Idea behind this article is to give a stepwise Howto to newbie in JBoss Application Server, I felt its need when I first started working on JBoss and found it difficult to get such a Howto that can give me comprehensive steps for installing and configuring JBoss Cluster.

The Article covers JBoss 4.2.1 and JRockit 5.0-27.3 cluster on Centos/RHEL 4.4 using VMware.

Cheers!

Welcome

In this howto we will install 2 bind dns servers, one as the master and the other as a slave server. For security reasons we will chroot bind9 in its own jail.
Using two servers for a domain is a commonly used setup and in order to host your own domain you are required to have at least 2 domain servers. If one breaks, the other can continue to serve your domain.

Say, you’ve got an SVN for your OpenSource project and would like to mirror it to some remote location that hosts opensource projects (such as SourceForge.net or dev.java.net). I’ll skip the phase of an account and project registration and assume you’ve already got your credentials and SVN repo url. I also assume you are on Debian or Ubuntu and your SVN is up and running under Apache httpd.

This tutorial shows how you can set up a network-attached storage server with FreeNAS. FreeNAS is based on the FreeBSD operating system and supports CIFS (samba), FTP, NFS, RSYNC, SSH, local user authentication, and software RAID (0, 1, 5). It comes with a powerful web interface and uses very little space on the hard drive - about 32MB.

I do not issue any guarantee that this will work for you!

Preface:  

Some times, we are required to resolve our Internal domains at local nameserver while External (Internet) domains from ISP’s nameserver. There are different solutions to this problem, but in this howto, we are going to solve it through configuring combination of caching-nameserver and BIND 9 together.

Theory Behind Caching-Namerserver and BIND 9: 

Caching-Nameserver is a type of nameserver that will resolve a web address (domain name) from its next or master DNS, and will keep those entries in cache, after first time resolution it will resolve DNS queries locally, untill its TTL (Time To Live) is expired. 

BIND 9 is used to resolve domain resolution queries from it own database, as it is SOA (Start Of Authority).

.htaccess is papular name of this configuration modification file, you can change this default name by changing AccessFileName parameter in apache config file. i.e.

AccessFileName .anyname

In this howto, I will take a dumy scenario of two parallel level subdirectories and will implement password authentication on both of them.

In this howto we will learn how to build a Dynamic DNS Server. Normally when we configure DNS, we use static entries to resolve any FQDN. If we are using DHCP in our network which gives dynamic IPs to every computer that turns on or requests one, then it is not possible to configure DNS statically. For that we should configure our DNS with DHCP in a manner that whenever a computer gets a new IP, its FQDN will be automatically updated with the new IP in DNS.

1 Installation of Packages

Fedora Core 4 contains a DNS (Bind) and DHCP (dhcp) packages in its CDs. You can install it from the Fedora Core 4 CDs or download it from the internet using following command.

yum –y install bind bind-chroot bind-utils bind-libs caching-nameserver dhcp

1 Overview

This document describes how to attach modems to a Linux box and allow it to receive calls to connect users to the network. Its like being your own ISP (Internet Service Provider). If your Linux box is connected to the Internet, then the users will also be connected to the Internet. Your Linux box becomes a router. This is also known as RAS (Remote Access Services) in the Microsoft world. In the Linux world its called PPP (Point to Point Protocol).
