解决ssh-connect-to-host-github-com-port-22-connection-timed-out

PC:~$ ssh git@github.com
ssh: connect to host github.com port 22: Connection timed out

解决办法:(linux下)

~$ cd ~

~$ cd .ssh/

~$ touch config

在.ssh目录下创建一个config文件,输入如下内容:

Host github.com
User xxx@163.com (你注册github时的邮箱,这里使用注册的用户名也行)
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443
可以把以上内容拷到config文件里面,注意修改你的邮箱,保存并关闭
进行测试是否连接上github.com
PC:~/.sshcd PC: ssh -T git@github.com
