Python wrapper for tshark, allowing python packet parsing using wireshark dissectors.
Extended documentation: http://kiminewt.github.io/pyshark
There are quite a few python packet parsing modules, this one is different because it doesn't actually parse any packets, it simply uses tshark's (wireshark command-line utility) ability to export XMLs to use its parsing. This package allows parsing from a capture file or a live capture, using all wireshark dissectors you have installed.

Python2 deprecation - This package no longer supports Python2. If you wish to still use it in Python2, you can:
- Use version 0.3.8
- Install pyshark-legacy via pypi
- Clone the pyshark-legacy [repo (https://github.com/KimiNewt/pyshark-legacy)], where bugfixes will be applied.
Looking for contributors - for various reasons I have a hard time finding time to maintain and enhance the package at the moment. Any pull-requests will be reviewed and if any one is interested and is suitable, I will be happy to include them in the project. Feel free to mail me at dorgreen1 at gmail.

Installation
All Platforms
Simply run the following to install the latest from pypi
Or install from the git repository:
Mac OS X
You may have to install libxml which can be unexpected. If you receive an error from clang or an error message about libxml, run the following:
You will probably have to accept a EULA for XCode so be ready to click an 'Accept' dialog in the GUI.
Usage
Reading from a capture file:
Other options
- param keep_packets: Whether to keep packets after reading them via next().Used to conserve memory when reading large caps.
- param input_file: Either a path or a file-like object containing either apacket capture file (PCAP, PCAP-NG..) or a TShark xml.
- param display_filter: A display (wireshark) filter to apply on the capbefore reading it.
- param only_summaries: Only produce packet summaries, much faster but includesvery little information
- param disable_protocol: Disable detection of a protocol (tshark > version 2)
- param decryption_key: Key used to encrypt and decrypt captured traffic.
- param encryption_type: Standard of encryption used in captured traffic (mustbe either 'WEP', 'WPA-PWD', or 'WPA-PWK'. Defaults to WPA-PWK.
- param tshark_path: Path of the tshark binary
Reading from a live interface:
Other options
- param interface: Name of the interface to sniff on. If not given, takesthe first available.
- param bpf_filter: BPF filter to use on packets.
- param display_filter: Display (wireshark) filter to use.
- param only_summaries: Only produce packet summaries, much faster butincludes very little information
- param disable_protocol: Disable detection of a protocol (tshark > version 2)
- param decryption_key: Key used to encrypt and decrypt captured traffic.
- param encryption_type: Standard of encryption used in captured traffic(must be either 'WEP', 'WPA-PWD', or 'WPA-PWK'. Defaults to WPA-PWK).
- param tshark_path: Path of the tshark binary
- param output_file: Additionally save captured packets to this file.
Reading from a live interface using a ring buffer
Other options
- param ring_file_size: Size of the ring file in kB, default is 1024
- param num_ring_files: Number of ring files to keep, default is 1
- param ring_file_name: Name of the ring file, default is /tmp/pyshark.pcap
- param interface: Name of the interface to sniff on. If not given, takesthe first available.
- param bpf_filter: BPF filter to use on packets.
- param display_filter: Display (wireshark) filter to use.
- param only_summaries: Only produce packet summaries, much faster butincludes very little information
- param disable_protocol: Disable detection of a protocol (tshark > version 2)
- param decryption_key: Key used to encrypt and decrypt captured traffic.
- param encryption_type: Standard of encryption used in captured traffic(must be either 'WEP', 'WPA-PWD', or 'WPA-PWK'. Defaults to WPA-PWK).
- param tshark_path: Path of the tshark binary
- param output_file: Additionally save captured packets to this file.
Reading from a live remote interface:
Other options
- param remote_host: The remote host to capture on (IP or hostname).Should be running rpcapd.
- param remote_interface: The remote interface on the remote machine tocapture on. Note that on windows it is not the device display name but thetrue interface name (i.e. DeviceNPF_..).
- param remote_port: The remote port the rpcapd service is listening on
- param bpf_filter: A BPF (tcpdump) filter to apply on the cap beforereading.
- param only_summaries: Only produce packet summaries, much faster butincludes very little information
- param disable_protocol: Disable detection of a protocol (tshark > version 2)
- param decryption_key: Key used to encrypt and decrypt captured traffic.
- param encryption_type: Standard of encryption used in captured traffic(must be either 'WEP', 'WPA-PWD', or 'WPA-PWK'. Defaults to WPA-PWK).
- param tshark_path: Path of the tshark binary
Accessing packet data:
Data can be accessed in multiple ways.Packets are divided into layers, first you have to reach the appropriate layer and then you can select your field.
All of the following work:
To test whether a layer is in a packet, you can use its name:
To see all possible field names, use the
packet.layer.field_names
attribute (i.e. packet.ip.field_names
) or the autocomplete function on your interpreter.You can also get the original binary data of a field, or a pretty description of it:
Decrypting packet captures
Pyshark supports automatic decryption of traces using the WEP, WPA-PWD, and WPA-PSK standards (WPA-PWD is the default).
A tuple of supported encryption standards, SUPPORTED_ENCRYPTION_STANDARDS,exists in each capture class.
