PC:~$ ssh [email protected] 
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 [email protected] （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 [email protected]
