I looked at the packets after doing a -dvr just for my PC and there simply is little there that looks at all like what the TCPDUMP process captured (virtually no payloads like you see in the pcap file). would the Checksum problem explain all the discards you noted? The "bad chk sum" from the statistics showed just 326 events for .025%. That number to me looks very small then as it is not even 1%. If you want me to rerun with -k none option again, I will do that. Should I do any kind of other logging at the same time or use other options to help diagnose?
Turn off all rules except the file-identify category, run with the configuration file that I pointed to in my previous email. Add `-k none`.
Run with -b in the command line (to output to pcap file), see what you get from there.
Sounds like something isn't right somewhere.
