Linux Disable / Remove All NFS Services

by nixCraft on August 16, 2009 · 7 comments· last updated at February 16, 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. 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

You need to run:

/etc/init.d/portmap stop
/etc/init.d/nfs-kernel-server stop
apt-get --purge remove nfs-kernel-server nfs-common portmap

See this tutorial for more info.

Actually there is no portmap file or directory under init.d
what i have is
# cd /etc/init.d/
#
# ls
alsa-utils hwclockfirst.sh udev
hwclock.sh module-init-tools udev-mtab
the one who designed the system told me that he allready hv disable the nfs settings. But then i m not getting the reason for problem.
also I dont have /etc/fstab file

my hp 4050n ntwroek printer doesn’t work with large images and certain pdf files in linux.. windows 7 it works flawlessly. I was impressed with Ubuntu’s printing , but it isn’t up to windows spec. It’s also a lot slower with my ntwroek printer.
