Activate an interface without assigning an IP (Debian/Ubuntu)

Open-E Review, Not a Storage Server
About a year ago, a client needed a NetApp (NFS server), but the IPO wasn't there yet, and the startup's balance sheet was still in the Red. Needless to say after a few trials, we ended up with Open-E DSS because of budget constraints.
