Description of problem:
Whether I generate multicast packets from nc, socat, or syslog-ng,
wireshark/tshark detect a UDP CHECKSUM failure.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. nc -u 18.104.22.168 12345
2. /usr/sbin/wireshark, and capture the identified packets
3. type something at the nc prompt
wireshark / tshark claims that the packet contains a UDP CHECKSUM failure.
No checksum error is detected.
I highly suspect that the kernel is generating the udp checksum, not the
applications. However, here are the versions of the applications that were used
as well as the kernel:
The only checksum problem I'm aware of is described here
is this the same problem?
No. I've also captured this when the packets are generated from another machine.
Wireshark was updated to 0.99.6 release. Please retest the issue with the latest
