-d data_file - use this data file (defaults to ``physaddrwatch.dat'')
-s ds[,...] - use ``physaddr'' table in SQL database rather than a data file.
(Or in addition to a data file if ``-d data_file'' is specified as well.)
The specified value will be used as argument(s) to

This utility maintains a data file (e.g. ``physaddrwatch.dat'') containing three white-space seperated columns. These columns contain, in order, the IP or AppleTalk address, physical ethernet (MAC) or ATM address, and the date and time.
physaddrwatch locks its data file while polling each gateway. This prevents the file from becoming corrupt by having multiple processes attempt to write it simultaneously.
