Hi all

I got the following message.

UDP: bad checksum. From 67.204.26.203:1054 to 66.49.0.97:55290 ulen 43
UDP: short packet: From 67.55.92.141:23801 30368/46 to 66.49.0.0:24617

What is this meaning?

Possibly a switch somewhere between the src and dst systems is doing fast-forward switching, and collisions are causing partial packets to be transmitted?
