7.4 SDT CONNECTOR: TELNET OR SSH CONNECT TO SERIALLY-ATTACHED DEVICES
SDT Connector can also be used to access text consoles on devices that are attached to the console server’s serial ports. For these
connections, configure the SDT Connector client software with a Service that will access the target gateway serial port, and then
set the gateway up as a host.
Launch SDT Connector on your PC.
Select Edit > Preferences.
Click Add.
Enter Serial Port 2 as the Service Name.
Click Add.
Select Telnet as the Client.
Enter 2002 as the TCP Port.
Click OK.
Close the Add Service window.
Close the SDTConnector Preferences window.
Assuming you have already set up the console server as a Gateway in your SDT Connector client (with username, password, etc.),
select this newly added Gateway and click the Host icon to create a host.
Alternatively, select File > New Host.
Enter 127.0.0.1 as the Host Address.
Optionally, add details in the Descriptive Name and Description/Notes fields.
Click OK.
Click the Serial Port 2 icon for Telnet access to the serial console on the device attached to serial port #2 on the gateway.
To enable SDT Connector to access to devices connected to the gateway’s serial ports, configure the console server to allow port
forwarded network access to itself, and enable access to the nominated serial port.
Navigate to Serial & Network > Serial Port.
Click Edit next to the selected Port.
For example, click Edit next to Port 2 if the target device is attached to the second serial port.
Ensure the port's serial configuration is appropriate for the attached device.
Set the Console Server Setting to Console Server Mode.
Click Apply.
Navigate to Serial & Network > Network Hosts.
Click Add Host.
In the IP Address/DNS Name field enter 127.0.0.1.
This is the loopback address.
Enter Loopback in the Description field.
Remove all entries under Permitted Services.
Select TCP.
Enter 200n in the Port field.
NOTE: “n” corresponds to the Serial Port selected in the step above. For Serial Port 2, for example, enter 2002.
