Nortel Secure Network Access Switch 4050 User Guide

Running Telnet

Once the IP parameters on the Nortel SNAS 4050 are configured and Telnet

access is enabled, you can access the CLI using a Telnet connection. To establish a

Telnet connection with the Nortel SNAS 4050, run the Telnet program on your

workstation and issue the Telnet command, followed by the IP address of the

Nortel SNAS 4050.

You will then be prompted to enter a valid user name and password. For more

information about different user accounts and default passwords, see “Accessing

the Nortel SNAS 4050 cluster” on page 775.

Establishing a connection using SSH

Using an SSH client to establish a connection over the network provides the

following security benefits:

• server host authentication

• encryption of passwords for user authentication

• encryption of all traffic that is transmitted over the network when configuring

or collecting information from the Nortel SNAS 4050

Enabling and restricting SSH access

SSH access to the Nortel SNAS 4050 is disabled by default. However, depending

on the severity of your security policy, you may want to enable SSH access. You

may also restrict SSH access to one or more specific machines.

For more information on how to enable SSH access, see the

/cfg/sys/adm/ssh

command (see page 484). For more information on how to restrict SSH access to

one or more specific machines, see “Configuring the Access List using the CLI”

on page 474.
