Establishing a Telnet connection

A Telnet connection offers the convenience of accessing the Nortel SNAS
cluster from any workstation connected to the network. Telnet access
provides the same options for user access and administrator access as
those available through the console port.

When you use a Telnet connection to access the Nortel SNAS from a
workstation connected to the network, the communication channel is not
secure. All data flowing back and forth between the Telnet client and the
Nortel SNAS is sent unencrypted (including the password), and there is no
server host authentication.

To configure the Nortel SNAS cluster for Telnet access, you need to have
a device with Telnet client software located on the same network as the
Nortel SNAS device or cluster. The Nortel SNAS must have a RIP and a
MIP. If you have already performed the initial setup by selecting

new

or

join

in the Setup menu, the assignment of IP addresses is complete.

When you are making configuration changes to a cluster of Nortel SNAS
devices using Telnet, Nortel recommends that you connect to the MIP.
However, if you want to halt or reboot a particular Nortel SNAS in a
cluster, or reset all configuration to the factory default settings, you must
connect to the RIP (the IP address of the particular Nortel SNAS device).
To view the IP addresses of all Nortel SNAS devices in a cluster, use the

/info/contlist

command.

ATTENTION

Telnet/ssh will be enabled on RIP & MIP.

Enabling and restricting Telnet access

Telnet access to the Nortel SNAS cluster is disabled by default, for
security reasons. However, depending on the severity of your security
policy, you may want to enable Telnet access. You may also restrict Telnet
access to one or more specific machines.
