Hello,
I have an issue where RYU pcaplib.Writer() isn’t writing full packets.
Ive created a RYU PCAP Writer Object as described here.
https://github.com/osrg/ryu/blob/master/ryu/lib/pcaplib.py
<https://github.com/osrg/ryu/blob/master/ryu/lib/pcaplib.py>
self.pcap_writer = pcaplib.Writer(open('mypcap.pcap', 'wb’))
However, when I tcpdump the resulting pcap, it shows that the packets are all
truncated at 62 bytes.
I’ve adjusted the snaplen=4294967295 and the issue is still the same.
Any suggestions would be greatly appreciated.
tcpdump -r mypcap.pcap …
