CommuniGate Pro: Cluster Load Balancers – The DSR/DR is the preferred Load-Balancing method for larger installations. When this method is used, each Server is configured to have the VIP (Virtual IP) shared addresses as its local IP addresses. This allows each Server to receive all packets directed to the VIP addresses, and to send responses directly to the clients using the VIP as the "source" address. The servers should not respond to the arp requests for these VIP addresses. Instead the load balancer responds to these requests, and thus all incoming packets directed to the VIP addresses are delivered to the load balancer, which redirects them to Servers. When redirecting these incoming packets, the load balancer sends them directly to the Server MAC address, without changing the packet destination address, that remains the VIP address.

Configuring DSR on the Alteon load balancers | Remsys – As per Wikipedia, load balancing is a technique to spread work between two or more computers, network links, CPUs, hard drives, or other resources, in order to get optimal resource utilization, maximize throughput, and minimize response time. Usage of multiple components with load balancing, instead of a single component, may increase reliability through redundancy. DSR is a way for outbound traffic to bypass the load balancer, sending traffic directly to the default router of that network.
FreeIPA – FreeIPA is a Red Hat sponsored open source project which aims to provide an easily managed Identity, Policy and Audit (IPA) suite primarily targeted towards networks of Linux and Unix computers. FreeIPA can be compared to Novell's Identity Manager or Microsoft's Active Directory in that the goals and mechanisms used are similar.

apache2-mpm-itk – apache2-mpm-itk (just mpm-itk for short) is an MPM (Multi-Processing Module) for the Apache web server. mpm-itk allows you to run each of your vhost under a separate uid and gid—in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. mpm-itk is based on the traditional prefork MPM, which means it's non-threaded; in short, this means you can run non-thread-aware code (like many PHP extensions) without problems. On the other hand, you lose out to any performance benefit you'd get with threads, of course; you'd have to decide for yourself if that's worth it or not. You will also take an additional performance hit over prefork, since there's an extra fork per request. [ via http://bastian.rieck.ru/blog/posts/2012/secure_owncloud_installation/ ]

Introducing Pysa – Reverse your servers’ configurations! | MadeiraCloud – We are excited to announce the Alpha release of our new open-source configuration reverse engineering tool: Pysa Pysa aims to help anyone who wants to replicate an existing configuration and not simply clone the entire machine. It can be use to migrate configurations from one computer to another (as physical machines to virtual clouds), backup existing configurations, or for any other migration purpose.

Master & Slave PowerDNS – LinuxManage.com – In this short tutorial we will show you how to configure powerdns running as master and slave. For this tutorial purpose, master powerdns host will have ip address 192.168.56.3 and hostname ns1.example.com, slave ip: 192.168.56.4 and hostname: ns2.example.com
Sendmail relay configuration on AIX | Leave No Bit Unturned – This document describes how to set up a Sendmail e-mail gateway or relay which will be able to process incoming mail and route it to different mail servers based on domain information. The routing table is based on the Sendmail mailertable feature instead of the usual MX record based routing. This will come handy when there is a need to route mail internally in a different way than externally.
