Hello all,
Probably a silly problem as a result of lack of understanding here, but I'm
having some trouble with a supposedly simple shaping script here.
I have a bunch of IPs on an interface tun0 (VPN clients) which I'm trying to
rate limit to 5Mbps default, and then set externally by a script to 1Mbps or
10Mbps. All traffic goes out of eth0 from the clients - no routeback.
Shaping doesn't seem to be working correctly (user's upload is ~250KB/sec +
when it's meant to be rate limited to 1Mbps - ip ending .6 - the
corresponding class id is 1:6 in the below/attached logs)
Here's my tc script:
### tun0 setup
tc qdisc add dev tun0 root handle 1: htb default 99
tc class add dev tun0 parent 1: classid 1:1 htb rate 100mbit
tc class add dev tun0 parent 1:1 classid 1:99 htb rate 100mbit
### eth0 setup
tc qdisc add dev eth0 root handle 1: htb default 99
tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit
tc class add dev eth0 parent 1:1 classid 1:99 htb rate 100mbit
### shaping for users, 5Mbps down, 5Mbps up. default for beta test
for q in `seq 2 30` ; do
d=`printf "%x" $q`
### tun0
tc class add dev tun0 parent 1:1 classid 1:$q htb rate
5Mbit
tc filter add dev tun0 protocol ip parent 1:0 prio 1 u32
match ip dst 208.100.21.$q flowid 1:$q
### eth0
tc class add dev eth0 parent 1:1 classid 1:$q htb rate
5Mbit
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32
match ip src 208.100.21.$q flowid 1:$q
done
attached is the output of "tc -s -d class show dev tun0" and "tc -s -d class
show dev eth0", as well as "tc -s -d filter show dev eth0" (they were
fairly long).

Several users were using Bittorrent at the time - including .6.
Can anyone shed some light on how best to fix this problem, or any
additional information you may need?
Thank you,
Jan
