Am trying to run flent in a network namespace and it won't work.
Seems to demand connection to the Internet for DNS.

The scenario is run net server in one namespace, and flent in another.
Forward packets out and route between vlan's on an external box
that is being tested.

It works for basic iperf but not flent.

# flent rrule -p all_scaled -l 300 --host=198.18.1.1 -t example -o example.png
Started Flent 1.2.2 using Python 3.6.9.
ERROR: Found no hostnames on lookup of rrule
