just to let everyone know that I installed a fresh ztncui on ubuntu 18.04 bare metal server minimal install following the instructions at https://key-networks.com/ztncui/ after the install, I had some errors with tunnelling via ssh, one of the errors was channel 2: open failed: administratively prohibited: open failed ztncui
I solved this by changing my sshd_config file to
after an ssh restart, I was able to open up the interface with
ssh -p ssh_port -f username@ip_address_of_server -L 3333:localhost:3000 -N
then http://localhost:3333/ show the controller interface.
I am now successfully running heavy media feeds using my own controller network setup, I hope someone finds this useful.
