Nortel Networks 4050 manual Running an SSH client

774Chapter 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 “Accessing the Nortel SNAS 4050 cluster” on page 775.

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 command. When reconnecting to the Nortel SNAS 4050 after generating new host keys, your SSH client will display a warning that the host identification (or host keys) has changed.
