- Herewith 10 easy steps to installing CAP with IPTalk:
-
- 1. Make sure that you have the latest CAP code. If in doubt, FTP the CAP
- FAQ file mac/cap.patches/CAP.faq from munnari.OZ.AU. It contains a list of
- the sites where CAP is available, please choose the closest site.
-
- 2. Run the CAP Configure program, answer all of the questions with the
- defaults (by hitting RETURN). Run gen.makes to create the makefiles.
-
- 3. Find out the IP address of the CAP host, say 132.45.67.89. This is a 32
- bit number represented as four 8-bit quantities written as decimal numbers.
- It could also be represented as a hexadecimal number, 0x842d4359. The CAP
- host node number is the bottom eight bits of the IP address, written as a
- decimal number, in this case 89.
-
- 4. Find out the IP address of the IPTalk compatible gateway, such as a
- FastPath, GatorBox or MultiPort Gateway, say 132.45.67.90. The "bridge"
- node number is the bottom eight bits of the IP address, in this case 90.
-
- 5. Check that the top 24-bits of the two IP addresses are identical, in
- this case 132.45.67. For simplicity I'll call this the IP subnet number.
- If they do not match you have to investigate the atalkad administration
- package, or use CAP with Native EtherTalk or one of the AppleTalk routers.
-
- 6. Find out the IPTalk network number being used by the gateway. This is
- a 16-bit number represented as two 8-bit quantities separated by periods
- or a single decimal number. For example 93.57 is 93*256 + 57, or 23865.
- Each IPTalk network number is uniquely associated with one IP subnet
- number, each IPTalk installation must have a unique network number where
- the IP subnets differ.
-
- 7. (optional) Check all the other network numbers in use on your network,
- make sure that the IPTalk network number is not being used for LocalTalk,
- EtherTalk (Phase 1 or Phase 2) or on any other IPTalk network where the
- IP subnet numbers differ.
-
- 8. Find out the zone name associated with the IPTalk network number. This
- may be the same as other zone names on the network but must be identical
- to the zone name programmed into the IPTalk gateway. eg: unimelb-CompSci
-
- 9. Create a file called /etc/atalk.local using the template provided in
- cap60/etc/atalk.local and the UNIX manual entry in cap60/man/atalk.local.5
- As a minimum, the file would look like the following, using the numbers
- from the examples used above, comment lines start with a '#'
-
- # mynet mynode myzone
- 93.57 89 unimelb-CompSci
- # bridgenet bridgenode bridgeIP
- 93.57 90 132.45.67.90
-
- 10. Find out what UDP ports are being used on the IP network. These are
- also called the "NIC Assigned" ports. These ports map to AppleTalk socket
- numbers and are used to deliver packets to the correct UNIX processes. By
- default, CAP will use the ports starting at 768 so that the RTMP socket
- number 1 maps to UDP port 769 and the ECHO socket 4 maps to 772. The
- official port range starts at 200, so RTMP becomes 201 and ECHO becomes
- 204. To ensure that CAP uses the official ports, add the following entries
- to the file /etc/services or the NIS database
-
- at-rtmp 201/udp
- at-nbp 202/udp
- at-echo 204/udp
- at-zis 206/udp
-
- The port numbers should already be defined in the gateway configuration.
-
- Continue testing from the [10] Verification step in cap60/doc/install.ms
-
- Note: if you are using CAP with Native EtherTalk then ignore all but step 1.
- The Native EtherTalk code is able to learn the network configuration. If
- you have an /etc/atalk.local file, you should remove it. If there are no
- other routers on the network, start aarpd with "*" as the zone name. The
- UDP ports are also used in Native EtherTalk, as markers for sockets in use.
- If a CAP process has trouble starting the ZIS listener or ECHO or NBP
- sockets are unavailable, consider installing the official UDP ports.
