I've seen bits and pieces of this discussed, but I haven't found an answer to this problem. We're trying to move to an installation with Zope 2.6.2 and ZEO 2. We currently run Zope 2.6.1b2 with Zeo 1. I've got a client and a ZEO installed, compiled as the user zope. If I start the ZEO with the following command: sudo -u zope python2 start.py -h xxx.xxx.xxx.xxx -p 7700 And start the client with the following: sudo -u zope /usr/bin/python2 $cwd/z2.py -D -a xxx.xxx.xxx.xxx -w 8080 -u zope I get a working Zope on port 8080. When I attempt to do the same thing on port 80, however, the Zope, of course, won't bind to port 80 because of permissions. If I start the Zope like this, however : /usr/bin/python2 $cwd/z2.py -D -a xxx.xxx.xxx.xxx -w 80 -u zope The debug shows the zope starting up fine, with no errors at all. But it won't let me get into the site via a Web browser. The Zope thinks it's OK, but it just spins when you make a request (and doesn't log a request to Z2.log) I've tried both the stable ZEO 2.0b3 on Zope.org as well as one from CVS that was recommended on the list a while back. Any ideas?
