Limiting Processes

[Shane Hale]

It's not so much a load issue.  I don't want these users constantly
connected, as they treat it like a bot service, which we are far from.
We have edited the login.conf but to no luck.

You can set per-process cpu limits in /etc/login.conf (the cputime
capability).  Although you may be misreading the CPU column.  It's in
minutes:seconds.fractions, so for example
 
> beastah 29501  0.0  1.2  3324 1460  p3  Ss+  11Apr03   2:37.11 BitchX
-n BeAsTaH irc.gamesnet.net (BitchX-1.0c19)

This user started a session on the 11th, and it has consumed 2 minutes
of CPU time.  Not all that much for 17 days of real time.  If you have a
CPU load issue it's probably someplace else.

If you just want to kill long-running processes on principle, the idled
utility in ports/sysutils/idled might have a way to do that.
