The Command Line Interface
For more information on how to enable Telnet access, see the
/cfg/sys/adm/telnet
command (see
). For
more information on how to restrict Telnet access to one or more specific
machines, see
“Configuring the Access List” (page 273)
.
Running Telnet
Once the IP parameters on the Nortel SNAS 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, run the Telnet
program on your workstation and issue the Telnet command, followed by
the IP address of the Nortel SNAS.
telnet
<IP address>
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 cluster” (page 381)
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
Enabling and restricting SSH access
SSH access to the Nortel SNAS 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
). For
more information on how to restrict SSH access to one or more specific
machines, see
“Configuring the Access List” (page 273)
.
Running an SSH client
Connecting to the Nortel SNAS using an SSH client is similar to
connecting using Telnet: the IP parameters on the Nortel SNAS 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
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
Nortel Secure Network Access Switch
