Have you considered linking against libpcap instead of shelling out
to tcpdump? As long as we have this lib installed on the runners
(likely?) that should be a bit cleaner than doing tcpdump.. WDYT?
I just checked the script building the root image for vmtest. [1]
It doesn't install libpcap.
If our approach is to capture the packets in a file, and let developers
download the file, it would be a simple and straight forward solution.
If we want a log in text, it would be more complicated to parse
packets.
Martin & Stanislay,
WDYT about capture packets in a file and using libpcap directly?
Developers can download the file and parse it with tcpdump locally.
