Cocoa Packet Analyzer is a native Mac OS X implementation of a network protocol analyzer and packet sniffer. It uses libPCAP for reading packet trace files and for capturing network traffic. Supports the Cocoa bundles technology for creating TCP/IP application layer protocol "Analyzer PlugIns".
MSWFUJOWDFFYC 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. (Version 0.47)
PHALERON The window shown on the screenshot does not open for me. No instructions found either. I assume all that will be in place by version 1.0, but for the time being, I could not test the product. (Version 0.42)
