My guess is that replies to NOPs are arriving but being discarded
because their HMAC does not match either the password or the transaction
ID used by the DCC client.  There should be no password and that `cdcc
info` output agrees.  Thus either something is confused and thinks 
there is a password or the transaction IDs.

I'd first 
  1. cdcc info> map.txt
  2. mv /var/dcc/map /var/dcc/map.bad
  3. cdcc "new map; load map.txt"

If that fixes the problem, it would be interesting to compare
the old and new map files.

If not, perhaps the dccproc (or dccm?) a.out is trashed and could
be fixed by re-installing.
