SSH - Secure Shell
Summary: We recommend that you use Secure Shell (ssh) as an encrypted alternative to telnet and remote shell.
SSH -- what is it?
Secure shell (ssh) is an encrypted alternative to telnet and remote shell (rsh),
wherein each packet is encrypted from the source to the destination. This prevents
your communications (including passwords) from being 'sniffed' while in transit,
as is known to happen with traditional telnet and rsh.
Using SSH insures that your data packets are only readable by you and the computer
to which you are connecting.
