[LARTC] Simple Example isnt working (ssh/bulk traffic)

[LARTC] Simple Example isnt working (ssh/bulk traffic)

[Julius]

Hi,

the script below should allow to get ssh connections running well while 
downloading, but even the 100kbps (100kbyte/s?) doesnt work - can still 
download with 500+kb/s. Whats wrong?




INTERFACE=eth0

#clear all on $INTERFACE
tc qdisc del dev $INTERFACE root


tc qdisc add dev $INTERFACE root handle 1:0 htb default 15
#root qdics, allows borrowing for its children
tc class add dev $INTERFACE parent 1:0 classid 1:1 htb rate 100kbps ceil 
100kbps
#ssh qdisc
tc class add dev $INTERFACE parent 1:1 classid 1:5 htb rate 20kbps ceil 
100kbps prio 2
#other traffic
tc class add dev $INTERFACE parent 1:1 classid 1:15 htb rate 80kbps ceil 
100kbps prio 10
#filter ssh
tc filter add dev $INTERFACE protocol ip parent 1:0 prio 1 u32 match ip dport 
22 0xffff flowid 1:5
tc filter add dev $INTERFACE protocol ip parent 1:0 prio 1 u32 match ip sport 
22 0xffff flowid 1:5

are you mixing egress with ingress? (IMQ in that case)
What's you network-configuration (it's a router? what eths)?

And yes, kbps actually is kbyte/s, kbit for kbit/s.

If all should be setup right, what does
# tc -s -d class show dev eth0
say?

Bye,
 Andreas

ah, yes i did.

INTERFACE=ppp0

#alles löschen
tc qdisc del dev $INTERFACE root

tc qdisc add dev $INTERFACE root handle 1:0 htb default 15
tc class add dev $INTERFACE parent 1:0 classid 1:1 htb rate 11kbps
tc class add dev $INTERFACE parent 1:1 classid 1:5 htb rate 6kbps ceil 11kbps 
prio 2
tc class add dev $INTERFACE parent 1:1 classid 1:15 htb rate 5kbps ceil 11kbps 
prio 10
#ssh filtern
tc filter add dev $INTERFACE protocol ip parent 1:0 prio 1 u32 match ip dport 
22 0xffff flowid 1:5
tc filter add dev $INTERFACE protocol ip parent 1:0 prio 1 u32 match ip sport 
22 0xffff flowid 1:5



Network setup:

my pc ---- internet ---- router@home



I want to connect to router@home, traffic shaping is done on the router.
The router can do 120kb/s down and 14kb/s up. This works so far, have to test 
these settings for some time.
