OK, you've confirmed your Apache install on the Linux box because you can see your web page. Since you've also confirmed the network is working with ping, it could be your firewall not allowing the connection to port 80. That error about no response from server says it's not responding to connection attempts. On your XP box can you try telnet 18.104.22.168 80
(using the real IP address for your Linux box) to see if you can connect to the web server?
If that also fails... It's been a while, but I think the Redhat firewall scripts are in /etc/rc.d/init.d and called something like iptables or firewall. You can try temporarily turning off the firewall by running service iptables stop
(or firewall, etc - depends what it's called) and re-trying the connection. If that works the firewall needs to be modified to allow connections to port 80.
I'd recommend emailing the moderators (reporting your own post should do it) and asking for this thread to be moved to the Redhat forum http://www.linuxquestions.org/questi...splay.php?f=31
. That way there's more chance that someone currently using Redhat (instead of my rusty memory) will be reading your post.
