I took a few weeks off from doing anything productive. I went on a trip over the holidays, but now I am back.
I worked a bit on nftables. I went to the Austin Linux Meetup last week, and one of the attendees and I had a chat about firewalls. He was not too keen on things like ufw as a front to iptables, and felt it was just better to learn iptables. I think that the plan is for nftables to replace iptables.
I also worked a bit on some commands to do random passphrase generation on the command line. I will post about that soon.
