Default [Snort-users] TCP Flags & MySQL

I have a Snort sensor logging to a MySQL database which is front-ended by a
commercial application that allows for packet payload retrieval.

This weekend, the system recorded a large number of "TCP port 0" alerts, and
as expected it didn't record a payload. However, it did record tcp_flags
and tcp_win. However, I am having difficulty interpreting the raw values in
the tcphdr table into usable data. Can someone point me to a doc that
explains these values, or if I tell you that the tcp_flags values I see most
often are 2 and 18, can you tell me which flags are set?

Thanks,
PaulM
