Preface This is not going to be a very technical blog. If you are looking for normal Linux systems reading, this isn’t it. What I want to cover is why I moved off of a hosted blog platform. So I’v...

Actions were done as root. Prompts are $ instead of # to differenciate between comments in the output. I showed systemctl cat output instead of on disk file content to show runtime state of...

We’re discussing Linux firewalls. As such this post is technical. While I’m trying to show how to write a modular firewall system vs go into detail about networking, it does help to have some backg...

There are lots of articles and books that cover Git and I’m not one to reinvent the wheel - I always try to bring something new to the table. First, lets look at what’s out there so we have a good ...

I figured I needed to get back on IRC today, went to login and got this message: 08:58 [Freenode] -NickServ(NickServ@services.)- This nickname is registered. Please choose a different nickname, or...
