openssh unix dev - Dec 2002 - [Bug 457] New: SSHD doesn't start when using invalid port numbers

http://bugzilla.mindrot.org/show_bug.cgi?id=457

           Summary: SSHD doesn't start when using invalid port numbers
           Product: Portable OpenSSH
           Version: 3.5p1
          Platform: ix86
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: sshd
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: granularr at 7ucid.com


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.

i completely disagree with this.  i believe it IS handling the error exactly as
it should, by refusing to run.

i would rather find the error immediately and fix it than have the software try
and
guess what i really meant.
