Linux Disable / Remove All NFS Services

Posted on in Categories , , , , , , last updated 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?

CentOS / RHEL Configure Yum Automatic Update Retrieval and Installation

The yum command line tool is used to install and update software packages under RHEL / CentOS Linux server. I know how to apply updates using yum update command line, but I’d like to use cron to manually update packages where appropriate. How do I configure yum to install software patches / updates automatically with cron?
