The rc script for sshd currently uses the following line to determine the PID of any running daemons:
PID=$(pidof -o %PPID /usr/sbin/sshd)

This incorrectly matches any processes of users *already* logged in, even if the actual listening daemon is not running.

Perhaps a better way is to use pgrep or `netstat -tnlp | egrep '/sshd$'`

Additional info:
Version : 5.3p1-4

Steps to reproduce:
1) Login via SSH
2) Shutdown the sshd daemon
3) Attempt the restart the daemon. It will fail because the PID identification line above incorrectly matches the sshd process of your login.
