问题

安装GIT并完成公钥验证：Linux 系统拉取 Github项目

[root@xxx devtools]# ssh -T git@github.com
ssh: connect to host github.com port 22: Connection timed out

解决方案

进入在存放公钥私钥id_rsa.pub文件里，新建/修改config文本

[root@xxx myblog]# cd ~/.ssh
[root@xxx]# vim config

config中的内容如下：

Host github.com
User zhengzhaojava@163.com
Hostname ssh.github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
Port 443

重新验证成功

[root@xxx]# ssh -T git@github.com

Hi ProgrammerAdvanced! You've successfully authenticated, but GitHub does not provide shell access.
