I found in my syslog a large number of identd entries like this one,
beginning a fortnight ago:

There tend to be several listings for each IP address, clustered
together, with a wide variety of IP addresses overall. Sometimes the
first 2-3 quads are similar in different IP addresses.

Any ideas? Have I been cracked? :) (PS: I already know what it was; just testing for responses I get. :)
