Awesome article to run wireshark on Snow Leopard...

I found this article during my search to run Wireshark on snow leopard and this worked like a charm. I am extracting all the information from this article and posting it here so that if the link from Michael Garcie goes offline or not accessible, you still can refer to my link ...  :)

Getting Wireshark running on OS X Snow Leopard 10.6
Wireshark is every fly fisher who’s missing the fall brown run’s ubergeek’s favorite network protocol analyzer, both because it kicks main butt, and it’s free. With the recent upgrade to Snow Leopard, I finally found a need to upgrade. Then the trouble started (i.e. Wireshark didn’t work anymore). After doing a little research and scanning the support boards, I’ve got it running error free. But as the tips I used to get it that way are spread across the interwebs, I’m assembling the step-by-step here for the rest of you streamer-obsessed knuckleheads who are breaking fly rods over their knees as we speak Wireshark/Snow Leopard users who have just as little time on their hands as I do right now.

Step 1
Download Wireshark from here. Mount the .dmg file.

Step 2
Drag the Wireshark application icon to the handy dandy Applications alias the fine developers at Wireshark provided for you in that disk image. Then, open up the Utilities folder in the disk image, and drag the ChmodBPF folder into the StartupItems alias sitting below it. After that, open up a new finder window and navigate to /usr/local/bin. Open up the Command Line folder in the disk image (under /Utilities) and drag those contents over to /usr/local/bin. You’ll probably have to authenticate at that point, so do so.

Step 3
Open up a terminal window and type in the following commands:

cd /Library/StartupItems
sudo chown -R root:wheel ChmodBPF

You’ll probably be asked to enter an su password. Do so. Then exit terminal.

Step 4
Go to Applications and click on Wireshark. When the application opens you’ll probably see a another window open up along with it containing a bunch of errors. Close that window. Next, select Edit then Preferences from the Wireshark application window. Select Name Resolution, and click the Edit button next to “SMI (MIB and PIB paths”. Click the new button, and enter /usr/share/snmp/mibs/ in the little Directory Path popup window. Click Apply, and then Close.

Step 5
Exit Wireshark and restart.

All should be well in network protocol analyzer-ville.
