[LARTC] tc&htb

[Eddie]

Hi all.
I'm very new to Linux and the whole traffic shaping thing.
Now this is what I've got.A 128Kbit line on eth0 and a 100+ network on
eth1.The mail server is on the internal network(eth1 side).

This is what I want.
They run banking software that uses port 15000-15010.I want the bank
ports and if I'm going to ssh INTO the box to get all bandwidth,that is
128Kbit.Then I want the internal users limited to 96Kbit for web,32 for
mail in and out and 10Kbit for other stuff.I also want them all to share
bandwidth if not use(banking is not done most of the time but if it is
it should get the most)

I got this far and have no idea,I've been reading advance routing and
traffic control,but as the song goes,I'm not the sharpest tool int the
shed. 

This is what I've got so far(taken from 
15.10. Example of a full nat solution with QoS)
My main problem,if this is right,is with the filter.I don't know how
Please help me because I'm thinking traffic control is a myth?
Thanks Eddie

Your tc commands are ok.  For the filters, you can use the u32 filter that can 
match on port and or ip address or the fw fliter so you can iptables to 
classify the packets.
For some examples, see www.docum.org
