This will be a collection of scripts for the Huawei HG612.
You need to have unlocked it and restore the full HG612 firmware in order to use these.
At the moment, there's just a bash script which is a plugin for munin. See the munin site for information about plugins: http://munin-monitoring.org/wiki/plugins
With big thanks to the people who wrote the unlocking instructions at http://www.kitz.co.uk/routers/hg612unlock.htm
