[LARTC] tc filter

[LARTC] tc filter

[raz]

hello
my name is razvan and I'm from Romania

my problem is kinda' stupid but I have tried all the posible ways of
getting things to work an it still seems i'm missing something, maybe you
can help me
problem:
i have a routing server, that is the gateway to the internet for a network
and a file server the same time
so I want to allocate 90Mbit for file sharing and the 10 mbit for internet
trafic where 80.97.88.16/28 would have only 64kbit of downlink and
80.97.88.0/24 the rest.

what I wright is

tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 20 r2q 100

tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit ceil 100mbit
tc class add dev eth0 parent 1: classid 1:2 htb rate 1mbit ceil 10mbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 90mbit ceil 90mbit
tc class add dev eth0 parent 1:2 classid 1:20 htb rate 940kbit ceil 1mbit
tc class add dev eth0 parent 1:2 classid 1:21 htb rate 64kbit ceil 128kbit

tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src
80.97.88.1 flowid 1:10
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src
80.97.85.3 flowid 1:10
tc filter add dev eth0 protocol ip parent 1:2 prio 1 u32 match ip dst
80.97.88.16/28 flowid 1:12


but tc -s -d class show dev eth0 tells me that noting goes throuth 1:21

class htb 1:12 parent 1:2 prio 0 quantum 1000 rate 64Kbit ceil 128Kbit
burst 1680b/8 mpu 0b cburst 1762b/8 mpu 0b level 0
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)
 lended: 0 borrowed: 0 giants: 0
 tokens: 168099 ctokens: 88149

I appologize for cutting and pasting so much text but I just want to make
the situation as clear as posible for someone that wants to help me

thanks
raz

Replace:
> tc filter add dev eth0 protocol ip parent 1:2 prio 1 u32 match ip dst
> 80.97.88.16/28 flowid 1:12
with:
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst
80.97.88.16/28 flowid 1:21

Note that class 1:12 doesn't exists.

Look, it's 1:12 above!

[LARTC] tc filter

[doudouyam]

[-- Attachment #1.1: Type: text/plain, Size: 214 bytes --]

Hi,
Is it possible to make a filter with tc which exclude an IP like iptables ??

ex:
iptable -t mangle -A PREROUTING -i eth0 -d ! 192.168.1.222 -j MARK ...

I try the ! with tc but it doesn't work.
Thanks,
doude.

Not directly, but you can just match the address then follow it with a 
filter that matches everything else.
