Some [SSH](https://en.wikipedia.org/wiki/Secure_Shell) options are worth
tweaking when directly distributing code with [git](https://git-scm.com/) to
multiple remotes.
[ConnectTimeout](https://www.man7.org/linux/man-pages/man5/ssh_config.5.html#:~:text=ConnectTimeout)
and
[BatchMode](https://www.man7.org/linux/man-pages/man5/ssh_config.5.html#:~:text=BatchMode)
(optionally for automation).
[ControlMaster](https://www.man7.org/linux/man-pages/man5/ssh_config.5.html#:~:text=ControlMaster)
enables multiplexing for session sharing via sockets.

```cfg { caption="An example ~/.ssh/config or /etc/ssh/ssh_config" }
ForwardX11 no
Compression no
ConnectTimeout 3
ServerAliveCountMax 1
ServerAliveInterval 10

Host *
  ControlMaster auto
  ControlPersist yes
  ControlPath ~/.ssh/sockets/%r@%h-%p
```

`%r@%h-%p`
[translates](https://www.man7.org/linux/man-pages/man5/ssh_config.5.html#TOKENS)
to `user@hostname-22`.
