I thought this DIY LED Array was pretty sweet especially how you can simply echo text via the serial port to the device for display.

WiFi WRT54G –> Cush Yagi
I need a pigtail so I can connect my Yagi antenna to SkyNet
The Yagi has a N (F) connector and the WRT54GS has a RP-TNC connector. Heres what I ve found so far:

New Project?
Well the time has come and I have been looking for a new project. I think implementing WPA2 Enterprise complete with a RADIUS backend would be fun not to mention help secure the home network further (currently using WPA2/TKIP).
I’m not sure if I am going to ditch my Tomato firmware on the WRT54G v3 for openWRT or what. I need to see what kind of requirements the freeradius server has.
Some links Ive found so far:

Memory Forensics
Dumping out a image of the current memory set for further analysis seems to be a much better approach to finding hidden processes, open ports, etc.
http://sansforensics.wordpress.com/2008/11/19/memory-forensic-analysis-finding-hidden-processes/ is a good article on it.
In a nutshell www.mandiant.com/software/memoryze.htm provides a suite of tools. Once he image gets dumped, you can analyze it with analyze.bat which will generate a XML file that you can import into excel for analysis.
RedHat LVM Expansion Fiasco
Finally I figured out a procedure for resizing the LVM partition. A server’s /usr partition has been dangerously full for some time now so this has become a priority.
Procedure:
- Resize VHD with VhdResizer
- fdisk /dev/hda
Add a new primary partition (hda4 for this list) - Reboot
- Tell LVM about the new physical volume
pvcreate /dev/hda4 - Extend the volume group
vgextend VolGroup00 /dev/hda2 - Extend the logical volume to use the newly expanded space
lvextend -L 19G /dev/VolGroup00/LogVol00 - Resize the filesystem to use the new space
ext2online /dev/VolGroup00/LogVol00 - Optional – check the disk for errors
e3fsck -f /dev/VolGroup00/LogVol00
