Debian / Ubuntu Linux Disable / Remove All NFS Services

in Categories , last updated May 3, 2017

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.
