Configure Relay Servers

RustDesk Pro - Install Additional Relay Servers with Geo Location using docker

The simple install creates a relay server (the hbbr process) implicitly on the same machine, you do not need to specify relay server explicitly.

If you wanna create additional relay server explicitly on another machine, please run hbbr by following OSS installation. You can find hbbr in rustdesk-server-linux-amd64.tar.gz, rustdesk-server-hbbr_<version>-<arch>.deb, rustdesk-server-windows-x86_64.tar.gz or in docker (sudo docker run ... rustdesk/rustdesk-server-pro hbbr).

hbbr does not require a license and is the same as the open source version.

You can have several relay servers running across the globe and leverage GeoLocation automatically to use the closest relay server, giving you a faster experience when connecting to remote computers. hbbs automatically checks if these relay servers are online every several seconds, it only choose online relay servers.

You will need the private key pair id_ed25519 and

1 - If docker is already installed, connect to your server via SSH and create a volume for hbbr.

# docker volume create hbbr

The volume hbbr should be located in /var/lib/docker/volumes/hbbr/_data.

2 - Copy the private key pair to the volume location, in this case we will use SCP to copy the files.

The command syntax is scp <path/filename> username@server:</destination/path>.

# scp id_ed25519 root@
# scp root@

3 - Deploy the hbbr container using the volume previously created. This volume has the private key pair needed to run your private relay server.

# sudo docker run --name hbbr -v hbbr:/root -td --net=host rustdesk/rustdesk-server hbbr -k _

4 - Check the running logs to verify that hbbr is running using your key pair.

# docker logs hbbr

INFO [src/] **Private key comes from id_ed25519**
INFO [src/] #blacklist(blacklist.txt): 0
INFO [src/] #blocklist(blocklist.txt): 0
INFO [src/] Listening on tcp :21117

Depending on your OS, you might want to block/allow IPs using a firewall.

In our case, running Ubuntu we want to allow any TCP connections, to ports 21117 and 21119.

# sudo ufw allow proto tcp from any to any port 21117,21119

Enable the firewall

# sudo ufw enable

Check the status

# ufw status

Configure RustDesk Pro for Geo Location using Web Console

Register and Download the GeoLite2 City database file

To use geo location, hbbs needs access to the MaxMind GeoLite2 City database. The database is free and you can register to download the file and get an API key.

Start by creating an account (if you don’t have one) by going to the website. Go to Download Databases and download GeoLite2 City, choose the gzip file and you should have the mmdb file when decompressing it.


If you installed RustDesk Pro using the installation script on a Linux machine, the mmdb file needs to be moved to /var/lib/rustdesk-server/.

For Docker installations the file should be in the volume you mapped when deploying the container mapped to /root.

Get an API key to automate the process - Linux servers

You need to update this file regularly and we can use a cronjob to do that. You will need an API key to access the download link which is free.

Go to Manage License Keys and generate a new license key.

You can automate the download process in a few ways, but you add the following command to your crontab replacing {Your Access Key} with the API key you got from the previous step.

/usr/bin/curl -L --silent '{Your Access Key}&suffix=tar.gz' | /bin/tar -C '/var/lib/rustdesk-server/' -xvz --keep-newer-files --strip-components=1 --wildcards '*GeoLite2-City.mmdb'

Change settings in RustDesk Pro Web Console

Add your relay server IP addresses or DNS names (DNS is supported as of version 1.1.11) to the Relay Servers. Port is not required, 21117 port is used explicitly.

Add a Geo Override but adding the server IP address and the coordinates where the server is located.

Click Reload Geo and your list should look similar to this.

To confirm the results, check your hbbs logs when clicking Reload Geo, you should see a message showing the relay server IP addresses and their coordinates.

If you are running RustDesk Pro on a Linux machine use the command RUST_LOG=debug ./hbbs to view the logs. If you are running on a Docker container user docker logs hbbs.

RUST_LOG=debug ./hbbs

INFO [src/] GEOIP_FILE: ./GeoLite2-City.mmdb

You can also confirm the relay requests directly on your hbbr instances, simply by checking the container logs.

# docker logs hbbr
