Think about how DenyHosts works, the IP can only be added in two ways: one if it
appears in the log file it is watching in the last period, and two if it is
received by the sync function because it was reported in other places.  To be
added the precondition is that the IP is not already there.

I don't see the same problem, in fact the IP appears only once in
/etc/hosts.deny and 71 times in /usr/share/denyhosts/data/sync-received; so the
IP is being reported but denyhosts doesn't duplicate entries.

What could be wrong?  You don't give detailed information so the following are
_only_guesses_:

- The log file it is watching is in a non-standard format (no time-stamps
perhaps?) or corrupted.
- You have a corrupted hosts.deny and somehow denyhosts doesn't see that the
entry is already there.
- You have a corrupted denyhosts (what version are you using?) and it's not
working (you don't say if it catches other attempts for instance).

Do you have anything interesting in the denyhosts log?

Have you ran the program in debug mode?
