Notes on making rsh work
- The permissions on .rhosts MUST be 600; 644 won't work.
- The name of the host you're connecting from must be listed the same way
in /etc/hosts.equiv (for system wide access) or .rhosts (for individual access) as
they are in /etc/hosts. That is, if the names are fully qualified in one place, they
have to be the same in another. To check this, telnet into the remote host and do a
'who' ('who -R' on HP-UX) to see what machine name the remote host thinks you're coming from. If it's the
short name, don't use the fully qualified name in the hosts.equiv and/or .rhosts, and
make sure you have both that form of the name in the hosts file (you can have both forms
in the hosts file).
