While looking into all of the specifics of the screencapture application on Mac OSX Lion I came across some interesting information about Color Profile. The Color Profile is assigned to each image captured with screencapture and I assume other media utilities function in the same way meaning they use the color profile that was configured when the image was created. The Color Profile stands for ICC Profile or International Color Consortium Profile and specifies a configuration file or set of configuration details that include color attributes. As you can image not all monitors display colors in the same way the same as not all graphics cards output colors in the same way so the Color Profile assigns settings that can be adjusted to make colors or any form of graphics look different.
Alex and I rewired our entire network the other day with cat 6 cable and new gigabit switches. Once we got it all set up we decided to do some testing. One of the tests we ran was transfer speeds from our file server to our laptops. We were trying to determine the network linkspeed when all of a sudden I realized that I had no idea how to do this on my mac. We decided to figure it out, and when we did, we of course wrote a article to help every one else. Below I will outline the simple steps to view your link speed in Mac OSX.
Part of Wireless Assessments is always getting a visual view of your client set up. I am always looking for new ways to do this however the best way I have found is using a tool called GISkismet which was written by a guy I know named Jabra. I was getting ready for work this week and I decided to write a quick article on how to do this. All the tools are open source and available on the backtrack 4 cd except Google earth which you must install.
We have various scripts on a server that process files that are uploaded to a specific directory so we needed a way to monitor these directories and verify that all files are being processed. Once they are processed on our server they are moved to different directory so the file count should never get over a certain amount of files. The below script assumes that you have NRPE installed on the server so you can reference the bash script locally. Follow the directions below with some monitor modifications and you can monitor directories for the number of files with Nagios very easily.
This was not obvious to me, although it should have been because the message in the Display preference clearly says it.
