Hello,

the answer is pretty straightforward: get Wireshark, the most powerfull network sniffer and packet analyzer.

thank you for your reply.

i am not sure if the latest release is fully compatible with Mavericks. I did see posts online saying some not-working issues on Mavericks, how about now? do you have personal experience of using Wireshark on Mac?

You're right, the issues are caused by the absence of X11 which is not being shipped as integral part of Mac OS anymore.
I believe installing XQuartz will solve your problem, see here for download:

Explanation about X11/XQuartz see here:

Please let me know should you not be able to run Wireshark anyway.
Good luck

thanks heaps for the information Martin.

just wondering if there are other solutions which do not need additional software or add-ons for running on Mavericks or Yosemite...

Hello and sorry for the late reply...
Well, you asked for the BEST network sniffer/analyzer, which Wireshark with no doubt is :-)
But I understand you are maybe looking for something more straightforward to deploy and use. If this is the case, give a try to these two sniffers:
Packet Peeper
http://packetpeeper.org/
- It's free, it uses the same syntax as Wireshark does and if you are somehow new to the area of network analysis, you might appreciate simple and easy to use GUI.

Cocoa Packet Analyzer
http://www.macupdate.com/app/mac/24867/cocoa-packet-analyzer
- I don't have any experience with this one personaly, but it looks even more simplified.

If these still don't meet your requirements, please let me know what kind of information are going to digg exactly on your network, maybe I will be able to suggest some more specialized tool.
Regards

Martin
