[opensuse-marketing] larger openSUSE deployments?
Hi, I'm currently investigating whether and how openSUSE is used in larger deployments. Does anyone know someone who manages like let's say 30 or more openSUSE machines at once? I'm interested in e.g. what tools are used in such a scenario and what rough edges in the distro we maybe have that could be improved. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org

Hi Ludwig, Currently we have 350 elementary and junior high schools that use 21 PC loaded with openSUSE Edu Li-f-e 11.3 and 11.4 in their lab. In total there are around 2300 11.3 and the rest are 11.4. We maintain a local update repository in SLES 11 SP1. 11.3 is outdated now and we think to upgrade it to 12.1 but we still don't find the easiest way to do this actually. We think to upgrade all the PC locally using DVD. The problem is the schools are dispersed and the connection to our repository sometimes broken, we use our own private wireless network. This link http://ict-eqep.com/locations/map_350.html maybe can help you figure out how big it is. We use the PC for e-learning. We setup Moodle in 1 PC in every schools, synchronize it with the moodle mysql database in our datacenter and pull the e-learning data from data center. Other 20 PC then access the local e-learning material using browser. Actually when installing openSUSE for the first time for this huge amount we use tools like clonezilla because installing with other method, including network install taking too much time :) regards, -- medwinz -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org

Wow, that's huge! Wouldn't it take you years to take the dvd and drive to each and every school in order to start an upgrade there? Do you monitor all those installations after the initial installation somehow? cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org

Well, we let the teachers manage their lab however we train them how to doing the upgrade. We have a small script just to check whether the school server synchronize the e-learning data from our server. Because this setup depends on our wireless/radio network we use the rrdtool and monitor the status of school routers, radio etc. Anyway, I also use openSUSE for Asterisk in some places in Indonesia. It's a bit old but it runs well :) see this [1] and [2] And we have an old system with SuSE Professional 9.0 running a software (based on python) to turn-on the sirene on the beach when an authority announce the tsunami warning :) [3] [1] https://plus.google.com/photos/110554031246799489445/albums/5388219814816633...

Ah, ok. Some more questions came into my mind meanwhile (would be also interesting to hear how other people in the audience solve those). Since you use openSUSE Edu I suppose the teachers use iTALC to control the individual workstations, right? Ie monitoring what's on the screen, shutting the computers off if needed etc. Do the children have individual user accounts with their private home or do you use some shared user per workstation? How do you handle printer accounting? I heard that this isn't that straight forward with cups.

Hehe, that's cool :-) cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org

Yes we use iTALC :) We setup an LDAP server in every school, and put the account there. We use NFS server also to save the files if the teacher ask them to submit the work. All the users (11.3 or 11.4) can print to the share network printer. We set it up using YaST and the printers are either Samsung ML-2851ND or Xerox Phaser 3435 connect directly to the network with ethernet. We have one hardware problem though. Some of the schools use AIO Dell PC without VGA out or displayPort and the workaround for this is to use displaylink usb to vga interface. However it doesn't fully support linux yet. It only can show 1 screen. So if the teacher wants to use LCD Projector they only can see the screen either on the projection screen or in the monitor but not both [1] [1] https://plus.google.com/photos/110554031246799489445/albums/5543853263477202... regards, -- medwinz -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org

Out of curiosity, is there some further technical and/or administrative documentation of this project available apart from the links you already posted? I haven't been able to find any jogjabelajar.org or pemda-diy.go.id. -- Guido Berhoerster -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org

Hi ! I've a friend who manages a server infrastructure with almost only openSUSE servers in it. There are 29 servers running. Most of them are replicated in high-available clusters. He uses heartbeat and drbd for clustering. There are all types of servers here : DNS, mail, web, database... He has used the evergreen project (based on 11.2) during a long time, but has swtiched recently to 11.4, as it will be the next evergreen. The most interesting tools for him are YaST and zypper (of course). The release cycle seems to be a bit short for him, though... but that's why he's worked with evergreen, I guess ;-) he even contributes to it :-) Greetings, Agemen. -- To unsubscribe, e-mail: opensuse-marketing+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-marketing+owner@opensuse.org
