Small Business IT from the ground up
Security is a multi-faceted objective. If you care about protecting your data, you have to protect it from people as well as hardware failure. Thankfully, with Ubuntu you can meet both goals at the same time. This screenshot tutorial will show you exactly how to install Ubuntu Server 12.04 with encrypted LVM on RAID1.
After resolving the “device is not open” error, I got this “SDSocket closed” error. This is how I fixed it.

Information technology is the empowering force behind any modern business. The IT departments of these businesses consist of the technicians that keep this force up and running. But the IT department isn’t always immediately aware of problems as soon as they arise. The rest of the business needs to be able to give performance feedback. And the best method of this feedback is through help desk software.
The 750 typically boots from CD-ROM, hard drive, or PXE boot. But with a quick trip to the BIOS, you can also boot from USB.

Error: No module named solr

Sudo is broken — maybe you need some “sudo crem”?
Permissions and ownership is a perpetual learning process for beginner Linux administrators. There are quite a few things you need to use superuser privileges for in your everyday administration. But let’s say, for instance, you broke your /etc/sudoers file (like I did) and now sudo is broken. What do you do then?
The boss recently tasked me and the other guy with creating a digital document repository to store all of his and his colleagues’ research papers. Of the various options available, Invenio seemed like a good choice, so I built a development site to see if we could get it to work with our system.
One of the most important factors in determining whether this would work for us or not is LDAPS support. Because of the sensitive data that the firm works with, the “S” is very important.
After a couple of hours of sifting through Python scripts, I finally figured out how to add LDAPS to Invenio.
One of the boffins was recently let go. When his MacBook Pro was recovered from him, the other boffins perused the contents to make sure nothing was out of order. It was then my job to save any important data and then wipe the computer. This is what I did and what I learned that I should have done instead to wipe a Mac with a Bootcamp partition. [Read more…]
