Connectivity Secure Shell

Starting a Tunnel

To start a tunnel from the Connectivity Secure Shell Management Console, you must first create a tunnel profile.

If you have created one or more tunnel profiles, you can start a Secure Shell tunnel by selecting a profile to open the tunnel according to the configuration settings saved in that profile. The Open Tunnel dialog box lists all of the tunnel profiles you have created.

Tip:  Applications that support Connectivity Secure Shell also let you configure and start tunnels. For more information, see the application-specific section in this Help.

After starting a tunnel, you can use it to carry any number of different communication protocols, provided they each use a single socket.

Note: 
  Most communication types that you initiate within the tunnel occur through their own channels. FTP is an example of a communication protocol that can use multiple connections.

If you start a tunnel to secure one connection, and then, using the same profile, attempt to start another tunnel to secure another connection, one of the following occurs:

  • The active tunnel is re-used. A new channel is created within this tunnel for each connection that uses same tunnel profile.
  • If you are using Connectivity Secure Shell or Exceed to start a tunnel, or if you enable X11 Port Forwarding when using another application such as HostExplorer, a new tunnel is created each time you create a connection using that profile.

To start a tunnel in Connectivity Secure Shell:

  1. In the Connectivity Secure Shell Management Console, open the Tunnels folder and click Connections. The three-paned Connection window is displayed.
  2. Click the Open Tunnel button in the top pane. The Open Tunnel dialog box opens.
  3. Select the tunnel profile you want to use to start the tunnel and click Open. The tunnel status is displayed in the top pane of the Secure Shell Management Console.
