SSH TUNNELS & SDT CONNECTOR
Each Opengear console server has an embedded SSH server and uses SSH tunneling so remote users can
securely connect through the console server to managed devices - using text-based console tools (such
as SSH, Telnet, SoL) or graphical tools (like VNC, RDP, HTTPS, HTTP, X11, VMware, DRAC, iLO).
The managed devices being accessed can be located on the same local network as the console server or
they can be attached to the console server via a serial port. The remote user connects to the console
server thru an SSH tunnel via dial-up, wireless or ISDN modem; a broadband Internet connection; the
enterprise VPN network or the local network:
To set up the secure SSH tunnel from the Client PC to the console server, you must install and launch SSH
client software on the user’s PC. Opengear recommends you use the SDT Connector client software that
is supplied with the console server for this. SDT Connector is easy to install and auto-configure and it
provides all your users with point-and-click access to all the systems and devices in the secure network.
SDT Connector sets up a secure SSH tunnel from the client to the selected console server, establishes a
port forward connection to the target network connected host or serial connected device, and executes
the client application that is used in communicating with the host.
