Re: Anyone have the userguide's tc script and the corresponding ethloop input files?

Thanks a lot, it's really a good way, I'll try it!

This is the only script I found.
It uses monitor.pl that I use to get the counters. But you can also see the
original code from Devik in comments that uses ethloop. I hope this will
help you.
burst.sh is a script that creates the tc setup I want to test. client1 and
client2 are actually ttcp commands to generate traffic. So the script
launchs 2 programs to generate traffic, monitor.pl to get some counters,
kills the running ttcp programs, parse the output and use gnuplot to plot it.

# set -x
CEIL="1000kbps"

./burst.sh $CEIL

(sleep 3 ; ./client1 ) &
(sleep 6 ; ./client2 ) &

monitor.pl end= 30 sleep=500000
kill `ps -ef | grep ttcp | awk '{print $3}'`
kill `ps -ef | grep ttcp | awk '{print $2}'`
