Notes on SSH usage

If you want to use Gogs with SSH and be able to pull/push with you SSH key, your SSH daemon must be properly configured to use private/public keys. Here is a sample configuration of /etc/ssh/sshd_config that works with Gogs:

PubkeyAuthentication yes
AuthorizedKeysFile %h/.ssh/authorized_keys
ChallengeResponseAuthentication no
PasswordAuthentication no
UsePAM no

You also need to add your public key to your Gogs profile.

If you use SSH on another port than 22, you need to add theses lines to your ssh config in ~/.ssh/config:

Host domain.tld
    port 2222 # change this with the port you use

Private Mode

Actually it's possible to access to the Git repositories by the git command over HTTP also in private mode installation. It's important to know that in this mode the repository could be ALSO getted if you don't set the repository as private in the repos settings.
