How to install Guest Additions in Ubuntu 14.04 Server for VirtualBox

VirtualBox

This is a very short blurb on how to install guest additions in ubuntu 14.04 server for Virtualbox.  This is very simple to do yet I never remember.  I also use Virtualbox a lot but that doesn’t seem to help me remember.  Very simply, if you are using Ubuntu server this is the command to enter in terminal:

sudo apt-get install virtualbox-guest-dkms 

What is Chromixium?

What is Chromixium?  Chromixium is an attempt to make linux appear and act just like Google’s Chrome OS.  Google doesn’t release Chrome OS as a stand alone operating system and I needed to give an old computer to someone to use.  If the person isn’t very tech savvy I am always hesitant to keep Windows on it.  The amount of time wasted on infected windows machines is maddening.

Chromixium is really Ubuntu with a different skin.  I had an old Vista notebook lying around collecting dust.  It’s actually been collecting dust for a few years.  The problem with it was it just didn’t stay on.  It shut itself off randomly.  From what I could tell it was because of heat issues.  I installed ChromeOS without a hitch and let it run for 24 hours and not a single issue!  I’m very happy with this.

I had first attempted to install it on an even older laptop.  A Dell Latitude 600m that had Windows XP.  It has a Pentium M chip that required me to run a special command called “Force PAE” but on the subsequent reboot after the install the hard drive appeared to be on it’s last legs.  The hard drive is so old in it I didn’t have a compatible hard drive to replace it.  I decided to shelve that computer and decided to try my luck with my old Lenovo with Windows Vista.

While I only played with the computer for a very short time I didn’t run into any issues.  Things worked “differently” than chrome os.  One, I was using chromium instead of chrome and two, things like google drive just opened as a new window instead of as an app.  Not a big deal to me.

If a person has time they should check it out.

Fixed SNMP Security Flaw using a Print Server

I kept receiving a highly critical security message about SNMP on the security reports.  Been seeing it for a long time but I couldn’t figure out how to solve it.  It seems like Windows 7 would not print unless SMNP was enabled.  No matter what setting I changed it wouldn’t print.

I read about setting up a print server.  I had set one up before but never used it.  What I did was I enabled CUPS in the Ubuntu 12.04 server and setup the print server using CUPS.  My problem in the past seems to have been that I didn’t know how to use the print server.  I found these great instructions and it seems so simple now.

Basically you have to add the printer that is located on the print server.  You added by the IP address.  For example it could be \\192.168.1.100\konica if “konica” is the name of the print queue and “192.168.1.100” is the print server IP address.

With that all fixed I now have no SNMP issues!

Very Small Text using Nvidia Drivers in Lubuntu 14.04

I have very small text using nvidia drivers in my new Lubuntu 14.04 install. So small in fact that I couldn’t read anything!

I found an old thread from 2012 that helped point me in the right direction.

Click on Menu then Preferences and then “Customize Look and Feel”

Under the widget tab I changed the default font to a size of 24. After clicking apply it fixed the text in the windows but not the icon text.

I then clicked the font tab and changed the sub-pixel geometry from RGB to BGR. After saving it I have a nice looking screen again.

The problem is I haven’t figured out to keep the saved settings!

Here is that original thread that seemed to be the same issue yet no one was able to give an answer.

OPENVPN on Ubuntu 12.04

I run into plenty of instances where the instructions to install openvpn are wrong. They aren’t necessarily wrong but they are missing important steps. I’m not sure why this is happening but I have wasted hours trying to figure these issues out.

Looking at one set of instructions I realize that I need to edit the server.conf file, yet I don’t have a server.conf file! I believe there is a sample server.conf file to use but now I must use Google to figure out where the sample files are.

In this instance my answer is located in the official openvpn instructions.

the sample-config-files directory in /usr/share/doc/packages/openvpn or /usr/share/doc/openvpn-2.0 if you installed from an RPM package.

The next problem I ran into is why I am getting errors when I type Source Vars. In this instance I need to rename the openssl-1.0.0.conf to openssl.conf. Again, I found1 spot where it mentioned to do this.
