Attached is a quick short summary of traffic my server ( xx.xx.xx.xx )
has been bombarded with lately.  It's a short dump from tethereal.  I
can't seem to figure it out - just tons and tons of traffic coming
from a source port of 80 to seemingly random dest. ports.  Can someone
help me identify this?

Thanks!

I wonder if it is a port scan, 'cause what would be the reason for scanning ports above 1024?

Does the pattern repeat after hours/days ? I mean does "the host
211.7.246.248 *always*
sends a src 80 dest 3509 SYN,ACK packet" after a few hours/days ? If
there is a pattern, then we can be certain of some automation.
