The xinetd daemon is only running on node 1, so rsh requests can only be
honored there. Theoretically, it's possible to get xinetd running in
parallel on all nodes, but there may be conflicts between the multiple
daemons trying to use the same resources (i.e., files, semaphores,
In an SSI cluster, you can do effectively the same thing with the
onnode 1 echo "Hello World!"
onnode 2 echo "Hello World!"
The first example executes the command on node 1. The second does it on
node 2. In both cases, the echo is done to the console you use to enter
the command (same as your rsh example).
Hope this helps,
