I see them too, but, what is really interesting, 
SRC_PORT == DST_PORT, so, packets are going from 1524 to 1524.
Besides of 1524 to 1524 I see a lot of packets (usually with
SYN, or SYN+FIN flags set) to port 21 from 21 (or 22-22)
Amount of those packets is increasing from day to day and it
affects all servers I'm looking at. 
Now it doesn't look like an individual with hping2 or sth,
it's rather some kind of worm-like tool.
Strange, since it's making signature-based NIDS life simpler... :)
