Hi All, hopeing that someone out there in AO LAnd can clear something up for me.

I am trying to understand the differences both from a functionality perpsective as well as a security perspective between rlogin, shell and telnet.

I know that they are all remote command-line protocols, and that some are used for host-to-host communications. I have also read that using rlogin and shell can be considered possible security risks, but I cannot seem to find out why.

Any help would be appreciated.
