# clientbot
|
||||
|
||||
Emulate Client (Python Script)
|
||||
|
||||
# spykhanat.py
|
||||
|
||||
Convert pcap (capture network) on yaml file to see communication between server and client.
|
||||
|
||||
## Usage
|
||||
|
||||
### Launch network capture
|
||||
|
||||
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'
|
||||
|
||||
### Analyze result
|
||||
|
||||
you can see the result in yaml output
|
||||
|
||||
Field:
|
||||
* packet : raw data
|
||||
* block_Client : data sent by client
|
||||
* block_Server : data sent by server
|
||||
* state : message docoded or partially decoded)
|
||||
* impulse : impulse message
|
||||
* impulseserver : message impulse server decoded
|
||||
* Message : Message analyzed (one line by block)
|
||||
|
||||
|
||||
Detail message format (ex.: <0:31> (Sint32) CurrentSendNumber => 42 : 00000000000000000000000000101010)
|
||||
<Position data> (Type) [Function] => Value : [Value in binary] [(optional) value real]
|
||||
* position data : Begin:End
|
||||
* Format data (Signed/Unsigned Integer, String, Number of bit)
|
||||
* Function (type of value, function in khaganat)
|
||||
* Value : value in integer
|
||||
* Value in binary
|
||||
* Value convert for khaganat (sometimes is keyword)
