Bandwidth on demand ?

I'm running 2.4.7-10 (old I know) driving my 512/256kbps DSL line, I'd like
to try packet shaping.
I've got three workstations (running Windoze), one of them is used mainly
for downloads. What I'd like to do is restrict the download machine to half
the available up/down stream bandwidth when either of the other two PCs are
being used and then let it use all the bandwidth when the other stations
have been quiet for a few minutes.

Is it possible to setup bandwidth on demand like this with linux ? Can I use
my current kernel version ?

man tc

setup two classes:

1. for the download machine
2. for the rest.

give lower priority to class 1.
That way, any bw demand of 2 is satisfied first, and then only 1.

Ahh cheers for that, can't find any man pages but I've got the binary so
I'll find some online docs. Thanks again.

http://lartc.org/ is the best place to start. The wondershaper script is a
good starting point. There is also the Adv-Routing-HOWTO (same link) and the
ADSL-Bandwidth-Management-HOWTO you might like.

Also my script
