Intro This is far from exhaustive, but I needed to perform some light benchmarks in CRC, MD5 and SHA hashing. The idea was to compare crc, md5 and sha as well as compare Naive Python hashing to Linux based tools.

When running the Gnome Desktop Environment on Debian there is a secrets tool that automatically runs called Gnome Keyring. This tool provides multiple functions: ssh keys - ssh keys in ~/.

Recently I wanted to see if I could make my public cloud-based Linux infra more secure via LUKS (Linux Unified Key Setup) disk encryption. I realise that one must fully trust one’s cloud provider, as they have access to the hardware.

Modern Linux can have complicated DNS setup. However this is now necessary, gone are the days when you could just set one static name server in /etc/resolv.conf and walk away. This little piece just documents how I’ve got my systems setup.

Recently I helped troubleshoot a networking issue with a 1Gbps link that was being fully saturated. In the end we configured a mirror port and dumped the traffic to analyse it.
