I'm trying to move my Zope instance from port 9673 to port 80 and have some fairly basic questions regarding the port configuration. In my z2.py file the parameter HTTP_PORT is set to 8080. This is the only z2.py file on the machine. In /etc/zopectl/zopectlrc 9673 referenced as the HTTP port. If I change 9673 to 80 and restart Zope I don't get an error, but I can't resolve. If I try to access port 80 while Zope is running on 9673 I don't get a page resolved. Apache is running (on port 80 according to httpd.conf). If I change Apache to run on another port (say 8080) then Zope stops working. It would seem as Zope is using Apache as a proxy, but why not on port 80. Is there a simple way to reconfigure this instance to use port 80 either via Apache or the Zope HTTP server? At present I want to access the site via IP instead of domain name. Many thanks in advance, Marc Stein
