Hi,

The ssh protocol works with encryption and is typically much more secure than the inetd services which can be grouped into ARPA/Berkley services. These services include telnet, ftp and rlogin also referred to as legacy services and are not that secure protocols. User equivalency can also be configured which is typically done with .rhosts configuration for which after configuration, you can go ahead doing an rlogin into an account of another user with whom you have maintained the trust without the prompting of a password. If security is a concern always go with ssh.

* SSH is a recently designed, high-security protocol. It uses strong cryptography to protect your connection against eavesdropping, hijacking and other attacks. Telnet and Rlogin are both older protocols offering minimal security.

* SSH and Rlogin both allow you to log in to the server without having to type a password. (Rlogin's method of doing this is insecure, and can allow an attacker to access your account on the server. SSH's method is much more secure, and typically requires the attacker to have gained access to your actual client machine.)

* SSH allows you to connect to the server and automatically send a command, so that the server will run that command and then disconnect. So you can use it in automated processing.

ssh the configuration file is /usr/local/etc/sshd_config.

For rlogin the file is /.rhosts.

Edit the /.rhosts file enter hostname, user name and wq!.

This is an excellent resource on what secure shell does, especially with respect to the ARPA r-commands.

Is Google broken? Is "man"?

man rlogin
man remsh ### Or "rsh", depending.
man ssh

Look first, ask later?

ssh is secure and rlogin is not, unless kerberized. there is nothing else to discuss. stop using rlogin since it is antiquated.
