Git Pull/Git Push配置SSH代理

当git pull或push时经常会遇到Could not read from remote repository的报错，尤其是在启用Clash等代理软件后

# git push
kex_exchange_identification: Connection closed by remote host
Connection closed by 20.205.243.166 port 22
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

此时我们可以通过配置SSH代理来保障网络通畅，添加~/.ssh/config文件，配置如下内容

# cat ~/.ssh/config
Host github.com
    User git
    Hostname github.com
    Port 22
    ProxyCommand nc -v -x localhost:7890 %h %p

ProxyCommand依赖nc，服务器上需要提前安装nc

# apt-get install ncat
