Red Hat Bugzilla – Bug 31716
reboot/shutdown behavior with openssh is bad
Last modified: 2008-05-01 11:38:00 EDT
Red Hat issues a "kill -9" to sshd when the sshd is shut down, while
Debian issues a SIGTERM. The difference in behavior is that the Red Hat
Linux sshd leaves all clients in a "stuck" state (only kill -9 able) while
the Debian sshd nicely disconnects and the clients return cleanly.
This should not be hard to fix and will spare me a lot of annoyance.
It should only do a kill -9 if it doesn't respond to a kill -TERM, looking
at the init script.
This has been my experience with recent initscripts versions as well. The
first "service sshd stop" kills the master listener, and a subsequent stop
attempt will only use kill -9 if a kill -TERM doesn't cause the sessions
Have just checked with the current tree, and the clients receive a
"Connection to host closed by remote host." message. Please reopen if
you're seeing this problem with the latest versions of initscripts and
