+The arpwatch package contains arpwatch and arpsnmp.  Arpwatch and
+arpsnmp are both network monitoring tools.  Both utilities monitor
+Ethernet or FDDI network traffic and build databases of Ethernet/IP
+address pairs, and can report certain changes via email.
+
+Install the arpwatch package if you need networking monitoring devices
+which will automatically keep track of the IP addresses on your
+network.

+README.ethercodes
+=================
+
+This file contains some specific instructions to complete the
+installation of arpwatch on Slackware.
+
+1) After installing the arpwatch package 
+----------------------------------------
+
+1.1) Change current location to the arpwatch working directory:
+
+     # cd /var/lib/arpwatch
+
+1.2) Download newest MAC addresses database:
+
+     # wget http://standards.ieee.org/regauth/oui/oui.txt
+
+1.3) Convert it into ethercodes.dat format using script included in arpwatch source:
+
+     # ./massagevendor oui.txt > ethercodes.dat
+
+1.4) Remove unnecessary database file:
+
+     # rm -f oui.txt
+
+1.5) Congratulations, you have just created ethercodes.dat file with the newest MAC adresses.

++massagevendor \- convert the ethernet vendor codes master list to arpwatch format
++.SH SYNOPSIS
++.na
++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.
++.LP
++Locations where an ethernet vendor codes master text file
++can be obtained are given below.

+':' following the base package name, and the '|' # on the right
+side marks the last column you can put a character in.  You must #
+make exactly 11 lines for the formatting to be correct.  It's also #

+arpwatch: arpwatch (Monitoring tools for tracking IP addresses on a network)
+arpwatch:
+arpwatch: The arpwatch package contains arpwatch and arpsnmp.  Arpwatch and
+arpwatch: arpsnmp are both network monitoring tools.  Both utilities monitor
+arpwatch: Ethernet or FDDI network traffic and build databases of Ethernet/IP
+arpwatch: address pairs, and can report certain changes via email.
