# Some try-outs with Python and network adaptor low-level communiation
|
|
|
|
## Installation / Preconditions
|
|
Tested with windows10
|
|
|
|
1. Install python (windows automatically launches the installer if you type „python“ into the search field of the task bar)
|
|
2. Wireshark is already installed, this includes the pcap driver, which is necessary for low-level-network-interaction
|
|
|
|
Attention: There are (at least) three different python-libs available for pcap:
|
|
- Libpcap
|
|
- Pylibpcap (But: only Python2)
|
|
- Pypcap (recommented on https://stackoverflow.com/questions/63941109/pcap-open-live-issue)
|
|
- Pcap-ct (https://pypi.org/project/pcap-ct/)
|
|
|
|
python -m pip install --upgrade pcap-ct
|
|
This is fighting against the Libpcap-installation, so we need to deinstall the second:
|
|
python -m pip uninstall libpcap
|
|
Then again install pcap-ct, and finally add in the libpcap\_platform\__init__py the missing is_osx = False.
|
|
|
|
Now, in the IDLE shall 3.10.6, the import works:
|
|
import pcap
|
|
sniffer = pcap.pcap(name=None, promisc=True, immediate=True, timeout_ms=50)
|
|
addr = lambda pkt, offset: '.'.join(str(pkt[i]) for i in range(offset, offset + 4))
|
|
for ts, pkt in sniffer:
|
|
print('%d\tSRC %-16s\tDST %-16s' % (ts, addr(pkt, sniffer.dloff + 12), addr(pkt, sniffer.dloff + 16)))
|
