Why not?  What do you mean by "going through sudo"?  Sudo really is
your friend in a secure environment.

Just do "sudo tail -f /var/log/messages" and type in your password.

(or fix sudoers so it doesn't ask for a password - I add myself to
group "wheel" and set up group wheel in sudoers that way..)

I think this is the same problem - the question is, what are the
possible solutions to that problem...

tail -f /dev/tty12

or sudo tail -f /dev/tty12

or sudo multitail /dev/tty12

(never heard of multitail before, love it!  that will allow me to cut
down the number of log monitoring windows...  I monitor with swatch
and tail on system logs and apache logs...)
