ssh:connect to host github.com port 22: Connection timed out报错解决方法

换为443端口

操作方法：

1.进入~/.ssh下

cd ~/.ssh

2.创建一个config文件

vim config

3.编辑文件内容：

??? Host github.com
??? User git
??? Hostname ssh.github.com
??? PreferredAuthentications publickey
??? IdentityFile ~/.ssh/id_rsa
??? Port 443
??? ?
??? Host gitlab.com
??? Hostname altssh.gitlab.com
??? User git
??? Port 443
??? PreferredAuthentications publickey
??? IdentityFile ~/.ssh/id_rsa

4.检查是否成功

ssh -T git@github.com
