can't access irc server on xen domU, please help

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi all,

I'm running a CentOS 5.2 server with a FC8 xen domU guest, and an irc server on the FC8 domU guest. For some odd reason, I can't access the irc server on the xen domU guest.

From FC8, when I run netstat -a, I can see irc is listening:

netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address               Foreign Address             State
tcp        0      0 *:ircd                      *:*                         LISTEN
tcp        0      0 *:6668                      *:*                         LISTEN
tcp        0      0 *:6669                      *:*                         LISTEN
tcp        0      0 *:ftp                       *:*                         LISTEN
tcp        0      0 192.168.10.:afs3-fileserver *:*                         LISTEN
tcp        0      0 localhost.localdomain:smtp  *:*                         LISTEN
tcp        0      0 192.168.10.13:ftp           196-209-84-62-tpr-esr:49615 ESTABLISHED
tcp        0      0 *:http                      *:*                         LISTEN
tcp        0      0 *:ssh                       *:*                         LISTEN

and running nmap on the localhost looks promising as well:

netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address               Foreign Address             State
tcp        0      0 *:ircd                      *:*                         LISTEN
tcp        0      0 *:6668                      *:*                         LISTEN
tcp        0      0 *:6669                      *:*                         LISTEN
tcp        0      0 *:ftp                       *:*                         LISTEN
tcp        0      0 196.34.136.:afs3-fileserver *:*                         LISTEN
tcp        0      0 localhost.localdomain:smtp  *:*                         LISTEN
tcp        0      0 196.34.136.55:ftp           196-209-84-62-tpr-esr:49615 ESTABLISHED
tcp        0      0 *:http                      *:*                         LISTEN
tcp        0      0 *:ssh                       *:*                         LISTEN



Yet, from the outside (either from another PC, or the dom0 itself), I can't connect to the irc ports.

I've even disabled iptables on the dom0 altogether, but stil can't connect to it.


The only open ports are:
PORT     STATE  SERVICE
80/tcp   open   http
443/tcp  closed https
7001/tcp closed afs3-callback
8000/tcp closed http-alt
8080/tcp closed http-proxy
8081/tcp closed blackice-icecap




How do I get this to work?



P.S. Sorry for the cross-post, for those of you who are on the centos-virt list as well, I just find that this list is being used more.
