I have the following entry in my
Host AAA User BBB HostName CCC ControlMaster auto ControlPath ~/.ssh/%r@%h:%p
The above allows me to multiplex multiple ssh sessions through the same ssh connection without having to type in the password every time I need a new session (as long as the master connection remains open).
However, I have noticed that once I have a relatively high # of connections multiplexed (~7), I can't add more sessions to the same multiplexed connection, and I start get the following error:
> ssh -X AAA mux_client_request_session: session request failed: Session open refused by peer Password:
Why am I getting this error? Is there a limit in the # of ssh sessions I can multiplex in the same connection? Can I change that limit? Would that be a bad idea?
