gereal - how to painlessly access serial consoles

Serial consoles are still a big thing to access servers, network devices, embedded devices, Raspberry Pis and many other computers. There is a myriad of methods available to access those serial consoles from Linux.

gereal is a new method to access serial consoles using screen in a comfortable way. The main extraordinary feature is that the session automatically opens during system boot and that users can attach to a running session. Attaching to a running session allows one to see what the device has printed on its serial console before the session was attached to, and one can even scroll back in the console history.

gereal makes use of systemd generators. Time permitting, I’m going to give an introduction to using systemd generators as well.

Suggestions for OpenPGP Key Management in Debian

In this talk, I will outline how I am managing my OpenPGP key, that I also use to sign my Debian packages. The talk will outline the basics about how to work with subkeys, how to keep your Master key properly offline, safe and disconnected while still being able to work with subkeys. PGP Smartcards, Yubikeys etc will also be covered. This talk will give you the information you need to improve your key security, while leaving you to take informed decisions which ideas are yours to take and where the overengineering begins.

Intended audience is people who already have basic knowledge about PGP. I won’t be giving the usual “Alice wants to talk to Bob without Mallory being able to eavesdrop” introduction to public key cryptography.
