Description Johann Burkard 2002-12-17 11:14:59 AEDT 
When using invalid port numbers, SSHD doesn't want to start up. Imagine you made
a typo and sshd_config lists

port=601337

# /usr/sbin/sshd start 
/etc/ssh/sshd_config line 9: Badly formatted port number.  

If I start a piece of software, the software must assume that I want to use it.
If SSHD encounters an invalid value, it should handle the error (maybe by
binding to port 22 and logging the error). It should not just exit - software
should be error-tolerant and this isn't.

Starting a service when the configuration is incorrect.  Mainly when it is a very important like a port is outright wrong.  OpenSSH acts correctly
