Problem using systemctl cluster@

I'm trying to set up the systemctl cluster@ files to use zbalance_ipc to
balance a stream. In /etc/cluster/cluster-99.conf I have this:

-i p1p1 -m 2 -n 2 -g 2 -c 99

I copied /lib/systemd/system/cluster@.service to
/etc/systemd/system/cluster@99.service. When I try to start it I get an error
from systemctl saying that the service didn't start.

If I do this:

zbalance_ipc /etc/cluster/cluster-99.conf

I get the help output with all the options to the zbalance_ipc program, so it
doesn't like something in the cluster-99.conf file. If I run zbalance_ipc with
the options in the cluster-99.conf file on the command line it works.

I'm using version 7.5.0-2747.

Correction: We're using the RPM package pfring-7.4.0-2768.x86_64. I was
looking at the GIT repo code, which is version 7.5.0-2747.

The problem with not being able to get zbalance_ipc to read it's options from a
file appear to be some bad code in PF_RING/userland/examples_zc/zutils.c. This
patch fixes it for me.

# diff -u zutils.c.orig zutils.c

if(argument[0] != '\0')

}
}

It wasn't replacing all the spaces with "=", and the NULL strtok to get the
next token was then taking the entire line up to the newline as the next token
instead of picking the next token up to the next "=".

Hi Mike
please use one option per line, as in the example below:

-c=99
-i=p1p1
-n=2
-m=2
-g=2

Ok, thanks. I'll admit I missed the "one per line" part in the docs, but I
don't see anything about using the "=".
