Re: [Server-devel] Regarding my OLPC XS Wishlist
There's OBS (build packages for multiple distros) and suse studio, the latter builds isos, and if I understand it correctly not just suse isos, its kind of a drag and drop tool where you choose what your iso should contain And I would hardly say openSUSE is a minor distro... next to Ubuntu and Fedora, probably the most known and used... though I guess much more so outside the US, seeing as its German in origin... kind regards, David Van Assche On Thu, Jun 2, 2011 at 11:20 AM, Aleksey Lim alsr...@activitycentral.orgwrote: On Thu, Jun 02, 2011 at 06:29:51PM +1000, Sridhar Dhanapalan wrote: On 28 May 2011 08:31, Aleksey Lim alsr...@activitycentral.org wrote: On Fri, May 27, 2011 at 11:39:54AM -0400, Bernie Innocenti wrote: On Fri, 2011-05-27 at 21:14 +0545, Abhishek Singh wrote: Dear All, I've put down my OLPC XS wishlist at http://asingh.com.np/blog/olpc-xs-my-wishlist/ . Please comment upon it. Thank You. Thank you! Forwarding this to the Dextrose list as well. I've also CCed guys who do XS work in .au Abhishek: thanks for sharing your wishlist. From my side, I see the whole picture in case of school server like having: * sugar-server[1], the base of any school server. it doesn't provide stuff like moodle (too complicated to be basic) or puppet (useless on this level, since configuring sugar-server should be just install packages/iso and do some automatic work, the higher levels might user puppet or so) * any additional services that might be useful in some deployments but are not basic, eg, moodle or wiki. sugar-server should provide needed info via reliable API for these services. in my mind, such services might be formed as separate projects (like sugar-server-moodle) to make it possible to attach it on purpose (there might be useful configuration tool that is being used in sugar-server, mace[2]). * final products that include components on purpose (but sugar-server is a required one). It is entirely depends on local needs. We are looking to make our XS-AU[0] more modular to suit different use cases. Our initial goal (completed over a year ago) If I got it right, it is still the same OLPC XS code base but w/ tweaks? sugar-server in that case is a new project w/ more tough and localized design. work on a single interface to integrate well into existing networks. Installation is via USB and fully scriptable via kickstart files. The current XS is very monolithic and bureaucratic. It requires moderate sysadmin skills to install and maintain. Maintaining the presence service is cumbersome and impractical in our schools. The turnover of teachers and students is far too high to ensure that anything gets managed properly. We're looking to slim down the XS-AU such that we can have a simple collaboration server (which we currently call XS Lite) that is installable in a classroom as a drop-in appliance. ie, just having jabber server and somehow let students know where it is? is an ejabberd. btw, I'm planing to use Prosody instead of ejabberd. I have really bad experiance w/ ejabberd - on jabber.sugarlabs.org it eats too many resources for regular 10-30 online users. Prosody is slim and light app and it alsready works fine w/ sugar-0.88. Registration, Moodle, Squid, backups and so on are unnecessary. Each teacher can run their own server for their own class. Conveniently, this could easily run on an XO (XS-on-XO). in other workds there is no need in sugar specific stuff at all - just install jabber server from packages (maybe w/ sugar specific patches) and write its url on studensts' boxes. My own running though your wishlist keeping in mind sugar-server plans: 1) Porting XS to new version of Fedora sugar-server will be build on OBS[3] for distros that are being used in the field (deb or/and rpm based). So, downstream can just use these packages, add new one and create the final product (there is an idea to teach OBS to create isos for not only SUSE, obs is designed originally) You're using SuSE as a base? That sounds like an awful lot of work porting to a distribution that isn't widely used. Why not stick with the current platform, which benefits from Red Hat engineering and has a much larger developer, installation and user base? Not to mention that the XOs use the same platform, meaning that skills can be shared across client and server. OBS is not only suse (in fact, they renamed it from openSuse Build Service to Open Build System recently). In other words, it can create package for any rpm/deb based distro, but, afaik, it can create iso only for opensuse for now (and plan is looking how it might be done for other distros, but anyway using obs as a packages farm is good w/o having isos).

yeah I also had big problems with ejabberd in the beginning...

Re: [Server-devel] OLPC Moodle use
I would also point users to linux-for-education.org, which tries to be a little broader in terms of all the learning materials available, and isn't olpc centric. It does, however, have more olpc/sugar based learning materials than any other moodle install I know of. Having set up the majority of schools.sugarlabs.org and linux-for-education.org, I really think the 2 installs should be mirrors with the same content, to make it easier for content creators to choose where to deploy. Both sites have been neglected for quite a while, the main reason being I am the only one really paying any attention to deploying new learning materials, and I've been off doing other things, for which there seems to be a little more of a spotlight, something necessary, regardless of how selflessly time and energy is given to these projects. Unfortunately, since people don't seem to see the benefit of helping with the creation of documentation style learning materials, this is an uphill battle with no rewards. But we need this stuff, and even if its going to be just me adding content, then so be it, at least there is a place people can go to grab free in the full sense of the word learning materials. The sites (with an emphasis on linux-for-education.org) should be growing quite dramatically soon, due to needing to scratch our own itches (myself and some fellow users are starting up an IT school and are in need of free and open learning materials, so we will have to create what is not already there, ourselves) We will be basing the materials on ECDL and ICDL (European and Internatiohnal computer drivers license) as with that in mind one can get a diploma that is recognised in most places in the world. The ECDL curriculum is quite standardised and visible on its website, but there is still no location where one can download or interactively use the learning materials necessary to finally end up with the suite of diplomas available from ECDL.

[Server-devel] Fwd: [Ltsp-discuss] SolarNetOne solar-powered LTSP installation
This is very relevant to what's being done serverside for the XS... small form solar powered server that transmits networking up to 2 miles http://gnuveau.net/cgi-bin/wiki.cgi David -- Forwarded message -- From: Bjorn Helgaas [EMAIL PROTECTED] Date: Mon, Oct 27, 2008 at 11:23 PM Subject: [Ltsp-discuss] SolarNetOne solar-powered LTSP installation To: [EMAIL PROTECTED] Interesting application of LTSP: http://gnuveau.net/cgi-bin/wiki.cgi From the overview: The SolarNetOne ICT terminal network was conceived and designed to solve the challenging problem of how to provide Internet access and services to rural and developing areas where there is no existing power or communications infrastructure. This problem is solved by combining several powerful technologies: Photovoltaic solar electrical systems, GNU/Linux, 802.11a/b/g packet radio, commonly known as wifi, Power over Ethernet, and the MIT X11 windowing system. It has been described as an ISP in a box, for reasons detailed below. SERVER The SolarNetOne system incorporates a powerful server in a small form factor that acts as the core of the communications system. It provides mid to long range wireless internet coverage up to a 2 mile radius through its integrated high power 802.11a/b/g wireless access point and high gain omni-directional antenna. This configuration can be used to provide full internet access, including Voice over IP telephone service, to the immediate coverage area, which can be extended to longer ranges through the use of wireless repeater devices. Also integrated into the server is the capability for full end-to-end internet communications by means of its HTTP (web), SMTP (email), DNS (domain name system), and SSH (secure shell) server software. Additional internet services can easily be added to the network by use of the APT (advanced package tool) repositories of GNU/Linux software available worldwide. This is an integral part of the underlying Ubuntu operating system. APT automates the often difficult task of installing and updating software, making system administration tasks of installation and maintenance easy, particularly when critical updates effecting network security are concerned. The server itself can also be used as a network console for administration or day-to-day operator use through its integrated monitor, keyboard, and mouse. TERMINALS Another key feature of the SolarNetOne system is its network attached terminals, which provide traditional desktop services one would normally associate with using a computer, with several powerful, attractive, and popular desktop environments to choose from. It comes pre-installed with web browsing, email, office, multimedia, software development and web development applications, as well as a choice of over 15000 other applications to suit most any computing need that are free for download through the APT system. The terminals themselves connect to the system's Ethernet hub, which provides both network connection and electrical power to the terminals and their LCD monitors over a single CAT6 Ethernet wire. This eliminates wire clutter and the need for extra power wiring costs. They operate as thin clients with the majority of the workload being handled by the server's higher capacity processors, enabling superior performance per over than a standalone PC architecture and significantly lower maintenance workload than a similar solution of several personal computers. Also available is full sound support through integrated audio jacks, 104 key keyboard, laser scroll mouse and the ability to plug USB memory sticks into the terminals, allowing users to take their data with them round out the terminal's ability to provide a complete and rich user experience. SolarNetOne comes standard with 5 terminals, and can expand to as many as 48 terminals per server node. As an option in areas where allowed by law, an ATA phone adapter provides Voice over IP telephone service through a standard telephone handset. POWER SYSTEM The entire SolarNetOne system is powered by 12VDC electrical current supplied through the system's elegant solar power generation and storage subsystem. Using an array of photovoltaic solar panels, an advanced charge controller, ample battery storage, and a design focusing on safety, the power subsystem provides for all of the electrical needs associated with 24/7 server operation and 8 hours per day of terminal access. Integrated circuit breakers on every segment of the power sub-system provide the safest possible implementation. In addition to its excellent performance, the use of solar power means no fuel costs, no polluting emissions, and a long lifespan of up to 20 years of use at listed power ratings with proper maintenance. USER APPLICATIONS The SolarNetOne system comes pre-installed with a wide variety of user applications. For the user, these include: Mozilla Firefox suite for web browsing and email Evolution for email and

Been ruminating on this a bit. The more I think about it, the more clear it is that DG on the XS is not a good long term solution. - from reports, it seems to be fairly cpu and memory heavy - and its content scanning is fairly primitive - not bayesian For DG to be effective, I'd like to do Bayesian filtering, with the ability to train it. Or something in thesame family of strategies but smarter. The problem is that the XS will not have enough cpu/mem to handle this task. So it's a task better pushed to a proxy/filter upstream at the ISP network -- for any large deployment, we should start advising the local team to arrange with the ISP(s?) involved the co-location of 1 server. This server gives us an opportunity to perform - filtering at one central place = better scale up / scale out economies (making bayesian costs more reasonable) = larger scoring pool, so good/bad content gets flagged faster and for everyone = white/blacklisting is immediate and for everyone = better bandwidth/traffic efficiency - unwanted content never clogs the slow/limited school pipe = unsure if DG is the tool of choice here - smart upstream proxing = run an rproxy upstream or similar = provide seed content for downstream proxies to pull - With this setup, laptops can be configured to attempt to use the upstream proxy even when connected via a non-school AP. This way, the protections extend to kids accessing internet outside of school. This is somewhat hard to enforce - we are protecting kids that want to be kids. Once a kid is at a cybercafe and has the intention to sidestep the filter, the genie is out of the bottle: he/she could just use one of the other machines anyway. On every XS I want to include blacklisting facilities so that teachers can exert local control in a hurry, but that is simple, blunt, and hardly needs DG :-) In any case, we can still think of DG as a pilot deployment filter. cheers, m -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Re: [Server-devel] Aternative setting for eth0 on servers that are not #1
Hi Martin, Having worked in both 1 and 2 nic situations, what I've found often happens, and it doesn't really matter what distro or release, is that eth0 and/or eth1 often get blocked somehow... almost always something happens kernel side to disable one of the nics... This of course then catapults either the interior lan or internet access to no-man's land and we are left trying to reset the nics via tricky kernel commands (I found no way, other than to restart with a different distro, let it catch the nics with its kernel, then restart, to fix this) I've now seen it happen multiple times on the Fedora based system we had at OLE Nepal... plus that, though it makes sense in most situations to make the nics dhcp, with a server setup, so you can be sure which of the nics is acting as dhcp server it doesn't (you definitely don't want 2 on the network.) I'd vote to make both nics static and have an option for one nic in cases where bandwidth/traffic shaping is no issue... so within the setup script, ask what is wanted, giving advantages/tribulations of both... I've never had any problems with a 1 nic setup, except issues of security and no bandwidth shaping, but its difficult to measure how those things really affect the network without breaches and excessive you-tube usage, which a centralised dansguardian is usually gonna block anyway... just my 2 or 3 cents...

Re: [Server-devel] volunteer for offline Moodle
So the Google Gears rpm is finished (good lesson for me on how to package for Fedora) and we are working on the final obstacle for Browse, which is finding where in God's name the chrome subdirs are supposed to go... when thats done, we can create the browse rpm too... So I have a slightly different plan :-) This is great, but we should look for an interim solution to full blown Offline Moodle, something we can start using soonish... But maybe what you outline below is an interim solution... I guess we'll know when we start coding... First of all - you will need a good familiarity with Moodle, how it is used, and how it works internally. I don't know how much you know Moodle - my notes below assume a reasonable knowledge of the internal APIs. The first stage of the plan is to work on the main course page - look into the topics course format. The first step is to make that course format AJAXy/Gears-y -- there is an AJAX version of it but I am not sure if it is any good. The goal is to make it cacheable -- this is the lesson plan that Bryan was talking about a few days ago. Other good things may come with it (better ajaxy editing for teachers for example) but that is candy on the side. The main thing that *must* work well is being able to load that page when disconnected. Remember that the Jolongo people have already done a lot of this work, so if we can get a hold of what they've done, it might help. That said, they've not responded to my mails in a while now... [I am not sure how to trigger that with GG - to hook into the browser and say if host X doesn't seem present, load up this HTML+JS we cached here, under the privilege scope of the site..] Together with the course format, we will want to make mod/resource gears-cacheable. From all the Gears demos I've looked at, this has been the main focus of it so far... showing cached data locally and storing that into a sqlite database where necessary. The API seems straight forward enough, and even I can understand most of it (I'm not a born programmer...) That will give us 80% of the benefits for 20% of the effort - give or take some % there :-) We will want to be extra careful to make it in non-intrusive ways, so it is easy to incorporate upstream. 20% of the effort is still quite a bit of work - there are lots of details to work through. Once the above is done - we can tackle other modules, and perhaps some blocks, with better knowledge of what works well with GG and what doesn't. Some Moodle modules are a really bad fit for GG (mod/quiz), others will take some effort, but work great (mod/forum). The general model - as you can see - is one of caching locally, which simplifies things a lot. As you note, this will be a large long term effort, so we want to make sure that our work is not OLPC-specific. We might do things earlier than moodle.org but we sure want to have them helping with it mid-to-long term. Maybe we should talk to Moodle and make this official with them somehow? That might get some of the other projects to join our efforts.. It seems silly to have 3 forks of offline moodle, and from what I've seen so far the Gears method by far outweighs the benefits of the other methods... As we are caching stuff, and will only have small amounts of local data we need to push up to the server (like action logs), the storage economy is quite simple - we discard old stuff as we have to - we might define a quota there, but I think GG sets that for us anyway. For authentication, I am not sure at the moment - we'll cross that bridge when we get to it :-) but for OLPC it is an easy bridge due to the 1:1 and the related auto-login assumptions. Authentication is one of the first things that need looking at, since a Moodle user must login in order to download anything... Some of the first course material should probably be related on how to use Moodle and Offline Moodle... we could use that to create some skeleton courses that work both online and offline... How do we split the next workload?

Hello Tony check out gears.google.com to learn about google gears and you can join the Sugar mailing list at http://lists.laptop.org/listinfo/sugar Yep. That's a start. To coordnate work on Moodle, let's move that part of the conversation to server-devel@lists.laptop.org :-) Offline moodle is a bit of a deep pool, so some familiarity with moodle is a good starting point... Indeed, and the deepest part of that pool will be to fully understand gears and how it can recreate what moodle already does in a smaller, faster, and localised fashion. There is a possibility that the Jolongo people join in here and move from AIR to gears, since their bubble was burst concerning AIR not being open source. Also, their code will be the best place for a starting point, I think. I've mailed them again today to ask if they can give us that code (which they claim is open source) and whether they are going to seriously join the coding efforts in the gears camp... otherwise there will be 3 independent offline moodles being built (seems a bit of a waste...)

Re: [Server-devel] Wikiserver on XS
Moodle's integrated wiki is great, easy to set up and easy to use. I've used this with teachers and students without anyone having problems understanding how it works. Search functionality is also integrated from the start. The only thing is it is of course integrated in the Moodle package itself, but it is easy enough to add the wikis to the front page... that together with offline moodle seems to be an ideal solution. I'm currently testing both the offline moodfle plugin done by open university and intel, as well as the South American Jolongo developed using AIR, and both solutions seem promising for offline moodle. Both projects are still in BETA though, although the parties involved would be only too happy to get involved with something for OLPC... this provides an on and online wiki solution too (imho)...

Re: [Server-devel] progress on Moodle for the XS
- Single Sign On - Moodle will probably be the main SSO point, with MediaWiki and other tools either reading the SSO credentials from Moodle (via OpenID?) or directly off the client. Surely it makes more sense to use LDAP for single sign on, as it is supported by moodle and many more applications (email, posix, etc) out of the box. If you are going to read against Moodle's mysql database it seems like you might have to create an abstraction layer for every piece of sofware you want to authenticate against. - User management for the school server will happen via an extended version of the Moodle user management UI. The plan is to allow course membership in Moodle to be visible in the Sugar groups UI widgets (so you can share an activity with your course mates). Again, user management should really be done by an external database (ldap) that then feeds these credentials into whatever program needs them (moodle, email, computer logon, fedora commons) - Of course, regional deployments are encouraged to include content and sample courses within Moodle. - Some good discussions (for the Moodle.org site, login as guest) Devel list: Moodle on the OLPC server http://moodle.org/mod/forum/discuss.php?d=73022 K-12 forum: Hints on K-12 usage - Moodle and younger kids http://moodle.org/mod/forum/discuss.php?d=89165 Further into the future: - Moodle is moving towards having a good repository model. I am trying to help shape those efforts, and make the most in the XS. This includes teachers in the local XS being able to publish content/course materials for other teachers to use. - A mostly-disconnected Moodle client based on AJAX+GoogleGears or something similar. cheers, martin -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff -- Message: 2 Date: Fri, 2 May 2008 14:47:30 +1200 From: Martin Langhoff [EMAIL PROTECTED] Subject: [Server-devel] Layout for the yum repo To: [EMAIL PROTECTED] Cc: server-devel server-devel@lists.laptop.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1 Hi Dennis, I am working on preparing the xs-0.3 milestone, has some relatively simple changes (so far) and I am wondering how the repo layout should be setup. What I want to do is to - Build the LiveCD preconfigured to look at 2 repos, or branches in the existing repo: -- a pristine F7 branch in the repo that holds all the F7 RPMs -- an XS packages branch - For the xs packages branch, is should be looking at the 0.3 branch. I may make 0.3.x images with updated RPMs. Does that make sense? Our repo right now doesn't seem to be geared for this, but I am a bit lost as to the best way of reconfiguring it. What should we do? We don't have many (any?) legacy users in production that we need to support with updates (yet). With 0.3 I'll start supporting users more explicitly. In the meantime, we have a bit of freedom... cheers, martin -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff -- Message: 3 Date: Fri, 02 May 2008 10:39:49 +0545 From: Bryan Berry [EMAIL PROTECTED] Subject: [Server-devel] setting up project tracking app for OLE Nepal office To: server-devel server-devel@lists.laptop.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain This question isn't actually related to the XS, it is related to our internal office IT for OLE Nepal.

Re: [Server-devel] introduction...
At the moment I believe coping with fedora, would probably be more difficult than doing what you say you are already going go to do anyway. Why not let me start working on porting to debian, I will not be Nepal until June/July so have plenty of time. I believe, porting said packages to debian and running ebox is going to be easier than just looking at one of the existing builds, which might give me an idea of what XS does, but won't contribute in any way.

We are exploring a Debian move, and your experience will be welcome there, but at the moment using Debian for the base of the XS will mean that you will have to package independently - the kernel with custom drivers/patches - ejabberd - idmgr - a lot of configuration settings We will package all of those in .debs soon, but it is a ton of complex work for you if you want to do it on your own.

So here goes. I have been involved in the Linux community for a while, but my experience lies very much in the Debian/Ubuntu field, which I feel is far friendlier and more logical than the other distros. I have run my own IT company for 5 years, where we built bespoke programs, but mostly web solutions and administering accounts. Since then I administered a medium sized school, building the entire system based on LTSP (an amazing system) which really allows for the administration side to be a non-headache. I also taught IT for a year at this school. I've been following the list a little and I've taken a look at sugar which is very intriguing, though obviously very young still. I've been talking to Bryan Berry from OLENepal, and suggested installing a prototype XS server based on ebox with ubuntu or debian under the hood. The main reason is my knowledge in this area and the fact that I'll need to teach this to other sysadmins/teachers in Nepal. I know you guys have some ideas already, and you've already started on something, and I wouldn't want to just branch without synchronizing with the XS devel team. There are many aspects of the mesh networking aspect that I'm not to clear about, as I've never worked with this, though it seems pretty clear. I have always worked with webmin with my ltsp system without any problems, though I know how developers feel about its security and its internal workings, but lets be clear here, we're working with schools, not banks so I don't see the fuss. Anyway, I do think ebox is a good full solution that would do a better job than webmin in terms of security, and would be easily understood by most admins... With your blessign, I'd like to go ahead and build a prototype based on debian or Ubuntu for Nepal... with whatever help is needed from the XS devel team.
