The purpose of this command is typically to test or use the SSH connection to GitHub, especially when the default port 22 is blocked or for some reason unavailable.

By using port 443, the connection can bypass firewalls that only allow HTTPS traffic, which is useful in restrictive network environments.

git config --global "url.ssh://git@ssh.github.com:443/.insteadOf" git@github.com

Not worked. It reports the following error after I set the config:

git pull 致命错误：远程错误： is not a valid repository name Visit https://support.github.com/ for help

git config --global "url.ssh://git@ssh.github.com:443/.insteadOf" git@github.com:

seem to miss a colon

添加如下配置到 ~/.ssh/config
Host ssh.github.com
HostName ssh.github.com
User git
PreferredAuthentications publickey
IdentityFile YOUR_RSA_PATH
Port 443

并且添加如下配置到 ~/.gitconfig
[url "git@ssh.github.com:"]
insteadOf = git@github.com:

thanks!

可行！！

Thanks!

Niubility!

Thanks!

suggest using url..insteadOf setting instead of overriding the connection for github.com in ~/.ssh/config (that's what the documentation describes), like so:

git config --global "url.ssh://git@ssh.github.com:443/.insteadOf" git@github.com:
