Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. “Ubuntu” is an ancient African word, meaning “humanity to others”. The Ubuntu distribution brings the spirit of Ubuntu to the software world.

Our meetings will consist of a group of Linux enthusiast wanting to gain or trade their expertise to talk about the latest news and software releases related to Debian/Ubuntu (Client & Server). Together, we will assist each other in setting up labs for hands-on exercises with migrating to Debian/Ubuntu client software as their primary operating system, to running their own home-based Debian/Ubuntu servers.

To all,
Problem: While trying to perform a spell check in Alpine. I get a(n) “alternate speller terminated abnormally (-1)” message?
Solution: Make sure there is at least one aspell dictionary loaded/installed. Look to see if you have the aspell-en (apt-get install aspell-en) package installed; my bets are that you don’t.

From its outset Ubuntu project has been committed to a regular release cycle and has managed to deliver on that commitment without fail. It is the regularity and reliability of these releases that makes Ubuntu a great option for users and businesses who can plan upgrades and new installs with a reliability that is very unusual in the operating system market. This diagram gives our long term commitment to releases and demonstrates the key difference between a Long Term Support release and our standard releases.
LTS Desktop and Server
Long Term Support releases for desktop and server. There are deployment platforms with wide hardware and software support and ideal or individuals and businesses making a longer term investment in Ubuntu
Standard release
These are the 6 monthly release that contain the best of the new from the Open Source and commercial worlds and suited to users happy to upgrade regularly.
Point Release
These are 6 monthly updates to the long term support cycle. These are primarily bug fixes and patches with occasional feature enhancements that maintain the integrity of the release over a long cycle. The point releases continue up to the next LTS release which then offers an obvious upgrade path for users
LTS Server
This is the extended support period for server.

You can check the current Ethernet network card speed and duplex settings using the following command
sudo ethtool eth0
Where eth0 is the Ethernet network card interface
Turn off Auto-Negotiate feature using the following command
sudo ethtool -s eth0 autoneg off
ethtool Syntax
sudo ethtool -s eth0 speed [SPEED] duplex [DUPLEX]
Example 1
This example will show you how to setup your ethernet network card speed 100 and full duplex
sudo ethtool -s eth0 speed 100 duplex full
Example 2
