Important

Current version of this code has moved into a proper GitHub repository: https://github.com/palant/opensmtpd-filters

The OpenSMTPD documentation currently suggests using either opensmtpd-filter-dkimsign or opensmtpd-filter-rspamd for DKIM support. The former lacks functionality and requires you to compile code from some Austrian web server yourself. The latter is overdimensioned for my needs. So I’ve written my own fairly simple filters in Python.

Prerequisites

These filters require Python 3 with dkimpy module installed. You can optionally install pyspf module as well, if you want dkimverify.py to perform SPF verification as well.

Linux workstation security checklist

This is a set of recommendations used by the Linux Foundation for their systems administrators. All of LF employees are remote workers and we use this set of guidelines to ensure that a sysadmin's system passes core security requirements in order to reduce the risk of it becoming an attack vector against the rest of our infrastructure.

Even if your systems administrators are not remote workers, chances are that they perform a lot of their work either from a portable laptop in a work

Installing Docker CE on Ubuntu 17.10 Artful Aardvark

As of 20/10/2017, a release file for Ubuntu 17.10 Artful Aardvark is not available on Download Docker.

If you are used to installing Docker to your development machine with get-docker script, that won't work either. So the solution is to install Docker CE from the zesty package.

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
