Enabling Ssh Remote Access - D-Link DFL-260E User Manual

2.1.4. The CLI
NetDefendOS for hostnames to be translated to IP addresses.
Serial Console CLI Access
The serial console port is a local RS-232 port on the NetDefend Firewall that allows direct access to
the NetDefendOS CLI through a serial connection to a PC or dumb terminal. To locate the serial
console port on D-Link hardware, see the D-Link Quick Start Guide .
To use the console port, the following equipment is required:
• A terminal or a computer with a serial port and the ability to emulate a terminal (such as using
the Hyper Terminal software included in some Microsoft Windows™ editions). The serial
console port uses the following default settings: 9600 bps, No parity, 8 data bits and 1 stop bit.
• A RS-232 cable with appropriate connectors. An appliance package includes a RS-232
null-modem cable.
To now connect a terminal to the console port, follow these steps:
1. Set the terminal protocol as described previously.
2. Connect one of the connectors of the RS-232 cable directly to the console port on the
NetDefend Firewall system.
3. Connect the other end of the cable to the terminal or the serial connector of the computer
running the communications software.
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.
Command-Line Interface
gw-world:/> add RemoteManagement RemoteMgmtSSH ssh Network=lannet
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
