Ubuntu Quick Tip: Missing Minimize and Maximize Window Buttons?
Jan 3rd
Hello out there in admin land!
It is I, El Di Pablo here to bring you a quick Ubuntu tip for the week. I haven’t written on aTa in a while due to my hectic schedule, but I am sure you have seen me milling about the comments quite a bit.
Anyhoo, so there I am last night, screwing around on my Ubuntu laptop surfing porn doing homework when I noticed that all of my minimize and maximize buttons were missing from my windows.
The only way to minimize and maximize my windows were to right click on the bottom task bar and select it from the menu. WTF?!?!?
Well, it turns out that those buttons aren’t completely controlled by Gnome. For those buttons, Gnome uses a windows manager call Metacity. To get those buttons back I had to open a terminal and run the following command:
Once I did that, my buttons came back, and I was able to minimize and maximize like a mofo! Do you have any good Ubuntu tips/tricks you want to share? Hit us up in the comments!

Open Source E-Mail Encryption
Dec 21st
“…Perhaps you think your email is legitimate enough that encryption is unwarranted. If you really are a law-abiding citizen with nothing to hide, then why don’t you always send your paper mail on postcards? Why not submit to drug testing on demand? Why require a warrant for police searches of your house? Are you trying to hide something? If you hide your mail inside envelopes, does that mean you must be a subversive or a drug dealer, or maybe a paranoid nut?…” -Philip Zimmerman, Creater of PGP
PGP, or more specifically OpenPGP is a great, and more importantly FREE method of securing your data and your e-mails. You don’t want “The Man” reading your e-mails, and neither do I.
There are many PGP and OpenPGP programs out there, but the one that is the most versatile that I have seen is called GnuPG. It comes in some form for every operating system. It comes standard with Ubuntu Linux, and there are versions for Windows and MAC.
If you are a fan of Mozilla Firefox, and Thunderbird like I am, then you will be happy to know that there are GnuPG plugins for both of them. Enigmail for Thunderbird, and FireGPG for Firefox. Of course you have to have GnuPG installed for the plugins to work.
If you have any doubts on the strength of the encryption, it uses PKI and the encryption keys can go up to 4096 bits, which is so strong that if you take all of the computing power on the planet it would still take something ridiculous like 10 billion years to crack (Give or take). I also found a quaint little article here about how the FBI has problems cracking PGP.
“So ya ya ya, yackity smackity… where do I download this fantastic software?”
I thought you would never ask. You can download it from the following sites:
Enjoy!

Ubuntu Tip of The Week: Changing the Login Message on Ubuntu Server
Dec 15th
Hey boys and girls out in Admin land! I thought I would swing by aTa today to drop a little Ubuntu know-how on ya.
Have you installed Ubuntu server and noticed that when you login to it there is the generic CYA login message from Ubuntu about them not providing warranty blah blah blah blah? Of course you have! Personally, I am not one to stick to defaults very often, especially when it comes to generic welcome messages that can be easily changed! Here is what the original message looks like:
Linux Hostname 2.6.24-18-generic #1 SMP Wed May 28 20:27:26 UTC 2008 i686
The programs included with the Ubuntu system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.
Ubuntu comes with ABSOLUTELY NO WARRANTY, to the extent permitted by
applicable law.
To access official Ubuntu documentation, please visit:
http://help.ubuntu.com/
Yuck! How boring is that? Why not change it to something a little more fun? Or perhaps, if this is a company Ubuntu server, maybe something a little more customized for your company? Changing the message is really quite simple. Just run the following from the terminal:
sudo nano /etc/motd
Make your changes, and save them. It really couldn’t be any easier than that. Now you might have something that looks like this:
For those not in-the-know, motd stands for “Message of The Day” which according to Wikipedia is used to:
…display rules, administrator contact, or simply a piece of ASCII art. This is frequently used in schools or workplaces such as offices.
Have you created a funny or strange motd message on your Linux box? Care to share a screen shot? If you have some good ones, please post a link to them in the comments.
[EDIT]- By The way, if you don’t want your new cool message changed back at reboot, you will also have to edit /etc/motd.tail as well. And yes Jeremy, you can use vi instead of nano!

Confessions of a dude quiting Microsoft Cold Turkey.

Open Source cake… Here is an excerpt that caught my eye that I wanted to share with you:
I have now been Microsoft-Free at work for about 7 weeks. I have also found solutions for almost all of the initial hurdles I encountered in the first week.
Here is the list:
Email – I now have Thunderbird working flawlessly as my email client in sync with Exchange. I do need to talk to the Exchange admin to change a setting on the Exchange Server so I can use the Calendar functionality with Sunbird. I am currently use Webmail for my calendar.
Office – Open Office has worked well with Word, Power Point, Excel, and Adobe documents. I can use Wine to install Visio on my Ubuntu desktop. This doesn’t allow me to be totally Microsoft-Free but there is no answer for Visio’s proprietary format that I am aware of. This is not an issue with Open Source, the problem is that Microsoft doesn’t use an open standard for
their Visio product. Open Office Draw works fine for creating new drawings but can’t import Visio documents saved in Visio format. I also downloaded OxygenOffice Professional that gives me the much needed templates and clip art that Open Office was missing.Browser – I have been using Firefox at work for years so this a no brainer.
Printer – I do have one unresolved issue. I have an old HP Laserjet (about 8 years old). Although I can see the driver I can’t get the printer to work. I have not invested a ton of time trying to fix it.Before all of the Microsoft defenders start slamming me, let me put my disclaimers out.
My goal of this article is to prove that people can be productive at work without the need of Microsoft software. I am not saying that because I can be productive that everyone should abandon Microsoft and start a project to implement Linux corporate wide. However, I do recommend to those who are open to exploring alternatives that they should start a small pilot project with a handful of desktop users. I think a 5-10 person pilot with Ubuntu or Mepis would be a great way to learn about the opportunities and challenges that an Open Source OS resents.
This is low risk and high return.
A pilot like this will give your IT shop an opportunity to try out alternatives without disrupting the day to day business.When I first started my experiment I was trying to keep it a secret out of fear of attacks from angry Microsoft worshipers (especially from the admins and desktop support). What I am finding out is that most of the folks that I was hiding from are sick and tired of supporting Windows and are proponents of Linux. Several of them are using Linux at home. One of the guys I talked to has Vista and XP installed on his laptop. He swaps out the hard drive when switching between OS’s. He is less then impressed with Vista and complains about the slow boot time (2 times slower then XP).
I recently moved to a new office and a desktop guy saw my Ubuntu desktop when I was moving. I expected an ear full but instead the guy said he fully supports a move to Ubuntu and wished the company would move in that direction.
These stories are coming from Microsoft certified engineers who have spent years supporting Microsoft tools. These stories are not coming from anti-Microsoft people who worship Linux.
What to Do With an Older System? Here’s an Idea! (Flashback 1 year ago today!)
Oct 6th
I recently inherited an older computer that really isn’t much good for anything. It is a Toshiba Tecra 8200 with a Pentium III processor and 256MB of RAM. Since it is a little older, and slower than the modern day stuff, I decided I wouldn’t put Windows on it because lets face it, that would just be painful. I decided to put Linux on it because as one of my old bosses once told me,
Since this laptop isn’t much better than an empty soda can, I decided I would give it a shot. I put Xubuntu 7.04 on it because of the lower overhead than regular Ubuntu with Gnome. I couldn’t use the regular Live CD installer though, so I had to use the alternate install cd that uses a text based installer instead. Now everything is working fine.
What I am going to use this for though is something my wife can use when she goes to the coffee shop. She keeps asking if she can borrow my laptop, but I am always using it. Besides, my laptop is running Linux also, which she doesn’t care for so much.
How am I going to make her use this one, when she doesn’t like Linux in the first place? Easy, I am not asking her to completely make the switch (That would be suicide). No, I am only asking her to use this as something to play with when in the coffee shops, or wherever she needs to take a laptop. She still has her desktop PC at home with Windows on it for anything important to her. I also changed the GDM login screen to make it look like a Windows XP welcome screen, and the desktop wallpaper to the grassy fields to make her feel a little more at home! If only I can find a Windows XP USPLASH theme also then this laptop will be complete!

Ubuntu Quick Tip: Installing New True Type Fonts
Sep 30th
Hey boys in girls out in Admin land! It is I, El Di Pablo coming straight at ya from Bauer-Power with some quick Ubuntu knowlege!
I am always playing around with different fonts and such in Windows as I strive to play around in various graphic programs for promotional material and other stuff. Every once in a while I have to add a new font that I downloaded from the Internet. Most of us know how to do that already in Windows (If not, email help_at_asktheadmin_dot_com), but what about Ubuntu?
Ubuntu is starting to gain share in the computer OS realm, and a lot of people want to know how to do average everyday things on it. One of those things people want to know (I know they want to know because they ask me…you know?) is how to add fonts to Ubuntu.
Well its simple, all you have to do is to download your favorite font. Then in your home directory, crate a folder called .fonts (The ‘.’ makes it a hidden file). Just drag your newly downloaded font into that folder and, you guessed it, you are done!
Just open up your favorite graphics program, or whatever else you use fonts in, and your new font will be ready to go!
Got any other Ubuntu tips you want to share with the group? Hit us up in the comments!
