openssh unix dev - Jul 2014 - Does openssh supports multi-channeling ?

Hi All,

In openssh, do we support multi-channeling?
Rather than opening a new TCP socket for each SSH connection, all the SSH
connections are multiplexed into one TCP connection.

If so, from which version , do openssh supports it?

Thanks

Yes, since 4.4, if I recall correctly. See ControlMaster and
ControlPath in ssh_config(5).

Hi,

it looks like this had its 10th anniversary last month:

djm at cvs.openbsd.org 2004/06/13 15:03:02
         [channels.c channels.h clientloop.c clientloop.h includes.h readconf.c]
         [readconf.h scp.1 sftp.1 ssh.1 ssh.c ssh_config.5]
         implement session multiplexing in the client (the server has supported
         this since 2.0); ok markus@
