Suse 8.0 installed on each node and master. To run programs on my cluster I need to enable passwordless remote command execution with rsh, so I cant switch to ssh. I have enabled the rsh-Deamon on all computers. It has two NICs, one connected to the cluster's switch, the other to the internet. My question concerns the master: In the masters hosts.deny the entry ALL : ALL was placed and in the hosts.allow the entry ALL : (some IPs I can trust) in hosts.equiv all the cluster nodes were placed.
