improve portability. Attempt made to run under XENIX. (it compiles okay, but the async port handling still causes headaches) 871225.33.PE1CHL.900530: TZ or TIMEZONE (depending on machine+compiler) environment variable now gets a default value GMT0 when it has not been set by the user. This prevents funny behaviour when "at" is used (default was Pacific Standard Time). You can still set your own preferred timezone. Automatic ticks/second and "at" command removed from Aztec version. The library function time() returns an unusable value, and the Aztec version reported an incorrect value of 36 ticks/s because of this. 871225.33.PE1CHL.900522: Fixed problem in SMTP that sometimes caused the program to crash (when mails containing very long lines were received) Also, built extra test in watchdog so that "watchdog ?" no longer causes the PC to crash. Now, specification of 0 or a non-numerical port number also disables the watchdog (instead of clobbering port 0, the DMA controller). Of course, this still leaves plenty of opportunities to scramble the system through specification of weird port numbers. Be careful! 871225.33.PE1CHL.900520: Fixed problem in NET/ROM level 4. Sometimes the transport-level timeout timer did not run while frames were outstanding, causing connection failures under certain circumstances. 871225.33.PE1CHL.900519: "watchdog" command now also installed in PC version. It can only drive an external watchdog timer. The syntax of the watchdog command is: watchdog [<port> <value>] When specified, the <port> and <value> select the output port to be used for the watchdog. The value is OR-ed to the value read (input) from the port, and this value is output to the port. Some time later the value is complemented and AND-ed to the port value. The result should be that one or more output bits toggle at each pass through the main loop. The watchdog triggering can be stopped by specification of a zero <value>. 871225.33.PE1CHL.900513: New command "tcp active" shows only those TCP sessions that are not in the "Listen (S)" state. This gives a shorter list, especially when many servers are started. Fixed "from" address in AX.25 mailbox (to provide proper returnpath for errors) Small changes in SMTPCLI to make it more RFC821-compatible 871225.33.PE1CHL.900506: Fixed problem in NET/ROM: when multiple NET/ROM level 4 packets were received, some with the MORE bit set, and the total length of info was over 256, the AX.25 link transmitted packets over 256 bytes in length. Now these are split in multiple packets each up to 256 bytes in length. 871225.33.PE1CHL.900503: Improved NET/ROM handling of failing routes. When a NET/ROM broadcast is sent, nodes with only 0-quality routes are broadcast too (with that 0 quality). When such a broadcast is received, the particular route is deleted. Corrected TNC2 emulator message at disconnect. Must not print callsign. Improved the FRAMESAMMLER. Now, the functionality is the same as the Digicom and RMNC implementations. It should now be safe to set "ax25 maxsammler 7", independent of the other station's maxframe. New command: netrom users Displays the local NET/ROM users, just like the "users" command when connected to the NET/ROM. Atari version only: added "log proc" command, to dump the processor exception area to the logfile, when it contains a valid exception (bombs) dump. When this command is inserted after the "log <filename>" command in autoexec.net, information about a preceeding crash is put in the logfile. The format is: Sun Apr 29 15:54:00 1990 exception dump (BP=0005F126) 00000000 00000020 000023ED 00000020 00000013 00000000 00000001 00000001 0004E71B 00020284 00000000 0004B5D8 00FDD1F4 00000000 00001804 000017BC 04FC0B12 000061A0 23080000 180800FC 9DA20000 000A0000 5F360000 03100000 00460000 000000FE The BP value is the current basepage address. This could be the same as the basepage address at the time of the exception, but this is uncertain. The following lines are a dump of the area at 0x384, see an Atari internals manual for more detail. This command is only intended for software debugging and/or bug reporting, when you don't understand it's purpose, you do not need to use it! Adapted some source modules for compilation using Turbo C 2.0 on the PC. Solved problem in NET/ROM causing crash when user aborts pending connection. Added "uplink" option to "netrom interface" command (see below), and made netrom level 4 configurable. just set the "netrom param 4" parameters to 0 to disable net/rom level 4. then, the node will always return "busy" when connected from another net/rom node, and node connects from the net/rom always fail. 871225.33.PE1CHL.900415: NET/ROM (level 4 & 7) support completed. It is now possible to connect other nodes, and to list the connected users. New NET/ROM commands: INFO (replaces IDENT) Show information about the NET/ROM MHEARD [<interface>] Show the MHEARD list PORTS [<interface>] List available NET/ROM ports (interfaces) and optionally selects the interface to be used for downlink connects. When a CONNECT to an AX.25 station is made, an interface is selected: - For AX.25 connected stations: the interface they are connected on - For NET/ROM connected stations: the default (LAP) interface The interface can be changed by a "port <interface>" command before the CONNECT. New ("net>" prompt) commands are: netrom info <filename> sets the name of the file to be sent after the normal response to the "INFO" NET/ROM cmd. It can be used to send a station description. Keep this file small!! The length should not exceed 1 kilobyte! netrom interface <iface> <alias> <quality> [lap|uplink] the extra option "lap" must be given on only ONE of the "netrom interface" lines to specify the default interface for downlink AX.25 connects. (Local Access Point). the option "uplink" can be given on other lines, to specify that user-uplinks are allowed on that particular interface. when neither "uplink" nor "lap" are given, the netrom will not process commands when connected. 871225.33.PE1CHL.900325: Again changed the behaviour when REJ is received - probably a conversion to the newer AX.25 code would be a better idea... Added an interrupt-latency measurement routine to Atari version, to evaluate the effects of some efficiency improvements. This is not intended to be a feature useful to the end-user. The "latency" command is used to switch this feature on- and off, and to display the results. 871225.33.PE1CHL.900314: Added capability to write (or append) incoming mail to a specified file. This can be used to keep a file in the public area uptodate using a mailing list. (e.g. hostsfiles, tcp-group mail) When the first line of a "mailbox" file (mail\xxxx.txt) is of the form: write c:\net\public\hosts.137 or: append c:\net\public\tcpgroup the incoming mail will be written (or appended) to the specified file, not to the mailbox file. When a suitable "alias" file entry is made, it is possible to write the mail both to a file and to a mailbox. Incoming mail is now marked with the source (when "new mail arrived" is printed on the console) 871225.33.PE1CHL.900304: Added a second parameter to "smtp timer": the time to be used when a mail needs to be forwarded. Whenever a mail arrives that has to be forwarded the "smtp timer" will be set to this value and re-started. This allows a long time between polls of the mailqueue, while still forwarding mail within reasonable time. This parameter should not be set too low, to allow more than one mail to be queued and the SMTP session to be terminated before the forwarding is started. Recommended value is 500 seconds. The main timer can now be set to slightly more than one hour, to set the time between attempts of the AX.25 BBS forwarding. Exactly one hour is not recommended because this could synchronize the attempts with normal inter-BBS forwarding. 4000 seconds is a good value. (smtp timer 4000 500) 871225.33.PE1CHL.900303: HOME and END (Atari: Ctrl-Home) keys now move the cursor to the beginning and end of the input line, respectively. Fixed SCC speed-setting using "param" for Atari ST (it crashed the program) Corrected TCP windowsize for ascii-mode transfer of FTP, and SMTP. 871225.33.PE1CHL.900211: Added forwarding from NET to RLI/MBL-style mailboxes and personal maildrops. This is kind of a hack, as several conversions have to be made on SMTP mail addresses and headers. The feature operates as follows: When mail must be sent to a host, a check is made if the hostname is of the form <call>.bbs, and if a file exists in the MQUEUE directory with this name. If both of these conditions are met, the mail is forwarded using a script in the MQUEUE\<call>.bbs file. The script contains lines, of which the first character is an opcode: # this line is a comment c only as the first line: specifies the initial connect to be made. this can be a connect to the bbs, or to a NET/ROM node that is used to reach the bbs. syntax is like the net> connect command. s send string to remote BBS or node. can be used to send strings containing connect commands to NET/ROM nodes. w wait for specified string to be received. lines not containing this string are ignored. useful during connect and disconnect phase, to eat banners sent by the BBS. r checks for a specified string to be received. when a line not containing this string is received in the message transfer phase, it is mailed back to the message sender (it probably is an error) while in the connect phase, the box is simply disconnected. l marks the point in the script where the connect ends, and the messages are transferred. ("loop") m defines the line to be sent to send a message. line is used as an argument to sprintf, with the following string args: 1. message type ("P") 2. destination call 3. destination bbs 4. source call 5. message id u send subject of message. line is an argument to sprintf, with the message subject as an argument. b send the body of the message. any text after the "b" is sent as the end-of-message marker. the default is ^Z. n defines the end of the message transfer lines and the start of the disconnect phase. control will branch back to "l" when more messages are to be sent ("next") Examples: to directly connect to a BBS (AA4RE-type): # forward to PA3APN c 650 pa3apn w==> # now we are connected, send each mail l mS%s %s@%s < %.6s $%.12s rBetreft u%s rBericht b ropgeslagen w==> n # all done, send "bye" command sB w73 To connect to a BBS via NET/ROM: # forward to PI8EAE via PI8RNI-7 NET/ROM c 430 pi8rni-7 sc pi8eae rConnected to w} # now we are connected, send each mail l mS%s %s @ %s < %.6s $%.12s rSubject u%s rmessage b r} n Another NET/ROM example: # forward to PI8ABT via PI8RNI-7/PI8ABT-7 NET/ROM c 430 pi8rni-7 sc zbl70 rConnected to sc pi8abt rConnected to w> # now we are connected, send each mail l mS%s %s@%s < %.6s $%.12s rOmschrijving u%s rBericht b ropgeslagen w> n As can be seen, the scripts must be tuned to match the exact responses sent by the local BBS, such as the "subject" and "message" prompts, and the final character of the BBS prompt (">" or "}"). It is possible to write scripts that ignore the prompts (just omit the "r" lines and put only a "w>" or "w}" after the body) but this will kill the error checking capabilities of the forwarder. Remember that NET/ROM will cancel a connection when you send something without waiting. Always include an "rConnected" line after a NET/ROM connect command. Added support for "Type of Service" as offered by TCP. TOS is composed of characters 0-7,D,T,R for precedence, low delay, high throughput, high reliability. Low-delay will force UI frames to be used, High-reliability will force connected mode, both overriding the selected default mode (using "mode" command). Other TOS selections may be effective for particular IP implementations and/or subnetworks, but are currently not acted upon by NET. With "telnet" and "ftp" and "start", specify TOS using a 3rd/4th parameter. Otherwise set/change the TOS using the "tcp tos <tcb> <tos>" command. You cannot change the precedence of an existing connection. 871225.33.PE1CHL.900123: Atari ST: Now, tempfiles are deleted immediately after use. netrom exclude <nodecall> [d]: excludes certain nodes from the nodelist. The "d" option removes a call from the exclude list. This can be used when it is known that a node has it's parameters set up in such a way that a connect will not be possible because a retour route can not be established. (so-called "Belgian parameters") 871225.33.PE1CHL.900113: Swapped Rcv-Q and Snd-Q in ax25 status output to make it consistent with other status listings (session, tcp status) Fixed an error in sccvec.asm, that caused malfunction in large model on PCs. Atari ST: Now compiled it using MWC 3.0.9 instead of 2.1.7. A savings of 1.9% in code size! 871225.33.PE1CHL.900109: Fixed problem in FTP client causing a crash when the user typed "type l". This caused a BUS ERROR because "type l" needs an extra argument and a NULL pointer was dereferenced when this argument wasn't supplied (attd by SM0IES) 871225.33.PE1CHL.900107: Added support for the DRSI PC*Packet adapter in the SCC driver. (hardwaretype = 08) Added support for external transmit/receive clocks in the SCC driver. Use "ext" instead of the baudrate to get RTxC=RX clock, TRxC=TX clock. With the SCC driver in AX.25 mode, a new speed can now be set using "param <iface> speed <speed>". This only works when internal clocking was specified during init, and it cannot switch between internal and external clocking. In AX.25 mode, the transmitter can be disabled using "param <iface> tx n". This is useful for unattended stations (when interference reports have been received by the control operator he can issue this command via rcmd). ARP entries added to the table as a result of ARP packets received will now be marked with the interface of their origin. It is no longer assumed that an address received on some interface is also valid on another. Interfaces may be specified in arp add, drop and publish commands using the syntax "<type>:<interface>". e.g. arp add pe1chl ax25:144 pe1chl-2 This was primarily done to solve the problems that occur when 4800 baud and 1200 baud modems are used in parallel on the same frequency. Now it is no longer necessary to enter fixed ARP entries for 4800 baud. The selected method of specification of the interface keeps the "arp" command compatible with earlier releases of the program. Added the W9NK TCP/IP mailbox. This is an AX.25 server that allows AX.25 stations to send SMTP mail to the owner of the box and to other TCP/IP stations to which the box owner can forward SMTP mail. The mailbox accepts forwarding from the de-facto standard BBS systems. To use the mailbox, initialize AX.25 port #6, and start the ax25 mbox server: ax25 port 6 conn pe1chl-1 ax25 start mbox \net\finger\rob.txt The (optional) filename specified after the start command specifies the "info" file for your box, sent to the connected user when he types an "i". Incoming mail is only routed (to the local user or to others) when the SMTP timer ticks. You'll have to set your "smtp timer" to a reasonable time to receive your mail without long delays (say, up to 7200 seconds). Added support for multi-channel KISS TNCs. These boxes encode the radio channel number in the upper nibble of the KISS type byte. To use this feature: Attach the physical device using "attach asy" or "attach com", as before. The channel number zero will be accessed using the defined parameters. To access channels 1 to 15, use: attach kiss <parent> <channel> <label> <mtu> <call> The <parent> is the physical interface attached before. <channel> is the channel number used by the TNC (1..15). e.g.: attach kiss ax0 1 ax1 256 pe1chl-7 This will make the second channel of the KISS TNC available as "ax1", with a maximum IP packet length of 256 and a callsign "pe1chl-7". Modified "copy" to allow device specs in Atari version. Hope it does not break down on other versions. 871225.33.PE1CHL.891225: Added "x" option to "tput" FTP subcommand to update attributes of a file after it has been sent. This ensures the file will have the same date/time and "read only" status on the destination after a transfer. This is implemented using an "XATR" FTP command that is sent after each "STOR", containing this information in an MSDOS specific format. For now, this is only implemented in the Atari ST version. Also made response on "MKD" according to RFC959. "at" command corrected, now it always uses the local time. Added "netrom route drop * <iface> <neighbor>", to drop all NET/ROM routes via specified neighbor (e.g. when you know it has been taken out of service). This only affects non-permanent routes. Added NET/ROM level 3 parameter "maxqueue", specifying the maximum number of AX.25 packets allowed on an outgoing AX.25 queue. Any packets that have to be queued above this limit are dropped, and an alternative route to this destination is chosen, if possible. Added NET/ROM level 3 parameter "maxfail". When more than this number of link failures occurs on an AX.25 link to a neigbor, all non-permanent routes via this neighbor are dropped (until we next hear a broadcast from him). This should limit the forever-retrying on dead links (dead nodes). Set "maxfail" to zero to disable this feature. 871225.33.PE1CHL.891217: Added "tput" FTP subcommand to put a (sub)tree. Before using it, the target directory must be set using "cd", and the file type (usually I) to be used for all the transfers should be selected. Then, a "tput <dirname>" or a "tput <wildcard spec>" will start automatic creation of subdirectories and transfer of files. The session should remain selected to allow display of messages and execution of further commands. Use "abort" to terminate the process. DON'T change the local "current directory" when an incomplete pathname was specified for the "tput". Solved some problems with pathnames specifying a drivename and/or the "." notation for current directory. Implemented "netrom tcpip interlink" to let the NET/ROM pass only visible nodes and #TCPIP. (#others are not broadcast, but appear in the nodelist) This is similar to the "TheNet I-version", but without the disadvantage of inhibiting TCP/IP traffic. When "netrom nodefilter exclusive" mode is selected, this provides very good control over the number of nodes in the broadcast and the NET/ROM traffic through the node. Added extra delays in the SCC driver (MSDOS version only) to allow it to run on very fast machines. 871225.33.PE1CHL.891209: NET/ROM nodefilter mode "exclusive" added. Works like "accept", but additionally no NET/ROM transport packets are accepted from stations not listed. Only stations in the "netrom nodefilter" list are accepted for NET/ROM traffic. A NET/ROM retour route is now also created when only 0-quality routes exist to the sender (this was only done when no routes existed). Experimental NET/ROM level 4 code added. Accepts connects from other NET/ROM stations but cannot connect to others. "netrom status" lists the current connections. Changed "isdir" to fix a problem with the MSDOS/MSC version (it said that a device was a directory, so "copy file prn" would fail) Made configuration depending on memory model and compiler, to ease maintenance and prevent distribution of unworkable versions (like MEDIUM MODEL with lots of memory-demanding functions) 871225.33.PE1CHL.891031: Atari version: memstat <number> mallocs and frees the specified number of bytes, to get these from the OS in one big chunk. Old versions of the system have trouble with programs making a lot of allocation requests, and the Mark Williams C runtime makes requests in small (2K) units. Putting "memstat 30000" or so at the beginning of autoexec.net will acquire some memory to start with. The <number> is a long integer. Fixed problem in netrom route handling that caused inconsistency (and hangup) when memory could not be allocated to store received routes (see above). Fixed broken "dir" command (wouldn't list directories after "improvement") 871225.33.PE1CHL.891001: route info <ip addr> command will print the IP route to another host improved handling of directories in DIRUTIL.C (because of TurboC problems) 871225.33.PE1CHL.890924: Greatly improved error handling in SMTP server (disk full, out of mem) Also introduced timeout in server (waiting on commands) Introduced "at" command to run NET command at certain time-of-day. Syntax is: at hh:mm command [params] example: at 18:00 stop ftp "at" command without params prints a list of scheduled commands. Only one command can be started at each time. Use "source" command to start a sequence of commands. (stored in a file) stopping FTP/SMTP/RCMD servers does not produce a log message anymore improved handling of AX.25 excluded calls. these cannot be connected anymore, also from bridge, netdigi etc. 871225.33.PE1CHL.890918: Minor change to make NET/ROM "param" command output compatible with NET/ROM. (some programs interpret this output for a better display) Fixed problem with timeouts in SMTP client (it failed when a mail took more than "tcp timeout" time to transfer) Log now flushed every time, log without params doesn't flush anymore Added watchdog timer (called from timer interrupt, reset from main loop). The "watchdog" command sets timeout values (in seconds) for 2 cases: the first value is used while in NET, the second when executing a SHELL. When a 3rd arg is given, it's (HEX) value will be put out on bit 0 of the printer port every time the watchdog is reset, followed by a zero value. This can be used to trigger an external (hardware) watchdog timer. This should not affect printer operation, as no strobe pulse is sent, only a change on the datalines. (for now, watchdog functions are only present in the Atari version) Solved problems with "*" and "?" in filenames in ftpserver 871225.33.PE1CHL.890910: Made a lot of small changes to compile the package with Turbo C on the Atari. (Mainly suspicious constructs warned by Turbo C, and MW C dependencies) It does not yet work correctly when compiled with Turbo C. Introduced "onexit.net" file, executed during "exit", just after all connections are closed. Can be used to send param 255's or copy files. Added an extra check in the Atari SCC driver to detect a permanently-low IRQ line from the SCCs. 871225.33.PE1CHL.890825: Yet another dup_p replaced by copy_p: the SCC driver transmitted garbage when an AX.25 packet was acknowledged when a retry was already sitting in the SCC transmit queue... (this could also happen with KISS, but it is less likely). Now, in lapb_output() a packet is copied to a new buffer instead of dup'd. (same in recover()) 871225.33.PE1CHL.890814: Fixed the last (?) flow-control problem in the NetDigi (and possibly other AX25 services driven by the transmit upcall). It now only asks for as many bytes as will fit in the maxframe window. This is the "final PC release" distributed in Aztec, MSC Middle and MSC Large. 871225.33.PE1CHL.890812: Corrected a problem introduced in the router in 890809 (only /32 and default work), and made the router cache more effective. PC: Fixed bugs in the SCC interrupt handler. This also affected the handler for the 3c500 in the Aztec version of 890812. "date" command now can set the date and time in MSC-compiled versions for the PC. 871225.33.PE1CHL.890809: Finally tracked down a problem with ctime(), which only appeared using MSC. It loses it's terminating \n under some circumstances, which caused funny results in smtp. Added yet more checks for NULL pointers (from malloc). Now prints "No Space!!" when no buffer is available for a ping (with length >0). This can cause mesages when a repeated ping is set up. Now I know how TCP sessions could stay in CLOSED state. Fixed FTP state change upcall handler, so that it should not happen anymore. MSC-compiled version (without PACKET and 3C500 drivers) can now be compiled in LARGE model on the PC. This should solve the problems of running out of heap space, at least when you have enough free memory in the machine (or section or window). This version is about 30% bigger and slower than the standard MIDDLE model version. 871225.33.PE1CHL.890731: Set a timeout on CLOSED state (TCP). A session was left in this state after an FTP (directory) with all timers stopped, but I don't know how it happened. Changed appearance of NET/ROM "param" command output to be compatible with NET/ROM 1.2 871225.33.PE1CHL.890725: Converted all .asm files to pmacros.h usage. Should be usable with MSC, TC and Aztec. NETROM4 define introduced to omit all NET/ROM level 4 support. Changes to pc.c, dirutil.c to make it run under MSC 5.1 Fixed trouble with receiving from Fossil (again) 871225.33.PE1CHL.890722: Fixed problem with hostname translation in 870720. It was only printed in the incoming session message, not in the session display. Also scanned all sources for occurrence of inet_ntoa and psocket, and fixed declarations. Fixed silly bug introduced in 890720 (resolve did not work on PC) PC version: Fixed problem with TNC2 emulation on COM port (device number off-by-one) PC version: Fixed hardware handshake problem for KISS tnc's (again...) TNC2 emulator can now XON/XOFF when FOSSIL driver is used Fixed problem in FTP login sequence (attd by dg2kk) 871225.33.PE1CHL.890720: All versions: Included an ip_address-to-hostname translator supplied by pe1jlj (after some modification). Incoming telnet sessions are now labeled with the hostname instead of the IP address. All versions: Added -f flag to "delete", "rmdir" and "mkdir" commands, to make these silent in case errors occur. Useful to clearout temp directories and lockfiles from AUTOEXEC.NET, without getting complaints about the non-existence of these files. Use it like "del -f ${NETMAILQ}*.lck". SCC driver: When DCD is active during initialization of the driver, the receiver is enabled immediately. This used to happen only on inactive-to-active transitions of DCD. (Added after request from pa0hzp who was testing his board) NET/ROM: When a NODES broadcast comes in which contains routes to a certain destination with a better quality than the currently active route, that better route is again selected, even when it was dropped before because of a link failure. This is done to prevent infinite re-routing of NET/ROM links in case of a temporary link problem (there used to be no mechanism to re-select a dropped route...). When the station receives NODES broadcasts from distant nodes regularly, these nodes should be filtered out to prevent repeated tries of the direct links to these nodes. PC version: Added "date" command. Prints or sets the system date and time. date setting does not work yet. PC version: Included the possibility to emulate a TNC2 on an external COM port. Algorithm is now as follows: when COM1-COM6 is specified in the "ax25 start tnc2" the code checks for the presence of an INT14 handler for that port. If it finds one, it will start the emulator on that external port. MBBIOS or FOSSIL should be loaded for the selected port. (the standard BIOS handler will lose big time!!! no interrupt handling in the ROM BIOS...) The baudrate of the external port is fixed to 9600 (8 bits, no parity, 1 stop). When a port above 6 is used, or there is no INT14 handler present, the code continues to use the "virtual COM port" accessible from the other doubledos section to emulate the TNC. NOTE: All this only works in versions compiled to support COMBIOS/MBBIOS/FOSSIL instead of the built-in "asy" device. PC version: timeout on transmit character emulation routine (virtual COM port) increased from 5 to 25 seconds, to allow for very bad AX.25 links to a BBS running on TNC2 emulation. The WA7MBL bbs does not test for timeouts, and therefore drops characters when one occurs. Attempted to make slightly more heap space available to those poor PC users, by putting more common text strings in variables (so that they appear in the 64K datasegment only once). Now 31552 bytes of heap, hooray. There is still more than 16K of fixed text in the data segment... 871225.33.PE1CHL.890622: additions: ping length [<value>] default <value> is 0 defines the number of extra bytes to be send with each ICMP echo reply. useful for testing path and modem quality. maximum value <value> is 4095 ax25 maxsamml [<no# frames>] default <no# frames> is 0 A framesammler algorithm has been implemented. Non-sequential receiving of frames on AX.25 connections is possible now. This option is disabled when <no# frames> is 0 100 % data integrity is only guaranteed when using this option with a <no# frames> value wich 4 or lower and if the other side has a Maxframe of 4 or lower. Atari version: added "screen" command, to select NET's method of screen output: screen bios use BIOS call Bconout screen direct use direct writes to screen memory (fastest) screen tos use standard output (default) "screen direct" only works on standard resolutions, not on "big screens". 871225.33.PE1CHL.890515: additions: new ax25 server: tnc2 emulator This server allows you to emulate a TNC2 running TAPR 1.1.6 code. This TNC2 can then be used by client programs running in the other section when using doubledos. (from the 890720 version it is also possible to connect the TNC2 emulator to an external COM port) This allows you to run a BBS concurrently with NET, using the same hardware (KISS tnc, SCC board or whatever) to interface to the radio(s). Also, other packet programs can be run this way, as long as they interface with the TNC using INT 14H (as is the case with MBBIOS, COMBIOS etc). The emulator tries to mimick the functional aspects of the TNC2 software as well as possible. Features not supported are: - setting of operational parameters like timing, async port settings etc - monitoring and it's associated parameters - calibration and testing - multiple streams (users) - battery backed-up RAM Most other features are supported, including CONVERSE and TRANS mode, input line editing, and even KISS. There is one extra command, not found in TNC2 software, that is introduced to compromise the efficiency of CPU usage with the requirements of the client program: KISSRX <number> This command selects which frames will be "received" by the emulator when it is running KISS mode (KISS ON, RESTART). This can be set using param 6 when KISS mode is already selected. The meaning of the number is: 0 receive nothing (transmit-only) 1 receive frames addressed to "MYCALL" only (the call of ax25 port 5) 2 receive all frames addressed to callsigns belonging to this station, and also to QST and NODES. 3 receive all frames that are already digipeated 4 receive everything To use the tnc2 emulator: Run NET under DoubleDOS. NET needs about 230K. Find the exact requirement by increasing the section size in small increments, until the free space printed by the "memstat" command immediately after startup does not increase any more. - define ax25 port 5 - start ax25 server "tnc" with parameter list. each parameter is of the form comnumber=interface. example: ax25 start tnc2 3=144 4=430 After starting NET, run "NETCOM" in the other partition, specifying the TNC port numbers (from above command). You can also specify the /b flag, which enables a buffer between the client program and NET. Some BBS programs don't like this, experiment with it. Example: netcom /b 3 4 Therafter, you can use "YAPPB", "WA7MBL BBS" etc in that partition, configured for COM3, COM4 etc. Do NOT use any of the real com ports (COM1, COM2). If you have more than 2 COM ports in the machine, use higher numbers. NET allows up to COM255, but the packages you want to run may be more limited. For first experiments, use YAPPB <com#>. Variables now supported in NET commands. see environ.txt for details FTP server has an extra feature: a lister for the contents of .ARC files. usage: (ftp subcommand!) dir <filename>.arc This also works with the dir command at the net>_ prompt. changes for PC version: Async interface for kiss and slip devices is now under control of an external device driver, an interrupt driven int 14 handler (COMBIOS). This can be either MBBIOS or FOSSIL, well known with w0rli & wa7mbl sysops, and FOSSIL is from the world of fido / opus phone bbs systems. see documentation within "MBBIOS.ARC" and "X00Vxxxx.ARC" for more info about mbbios and fossil. to attach a COM port use: attach com <number> slip|ax25|nrs <label> <mtu> <baudrate> <handshake> [<call>] <number> is the COM port number (1, 2, ...) slip, ax25 of nrs specificies the protocol to be used (ax25=KISS) <label> is the name of interface (144, 430 etc) <mtu> is the maximal transmission unit (paclen) (256 for ax25) <baudrate> can be selected from these values: 110, 150, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, 330400. The high baudrates (> 9600) mean "asking for problems". A standard XT can reliably run up to 4800, a fast AT can probably manage 9600 baud. <handshake> is a letter "n" of "h", and specifies the use of hardware handshaking (RTS/CTS) on the COM port. This would normally not be used, but it is rumored that AEA TNCs which exhibit the wellknown KISS bug would run more reliable when hardware handshake is in effect. <call> is needed for ax25 and nrs interfaces only. It is the IP call used for this interface. Examples: attach com 1 ax25 144 256 4800 n pe1chl-2 attach com 2 ax25 430 256 9600 h pe1chl-7 attach com 3 slip sl0 1024 9600 n Remember that the translation of COM port number to hardware address is now performed by the MBBIOS or FOSSIL. These programs must be properly configured to match your installation. Read the documentation of these programs! starting this release, smaller versions of NET.EXE are available for those stations who don't need all the features of the big NET.EXE. these versions do not include the NET/ROM code, the rcmd server and some of the more exotic device drivers. they are suitable for packet-radio-only users that do not want to leave their system on unattended. 871225.33.PE1CHL.890206: additions: netrom supports route [<call>] command. scc driver included. see sccdoc.arc file on this disk. buffers [<no. buffers>] command included. Specifies the number of receive buffers for the scc interrupt handler. Belongs to the scc driver. shell can now start a dos program. (instead of an interactive shell) syntax: shell /c <program name> [<program options>] In fact, "shell" starts the program identified by the environment variable COMSPEC, and passes it the parameters you specify. See your DOS manual for an explanation of the /c option (which is interpreted by COMMAND.COM). On the Atari ST, the shell program to be run is specified using the special form: shell =programname 871225.33.PE1CHL.890115: == Known bugs solved in this version: Scanning of HOSTS.NET file improved. usage of tab and space characters is allowed now. == Added features: Record <filename> now also works with ftp and finger sessions. Upload off aborts an uploading session. Control characters are echoed to the screen as ^<character>. They are however still sent as control characters. With ^V it is possible to insert ANY control character. Type ^V, followed by the control character you want to insert. (ref. tnc2) SMTP server is now capable of automatic multi-hop forwarding: By adressing to: john%la4zzz%sm7zzz%oz2zzz%dl3zzz@pa0zzz When the smtp timer counts to zero, or a smtp kick cmd is given, the mail is first sent to pa0zzz (the local station). The mailer chops off the rightmost call and @, replaces the rightmost % by an @, and puts the mail in \spool\mqueue. This process repeats itself (when everybody is working with this version of NET) until john@la4zzz is reached. Of course there has to be a path of known stations running NET 24h/day. 871225.33.PE1CHL.881202: == known bugs solved in this version: AX25 connects were lost at midnight (00.00: *** LINK FAILURE) (only pc version) The control block adresses are now 4 hex digits again (no ffffedca any more) Temporary files are erased again. (no "eaaaaa22.591" files in various dir's) == new features: Log command now also flushes the buffer contents to the logfile. Type command has an extra parameter: the number of lines to type example: cd \spool ;go to spool dir log ;flush buffer to file type net.log -10 ; list last 10 lines of net.log to see who is doing what. Memstat command gives the # of malloc errors not at the beginning, but at the end of the list New server: rcmd (remote command server) format: start rcmd [<port> [<key string>]] defaults: <port>=333, <key string> = null e.g.: start rcmd 333 qwert2yuiop5asd8fgh6jkl1zxcvbnmqwe5uiashjkzxcbn1234567890 (to be inserted in autoexec.net file, together with the starting of the smtp/telnet/ftp/echo/discard/finger servers) accessible for remote stations with: telnet <hostid> <port> e.g.: telnet pe1zzz 333 (from net>_ command line) the rcmd server then returns three series of random numbers, five each. One of these series must be returned with the corresponding characters from the key string. e.g.:suppose that the server was started with this line: start rcmd 333 gqweGrerDFtDyuWioGpRaYsdYJfJhIKjLzxYcfRGwevbFEnSWmlcfkHtldrDC then, a session could look like this: telnet pe1zzz 333 rcmd 871225.33.PE1CHL.881202 pe1zzz.ampr 58 24 3 18 32, 59 13 26 12 25, 71 23 12 8 44 ryJDY /* we choose the second series of numbers*/ pe1zzz.ampr net>_ At this point, the user is in complete control of pe1zzz's NET system ! This can be very dangerous, because there are dos commands like delete and chdir, and your complete system is within reach. It is important to make the key string as long as is practical, for example 50 or 60 characters, all for the sake of safety. In theory it is possible that someone monitoring the channel can, after a while, reconstruct the key string. Therefore it's a good practice to change the string after a while. This server is specially meant for automatic stations without operator. Don't start the server just to impress other people !. And whatever you do: CHANGE THE DEFAULT KEY STRING !!!! 871225.33.PE1CHL: Long forgotten history....
