2.1.4. The CLI
4. Press the enter key on the terminal. The NetDefendOS login prompt should appear on the
terminal screen.
SSH (Secure Shell) CLI Access
The SSH (Secure Shell) protocol can be used to access the CLI over the network from a remote
host. SSH is a protocol primarily used for secure communication over insecure networks, providing
strong authentication and data integrity. SSH clients are freely available for almost all hardware
platforms.
NetDefendOS supports version 1, 1.5 and 2 of the SSH protocol. SSH access is regulated by the
remote management policy in NetDefendOS, and is disabled by default.
Example 2.2. Enabling SSH Remote Access
This example shows how to enable remote SSH access from the lannet network through the lan interface by
adding a rule to the remote management policy.
CLI
gw-world:/> add RemoteManagement RemoteMgmtSSH ssh Network=lannet Interface=lan
Web Interface
1. Go to System > Remote Management > Add > Secure Shell Management
2. Enter a Name for the SSH remote management policy, for example ssh_policy
3. Select the following from the dropdown lists:
• User Database: AdminUsers
• Interface: lan
• Network: lannet
4. Click OK
Logging on to the CLI
When access to the CLI has been established to NetDefendOS through the serial console or an SSH
client, the administrator will need to logon to the system before being able to execute any CLI
command. This authentication step is needed to ensure that only trusted users can access the system,
as well as providing user information for auditing.
When accessing the CLI remotely through SSH, NetDefendOS will respond with a login prompt.
Enter your username and press the Enter key, followed by your password and then Enter again.
After a successful logon, the CLI command prompt will appear:
gw-world:/>
If a welcome message has been set then it will be displayed directly after the logon. For security
reasons, it is advisable to either disable or anonymize the CLI welcome message.
Changing the admin User Password
It is recommended to change the default password of the admin account from admin to something
LocalUserDatabase=AdminUsers
