Read the man page for rshd (you probably have, but typically the important stuff is buried in the middle of some paragraph on page 3...).

I wouldn't use hosts.equiv, but check file permissions on .rhosts (should be r/w by owner only). Also, how are you resolving host names (DNS, /etc/hosts)? Sometimes you need to use the IP address in .rhosts instead of the hostname, if no name resolution is currently in effect. There is some kind of minimal security in rshd that tries to match incoming host identification against what you've entered.

Pretty sure this is not Linux specific, same story under Solaris, HP-UX, etc.
