Pterodactyl SSH Tunnels

A simple server to spawn SSH tunnels when servers are starting, and close them when servers are stopping on a pterodactyl node.

Support for UDP will be added in the future, however currently it only supports TCP through SSH tunnels.

Building

mvn clean compile assembly:single

HOW TO INSTALL (Using crontab and screen)

1. Clone the repository
2. Install java 11 and maven (apt install openjdk-11-jre-headless mvn)
3. Build the server (cd pssht && mvn clean compile assembly:single)
4. Open crontab crontab -e
5. Insert @reboot screen -S pssht_server -dm bash -c "cd ~/PSSHT_LOCATION/target/ && java -jar pterodactylAPI-ssh-tunnels-1.0-SNAPSHOT-jar-with-dependencies.jar"
6. Reboot

A screen called pssht_server with pssht running inside of it should now be running.

HOW TO USE

This server should be installed on a server which has access to the pterodactyl node(s). An obvious place would be the node itself.

Once you run the server once, it creates a config.properties file. Edit this to your suite needs. Make sure to copy SSH keys for the user tunnel-user on the server tunnel-remote.
This can be done with 2 easy steps:

1. ssh-keygen -t rsa (if no ssh keys exist on the server yet)
2. ssh-copy-id tunnel-user@tunnel-remote (copy the ssh key)

Now run the server, and it should work automagically.
