I setup a linux box running Fedora 7. I installed hellanzb-0.13 and it runs fine when run from the console. I wanted to setup the web interface and configured it to run Zussaweb and moved the files to /var/www/html/zussaweb in order for it to run live on the apache server.

However, when I load up a browser and try to access the web interface, I get the following error and it doesn't load:
Fault: Code: 5 Reason 'Connect error: Permission denied (13)'

I also tried using HellaWorld and I get more or less the same error:
Connect error: Permission denied (13)

Any ideas on how to fix this or what the problem is?

sounds like a permissions problem on your domain directory.

from root run the following command

#ls -al /var/www/html/

and post the results.

I was able to correct the problem, it turns out it was SELINUX that was not allowing me to connect.
Once I set SELINUX from "enforcing" to "permissive" mode it worked great.
