Hello,
really new to advanced linux routing, but I have managed to setup
something that sort of works for my needs.
I have a linux box with this configuration:
Internet - eth0 - eth1 - many users
I'm using a NAT to allow my users Internet access.
On some users, I wish to shape their download speeds as to not overload
our outside connection.
Here is what I do to shape them at 64k down: (only two users shown in
this example(but I have hundreds that will be shaped))
SIXFOUR=64
DEV=eth1
# clean up qdiscs
tc qdisc del dev $DEV root 2> /dev/null > /dev/null
tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 50mbit
# DELL
tc class add dev $DEV parent 1: classid 1:1 cbq rate ${SIXFOUR}kbit
allot 1500 prio 5 bounded isolated
tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip dst
192.168.0.199 flowid 1:1
tc qdisc add dev $DEV parent 1:1 sfq perturb 10
# TYR
tc class add dev $DEV parent 1: classid 1:2 cbq rate ${SIXFOUR}kbit
allot 1500 prio 5 bounded isolated
tc filter add dev $DEV parent 1: protocol ip prio 16 u32 match ip dst
192.168.0.133 flowid 1:2
tc qdisc add dev $DEV parent 1:2 sfq perturb 10
each user gets their own section.
This works great for downspeed only, but I also want to shape them at
64k up as well. I can't shape them on eth0, because by the time their
packets get to that interface, they've already been NAT'd to a different
address.
After lots of reading on the mailing list archive, it appears the best
way to handle this is to mark packets from each user, then on eth0 have
HTB or CBQ (really unsure which to use) shape each marked packet
accordingly. Currently, I'm matching by IP (u32?), so should I match by
fwmark instead?
Any help is really appreciated or even a sample script concept would
make the operation more clear!
Ron
