Hi,

you may check somes points :
- does your /etc/hosts.allow|deny allow your machines?
- does it uses PAM?
If yes (for PAM), I think you need to add 'rsh' to the /etc/secuetty file.
For the first point , appart if you do not set restrictive access at all,
you should have entries like:
in.rshd: <network/mask>

And do you check the messages generated by rsh on your target
machine?
It may be in /var/log/messages or /var/log/secure.

Oh, you don't forget to install rsh-server on your target nodes?

Hope it will help.
