VGA over Cat5e


Requirement One:  We have a IP-based security system, which I would like to monitor from our workout room.  (if the dogs bark I'd like to know if there is someone at the door or not)

Requirement Two:  My wife wants to watch TV from our workout room, and the cable jack is on the opposite side of a finished basement, so getting it to the other side of the room is a non-starter. 

Requirement Three:  She wants to be able to watch workout-videos as well, and we would like no cables or boxes at all in the workout room---Just the TV on the wall. 

Constraints:   The only thing on the wall where my wife wants the TV is an Ethernet Jack and an outlet. 

Solution: 


This nifty little converter will convert VGA to Cat5e, then Cat5e back to VGA.  This was a pretty expensive kit, but it will pump audio and video from our security system PC, which has a video tuner card for cable TV, and a DVD player for movies, all over one simple Cat5e cable.   So I tried it, and it works fine with one exception... The monitor (yes, it's a monitor, not a TV) will blink occasionally when it feels a power fluctuation.  For instance, if someone comes in and turns on the lights, the monitor will blink.   But I actually think this is a monitor artifact more than the converter artifact.  Here is a screenshot.


Look Ma!  No cables!

To watch TV or movies or the security system you have to pump it from the PC with the VGA converter attached, but that was solved with a simple VGA switch box.   When there is nobody in the workout room the security system is on the PC.  When one of us goes to the workout room, we put the PC to what we want to see, flip the monitor switch, and have a entertaining, or secure workout.

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
