Linux Disable / Remove All NFS Services
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. I use my CentOS based server only to server web pages and nothing else. How do I disable NFS services under RHEL / CentOS / Fedora Linux?
You can easily disable NFS, which is a commonly used for sharing data and files between machines. However, its use opens many potential security holes. If NFS is not needed, improve the security by removing and disabling NFS. Open a command-line terminal (select Applications > Accessories > Terminal), and then type:
# chkconfig nfslock off
# chkconfig rpcgssd off
# chkconfig rpcidmapd off
# chkconfig portmap off
# chkconfig nfs off
Delete nfs-utils and portmap packages using the yum command:
# yum remove portmap nfs-utils
Debian / Ubuntu Linux Disable / Remove All NFS Services
Following packages are used to provide NFS client and server services under Debian / Ubuntu Linux:
- nfs-kernel-server – NFS server package.
- nfs-common – NFS support files common to client and server
- portmap – RPC port mapper.
Stop NFS Services
Open a command-line terminal (select Applications > Accessories > Terminal), and then type the following command top stop NFS client and server services as follows:
$ sudo service portmap stop
$ sudo service nfs-kernel-server stop
$ sudo /etc/init.d/portmap stop
$ sudo /etc/init.d/nfs-kernel-server stop
Delete nfs-kernel-server, nfs-common, and portmap packages using the apt-get command as follows:
$ sudo apt-get --purge remove nfs-kernel-server nfs-common portmap
