Another picture from a chain mail :). My friend, Shashi, forwarded this via e-mail. Sarcastic look into communications in the corporate world. Not sure which publication this is from, so apologies in advance if this looks like palgarism. Click on the image to view a larger and legible image.

My friend passed on this picture from a e-mail thread.. I would love to meet the person managing this network :). Imagine having to trace a cable…

HOW TO : Install Wireshark on Windows 7
[UPDATE] Wireshark works without any issues as of version 1.2.3. This release includes WinPcap 4.1.1, which has support for Windows 7 and 2008. Looks like the issue was with the drivers not being signed digitally.
I recently upgraded my laptop to Windows 7 RC from the beta version I was testing earlier. As part of installing my standard set of tools, I tried to install Wireshark (open source network capture tool), and ran into an error due to the UAC security settings. Essentially, Windows was blocking the install of WinPcap (network capture driver). I solved it by enabling compatibility mode on the install executable. Here are the steps to install Wireshark on Windows 7.
- Download the install file from http://www.wireshark.org/download.html
- Right click on the install file (I happened to download the 64 bit install) and click on properties
- In the properties window, click on the compatibility tab and change the option for “Run this program in compatibility mode for” to “Windows Vista (Service Pack 2)” and click on OK. Here’s a screenshot for reference

- Right click on the install and click on “Run as Administrator”
- Make sure you choose the option to install the NPF as a service during the install prompts. This will allow all users on the machine to use Wireshark without admin privileges.
P.S : WinPCap is apparently going to come out with a new version soon that is compatible with Windows 7.
HOW TO : Convert mpg files to flv format using ffmpeg
For my documentation. Here is the command line parameters, I used to convert a video file in mpg format to flv (flash video) format using ffmped (open source format converter)
ffmpeg -i Original_Video.mpg -deinterlace -ar 44100 -r 25 -qmin 3 -qmax 6 Converted_Video.flv
I will post details on where to get software and such, when I have time :).
HOW TO : Improve performance on Samba
Adding the following options to the [Global] section in the samba (open source software providing windows compatible file sharing for *nix operating systems) will most likely speed your throughput
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=8192 SO_RCVBUF=8192
The receive and send buffer seem to do the trick.
