We have several VAXen on campus, most of which run VMS. These all offer two LAT services each - one is the node name and the other is the first letter of the node name. For example, node ABCDEF offers two services - ABCDEF and A. Both services provide equal access to the users, so typing "C A" at the Local> prompt is the same as typing "C ABCDEF". We would like to provide this same "service name alias" for our Ultrix 3.0 system. Is this possible? -- Don Rainwater, University of Cincinnati Computer Center rainwatr@ucbeh.san.uc.edu rainwatr@ucbeh.bitnet rainwatr@ucqais.uc.edu

Is this possible? According to the manuals, this is a trivial operation. In practice, I have yet to manage to get lcp to swallow anything but single-service specifications. I'd like to have BOTH the telnet gateway and normal LAT terminal service available. Has anyone figured it out? I've tried some subtle variations on the procedures given in the manuals to absolutely no avail.

There's no real problem excpept for the bogus syntax for specifying lists of terminals and the implicit association of the -v's and -V's. The biggest problem from my point of view is you can only specify seven services plus yerself. I'd modified the sample program so that it would run an arbitrary program specified in the /etc/ttys entry and was rather irritated that I couldn't advertise all the services I wanted to... Oh yeah... the description in the manual is a bit confusing - you *don't* want to reserve the ports with -h or -H, they're just "normal" lat lines, not reserved or anything... Note that the original user wanted wasn't just multiple services, instead he wanted service synonyms... This doesn't seem to be possible excecpt by cooking up a bunch of extra lat terminals/logins and having half use one name and half the other. If you try to assign a lat tty to more than one services, only the last one sticks. Anyway, here's the script I run from rc.local to start up lat: # # Start the LAT server (must start AFTER DECnet) # the -h guys are for LAT attached printers # if [ -f /etc/lcp ]; then echo "Starting LAT Services" > /dev/console 2>&1 /etc/lcp -s \ -h /dev/ttyNf,/dev/ttyNe,/dev/ttyNd,/dev/ttyNc \ -v `hostname` \ -V "Ultrix VAX 11/785" \ -v crunch:/dev/ttyXc,/dev/ttyXd,/dev/ttyXe,/dev/ttyXf \ -V "Sun 4 LSI Design" \ -v macjon:/dev/ttyX2,/dev/ttyX3 \ -V "4.3 BSD Tahoe 11/570" \ -v megafs:/dev/ttyX0,/dev/ttyX1 \ -V "MOS Megatest Sun" \ -v fortune:/dev/ttyX4,/dev/ttyX5 \ -V "Your Fate..." \ -v mentor:/dev/ttyXa,/dev/ttyXb \ -V "Mentor Ring" \ -v vps:/dev/ttyX9 \ -V "Versatec Plotter Server" \ -v telnet:/dev/ttyX6,/dev/ttyX7,/dev/ttyX8 \ -V "TCP/IP Terminal Service" \ > /dev/console 2>&1 fi exit 0 Here are my /etc/ttys entries - if I were using lattelnet it'd be similar: # # terminal running lat redirection # ttyX0 "/usr/remote/bin/latexec telnet megafs" vt100 on # LAT ttyX1 "/usr/remote/bin/latexec telnet megafs" vt100 on # LAT ttyX2 "/usr/remote/bin/latexec telnet macjon" vt100 on # LAT ttyX3 "/usr/remote/bin/latexec telnet macjon" vt100 on # LAT ttyX4 "/usr/remote/bin/latexec telnet megasun" vt100 on # LAT ttyX5 "/usr/remote/bin/latexec telnet megasun" vt100 on # LAT ttyX6 "/usr/remote/bin/latexec telnet" vt100 on # LAT ttyX7 "/usr/remote/bin/latexec telnet" vt100 on # LAT ttyX8 "/usr/remote/bin/latexec telnet" vt100 on # LAT ttyX9 "/usr/remote/bin/latexec telnet vps" vt100 on # LAT ttyXa "/usr/remote/bin/latexec fortune" vt100 on # LAT ttyXb "/usr/remote/bin/latexec fortune" vt100 on # LAT ttyXc "/usr/remote/bin/latexec telnet crunch" vt100 on # LAT ttyXd "/usr/remote/bin/latexec telnet crunch" vt100 on # LAT ttyXe "/usr/remote/bin/latexec telnet crunch" vt100 on # LAT ttyXf "/usr/remote/bin/latexec telnet crunch" vt100 on # LAT -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
