Hi all, I am a problem with ssh and the firewall on my new Rocks 5.1 cluster: -firewall on -I can ping all compute nodes but ssh hangs...
-firewall off -I can ssh into compute nodes. Since I installed the system I did not touch the iptables. Below is the iptables on my system. Any idea what really happens and how to fix it?
