NAME
       massagevendor - convert the ethernet vendor codes master list to arpwatch
       format

SYNOPSIS
       massagevendor vendorfile

DESCRIPTION
       massagevendor is a program that converts a text file containing ethernet
       vendor codes into a format suitable for use by arpwatch(8) and
       arpsnmp(8).  The input vendorfile is a master text file containing vendor
       codes. The output is sent to stdout.  Each line of the vendorfile is
       expected to have a six digit hexadecimal vendor code followed by spaces
       followed by the name of the manufacturer.

       All ethernet devices have a unique identifier which includes a vendor
       code specifying the manufacturer of the device. In normal operation
       arpwatch(8) and arpsnmp(8) use the file ethercodes.dat to report this
       vendor code.  massagevendor is used to generate the ethercodes.dat file
       from text files containing these vendor codes.

       Locations where an ethernet vendor codes master text file can be obtained
       are given below.

FILES
       /var/lib/arpwatch - default location of the ethernet vendor list
       ethercodes.dat - file containing the list of ethernet vendor codes

SEE ALSO
