Thanks, I'm still struggling and tried a few things, even up to the point where I shut myself totally out and had to reinstall httpd.
On the listening question: yes, it appears so...
tcp 0 0 10.0.0.5:80 0.0.0.0:* LISTEN 4615/httpd
What I mean with "can't access".... If I open my web browser from another machine in the lan, say 10.0.0.4, I can't see the default index.html in my var/www/html directory or my configured joomla directory. Browser just says... cant display the page as if it can't find it. But I can ping the linux server (10.0.0.5).
No firewalls. I think its either httpd.conf or apache.ini but don't know where and what.
