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

       /usr/share/arpwatch - default location of the ethernet vendor list
       ethercodes.dat - file containing the list of ethernet vendor codes
