Hi All,

I want to monitor a host who has a Linksys router, which after 24 hours or so 
from being power cycled gradually locks out.  All attempts to ping, httping, 
traceroute, fail.  Surprisingly, nmap shows:
=====================================
Host XX-XXX-XXX-XX.dhcp.kgpt.tn.charter.com (XX.XXX.XXX.XX) appears to be 
up ... good.
=====================================

Sometimes it may find an open port, sometimes not in which case it reports 
that all ports are filtered.  I assume from these tests that the problem lies 
with the router as opposed to the modem, otherwise I would get a connection 
refused/failed sort of message, right?  Is there a way to set up Nagios to 
monitor/compare both modem and router?  I am thinking along the lines of 
pinging the router as normal and when that fails repeatedly, to run a command 
to check the modem.  How should I go about setting this up?

PS.  Don't be shy to go into detail here, I'll probably need it.  :)

Mick
