Dear Terrell,

thanks for the advice! I installed K12LTSP 5.0EL. Some how the kernel
source is installed by default, because I haven't seen any distinctive
selection during the setup. Compiling the drivers for a Attansic L2
works fine.

I added a 2nd network card to the server, a 3com 3C905B-TX. K12LTSP
5.0EL didn't recognize this card by default. I downloaded and compile
the driver. still not recognized. About to change the network card, I
first changed the PCI slot on the board. And the network card is

Does a driver for the 3com 3C905B-TX come in the K12LTSP 5.0EL
distribution or is the downloaded / compiled driver working now?

Both NICs are working fine. One for the Internet access, one for the
thin client net. Everything automatic setup by default. Nice!

Hello Leo,

The K12LTSP is indeed a great system for computer labs.  It also works
very well in a business situation.  You made a good choice.

One thing before we get started:  you should plan ASAP to "upgrade" to
K12LTSP 5.0EL, as Fedora Core 6 (the basis of K12LTSP 6.0.0) hasn't
received security updates since December 2007.  You are thus vulnerable
to getting hacked.  CentOS 5, the basis of K12LTSP 5.0EL, on the other
hand, will be supported to the year 2014.  Turns out that CentOS 5 looks
and acts virtually identical to Fedora Core 6, so your users won't
experience user-interface disruption.

There are two ways to install what you're after.  There's the command
line way, and there's the GUI way.  To install the kernel source on my
system (K12LTSP 4.2EL) from the command line, I did this, as root:

 yum install kernel-devel

which should also install the header files.  The GUI way is to fire up
the "Add/Remove Programs" application and install the "kernel-devel"

Do you GNU <http://www.gnu.org>?
Microsoft Free since 2003 <http://www.cmosnetworks.com>--the ultimate
antivirus protection!
