<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I have a cluster in which the master node can be accessed from outside by ssh and the internal nodes are secluded. Its running on Redhat 8.0.</DIV>
<DIV> </DIV>
<DIV>Well for the sake of running Fluent I had to set up the cluster in such a way that, any node can rsh to any node without a password. Now the problem is that when I type in the command</DIV>
<DIV> </DIV>
<DIV>rsh "internal node"</DIV>
<DIV> </DIV>
<DIV>It connects to the internal node by ssh. </DIV>
<DIV> </DIV>
<DIV>This is causing great delay in getting parallel work done with Fluent. I have enabled the </DIV>
<DIV>"RhostsAuthentication Yes" on all the nodes</DIV>
<DIV> </DIV>
<DIV>in the /etc/ssh/sshd_config. </DIV>
<DIV> </DIV>
<DIV>This was necessary for the passwordless login.</DIV>
<DIV> </DIV>
<DIV>Is there anyway I can communicate between the internal nodes using only rsh instead of ssh, and at the same time enabling ssh on the master node so that it can be accessed from outside. </DIV>
<DIV> </DIV>
<DIV>thanks in advance</DIV>
