ssh-chat
Custom SSH server written in Go. Instead of a shell, you get a chat prompt.
Demo
Join the party:
$ ssh ssh.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.)
Downloading a release
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.
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).
