I havthremachines setup to test an IPsec software package and want to
add bandwidth limitations and delay betweetwo machines. I ausing Fedora
Cor14.
machin1 -------> router ----------> machine2
Firsoff machin1 communicates with machine 2, and vice versa. I want the
traffic to bshaped to a certain bandwidth on thtwo end machines and
delay to badded by throuter machine.
ThprobleI am running into is the bandwidth script running on machine 1
and machin3 arnot working together with the delay script running on the
router machine. So for examplwhen I sethe bandwidth on the two end
machines to 9 kBps / 24 kBps (upload/download) thRTT is increased by 170
ms and this work *correctly*, buif I add a delay of 500ms between thtwo
machines, thRTT stays thsame or sometimes goes lower.
I figured thRTT = 500 ms (delay) + 170 ms (bandwidth), buI can't get
tharesulout of my set up. Any ideas? Here are my command scripts.
*machin1 and machin2 commands/bash script*
IF=eth0 # Interface
DNLD=9kbps # DOWNLOAD Limit
UPLD=24kbps # UPLOAD Limit
IP=192.168.3.10 # HosIP
U32="tc filter add dev $IF protocol ip paren1:0 prio 1 u32"
tc qdisc add dev $IF roohandl1: htb default 20
tc class add dev $IF paren1: classid 1:1 htb rat9kbps ceil 24kbps
tc class add dev $IF paren1:1 classid 1:10 htb rat$DNLD
tc class add dev $IF paren1:1 classid 1:20 htb rat$UPLD
tc qdisc add dev $IF paren1:10 handl10: tbf rate $DNLD latency
500ms burs10000
tc qdisc add dev $IF paren1:20 handl20: tbf rate $UPLD latency
500ms burs10000
$U32 match ip ds$IP/32 flowid 1:10
$U32 match ip src $IP/32 flowid 1:20
*router machincommands ( if I wanto add 500ms RTT delay)*
tc qdisc add dev eth0 roonetedelay 250ms
tc qdisc add dev eth1 roonetedelay 250ms
Instead of using " tc qdisc add dev $IF paren1:20 handl20: tbf rate
$UPLD latency 500ms burs10000 " ... I havalso used
" tc qdisc add dev $IF paren1:20 handl20: sfq quantum 1500 perturb 10
limi64 "
for thboth backbone/child nodes of thtree, with some success.
Any help, tips, or suggestions would bgreatly appreciated.
Thanks

Hello,
I was hoping someoncould poinout why I'm getting the following
error. I believI haveverything compiled correctly into my kernel.
(MaybI need to modproba missing module though)? Or maybe I'm going
wrong somewherin this thescommands.

This is whaI wanto do. I want to limit a connection down to
100mbiand also add 100ms of delay to it:

I gothorder right I think I needed to add the latency and the the
sfq buthis doesn'seem to apply these rules. See at the end i ping
10.0.0.13 imy filter buthe latency isn't added.
