We have an ERP package installed on our server which requires some
maintenance from time to time.
To preform this maintenance I have to make sure all users stay off the
system (even those logged in through a web-interface) and the ones who
telnet in also.
I just can't have them use the database but I still need to use it to
perform the maintenance.
Problem is the software uses only one user to access the DB and I can't
just keep that user off the system cause then I can't do the
maintenance either.

So the question is, how can I keep users from starting new processes on
the server while I am doing the maintenance. All users that is with the
exception of myself and root.

Any suggestions might help point me in the right direction.

Thanks

This might get you close to what you want:

or you could run a script that specificaly locks out all the users you
don't want in during your maintenance.

Why not lock the user DB-user for rlogin, login with your own
personalized account and su to the DB-user?

Try rebooting, then creating an /etc/nologin file.
This prevents any user (except root) from logging in.
Then su to the user for maintenance, and remove the /etc/nologin file
when you are done.
