SSH
SecureSHell is an enhanced Shell used for secure (encrypted) communication with a remote computer. It is the preferred replacement for Telnet.SSH
SSH encrypts ALL traffic.The login transaction and all further traffic is secured against casual eavesdropping.
It is worth mentioning that scp is a Secure Copy program that adheres to the same principal and is usually (?) packaged with the SSH program.
Telnet
Telnet is a shell without any security features (encryption).Login passwords and all further transmissions are sent in the clear. ie:- anyone with access to the traffic has the potential to read it.
Telnet still has it's uses (checking mail accounts, server versions) and SSH can be vulnerable, however for any traffic sent over an open network (MelbourneWireless), SSH provides a suitable level of protection.
