I found, under a 64-bit RHEL 5 server install, adding the same two lines
completely breaks the OS, to the point that a reboot after the lines are
added, the OS brings you to a fsck-like prompt, and other things break,
too. I didn't have time to look at the logs for specifics, if any were
recorded.
That's rather odd. The two files are (or should be) identical.
Does anyone know if a CentOS 5 server install option permits locking out
root from console login? Does anyone know of a way, in RHEL 5 Server
edition, to prevent root from a console login?
You can edit /etc/securetty, which controls what root is allowed to
log in from. In reality, I'd leave the console there, but block ssh
and most of the other ones. You'll want root access at the console if
something catastrophic happens and you need to recover. If they've got
local access to the machine, it's basically theirs anyway.
While you're using centos5, most of these -

should work just the same for you.
