I'm trying to deploy cosbench on centos. There are some scripts rely on nc -q which is an invalid parameter on Fedora
and RHEL. As a result whenever -q is used an error message is printed and nc fails.
one similar case reported on redhat, here is the thread: http://cosbench.1094679.n5.nabble.com/cosbench-on-RedHat-td13.html. Generally, different nc binaries are used on different linux distro, for redhat or centos, the TOOL_PARAMS parameter defined in "cosbench-start.sh" should be set empty, while ubuntu and debian need "-q 1".
