From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040925 Description of problem: Every few days (usually during network outages) it becomes impossible to contact a RHEL3 server via SSH, resulting in the need to hard reboot the machine to recover. The only clue of a problem is logged in /var/log/secure: Jan 11 17:28:57 rachel sshd[1698]: fatal: Timeout before authentication for 172.16.254.50 Google shows a singificant number of people with the same problem, but nobody yet has found a solution. The pattern seems to be this: The DSL connection linking the box to the net goes down for reasons unknown. At this point it becomes impossible to SSH to this box over a private local network, giving the error above. Rebooting the box brings the box back to life until the next opportunity to fail, currently every few days. It is not clear as to when this problem started, as the problem is only triggered during network outages (common during the current storm season). It may have been introduced with the last update to openssh, whenever that was. Version-Release number of selected component (if applicable): openssh-server-3.6.1p2-33.30.3 How reproducible: Sometimes Steps to Reproduce: xxx Additional info:
Could you test the packages from http://people.redhat.com/tmraz/testing/ if they solve your problem?
Will do - thanks for getting back to me.
