Herewith 10 easy steps to installing CAP with UAR: 1. Get the UAR package (mac/uar.tar.Z) via anonymous FTP from munnari.OZ.AU and place it in a local directory 'uar'. 'cd uar', un-compress and un-tar the package with 'compress -d uar.tar.Z' and 'tar -xvf uar.tar' 2. Check the README to ensure that your host is supported, currently UAR supports Phase 1 and Phase 2 EtherTalk networks connected to SUN, DEC ULTRIX, SGI IRIX, Sony NEWS 4.2, HP-UX and IBM RS6000 AIX workstations, and Phase 1 only on Sony NEWS pre-4.2 workstations. 3. Edit the 'Makefile' to add the necessary info to CFLAGS= and LIBS= The requirements are listed per machine type (only NEWS, AIX & Solaris 2.N). 4. Compile the program by typing 'make'. If compilation procedes without error, type 'make install'. This step copies the binary to /usr/local/cap/uar 5. Decide on whether or not you are going to run UAR as a "seed router". That is, if UAR is to be configured with details of your local AppleTalk network or is to determine information empirically from the network. For UAR to function as a "seed router", you must create a uar.conf file that contains network number(s) and zone name(s) for each of the participating ethernet interfaces on your UAR host (see the sample uar.conf provided). The information in uar.conf *must* be identical to the configuration in any other AppleTalk routers on the local networks, this is not optional! Normally your campus/institution network manager is the best source of such information. 6. If you are absolutely certain that there are no other local AppleTalk routers then you may choose numbers for the "network", "networklo" and "networkhi" entries. A "node" entry is optional. Network numbers are 16-bit quantities and can range from 1 to 65534 (the values 65280 to 65534 are reserved as the "startup range" on Phase 2 networks, don't assign a network number in this range). These 16-bit numbers can also be represented as two decimal numbers separated by a dot. In this notation, 56284 is represented as 219.220 (ie: 219 x 256 + 220). The node number is an 8-bit number, the valid range is 1 - 254 on Phase 1 AppleTalk networks and 1 - 253 on Phase 2 AppleTalk networks (assume Phase 2 for recent Macintoshes unless you know otherwise). Node numbers specified for UAR should be towards the high end of the range, ie: 253. You must also choose a zone name or list of zone names for your network, in the latter case specify one of them as the "default" zone name. The interface names are the device names for your ethernet interfaces and can be listed using the command 'netstat -i'. Under AIX, use "ent0", "ent1" rather than the listed "en0", "en1". 7. Ensure that your CAP distribution is at least at patch level 144. Run the Configure script and answer 'y' or 'yes' to the question "Do you wish to use UAR (Unix AppleTalk Router) (default no) ?" and 'y' or 'n' as necessary to "Do you want Phase 2 compatibility (no) ? " Run 'gen.makes', 'make include' and 'make programs'. See the CAP documentation for more details. 8. To use UAR with CAP you must specify an interface for CAP to be "attached" to. With a uar.conf file, this is achieved with a "cap on" entry, all other interfaces should have "cap off". If no uar.conf file exists then run UAR with a -C option. This attaches CAP to the first interface name listed in the UAR arguments. 9. Run UAR. For example, on a single interface machine where UAR is used only to support CAP (and not in it's usual function as an AppleTalk Router) you would use uar -C le0 or, on a multiple interface machine uar -C ie1 ie0 where CAP is attached to "ie1", or with a uar.conf file uar et0 enp0 where "et0" and "enp0" are listed in the uar.conf file with "interface" entries containing network and node numbers, zones and one "cap on" entry. 10. Check for "/etc/etalk.local" created by UAR. Normally this takes up to 15 seconds to appear (so in a start-cap-servers file insert a "sleep 20" after starting UAR before starting the rest of the CAP programs). With CAP compiled for use with UAR it should now be possible to run test programs such as 'cap60/samples/getzones' and 'cap60/samples/atlook' and see meaningful results. If not, consult your local network administrator or send email to uar@munnari.OZ.AU. Please note that UAR vers 1.0 is FreeWare. A ShareWare or site-license fee is payable for UAR version 1.1.
