cranor@udel.edu (Chuck Cranor) (11/01/89)
This is a quick hack I had to put together for use at my new school (wustl).
It prevents the Purdue "untamo" daemon from logging you out when you are
idle. Since I run the "screen" program from comp.sources.unix I never
logout my main logins...I just "detach" from my screens and then re-attach
to them when ever I login. I've included a "Makefile" generated by
the "mkmf" program...

X * un_untamo.c 11-Sep-89 Chuck Cranor <cranor@udel.edu>
X * This program defeats part of the "untamo" daemon from Purdue.
X * It has run correctly under SunOS 4.0 and Mt Xinu 4.3+NFS unix.
X *
X * "untamo" can be configured to logout "idle terminals".
X * This "feature" of the program may not always be desirable.
X * The "un_untamo" program (designed to be run by your login shell via .login
X * or whatever ...) runs in the background and touches your terminal
X * device every 5 minutes. This prevents your idle time from going
X * above 5 minutes. The program exits when it detects that
X * it's parent has exited/died (e.g. you logout). [It does this with
X * kill(0,pid)]
X *
X * Please send comments/bug reports to: chuck@maria.wustl.edu or
X * cranor@udel.edu (no flames please!).
