[mirror-admin] Rate Limiting on our mirror server

[Paulo Licio de Geus]

We had to live off this script for a couple of years, consistently keeping external traffic at the required 25 Mbps cap during working hours. It was done by one of my students, Arthur Castro, and our system is Gentoo.

Poorly commented, of course:-), but the usage is "shaping on | off", and our local network is 143.106.0.0/16, which of course was exempted from restrictions.

Hope this helps.
