One of the things that the GCIA study has taught me is that being able to monitor the network your computer is on is a critical necessity to maintaining a secure network. Corporate environments can set up IDS devices to monitor traffic however monitoring doesn’t work unless you have proper connectivity to what you want to monitor. Unfortunately, most of us don’t have central wiring in our house and expensive managed switches that can set up span sessions with which to monitor traffic in transit.  In this HOWTO, I will cover how to build your own monitoring connection that you can use on your own network to monitor traffic without breaking the bank. This article is first in a three part series on how to build your own home IDS for monitoring your network traffic. Look for the other two sections soon!

Well, the annual gift-giving season has drawn to a close and now we are left with retailers trying to get rid of all that extra stuff that thy have left over in their inventories.  Of course as a hardware geek, I’m always on the look out for another great hack. While at my CVS I came across a Sylvania netbook device for under $100. Even better, I got mine as an open box for only $30 making it an awesome find.  Read further to discover what this little beastie’s hiding under its hood. (continue reading…)

Dead Dockstar Resurrected with JTAG!

by on Sep.08, 2010, under Embedded devices, Hardware, How-To's, Linux

Hey, I never said I was a graphics designer.  This was created in MS Paint after 15 minutes searching for a zombie icon and a JTAG icon or an angel I could slap JTAG over.

The reason I haven’t written any more about my fun with the Dockstar was that due to an unfortunate set of circumstances I was left with a bricked dockstar. (read: I did something stupid.)  After performing a lot of research and thanks to a bunch of people over at the PlugApps.com Forum site who helped me, I was able to get it running.  Read more for a complete list of what you will need including how to build an adapter and where to get the needed JTAG kit.

Squirrelcage blower keeps small form factor PCs cool

by on Aug.14, 2010, under Embedded devices, Hardware, How-To's

Squirrel cage fan cooling. Not chuck squirrels through fans at nuclear reactors.

As long as there has been electronics, there has been the problem of how to keep them cool.  Unfortunately, the problem gets more complex the smaller that computers get and what works for one PC might not work for others.  This is clearly the obstacle to overcome when trying to cool down a settop box.  Read more to find out how I was able to pull it off very well for a little over $10 in parts and still maintain all my hair.

Seagate Dockstar: Add an accessible serial port

by on Jul.21, 2010, under Embedded devices, Hardware, How-To's

Ok, so not long after I published the article on  the hardware teardown of the Seagate Dockstar, I couldn’t help myself  so I started working on things to do with this device.  I did a lot of research in regards to the capabilities of the Dockstar, including being able to push a customized Linux OS on the device.  Once I saw the article at Hackaday that covers exactly how to replace the OS, I knew I had to do it for myself.  There are two ways to perform this upgrade however in order to capture syslog output and to be able to get to the bootloader, a serial port is required.  Just about all of the sites will describe the pins needed to make the connection, however none of them detail how to do it very clearly and none of them address the issue of aesthetics.  Read on for my method of adding a serial port to the Dockstar without affecting the look of the device.

Hardware Porn: Seagate Dockstar teardown

by on Jul.14, 2010, under Embedded devices, Hardware Pr0n, Linux

Seagate LogoI was given a very interesting product by a friend of mine that happened to catch a good deal on woot.com a few days ago.  Apparently Seagate has made a network fileserver device for their Freeagent Go line of portable USB drives called the Freeagent DockStar. (I can only think that this is a play on Battlestar Galactica’s Baystar – a cylon “aircraft-carrier” of sorts.)  When I went to look for pictures online of the hardware, I was dismayed to find nothing about the inside of the little thing.  So here they are in all their exposed glory, the innards of the Seagate Dockstar.
