Why Linux
  • 1. Free
  • 2. Easy to install as a server or workstation.
  • 3. Great support sites.
  • 4. If using as terminal server cuts down costs on maintenance, upgrades for software and hardware.
  • 5. Educational packages included with installs are similar to costlier applications used with PC and MAC.

How did I get involved with Linux
  • I started using lindows in early 2002.  I was fascinated at how easy it was to install on desktops and laptops.  In 2004 I was introduced to K12LTSP at a summer summit session with Anthony Luscre of Mogadore Schools.  With CD’s in hand I went back to school and installed on some test computers.  I actually caught my tech kids doing their chemistry homework using one of programs.  Etech 2005, Ryan Collins of Kenton Schools introduced me to EDUBUNTU.  I used this to setup up some extra computers that were donated in a special education classroom.  The revolution began.  Teachers wanted more.  I gave the hardware and K12LTSP OS to my tech helpers and told them get this going and I will buy some thin clients for them to build.  In no time they were up and running, so I purchased 6 mini-itx computers from directron.com without HD and CD-Rom.  We tested these in certain elementary classrooms and I showcased them to K-5 teachers.  In a month the principal wanted these to replace the old computers in the K-5 classrooms at the teachers requests.  I was a little hesitant so I found a company called idotpc.com that had cheaper mini-itx systems.   I wanted to use these in case the project went bust I could throw an imaged HD in and not lose any money other than the upgrade cost.  We have not bought the HD’s to date.   A couple of JR High and one freshman really do the setup and upgrades of the servers and clients.  This frees me up for other tasks.

Versions for Education
  •  Fedora was the first Linux OS I used and can be acquired through http://www.k12ltsp.org.  I found this version easy to install but hard to get PC clients to boot from and get the sound to work properly with the thin clients.  An old imac I borrowed booted from it fine.  The support site was very informative to work on a couple of tweaks to get the clients to boot.  It is also a 6 CD or 1 DVD download because it installs all the educational applications.


  • The first time I used EDUBUNTU I found it easiest to use and all my clients loved it except of an old imac I borrowed.  It also has its own very informative support site and is less intensive for downloads. http://www.edubuntu.org.  It is only a 2 CD download with some educational apps on the second CD and the other apps install through an easy to use web interface.

The Server
  • I tested out with 2 old desktops that were AMD Sempron’s with 4 GB of memory and added a gigabit network card.  Since the success of the program I have transitioned to the server below for better speed with applications.
  • HP ProLiant ML115 Opteron 1210 1.8GHz (Dual Core) / 4GB DDR2 ECC PC2-5300 / 160GB SATA HDD / Embedded SATA RAID 0/1/5 Controller / DVD-ROM/CD-RW / Gigabit LAN / 370Watt PSU / Microtower Server.  The only modification was to put in an additional gigabit network card. Cost $580.

The Client
  • The client can be an old computer or laptop with a PXE bootable NIC card.  I had money so I decide to make more room in the classroom. By getting rid of the old bulky desktops.
  • After doing some price quotes I found www.idotpc.com to be a cost effective solution.  An added bonus was they put them together and tested them out.  They also have units with CD-Drive bays.  Remember the client boots through the network card.  No Hard Drive or CD needed.  If you have the money you can put a Hard Drive in and run the OS off that.
