Description Tomas Mraz 2005-09-09 07:36:46 UTC
+++ This bug was initially created as a clone of Bug #67624 +++

From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020412

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:

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

which version of openssh is installed (and showing the error)?

openssh-3.1p1-5 -- the most recent security update.

    We had an Issue Tracker ticket opened on this today. Do you know when your
patch will be included in an openssh-server errata for RHEL 3 and RHEL 4? I
checked openssh-server-3.6.1p2-33.30.6 from the RHEL 3 U6 beta and it's not there.

Comment 13 Bob Johnson 2006-04-11 15:56:44 UTC
This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 3.8 release.  Engineering 
resources have been assigned and barring unforeseen circumstances, Red 
Hat intends to include this item in the 3.8 release.
