Ubuntu 10.04 rescue information

by on January 12, 2013 at 9:35 pm

I recently encountered a problematic server running Ubuntu 10.04 server.  The problem was simple, and so was the solution, but there were many hurdles in the way that, if you’re not familiar with them, will prevent you from accomplishing the task.  This should apply to later Ubuntu distros as well.

Scenario:  The server is a Dell, on the other side of the country.  You have only DRAC access, no ability to manipulate anything physically.  Somehow, the root password was changed, and now no one can log into the server remotely. (more…)

Debian Wheezy PXE server

Creating a PXE boot server is both easy and useful.  PXE boot services allow an administrator to install or boot an operating system dynamically every time a machine is booted.  This method is especially useful for imaging multiple servers in an automated fashion.

I’m writing this entry to outline the steps necessary to create a Debian server that provides DHCP and PXE boot services of multiple to specific hosts on the same network.

Requirements:  Debian Wheezy or other compatible server with plenty of free space, and an additional server/computer on the same network (or virtual network) as the Debian server.  If you’re using something other than Debian Wheezy, I can’t assure you the packages will be the same and configured the same way.  This is Linux, after all.

Fedora 18 Beta Screen Shots and Review

Fedora 18 beta has finally been released, after much delay.  If you’re a follower of the Red Hat world, then you know Fedora 18 is likely going to serve as part of the upstream base for Red Hat Enterprise Linux 7, which is reportedly supposed to be released in beta form sometime next year.  Also, I feel Fedora is now really offering a great user experience and deserves to be explored as a primary desktop distro.

Juniper Network Connect Linux Mint Debian 64bit

I spent the better part of 1-2 hours trying to install Juniper Network Connect SSL VPN software on my machine.  Reason being is that JNC doesn’t natively support x86_64 Java or libraries.  Much of the info online is either out-dated, requires you to run someone’s lengthy hand-written script (no thanks), or just plain wrong.

Here’s everything you need to get JNC running on Linux Mint Debian Edition.  This install assumes a cleanly installed system with packages up to date, and will likely run on similar systems (Debian, Ubuntu, etc).  I’m running Xfce as my desktop, but it should work for all major desktops.

Debian 7 Wheezy testing

1
by on September 7, 2012 at 9:58 pm

Well, I had been putting it off for some time, but I finally installed Debian testing, aka “Wheezy.”

There are rumors on the internet about this shipping with Xfce to fit on a single CD, however I downloaded and installed the latest weekly build, and it indeed came with Gnome 3.  In my case, I installed the OS into Virtual Box.  Gnome 3 failed to launch, and I only had the fail safe mode.  On Fedora 17, I get the full Gnome 3 desktop with the same settings in Virtual Box, which leads me to believe Fedora might be using a newer package or better VM video drivers.

I think Gnome 3 is a step in the wrong direction for Linux, and I’ll be majorly happy if Debian indeed switches to Xfce for desktop use.

As far as the installation of the OS goes, it’s pretty straight forward, much the same as Squeeze.  A few minor changes, and a very ugly pink loading bar.  It’s not ugly strictly because it’s pink, just that it doesn’t fit with the other colors of the screen.  I know this is fickle, but just my opinion ;)

 

Anyway, if you actually read this and found it helpful, I’m glad :)

Debian and Ubuntu: Enable Java in Google Chrome

Debian Chrome Linux Logo

I’m writing this article for primarily for Debian Squeeze users, but it should also apply for Ubuntu 12.04 LTS and other releases as well, as the steps will be pretty much the same.

After you have downloaded and installed Google Chrome, you’ll most likely want to get Java working as well.  Follow this article, and you’ll be up and running in no time.

Top 5 Reasons to use the vi/vim editor

1
by on July 12, 2012 at 4:24 pm

It is debatable as to what the ‘best’ editor is in Unix/Linux world.  I’m not going to attempt to answer that here, as it’s very subjective and besides the point.  What I will do is outline the top 5 reasons that you should use vi, or at least familiarize yourself with it’s commands and basic usage.

1:

It’s free!

2:

Commands are quick and intuitive.  After you’ve acquainted yourself with the commands, the built in functionality covers just about any task you can complete with a mouse.

3:

Color syntax highlighting.  If your terminal supports color, integrated syntax highlighting makes reading and editing scripts a much easier proposition.

4:

You never have to leave your terminal.  Most servers and production systems are located in a cold room with funny lighting, somewhere far away.  If you’re working from a non-free operating system (GASP!), there’s nothing more annoying than having to upload the same file several times while you’re trying to tweak a setting.  If you posses vi skills, you’ve already made your changes, saved the new file, and restarted your application, all before your mouse can even find the locally saved file!

5:

It’s a ubiquitous application.  It’s available on just about any *nix machine you’re likely to find in production today.  If you work on or in a mixed OS environment, then you know it’s not very often your tools are so portable.  Learn vi, and you’re covered for just about any appliance you can ssh into!

Install Magento in Debian Linux

Magento is a freely available shopping cart / ecommerce solution in production use all over the internet.  In this article, I’ll be outlining the steps to install Magento Community edition in Debian Squeeze.  It’s really quite simple if you’re using Apache2.  While NginX is supported by the latest release of Magento, the steps to install using NginX won’t be outlined here, but may be in another article in the future!

Debian Squeeze: Installing Google Chrome

If you’re running Debian Squeeze or a related distro as your primary desktop system, you will more than likely want to browse the web at some point.

If you elected the graphic install option, and enabled the GUI by default, you should be armed with a few web browsers:  Iceweasel and Epiphany.  While these are excellent browsers in the open source community, Google Chrome also enjoys great support in the Linux realm.  These instructions should work just about the same for any Debian-based distro, such as Ubuntu and Linux Mint.

Configuring CentOS 6 Web Server

Centos 6 in 3DIn this article, I’m going to be outlining the steps to install and configure a complete web server on a base install of CentOS 6.  (Which should be compatible with Scientific Linux 6 as well as Red Hat Enterprise Linux 6)

I personally don’t prefer to install package groups relating to “LAMP” or similar during initial installation because I’m simply too lazy to review each and every package that is included in those groups, and what the dependencies are. By installing the required packages using yum, this allows you to install just the software you’re looking for, without worrying about dependencies. This software stack is time tested; we’ll install on CentOS’s latest release, and test a few popular applications while we’re at it!
