Just installed zope from source on a fresh Linux-box. Defined a zope-user and a zope-group to run Zope and everything works just fine if a run it with the default z2.py. I want to run it on a different ip, an alias to eth0, and on port 80. But when I change z2.py to reflect this I get an error running start in the Zope-folder. All ports with numbers < 1024 are privileged ports. A server can bind to them only, if run as root.
