Never use telnet

Logging into a system through telnet over an insecure network is just daft. Your password is there for any schmuck to see.

Always use ssh. There is also a free version called OpenSSH.

The major problem with ssh is access from windows platforms. There are several options for windows users:

• Win32 port of ssh.
• PuTTY, a native Win32 client that comes highly recommended
• A probably better, but commercial client called SecureCRT.
