Accessing the Cisco Security Appliance with Secure Shell
Secure Shell (SSH) is an application that runs over Transmission Control Protocol (TCP).
SSH provides strong authentication and encryption capabilities. Cisco Security Appliances
supports the SSH remote shell functionality provided in SSH version 1. SSH version 1 also
works with Cisco IOS Software devices. Up to five SSH clients are allowed simultaneous
access to the PIX Firewall console.
NOTE If you do not specify the interface name, the telnet command adds command
statements to the configuration to let the host or network access the Telnet management
session from all internal interfaces.
NOTE The passwd command can be used interchangeably with the password command.
