UNIX for Dummies Questions & Answers

hi frnds,
how to make the ssh service to behave as rsh.as we know ssh asks for passwd whereas the rsh doesnt.so how can i perform the followin operation
without being asked for passwd.
lets say i want to run the command "ls" on "remote_terminal"
$ssh remote_terminal ls
the above should work as if i'm doing
$rsh remote_terminal ls


thanks in advance.

You need to set up public-key authentication. There is much information on this board and google, so please do a search.
