- This DEFINITELY belongs in the FAQ.
-
- To solve your problems:
- The lcp line in your /etc/rc.local should have
- -h /dev/tty04:SERVER1:PORT1,/dev/tty05:SERVER2:PORT2,...
- with an entry for each printer you will use over lat.
-
- The printcap should have :ct=dev: and :lp=/dev/tty?? in it and should NOT
- have :ts=xxx:, :op=xxx: or :os=xxx: entries.
-
- If you still have problems, turn off lat with lcp -t and wait for several
- minutes before restarting it with lcp -s -h ........
- This wait gives the terminal servers a chance to forget about your node
- and reset all their connections. As far as I can tell, starting lat with
- the -h option creates a connection of some variety with the Terminal
- Server *RIGHT THEN* which is kept alive by some heartbeat like packets
- between the computer and the Terminal Server. This connection can get
- confused and you have to let the Terminal Server time it out before
- restarting lat. This explains the delay. You may also have to kill
- the lpd which is running and abort the queue with lpc but probably not.
-
- To the folks at DEC, PLEASE PLEASE PLEASE develop a workable API for LAT
- on ultrix so we can do all the nifty things that VMS does with it. I
- have jealously watched VMSers do set host/LAT for about 6 months now.
- I am also getting tired of working around the bugs in Ultrix LAT.
-
- |> Also, what does lattelnet do?
-
-
- Lattelnet is a dangerous and evil piece of software which allows others
- to log in to a TCP/IP host through your computer via LAT. It has also
- been known to allow people to remotely connect to your system as root
- without a password. Once you have started allowing people to use the
- LAT/Telnet gateway, you have opened a big security and auditing hole
- which, try as you may, you cannot fill without turning it off. However,
- if you really want to start the LAT/Telnet gateway, see the "Guide to
- Ethernet Communications Servers" section of "System and Network Management"
- manual, probably volume 4.
