IRC bouncer cannot connect to irc server.
Hi Guys.
I've been trying to get an IRC bouncer app called muh working on my VPS hosting account but I think the firewall's getting in the way.
I have setup the app on my own personal machine and it works fine but then there's only one simple filters table with very simple INPUT/OUTPUT rules (accept tcp 6667 input, accept tcp 6667 output).
My VPS account's OS is CentOS 5 (kernel 2.6.18-028stab059.5)
I'd like to also note I'm a bit of beginner when it comes to networking, so... please go easy on me!
Here's the output from my VPS:
Code:
root@server [~]# service iptables status
Table: mangle
Chain PREROUTING (policy ACCEPT)
num target prot opt source destination
Chain INPUT (policy ACCEPT)
num target prot opt source destination
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
num target prot opt source destination
Table: filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination

2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:6667
Chain FORWARD (policy ACCEPT)
num target prot opt source destination
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
1 acctboth all -- 0.0.0.0/0 0.0.0.0/0
2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp spt:6667
Chain acctboth (2 references)
num target prot opt source destination
Table: nat
Chain PREROUTING (policy ACCEPT)
num target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
num target prot opt source destination
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Basically, muh needs to connect to the irc servers on port 6667 or 7000 and listen for connections on port 6667 or some other.
I was kind of overwhelmed by the two new tables ('nat' and 'mangle' -- neither of which I know what to do with).
There's 3 different IPs pointing to the same machine -- I'm not sure if that complicates things or not. I know muh config has an option for specifying listening IP, it's commented out (by default) and when I run muh it says it's listening on the right ip/port.
Its logs however show that it attempts to connect to the irc servers (port 6667/7000) and times out, then terminates.
Code:
root@server [~/.muh]# nmap localhost

Tried running as both root and other unprivileged account. No luck.
Any suggestions are welcome.
Thanks for looking!
