Description akostadinov 2009-06-13 18:16:01 AEST

Hallo,

currently if one uses ControlMaster auto, then things work fine but one is not able to use port forwarding and other features on subsequent connections.

For example if one first opens a ssh connection to a host, then tries a command like "vncviewer -via host :1", then that fails badly. Adding command line options in this case is cumbersome.

So my suggestion is when "ControlMaster auto" is selected then in case of subsequent connection to the same host multiplexing to get disabled if client is requesting features that will not be available when using multiplexing.

So if
1. ssh host
2. ssh host # in another terminal
multiplexing should be enabled

But if
1. ssh host
2. ssh -L ##:xxx:## host #in another terminal
multiplexing should not be used for the second invocation

Hope this makes sense.

Regards

Yes, this has been on my todo for some time. Put it on the list for 5.4.
