Thanks.
Is that a GUI front-end?

Those tc commands do just that, but from the command line, and they're 
likely already with your distro.


There's also "tinker" (or "trickle") which I've not looked at.

Some further links for those wanting more of the story:

... and this stuff seems already to be in this 2.6 kernel...

Have fun,
