Introducing SSH (Secure Shell) Version 1.0
Ssh (Secure Shell) is a program to log into another computer over a
network, to execute commands in a remote machine, and to move files
from one machine to another. It provides strong authentication and
secure communications over insecure channels. Its features include
o Strong authentication. Closes several security holes (e.g., IP,
routing, and DNS spoofing and listening for passwords from the
network). New authentication methods: .rhosts together with
RSA based host authentication, and pure RSA authentication.
o All communications are automatically and transparently
encrypted. Encryption is also used to protect against spoofed
o X11 connection forwarding provides secure X11 sessions.
o Arbitrary TCP/IP ports can be redirected over the encrypted
channel in both directions.
o Client RSA-authenticates the server machine in the beginning of
every connection to prevent trojan horses (by routing or DNS
spoofing) and man-in-the-middle attacks, and the server RSA-
authenticates the client machine before accepting .rhosts or
/etc/hosts.equiv authentication (to prevent DNS, routing, or IP
o An authentication agent, running in the user's local workstation
or laptop, can be used to hold the user's RSA authentication
o Multiple convenience features fix annoying problems with rlogin
o Complete replacement for rlogin, rsh, and rcp.
Ssh is freely available, and may be used by anyone (see the file
