My opinion is that unknown scanner was hoping to meet one of those admins who still use remote port of TCP/UDP packet as filter in
their firewall rules (like this: "ipfw allow tcp from any 21").

Subject: port 21
my kernel message showing:
Connection attempt to TCP 202.184.64.29:21 from
213.137.2.195:21
anyone can explain why 213.137.2.195 can use port 21 to connect
to my ftp port but not random port above 1024?
