Introduction
In many cases using MRTG in a basic configuration to monitor the volume of network traffic to your server isn’t enough. You may also want to see graphs of CPU, disk, and memory usage. This chapter explains how to find the values you want to monitor in the SNMP MIB files and then how to use this information to configure MRTG.

This tutorial describes how to set up database replication in MySQL. MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.

Advanced Policy Firewall (APF) is an iptables(netfilter) based firewall system designed around the essential needs of today’s Internet deployed servers and the unique needs of custom deployed Linux installations. The configuration of APF is designed to be very informative and present the user with an easy to follow process, from top to bottom of the configuration file. The management of APF on a day-to-day basis is conducted from the command line with the ‘apf’ command, which includes detailed usage information and all the features one would expect from a current and forward thinking firewall solution. APF is developed and maintained by R-fx Networks: http://www.rfxnetworks.com/apf.php

Today I had implemented NIC bounding (bind both NIC so that it works as a single device). We have two Custom servers that need setup with Nvidia MPC55 NIC. Idea is to keep server accessible from both NIC without using any other method.
