ThinLinc Testdrive Config Interface
-----------------------------------

Before you can test thinlinc you have to create a user and
set the hostname, your instance will be visible under. Normally
this might be the hostname of the machine where you are running docker.

docker exec my-demo-docker tlcfg add-user myuser mypassword

docker exec my-demo-docker tlcfg add-ssh-user myuser "public ssh key"

docker exec my-demo-docker tlcfg set-hostname \$(hostname -f)
