Ping monitoring to Google DNS and Comcast DNS would probably be<br>

has more money :) )<br></blockquote><div><br><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;display:inline">Good point.

I would also consider having your modem and router logs relayed to a<br>
machine with an actual hard drive so you can review them. (You just<br>
need rsyslogd or syslog-ng to open a port and use filtering to dump the<br>
logs to their own files.)<br></blockquote><div><br><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;display:inline">Good idea - I will look into that. I should be able to get the router to do that - I had it's predecessor set up for that once<br><br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I would agree with Derek that it sounds like some of your hardware may<br>
be misbehaving and monitoring that hardware directly would be beneficial.<br>
<br>
By example, I have Uverse with static IPs but the modem performs<br>
connection tracking through the NAT tables even on those (dumb but<br>
true). The state table is not very large so occasionally something like<br>
a massive probe from the outside will fill the table and my external<br>
connections drop. Once the table entries expire away, everything comes<br>
back.<br>
<br>
I have OpenWRT on my router and use mrtg to monitor the traffic volume<br>
while its system logs are sent to another machine running syslog-ng<br>
where I can keep a window up running tail on that file. The modem has<br>
the same configuration for its logs but I can't run mrtg on it.<br>
