Modem.pl is a small script that scrapes the Web
interface of a Motorola SURFboard cable modem for
various status conditions like signal strength and
signal to noise ratio. The results are sent to
STDOUT where they can be easily piped into a log
file. The modem values are also checked for
reasonable operating ranges. If the modem values
are outside of reasonable operating ranges,
results are also sent to STDERR. When run from a
cron job, modem.pl can be used to monitor the
condition of the cable service and notify someone
before conditions cause service interruptions.
