Roadmaster / sshtron

Play Tron over SSH

SSHTron is a multiplayer lightcycle game that runs through SSH. Just run the command below and you'll be playing in seconds:

$ ssh sshtron.zachlatta.com

Controls: WASD or vim keybindings to move (do not use your arrow keys). Escape or Ctrl+C to exit.

Code quality disclaimer: SSHTron was built in ~20 hours at BrickHack 2. Here be dragons.

Running Your Own Copy

Clone the project and cd into its directory. These instructions assume that you have your GOPATH setup correctly.

# Create an RSA public/private keypair in the current directory for the server
# to use. Don't give it a passphrase.
$ ssh-keygen -t rsa -f id_rsa

# Download dependencies and compile the project
$ go get && go build

# Run it! You can set PORT to customize the HTTP port it serves on and SSH_PORT
# to customize the SSH port it serves on.
$ ./sshtron

CVE-2016-0777

CVE-2016-0777 revealed two SSH client vulnerabilities that can be exploited by a malicious SSH server. While SSHTron does not exploit these vulnerabilities, you should still patch your client before you play. SSHTron is open source, but the server could always be running a modified version of SSHTron that does exploit the vulnerabilities described in CVE-2016-0777.

If you haven't yet patched your SSH client, you can follow these instructions to do so now.
