[Server-devel] XSCE 0.2 - Network problems running xs-setup
Hello: I ran into a few problems when trying to install the XSCE 0.2. I downloaded the repo and installed, during the installation process i got this messages, but apparently everything was installed correctly. http://pastebin.com/srwDn6wX I'm running in a HP DV4 laptop with Fedora 17 (security spin, i'm downloading the std version), it's connected to the internet with the wi-fi, and during xs-setup, connection is lost for some time (20-30 secs aprox), it stops and starts Networkmanager apparently, but is long enough for the script to fail at downloading the required software, and installation fails. I think is during xs-setup-network http://pastebin.com/7YTFHLL7 I'll be poking around to see if I can connect to internet with a cable, or pehaps give it a "sleep" to the script before downloading, if you could point me into wich file should i change. cheers -- Rodolfo D.

[Server-devel] Schoolserver development in Uruguay
ly need to send a guy (not a sysadmin) to go, insert a CD, next, next, next, voila.. even when changes need to be done.. they should be done in the way that can be applyed to the Installation CD (or installation procedure) rather then installing, and later updating with remote control Remote control is the best solution for problems to be solved in real time, or for deploying new content when an XS is already installed and working, but there could be other ways Paraguay in that sense did something really cool.. install the schoolserver _in house_, update it and send it to the field, but in the fild had to go somebody that could make the adjustments for the network to work, and that simple task was very difficult sometimes, and updating the leases and content when no conection is available is not fun either. > == Content management == > > Paraguay seems quite happy with Plone, but frankly I can't understand The plone deployment was based on a decision to give the schools a simple CMS, not simple in deployment, but simple in using, using a plone CMS to create content is super friendly, but in time, none of the teachers or students got to used it (simple or not) > why.

They used this tool instead because they learned how to use it during teachyer training, and they like it, it had an issue that once with access you could delete your co-workers files, but they used it anyways > Oddly, I've not yet may anyone using Moodle.

When a CMS was proposed, and later plone was accepted, i recomended dokuwiki, but for personal reasons i have to say, i have experience with dokuwiki, and deployment, updating, backup and other stuff is super fast (because it doesn't use a database, uses text files and folder schemes), but a being a wiki, is not as friendly to the newbie, because of the special syntax and all > == Server management tools == > > Paraguay uses Puppet.

I would advocate for this tools anytime, anywere.. but the conectivity is an issue, specially for places were the laptop is intended to go. The idea of the schoolserver should be of a _standalone_ and autonomous with simple yet friendly solutions to help improve class Internet is a luxury that Uruguay has because of a deployment politics that thay have (or so i read somewhere). Paraguay has internet, not because of a goverment desicion but rather because of the good resource movilzation, finding the sponsors that will give the internet, becuase of the projects public exposure If i think about what deplying in rwanda, uganda or even tibet, where the laptop is intended to go. There is no internet there, so their experience should point us to some key features that need to be included in the schoolserver I'm sorry this got so long, but there was plenty to be said.. :-) -- Rodolfo D.

Re: [Server-devel] Samoa Deployment - planned hardware for 30 July 2010
I have some experience with networking and wifi links, and what Carlos
states is correct
Although ubiquity nanostations are used generally to make
point-to-point connections over a long distance ("long" compared to
regular wifi connections made in the same frecuency with conventional
equipment). There are some models that can be used to connect large
areas, but AP coverage isn't your only issue
It is true that a number of factors influence the quiality of the wifi
coverage, but the general issue is this.. wifi connections are
bi-directional.. meaning that if your AP can reach a 1 mile radio, and
you computer antenna can connect to only 30 yards.. you need to be 30
yards from the AP. There are a number of other factors that can
improve or degrade the signal, but in empiric knoledge, this holds
true.
When you're thinking about connecting a school, any conventional
AP/Router can work as long as you stay withing the 40 meter radio,
with 1 or 2 15 cm think wall in between, but laptops should be as
close as possible to the AP.. again.. empiric knowledge.
This AP close to ceiling hypothesis will be tested next ;-)

Re: [Server-devel] [Marketing] [SoaS] The next Step: v2 Roadmap
Hello all: I'm actually not working solely with Sugar, but with the OLPC deployment and the XS.. The feature that i found to be more important is the re-installing of the operative systrem, beacuse the whole platform is still a little unstable, the OS reinstall is very usefull.. but the restore of the journal is very VERY complicated Daniel Drake made a couple of scripts that were very usefull, which restores a journal to a temp folder.. and when booting looks for that temp folder in order to restore If i tryed to do it manually.. is very long and complicated process.. do-able, but if i think of a 9 year old doing it.. well.. it could be to hard So I think that is someting that we shloud be aiming at.. simple journal backup and restore.. and not only in an OLPC, or XS envoiroment for that matter.. so even in places without XS (for backup) or where reinstall is a fast and easy way to get a system up again.. the journal is the only place where all things are stored cheers..

Re: [Server-devel] backup server
The moodle directory is /var/lib/moodle, that's for the files and data, but the database, could that be backed up as a binary database file? i had some expriences with mysql (not ps-sql) that didn't work so well, should and "export" of the database work better for that? cheers..

[Server-devel] backup server
Hello: What should be backed up for a reintallation of the server? Or better yet, what would be the steps for backup and restore of the XS? I know that all backup files from laptops is saved in the /library/users directory, but all users and from the /etc/passwd? those are added through the registration process..if I re-regiter a latpop.. the home folder will remain as in the backup (/library/users/XX) and nothing would change? cheers..

Re: [Server-devel] Saludos desde Nicaragua, OLPC SERVER
I didn't fully understand what you said.. The main installation doesn't filter anything.. i think :S..it does use a squid proxy, but no blocking we later added squidGuard to do the redirection, you can look it up in our wiki, we added squidGuard because of our commitment to the educational usage of internet and also because of legislation saludos..

Re: [Server-devel] Saludos desde Nicaragua, OLPC SERVER
Hola desde Paraguay We're going to continue this convesation in english so others may understand.. we have some instructions in this page for you to look at, they're in spanish and parts in english, hope it works out for you, its based on XS version 0.5.2 http://wiki.paraguayeduca.org/index.php/Servidor you can skip the parts about puppet or the FQDN naming, the rest is standard for any schoolserver installation saludos..

[Server-devel] web file manager
Hello: Just wanted to let you know that we are using a php file manager to upload files to the schoolserver and later shared through the apache web server.. we're using XS 0.5.2 The project is called phpajaxfilemanager, and is open source, we placed in the /library/uploads directory in the schoolserver, don't forget to change permissions so apache can access them http://sourceforge.net/projects/pafm/ We create to aliases in the webserver.. using a config file like this.. we changed values for the php.ini file from this configuration, and applied only to the alias, so no other aplications (like moodle) would be affected by this changes # /etc/httpd/conf.d/002-uploader.conf Alias /upload /library/uploads AllowOverride All php_value upload_max_filesize 1000 php_value post_max_size 1000 Order allow,deny Allow from all Alias /files /library/uploads/files Options Indexes Order allow,deny Allow from all With this two aliases.. the teachers can use the "upload" interface wich has a very simple authentication.. and the children or other teachers can access to the "files" aliases, without having to authenticate, and they wont be able to erase anything, upload or modify anything I'll admit that is not the safest way to share files using the schoolserver, but it works fine for us.. do you think that are other ways of doing this?? are other deployments using different methods?? cheers..

Re: [Server-devel] Server configuration for static IP instead of DHCP
You have to create a file /etc/sysconfig/network-sripts/ifcfg-eth0-local and configue in it your static IP like any other fedora machine hope that works.. cheers..
