Clients Connection Problem

[dasgar]

I've got Unreal installed on a FC4 system. (I have not run any updates on the system, which is a test system and has no internet connection.) Unless FC4 by default installs a firewall, there is no firewall. At the moment, the system running the unrealircd is the only system that can connect, but it is using the loopback IP (127.0.0.1). All other systems are reporting a "no route to host" error in their irc clients. In the listen block, I only have the * wildcard rather than an actual IP address for the ports. This system only has one NIC and one static IP for that NIC. The netstat command is indicating that nothing is listening on port 6667, despite the fact that this is the ported listed in the listen block and unrealircd is up and running. It looks like unrealircd is either only listening on the loop back IP and/or is not opening port 6667 on the NIC's IP address.

Does anyone have any ideas on what the problem may be or any suggestions for me to try out? Unless I overlooked it, I couldn't find any information on this in the online documentation of the FAQs. The only other thread that I found on this topic involved a firewall issue, which I don't believe applies to my situation.

iirc FC4 does install a firewall default unless you specify it not to during install. Stealth would know more about it

Try using an actual IP address and see what happens. Although it won't help much if it is indeed a firewall issue.

Feeling stupid now.

I'm still fairly new to Linux and didn't realize that FC4 automatically installed and enabled a firewall. Bad assumption on my part. Once I disabled it, everything worked. Sorry about bothering everyone. Now I'm off to go bang my head against a wall for a few minutes. I guess I can take comfort in the thought that I'm not the first nor will I be the last person to ask a stupid question. Thanks for the input guys.
