OpenSSH client has a feature called "ControlMaster" that allows to reuse connections between multiple ssh sessions over a single network connection.
I was wondering if it was possible using x/crypto/ssh package of Golang to reuse a connection from a socket that has been created by the OpenSSH client with a command like:
ssh -M -f -N -o ControlPath=$HOME/.ssh/shared.sock myUsername@targetServerName
Is there any way to create a Golang Client from this $HOME/.ssh/shared.sock socket?
We usually use the Dial function to create the Client.
func Dial(network, addr string, config *ClientConfig) (*Client, error)
But I see there is as well the NewClient function that seems to be for reusing an existing connection.
func NewClient(c Conn, chans <-chan NewChannel, reqs <-chan *Request) *Client
I struggle to understand how I can instantiate the Conn and the two channels in a proper way.
Maybe it is not doable at all?
The aim is to be able to implement a kind of wrapper of the OpenSSH client and trigger commands using Golang before/after calling the actual OpenSSH client process. It would as well avoid having to reimplement the target host/port logic and the authentication.
