Ack! Bad! Bad! Evil! Nasty!
As someone else has already pointed out (and I'm going to repeat, so the message gets across), telnet is BAD. Telnet sends *everything*, including those passwords you type, across the network in plaintext. Which means anyone with a packet sniffer can *easily* grab your root password and compromise your security.
SSH on the other hand, encrypts traffic from client to server and vice versa.
