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.

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:

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.

Today I’m glad to present you an article by James Hawkins.

As the heading of this article suggests, either you are a windows or a Linux user, you aren’t safe online. We (Linux users) were happy in the past thinking that running Ubuntu or Fedora would have saved us from an “infection”, but that is not the case anymore, today any Operating System whether Mac, Linux or windows, has his own weakness,related to his vulnerabilities. We know that windows pc’s had more vulnerabilities in comparison to any other O.S in the past, but the point is that every computer over the Internet could have its own exploits, its only a matter of finding those vulnerabilities and exploiting them.

nfuploader Back from vacation? now you’ll have probably a lot of photos and video to show to friends on facebook, but loading them by hand from the web interface is not exactly the easiest thing to do.

There is a small program that can help you: NFuploader, which allows you to load one or more images from Nautilus, but some are also used by Thunar the XFCE file manager, directly to Facebook.
