I'd like to change the default SSH2 port in Eclipse from 22 to another one. I try to define the host like host:55 (if using 55 for SSH2) and no luck.
After you have created your connection, go to the Remote Systems Explorer(Window->Views->Remote Systems) right click on any one of the child items of the connection and select Properties. In the properties window select the Subsystem group. The port can be configured from this screen.
