My first question is why are you using rsh instead of ssh. As for the
config files you speak of. The .rhosts file is for user to user auth,,
meaning that you would have to have the users on the machines
"foo.bar.com bob" as for the hosts.equiv file which is used for system
to system auth you need to use fully qualified names such as
+foo.bar.com bob and so on... Try logging in with the rsh -l username
linuxhost then enter the command and tell me the outcome .

OK so no reply. I will just give you the answer then . Add the user
common on both machines with the same passwd. Put the user in the
.rhosts file on the server along with the name of the other machine
and enjoy using the not as sucure rsh.

sorry chris,
i was on leave during last 2 days. and here is what i experienced. if
i had two accounts with different ids and passwords, say saleem on
'mainserv' and common on 'linuxhost', the commands:
$rsh linuxhost 'ls'
gives the same response: 'permission denied'. although i had entries
for both users in .rhosts file. now if i try this command,as u
suggested:
$rsh linuxhost -l common 'ls'
it works. but i need to do it without specifying the user name and
password. and yes, i ur last suggestion that is: keeping ids and
passwords same on both hosts works, since i already tested it.
if u had anything else in ur mind, please do reply me.
