If you are using RustDesk you should have your own RustDesk Server, these docs will help you on your RustDesk journey.
Support is available via our Discord for OSS and email for Pro.
How does self-hosted server work?
There are technically two executables (servers):
hbbs- RustDesk ID (rendezvous / signaling) server, listen on TCP (21114- for http in Pro only,21115,21116,21118for web socket) and UDP (21116)hbbr- RustDesk relay server, listen on TCP (21117,21119for web socket)
When you install via installation script / docker compose / deb, the two services will be both installed.
Here is illustrations of how RustDesk client communicates with hbbr / hbbs.
As long as RustDesk is running on a machine, the machine constantly pings the ID server (hbbs) to make its current IP address and port known.
When you start a connection from computer A to computer B, computer A contacts the ID server and requests to communicate with computer B.
The ID server then attempts to connect A and B directly to each other using hole punching.
If hole punching fails, A will communicate with B via the relay server (hbbr).
In the majority of cases, hole punching is successful, and the relay server is never used.
Here is a discussion about Should you self-host a rustdesk server?
Basic Setup
Set up your own server instance manually.
Ports Required
Ports required for RustDesk Server self-hosting depends largely on your environment and what you want to do with RustDesk. The Examples shown throughout the docs will generally have all ports suggested to be opened.
Core Ports:
TCP 21114-21119
UDP 21116
The above 21115-21117 are the minimum required ports for RustDesk to work, these handle the signal and relay ports as well as NAT traversal.
Additionally TCP ports 21118 and 21119 can be opened if you want to use the RustDesk Web Client.
For Pro users without an SSL Proxy you will need to open TCP port 21114 for the API to work alternatively using an SSL Proxy open TCP port 443.
Test Ports are opened
To check ports are opened and working you can use test-netconnection domain.com -p 21115 with PowerShell or CanYouSeeMe.org.
