This freeware can be used as a network forensic analysis tool that can detect the OS, hostname and the open ports of the host network by packet sniffing and by parsing a PCAP file. It can also extract transmitted files.
Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998.
Wireshark has a rich feature set which includes the following:
- Deep inspection of hundreds of protocols, with more being added all the time
- Live capture and offline analysis
- Standard three-pane packet browser
- Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others
- Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
- The most powerful display filters in the industry
- Rich VoIP analysis
- Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
- Capture files compressed with gzip can be decompressed on the fly
- Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
- Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
- Coloring rules can be applied to the packet list for quick, intuitive analysis
- Output can be exported to XML, PostScript®, CSV, or plain text

What is SharkFest?
SharkFest™, launched in 2008, is a series of annual educational conferences staged in various parts of the globe and focused on sharing knowledge, experience and best practices among the Wireshark® developer and user communities.
SharkFest attendees hone their skills in the art of packet analysis by attending lecture and lab-based sessions delivered by the most seasoned experts in the industry. Wireshark core code contributors also gather during the conference days to enrich and evolve the tool to maintain its relevance in ensuring the productivity of modern networks.

SharkFest Mission
SharkFest’s aim is to support ongoing Wireshark development, to educate and inspire current and future generations of computer science and IT professionals responsible for managing, troubleshooting, diagnosing and securing legacy and modern networks, and to encourage widespread use of the free analysis tool. Per Gerald Combs, Wireshark project Founder …“Wireshark is a tool and a community. My job is to support both”.
SharkFest GOALS
- To educate current and future generations of network engineers, network architects, application engineers, network consultants, and other IT professionals in best practices for troubleshooting, securing, analyzing, and maintaining productive, efficient networking infrastructures through use of the Wireshark free, open source analysis tool.
- To share use cases and knowledge among members of the Wireshark user and developer communities in a relaxed, informal milieu.
- To remain a self-funded, independent, educational conference hosted by a corporate sponsor.

Question or issue on macOS:
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?
Best Free Packet Sniffer
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.
