Re: [Server-devel] [IIAB] [XSCE] RE: [UKids] Re: [support-gang] Taking OpenStreetMap Offline - DESIGN Call - Thur June 11, 10AM EDT / 2PM UTC
In IIAB we use a dataset of populated places to render at the highest resolution level, and render the rest of the world at a slightly lower resolution. Our highest resolution is high enough to see individual buildings. Our total dataset of rendered tiles for the world with detailed populated places coverage is 100GB. Another optimization we made for IIAB that contributed considerable dataset size reduction and helped with filesystem efficiency - we use the OSM meta tiles, which normally store 64 tile png images, but we modify them to store 4096 png images per file, and we made an optimization so that identical tiles are removed (think of all the blue of the ocean cover 75% of the earth). We use Leaflet as our javascript web front end, and it works quite well. -braddock On Sun, Jun 14, 2015 at 11:24 PM, Nick Doiron ndoi...@mapmeld.com wrote: I don't think there's any technical issues with rendering the world at 10 and specific countries at 16, other than the human knowing where they can and cannot zoom -- Nick On Sun, Jun 14, 2015 at 11:58 AM, Tim Moody t...@timmoody.com wrote: couple of observations: As expected, the new tiles have a lot more detail.

[Server-devel] How do the clients find a School Server in appliance mode
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi guys, I was introduced to XSCE Appliance Mode, which raises some great possibilities, but also some difficulties which need to be addressed, and which Internet-in-a-Box appliances have already faced. If a school server is installed on a network in appliance mode, and does not serve as the network's DNS provider, then it becomes very difficult for client XO's to find it since it has no name. We have faced the same issue with IIAB appliances, and compensate for it by providing mDNS/avahi and Samba NMB naming services. - From any Windows, Linux, or Mac when an IIAB appliance is on the network it is accessible from either http://know (Windows) or http://know.local (Mac or Linux) - our hostname is always know. Installing these services is just a matter of `apt-get install samba avahi-daemon' (Debian - something yum in Fedora). A big problem we've faced with IIAB appliances on XO deployments is that the OLPC OS does not turn on mDNS name resolution by default in /etc/nsswitch.conf (although the necessary software is installed). On the XO laptop, all that is required is a `yum install nss-mdns` to rectify the situation. If you are creating a new image for the XO laptops, I strongly urge you to install nss-mdns to activate mDNS resolution. It will make School Server, IIAB, or other content sources on the network running in an appliance mode practical without the need to resort to difficult DNS modifications and static IP addresses. The XSCE installer should similarly install samba and avahi-daemon on the school server to publicize the host name. If XSCE can be used in appliance mode with mDNS and NMB name resolution, I would be seriously considering discontinuing our (Debian-based) IIAB appliance hardware in favor of IIAB running on XSCE on something like a Cubox for all our IIAB deployments. I raised this issue on the OLPC devel mailing list last summer and it favorably received: http://lists.laptop.org/pipermail/devel/2013-July/037559.html - -braddock -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJSwkd5AAoJEHWLR/DQzlZuM9MIAJ2tYe3gDvA9vm9KvG4z3U6m WsnEQKXIDOSljqxdrVitDGgcxBLjKFFUXzevpBsr+ibhG2QdF2kN3IcihYv1hT00 ScChTpxqYcc3/PXipSoeZE8jUz+H8t/B6sI2+YpJQIf5ffAVP0PkAS+2rgmBdIWF 5zfs26pYnJVB00opZHFyKOes4GNNZqGnbpmVocKDS+o3jBYvxiTE98e51hB48dWu Fof95sKYg2S7FH3Z1LRQF/IiIZsDRqmezfqLgxykEBkW34g3RZfDadBcFxxNqkrv FJH/G2lMhpjGierfszVT8cf0LlCC4mUze7yMF8So6GdthL+zjBqzYcVVx85SkHw= =yHKO -END PGP SIGNATURE- ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

School Server Experts,
We are trying to deploy an Internet-in-a-Box (IIAB) network appliance
to an OLPC and XS school in Pakistan. (http://internet-in-a-box.org)
I need help getting them instructions so they can access the device
using their School Server XS 0.7
The IIAB appliance gets an DHCP lease on startup from their XS 0.7 server.
The IIAB appliance registers its name with the DHCP server as know.
In THEORY, on the XS, dhcpd should register the name know with the
named DNS server (ddns-update-style is set in /etc/dhcpd-xs.conf on my
own XS installation). Then students can access the IIAB appliance at
http://know
- From their reports, this appears to work initially, but after some
time (DHCP lease expires?) it stops working.
I'm looking for a simple solution to communicate to them to assign the
IIAB appliance a fixed IP address. It is currently not (safely)
possible to configure the IIAB appliance for a static IP. Then they
can just refer to it by IP.
I assume it should look something like:
host know {
hardware ethernet 00:03:6D:00:83:CF;
fixed-address 172.18.97.10;
}
added to /etc/dhcpd.conf
But with my very limited School Server experience I don't want to lead
them astray.
Any help appreciated.

Request for mDNS name resolution from Internet-in-a-Box project
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear OLPC Devel folks, Is it possible to enable mDNS name resolution in future builds of OLPC OS? Fedora and most Linux distros (not to mention Macs) support mDNS out of the box, yet for some reason it is turned off in OLPC OS. I believe all that is required is the addition of the nss-mdns package to the OLPC OS build. Enabling mDNS allows us to add an Internet-in-a-Box network appliance to an XO deployment network with zero configuration. The user just plugs our device into their network and browser queries for http://know.local simply resolve. This works on Mac and most flavors of Linux, and for Windows we provide an NMB name at http://know. But ironically the XO seems to lack any mechanism for de-centralized local resource discovery. Unfortunately, since OLPC OS does not resolve mDNS names we are finding deployments to XO schools are much, much harder. We are, for example, right now in the middle of a deployment to a large school with XOs in Pakistan. Instead of just plugging in the Internet-in-a-Box device, the people on-site need to reconfigure DHCPd on their CentOS XS School Server to supply a static IP to our appliance's MAC address, then use the IP address from the XO's browser. Not ideal, and I'm not sure they will succeed. A successful deployment of Internet-in-a-Box to a Windows-based school in Sierra Leone, on the other hand, was trivial.

Re: [Server-devel] A Path to Pathagar.
I'm curious how Pathagar may be applicable to our Internet-in-a-Box (http://internet-in-a-box.org). Can it scale to the 40,000 epub books in Project Gutenberg? thanks, Braddock Gaskill On 06/04/2013 01:46 PM, David Farning wrote: One of the additions to XSCE 0.3 is the ability to add services to XSCE without having an intimate knowledge of the entire server. Our first real test of this is the inclusion of Pathagar as a bookserver. For the last three releases the XSCE project has focused on the basics: 1. Network connectivity within the classroom. 2. Internet access were available. 3. Modular structure. This has been the boring framework stuff which will enable the fun user facing stuff like Pathagar to work. Pathagar is a simple bookserver. In this case, simple means rugged and maintainable. Pathagar has three purposes; browse, search and download digital books from a server. In the basic use case a librarian or curator places digital books in a directory on the server. Students can then browse, search and download from their web browser or bookreader software. Technically, most of the pieces are in place: 1. I believe the XSCE needs a bit more work handle external storage. (Not barfing if the USB connection is bumped.) 2. Pathagar is fully functional. The remaining steps will be to: 1. Validate Fedora packaging. 2. Create the glue code to add Pathagar to XSCE is a plugin. 3. Validate loosely coordinated release. 4. Test, test, test. Technically this seems pretty straight forward. The more open ended issues is curating content.

Re: [Server-devel] 1TB drive of quality open content on XO/XS--won't boot
Hi James I'm using OpenFirmware Q7B26 EC Firmware 0.4.03 I have tried turning the boot flag off on the NTFS partition, but it still dumps me to the OpenFirmware ok prompt.

Re: [Server-devel] 1TB drive of quality open content on XO/XS--won't boot
Hi James, I flew home from the XS-CE hackathon yesterday so unfortunately no longer have an XO-4 to test with. So I can't create you a known-broken USB image of reasonable size. I formatted the 8GB USB stick to NTFS under Linux using gparted (so mkfs.ntfs I presume). The fdisk -l is below. I did not touch or add any files to the partition after formatting. The Seagate Wireless Plus USB harddrive which also had the boot problem had an NTFS partition formatted at the factory, but was later resized by me using gparted. sudo fdisk -l /dev/sdd Disk /dev/sdd: 8004 MB, 8004829184 bytes 1 heads, 16 sectors/track, 977152 cylinders, total 15634432 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d606e Device Boot Start End Blocks Id System /dev/sdd1204815634431 78161927 HPFS/NTFS/exFAT On 05/13/2013 03:13 PM, James Cameron wrote: Thanks! I acknowledge the boot flag removal did nothing. This points me away from the part of Open Firmware that recognises that flag. I'm sure I can fix it as soon as I can duplicate the problem. But I've been unable to duplicate, possibly because I don't have the same NTFS software as you. I'd like to check the partitioning as well as the filesystem, because Open Firmware tries both in sequence. It might be reacting to the partition table rather than the filesystem. For that I will need a disk image, but as small as possible because I'm quite remote. Could you please pick the smallest USB available drive you have, (1) erase it thoroughly, (2) format it to NTFS in the way you usually do, without adding any files, then (3) prepare an image, (4) compress it with gzip or zip, (5) check that the USB drive does cause the problem still, and (6) provide me with a link to download? If anybody else has the time to do this, feel free to contribute. I've raised a ticket to track the problem: http://dev.laptop.org/ticket/12678 Some suggestions for capturing the image: 1. to erase a USB drive thoroughly, using Open Firmware, see http://wiki.laptop.org/go/Forth_Lesson_23#erase_a_device or in Linux use sudo cat /dev/zero /dev/YOUR_DEVICE where YOUR_DEVICE is the name that Linux has chosen for it, 2. (no suggestion), 3. to prepare an image on Linux, use sudo cat /dev/YOUR_DEVICE image, 4. to compress, use gzip image, 5. checking it after making the image ensures that any changes made accidentally by Open Firmware are not included in the image, 6. attaching the image to the ticket may be helpful if you don't have any public place to leave it. (and a comment, the support for NTFS in OLPC OS kernel is not pertinent to the problem I wish to solve.) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
