8-2-2005 One free Windows iptrace equivalent program is windump, which requires winpcap (Protocol CAPture). To download winpcap, go to http://www.winpcap.org and follow the "Downloads" link. When I installed this on cadev03, I got WinPcap 3.1 beta 4, which simply installed 6 files in the C:\Program Files\WinPcap directory. ------------------------------------------------------------- To get windump, start at http://www.winpcap.org/windump and and follow the Windump "download" link (not the WinPcap one) Today, I got Windump 3.8.3 beta, which is simply one file. Windows liked defaulting it to downloading this file to my "desktop", which on cadev03 since I was logged in as jasper, equates to C:\Documents and Settings\jasper\Desktop. ------------------------------------------------------------- The documentation for windump can be found at http://www.winpcap.org/windump/docs/manual.htm ------------------------------------------------------------- One simple way to run this is to get a DOS Command Prompt window, and cd "C:\Documents and Settings\jasper\Desktop" windump -t port 1433 but I couldn't make sense of the output I got, eg 70:0a:20:52:41:53 802.1b-gsap > 03:00:00:00:00:02 802.1b-isap ui/C len=180 Those 70 & 03 numbers look like MAC addresses, but 70:0a:20 isn't a known/assigned MAC address manufacturer (according to http://www.coffer.com/mac_find), and that 03-all zeros MAC address looks phony. I couldn't find what 802.1b was. There was something about it on google, but it was inside code & didn't make much sense. ------------------------------------------------------------- Another tool that is probably better that Mike downloaded, is BillSniff. It's presentation is more like what I'm used to. It requires WinPCap from http://winpcap.polito.it/install/bin/WinPcap_3_0.exe
