Description Tomas Mraz 2005-10-11 23:28:36 UTC

+++ This bug was initially created as a clone of Bug #167886 +++

Description of problem:
The init script /etc/init.d/sshd uses the function killproc from
/etc/rc.d/init.d/functions. This falls back to using the pidof command to get
PIDs for the daemon, if /var/run/[service].pid does not exist. This means that
if the ssh server is already stopped, instead of failing with "ssh server is not
running" or something similiar, it kills all other running sshd's, which,
obviously, kills everyone's connections to the server. This has a high inpact
if the server is remote and there is no easy console access.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Log on via ssh
2.run /etc/init.d/sshd stop
3.run /etc/init.d/sshd stop again.
	

Actual Results:  All ssh connections to the server were closed.

Expected Results:  It should have returned with a failure to find a process to kill.
