I am running OpenBSD 3.3 and I am logging a lot of things on my firewall. I am trying to follow somewhat the model that they wrote about on O'Reilly's site and everything dumps fine, but when I run tcpdump -r on the file I get one of 2 errors. tcpdump: fread: Undefined error: 0, or tcpdump: pcap_loop: truncated dump file. Anyone have an idea where that is coming from. Thanks in advance.
