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 .
