Wifi in a field

This post is part of [tj]’s blog more in June challenge. You should join us and take part - just make 4 posts in June! As part of the general move to do more radio / do radio in a field, I’m configuring a raspberry pi to be a permanent companion to my radio.

Yubikey GnuPG + SSH Agent with Fish

So I’ve had a lot of GPG issues over the last few months, and part of that has been me not bothering particularly to ensure I’ve got a consistent setup across my machines. Part of the issue is that I’m using a yubikey, and keep having to look at external references to make sure it works consistently.
