I have installed newton fwaas devstack by referring the following link for local.conf https://docs.openstack.org/developer/horizon/ref/local_conf.html
I got an error during installation soon after "tempest installation" in the process and installation was stopped.
Then I have followed the following commands 1) chown -R stack devstack 2) chmod 770 devstack 3) cd devstack 4) ./clean.sh 5) ./stack.sh
By executing above commands installation is completed and I have got ip for dashboard. But when I am trying to check firewall list, rules its giving authentication error. First I did " ./openrc admin admin " in terminal and then the link I have followed for firewall CLI command is below. https://wiki.openstack.org/wiki/Neutron/FWaaS/HowToInstall
Kindly let me know that is their any command to check whether FWaaS plugin is installed or not.
