如何將某些設定套用至 ssh 主機而不包括其他主機？

如何將某些設定套用至 ssh 主機而不包括其他主機？

我的~/.ssh/config.這是頂部的內容：

Host *
   ControlMaster auto
   ControlPath /tmp/ssh_mux_%h_%p_%r
   ControlPersist 24h
   BatchMode yes
   Ciphers blowfish-cbc
   Compression yes
   VisualHostKey yes

我想讓ControlMasteretc不適用於github；他們顯然主動斷開了這些持久的聯繫，我理解並尊重這一點。

所以要明確的是：

 $ rm /tmp/ssh_mux_*
 $ ssh [email protected]
   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

所以我讀了一些文檔，在 IRC 中詢問，這就是我最終得到的結果：

Host !github.com
   ControlMaster auto
   ControlPath /tmp/ssh_mux_%h_%p_%r
   ControlPersist 24h

Host *
   BatchMode yes
   Ciphers blowfish-cbc
   Compression yes
   VisualHostKey yes

所以現在github正確地不使用ControlMaster：

 $ rm /tmp/ssh_mux_*
 $ ssh [email protected]
   Host key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48
   +--[ RSA 2048]----+

   |       + .       |
   |      . B .      |
   |     o * +       |
   |    X * S        |
   |   + O o . .     |
   |    .   E . o    |
   |       . . o     |
   |        . .      |
   +-----------------+

   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_*

但其他也沒有：

 $ rm /tmp/ssh_mux_*
 $ ssh cs ls
   Host key fingerprint is 89:d1:40:7f:0d:11:28:10:ce:23:e6:a9:12:9d:a1:5b

   |  + + ..o . .    |
   | = = . o o       |
   |o E   . S        |
   | =               |
   |+                |
   |.                |
   |                 |
   +-----------------+

   /home/frew
   bin
   code
   irclogs
   lib
   out
   test

 $ ls /tmp/ssh_mux_*

我嘗試製作主機線Host !github.com, *，Host *, !github.com但據我所知，當我這樣做時，它總是適用於 github。

我怎樣才能做我想做的事？

答案1

之後的模式Host用空格而不是逗號分隔，所以這應該有效：

Host * !github.com
    ControlMaster auto
    ControlPath /tmp/ssh_mux_%h_%p_%r
    ControlPersist 24h

答案2

IRC 上的 rudi_s 幫助我想出了解決方案：

Host github.com
   ControlMaster  no
   ControlPath    no
   ControlPersist no

Host *
   ControlMaster auto
   ControlPath /tmp/ssh_mux_%h_%p_%r
   ControlPersist 24h
   BatchMode yes
   Ciphers blowfish-cbc
   Compression yes
   VisualHostKey yes
