Hi All , My first message and I have a little problem with my FC6 box trying to block emule traffic using layer7 .
Here my network : Internet --------- ADSL Router ------------------- FC6 Box -------------------- Emule Box external ADSL : Dynamic Internal ADSL : 192.168.254.1 external FC6 : 192.168.254.3 internal FC6 : 192.168.253.1 Emule Box : 192.168.253.3 I guess that everything is ok with layer7 . Here my mangle rules . # iptables -t mangle -A PREROUTING -mlayer7 --l7proto edonkey -j MARK --set-mark 2 # iptables -t mangle -A PREROUTING -m mark --mark 2 -j LOG --log-prefix "PREROUTING MARK : " iptables -t mangle -A FORWARD -mlayer7 --l7proto edonkey -j MARK --set-mark 2 iptables -t mangle -A FORWARD -m mark --mark 2 -j LOG --log-prefix "FORWARD MARK : " The output from log is : Jun 8 14:18:46 fs-linux kernel: FORWARD MARK : IN=eth0 OUT=eth1 SRC= 203.91.83.127 DST=192.168.253.3 LEN=180 TOS=0x00 PREC=0x00 TTL=105 ID=18725 PROTO=TCP SPT=51674 DPT=4662 WINDOW=16944 RES=0x00 ACK PSH URGP=0 Jun 8 14:18:48 fs-linux kernel: PREROUTING MARK : IN=eth0 OUT= MAC=00:06:4f:47:ad:e0:00:0f:3d:cc:29:e0:08:00 SRC=200.209.170.138 DST= 192.168.254.3 LEN=139 TOS=0x00 PREC=0x00 TTL=115 ID=18002 DF PROTO=TCP SPT=1476 DPT=4662 WINDOW=65535 RES=0x00 ACK PSH URGP=0 Jun 8 14:18:48 fs-linux kernel: FORWARD MARK : IN=eth0 OUT=eth1 SRC= 200.209.170.138 DST=192.168.253.3 LEN=139 TOS=0x00 PREC=0x00 TTL=114 ID=18002 DF PROTO=TCP SPT=1476 DPT=4662 WINDOW=65535 RES=0x00 ACK PSH URGP=0 Jun 8 14:18:51 fs-linux kernel: PREROUTING MARK : IN=eth0 OUT= MAC=00:06:4f:47:ad:e0:00:0f:3d:cc:29:e0:08:00 SRC=200.244.104.10 DST= 192.168.254.3 LEN=40 TOS=0x00 PREC=0x00 TTL=117 ID=7042 PROTO=TCP SPT=50675 DPT=4662 WINDOW=64952 RES=0x00 ACK FIN URGP=0 Jun 8 14:18:51 fs-linux kernel: FORWARD MARK : IN=eth0 OUT=eth1 SRC= 200.244.104.10 DST=192.168.253.3 LEN=40 TOS=0x00 PREC=0x00 TTL=116 ID=7042 PROTO=TCP SPT=50675 DPT=4662 WINDOW=64952 RES=0x00 ACK FIN URGP=0 So it's look like mark is working . So now I use the cbq.init script with that configuration : cat /etc/sysconfig/cbq/cbq-0002.emule_in DEVICE=eth0,100Mbit,10Mbit RATE=3Kbit WEIGHT=1Kbit PRIO=5 BOUNDED=yes ISOLATED=yes MARK=2 cat /etc/sysconfig/cbq/cbq-0002.emule_out DEVICE=eth1,100Mbit,10Mbit RATE=3Kbit WEIGHT=1Kbit PRIO=5 BOUNDED=yes ISOLATED=yes MARK=2 that generate this tc codes . /sbin/tc qdisc add dev eth0 root handle 1 cbq bandwidth 100Mbit avpkt 3000 cell 8 /sbin/tc class change dev eth0 root cbq weight 10Mbit allot 1514 /sbin/tc qdisc del dev eth1 root /sbin/tc qdisc add dev eth1 root handle 1 cbq bandwidth 100Mbit avpkt 3000 cell 8 /sbin/tc class change dev eth1 root cbq weight 10Mbit allot 1514 /sbin/tc class add dev eth0 parent 1: classid 1:2 cbq bandwidth 100Mbit rate 3Kbit weight 1Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 3000 bounded isolated /sbin/tc qdisc add dev eth0 parent 1:2 handle 2 tbf rate 3Kbit buffer 10Kb/8 limit 15Kb mtu 1500 /sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 200 handle 2 fw classid 1:2 /sbin/tc class add dev eth1 parent 1: classid 1:2 cbq bandwidth 100Mbit rate 3Kbit weight 1Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 3000 bounded isolated /sbin/tc qdisc add dev eth1 parent 1:2 handle 2 tbf rate 3Kbit buffer 10Kb/8 limit 15Kb mtu 1500 /sbin/tc filter add dev eth1 parent 1:0 protocol ip prio 200 handle 2 fw classid 1:2 Can anyone explain me what is wrong . Why I cannot shape this traffic ???? Any help will be appreciated . Best Regards , Saulo Silva
