Linking Remote Logins

If your system is configured properly, you can link remote logins. For example, a user on earth logs in to jupiter, and from there decides to log in to pluto.

The user could have logged out of jupiter and then logged in directly to pluto, but this type of linking can be more convenient.

To link remote logins without having to supply a password, you must have the /etc/hosts.equiv or .rhosts file set up correctly.
