DI-1162/DI-1162M Remote Access Router
117
Using Telnet
The DI-1162/DI-1162M router can be configured and managed using telnet. Telnet accesses the same built-in
configuration program as the RS-232 Diagnostic port console connection. As such, all settings that can be adjusted
through the console can also be configured using Telnet.
Telnet Configuration
In order to use telnet, the DI-1162/DI-1162M router must first be configured using a console connected to the RS-
232 Diagnostic port. Depending on the placement of the management station using telnet, the initial configuration
requirements for the router are as follows:
Using Telnet via LAN
Preparing the router for management by telnet over the LAN only requires enabling the LAN port, enabling telnet,
and assigning the LAN port an IP address. To do this:
1.
Connect a console to the RS-232 Diagnostic port on the front panel of the router and run a terminal emulation
program (for more information, see
Connecting the Console to the Router
and
Setting Up the Console
sections
of this manual).
2.
Enable the LAN port in the
Interface Configuration
submenu.
3.
Assign an IP address to the LAN port in the
Network Configuration
submenu.
4.
Enable Telnet in the
Advanced Functions
submenu.
5.
Connect the router to the LAN.
The router can now be accessed via the LAN by the included Windows-based Configuration program, Telnet and
SNMP management applications. For more detailed information regarding these procedures, please refer to the
Connecting the Router
section of this manual. For more information about the submenus, please refer to the
Configuration and Management
section of this manual.
Using Telnet via WAN
Preparing the router for management by telnet over WAN lines requires more initial configuring of the router via
the console.
To do this, you must configure a WAN port for dial-in users. Please refer to
Step 3b - Configuring the WAN Ports
for Dial-in, Dial-out and Leased Lines
section on page 10 of this manual.
System Timeout
When you are connected to your DI-1162/DI-1162M via Telnet, there is a system timeout (in the
System
Information
submenu), adjustable to a maximum of 90 minutes. If you are logged onto the device and leave it
inactive for this timeout period, the router will automatically disconnect you.
Using RADIUS Authentication
In addition to the dial-in user list, which can hold up to eight users, this model also supports an external
authentication server which may provide password storage and usage accounting for thousands of users.
