github ssh被屏蔽的解决方案

发现今天开始github的ssh都被屏蔽了，导致git命令没法用，之前只是屏蔽了https而已，唉。

检查是否有安装connect

$bash: connect
connect --- simple relaying command via proxy.
Version 1.101
usage: connect [-dnhst45] [-p local-port][-R resolve] [-w timeout]
          [-H proxy-server[:port]] [-S [user@]socks-server[:port]]
          [-T proxy-server[:port]]
          [-c telnet-proxy-command]
          host port

如提示没有则进行安装

sudo apt update -y
sudo apt install connect-proxy

如果update后install还是提示找不到connect-proxy包，检查系统软件源

vim /etc/apt/sources.list

若没有可使用清华或阿里云之类的镜像，复制内容写入即可

创建ssh配置文件

vim ~/.ssh/config

配置文件中写入以下内容，ProxyCommand 中的代理地址 localhost:1080 根据实际情况修改

Host github.com
        User [email protected]
        Port 22
        HostName github.com
        IdentityFile "~/.ssh/id_rsa"
        TCPKeepAlive yes
        ProxyCommand connect -S localhost:1080 -a none %h %p

Host ssh.github.com
        User [email protected]
        Port 443
        HostName ssh.github.com
        IdentityFile "~/.ssh/id_rsa"
        TCPKeepAlive yes
        ProxyCommand connect -S localhost:1080 -a none %h %p

开启代理，git pull一下，完毕。

windows用户的IdentityFile可能位于 C:/Users/<用户名>/.ssh/id_rsa

wsl2用户可以用cat /etc/resolv.conf |grep "nameserver" |cut -f 2 -d " "获取windows主机ip配置代理。
