  • 这个大概是公司网络把访问出去22端口给屏蔽了，我telnet也不通。

解决方案

  • GitHub允许使用443端口，下面改成走443端口。
  • 先检查走443端口能否行得通。
ssh -T -p 443 git@ssh.github.com
  • 确认有successful提示，如下。
 The authenticity of host '[ssh.github.com]:443 ([20.205.243.160]:443)' can't be established.
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '[ssh.github.com]:443' (ED25519) to the list of known hosts.
Hi 1030907690! You've successfully authenticated, but GitHub does not provide shell access.

vim ~/.ssh/config
