26 Oh, whoops! Big mistake, you are right - sorry for that, this was bad
27 advice. I did not think about these other sshd processes. Thanks for being
28 watchful and pointing this out.
29 Still, I would prefer -HUP instead of -9, as this would make the sshd server
30 restart itself. Just in case /etc/init.d/sshd start also makes trouble - it
31 really shouldn't, but neither should /etc/init.d/sshd stop.
