Labrea Tarpit on Raspberry Pi

I have been playing with my Raspberry Pi, turning it into a Pwn Plug and such, and started trying to think of a good home-defense use for it.

Enter Labrea (http://linux.die.net/man/1/arp-scan)

Labrea responds to ping scans, port scans, and such, and even throttles the traffic to slow down potential hackers/malware. It also stores its results in the /var/log/syslog, acting like a mini IDS! But who wants to use a full-blown machine to do something so simple? This sort of activity is PERFECT for the Raspberry Pi. Low power, low noise, and inconspicuous.

With a simple apt-get install labrea, I was up and running. True, I had done a bunch of tweaking prior to that, so if that single command doesn't work for you, then I'm sorry I didn't document all my efforts.

Running Labrea was as simple as: #labrea -v -i eth0 -sz -d -n network/CIDR

I ran a ping scan of my network, and Labrea dutifully responded everywhere. I ran a NMap scan of a host, and it had thousands of ports open (on a host that wasn't even there). It is truly a fun way to mess with your network, and with a Pi you can mess very cheaply!

HP c6180 Printer and Vista

Hp c6180 driver issues with Vista Home Premium My wife has a Vista Home Premium laptop, and the HP C6180 Photosmart printer keeps disappearing from her available printers. The only way I've found to fix the problem is to reinstall all the HP software. When I do this, I have to download the (large..507M software from HP, or reinstall the printer (ONLY the printer, not the scanner) with the installation disk, as the drivers are not discovered with a "Windows Update" setting. My guess is that is because HP doesn't like people to install only the printer driver, which would be easy, but they want folks to install all their crapware as well, so they are withholding the drivers from the on-line Microsoft printer database. So keep your installation CD! I've also found that unless I install everything on the CD or in the Full Version download (HP Customer Participation Program, HP Imaging Device functions, HP OCR SW, HP All-In-one SW, HP Photosmart Essential, HP

atftpd vs tftpd-hpa

Recently I was trying to tftp files from a Windows computer to a Kali box. One version of Windows worked, but another didn't. After much troubleshooting, here were my symptoms: I could tftp a file from-to any Kali box from-to another Kali box I could NOT tftp files to a specific Windows 7 box from any Kali box I could NOT tftp files to a Chrooted-Ubuntu-Chromebook box from a Kali box After MUCH troubleshooting, going through every setting in atftpd, it seemed like it literally was a client OS problem. Different clients simply would not download files---unacceptable. Thus, I switched to tftpd-hpa. To install: apt-get install tftpd-hpa files go to/come from /srv/tftp, but it needs to be a tftp user. Thus, I needed to: chroot -R /srv/tftp Also, if you want to be able to put files ON the tftp server (from a client), you need to modify /etc/default/tftpd-hpa: change "TFTP_OPTIONS="--secure" to "TFTP_OPTIONS="--secure --create" I al

Security Onion on the Antsle

My Setup of Security Onion on the Antsle: Recently my IDS box, an Intel Atom D2500 Fanless Mini-ITX PC, D2500CCE, died. Truth be told, I think it came from the factory in a bad state, as I originally thought I had a bad graphics driver, but I then noticed that, after much troubleshooting, it wasn't a driver issue at all. The box just sometimes wouldn't boot up correctly with video. It seems heat related, something like not enough thermal paste on the CPU, as after it is powered off for a while it is more likely to boot than when it is warm. Along with that issue, this box maxed out at 4GB of RAM (only has 2 memory slots, each of which will only take a 2GB card max) and had a single processor, so it was under powered for Security Onion. So, I decided to quit limping along on P.O.S. boxes, and buy a little more heavyweight box for my networked IDS. Security Onion requires a minimum of 8GB of RAM, and 4 cores per their specs page https://github.com/secur
