我有一个相对完整的设置~/.ssh/config。这就是最重要的：
Host *
ControlMaster auto
ControlPath /tmp/ssh_mux_%h_%p_%r
ControlPersist 24h
BatchMode yes
Ciphers blowfish-cbc
Compression yes
VisualHostKey yes
我想让它等ControlMaster不适用于github; 他们显然主动断开这些持久的联系，这是我理解和尊重的。
所以要明确：
$ rm /tmp/ssh_mux_*
$ ssh git@github.com
PTY allocation request failed
Hi frioux! You've successfully authenticated, but GitHub does not provide shell access.
Shared connection to github.com closed.
$ ls /tmp/ssh_mux_*
/tmp/ssh_mux_github.com_22_git
所以我读了一些文档，我在IRC中问过，这就是我最终的结果：
Host !github.com
ControlMaster auto
ControlPath /tmp/ssh_mux_%h_%p_%r
ControlPersist 24h
Host *
BatchMode yes
Ciphers blowfish-cbc
Compression yes
VisualHostKey yes
所以现在github正确地不使用ControlMaster：
$ rm /tmp/ssh_mux_*
$ ssh git@github.com
Host key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48

Hi frioux! You've successfully authenticated, but GitHub does not provide shell access.

$ ls /tmp/ssh_mux_*
但其他任何事情都没有：
$ rm /tmp/ssh_mux_*
$ ssh cs ls

我尝试制作主机线Host !github.com, *，Host *, !github.com但据我所知，它总是适用于github。
我怎么能做我想做的事？
