RE: [Linux-cluster] Two-node setup Help (RHES5)



Nope, no packets between the two nodes.  This tells me that they cannot
communicate.

Maybe it's overkill, but it's pretty straight-forward to check whether
each of your nodes is receiving multicast cluster packets from the other
node using tcpdump. Assuming you've got everything on eth0 and your
other node's IP address is 192.168.1.100 you would use (with root privs)

tcpdump -v -nn -i eth0 ip multicast and src 192.168.1.100

You should see some packets from your other node sent to the default
cluster multicast group IP address, which is probably 225.0.0.11.
