SDT Connector - Telnet or SSH Serial Device Connection

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, you must 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 computer. Select Edit: Preferences and click the Services tab. Click Add
• Enter "Serial Port 2" in Service Name and click Add
• Select Telnet client as the Client. Enter 2002 in TCP Port. Click OK, then Close and Close again
• Assuming you have already set up the target Console Server as a gateway in your SDT Connector client (with username/
password etc), select this gateway and click the Host icon to create a host. Alternatively, select File: New Host.
• Enter 127.0.0.1 as the Host Address and select Serial Port 2 for Service. In Descriptive Name, enter something along
the lines of Loopback ports, or Local serial ports. Click OK.
• Click 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, you must also configure the Console
Server itself to allow port forwarded network access to itself, and enable access to the nominated serial port:
• Browse to the Console Server and select Serial Port from Serial & Network
• Click Edit to selected Port # (e.g. 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
• Scroll down to Console Server Setting and select Console Server Mode. Check Telnet (or SSH) and scroll to the bottom
and click Apply
• Select Network Hosts from Serial & Network and click Add Host
• In the IP Address/DNS Name field, enter 127.0.0.1 (this is the Console Server's network loopback address) and enter
Loopback in Description
• Remove all entries under Permitted Services and select TCP and enter 200n in Port. (This configures the Telnet port
enabled in the previous step, so for Port 2 you would enter 2002)
• Click Add then scroll to the bottom and click Apply
• Administrators by default have gateway and serial port access privileges; however for Users to access the gateway and the
serial port, you will need to give those Users the required access privileges. Select Users & Groups from Serial & Network.
Click Add User. Enter a Username, Description and Password/Confirm. Select 127.0.0.1 from Accessible Host(s) and
select Port 2 from Accessible Port(s). Click Apply.
