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 Debian / Ubuntu Linux based server only to server web pages and nothing else. How do I disable NFS services under Debian or Ubuntu Linux?
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
OR
$ sudo /etc/init.d/portmap stop
$ sudo /etc/init.d/nfs-kernel-server stop
Delete Services
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

? nfs4 was designed with security in mind.
ok ok ubuntu
I have remove portmap service on my vps server. When I look at the network port status by “netstat -tunl ” it was showing port 794 and after remove portmap daemon the port number go away. Not my ethernet traffic so clean, I wondered if removeing the daemon will help memory a bit. Because I recognized when I was started my vps cleanly my vps’s memory was show 220.000 KB, after remove process 150.000KB. Just curies if anyone have a such experiences.
