I setup an IRCD server the other day. I am running the process using my user account. I can connect just fine with an IRC client locally (localhost:6667), but not from another computer..

I imagine there is a firewall stopping this from working, but I can't figure out how or where. I am running Susa 9.1. Through YaST, I disabled the Suse firewall. All my other services can be reached (SSH, HTTP, FTP, etc.), but not IRCD. I sudo'd "iptables --list", and all I got was the following:

Which suggests to me I have no firewalls going via iptables (btw, I know nothing about iptables...).

I am at a loss as to what else might be preventing this connection from working. Thoughts?

Thanks.

This sounds like an NAT problem. Do you have a router that the computer running the ircd server connects through? If so, you will have to go to that router's config page and forward port 6667 for the internal IP of the machine running the ircd server.

If you need help with that second step, let me know

I should have clarified the situation a little more - this Linux server is not running out of my home, but is a Virtual server at 1and1.com.

Ah! Well, the same thing may apply if the virtual machine uses bridged networking instead of getting it's own address from the DHCP server (and even then, maybe!)

Also, some VPS providers will intentionally block port ranges like 6660-6669 precisely because they don't want people running ircd servers and things like that. IRC servers are notoriously common and easy targets for DDOS attacks, which means very high server load for your provider. This may be intentional.

Your best bet is to contact 1and1.com technicians and ask them
a) If you're allowed to just run an ircd server
b) If they need to forward the appropriate port range for you

Your configurations inside the box seem to already be fine, judging by your post.

Just curious: what IRCD software are you using?

Thanks, that put me in the right direction. 1and1 has seperate firewall software that I have to access through their website.

Glad to hear it But seriously, you should ask permission before running an ircd server or you may find your account suspended
