Re: lot of user
Maybe you should reconsider. 2000 users on a machine with
one partition? You're dead before lift-off.

Add usrquota and/or grpquota in /etc/fstab for the appropriate fs,
run quotaon -a at boot, and quotacheck -a every couple of days/weeks
whatever, and after an improper shutdown.

No. Well, unless they all try to logon at once (ssh can be cpu intensive
especially if using high levels of compression. Restrict to 5).

SecureCRT - very useful but costs money. There are some free ones
as well, IIRC. There is also that program from DataFellows, but

freshmeat has some programs specificly designed to handle lots of users,

tools you have if you are not familier with this. I'd
guess linuxconf?).
