Engity's Bifröst

Welcome

Bifröst (spoken as "Bee-frest"), is a highly customizable SSH server with several ways to authorize a user and where and how to execute its session. It can be used as a drop-in-replacement for OpenSSH's sshd, but it was actually created with some more advanced stuff in mind; see below.

Features

SSH protocol compliant

Fully SSH protocol compliant server, like you would expect.

OpenID Connect

You can connect via your SSH keys, as usually. And so on...

...but you can also use OpenID Connect (or OAuth2) identity provider. The best thing about it: In contrast to the other SSH servers with OpenID Connect you don't need to install another client in addition to your regular SSH Client (OpenSSH, PuTTy, ...).

Remember me

Once authenticated using a public key, Bifröst can (temporarily) store that public key for faster reconnection while the session is still active.

Automatic user provisioning

If a user needs to be authorized in a local environment using OpenID Connect, Bifröst can automatically create a local user based on a pre-defined requirement template.

Bifröst can also automatically clean up these local users once they are no longer needed. For example: If their session times out after a defined idle-time, the local user, their home directory, and all running processes can be cleaned up.
