 |
|
sto cercando di sistemare il mio web/file/mail server con QoS per evitare che ogni tanto la mia modesta alice non si impalli completamente a causa di troppi kb/s richiesti in uscita.
ho seguito diverse guide e diversi howto ed e' stato facile riuscire a limitare il traffico della porta 80 (che nel mio caso e' quella da cui passa piu' traffico) ma non sono riuscito a risolvere un problema: limitare il traffico solo quando e' diretto verso la wan e non verso la lan.
ecco lo script:
| Code: |
#!/bin/bash
########################
# network device
DEVICE="eth0"
# tc executable full path
TC_EXEC="/sbin/tc"
# lan max upload speed
LANMAXSPEED="100000"
LIMIT="120"
########################
if [ "$1" = "--start" ]
then
${TC_EXEC} qdisc add dev $DEVICE root handle 1: htb default 10
${TC_EXEC} class add dev $DEVICE parent 1: classid 1:1 htb rate ${LANMAXSPEED}kbit
${TC_EXEC} class add dev $DEVICE parent 1:1 classid 1:10 htb rate ${LANMAXSPEED}kbit
${TC_EXEC} class add dev $DEVICE parent 1:1 classid 1:20 htb rate ${LIMIT}kbit
${TC_EXEC} filter add dev $DEVICE protocol ip parent 1:0 prio 1 u32 match ip sport 80 0xffff flowid 1:20
else if [ "$1" = "--stop" ]
then
tc qdisc del dev $DEVICE root
else
echo "Usage: trafficshaper { COMMAND }"
echo "Command: { --start | --stop }"
fi

ho provato a fare qualcosa di piu' complesso ma il risultato e' stato che non limitava un bel niente:
| Code: |
#!/bin/bash
########################
# network device
DEVICE="eth0"
# tc executable full path
TC_EXEC="/sbin/tc"
# lan max upload speed
LANMAXSPEED="100000"
# lan guaranteed upload speed
LANGUARSPEED="50000"
# wan max upload speed
WANMAXSPEED="256"
# wan guaranteed upload speed
WANGUARSPEED="128"
########################
if [ "$1" = "--start" ]
then
${TC_EXEC} qdisc add dev $DEVICE root handle 1: htb default 10
${TC_EXEC} class add dev $DEVICE parent 1: classid 1:1 htb rate ${LANMAXSPEED}kbit
${TC_EXEC} class add dev $DEVICE parent 1:1 classid 1:10 htb rate ${LANGUARSPEED}kbit ceil ${LANMAXSPEED}kbit prio 1
${TC_EXEC} class add dev $DEVICE parent 1:1 classid 1:20 htb rate ${WANGUARSPEED}kbit ceil ${WANMAXSPEED}kbit prio 2
${TC_EXEC} qdisc add dev $DEVICE parent 1:10 handle 10: htb default 101
${TC_EXEC} qdisc add dev $DEVICE parent 1:20 handle 20: htb default 201
${TC_EXEC} class add dev $DEVICE parent 10: classid 10:1 htb rate ${LANMAXSPEED}kbit
${TC_EXEC} class add dev $DEVICE parent 10:1 classid 10:101 htb rate $[50*$LANGUARSPEED/100]kbit ceil ${LANMAXSPEED}kbit prio 1
${TC_EXEC} class add dev $DEVICE parent 10:1 classid 10:102 htb rate $[50*$LANGUARSPEED/100]kbit ceil ${LANMAXSPEED}kbit prio 2
${TC_EXEC} class add dev $DEVICE parent 20: classid 20:1 htb rate ${WANMAXSPEED}kbit
${TC_EXEC} class add dev $DEVICE parent 20:1 classid 20:201 htb rate $[50*$WANGUARSPEED]kbit ceil ${WANGUARSPEED}kbit prio 1
${TC_EXEC} class add dev $DEVICE parent 20:1 classid 20:202 htb rate $[50*$WANGUARSPEED]kbit ceil ${WANMAXSPEED}kbit prio 2
${TC_EXEC} qdisc add dev $DEVICE parent 10:101 handle 101: sfq perturb 10
${TC_EXEC} qdisc add dev $DEVICE parent 10:102 handle 102: sfq perturb 10
${TC_EXEC} qdisc add dev $DEVICE parent 20:201 handle 201: sfq perturb 10
${TC_EXEC} qdisc add dev $DEVICE parent 20:202 handle 202: sfq perturb 10
${TC_EXEC} filter add dev $DEVICE parent 1:0 prio 0 protocol ip u32 match ip dst 192.168.1.0/24 flowid 10:101
${TC_EXEC} filter add dev $DEVICE parent 1:0 prio 0 protocol ip u32 match ip sport 80 0xffff flowid 20:201
else if [ "$1" = "--stop" ]
then
tc qdisc del dev $DEVICE root
else
echo "Usage: trafficshaper { COMMAND }"
echo "Command: { --start | --stop }"
fi

possibile che non si possa fare un semplice opposto di "match" sulla netmask, da aggiungere al "match" sulla porta?
