Sep 012011

Today i’m glad to have a Guest post from DarkDuck, i read frequently his blog where i’ve found a lot of well done reviews on many different Linux distributions.

Pidgin: your favourite Internet Messenger or Power of Plugin

Communications are very important nowadays.

But sometimes there are so many ways to communicate that people lose tracks: what, where and how.

If we look at the world of instant messaging, there are 1001 protocol in the world: ICQ, QQ, GTalk, MSN to name a few. Most of them have their own clients which you can use standalone. But soon you’ll get lost between them. Isn’t it easier to use single messaging client which supports multiple messaging systems and protocols? Of course it is!

That’s time for our today’s hero to come on stage. Please meet! Pidgin!

Pidgin is multi protocol instant messenger developed by open source community.

pax_britannica Pax Britannica it’s a One-button real-time strategy that puts you in control of a deep-sea “factory ship” that is immediately under attack. One button gives you the power to deploy an attack force of your own: Try to destroy your enemies before they destroy you.

The game can be played with one player versus the computer, or choose the best option and play it with 3 friends head-to-head.
It’s an open source game, developed with Lua and it’s fun with highly atmospheric sounds and music.

This is the second and last part of my article about building a distributed monitoring solution with Nagios, you can find part 1 here

Central Configuration

Now you know all you need to know to set up service checks on the slaves and send information from the slaves to the master.

A benefit of a master/slave configuration is the ability to centrally configure all the Nagios nodes, both master and slaves. There are many ways to do this.

One of my favorite ways to manage distributed Nagios configuration is to use a version control system (VCS) such as Subversion. In this setup you store all the configurations under the VCS (which is a good practice anyway, to keep your configuration file with a version number and a change history). The various Nagios sites each have their own directories where they can put their files; I suggest a setup like this:

Why and how build a distributed monitoring solution with Nagios – Part 1

This is an article of mine first published on Openlogic/Wazi

With Nagios, the leading open source infrastructure monitoring application, you can monitor your whole enterprise by using a distributed monitoring scheme in which local slave instances of Nagios perform monitoring tasks and report the results back to a single master. You manage all configuration, notification, and reporting from the master, while the slaves do all the work.

This design takes advantage of Nagios’s ability to utilize passive checks – that is, external applications or processes that send results back to Nagios. In a distributed configuration, these external applications are other instances of Nagios.

Thanks to James for his guest post regarding the development of Web sites with open source tools.

The web today is a hugely diverse environment. Much of this diversity and exponential growth is underpinned by software that has been developed by the open source community and is available free of charge in many cases. Take the website design industry. The vast majority of web servers house a Linux platform running Apache server and a MySql database. Web designers can be very grateful for having an alternative to the Microsoft platform, which had higher costs associated with its use especially in the earlier days as many may remember.
