Hi ,
  I have setup a B cluster. I originally had ssh
working between the guarded clusters. However, I need
to use rsh to have the processing time lower than that
caused by ssh. I got the rsh rpm pkg(RH 8.0) and
installed it on Red Hat 8.0 systems in my cluster. I
changed the necessary files on each server -
hosts.allow/deny/equiv + /xinetd.d/rsh-rlogin. Then I
tried to login from Master to one of the nodes. The
problem though, was that the connection always
defaults to ssh rather than using rsh. SO, I disabled
ssh and tried to connect using rsh from master to node
and it failed with the command 
"ssh: connect to address 10.1.1.5 port 22: Connection
refused" 
This means that it is still looking for a ssh server
rather than an rsh server. Furthermore, I can use
rlogin from Master to Node and I get connected to port
513 on the Node.  Please could someone help me figure
out this problem. I found an exact same problem in
google, however no ANSWER/SOLUTION.  
Thanks 
Sandy
