How to setup fwknop

Cloud Setup

Using sshd_conf from my other place configure a bastion to run on 2 ports
- use the other random port to help you set all this up!
expose them on GCP
also expose udp/62201 for the knock (62201 is the default, but you can change in the config)
on a debian instance install fwknop-server
configure ip tables as follows:

Embedding an SSH-accessible REPL in a Clojure process

N.B. This is now a library, thanks to the efforts of the wonderful @mtnygard. And the README does a good job of making clear just how terrible an idea it is to actually do this. :)

As any Clojurist knows, the REPL is an incredibly handy development tool. It can also be useful as a tool for debugging running programs. Of course, this raises the question of how to limit access to the REPL to authorized parties. With the Apache SSHD library, you can embed an SSH server in any JVM process. It takes only a little code to hook this up to a REPL, and to limit access either by public key or

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
