Nice to have a FREE, recently developed Cocoa packet sniffer for OS X. It's quite usable, and useful. One might think that because it has "Cocoa" in the name, that it must be a UI masterpiece; it's not. The "New Capture" dialog box has a stop and start button, neither of which are labeled. You have to rest your mouse over them and wait for a tooltip to appear to know what's what. Some features I would like to see added are 1.) the ability to search for text inside of packet payload and 2.) the ability to select ONLY hex or ONLY text in the packet contents pane. Anyway... Cocoa Packet Analyzer is off to a nice start. I'm thankful to the developers and I'm looking forward to its future improvements.

Have you considered integrating dtrace scripts into your data gathering process with this tool? soconnect_mac.d is exceptionally useful and there are some others enumerated at: http://dtrace.org/blogs/brendan/2011/10/10/top-10-dtrace-scripts-for-mac-os-x/ I find the usefulness of these to be quite extreme in debugging and finding information that does not usually lend itself readily, even through normal packet analyzation. A number of useful scripts from the DTrace Book can be found at: http://www.dtracebook.com/images/dtbook_scripts.tar.gz

Works well, and a useful tool to have at hand. I also use WireShark, but for quick packet captures, I prefer CPA. I very much appreciate developers who put out utilities like this without charging--value that can't be beat.

Pretty nice application but cannot find any capturing interface on a MBP with Lion. Any clue? Am I missing anything?

Nice! Not as feature complete as WireShark, but it sure beats firing up X11 if you need to sniff some packets! :) If the missing WireShark features could be added (follow conversation, protocol hierarchy, etc etc), I'd never fire up WireShark again.

Download site overwhelmed? Try http://bit.ly/crMYgS This is from that "other" Mac software update site, not the developer at http://www.tastycocoabytes.com/cpa/ Someone else needs to mirror this.

Awesome. Works like a charm. Easy and clean. And MacOS native. I really prefer this over the WireShark distribution, which requires X11 and has a pretty bad GUI. For my needs, CocoaPacketAnalyzer is the best choice.

Awesome, new version works a lot smoother, would freeze up with only 100 packets captured, now it can handle a thousand and decode in a second, awesome work !
