Hosts from LAN1 should be able to access hosts at LAN2 and vice-versa through GRE tunnel between R1 and R2. ISP doesn’t care what networks are behind R1 and R2 so the only way to establish connection between LAN1 and LAN2 is to use VPN, in this example we use GRE.

One of the easiest way to try Chromium browser in Ubuntu Linux (Google Chrome browser for Unix/Linux operating system is named as chromium) is to use daily binary builds at https://launchpad.net/chromium-project.

I was catching up on some feeds yesterday, and this piece of news caught my eye - Amarok 2.1 released. Being a long time Amarok fan ( heck Amarok itself was catalyst to make me use my SUSE 10.0 use full time) - I read the article with great interest. Amarok 2 users would know that Amarok 2 series is a shadow of its old Amarok 1.4(”Amarok Classic” self) - and quite a few people still prefer Amarok classic to Amarok 2 - primararily because of Amarok’s missing support for visualizations, equalizer amongst others. I don’t use equalizers - and as for visualization - well don’t use that either.

I’ve been using Mozilla Thunderbird pretty extensively past few months. Even though I do have Microsoft Outlook installed on my work laptop - with the amount of mails  that I send and receive, Outlook just dies when the Inbox size shoots up and that’s an absolute killer. One of the problems with Thunderbird is that unlike Outlook, its an email-client, and not a complete PIM suite, and my work requires me to maintain an extensive calender system. But thanks to addons, you don’t have to worry about this. Let me show you how you can convert Mozilla Thunderbird to complete PIM suite.

Imagine the following situation: you have to compile some Linux/Unix application or kernel module that requires kernel source present at your hard drive, say, in /usr/src/kernels/kernel-2.6.21-i386/ or elsewhere. But there is not enough disk space to copy these sources or install kernel-devel or linux-source packages (in Fedora/RedHat or Ubuntu/Debian distros respectively)… Sounds familiar? Believe me, sometimes it happens

Well, as for now it is not a problem anymore to open Microsoft Office 2007 .docx documents in any Linux distribution coming with OpenOffice suit. It may be Ubuntu (Feisty, Gutsy, Interpid whatever), almost any version of Fedora/RedHat/Centos, *SUSE, Mandriva and of course Debian (as per my personal opinion it’s the best one).

What is .docx actually? It’s Microsoft’s file format representing word processor documents and named OpenXML (as an attempt to create open and free international standard). Today .docx is default format for Microsoft’s word processor Word.

Well, let’s imagine rather trivial situation: you have Linux router connected to Internet via e.g. ADSL modem and some local network comprising several computers and servers connected to that router via switches and/or Wi-Fi access points.

Done? Ok.

The following is a follow-up to the WPA-PSK HOWTO, describing the way to configure the HP 530 laptop, Slackware 12.1 OS and a Lantech wireless access-point router using WPA2 encryption method. It might be however tuned up to match other router/distro combinations.

This HOWTO describes the way to configure and manage a WPA-PSK (TKIP) connection between a HP 530 laptop running Slackware 12.1 and a Lantech router with a wireless access point. To get the encryption running, the wpa_supplicant package is required. Unfortunately, the stock package didn’t work correctly for me, which I worked around by building it from source, using SlackBuild. (more…)
