Everything was fine. Suddenly one day, an error was reported with git push :

WARNING: POSSIBLE DNS SPOOFING DETECTED!

The above errors are generally caused by the migration of the company’s Git warehouse, resulting in ip changes. There is a known_hostsfile in the git directory that stores the connected domain name and the corresponding ip. Every time there is a remote operation, it will verify whether the information in it matches, and the warehouse is migrated. known_hostsThe domain name and ip in the latter file must not match, so the above error will occur. The easiest way is to delete known_hoststhe domain name and the information behind it or empty the file.

: > ~/.ssh/known_hosts

Don’t forget the previous : number, and then re-verify the connection

ssh -T [email protected]

be accomplished!
