MASSAGEVENDOR(8)					      System Manager's Manual						  MASSAGEVENDOR(8)

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

       arpwatch(8), arpsnmp(8)

       Sources for ethernet vendor codes seen in the wild are
