[LARTC] double rule

[LARTC] double rule

[Petre Bandac]

I want to shape the traffic on the http port and further on shape it if the 
destination ip is on some network I specify

however, only the first rule is applied ... why ?

#http
$filtru prio 1 u32 match ip sport 80 0xffff flowid 1:11
#droop :-)
$filtru prio 1 u32 match ip src x.x.x.x  \
                match ip dst x.x.x.0/24 flowid 1:13

where classes are defined earlier as

$tc class add dev eth0 parent 1:1 classid 1:10 \
                htb rate 32kbit ceil 32kbit

$tc class add dev eth0 parent 1:1 classid 1:11 \
                htb rate 64kbit ceil 64kbit

$tc class add dev eth0 parent 1:1 classid 1:12 \
                htb rate 128kbit ceil 160kbit

$tc class add dev eth0 parent 1:1 classid 1:13 \
                htb rate 100kbit ceil 100kbit

and 

filtru="$tc filter add dev eth0 protocol ip \
                parent 1:0"


thanks in advance,

petre

Because you add both rules to the same parent.  When one rule is matched, the 
packet is put in the destination class and the other rule is never matched.  
Atach the second rule to class 1:11 with option "parent 1:11" and it should 
work.
