Custom SSH server written in Go. Instead of a shell, you get a chat prompt.

Join the party:

$ ssh ssh.chat

Please abide by our project's Code of Conduct while participating in chat.

The host's public key is ssh.chat ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIKPrQofxXqoz2y9A7NFkkENt6iW8/mvpfes3RY/41Oyt and the fingerprint is SHA256:yoqMXkCysMTBsvhu2yRoMUl EmZKlvkN ZKmL3115xU (as of 2021-10-13).

If you see something different, you might be MITM'd.

(Apologies if the server is down, try again shortly.)

Recent releases include builds for MacOS (darwin/amd64) and Linux (386, amd64, and ARM6 for your RaspberryPi).

Grab the latest binary release here.

Play around with it. Additional deploy examples are here.

Most people just want the latest binary release. If you're sure you want to compile it from source, read on:

You can compile ssh-chat by using make build. The resulting binary is portable and can be run on any system with a similar OS and CPU arch. Go 1.8 or higher is required to compile.

If you're developing on this repo, there is a handy Makefile that should set things up with make run.

Additionally, make debug runs the server with an http pprof server. This allows you to open http://localhost:6060/debug/pprof/ and view profiling data. See net/http/pprof for more information about pprof.

After doing go get github.com/shazow/ssh-chat/... on this repo, you should be able to run a command like:

$ ssh-chat --verbose --bind ":22" --identity ~/.ssh/id_dsa

To bind on port 22, you'll need to make sure it's free (move any other ssh daemons to another port) and run ssh-chat as root (or with sudo).
