Logwatch on my laptop tells me

Listed by source hosts:
 Dropped 30 packets on interface eth0
   From 192.168.0.40 - 30 packets to tcp(38575)

192.168.0.40 is a mail/file/print server running SL.  It may also be
relevant that the laptop has fstab mounts to data areas on the server.

I feel that there must be some way I can trace what is actually
sending those packets, so that I can make an assessment, but I've no
idea how/where to look.  I see that it's an unallocated address, so
I've no pointer at all.

Where should I start looking?
