ssh-chat

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

Demo

Join the party:

$ ssh ssh.chat

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

The server's RSA key fingerprint is

MD5:e5:d5:d1:75:90:38:42:f6:c7:03:d7:d0:56:7d:6a:db
or
SHA256:HQDLlZsXL3t0lV5CHM0OXeZ5O6PcfHuzkS8cRbbTLBI
. If you see something different, you might be MITM'd.

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

Compiling / Developing

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
.

Quick Start

Usage:
  ssh-chat [OPTIONS]

Application Options: -v, --verbose Show verbose logging. --version Print version and exit. -i, --identity= Private key to identify server with. (default: ~/.ssh/id_rsa) --bind= Host and port to listen on. (default: 0.0.0.0:2022) --admin= File of public keys who are admins. --whitelist= Optional file of public keys who are allowed to connect. --motd= Optional Message of the Day file. --log= Write chat log to this file. --pprof= Enable pprof http server for profiling.

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 ":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).
