[ubuntu] Port 8080 blocked?

view story

http://ubuntuforums.org – Hi All I'm trying to create a python-based website using wsgi, following instructions such as these. This all works just fine as long as I'm accessing the website from the same PC on which it is hosted. However, when I try to access it from another PC on the same network (there shouldn't be any firewall between the two), it tells me the host can't be found. I'm using port 8080 for this. If I try to host a simple website on port 80, everything is fine. So I assume the problem is that port 8080 is blocked? Is that correct? If so, how do I go about unblocking it? And if not, then what (Hardware)
