Python wrapper for tshark, allowing python packet parsing using wireshark dissectors
Python wrapper for tshark, allowing python packet parsing using wireshark dissectors.
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. Tested on windows/linux.
Reading from a capture file:
import pyshark cap = pyshark.FileCapture('/tmp/mycapture.cap') cap >>> <FileCapture /tmp/mycapture.cap (589 packets)> print cap Packet (Length: 698) Layer ETH: Destination: BLANKED Source: BLANKED Type: IP (0x0800) Layer IP: Version: 4 Header Length: 20 bytes Differentiated Services Field: 0x00 (DSCP 0x00: Default; ECN: 0x00: Not-ECT (Not ECN-Capable Transport)) Total Length: 684s Identification: 0x254f (9551) Flags: 0x00 Fragment offset: 0 Time to live: 1 Protocol: UDP (17) Header checksum: 0xe148 [correct] Source: BLANKED Destination: BLANKED ...
Reading from a live interface:
capture = pyshark.LiveCapture(interface='eth0') capture.sniff(timeout=50) capture >>> <LiveCapture (5 packets)> capture <UDP/HTTP Packet>
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:
packet['ip'].dst >>> 192.168.0.1 packet.ip.src >>> 192.168.0.100 packet.src >>> 192.168.0.100
