[Bug 458476] Re: /etc/init.d/ssh gives OK status even if daemon fails to launch

[Robie Basak]

I can't reproduce this on Eoan, so I believe this problem is fixed. In
particular, since the init.d handling was overhauled when systemd was
introduced, it is likely that the code responsible has completely
changed and this bug no longer exists. I'm marking as Fix Released
accordingly.

Title:
  /etc/init.d/ssh gives OK status even if daemon fails to launch

Status in lsb package in Ubuntu:
  Invalid
Status in openssh package in Ubuntu:
  Fix Released

Bug description:
  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.

  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...
