SDT Connector enables a secure management connection to a remote Host to be set up by simply pointing at the Host, then clicking the Service/Application that will be used to access that Host. This automatically:
- establishes an SSH tunnel to the remote console server
- redirects all the appropriate TCP/UDP ports through to the Host, and
- launches the appropriate local client application (e.g. Firefox/IE browser for a HHTP/HTTPS service) pointing at the endpoint of the redirection
It is simple to create new secure SSH tunnel pathways to a new console server. On the SDTConnector client:
- select New Gateway
- enter the IP or DNS Address of the console server gateway, and the SSH port that will be used (typically 22)
- enter the Username and Password of a user on the gateway that is able to connect via SSH and create SSH port redirections
Also once the new console server gateway has been added you can then use Retrieve Hosts to automatically add all the configured Hosts to SDTConnector (refer faq285).
In theory SDTConnector can be configured to access hundreds of console server gateways, so multiple remote sites can be managed from the one location. At each site the console server(s) there can be configured to port forward to hundreds of locally networked Hosts. And there is no limit on the number of Host connections that an SDTConnector client can concurrently have open through the one tunnel. Similarly hundreds of SDTConnector clients can be configured to access the one console server.
So SDTConnector could on its own be used to manage access for the very largest and most distributed of operations. However there are some practical limits:
- Firstly SDTConnector is by design a light weight access client which presents a very "flat" view of the operation being managed. For more complex operations, Opengear provides a more sophisticated central management solution
- There's also some hard limits on the number of SDTConnector SSH tunnels that can be open at the one time on any particular Opengear console server (ACM5000, ACM5500, IM4200 and CM4000 devices each support at least 50 such concurrent connections)
