Debian / Ubuntu Linux Disable / Remove All NFS Services

Posted on in Categories , last updated September 7, 2011

NFS was not designed with security in mind, and has a number of weaknesses, both in terms of the protocol itself and because any NFS installation must expose several daemons, running on both servers and clients, to network attack.
