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.

RORO01 How can anybody give five stars to a beta application? Just thank the developer for thinking of us and be patient. Hopefully the time will come for a five star rating.

PHILIPZ Not sure if I understand your comment. So you can only give good ratings if it is a non-beta, no matter how good/reliable it is?

HENRIKTEKNIK If MacUpdate provides a voting function during applications' beta stages, then of course the users should able to post their review scores, should they feel for it.

Ratings during an app's beta stage, should reflect the reviewer's experience with that app, at that particular moment in time. If an app is good, it's good. I don't necessarily think it stinks just because it's in a beta stage. Mind you, some developers tend to keep their apps in beta stage for very long, sometimes even if it's to be considered final. If that's the scenario with an app that I like, then I usually won't hesitate from giving it the rating I think it deserves.

RORO01 Five stars are for perfect applications whatever they are. Normally beta applications are not perfect by definition.

PETER DA SILVA Why would a TCPDump (or rather libpcap) GUI "not be a real sniffer"?
(Version 0.46.5)

IWAMOTO 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 !

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.

JENSF CPA is able to open pcap files. so you first need a pcap file. you can create one e.g by using tcpdump in terminal (tcpdum -w file.pcap)

BOZO CLOWN Just choose File / New Capture from the menubar when the app starts and it'll appear. Arguably, the app should do this automatically when it starts.

MKLLOW Nice job, its nice to see such a powerful tool natively on mac os x
