My enviroment is like this...
FTP SERVER
1------|
|-----------eth0-----eth1---------||| My FTP Client||||
FTP SERVER
2------| (NAT
Server)
I want to mark the flow 0x88 from FTP Server 1 and mark 0x98
from FTP Server 2
When TOS's value is 0x88 then give it 1Mbit, 0x98 is
3Mbit
So my script is:
-----------------------------------------------------------------------------------------------------
INDEV="eth1"
EDEV="eth1" tc qdisc add dev $INDEV handle 1:0 root dsmark indices 64 set_tc_index tc class change dev $INDEV parent 1:0 classid 1:2 dsmark mask
0x3 value 0x88
tc class change dev $INDEV parent 1:0 classid 1:3 dsmark mask 0x3 value 0x98 tc filter add dev $INDEV parent 1:0 protocol ip prio 4 u32
match ip src \
140.92.61.20 flowid 1:2 tc filter add dev $INDEV parent 1:0 protocol ip prio 4 u32 match ip src \ 140.92.61.40 flowid 1:3 tc qdisc add dev $EDEV parent 1:0 handle 3: cbq bandwidth 10Mbit avpkt 500 tc class add dev $EDEV parent 3:0 classid 3:1 cbq bandwidth 10Mbit rate \ 1Mbit allot 1514 weight 100Kbit prio 8 maxburst 20 avpkt 500 isolated bounded tc class add dev $EDEV parent 3:0 classid 3:2 cbq bandwidth 10Mbit rate \ 3Mbit allot 1514 weight 300Kbit prio 8 maxburst 20 avpkt 500 isolated bounded tc filter add dev $EDEV parent 3:0 protocol ip prio 4 u32
match ip tos \
0x88 0xfc flowid 3:1 tc filter add dev $EDEV parent 3:0 protocol ip prio 4 u32 match ip tos \ 0x98 flowid 3:2 ---------------------------------------------------------------------------------------------------- I found that it can really modify my TOS value, but cannot
shap with 1Mbit or 3Mbit.
If I use u32 and parameter is "ip src 140.92.61.x", then
it can works.(shap with the correct bandwdth --> 1Mbit or 3Mbit
)
At least I use iptables and tc to combind and it finally
works (mark and shape at the same time....and correctly).
But my problem is iptables can only modify TOS with 5 kinds of
value...and AF num have 12 values....
How can I do with AF num????
