Hey All,
I'm trying to learn some more about Clusters for some research I'm
doing. First thing I need to say is this project is absolutely
AWESOME!!!
I've installed and enabled the Pacemaker system and I have it running.
The issue I am dealing with is that whenever IPTABLES is enabled the
cluster nodes cannot see one another. If I flush all of the rules from
IPTABLES the nodes talk to one another perfectly fine.
I have two ring interfaces:
interface {
ringnumber: 0
bindnetaddr:172.16.103.0
mcastaddr:224.1.0.1
mcastport:4000
}
interface {
ringnumber: 1
bindnetaddr:172.16.104.0
mcastaddr:224.2.0.1
mcastport:4000
}
And I added the following rules to IPTABLES:
-A RH-Firewall-1-INPUT -p udp -d 224.1.0.1 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -d 224.2.0.1 -j ACCEPT
#-A RH-Firewall-1-INPUT -p udp --dport 4000 -d 224.1.0.1 -j ACCEPT
#-A RH-Firewall-1-INPUT -p udp --dport 4000 -d 224.2.0.1 -j ACCEPT
The two commented out rules didn't work so I tried the two above.
What am I missing here?
Thanks,
Jake
