[Xen-users] can''t access irc server on xen domU, please help
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 *:*

tcp 0 0 *:6668 *:*

tcp 0 0 *:ssh *:*
LISTEN
and running nmap on the localhost looks promising as well:
netstat -a

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?

RE: [Xen-users] can''t access irc server on xen domU, please help
Two quick thoughts:
1) What about iptables on the domU? (I suspect you have tried this, because
I believe I see your name a lot on the list, but a little reminder never
hurts)
2) What about running netstat with another switch to show which application
is running on the ircd port in case it isn''t actually your irc server
(this
is assuming you haven''t done basic port troubleshooting like telnetting
to
that port just to verify that the connection can in fact not even be
established).
Beyond that, I guess you''re into xen networking troubleshooting
territory, and there is a quite a bit of that in the list history, but for
anyone on the list to help you, they will probably need more info (which
someone might ask for), as for me, I haven''t done enough xen network
troubleshooting to be of assistance. Good luck,
Dustin
