LAN Chat Servers

Recently I wanted a LAN Chat Server for my CTF Network.  A few weeks ago I had used chatplus on Ubuntu, and I thought it was so easy to install and use.  For the server, all you do is sudo apt-get install chatplus_server, and start it up.  Then all the clients just need to sudo apt-get install chatplus_client, and they can connect easily to the server.  

However, my Admin box on the CTF Network is a Winblows box, so I needed a Windoze program.   I did some playing around, and it looked like the simplest solution to my needs was Openfire.  http://www.igniterealtime.org/projects/openfire/

I downloaded and installed the Openfire executable, and it installed pretty easily.  I looked around, and although it said that users could create their own accounts, it sure looked to me like I had to create the accounts myself.  Here's a screenshot of the 10 users (user1-user10) I created, each with a password of "password."


By default, there's a group room called "conference" room.  So I joined it with a Pidgin client in Windoohs, and a Pidgin client in Backtrack.   Here's a screenshot of that room:


I installed pidgin in my box to see what its client would look like.  Here's that:

Since most of the players on the CTF network will be using Backtrack, I thought I'd install that and try it as well.   Here's the configuration screens to Pidgin in Backtrack:


Even though it appeared users couldn't just log in like they could when I used chatplus (meaning, it appears that I have to create an account for them before they can log in), it still seemed like a pretty neat chat program.  I'll probably leave it on the CTF for a while and see if anyone uses it.  If not, I'll probably just delete it.

ADS-B plotting with Kali (and other SDR goodies)

Recently I wanted to try some Software Defined Radio stuff.   
I had a RTL-SDR, FM+DAB, DVB-T USB Stick Set with RTL2832U & R820T. that I got from: http://www.amazon.com/gp/product/B00C37AZXK/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1
But, even though this dongle would break out FM radio stations, and ATC frequencies (like the local Ground Control, tower, and even ATIS), which was cool, it wouldn't break out ADS-B.   
Thus, I bought a Vantech Green Mini RTL2832U R820T DVB-T SDR DAB FM USB DIGITAL TV Tuner Receiver RTL-SDR Project + DAB dongle Tuner MCX Input from Amazon, and tried this.  
This dongle was able to listen to the 1090MHz frequency required for ADS-B (as it goes from 25MHz to 1700MHz).  There were tons of Windows programs out there for breaking out and plotting ADS-B Mode S broadcasts, but not many for Linux.  
For Kali Linux, here's how I got it running and plotting planes around my home:

Beaglebone Black as a Wireless Intrusion Detection System (WIDS)

Recently I have been wanting a wireless IDS (WIDS) to detect nefarious wifi activity.  I also had a Beaglebone Black hanging around that I wanted to put to good use.   This seemed like a perfect match, and indeed it seems to be so!

I did some research on WIDSs, and although there is SUPPOSED to be several out there, nearly all that I seemed to find was commercial and Windows-based products, not something I could use myself.   
About the only exception to that rule was Kismet, so I decided to give that a try.  Kismet is supposed to work as a WIDS, and per its documentation should catch the following attacks:
Kismet supports the following alerts, where applicable the WVE (Wireless Vulnerability and Exploits, www.wve.org) ID is included: AIRJACKSSID Fingerprint Deprecated The original 802.11 hacking tools, Airjack, set the initial SSID to 'airjack' when starting up. This alert is no longer relevant as the Airjac…

Temper Temperature monitor on a Beaglebone Black

Beaglebone Black as a temperature monitor:

Recently I wanted to monitor the temperature of my shed.  I thought I'd use a small computer such as a Raspberry Pi or a Beaglebone or Odroid.

My Raspberry Pi boxes were all in use, so I grabbed my Beaglebone, which was doing nothing.

I flashed it with the Debian9.32018-03-054GB SDIoTimage, but that seemed like it was running lots of bloatware and the ethernet interface wouldn't take a static IP with /etc/network/interfaces.

So I went with the Debian9.32018-01-284GB SDLXQTi image instead.  I still had the same problem, that lots of junk was running, and I couldn't configure my interface by modifying /etc/network/interfaces

So my first step was to get rid of all the bloatware.  If you're using a Raspberry Pi or something, you can skip this and just go to the second step below

STEP 1--Remove Blotatware from Beaglebone Black:
