<div dir="ltr"><div class="gmail_quote"><div dir="ltr">Hi all, <br><br>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. <br>
<br>From FC8, when I run netstat -a, I can see irc is listening:<br>

<br>I've even disabled iptables on the dom0 altogether, but stil can't connect to it.<br><br><br>The only open ports are:<br>PORT     STATE  SERVICE<br>80/tcp   open   http<br>443/tcp  closed https<br>7001/tcp closed afs3-callback<br>
