[Zope] changing port from 9673 default

[George Perry]

I just installed zope on a debian testing (actually libranet) system
(hostname guppy).  This system is intended to be a dedicated server for an
in-house application.  I would like people to be able to access it with out
specifying the port number.

I changed the /etc/zopectl/zopectlrc file line from
  HTTP-Port: 9673
to 
  HTTP-Port: 80
and restarted /etc/init.d/zope - but the zope welcome page was still only
available from http://guppy:9673

Thanks in advance for any suggestions on addressing this.

Thank you,
George Perry
