Email servers? Let’s do it.

Background: Anyone who gets anywhere near INFOSEC information tends to get a little paranoid….or a lot of paranoid. This is just a side effect of knowing what you can do to own people’s information and learn about them. Email can be a weakness in this.

I encourage everyone to think about worst case scenarios related to this. What happens if your primary email account is compromised? What happens if you use it for everything? Well, then someone now can reset any account you have without Two-Factor authentication and even some with it.

Fast forward, and now we have an issue: Do you set up a throw away email for every account you have? Do you use something like ProtonMail that boasts double encryption? What if you set up your own system? Hm…..

In walks iRedMail. Opensource, beautifully simple and it just works. I don’t send many emails (maybe a couple a month at tops) and mostly use it for either news/updates, or for account information. This is good, because setting up your own email solution can get blacklisted quickly and not be able to send emails out. This is fine for me, so using a new set up works like a charm and runs off an encrypted system internally. Add to this that the website isn’t accessible via web, and we have a more solid and secure system. It’s nice getting my feet wet in these projects should other opportunities arise for freelance work as well.

Sometimes peace of mind is worth the extra effort.

Overly complicated ideas: IRC command of servers!

A little background: I get these ideas once in a while that eventually come to fruition after a couple months of brainstorming and tinkering. I’ve had the idea for a while of having a central way to maintain my fleet of Linux servers I host along with Windows if possible. In the past, I used ssh keys to login and run updates. It worked pretty well but I’d like a way to remotely run and/or monitor these. Enter IRC…

Most complicated home network ever…ever.

A little background:

I’ve been building and tinkering with computers since I was about 12, when I got my own laptop and desktop both from garage sales and began swapping parts, doing OS upgrades from floppy disks and doing whatever I could to tinker with them. Fast forward almost two decades, and I’m still at but on a much larger scale.

Arduino Wireless Logging, Post Three: Mysql, PHP, and a little networking

Here’s where things started to get a little more complex. At this point, I have a wireless system to transmit data from multiple nodes to a central hub (node0) which collects and shows the data via serial connection.

The general idea/goal is this:

  • Arduino Nodes send data to central node
  • Central node is connected to home network and sends this data to a┬áLAMP server (Linux-Apache-Mysql-PHP)
  • The server takes this data, breaks it into a mysql statement, and pushes it into the database to log
