Question or issue on macOS:
Packet Peeper is a free network protocol analyzer (or ‘packet sniffer’) for Mac OS X. Its features include: TCP stream reassembly. Privilege separation. Simultaneous capture sessions. Filters, which may be defined at any time. Packet Peeper uses the same syntax as tcpdump and Wireshark (or any other program that uses the pcap library). Auvik is Best for intelligent analysis of network traffic. Auvik Networks is a Network.
I’m developing a website that uses SSL (connction to https) and I want to confirm that all the data sent is encrypted. Could anyone give me a good free packet sniffer on Mac OS that I could use?
Thanks!
How to solve this problem?
Solution no. 1:
It’s not as slick as Wireshark, but OS X has a built-in command line tool for capturing and displaying packets:
(the -A flag makes it display the packets’ contents as text, -s0 makes it capture entire packets not just the headers, -ien0 makes it capture on the first ethernet interface (generally, the wireless is en1), and port 80 makes it only capture traffic to/from port 80 (see the man page for more options for capture patterns.)
Solution no. 2:
Don’t forget Packet Peeper, WireShark is not so nice on Mac.

Solution no. 3:
Wireshark, or, Lion comes with one built in. Find it at /System/Library/CoreServices/Wi-Fi Diagnostics. I prefer Wireshark.
