[K12OSN] How to enable USB devices in K12LTSP

Fri Jan 23 16:26:26 UTC 2015

William,
thanks for letting us know.
For those who want an alternative for K12Linux but still want Centos of Fedora, maybe Thinstation is an option?
Greetings, Johan

Hello all,
Barry and I have been communicating extensively off list regarding
install issues with EL7, especially the client build. 

We've pretty much given up. It seems that whatever is left in the
repository is broken with current versions of Fedora and EL 6 or 7. I
know there have been changes in ldm on the server side and have no idea
if that's contributing to the situation. 

Neither of us have the technical chops to begin to figure out what's
broken and how to fix it. Both of us have done K12ltsp/k12linux installs
for years so, while there may be user error, let's just say whatever is
the issue is beyond the reach of more experienced users.

For my use, EL7 has issues also since it's a 64 bit only distro. Clients
or programs which require i686 functionality can be problematic.
Princeton has done an i686 remix (Springdale) if that helps anyone. 

The old repo is still available here:
http://repo.inode0.com/repo/ltsp/
the hawaii mirror is dead

I think this is a problem that has been creeping up on us since ltsp 5.2
began to break things such as hotplug usb.

Alain has found it easier going with Eduntu. I've found Debian quite
easy to get up and going myself. I think the hard part for a lot of us
is that we know our way around Fedora/EL and are loath to figure things
out on a different flavor. 

K12LTSP/K12Linux has been fantastic for us. Moving forward, I think we
have to realize, unless something changes, we all have to move towards a
different solution. LTSP is still as relevant and useful as ever. My
thanks to all who have selflessly contributed time and effort to this.

Regards and best wishes to all,
William Fragakis
