The at command allows you to execute a command or a set of commands at a defined time. It is similar to a cron job except it is used for running the command or task just once.

Having clean URLs for you wordpress website helps your visitors navigate your site easier as well as improve Search Engine Optimization (SEO). In this tutorial we will look at how to set this up on your WordPress site running on an Ubuntu server.

Here is an example. You can see the page URL is /?page_id=4

 

 

In this tutorial we cover how to install and configure WordPress on a Ubuntu server. I will assume you already have Apache, MySQL, PHP (LAMP), and phpMyAdmin running on your Ubuntu machine.

In this tutorial we will look at how to change the hostname of your Ubuntu Linux system. The following steps will work both on the desktop and server platform.

 

How To Check What The Hostname is:

Open up a termnial or ssh into the machine that you want to check. Enter the following command.

Bind9 is used all across the internet for DNS. A survey shows that over 70% of DNS servers on the internet use Bind. In this tutorial we will setup a Bind9 DNS server for your home network with caching.

PhpMyAdmin is a great easy to use web admin interface for your mysql databases. The one down side is it can be a security threat. Seems like many bots on the internet just go looking for phpmyadmin installed on web servers. Then run automated attacks. 

If you have logwatch installed you may often see many failed attemtps.

 

In this tutorial we will have a quick look at the apachtop command. This is great for monitoring your webserver in a terminal or while SSHed into your system. 

 

 

What is ApacheTop:

 

It is defined as a Realtime Apache monitoring tool. It basically watches your log files in realtime and displays the output. This can be real handy for trouble shooting as well as keeping an eye on what files are being accesses at that time.

 

 

In this tutorial we walk through setting up two users with sudo access. The first example we will just add a single user. In the second example we will create a group, configure the group sudo permissions and then add the user to the group. The second method allows us to scale quickly for new users that will need sudo access.

In this tutorial we will cover how to add a new user on ubuntu with the command line. The following commands will work on a desktop system as well as a server. The commands can also be applied on most other Linux distributions as well.

There are many different methods of getting support in todays technical world. Some methods work better for others. I have put together a list of some of the common methods. If you are not fimiliar with what some of these are, please take a look at the bottom of the page for definitions.

When a lot of people come from windows to Linux they often are searching for the My Computer icon or the trash Icon on the desktop. With Ubuntu and many other distributions this is not enabled out of the box. With just a couple quick steps in gconf editor you will be on your way.

You can shutdown or restart your desktop or server with a simple command in bash. It could come in very handy if you ssh into your server or desktop. In this example I a doing it in on Arch Linux with a sudo user. The same commands can be applied in just about any linux distribution such as Ubuntu. You often have to issue the commands as the root user or with sudo in front of the command. (Example: sudo shutdown -r now)

Open up a terminal window

To restart your computer right away type in sudo shutdown -r now

 

The Following Steps can be applied to any Linux Desktop with Bash. This includes Gnome 2, Gnome 3, XFCE, KDE and Unity. This example I am using Ubuntu with the Unity desktop enviorment. If you need help on how to launch a terminal please visit the following links for your desktop.

When power windows users come over to Linux they are often looking for a command similar to ipconfig /all on Linux. Unfortantly I am not aware of a complete replacement one comamnad to occomplish this. You can use the ifconfig command to view your IP address or cat /etc/resulve to view DNS names.

I originally wrote an article on how to map a network drive using Ubuntu. Since then things have really changed in the Linux desktop world. Gnome 3 has been released and Ubuntu has moved away from Gnome and switched to Unity as their primary desktop environment.

The real power of Linux happens at the command line. As time goes on users use the terminal less and less due to the the enhancements on the graphical front ends. There are still many times having some skills with bash commands are very useful.  In this tutorials we will just cover how to launch a terminal in Gnome 2

What is a MAC Address?

 

You can think of a MAC address as a serial number for your network card. It is a unique six two-digits hexadecimal numbers separated by colons. It is used for routing traffic on a network.

 

Note: Changing your default ssh port does not guarantee that you won't get hacked. How ever changing the default really helps cut down on the attempts. Please make sure you have other secure practices in place such as strong passwords.

 

 

With the new desktop enviorment (Unity) in Ubuntu, you now need to take a few extra steps to open a terminal compared to Gnome 2 in the past.

 

Click on the Ubuntu Icon located in the upper left corner.

 

 

In today’s tough economy, companies are always looking for ways to cut cost. One of the first things that gets cut are valuable employees. In the mean time many companies and governments are spending insane amounts of money in maintenance and upgrades of software. Then when the next update comes out they spend that money all over again.

When I redesigned a site that was running on Joomla I had an issue with trying to get my old URLs to point at the new URL. I didn't want the site to lose ranking in the search engine or have any broken links to this site.

Often when you setup multiple websites on a single web server it can be difficult to figure out what database your Joomla site is using. Some times admins get lazy and create poor names or a hosting provider may just give you a random generated database name. In this tutorial we will look at four different methods on how to find the database name of your Joomla site.

If you are looking for information on what is the mysql database username and password are set to, use the "Find Your Joomla Database Name and Login Information with SSH:" steps below.

(Note: Joomla 1.7 was used in the following examples. The same steps should apply to other versions as well.)

 

 

Google Chrome Browser can be installed on just about any Operating System such as Linux, Mac or Windows.  It has a lot of great features built in out of the box. These are just a few of my favorite that most people don't know about.

   

Overview:

 

"Ubuntu" is an ancient African word, meaning "humanity to others".

Ubuntu is a Linux operating system originally based on the Debian GNU/Linux distribution and distributed as free and open source software.

Some newer Linux users may not be aware that many Linux distributions use workspaces. It can be a bit frustrating if you accidentally bump something and switch to another workspace. So instead of trying to avoid them, lets look at some fancy ways you can switch between them.

Workspaces can be a real nice feature and helps keep you organized while you work. In this article I am using Ubuntu and using the default keyboard shortcuts. The 3D desktop cube will require you to install Advanced Desktop Effects Settings (CCSM) – CompizConfig Settings Manager, and enable the 3D cube. This can be installed using Ubuntu Software Center.

In this example I am switching between workspaces using the keyboard shortcut Windows Key + E
