I have enabled ipv4_forwarding,in sysctl.conf and in iptables have set dnsmasq to -outgoing eth0 ( internal interface). 2. The laptops can ping both k12server nics/ltspbr0 but can not ping any public IP number. I know iptables/firewalling is hard to give advice on with the miriad of variables involved. Of course the actual TC's have no problem internet browsing. This is on both Linux and Winders laptops. Bottom line; K12linux server is not feeding non-TC machines dns info.

It doesn't want to work on usb wifi sticks which are a headache to get working usually anyway,but I did try on them as well.

Every I read to use iptables -t nat -A POSTROUTING -j MASQUERADE but nothing but frustration. Somewhere, I stumbled upon this version: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE --source 192.168.0.0/24 note the -- source, etc at the end. Obviously, adapt the 192.etc to your particular network layout. I edited the appropriate line in the old k12ltsp nat service and that solved it for me after weeks of banging my head against the wall. All the same, I'll give Peter's method a shot.

I am in the process of setting up my first f10-k12linux server (for my home use). We are using Centos5 still at school ,as well as what I am running at home for the tribe to thrash on,,:) I am about a year or more behind on doing this I know,but I am finding the ltsp5.x is going to render my poor little Ebox2300 useless. I have read on the k12linux wiki were most of the HPtx series are mostly done,as well. I have been doing some research into this and found that(with the same hardware), when booting a client,I do a network restart on the server before ,to clear the nics rx/tx figures,, that with ltsp4.x eth0 TX's about 65MB of data. On the ltsp5.x server the eth0/ltspbr0 TX's over 360MB's of data. This is just to get the client to a logged in desktop. My Ebox takes about 45-60 secs to get to a login with ltsp4.x and with ltsp5.x it takes about 3-4 mins. I did switch out the switch in between my server and the TC (upstairs/downstairs setup), to a gig switch thinking this may help a tiny bit even with the TC nic being a 100mb. It made no difference. Whats odd is I can have both severs running side by side,,have the Ebox boot from the Centos5 server then nx-client to the f10 server and web browsing is as fast as if you were on a latest greatest machine of any configuration. Of course this isn't practical but just saying. Anyway just posting some of what I have found in the last few days trialing f10 k12linux,,:) Sorry for the long post!

I was able to get a handful of MSI Wind barebones open box from Newegg for under $100. I only needed to add a stick of memory. As the essential hardware is the core of much of the netbook market (1.6 ghz Atom and Intel 945 video), these can act as thin, skinny or fat clients for all but the most demanding tasks. While they may not be in your budget at this price, what it means, going forward is that the price of new hardware for clients will become decreasingly a factor in the overall cost of a desktop infrastructure. If you add what is happening with AMD and with ARM processors, I'd be willing to say that client computing will get quickly fatter over the next several years. 2- I've not had the opportunity to test it but I've heard that FreeNX, as much as I absolutely love it, doesn't scale well. You may want to see if you can get 20 instances running on a server without significant lag before you commit to that direction. For a couple of clients, it can really help, though. I used to use it on a P! 166 laptop that was running FreeNX over wireless and the performance was surprisingly good.

Darryl. Do you have any parts numbers that you are using in the Itel Atom's mobo's? I assume these work with sound ' out of the box'w ith ltsp5? Also they do have pxe boot? Kinda strange when I look through lots of the pc's we have throughout the school that are not that old that are not pxe boot capable.

As the essential hardware is the core of much A regular mATX system from newegg $40 2.7Ghz AMD Sempron $50 Gigabyte MB (Gb nic + pxe) $50 Case+PSU+Keyboard+mouse $20 1 GB ram so for about $160 you can buy a system which is MUCH faster than an atom. You can use them for thin clients + local apps or diskless clients. It may consume a little more power but not a lot more. It's also upgradeable in terms of ram. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada From dbond at nrggos.com.au Tue Dec 8 09:43:34 2009 From: dbond at nrggos.com.au (Bond, Darryl) Date: Tue, 8 Dec 2009 19:43:34 +1000 Subject: what are you using for TC's In-Reply-To: <1260230474.24489.17.camel@localhost.localdomain> References: <1260136310.7369.58.camel@localhost.localdomain> <4B1D794C.4000404@nrggos.com.au>, <1260230474.24489.17.camel@localhost.localdomain> Message-ID: <4FCD5739EC65BF41A0831C7A016793045BF2550F7E@GPSMAIL2007.gps.local> The Aus supplier that I use has single and dual core Atom MiniITX MoBo from several manufacturers. http://www.auspcmarket.com.au/show_image_products.php?input[category_id]=361 The cheapest single core MoBo is $AU110 or about $US100 (with CPU), a stick of DDR2 and a cheap case makes a very fine thin client. Low (electrical) power and noise. Both the Foxconn and Gigabyte boot LTSP5 with PXE no problems.

Darryl. Do you have any parts numbers that you are using in the Itel Atom's mobo's? I assume these work with sound ' out of the box'w ith ltsp5? Also they do have pxe boot? Kinda strange when I look through lots of the pc's we have throughout the school that are not that old that are not pxe boot capable.
