Comment 3 for bug 1741456

Now, I find if I use haproxy or I deployment network node on other computer which is no sahara_engine or sahara_api, this error will be hadppen, I think the command 'ip netns exec qrouter-fakerouter nc 10.0.0.2 22' will not exec, because there is no ip netns on the computer which sahara service run.
I find not only ssh but also http will exec the command(http port is 8080). but if I use the qdhcp namespace, I can exec the command correctly.
Could someone fix it ?
