How to interact with ssh-agent?

[eyalk5]

Summary of the new feature / enhancement

It is a question-suggestion. I want to use it from git-bash. Right now , the ssh-agent service doesn't listen on any address or exposes SSH_AUTH_SOCK variable. So, git (by git bash) or the associate ssh can't find it. I tried providing it with -a , didn't work.
Tried to make it log using sshd_config, didn't work.

Even in the registry
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\OpenSSH\Agent
it doesn't specify any socket. No handles. Couldn't find a way to work with it!

Proposed technical implementation details (optional)

Many options. Just make it work! (or document it please)

On windows it's not a socket, it's a named pipe, and its hardcoded to \.\pipe\openssh-ssh-agent

The SSH client on windows searches for this pipe name by default, but SSH_AUTH_SOCK can be set if you want it to use a different agent with a different pipe name.

Also git for windows won't use it because it includes its own ssh client. You have to set GIT_SSH_COMMAND to use the windows built in (or other) ssh client instead of its own.
