centos 6.x gluster --version glusterfs 3.2.7 built on Jun 11 2012 13:22:29 The problem is that when i'm trying to probe like this: gluster peer probe [hostname] It never probe's because the firewall is blocking (when I turn it of on both sides everything works) But I want to keep the firewall running. A google search give's me serveral possible ports to open , so I end with this: iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 2049 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 54539 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 38003 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 616 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 24007:24047 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 49152:49162 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 111 -j ACCEPT iptables -A INPUT -m state --state NEW -m udp -p udp --dport 111 -j ACCEPT iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 38465:38470 -j ACCEPT service iptables save service iptables restart But still not working. What port do I have to open ? -------------- next part -------------- An HTML attachment was scrubbed...
