[sclug] How do I kill ttyX ?

[David Ginger]

The other day I managed to completely lock up console tty2. At the time I 
tried to kill it as root from tty3. To cut a long story short, I could'nt 
kill the pid of logon tty2, and I was getting no error msgs, so I gave up, 
switched back to tty2 and gave it a Ctrl-D. End of problem.

However, for future refference / curiosity, how should this be done correctly 
from a different remote terminal at a remote physical location using ssh 
etc... ?
