No Video Displaying For D-Link DCS-3220 Surveillance Camera

Earlier this week I brought some security cameras from my house to the computer shop to hookup not only for security but also so we could make some funny clips about what happens in the store and on the sidewalk outside of the store. I ended up bringing 4 cameras which included a D-Link DCS-3220 and three D-Link DCS-950G’s. The D-Link DCS-3220 is a much nicer surveillance camera than the D-Link 950G’s however it doesn’t have wireless capabilities like the DCS-950G. The first camera I attempted to get working was the DCS-3220 but almost immediately I ran into issues which made me think I had damaged the camera bringing it to the shop.

Upgrade Google Chrome To Google Chrome Beta Version

I have been using Google Chrome for quite sometime and believe it to currently be the best all around browser. The browser is easily the most lightweight mainstream browser available and it appears to be gaining ground on the other popular browsers including FireFox, Safari, and Internet Explorer. There are still certain web sites and hardware that has internal browsers that require you to use FireFox or IE however that list continues to become shorter. Anyhow the current stable version of Google Chrome is 7.0.517.44 and I wanted to upgrade to the latest beta version which is Google Chrome version 8.0.552.28.

Remove Unwanted Start Up Programs from Mac OS X Leopard

As I have been using this new mac, installing software and getting things just the way I like them, I noticed that many times when adding a program it wants to add it self to the start up. Its funny because this is one thing in Windos which always bothered me and now it happening on my mac as well. Even when you uninstall software , system start-up files are still left behind and can still load up at boot time. You can speed up your boot time and reduce unnecessary system bloat from OS X by removing old system start-up files that you no longer need. if this is happening to you read on its very easy to edit the start up programs list.

Exclude An Entire Directory When Creating A Tar Archive

Last night I was creating some manual backups from a server including an entire web sites data files as well as the databases associated with that same web site. I decided to use the tar archiving utility to pack all of the files from the web site into a single file so it could be downloaded and stored easily. Use the information below to exclude a sub directory when creating a tar archive.

Script to Find All IP Addresses on a Internal Network

I was working on a presentation this morning and as I was writing I realized I did not have a quick fast way to make a list of all the internal Ips on a LAN (Local Area network). Many of the tools I use including nmap, nessus and nexpose will accept a list of ips so  I decided to whip up a quick dirty shell script to get the job done.  I may clean it up in the future but for now it does its job. This is meant to work on Backtrack 4 but in its current state it will work on any Debian based distro. As always with any code found on the internet you use this at your own risk. Also I am sure this can be done better but like I said it was a 10 minute fix.
