Secure Shell
Secure Shell (SSH) is way to defended TCP/IP advice sessions by
encrypting the data.With the encryption, neither the passwords nor the abstracts are
sent in bright text. SSH is not bound to the PIX but is acclimated in a array of ways,
such as X.11 connections. SSH is advised to be a backup for rlogin, rsh,
and rcp, which are afraid protocols. For this discussion, we use SSH as the preferred
method to affix to a Cisco PIX firewall instead of application the traditional
Telnet method.
NOTE
The Cisco PIX firewall provides alone the server basic of SSH. A PIX
cannot be an SSH applicant to addition SSH server.
Whether you use Windows, UNIX, Linux, or Mac OS as your operating
system, abounding SSH audience are available. For Windows, one of the best popular
free audience is Tera Term with SSH extensions. For UNIX and Linux there is
OpenSSH, and for the Mac there is NiftyTelnet.The examples that chase use
Tera Term on a Windows platform.
NOTE
The PIX firewall alone supports SSH adaptation 1, not SSH adaptation 2.
