The openstack CLI tools are available to all hosts which reside inside the cloud. The recommended entrypoint to start using these clients is to open an ssh client, and ssh to "skyhigh.hig.no" using your NTNU username and password. From that shell all openstack clients are available; and access to all floating IP's within the cloud.
For CLI client access to stack.it.ntnu.no, SSH to either login.ansatt.ntnu.no or login.stud.ntnu.no (depending on you affiliation). The clients are available here.
It's also possible to run the CLI client driectly from Windwos. HOWTO guide here
Authentication
A user needs to be authenticated before he/she can use the openstack clients. this is done by setting multiple environment-variables in the shell defining username/password/projectname+id and so forth. It is recommended to use the script which is downloadable from the webinterface to set these variables.
