I have several machines on a LAN on which ssh works fine. One machine
doesn't have sshd running. When I do:
sudo /etc/init.d/ssh start (or restart)
I get the correct message about sshd starting or restarting but 'ps ax'
does not show sshd running and, of course, I can't ssh to that machine.
There also is no /var/fun/sshd.pid .
