Need Help W/ Simple Packet Capture Code - Caesars_10th - Mar-07-2019
Hey all,
I need help writing a code that can capture packets (pcap) from a dedicated port. All I need is for the code to capture the packet, timestamp it using the
datetime module, and write it to a pcap or even a text file.I don't really know how to capture packets though. I am guessing I can use Scapy, PyShark, or PyPcap. I'm just hoping someone else out there knows a good deal about this.
I'm thinking:
time = datetime.datetime.now() packet = #capture command... f.write(str(time) + '\n' + str(packet)Does anyone know the capture command? Can it work like this?
I'm ok with doing a packet capture that saves all the packets to a pcap file for later use, I just need the timestamp to be from the
datetime module because I am reading serial data in using this time source.Thanks for the help!

do you need it in a python script?
wireshark: https://www.wireshark.org/
is excellent at capturing all network activity

Larz60+ I have used Wireshark! IT IS very awesome.However, I DO need to write a python code. I would like to record all my sensors using python.

you can search through these packages: https://pypi.org/search/?q=packet+capture
or if you want to do it from scratch:
