Unable to run mahimahi with the command

[yue2388253]

Is the following command correct?

mm-delay 10 mm-link --cbr 48M 48M --uplink-queue="droptail" --downlink-queue="droptail" --uplink-queue-args="packets=160" --downlink-queue-args="packets=160" --log=bbr.log iperf -c $MAHIMAHI_BASE -p 5000 -t 30 -i 1 -Z ccp

Firstly, in my machine, mahimahi cannot regconize the parameter "--log=bbr.log". Should "--uplink-log" or "--downlink-log" be used instead?

Secondly, should the command " iperf -c $MAHIMAHI_BASE -p 5000 -t 30 -i 1 -Z ccp" be run with "mm-delay" in one command? As far as I understand, this command might be run inside the shell spawned by mahimahi? I assume that the version of mahimahi I use is different. However, the mahimahi is installed by "ccp-system-setup.sh" and "Makefile", which should have a same result with you.

The environment I use is: Ubuntu 16.10(with kernel 4.13).

Hello, thanks for your interest in CCP.

mahimahi cannot regconize the parameter "--log=bbr.log". Should "--uplink-log" or "--downlink-log" be used instead?

We submodule a fork of mahimahi. Please check that there is no issue with your PATH and using the correct mahimahi.

Secondly, should the command " iperf -c $MAHIMAHI_BASE -p 5000 -t 30 -i 1 -Z ccp" be run with "mm-delay" in one command? As far as I understand, this command might be run inside the shell spawned by mahimahi?

Yes, we want the iperf traffic to go through the emulated mahimahi link.

I followed the guide of README.md(with vagarnt and the Vagrantfile this repo contains). When I tried to make, there's a problem when it tried to make mahimahi. That was why I installed mahimahi manully before. The error is as following:

cd mahimahi && autoreconf -i
.ibtoolize:    error: AC_CONFIG_MACRO_DIRS([m4]) conflicts with ACLOCAL_AMFLAGS=-I m4
autoreconf: libtoolize failed with exit status: 1
Makefile:24: recipe for target 'mahimahi/configure' failed
make: *** [mahimahi/configure] Error 1

hm, on a clean vagrant VM and clone of this repo I am unable to reproduce your error:

vagrant@ubuntu1710:/ccp$ make

Are you running on windows? It seems there is a known problem with CRLFs. The following link may be helpful: https://stackoverflow.com/questions/47582762/ac-config-macro-dirsbuild-aux-m4-conflicts-with-aclocal-amflags-i-build-aux

Closing, please re-open if issue persists

Thanks for your help. These three following commands help solve this problem.

find . -name \*.m4 | xargs dos2unix
find . -name \*.ac | xargs dos2unix
find . -name \*.am | xargs dos2unix
