un_untamo: prevents "untamo" daemon from logging out idle terminal

[Chuck Cranor]

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 at 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 at maria.wustl.edu or
X * cranor at udel.edu (no flames please!).
