Racket SSH server (and client)

This is a Racket implementation of the SSH v2 protocol. It's written to work with Marketplace, but could readily be adapted to work with other I/O substrates. (It originally used Racket's sync and events directly.)

The code is not quite fully separated into a reusable library yet: at present, it is a hard-coded Racket REPL server. Changing this is straightforward, but low-priority right now. Patches welcome!

How to compile and run the code

You will need the latest prerelease version of Racket. Any version newer than or equal to Racket should work. Nightly-build installers for Racket can be downloaded here.

Once you have Racket installed,

raco pkg install marketplace bitsyntax

to install Marketplace (note: will take a long time) and bitsyntax, and then


(or the equivalent, raco make new-server.rkt) to compile the SSH code. Once it has compiled successfully,

racket new-server.rkt

will start the server running on localhost port 2322. Log in to the server with

ssh localhost -p 2322

To enable debug output, try

MATRIX_LOG=info racket new-server.rkt
