Using SDTConnector to access serially connected devices
While PuTTY and SSHterm can be used for Telnet or SSH access to devices that are serially attached to the Opengear console server, SDTConnector provides a simpler alternative.
To enable SDTConnector to access to devices connected to the gateway's serial ports, you must enable access to the nominated serial port on the console server, then configure it to allow port forwarded network access to itself:
- Browse to the console server Management Console
- Select Serial Port from Serial & Network and click Edit next 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, then 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 Opengear'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.
Next you must configure SDTConnector with a Service that will access the target gateway serial port, and then set the gateway up as a host. This can be autoconfigured (as detailed in faq285) or configured manually:
- Launch SDTConnector on your PC.
- Select Edit -> Preferences
- Click the Services tab and 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
- Select Close and Close again.
- Set up the console server as a Gateway in your SDTConnector client (with username/ password etc as detailed in faq266)
- 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 and select Serial Port 2 for Service. In Descriptive Name, enter something along the lines of Loopback ports, or Local serial ports
- Click OK.
Now you can click Serial Port 2 icon for Telnet access to the serial console on the device attached to serial port #2 on the gateway.
