Shortcut to root command line access while logged in as un-privileged user

August 31, 2009

Let’s say you’re logged into your Ubuntu machine as an unprivileged user, meaning that you don’t have permission to use the sudo command on the command line. As such, you cannot update the system, install a program, or perform other tasks in the terminal that require the sudo command without logging out and then back in as the administrative user, or using the User Switcher. This annoys me. So, how do I execute commands in the terminal that require the sudo command while still logged in as the unprivileged user??

First off, you’ll need ssh. To make sure you have this installed, login to your administrative account (a step that will soon become unnecessary), open a terminal, and enter…

sudo apt-get install openssh-server openssh-client

After this install is finished you can logout, and back in as the unprivileged user.Now you can open a terminal and enter…

ssh [administrative username]@127.0.0.1

You’ll be asked for your password, this is the administrative account’s password, enter it and press enter. Now, you’ll have a command line prompt for the administrative user, as if you had logged in as that user and opened a terminal. You can now update the system, or make whatever change you need to make that requires you to enter your sudo password.

A nice time saving trick.


How to find out which version / release of Ubuntu you have

August 26, 2009

Have you ever asked yourself, “How do I find out exactly which version, or release, of Ubunut I have?” There are a few ways of doing this.

The easiest, and most basic, is to open the System Monitor.You do this by going to System > Administration > System Monitor. You then click on the System tab. There you’ll see which version of Ubuntu you’re using, along with your linux kernel, and which version of gnome you have. However, this information can be incomplete. For example, if I do this, I’m told that I have Ubuntu 8.04. Well, I do, but there’s more to it than that.

See, Ubuntu has what’s called point releases for the long term support versions of Ubuntu, which 8.04 is. Check their website here, for an explanation. So, knowing that I have Ubuntu 8.04 does not tell me which point release I have. What can I do if I want that information?? Well, that’s pretty easy too.

I have to open up a terminal. To do that I go into the Accessories menu, and choose Terminal. Then I enter this…

cat /etc/issue.net

And when I do that, I’m told that I have Ubuntu 8.04.3 LTS. This let’s me know that I am using the third point release. This is what I wanted to find out.

Any other ways of doing this that you prefer???


Shuttleworth’s thoughts on Windows 7

January 23, 2009

You’ve heard of Microsoft’s new operating system, Windows 7. Mark Shuttleworth, founder of Ubuntu, shared his thoughts on the new version of Windows with the UK’s Register.

Here’s an excerpt…

“I’ve kicked the tires on the [Windows 7] beta for a few hours and it was good,” Shuttleworth said. “They’ve put concerted attention on the user experience with the shell.

Should you upgrade to each new release of Ubuntu?? Why ?? Why not??

December 17, 2008

A new version of Ubuntu is released every 6 months, and it’s very easy to upgrade. All you have to do is click a button or two in your update manager and there you have it. You’ve just gone from Ubuntu 8.04 to Ubuntu 8.10! Is this something that you should be doing?? You could upgrade every six months, or you could upgrade every 2 years. Which would you prefer?? I’ve chosen to upgrade every 2 years. Here’s why…

How to lock your screen from the command line

December 11, 2008

This could be very useful to you if you’re working in the terminal and need to step away for a moment. You can achieve a locked screen, just like when you do it the graphical way, with this command entered at the command line, or cli…

gnome-screensaver-command –lock

NOTE –In this command, where you see “–lock”, it is really 2 hyphens with no spaces in between, followed by “lock” …  – – lock. WordPress renders two hyphens put together as… –

This will instantly launch your screensaver, and lock your computer’s screen. Your password will be required to gain access to your system once this is activated.

That command is pretty long, and typing it out would probably get on my nerves. You can use an alias to effectively shorten it. Here’s how we’ll do that, also at the command line…

Let’s say we want to be able to type in lock, to lock the screen. If I just type in lock, I get nothing. So I need to create an alias for this command. An alias is just like what it sounds like. It’s assigning another name to a certain command. At the command line enter…
