What is SSH?
SSH is a tool for secure remote login over insecure networks. It provides
an encrypted terminal session with strong authentication of both the
server and client, using public-key cryptography. Features include:
SSH is based on IETF standard protocols.
- a variety of user authentication methods
- tunneling arbitrary TCP connections through the SSH session, protecting
normally insecure protocols such as IMAP and allowing secure passage
- automatic forwarding of X windows connections
- support for external authentication methods, including Kerberos and
- secure file transfers
