git ssh 代理设置

git_ssh_proxy.md

仅为 GitHub 设置代理

git 代理

设置 git config --global http.https://github.com.proxy socks5://127.0.0.1:1086
设置完成后, ~/.gitconfig 文件中会增加以下条目:

[http "https://github.com"]
    proxy = socks5://127.0.0.1:1086

ssh 代理

修改 ~/.ssh/config 文件

Host github.com
    User git
    ProxyCommand nc -v -x 127.0.0.1:1086 %h %p

在 Windows 下使用 ProxyCommand connect 设置现在 Powershell 中用 ssh 连接 git 失效，pull 和 push 都失败，命令

ssh -T git@github.com

返回错误：

CreateProcessW failed error:2
posix_spawnp: No such file or directory

但是使用 git bash 进行连接却是正常的，请问这是什么原因呢？以前这个设置在 Powershell 中也能用

如果 git 的 sh 命令在系统 PATH 里，通过下面的命令检测

PS > scoop which sh
~\scoop\apps\git\current\bin\sh.exe

PS > sh -l -c "which connect"
/mingw64/bin/connect

那么下面的配置在 Git Bash 和 PowerShell 里都可以工作

Host github.com
  HostName 	      ssh.github.com
  Port            443
  User            git
  IdentityFile    ~/.ssh/pri_gh
  # -H HTTP_PROXY, -S SOCK5_PROXY
  ProxyCommand    sh -c "connect -H 127.0.0.1:10802 %h %p"

Git Bash

$ ssh -T github.com
Hi <name>! You've successfully authenticated, but GitHub does not provide shell access.

$ ssh -T [email protected]
Hi <name>! You've successfully authenticated, but GitHub does not provide shell access.

PowerShell

> ssh -T github.com
Hi <name>! You've successfully authenticated, but GitHub does not provide shell access.

> ssh -T [email protected]
Hi <name>! You've successfully authenticated, but GitHub does not provide shell access.

补充Redhat 9环境下socks4代理用法 (使用V2RayA)

Host github.com
    User git
    ProxyCommand nc --proxy-type socks4 --proxy 127.0.0.1:20170 %h %p

检验

[vrqq@apm3 ~]$ ssh [email protected]
PTY allocation request failed on channel 0
Hi vrqq! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.
