Is the ORBIT testbed firewalled?
Yes. The nodes do not have direct access to the Internet. However, the machine used for initial login, “gateway.orbit-lab.org”, does. Recently, we also opened up the consoles for direct access from outside. e.g in order to access console for sandbox2, use ”’ssh user@console.sb2.orbit-lab.org”’. Since your home directory on gateway is also accessible via the testbed consoles, it is possible to upload and download from the Internet on “gateway.orbit-lab.org” and copy files to your nodes from the testbed console.
