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.

Download the latest binary release, unpack the .tar.gz and run sudo make install. This will copy Teleport binaries into /usr/local/bin and the web assets to /usr/local/share/teleport.

Then you can run Teleport as a single-node cluster:

teleport start 

You need to have Golang v1.7 or newer.

Clone this repository into $GOPATH/gravitational/teleport and run make.

You'll have to create /var/lib/teleport directory and then you can start Teleport as a single-node cluster in development mode: build/teleport start -d

If you want to release your own Teleport version, edit this Makefile, update VERSION and SUFFIX constants, then run make setver to update version.go

If you want to cut another binary release tarball, run make release.

NOTE: The Go compiler is somewhat sensitive to amount of memory: you will need at least 1GB of virtual memory to compile Teleport. 512MB instance without swap will not work.

Mature tech companies with significant infrastructure footprints tend to implement most of these patterns internally. Teleport allows smaller companies without significant in-house SSH expertise to easily adopt them, as well. Teleport comes with an accessible Web UI and a very permissive Apache 2.0 license to facilitate adoption and use.

Being a complete standalone tool, Teleport can be used as a software library enabling trust management in complex multi-cluster, multi-region scenarios across many teams within multiple organizations.

Teleport has completed a security audit from a nationally recognized technology security company. So we are comfortable with the use of Teleport from a security perspective.

However, Teleport is still a relatively young product so you may experience usability issues. We are actively supporting Teleport and addressing any issues that are submitted to this repo. Ask questions, send pull requests, report issues and don't be shy! :)

• Teleport does not officially support IPv6 yet.

Teleport was created by Gravitational Inc. We have built Teleport by borrowing from our previous experiences at Rackspace. It has been extracted from Gravity, our system for helping our clients to deploy and remotely manage their SaaS applications on many cloud regions or even on-premise.
