Rport helps you to manage your remote servers without the hassle of VPNs, chained SSH connections, jump-hosts, or the use of commercial tools like TeamViewer and its clones.

Rport acts as server and client establishing permanent or on-demand secure tunnels to devices inside protected intranets behind a firewall.

All operating systems provide secure and well-established mechanisms for remote management, being SSH and Remote Desktop the most widely used. Rport makes them accessible easily and securely.

ATTENTION:
Only version < 1.0.0 is open source!
The latest open-source version is 0.9.12.
Clients >= 1.0 will not connect to an open-source server <= 0.9.12.

"The RPort open-source version has been discontinued 2023-09-20! All packages for RPort >= 1.0.0 require a valid license subject to a paid subscription.

Do not upgrade the rport client to >= 1.0.0 if you are still running the oss server < 1.0.0. Clients will refuse to connect, if the server is not licensed."
