Configuring Usernames; Ssh Protocol Support - Avaya G250 Administration

Accessing the Avaya G250/G350 Media Gateway
The G250/G350 provides the following three privilege levels:
Read-only — You can use Read-only privilege level to view configuration parameters.
●
Read-write — You can use Read-write privilege level to view and change all configuration
●
parameters except those related to security. For example, you cannot change a password
with Read-write privilege level.
Admin — You can use Admin privilege level to view and change all configuration
●
parameters, including parameters related to security. Use Admin privilege level only when
you need to change configuration that is related to security, such as adding new user
accounts and setting the device policy manager source.
The default username has Admin privilege level. For security reasons, the network
administrator usually changes the password of the default username. For more information
about privilege levels, see Avaya G250 and Avaya G350 CLI Reference, 03-300437.

Configuring usernames

To create a username, use the username command. To remove a username, use the no
username command. To change the password or the privilege level for a username, remove
the username and add it again. You need an Admin privilege level to use the username and no
username commands.
When you create a new user, you must define the user's password and privilege level. The
following example creates a user named John with the password johnny and a Read-write
privilege level:
G350-001(super)#

SSH protocol support

Secure Shell (SSH) protocol is a security protocol that enables you to establish a remote
session over a secured tunnel, also called a remote shell. SSH accomplishes this by creating a
transparent, encrypted channel between the local and remote devices. In addition to the remote
shell, SSH provides secure file transfer between the local and remote devices. SSH is used for
telnet file transfers. The G250/G350 supports two concurrent SSH users.
There are two ways to establish an SSH session:
RSA authentication
●
Password authentication
●
Use the show ip ssh command to determine which of these ways is used on your G250/
G350. See SSH Configuration
