/*
   * NETWATCH is based on some code from Statnet 
   * Statnet is protected under the GNU Public License (GPL2). 
   * Author: Jeroen Baekelandt (jeroenb@igwe.vub.ac.be)       
   * 27DEC95: Scot E. Wilcoxon (sewilco@fieldday.mn.org)     
   * NETWATCH is VERY loosely based on the code from Statnet... thanks out
   * to Jeroen and Scot...
   * 
   * NETWATCH allows a user (superuser) to monitor an ETHERNET and examine
   * activity on the network. Hostnames are highlighted in colours (for
   * those supporting them) to indicate activity on the bus network based on 
   * time ( less than 1 minute RED, less than 5 minutes YELLOW, less than 30 
   * minutes GREEN and otherwise BLUE). The monitor includes statistics on 
   * a) Transmitted and received packets b) Protocol of LAST packet (TX or
   * RC) c) LAST Communication partner (IP address)
   * 
   * The number of hosts capable of support is a function of memory. They
   * are stored in 2 doubly-linked lists (local and remote).
   * 
   * Screen updates take place 1 per second (unless a rare  lockout... when
   * linked list links are updating... in which case it displays in the next 
   * second)
   * 
   * Keyboard usage is admittedly limited (and a kludge... due to some
   * ncurses settings that need better tinkering) ->   Go forward to next
   * option <-   Go backward to previous option <UP>         Go back to
   * previous page (back 20 lines on most consoles) <DOWN>       Go forward
   * to next page (forward 20 lines on most consoles) c    Clear counters
   * for fresh counting n    Clear linked lists for new start
   * 
   * It is a simple program to execute for ETHERNET under LINUX. It assumes
   * that there is a "/etc/rc.d/rc.inet1" file for network configuration. If 
   * so, it checks for an "eth0" ifconfig and picks up the netmask from the
   * file. UPDATE: It actually looks at the /proc entry for device configuration
   * to get its info... if no /proc THEN it trys the config file (for OLD SL
   * systems)
   * 
   * For those with multiple "eth" interfaces, I am sorry it doesn't support 
   * both simultaneously.
   * 
   * AUTHOR:      G. MacKay E-MAIL:      mackay@gmml.slctech.org
   * 
   * P.S. Given the fact that I was sick for 3 days and decided to write
   * this code... forgive me for not writing beautiful code... (those that
   * know me, probably don't think my code is beautiful when I am healthy)
   * 
   * NEW CODE IS COPYRIGHTED to  G. MacKay   under  GPL
