spykhanat.py

Convert pcap (capture network) on yaml file to see communication between server and client.

Usage

sudo tcpdump -i [networkd card] -w [Pcap output]

ex.: sudo tcpdump -i eth0 -w capture-2020-11-28-17-37-57.pcap

Extract information

python3 spykhanat.py -m [localization msg.xml] --yaml [Yaml Output file] -w [localisation database.xml] -p [Pcap input] --filter-host-service='[Ip address: Port server khaganat]'

Ex.: python3 spykhanat.py -m ~/khanat/khanat-opennel-code/code/ryzom/common/data_common/msg.xml --yaml capture-2020-11-28-17-37-57.yml -w ~/khanat/khanat-opennel-code/code/ryzom/common/data_common/database.xml -p capture-2020-11-28-17-37-57.pcap --filter-host-service='127.0.0.1:47851'
