Hi wangwen135! You've successfully authenticated, but GitHub does not provide shell access.
在用户目录新增config文件
$ vim ~/.ssh/config
内容如下:
# Add section below to it
Host github.com
Hostname ssh.github.com
Port 443
再测试一下:
$ ssh -T git@github.com
Hi xxxxx! You've successfully authenticated, but GitHub does not
