Custom SSH server written in Go. Instead of a shell, you get a chat prompt.
Join the party:
$ ssh chat.shazow.net
The server's RSA key fingerprint is e5:d5:d1:75:90:38:42:f6:c7:03:d7:d0:56:7d:6a:db. If you see something different, you might be MITM'd.
(Apologies if the server is down, try again shortly.)
Usage:
ssh-chat [OPTIONS]
Application Options:
-v, --verbose Show verbose logging.
-i, --identity= Private key to identify server with. (~/.ssh/id_rsa)
--bind= Host and port to listen on. (0.0.0.0:22)
--admin= Fingerprint of pubkey to mark as admin.
--whitelist= Optional file of pubkey fingerprints that are allowed to connect
--motd= Message of the Day file (optional)
--pprof= enable http server for pprof
Help Options:
-h, --help Show this help message
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 ":2022" --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).
You can run ssh-chat using a Docker image without manually installing go-lang:
$ docker pull alvin/ssh-chat
$ docker run -d -p 0.0.0.0:(your host machine port):2022 --name ssh-chat alvin/ssh-chat
See notes in the header of our Dockerfile for details on building your own image.
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.
