Via, AMD, and Intel all make them nowadays. They're not quite $50, but they're not horrendously expensive, either.

I tried two different TC's that were being fed by two different servers,and this simple animation rendered the TC's almost useless. They were so sluggish that menu displays in Firefox were delayed by almost 60 seconds. Once I navigated to another web page then the sluggishness disappeared. It just seems very odd that something that this simple can take down each TC's performance. I m not smart enough to decypher what actually degrades the processing so much? Just thinking out loud.

Greetings, I've seen over the past few months that Google has gotten quite a bit slower to load on every system. The "bucky ball" on 9/4 rendered my ancient Toshiba laptop unusable. I don't think it was Flash, however. My Toshiba doesn't have a flash player installed. This may have been rendered using Javascript. Frankly, I gave up on trying to decipher the source code for the Google home page. The lack of consideration for lower speed devices by web designers is very frustrating. It is not simply thin clients that get hosed, it is every sub-1ghz processor that is hammered. Where, oh where, are the W3C compliant web sites? -- jeff williams - cfiaime at cfiaime.com From mpelletier at tcz.co.zw Sat Sep 4 17:46:25 2010 From: mpelletier at tcz.co.zw (Mathieu Pelletier) Date: Sat, 04 Sep 2010 19:46:25 +0200 Subject: [K12OSN] ltsp on MIPS and ARM architecture References: Message-ID: <4C8285F1.5010902@tcz.co.zw> Hello Terrell, Thanks for the suggestion regarding Atom or other ULV processors, but I think this is the easy way out and circumvents what could be a very meaningful development in LTSP. We can get about 3-4 arm or mips thin clients for the price of one atom based client. Moreover, I am trying to do this as way to redress the apparent technology gap here in the developing world. It should be pretty easy to build a thin client image for ARM (particularly as linux already runs on ARM). I understand that MIPS has some support, but it is not as good as ARM. Anyway, I was actually hoping to find if anyone knew if there was work under way to get LTSP working on these architectures. Does anyone else have any ideas? I suppose I could start by compiling my own, but I would like to see this make it into the standard development chain. ~Regards, Mathieu Pelletier Biblical Studies Department Theological College of Zimbabwe Tel: +263 9 287032/3 Ext: 214 mpelletier at tcz.co.zw www.tczonline.com Chat Google Talk: mkpelletier Skype: mathieu.pelletier -------------- next part -------------- An HTML attachment was scrubbed...

I believe in this case it is java,,somehow,embedded image. If I right click the spinning whatever it is, I do not get the "about" and other flash preferences,flash thingy. I also have noticed in the last few months that Google,,,,menus 'fade in",,and since this time,,it does take the Google main page to load on any given system noticebly longer.

OK. The animation is gone on Google's site today 9/5. This is one of their one day,,logo alterations they do 'on special days",,that fits in with the Google logo on their main page. I mentioned I thought it was flash embedded but in fact I am guessing it was java enabled somehow as Jeff mentioned here,cause when right clicking the animation, did not bring up the 'about flash' menu. It was a very simple 'bucky ball' animation,9/5 was bucky ball day,whatever that is?,that looked something like a slow spinning globe,FYI. It did in fact bring the two TC's to almost a halt until eventually you could navigate to even another link on Google's main page,that took you to say Apps,or something different than the actual Google main page. FYI. When running top with this page opened up the server load was not anything out of normal as many times Firefox process shows anywhere from 35% cpu to 90% cpu which is always the case. I did not have time to do a 'source' of the page to try and see what was put together,on the page. It sure did hammer the TC's though. Seems odd that a low powered TC that can run youtube fine, this simple animation takes it down?

The best solution known at the moment is to use a series of plug-ins for your browser. See: http://theoldgoogle.blogspot.com/ There used to be a simpler method, but Google discontinued it, so now we're all stuck like this. Even those of us not running on TCs want the simpler, faster access without all the "effects" Google has been rolling out.

I do not mean to make such a big deal out of a 'one day' thing via Google. The point is, if this would have been on an actual school day for example,my phone would have been ringing non-stop,"something is wrong with these PC's" etc,etc... As Google is set as the home page on all severs of course,:-). And at that point it would take a while to decipher what was actually taking down the server/TC's. I need to win the lottery!

Once again sorry for the slow reaction and i hope to have LTSP 5.2.4 in F14 asap. - -- Gavin Spurgeon. gspurgeon at redhat.com Red Hat GLS Instructor EMEA Red Hat UK Ltd 64 Baker Street 4th Floor, London, W1U 7DF Mob: +44 7841 231160 Desk: +44 0207 009 4429 (Direct) Tel: +44 1252 362709 Fax: +44 1252 548116 Registered in England and Wales under Company Registration No. 03798903 Directors: Michael Cunningham (USA), Brendan Lane (Ireland), Matt Parson (USA), Charlie Peters (USA) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ iEYEARECAAYFAkyGDMcACgkQvp6arS3vDir1UgCff4U8RGUYGRq7BFNnJDdQnEg4 N/AAniyA0HDDNFCBlqLpIxwOq0YZVs2L =Q+WX -----END PGP SIGNATURE----- From brcisna at eazylivin.net Tue Sep 7 11:18:01 2010 From: brcisna at eazylivin.net (Barry Cisna) Date: Tue, 07 Sep 2010 06:18:01 -0500 Subject: [K12OSN] LTSP on Fedora13 - users can't login Message-ID: <1283858281.18540.17.camel@hi2.wc235.k12.il.us> Brian, Is root able to login at the console with no problems? Is this system one that you migrated the existing users/imported from another server from a previous version of Fedora? Is there any difference if your select KDE as the login session( versus Gnome)? Make sure in your /etc/hosts you have the following entry at the top of the file: 127.0.0.1 localhost.localdomain localhost machinename machinename.domainname ,,,,# 4 name entries here What happens if you create a new user from the users and groups gui and try logging in? Make sure SELinux is disabled as well as iptables is stopped( until you get this figured out). What is the mask of the *users* home folder?,,,Change to 0700 if not this.

Perhaps a button for Google/m on the Bookmarks toolbar (which is then pushed out to all users $HOME) would keep most users from typing in google.com in the location bar--most people would rather click than type--particularly if typing in the URL results in awful performance because of the bells & whistles.

Once I have a 100% working copy for x86_64 I will build all arch. The issue is all my testing systems and indeed my own laptop run x86_64 so while I am constantly rebuilding to work out the issues with the up-stream code, It is much faster to just build the x86_64 and test. Once I have the package fully ready it will be pushed to the official Fedora Repo's and it will then be available on all Supported arch's It shouldn't be to long now, I am almost done with the changes needed to the up-stream code and then we will all be able to test and play.

Look at the output of cat /proc/cpuinfo to see if it is. 2) does running top indicate the offending task? I've seen bizarre things like a couple of daily yums backed up behind each other overwhelm the cpu. 3) Any reason not to run RAID 1 on this server? You actually get better read performance (even though writes suffer a tad) plus the peace of mind. Also, have mdadm email you if a drive drops out - iirc, see mdadm.conf and add MAILADDR your at email.com to the bottom line. regards, William On Thu, 2010-09-09 at 12:00 -0400, k12osn-request at redhat.com wrote: > From: Barry Cisna > To: K12LTSP > Subject: [K12OSN] Sever load , calculating > Message-ID: <1283975678.1251.17.camel at localhost.localdomain> > Content-Type: text/plain > > Hello All, > > Server: > Intel Xeon 2.4GHZ - smp- 2.6.18-194 kernel > ( As i see it Linux sees/dmesg this as a single processor,even though > the smp kernel gets installed?) > 2GIG ram > (2) 500 IDE HD's > (2) 10/100 nics 1 activated > LVM /ext3 (no md raid) > Centos 5 (updated) 5.5 > > > Wondering if anyone can shed some light on my wonderings here. > Over the summer i rebuilt our school's file server with bigger HD's > (2) > 500 gig PATA/IDE,and this time updated the CENTOS 5 install to 5.5 > along > with the latest version of Samba as well.

OK, I did find a couple interesting things in regards to CPU info. (This is listed in dmesg as P4/Xeon Extended,,blah,,blah,,,) When doing an cat /proc/cpuinfo The OS is seeing the processor as only 1,so I must have jacked upped and didn't enable 'hyper-threading' in the system bios.

And what kind of times do you see as the lower number from 'htparm -t -T devicename'? If it seems low, (below 50MB/sec or so), look through dmseg or /var/log/messages to see how it is detected. You should see something like: hda: 488397168 sectors (250059 MB) w/8192KiB Cache, CHS=30401/255/63, UDMA(100) If it isn't UDMA(100) or higher you might need a newer controller - or lower modes can be triggered by a bad or old style cable. -- Les Mikesell lesmikesell at gmail.com From gspurgeon at redhat.com Sat Sep 11 09:58:16 2010 From: gspurgeon at redhat.com (Gavin Spurgeon) Date: Sat, 11 Sep 2010 10:58:16 +0100 Subject: [K12OSN] ltsp-5.2.4-5.rpm's ready for testing (i686 & x86_64) In-Reply-To: <4C8A2910.1040208@redhat.com> References: <4C6932E8.5080605@redhat.com> <4C860CC7.6030802@redhat.com> <4C874713.6040509@redhat.com> <4C8A207F.1050001@hanzlici.cz> <4C8A2910.1040208@redhat.com> Message-ID: <4C8B52B8.60907@redhat.com> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi LTSP/Fedora Community.

On both of the HD's *cached reads* they are doing a respectable 870mb/sec 2. On both Hd's the *buffered reads* they doing a sucky 250kb/sec !!! This is with no one accessing the server too. Anyone have any ideas as to why the buffered reads are so pathetic? These are a pair of new a couple months ago WDC drives. I used an 80 conductor IDE cable. Is it possible not having hyper-threading enabled in the system bios(I think) that this is tanking the buffered reads? dmegs shows drives are doing UDMA 133mhz. CPU hyper-threading disabled,,,:(. hda: irq timeout: status=0xd0 { Busy } ide: failed opcode was: 0xb0 hda: irq timeout: status=0xd0 { Busy } ide: failed opcode was: 0xb0 hda: irq timeout: status=0xd0 { Busy } ide: failed opcode was: 0xb0 hda: status error: status=0x58 { DriveReady SeekComplete DataRequest } ,,* many lines of the above failed opcode hda* hdb drive shows none of these errors..? Looks like something is haywire with hda drive to me,or is it simply never 'catching up' from disk writing? I have noticed when in the server room the HD light on this server is in fact running like mad,but not all the time. I have not gotten any complaints (yet) of slowness in regards to file access but I cant imagine it can be anywhere close to what it should be with these readings. Bottom line I am kinda stuck as of now as this is what I set up. Sorry for long post again.

I followed the installation instructions at https://fedorahosted.org/k12linux/wiki/InstallGuide 2.

I continued the install procedure.

Aborting... /opt/ltsp/images did not exist. I created the directory, and then the command worked. At this point I could successfully boot the thin client, and get the blue k12Linux login screen. However, I am still having the problem, mentioned in my previous post, that for any user who tries to login, I see the message: Verifying password, please wait. The screen goes black for a moment and flashes a message (too fast to be readable), and then returns to the blue login screen again. This happens with all user accounts, so nobody can login. I was having this problem when I installed ltsp-5.13-1 from Fedora 13, so I don't know whether this is a problem with LTSP per se, or something else that isn't configured properly on my server. I tried suggestions posted by Sergio Chaves (re-running ltsp-update-sshkeys and ltsp-update-image), and those posted by Barry Cisna (eg. creating a fresh user account) but none of these things has made it possible to login. Further ideas would be welcome.

The reason for this is the blue IDC connector ties the ground plane together. Is the cable <= 18"? Are both drive on the same controller interface? e.g.: Primary IDE... To get maximum throughput out of two separate drives, I would place each on a controller as the master, then if I had to have a CD drive, I would add it to the Primary IDE as a slave. If you think you might be swapping drive around from time to time, you may want to go the CS (cable select) route, but you must make sure how the cable connects to the mainboard and then to the drives for proper operation.

Your suggestion below may be correct in principle, because I also found that I can't login to the server from another Linux box using X -query server_name :1 All I get is a black screen, that sits there until I return to the original console screen from which I launched X and kill the job. So it may be that FC13, out of the box doesn't allow remote xdmcp sessions. Some years ago I knew how to set that up, but a lot of things got moved around in Fedora. For example, /etc/inittab no longer launches X. So the result remains. I can get the k12ltsp login screen, but no users can login. Anyone know of a way to accomplish at the command line what Patrick was suggesting from gdmsetup?

How can I fix this? Is /home still exported on the server, or isn't it being mounted on the client.

I made a quick trip two days ago, to London, United Kingdom and had my bag stolen from me with my phone, passport, credit cards and my return ticket. I know this may sound odd, but it happened very fast. The embassy is willing to help by letting me fly without passport, but I have to pay for a return ticket and settle hotel bills, unfortunately for me, I can't have access to funds without my credit card. I've made contact with my bank via email, but they need more time to get me another card which i cannot wait to get. I was thinking of asking you to lend me some quick funds that I can give back as soon as I return. I really need to be on the next available flight. I'm going to need the sum of ?1,250 GBP, that's about $2,000 USD. I can forward you details on how you can get the funds to me. Hotel's desk phone: 011447901139407. I'm counting on you...

As for the clients, most machines of the last ten years have some sort of PXE option in the BIOS, sometimes referred to 'boot from LAN' or some such. If the machines don't have that, but have floppy drives, you can also use a universal boot floppy; I think there's still a link to it on the K12LTSP wiki. The downside is floppies can get lost, although some people just hide the whole floppy drive & disk inside the case where users can't get to them. Nevertheless, a NIC with a boot prom is nice, and quicker than using a floppy; www.disklessworkstations.com has them for US $30.

Buying a brand new Intel D510MO for $80 (http://www.newegg.com/Product/Product.aspx?Item=N82E16813121399&Tpk=D510MO) will give you the PXE bootable gigabit Ethernet you are looking for, plus a dual core CPU that will probably outclass most 5 year old PCs, and it will save about $60 per year in electricity (assuming 24x7 operation and about $0.10/kWh electricity rates). That plus it works out of the box so no mucking around with PCI cards, boot ROMs, strange video, flaky hardware etc., and of course it is fanless and small. If you don't need dual core and gigabit you can buy the even cheaper D410PT at $65 (http://www.newegg.com/Product/Product.aspx?Item=N82E16813121398&cm_re=D410-_-13-121-398-_-Product) Since I didn't need the dual core CPU for most of my clients I ended up buying the D945GSEJT instead. It has gigabit Ethernet and also has dual head VGA+DVI video, draws only 12 W and fits in the extremely small Morex T1610 case. I had access to a bunch of old PCs for my LTSP setup and I chose not to use any of them since they ended up being more expensive than buying new.

I've done this with some older 4GB hard disks with excellent results. You end up with an "EtherBoot hard disk" which of course will not get lost. Downside is that power requirements for those older boxes are now about as high or higher as the newer low-power ones. And the graphics is better now. But on a budget, this remains a great solution, especially if you're using K12LTSP 5EL...which I do. Peter's right, the clients don't really need gigabit. 100Mbps is quite sufficient for LTSP purposes, even for games like TuxType. --TP Peter Scheie wrote: > Generally, it is only the server that needs a gigabit card. 100Mb is > usually sufficient on the client.

We've got the same problem on 64-bit clients. 32-bit ones seem to work fine. reb From cisna-barry at wc235.k12.il.us Thu Sep 30 11:14:01 2010 From: cisna-barry at wc235.k12.il.us (Barry Cisna) Date: Thu, 30 Sep 2010 06:14:01 -0500 Subject: [K12OSN] still no usb! Message-ID: <1285845241.30475.8.camel@hi2.wc235.k12.il.us> Mathieu, try the following on a client. 1. Plug a usb stick, into the client usb port. 2. On client in a terminal run 'mount'. 3. See if at the bottom of all the drives mounted you seem something similar to the following line. 4. fuse on /home/username/Drives/Removable_Device_62_Mb type fuse (rw,nosuid,nodev,user=username) I am guessing you will NOT see this. If you do not, it would appear that something in the upgrade process knocked out the fuse libs on your 64-bit system. This will narrow things down a bit but to find the root cause is going to be tuff without lots of rifleing through rpm's.

I am not entirely 100% sure I understand the relationship between the BIOS settings and the network card -- am I correct in understanding that if the "boot from LAN" option exists in the BIOS, then ANY network card would work, or do I need both the "Boot from LAN" option *and* a "PXE-capable" network card?

It's a perception issue basically. While you are correct that a new motherboard will cost me $80 and save me $X in the future, it will still cost me $80 now. That $80 I can't get approved -- not possible as I've already tried. The best option to maintain good performance is to take these new computers we just received, and -- while spending as little as possible -- maximize their performance. The server already has the maximum amount of RAM loaded into it, and has 2 gigabit network cards. All the switches are gigabit also. So the best remaining option is the NICs inside the clients.

There is a great little floppy image (which I just tried to find again but can't online) that you write to a disk and then you just pop it into the computer, reboot, and it loads up and asks you which drive to install the image on -- ./sh /dev/sda and voila! It writes to the hard drive the necessary data to boot PXE. So basically the same thing you have done, but perhaps more user-friendly. I'll try to see if I can find the link for it and post it.

I think it would be rare for a client to use more than 100Mb - or for the server to be able to deliver it to more than a few clients at once. In older machines the video cards might make a more obvious performance difference. Or spreading the server storage over more drives. -- Les Mikesell lesmikesell at gmail.com From news at siddall.name Thu Sep 30 17:15:45 2010 From: news at siddall.name (Jeff Siddall) Date: Thu, 30 Sep 2010 13:15:45 -0400 Subject: [K12OSN] Recommended Gigabit Network card?

I think the BIOS setting only applies to the onboard NIC. However, if it has an onboard NIC with a "Boot from LAN" option then unless it is using something other than PXE (quite rare), you shouldn't need to buy anything. The only other BIOS setting I have found that sometimes needs to be enabled to make PXE work is the "LAN boot ROM enabled" or something to that effect.

Keep in mind though that going from FE to GE may not actually buy you any performance as there may be processing or graphics subsystem bottlenecks that are more of a limitation than bandwidth. Best bet may be to try one with an onboard NIC and see if it works OK. If not, buy a GE NIC and see if anything improves.

I finally was able to crack one of the machines open, and lo-and-behold, it already had a gigabit card on-board! Specifically the Intel 82573E gigabit NIC (more info: http://ark.intel.com/Product.aspx?id=26550 ). Granted it doesn't support Jumbo frames, but that would be looking the gift-horse in the mouth :) I guess I never expected that we'd get freely donated machines at the level of having onboard gigabit so I was assuming the worst. These machines are a bit more powerful than I thought -- Pentium 4 3.2 Ghz, 1 GB RAM, 250 GB SATA drives, gigabit NIC, onboard Intel 945 g/p graphics AND an installed ATI Radeon X1600 256 MB video card with DVI output. New keyboards, mice, and 19" NEC LCDs to go with them! So now that the gigabit issue has been resolved, the next issue to ask is: 1) Which video card to use? Onboard Intel or ATI card? 2) With such a machine, would it be beneficial to run something locally? Firefox perhaps? I'm currently running K12LTSP based on Fedora 10 Thanks Joseph On Thu, Sep 30, 2010 at 1:19 PM, Jeff Siddall wrote: > On 09/30/2010 12:16 PM, Joseph Bishay wrote: >> Hello Jeff, >> >> On Tue, Sep 28, 2010 at 8:38 PM, Jeff Siddall wrote: >>> Have you considered all the costs of using those old PCs? >> >>> I had access to a bunch of old PCs for my LTSP setup and I chose not to >>> use any of them since they ended up being more expensive than buying new. >>> >>> Jeff >> >> I have yes -- the issue is that this is a matter of numbers up-front, >> rather than long-term costs. ?It's a perception issue basically. >> While you are correct that a new motherboard will cost me $80 and save >> me $X in the future, it will still cost me $80 now. ?That $80 I can't >> get approved -- not possible as I've already tried. >> >> The best option to maintain good performance is to take these new >> computers we just received, and -- while spending as little as >> possible -- maximize their performance. ?The server already has the >> maximum amount of RAM loaded into it, and has 2 gigabit network cards. >> ?All the switches are gigabit also. ?So the best remaining option is >> the NICs inside the clients. ?Unless there is something else I've >> missed? > > Understood. ?Unfortunately some organizations have no long term vision. > > Keep in mind though that going from FE to GE may not actually buy you > any performance as there may be processing or graphics subsystem > bottlenecks that are more of a limitation than bandwidth. > > Best bet may be to try one with an onboard NIC and see if it works OK. > If not, buy a GE NIC and see if anything improves. > > Jeff > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see >
