Public bug reported:
Binary package hint: lsb
lsb-base: /lib/lsb/init-functions appears to let the script
/etc/init.d/ssh, from package openssh-server, continue with status OK
even if the daemon fails to launch.
I can run the script, but no sshd is launched:
$ sudo /etc/init.d/ssh start
* Starting OpenBSD Secure Shell server sshd
[ OK ]
$ pgrep -l sshd || echo Not There
Not There
If I launch sshd manually, it gives me a proper error message:
sudo /usr/sbin/sshd -Dd
debug1: sshd version OpenSSH_5.1p1 Debian-6ubuntu1
[snip]
debug1: Bind to port 22 on 192.168.0.5.
Bind to port 22 on 192.168.0.5 failed: Cannot assign requested address.
I expect that in such a situation /etc/init.d/ssh should show an error,
something like this:
$ sudo /etc/init.d/ssh start
* Starting OpenBSD Secure Shell server sshd
[ FAIL]
Starting sshd failed : Bind to port 22 on 192.168.0.5 failed: Cannot assign
requested address.

Description: Ubuntu 9.10
Release: 9.10
If someone misconfigures the server and then uses /etc/init.d/ssh to
restart the server. They will get locked out (aka denial of service) if
they did not plan carefully enough to test which processes are running,
that's not something your average sysadmin should be expected to do.
The script should work...
