When you connect to the local console of the client and tail /var/log/messages you should see something about a USB device being disconnected/reconnected? If you do then it is being "seen". After that you need to make sure the chroot kernel and all supporting packages required by the reader are present _on the chroot_. > In lts.conf I have added localapps=True, the user is added to fuse > group, so he can use usb's. I assume you added the user to the fuse group on the server? If so then this won't affect the client directly but it's not likely an issue either way. Keep in mind that with respect to the USB id reader nothing configured on the server matters, only the chroot. Jeff T Hello Jef, thanks for the reaction. The user is added to the chroot. I mean the card reader is not mounted under /media as a usb-device would. I don't know how to connect to the local console of the client. I have two types of thinclients, one Hp device with a hard drive and Linux on it, one being just a motherboard, no hard drive.

If the client does mount it check in /media// on the server but I suspect the client isn't mounting it at all. It is certainly picky about what it mounts with fuse. For example I never could get it to mount anything in a USB DVD drive. > I don't know how to connect to the local console of the client. You can try running ltsp-localapps xterm from the server.

If all devices need dedicated gigabit connectivity, then you can add a second NIC to the server and either a. expand nfs/dhcp/tftp ranges (complicated) or b. bond the NICs (less complicated) and add a second gigabit switch for future expansion. For network hygiene, I'd ponder re-purposing a box, installing pfsense, and letting it become your firewall/gateway/dansguardian/squidguard box. --scott -------------- next part -------------- An HTML attachment was scrubbed...

Given the poor fiscal support of schools in general, LTSP (and a next gen thing I'm still poking at) are the most cost effective ways to put students in front of computers for any reason. Next Gen Thing: server(s) runs Ovirt and many generic VMs. Student uses wireless android pad/laptop and connects using spice to get full desktop with sound and video. Memory usage is similar using memory ballooning (shared, read-only memory) as all VMs are identical. Drive space is similar (only /home is different for each) and it works over wireless and from home. Big advantage is 3-fold A) GUI for admin of VM environment (and user authentication using freeIPA has gui as well) B) better stability and security - student can only crash their VM, not the classroom or half the school. C) can use BYOD (mostly) as there is a spice client for windows, Linux, Mac and Android. I've found cheap android laptops for $100. tiny screen and keyboard but good size for little hands. Can still use this stuff for stand-alone machine lab setup by mounting /home from nfsv4 server. Good for video work. Most stuff needs minimal horsepower. Bigger kids can get bigger android laptops for $170. If schools could figure out how to use freetextbooks, the backpack load for the kids drops to 3-5 lbs. down from 20-40 lbs. Flash is still a hog. Wish it would go the way of the dodo bird. Wouldn't is be cool for kids to be able to say they use a supercomputer every day at school? !!!

Wanted to share for anyone else that may run into same problem after updating (server) to CentOS 6.5 with the flash-plugin crashing on a remote x display. The fix for any version of flash-plugin crashing on CentOS 6.5 and Firefox 24 was to install the HTML5 extension into Firefox. I done this step just to see if Youtubes would in fact run in the 'native HTML5 format' as this is what Youtube is eventually suppose to go to exclusively. After installing the HTML5 extension into Firefox,this not only fixed Youtubes/ "flashplayer has crashed" error,from crashing but all other flash background features in all websites I have tried. Don't have a clue what went on under the hood and don't care at this point. :) For some reason I think the culprit is actually the new xulrunner that is installed along side of Firefox 24,but not sure of that.

The cure in our case was to make sure that we had hardware acceleration disabled. If necessary, we'd have to log in on the server, load firefox/flash and make the change since flash would bomb almost immediately on a client. Thanks for the alternative work around.

This is my first post here. I have enjoyed reading (and learning) all the other posts. Great information. I have a centos 6.3 and k12 ltsp environment. I currently have thin clients that are old (almost 10 years) and are in need of replacement. Parts are breaking due to age and are harder to come by. I have been getting parts on amazon and other sites. However I wanted to hear what kind of hardware are you using for your thin clients. WYSE HP Self-configured thin clients. Thank you.

Self configured for me. I could never find any off the shelf clients that had everything I wanted at a reasonable price. By far my favorite all-around client has been the D945GSEJT with Morex T1610 case: http://www.silentpcreview.com/Intel_D945GSEJT_with_Morex_T1610 Thin, fanless, easy to assemble, reliable, well supported. The only thing wrong with them is the GPU which really can't do anything accelerated. For boxes where I needed proper 3D support I went with a Zotac IONITX board. Sadly the D945GSEJT is now EOS and the Intel replacements I last looked into (granted a while ago) all had issues with Linux GPU drivers. Something like this may still be a viable option though: http://www.newegg.com/Product/Product.aspx?Item=N82E16856173032 However, it lacks the fanless aspect and is significantly more power hungry.

These are primarily the t5730/35 and t5740/45 with Sempron and Atom processors respectively. The 5740 doesn't play well with EL 6.4 and earlier so you may need to create a boot image like we did from Debian. A number of these units have embedded WinXP so as XP sunsets this year, you may see more of them appearing. If you buy lots on ebay, you can get them from anywhere from $25-60 per unit shipped. Just make sure they include power supplies. The 574x run more because of the Atom cpu but both models tend to come with 1-2gb RAM often with stands and even keyboards and mice. The 573x are also a touch larger. Refurb desktops aren't much more and readily available, too, but use more space and power.
