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
