I strongly suggest using the HTB traffic scheduler. The Linux Advanced 
Routing Guide should help - http://lartc.org/ and http://www.tldp.org/

You'll find the HTB home page at http://luxik.cdi.cz/~devik/qos/htb/, 
it's well worth a read. IMHO HTB is much nicer than CBQ to work with, 
and it's integrated into (very) recent kernels.

I can send you a sample script I hacked out quickly, it's ugly, written 
for my 512/128k ADSL, and totally comment free, but it might be of some 
use. Oh, it's also hardcoded to my network - 4 primary hosts with static 
IPs assigned via DHCP, 192.168.0.{2,3,4,5} with the firewall (not 
included) as 192.168.0.1 .

Limitations: Hosts other than those hardcoded get the scraps from the 
bottom of the bandwitdth bucket ; doesn't help network /latency/ under 
high loads as much as I'd like (ie ssh interactive performance is still 
marginal when the link is maxed, but marginal is better than type a 
command then go for coffee); still not really tweaked to optimal 
performance.

Nonetheless, the link goes from so loaded that web page loads time out 
to fairly useable when the QoS rules are active. If only I could afford 
1.5Mbps ADSL, I'd give the housemate responsable for 99% of the load a 
fixed 512k and the rest of us the other megabit....
