问题描述

正常配置并使用使用SSH方式，使用以下命令git clone、git pull、git push，报错如下：

bash 复制代码

ssh: connect to host github.com port 22: connection timed out
fatal: could not read from remote repository.

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

原因分析：

表明SSH连接在尝试通过22端口连接到远程服务器时超时。这可能是由于网络环境、防火墙设置或代理配置等原因导致的（很可能端口22被防火墙或提供商阻止了）。

解决方案：

bash 复制代码

$ git clone [email protected]:xxxxx/xxxx.git my-awesome-proj
Cloning into 'my-awesome-proj'...
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.

$ # This should also timeout
$ ssh -T [email protected]
ssh: connect to host github.com port 22: Connection timed out

$ # but this might work
$ ssh -T -p 443 [email protected]
Hi xxxx! You've successfully authenticated, but GitHub does not provide shell access.

$ # Override SSH settings

$ vim ~/.ssh/config

# Add section below to it
Host github.com
  Hostname ssh.github.com
  Port 443
  
$ ssh -T [email protected]
Hi xxxxx! You've successfully authenticated, but GitHub does not
