There was a separate DVD release, but it has gotten rather stale. The best way to install it is to follow the instructions on the wiki. https://fedorahosted.org/k12linux/ As a rule, this is the place to check for answers first. If it's not included there, then ask on this list. That way we can add FAQs to the wiki! > 3. Is there fat clients support?

Naturally, to run apps on the fat clients you need clients powerful enough to do this, but otherwise it should work fine. You simply need to enable local apps, install the app in the thin client chroot, and then create a shortcut that uses the local app. > Thanks for any respond :) > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org iEYEARECAAYFAlDINcMACgkQxWV7OPa/g5EjQgCeLphAvjqN76gs253u5BGX3TKx xPoAn2yZvr0bmu1Z+CbgLZ2pNyJrNqNY =FW1A -----END PGP SIGNATURE----- From william at fragakis.com Wed Dec 12 17:33:21 2012 From: william at fragakis.com (William Fragakis) Date: Wed, 12 Dec 2012 12:33:21 -0500 Subject: [K12OSN] Welcome!

With Wireshark open and not doing any actual 'capturing', when I click on the far left icon on the toolbar of Wireshark,which shows you the available interface capture devices. You can see the packets going in & out of each interface. When looking at ltspbr0 & eth0 ( which are the bridged interfaces),,,the ltspbr0 interface shows several less incoming and outgoing packets,,,in just a short amount of time. As dumb as I am I would naturally think the two bridged interfaces should be showing identical packet count. Has anyone else on board here ever seen this,,or maybe have never stumbled across this ? I never really calculated in a percentage,but I can not help but think,this is hampering network throughput to some degree or another. I do not want to spend a bunch of time,,trying to over anaylize this but just was curious if anyone else may be seeing the same behaviour?

There's a difference there. I tried googling this, but haven't found out exactly what that is or does though. I could see forcing a certain queue size adding packets to what eventually gets sent, if there is also some minimum time interval to flushing the queue or something.
