History & context
The Linagora admin team was looking for an Open Source tool to streamline the hassle of managing SSH public keys across a large datacenter. Thus sshGate was born, as a script to publish and revoke public keys on all targets. Later on came the need to be able to define a finer grain policy. Going beyond, sshGate has become an ssh “gateway”, centralizing access and controls, and allowing new features such as logging TTYs.
An open source project called “ssh proxy” exists on freshmeat, but has not been updated since 2008. It has fewer functionalities than sshGate, and requires a specific client. A closed source product called “Observe-it” provides multiple features, including support for Citrix, and rdp. The number of target is limited, as in a paying feature. A void in the Open Source arena was begging to be filled !

One year later …
sshGate has been deployed at Linagora since September 2010 to assist the admins in their tasks ; it is now able to record and replay TTYs as an added diagnostic feature. It now supports the full range of OpenSSH options, including LocalForward, RemoteForward, and ProxyCommand.
