Dear experts,
Thanks a lot for your help.
Unfortunately the problem is not there. Looks like something is wrong with
the ports.
Included are the TCPDump results.
Thanks in advance.

Another possibility is to check /etc/hosts.equiv to make sure it calls out
all the hosts. We found on our system that we needed entries in hosts.equiv
for all the nodes or rsh gave us the "connection refused" error message.
Merely adding the hosts to .rhosts did not do the trick.

Subject: Re: LAM: rsh fails
'Connection refused' suggests to me that the rsh daemon is not running on
one of the nodes. Restarting the service depends on the OS/host. Under
linux it is most likely run through inetd or xinetd. So check
/etc/inetd.conf or /etc/xinetd.d/rsh and make sure its set to run in.rshd
(the daemon for rsh). Then you can try 'service inetd start' or 'service
xinetd start'.
Alternately it could always be a firewall rule problem.
If rsh is running standalone without inetd or xinetd try doing a 'ps aux |
grep in.rshd' or a 'ps -ef | grep in.rshd'. This will show you if the
daemon is running or not.
Hope that helps,
Peter McLachlan

Subject: LAM: rsh fails
Dear experts,
I can't setup my LAM system now (used to work before).
When I use rsh command from the 1st computer to the 2nd one, I receive a
message "poll: protocol failure in circuit setup". When I use rsh command
from the 2nd computer to the 1st one, I receive a message "Connection
refused".
Home directories have 755 permissions. Files .rhosts are present in home
directories with 644 permissions.
Thanks a lot in advance.
