and here the browser stops writing without showing a "next" button
If after this i point to the home page of my OpenACS installation, i get the following:
______________________________________________
Thank you for installing the Open Architecture Community System (OpenACS), a suite of fully-integrated enterprise-class solutions for collaborative commerce. This is the OpenACS Installer which performs all the steps necessary to get the OpenACS Community System running on your server.

pressing the next button moves me to url:
http://myserver.com:8000/packages-install?
with a

"Cannot find server or DNS Error
Internet Explorer "

error.

I use Redhat 9.0 and followed bot the automated and manual installation of OpenACS 5.0.2

Any suggestions?

Here is the error log after the point in question:

There was no mislead by documentation, i just thought i had red hat 9.0 instead of 8.0
