Hi James,

since I'm a noob on this list I'll answer the question to save the head 
guys typing.

You have almost the exact same setup as I have, except my Linux box is a 
dedicated Smoothwall which I added QoS to. I'm going to assume you want 
to keep that box as a normal multi-purpose box rather than reformat it 
to Smoothwall :-)

I wrote a set of instructions and a pretty decent script based on 
Wondershaper which will help you. Both are on my webserver at the 
following address:

http://www.ivan.hawkes.tv/contentitem.aspx?idY&ciid@2

There are a couple of easy to follow articles there which I put together 
based on the harder to read but more comprehensive stuff held on lartc. 
Now, my adsl-shaper script isn't going to do what you want since I took 
out the IP based stuff since it wasn't relevant to me, so just follow 
the general instructions but use wshaper as your shaping script instead 
since it does support IP based limiting.

You will need to customise the script to get your IP addresses in, but 
basically what you are looking to do is simply put him into his own 
queueing discipline with a max bandwidth limit attached, and let all 
other traffic go through some other qdisc.

It is important to note that this generally works well for outgoing 
traffic but is not particularly effective against incoming traffic since 
that is *pushed* onto your machine and it has no way to control this. If 
your flatmate is maxing your bandwidth with mp3 downloads maybe a quick 
slap might sort him/her out ;->

You can control incoming bandwidth much the same as outbound - but it's 
hard to keep latency low all of the time.

Are you able to selectively control incoming bandwidth? e.g. I have some 
BT's running sucking up all that good bandwidth and my incoming pipe 
gets saturated (it's 2MB, so this doesn't generally happen). How would I 
tell the BT streams to slow down while giving more priority to the 
important stuff? I know how to do it on egress, just not on ingress.

You can treat it a egress traffic coming from shaping box to LAN. So the 
marking/filtering should be no different. In the BT case, there is a 
project on sf.net called ipp2p which can mark it, it needs you to patch 
netfilter/kernel with connmark. I don't use it so can't tell you in detail.

Andy.
