Recently, I needed to redo my email server. The mail reasons for this were that I was finding it hard to control spam, and I could not send email. As I was looking around for a guide, or for examples I found the Citadel software. Citadel is a one stop solution, so rather than installing multiple pieces of software for different aspects of a mail server I install, and secure one. Citadel has a long heritage coming out of the BBs scene of the 1980s and 1990s.

A while ago, I wrote about some fun things to do to help secure your servers. Among the things I included was information about SSH banners, and Message of the Day files. At the time, I was not able to generate dynamic content for the Message of the day. Recently, I learned how to accomplish dynamic content on CentOS/Redhat based Linux systems. My goals for this project was to show the following:

• System Information
• User Information
• Weather and Fortune
• System Name
• Warnings and Rules

Over the last few weeks I’ve been working on a Perl English to Pig Latin script. For testing I used the text of The Time Machine by: H.G. Wells from Project Guttenberg. You can get the full code, and the text I used for testing at my GitHub Repo.

I was challenged to write Hangman. It started out with a simple enough idea. Have the computer pick a word from a wordlist, and present the hangman structure, and proceed through the game. As is often the case, while the idea is simple, it took me a bit to figure it out. See my Github Repo for the full code

Recently I upgraded from Jekyll 2.x to 3. When I did the upgrade the plugin I was using to create category pages started reporting depreciation errors. I started looking into creating the category pages a different way, and If I could create them without a plugin, I decided that would be the best way to do it.

I wanted to add a related post feature to my post pages, to help content be found more easily. I decided to make use of my tags, to help group posts together.

In this article I will share how I accomplished this, and where I found the code I used.
