When I posted this response to omegaman's query, I was assuming
that in a properly configured RedHat system, normal (non-root)
users are not permitted to run reboot, halt, shutdown or any of
their incarnations, unless they are allowed to as sudoers.
So I assumed that omegaman was referring to ctrl-alt-del,
which assumes physical contact with the machine, since you can not
"ctrl-alt-del" across the network. My suggestion, therefore, was
to restrict physical access to the machine to the authorized
users: the system administrators.
I made this suggestion since a few weeks earlier, this question
of access was a "hot" issue at Ateneo. Should student sysads
hired on a part-time basis be allowed to bring in their non-sysad
friends into the server room? Dr. Ben Yumol's suggestion, and I
agree with him, was to enforce strict access rules into the
server room. Who should be allowed? Should the room be locked?
What about people applying for accounts? Etc.
The reason I am mentioning this again is, I think that from the tone
of our postings, we are becoming passionate ( to say the least),
and personal about this issue. We can share our love for Linux
without hurting each other. Please let us do so.
