SSH (Secure Shell) Version 1.2 Ssh (Secure Shell) is a program to securely log into another computer over an insecure network, to execute commands in a remote machine, and to move files from one machine to another. Its features include the following: 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 packets. o X11 connection forwarding provides secure X11 sessions. Automatically sets DISPLAY on remote host. 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 spoofing). o An authentication agent, running in the user's local workstation or laptop, can be used to hold the user's RSA authentication keys. o Multiple convenience features fix annoying problems with rlogin and rsh (such as returning correct exit status and running remote commands on a tty). o Complete replacement for rlogin, rsh, and rcp. Version 1.2 fixes many problems and adds new features. This version has been tested by many people and should be quite stable. Ssh is freely available, and may be used by anyone (see the file COPYING in the distribution for more details). There is no warranty of any kind, and patents may restrict your right to use this software in some countries. There is a mailing list for ssh. Send mail to ssh-request@clinet.fi to get instructions (or mail directly to majordomo@clinet.fi with "subscribe ssh" in body). The Ssh Home Page http://www.cs.hut.fi/ssh contains more information about the software, mailing lists, and archives. All official distributions of ssh are accompanied by a pgp signature by the key "pub 1024/DCB9AE01 1995/04/24 Ssh distribution key ".
