Support for Control Master

[dwatley]

I noticed in the previous roadmap the Control Master feature was not going to be ready for the initial release. Any plans to support this in the future?

We have use cases for multiplexing ssh connections.

Its not in the horizon yet, unfortunately. It relies on a particular feature of Unix Domain sockets ( passing ancillary data ), that's not easy to realize in Windows.

Hi @manojampalam ,

Perhaps it's best to not use Unix Domain sockets (only available over WSL) and implement a simple communication over pipes.

In any case I hope you can implement it soon, as the VSCode Remote SSH uses this functionality.

Regards.

bump any status?

This is exactly the older #405
I also wish it was fixed/solved...

I've been migrating over from Putty/Kitty to OpenSSH on Windows 10. Just realized that this isn't supported yet. Here's my 👍 to adding ControlMaster support. Would love to see it.

I'm similar to mew1033, just migrated from PuTTY and multiplexing is the one feature that's preventing me from being able to drop PuTTY altogether.

[mew1033]

@lgretton This is definitely not multiplexing, but you can get sucky fake multiplexing using ProxyCommand. I did this:

Host myTunnel
    HostName iwantcontrol.master
    ForwardAgent yes
    DynamicForward 29123

Host crappymultiplexedhost
    HostName hostIWant
    ProxyCommand ncat --proxy-type socks5 --proxy localhost:29123 %h %p

It kinda sorta works. ¯\_(ツ)_/¯

Does MSFT still maintain this package? IMO it would be better for the team to upstream the changes. We are getting updates at a glacial pace and we still have many missing features.

[therealpxc]

Can we at least have the client report that the feature is not supported instead of printing opaque errors about sockets, as though the feature were implemented but happened to have suffered some incidental mishap?

[comio]

Connection multiplexing should be a must-to-have feature.
Can you increase the priority of this feature?

thanks a lot (and thanks to listen your community).

ciao

Just back for the yearly ping. Any updates on possibly bringing ControlMaster to powershell ssh?

Thanks!

about workaround with "ssh -O proxy". (I have not tried myself.)
