teleport

"Gravitational Teleport is a modern SSH server for remotely accessing clusters of Linux servers via SSH or HTTPS. It is intended to be used instead of sshd.  Teleport enables teams to easily adopt the best SSH practices like:

• No need to distribute keys: Teleport uses certificate-based access with automatic expiration time.
• Enforcement of 2nd factor authentication.
• Cluster introspection: every Teleport node becomes a part of a cluster and is visible on the Web UI.
• Record and replay SSH sessions for knowledge sharing and auditing purposes.
• Collaboratively troubleshoot issues through session sharing.
• Connect to clusters located behind firewalls without direct Internet access via SSH bastions.
• Ability to integrate SSH credentials with your organization identities via OAuth (Google Apps, Github).

Teleport is built on top of the high-quality Golang SSH implementation and it is fully compatible with OpenSSH."
