net-check

net-check package is a pair of simple perl scripts that will monitor and report on your internet connectivity.

The scripts came about when my DSL provider repeatedly dropped the connections on a machine that was used exclusively as a dial-up gateway.

In addition, since I am spending $50 a month for my internet connection, I want to make sure I get what I paid for.

A Sample:

To: user@isp.net
Subject: Automated Network Checks Report

Last month, there were 64.25 hours of downtime out of 720 possible hours.
(There were only 2692 out of 2880 possible samples made.)
Last months ratio was 0.089 so your bill should be $45.53.
