Running An Ssh Client - Nortel Secure Network Access Switch 4050 User Manual

774 Chapter 16 The Command Line Interface

Running an SSH client

Connecting to the Nortel SNAS 4050 using an SSH client is similar to connecting
using Telnet: the IP parameters on the Nortel SNAS 4050 must be configured in
advance, and SSH access must be enabled. After you provide a valid user name
and password, the CLI in the Nortel SNAS 4050 is accessible the same way as
when using a Telnet client. However, since a secured and encrypted
communication channel is set up even before the user name and password is
transmitted, all traffic sent over the network while configuring or collecting
information from the Nortel SNAS 4050 is encrypted. For information about
different user accounts and default passwords, see
SNAS 4050 cluster" on page
During the initial setup of the Nortel SNAS 4050 device or cluster, you are
provided with the choice to generate new SSH host keys. Nortel recommends that
you do so, in order to maintain a high level of security when connecting to the
Nortel SNAS 4050 using an SSH client. If you fear that your SSH host keys have
been compromised, you can create new host keys at any time by using the
/cfg/sys/adm/sshkeys/generate
Nortel SNAS 4050 after generating new host keys, your SSH client will display a
warning that the host identification (or host keys) has changed.
