I have three thin clients that are my own personal TC's for sale. (2) Ebox 2300's with power adapter $35 ea (1) HP T5530 $35 ,,All are fanless and vesa mountable. + shipping The two Ebox's work fine on ltsp 4.x .Will NOT work on ltsp 5.x. The HP T5530 works fine in ltsp 5.x other than some flash sites and any RED5 hosted website it bogs down.On most websites is very snappy and will run all Youtubes' Openoffice ,Libreoffice ,fine for example.

I am just trying to get a better understanding in regards to some voip problems I am experiencing since putting this server online. Notes 1) This server has the integrated Realtek RTL8111e nic.(rev 06) 2) The second nic pci-e is also an RTL81111e (rev 02) 3) The integrated nic (external nic) will only negotiate at 100mb. If I try and force via ethtool to 1000MB my net connection simply stops. 4) The two nics both use the native r8169 driver with the onboard nic also showing a firmware as well and the pci-e nic does not show a firmware being used? 5) On my Vonage phone now my voice quality is usable but is very speradic,,for the listener. This never happened with my old server. The Vonage phone does run 'behind' my LTSP server. 6) The mobo manufactuer does not show a firmware update for the onboard nic. For some reason I think this is my voip problem as I have read many older posts were users with Windows reported frequent network drops using the Windows supplied driver for this embedded nic. I know I should have gotten a mobo more Intel centric,,,:) The below iperf capture is via a vpn connection so there is some overhead involved here,but seeing how many 'dropped' readings there are I assume I definaetly have a problem somewhere along the line. I connected to three different servers at work,to try and get an average.All results were very close to being the same. #iperf run print out# iperf -c 172.28.8.66 -i 1 -t 60 ------------------------------------------------------------ Client connecting to 172.28.8.66, TCP port 5001 TCP window size: 21.6 KByte (default) ------------------------------------------------------------ [ 3] local 172.31.100.254 port 37457 connected with 172.28.8.66 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 1.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 1.0- 2.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 2.0- 3.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 3.0- 4.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 4.0- 5.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 5.0- 6.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 6.0- 7.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 7.0- 8.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 8.0- 9.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 9.0-10.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 10.0-11.0 sec 256 KBytes 2.10 Mbits/sec [ 3] 11.0-12.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 12.0-13.0 sec 256 KBytes 2.10 Mbits/sec [ 3] 13.0-14.0 sec 1.00 MBytes 8.39 Mbits/sec [ 3] 14.0-15.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 15.0-16.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 16.0-17.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 17.0-18.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 18.0-19.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 19.0-20.0 sec 256 KBytes 2.10 Mbits/sec [ 3] 20.0-21.0 sec 1.12 MBytes 9.44 Mbits/sec [ 3] 21.0-22.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 22.0-23.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 23.0-24.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 24.0-25.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 25.0-26.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 26.0-27.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 27.0-28.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 28.0-29.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 29.0-30.0 sec 384 KBytes 3.15 Mbits/sec [ 3] 30.0-31.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 31.0-32.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 32.0-33.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 33.0-34.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 34.0-35.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 35.0-36.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 36.0-37.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 37.0-38.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 38.0-39.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 39.0-40.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 40.0-41.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 41.0-42.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 42.0-43.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 43.0-44.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 44.0-45.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 45.0-46.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 46.0-47.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 47.0-48.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 48.0-49.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 49.0-50.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 50.0-51.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 51.0-52.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 52.0-53.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 53.0-54.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 54.0-55.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 55.0-56.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 56.0-57.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 57.0-58.0 sec 0.00 Bytes 0.00 bits/sec [ 3] 58.0-59.0 sec 640 KBytes 5.24 Mbits/sec [ 3] 59.0-60.0 sec 512 KBytes 4.19 Mbits/sec [ 3] 0.0-60.7 sec 26.1 MBytes 3.61 Mbits/sec Thank You, Barry From cisna-barry at wc235.k12.il.us Tue Nov 13 21:52:31 2012 From: cisna-barry at wc235.k12.il.us (Barry R Cisna) Date: Tue, 13 Nov 2012 15:52:31 -0600 Subject: [K12OSN] traffic shaping - QoS Message-ID: <1352843551.13983.24.camel@server1.eazylivin.net> Hello All, Note: This is for sure not k12ltsp/k12linux specific, but thought someone might get some good from this. I just wanted to share with whoever here a neat find for doing traffic shaping with the built-in tc_htb in the Linux kernel. On the new home server , CentOS 6.3 32-bit / k12ltsp 5.0 I built recently I was really struggling with getting the asterisk,piece along with a Vonage phone that I have had for 6 years now,,to function correctly, without cutouts,etc. Of course voip is about as touchy/moody as you can get in regards to packet passing etc. There is such a miriad of approaches to doing traffic shaping/ QoS with the tc_htb piece and it seemed each writeup/documentation defied the next one I read. I wound up diving into the following approach and for the last 4 days both my asterisk phone(s) and my Vonage phone are rock solid. Once I done many reads on this i finally was able to get my head around how this all ties together. The key for me was to use the webmin-htb module which is a module that goes into Webmin. Without having a good graphical 'look' at all this I prolly would have thrown in the towel. Here is the link for anyone interested. http://sehier.fr/webmin-htb/ Take Care, Barry From radek at bursztynowski.waw.pl Wed Nov 14 19:32:20 2012 From: radek at bursztynowski.waw.pl (Radek Bursztynowski) Date: Wed, 14 Nov 2012 20:32:20 +0100 Subject: [K12OSN] freerdep problem Message-ID: <1352921541.3353.28.camel@alpaga.bursztynowski.waw.pl> Hello, I am new one on this list.

It is true - in /opt/ltsp/i386/usr/bin there is no xfreerdp. I installed rdesktop package (chroot /opt/ltsp/i386 yum install rdesktop) and my problem is solved. I'am suprised that xfreerdp or rdesktop package is not joined to K12Linux. Unbuntu enclose it. My rdesktop package instaltaion is done in i386 environement (CentOS 6.3 i386). Now I am going to check what will chappened with x86_64 environemet. My server is CentOS 6.3 x86_64 and using chroot I installed Fedora 14 (i686), Fedora 11 (i586) and Scientific Linux (i686) LTSP clients. My question is: what will happened with rdesktop or xfreerdp when I will make: chroot opt/ltsp/i386-fed11 yum install rdesktop in x86_64 environmet, and next: chroot opt/ltsp/i386-fed14 yum install rdesktop, and next chroot opt/ltsp/i386-sl63 yum install rdesktop?

This happened to me when I restored a client image backup, but because my backup script excludes /proc it was missing altogether in the restored image. Unfortunately this causes dracut to throw up the significantly incorrect "no root device found" message, even if the root filesystem is successfully mounted.

About two weeks ago i decided to setup firefox to run via localapps for the first time ever using ltsp/k12linux just to see how things works out using Firefox in this fashion. Using an p4 with 2GB of ram on client. Gig-E Lan. This is the only client I have tested Firefox on. I installed Firefox, flash-plugin, icedtea-web only. Firefox does open very quickly on the client but Firefox does quite frequently crashes and goes shut. Has anyone else experienced this behaviour?

There is no possiblity to install rdesktop or xfreerdp packages using chroot to /opt/ltsp/i386 directory because there is confilict of packages (/opt/ltsp/i386 directory holds i686 packages, bud main server is x86_64).

This prevents flash heavy pages from loading down the server and clients, but still allowing you to use flash where you need it on your clients. So often it's all the ads that use flash in the background or are running some kind of flash tracking cookies.

I will give this a try. This happens on any one client using Google Chrome in that anything in flash with sound the video runs fine but the sound cuts in/out repeatedly. Youtube is an example of this behavior. I am going to try and set up Chrome to run as a local app and see if the problem is lessened or worsened. Also worth mentioning is in a matter of time Chrome will eventually stop 'drawing'. In other words it does not hard lock, but the browser itself shows some content correctly but most of the page is all gray for example. As a side note I have tested the system memory with memtest86 and looks OK. This server I built is pretty marginal CPU for home use and is an AMD processor and from doing some Googling there seems to be somewhat of an pattern with flash being problematic with AMD processor driven machines? It is a lowly E350 Zotac Fusion APU with 8gb ram. I built this with the intent of doing a 'power saving/go green' approach and then using three TCs of 1gig cpu 1 gig ram 1 gig lan at each of the three seats and running all local apps on each of the TCs. I am guessing this APU simply does not have enough umph to produce reliable video/audio. Looking back i experience this same thing on many of the laptops at school were there sound 'struggles' on pretty much the same mainboard architercture. For some reason running Firefox as an local app on the TC's is crashing frequently when opening just a couple flash sites to thrash Firefox even a little. >From what I have been able to read up on,Chrome has a native flash built in but you can override this by disabling it and enabling the system flash-plugin (which does show up in the Chrome plug-ins).
