When a channel is created with a port forwarding rule, it is
displayed in the Channels list of the Tunneling bar. You are
able to view all channels created and terminate unnecessary
channels for the currently open session in the Tunneling bar.
In the View menu, click Tunneling Bar.
RESULT: The Tunneling bar appears on
the bottom of the Xshell window.
Click the Channels tab.
In the Channels list, right-click on the channel you
want to terminate.
In the menu, click Terminate. Note: The channels are terminated automatically when the
connection is closed. You need to terminate a channel explicitly
only when it is blocked or does not work properly.
