Simple automated backup system for Linux

I hate re-doing things. One of my biggest fears is that the masterpiece of code I just churned out will be lost tomorrow and I'll have to do it again. It's perfect the way it is! I could never achieve that the same way again! Ok, that was a bit dramatic, but seriously, data has some meaning to all of us, so if it's worth having, it's worth being protected from accidental loss. In this post, I'm going to describe a simple system for backing up just the data you care about on your Linux syste...

Setting up a home network DHCP/DNS server with dnsmasq

When you have too many networked devices like I.., uh, someone I know does, it becomes very difficult to keep up with IP addresses. The problem is two fold. First, to be able to get to every device, you have to give them all static IPs. Otherwise your DHCP server (typically your cable/DSL router) will give them seemingly random IPs if they restart. Assigning static IPs can be a real pain, especially with embedded devices that have clunky, or sometimes no interface for setting up IPs. If that...

If you access remote machines through SSH a lot, it gets to be a real pain to type in your password over and over. Fortunately, we can easily eliminate the need to keep typing those passwords and increase the security of SSH login process at the same time!

SSH keys

The key (see what I did there?) to eliminating the need to constantly re-type your password is using SSH keys to log in. When you generate an SSH key, you are creating a public/private key pair. The private side, you need ...

Setting up a headless Raspbian server with a static IP

Several of my articles here on carpie.net make use of a Raspberry Pi as a headless server. Instead of explaining it in each article, being a proper programmer and all :), I've factored those instructions out into an article of their own.

Making a "headless" Pi just means that, once we've got a Pi setup, it can sit in a dusty, dreary corner of our home or office dutifully doing its job with nothing connected to it but power and maybe a network cable. Since we are setting up a headless server...
