[Zope] can't seem to get zope working on RedHat Linux 9

Have Zope installed and started on RedHat Linux 9. Attempts to browse to http://localhost:8080/manage, from local machine, or http:// <http://%3cip-address%3e/manage> <ip-address>/manage, from a remote machine, hang and/or fail after timing out. HTTP Get entries do appear in the var/Z2.log. Are others experience trouble with zope on RedHat Linux 9? Has anyone overcome trouble with zope of RedHat Lilnux 9? Thanks, Ted
