massagevendor

.I vendorfile

.SH "DESCRIPTION"

.B massagevendor

is a program that converts a text file containing ethernet vendor codes

into a format suitable for use by

.B arpwatch(8)

and

.B arpsnmp(8).

The input

.I vendorfile

is a master text file containing vendor codes. The output

is sent to

.I stdout.

Each line of the

.I vendorfile

is expected to have a six digit hexadecimal vendor code

followed by spaces followed by the name of the manufacturer.

.LP

All ethernet devices have a unique identifier which

includes a vendor code specifying the manufacturer of the

device. In normal operation

.B arpwatch(8)

and

.B arpsnmp(8)

use the file

.I ethercodes.dat

to report this vendor code.

.B massagevendor

is used to generate the

.I ethercodes.dat

file from text files containing these vendor codes.
