In this post, I will go over installing Rocket.Chat on a server running CentOS 7 with SELinux ENABLED as well as exposing the service through an Apache Reverse Proxy with SSL enabled. So far, I really like Rocket.Chat. The feature set is awesome and it's a joy to

As always, use documents you find on blogs at your own risk. This worked for me. It may not work for you. I've recently started playing with an install of Nethserver and I believe I've found the replacement for my Zentyal server. Zentyal was great when I first discovered it,

If you work with Linux in an enterprise setting, you probably have come into contact with the lovely Qualys security scanner. One GREAT side effect of this scan, is that your root user's BASH history file gets overrun. So much so that you essentially no longer have a history file

[](http://ampache.org/) Been getting bored and spinning up VMs like a fiend here of late. The latest one is an Ampache Server. This one had proven to be more of a chore than I'd originally hoped. CentOS 7 may not have been

[](http://piwik.org/) Got bored today and decided to spin up a Piwik server. This is a rundown of the steps I took to install Piwik on a CentOS 7 server with SeLinux enabled. Initial Steps From Piwik Website To run Piwik your

I've recently discovered that the great people at GitLab have released the GitLab-Omnibus. This project creates full-stack platform-specific downloadable packages for GitLab. This is great, especially since a manual install on a Red Hat system can be a bit of a pain to maintain. Use this doc at your own

So, you have some existing piece of software that really REALLY...I MEAN REALLY wants its input on the command prompt. That is to say command < /file/with/input fails ya, and this particular piece of software does not have a flag to include a setting you want (in this

Getting Pithos up and running on Arch was relatively painless. I was able to build it from source with minimal dependency pain, but I've since ditched that method for using the AUR. The 'Manual' AUR Method I'd recomend this method if you are just starting out. It's good to learn

I like retro terminals. There, I said it. If it makes me some form of Techno-Hipster, then I shall accept my fate. When feeling uber-nerdy, I would load up phosphor from xcreensaver and run a terminal session it it. /usr/lib/xscreensaver/phosphor -program bash -scale 2 -delay 1000 Then,

####UPDATE "Pithos has official RPMs available in both RPMFusion and Copr now, so please use those to install! If there are ever any gstreamer issues using RPMs, please report it as a bug Thanks!" Source Comment I've got back on the Fedora train (at least on my home desktop) and

I just spent the better part of a day trying to migrate to nginx and accomplish global error pages across all my hosted sites. This sounded easy enough, and hey, I did it on apache before. Couldn't be too hard... Famous last words. SO...rather than dull you with the

-UPDATE- I've given up on Fedora19 for now. It decided to stop working with the ever-so-informative error of 'Something Went Wrong.' I ended up removing ALL gnome3 items installed, but that still only allowed for a few minutes of work before it would freak out on me. Sadly, I

So, I've written a few Bash scripts in my day. I'm by no means a Bash expert, but I get by. In a few of my scripts, I try to add argument flags to add usability, but nothing really fancy. Just one flag here and there. I'm nowhere near the

The BIGGEST headache thus far about working in a Windows-centric environment has been trying to handle our work email elegantly. That is, not having to open a VM to use Outlook or open a second browser (Firefox) to have a decent OWA client. I tried Evolution (Gnome3's default mail client)

I've been banging my head against this one since I started using a second workstation here at work (Fedora 17). File sharing, mouse and keyboard sharing, and syncing my wallpapers over the network was pretty simple, but there was one nagging issue. Sound. I found myself missing chats due to

So, I started a simple script that randomly selects a wallpaper from a directory and sets it as the background on my Fedora 17 laptop. That part was simple enough, and it turned out that a coworker had already written such a script in perl. #!/usr/bin/perl -w use

**UPDATE** HOLY LORD!! I used to write my if-then statements *UGLY*. Fixed that for my sanity. Ok, as the title suggests, this is about file state testing. I was recently writing a script that relied on the contents of a dynamically created file. If the file EXISTS and HAS contents

Recently, I stumbled upon a thread on Reddit about the i3 Tiled window Manager. To say the least, I was intrigued. I've been looking for ways to increase productivity on my Linux desktop for a bit now. Usually that just meant customizing Gnome Shell to display system information (CPU, Net,

Pianobar is a command line Pandora radio client. Disclaimer: Due to the nature of this software, one might suggest getting the paid version of Pandora to make yourself feel better when using this. (pianobar has infinite skips and no ads...) Fedora 16 or 17 Repos yum localinstall --nogpgcheck http://download1.

-UPDATE- Openmeetings version 2.0 is out, and was a lot easier to get up and running via the supplied Binaries. (You could still download the source and use the rest of this article as a guide) Get the Binaries Here Openmeetings provides video conferencing, instant messaging, white board, collaborative

-UPDATE- Wrote up a quick Fedora 20 howto here -UPDATE- The latest version at the time of writing (currently 0.3.17) also seems to require pylast to be installed. I came to this conclusion after attempting to update to 0.3.17 from source, and everything borked. After some
