Filed under
HowTos

This tutorial shows you how to configure BIND9 DNS server to serve an internal network and a external network at the same time with different set of information. To accomplish that goal, a new feature of BIND9 called view is used. As a tutorial it'll walk you through the whole set up, but initial knowledge of BIND and DNS is required, there are plenty of documents that cover that information on the Internet.

1 The problem

It is a typical problem in organizations that are growing that they have to resolve two problems at once:

*To have a DNS server for the internal network of the company because long ago there were already too many computers to remember their IPs1 and even too many computers to maintain a set of host files2.

*To have a DNS server for the external servers, for external clients, etc.

two solve this problems at once become a bigger problem when the growing organization can't supply more resources than one DNS server3.

The Tiny Internet Project, Part I

As LJ readers well know, Linux drives many of the technologies we use every day, from smart TVs to Web servers. Linux is everywhere—except most homes and classrooms. That's a problem if we want to help breed the next generation of engineers and computer scientists. In fact, if teenagers (or any other group of curious individuals) want to learn about Linux, they often must rely on a geeky friend or parent willing to show them the way. This three-part series seeks to change that by offering a way for anyone to learn about Linux by building what is essentially a tiny, self-contained Internet. Using old equipment and free software, you'll build a private network (with your own domain name), build Web sites, set up an e-mail server, install and use a database, and set up a Linux distro mirror.

Don’t be a stranger to GIMP, be GIMP…

I can try and do more coding, more code reviewing, revive designing discussions… that’s cool, yet never enough. GIMP needs more people, developers, designers, community people, writers for the website or the documentation, tutorial makers… everyone is welcome in my grand scheme! Many of my actions lately have been towards gathering more people, so when I heard about the GNOME newcomers initiative during GUADEC, I thought that could be a good fit. Thus a few days ago, I had GIMP added in the list of newcomer-friendly GNOME projects, with me as the newcomers mentor. I’ll catch this occasion to remind you all the ways you can contribute to GIMP, and not necessarily as a developer. Read more
