Git says "Warning: Permanently added to the list of known hosts"

Question

Every time I use git to interact with a remote, such as when pulling or pushing, I am shown the following message:

Warning: Permanently added '...' (RSA) to the list of known hosts.

How can I prevent this annoying message from displaying? It is only an annoyance—everything functions properly.

Answer 1

Solution: create a ~/.ssh/config file and insert the line:

UserKnownHostsFile ~/.ssh/known_hosts

You will then see the message the next time you access Github, but after that you'll not see it anymore because the host is added to the known_hosts file. This fixes the issue, rather than just hiding the log message.

This problem was bugging me for quite some time. The problem occurs because the OpenSSH client compiled for Windows doesn't check the known_hosts file in ~/.ssh/known_hosts
