Issue with OpenSSH 5.5p1 in RHEL 5.7 server
Hi everyone,
We just bumped into the following issue at work. All of a sudden we could not start new ssh sessions to a RHEL 5.7 server, but existing ones were kept alive. In those circumstances, these existing connections appeared to be handled by init (as the ssh daemon seemed to be down - it was not showing anymore in the list of running processes, invoked wither with top or ps -ef) as shown in the PPID of the following process list: Code:
me@rhel /home/me:ps -ef | grep ssh | grep -v grep The version of OpenSSH is OpenSSH_5.5p1. Any hints or ideas of what could have caused this issue will be more than appreciated. |
Looks like SSH multiplexing causes that output in ps.
Your problem with not being able to log in probably was because SSHd was not running, though. So look at the log files for any crash reports, and check that ssh cleanly restarts. |

Try /var/log/messages. Most service process aborts get recorded there. The others are for specific classes of messages rather than general messages.
