WNP: python-uniconvertor enables inkscape to import CDR files
Dear list, one things teachers need occasionally is importing works sheets from collegues. As it comes to proprietary file formats, corel draw seems to be most tricky. Accordingly, it's nice to read about the Sk1 project, providing free software that is able to free documents that was secretly encoded binary before. Nevertheless, it is a pity, that the corresponding package python-uniconvertor is broken, as one can read in several forums and bug reports. There seems to be a workaround, developers, please have a look at: http://sk1project.org/forum/viewthread.php?thread_id=472pid=1108#post_1108 Thank you, Ralf (bug report in prospect) -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.

Fwd: Installation
---BeginMessage--- Hallo werte erfahrene Skolelinuxer, wir haben an unserer Schule - erst parallel zu einem auswärtig gewarteten Windows Netz - ein Skolelinux Netz aufgebaut. In den Biologie und Chemie Vorbereitungsräumen mit ein paar alten für Windows nicht mehr ausreichenden Arbeitsplatzrechnern, in 4 Unterrichtsräumen stehen Laptops, die unter Windows mit einem Smartboard verbunden sind. Die Rechner der Unterrichtsräume habe ich erst einmal parallel zu Windows (für manche Kollegen) als Disklesss Workstation laufen lassen. Nach viel Überzeugungsarbeit (und weitgehend problemlosen Arbeiten der Rechner) habe ich ein Laptop als reine Skolelinux Workstation umkonfiguriert. Bei der Installation wollte das System ganz zu Beginn schon firmware (von einer Diskette oder CD Rom haben (gab es natürlich nicht). Nun gibt es zwei Probleme: 1. Das Mousepad des Laptops funktioniert nicht (der Mauszeiger wuselt nur im oberen linken Bereich wahllos herum. 2.Zwar funktioniert das Smartboard als solches, nicht aber die zugehörige Stiftleiste (die Kontrollleuchte blinkt auch grün, kein Dauerlicht. Sobald ich dieses Laptop als Diskless starten lasse, ist wieder alles funktionsbereit. Das erste scheint wohl ein Treiberproblem zu sein. Kann es sein, dass im Kernel, den das Laptop als diskless lädt ein anderer Treibersatz drin ist als im Kernel, der für den Arbeitsplatzrechner installiert wird ? Wenn ja, wo kann ich den richtigen Treiber bekommen (2 Jahre altes Lenovo Laptop) und wie binde ich den dauerhaft in den Arbeitsplatz Kernel ein bzw. in das Installationsprogramm, da ich die anderen Laptops auch entsprechend umstellen möchte. Das zweite Problem (Stiftleiste des Smartboards) liegt wohl daran, dass der von mir heruntergeladene Programmteil zwar für den diskless Kernel richtig eingebunden wurde, nicht aber für den des Arbeitsplatzrechners.

September 2012 From: Wolfgang Höfer hoeferw...@t-online.de To: Mike Gabriel mike.gabr...@das-netzwerkteam.de, u...@skolelinux.de Hi Mike, hallo Liste Ich habe hier einige seltsame Erscheinungen, was wohl damit zusammenhängt, dass mir das Ineinandergreifen der verschiedenen Komponenten des gesamten Setups noch nicht klar sind. Es laufen eben Dinge (undokumentiert) im Inneren ab, denen man erst auf die Spur kommen muss. Ich hab mal eine Skizze von meinem Netz in den Anhang gepackt. Folgende Gedanken plagen mich. Wer ist der Cups-Server? Der Tjener kann es eigentlich nicht machen, weil er (bei mir) keine Maschinen in den 192er Netzen erreicht. Damit kann er die Drucker nicht sehen und auch nicht verwalten. Meine zwei Computerräume sind durch eine 24er Netmask voneinander getrennt = jeder LTSP muss ein eigenständiger CUPS-Server sein? DHCP Auf jedem LTSP läuft ein DHCP-Server (ist nicht optimal, weiß ich). Die Requests der Clients erreichen beide Server (sieht man im Syslog vom Tjener). Der falsche LTSP reagiert auch brav mit wrong net. Der andere LTSP liefert dann die Adresse aus. Die Info, welche Maschine (MAC) welche IP bekommen soll, die sollte wohl über das andere Interface vom Tjener ermittelt werden (oder aus dem eigenen Cache). Nun musste ich aus verschiedenen Gründen die IP der Drucker (im LDAP) ändern. Es war danach nicht möglich, die Drucker mit dieser IP zu versorgen. Ich habe die Dienste, die Server, die Drucker, ... neu gestartet - immer die alte IP. /var/lib/dhcpd.leases geleert - nie bekam der Drucker DIE IP, die im LDAP stand (ja, ldap2bind hab ich auch aufgerufen) NBD Am Ende des Tages hängen auf einem der LTSPs zahlreiche Prozesse, die dem User nobody gehören und den Dienst NBD betreffen. Ich habe am Samstag noch einige Fehler (von mir) im LDAP gefunden (IP-Zuweisungen zum falschen Raum). Nun muss ich diese Woche nochmal beobachten, was sich auf den beiden LTSP's abspielt. CFENGINE Kann man auf diese Weise Softwareverteilung oder zumindest Nachinstallieren von Programmen veranlassen? Das wäre unbedingt in die Doku aufzunehmen. DHCP + BIND In Gosa kann man bei der DHCP Einstellung zwischen (tjener) dhcp (tjener) intern (tjener) 10.0.0.0 (tjener) subnet.intern00 (tjener) 192.168.0.0 (tjener) subnet.intern01 (tjener) 192.168.1.0 Wählen. Wo liegt bei den ersten 3en der Unterschied, die anderen sind auch paarweise identisch. Wenn man den entsprechenden Bereich im DNS aktiviert (Checkbox rechts), dann ist der Client dennoch nicht über seinen Namen pingbar. (z.b. ping drucker2 geht nicht) - hier muss man dann den ganzen DNS-Namen angeben ping drucker2.subnet00.intern Ich bin nicht sicher, dass die gesamte Kommunikation im Netz diesen Namen verwendet. LTSP SSH hab ich bereits deaktiviert, hat was gebracht. War schon immer eine Engstelle. SET RUNLEVEL Ok, das Skript ist einfach genug - aber das wertet doch die IP-Adresse aus und übergibt je nach 10er oder 192er den Wert 3 oder 4 an den init(?) Prozess. Wofür braucht man dann den Runlevel-Parameter in der Appendline, wenn dann doch über die IP entschieden wird. Und dann ist mir immer noch nicht klar, was sich am Bootprozess ändert. Der prinzipielle Unterschied zwischen diskless und Thin ist mir schon klar - aber was ändert das technisch. Darüber findet man auch in der LTSP-Doku nichts - zumindest ich :) BIND Werden die verschiedenen A_Names im Bind dynamisch über die Netgroup-zugehörigkeit erstellt? Zumindest hat beim Tjener cservd und cups gefehlt. KDE Auch auf meinen Workstations eine Katastrophe. Nach dem Login folgt auf die Initialisierung der Oberfläche eine (mindestens) 30sekündige Totzeit. In der Zeit kann man klicken was man will, es passiert nichts. Irgendwann wird dann der Start-Button aktiv. So lange waret aber kein Schüler Viele Fragen, ich weiß. Aber leider keine Antworten dort wo ich sie hätte lesen können. Zum Systemgraben fehlt mir leider etwas die Zeit VG Wolfgang On 23.09.2012 21:11, Mike Gabriel wrote: Hi Wolfgang, On Mi 19 Sep 2012 07:13:00 CEST Wolfgang Höfer wrote: Liebe Liste, Eine generelle Verständnisfrage: Der Unterschied Thin-Client / Diskless-Client ist ja, wo die Anwendungen laufen ( so weit ich das weiß).

By moving away /etc/debian-edu/www/wpad.dat on the main server, the

block the entire browser.
The current wpad.dat look like this:

isPlainHostName(host) ||
dnsDomainIs(host, .intern))

The browser seem to become quicker by changing this to a simpler one:

Can you test if this help for you too? Replace the file

also for non-resolvable addresses and for local addresses?

Only later, I had to learn that some users were missing in my hand made list. Apparently there is a limit of 1,000 users when using ldapsearch anonymously. Using ldapvi, I managed to get all information I need, and could paste my grep-lines into one csv file. This time, I bound to DN-admin, of course.

You should be able to use a similar construct to verify that LDAP bind
works.
Another idea would be a missing SSL certificate for the server. See
/etc/init.d/fetch-ldap-cert for the details on how that is fetched and
stored on clients.
Okay, maybe php is missing ssl-module?
Good luck. :)

Re: Kturtle in Bengali...
Dear Joysankar, thank you for your work, having kturtle in Bengali, is really a great achievement. I am a teacher having translated kturtle commands into German years ago, so I wonder if your translation also includes commands (there used to be some issues with UTF8, hope, this is fixed now). I am just a user myself, but as I remember, your po files need to be uploaded by official debian developers into testing, in order to have these files included for the next release cycle. Don't know as for schedules; but please be patient. Until official releases, you might get some inofficial Debian packages that can be installed from corresponding apt-sources. Regards welcome, Ralf P.S.: Further reading to know about your language and its writing: http://en.wikipedia.org/wiki/Bengali_language One wouldn't guess it: Bengali is one of the most spoken languages (ranking sixth) in the world.

It should be easy to bind MRBS [1} to tjener's LDAP, whereas just teachers should be allowed to access the system.

Samba: Domain Skolelinux not available if IP beyond 10.0.2.239
Dear list, our Debian Edu system used to be stable like a rock. After holidays, I encountered an issue as follows: The last 8 of 20 clients in our cabinet cannot log in to samba, their message is domain not available. I checked cables and switches - and IPs (from 2nd boot partition running Debian Edu without problem), nothing that differs from other machines. It stroke me that all clients concerned were in an IP range of 10.0.2.240 upwards (static190). Then, I changed dhcpd.conf, giving those clients lower IPs (there was a gap in static62..70). And, indeed: Now those clients were also able to login! All butt the last one (that got no free IP in dhcpd). There were no other changes AFAIK, can anybody explain this behaviour, i.e. rejection of clients with specific IPs? Thank you very much, I like to sort out the origin of this issue ASAP, because I need to report tickets to our support compony (without giving them the chance to blame Skolelinux) Bye Ralf P.S.: Maybe there is a connection to this changes: - I added a course of 85 students, now we got 1000 users) - I added a corresponding share - another share (restricted access) is not available anymore recently, while testparm reports no issues, and any other share is working. -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.

db.intern was edited in June to add another

Dear Debian edu users and developers. It's been 2.5 years ago, when I joined an even older bug report for Firefox 2.0. These days I had to find out that it isn't fixed in 4.0 nor 5.0. For oranisations like us schools, this is a real show stopper, as users will have to wait for seconds until a new page opens (and in this time the whole Firefox/ Iceweasel GUI is frozen). https://bugzilla.mozilla.org/show_bug.cgi?id=235853 This bug is only visible if you use wpad.dat plus auto detect proxy settings in your browser. To witness the effect, just enter test in some search engine, and then click the first 4 hits using the mouse key in the middle (hence opening separate tabs for each hit). I bet you won't get to the 3rd hit, because you will witness the first freeze. The only work around is to use explicit proxy settings, which might be feasable - but complicated for big companies and schools. This is too bad, because the wide range of personal users don't suffer from this bug while potential multiplier of free software are deterred. https://bugzilla.mozilla.org/show_bug.cgi?id=235853 Please get more attention for this bug by voting for it, especially if you are concered yourself.

Re: Make LibreOffice part of Debian Edu
Am Dienstag, 15. Februar 2011 schrieben Sie: When I was printing the semester reports last week (from Windows - photocopy machine driver problem), I had to wait for frustratingly long for the new printing dialogue to respond. So long that I uninstalled libre office and went back to OOo. It was much faster for me to reinstall OOo than it was to wait for that thing repeatedly. Perhaps because it was a network printer? A windows problem? Whatever, I'm not in a hurry to inflict that on my school. I would rather wait for libre office to percolate naturally into debian, which is surely inevitable. Dear Nigel, thanks for your feedback, maybe really a windows issue? OOo had some shortcomings in its Linux version (e.g. file select dialogue), and as a teacher I appreaceate that LO now allows me - to print 2 (4,8,...) pages on a single sheet (this was really dreary, before, when I had to export to PDF and juggle with pdftools then). - actually print the same page twice on a sheet using the freeform text field for pages to print: Here you can now enter 1,1 instead of heaving to copy page one to have an identic page two. Also opening PDF files and SVG from anywhere works like a charm, and I think the pdf import looks even better, now... Just my few coins on this, but of course, LO must get into Debian ASAP. Please check out LO for linux, and get your driver problem fixed (we might find a solution together). ;) Regards Ralf -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.

moodle.skolelinux.org community -- or making money with free software
Dear list, this is just a slight idea that came into my mind during recent negotiations with local municipalities. I heard of schools that would pay several hundred euros per year in order to get access to a web hosted LMS like moodle. Their biggest objection was, that LMS accounts would fall apart from their local user data base (presumed they were synced in the beginning, that is). Well, I am one of those who managed to setup a local moodle, that was using our LDAP for auth. But in the end, maintainance (in my case) was one problem, and bandwidth (from outside) was even a bigger problem. Now, I wonder if there is anybody (maybe even SLX NO himself) who could imagine to combine bread with fun -- making money with free software for schools who demand a professional support, and provide free access for pupils of Skolelinux schools that want to join our community? I think of a moodle server hosted on the web - and some simple scripts to sync local LDAPs with the moodle data base. Schools could buy virtual classrooms - or just pay some rate per user... Well, of course, privace has to be a topic (so classrooms could be kept private, while users were able to partake in our community voluntarily). The pecuniar aspect is not my focus, but as I feel everybody is busy, anyway, it could be the initial spark... Now, let this idea settle, I will be on hols for a while ...

Fwd: [Swami-devel] Fast track to Swami 2.0
Dear list, I dare forward this announcement, because Rosegarden and other musical applications are part of our educational agenda, I think. SWAMI is an editor for soundfonts (formerly smurf). Kind regards Ralf -- Weitergeleitete Nachricht -- Subject: [Swami-devel] Fast track to Swami 2.0 Date: Montag, 4. Oktober 2010 From: Element Green jgr...@users.sourceforge.net To: swami-de...@lists.sourceforge.net Hello Swami development list! Its been quite a bit of time since my last activity on the project. I've been traveling in the western USA and taking a break from computer related obligations. During this time I went through a few name changes, but finally settled on the name Element. So from Joshua Green to Elimar Green to Element Green. I'm fairly certain this final one will stick for a while ;-) This break has also allowed me to collect myself a bit and discover what is important to me. I was reminded very recently about the unfinished state of Swami and it was with auspicious timing that Christian Collins made a generous offer of an incentive towards the Beta release of Swami 2.0. In summary, I've been dusting off the cob webs and knocking out tasks towards the goal of a release in the past week. Its hard to believe how long it has been since Swami 0.9.x was forked into what will be Swami 2.0, without a release. I think it has been primarily my perfectionism at fault. I was once again in the middle of a rather substantial code overhaul in libInstPatch and was beginning to think that I had bit off more than I could chew. So I ditched the overhaul after I came to the conclusion that, it is all pretty close to working and complete. While the programming API won't be perfect and will likely change substantially in the next major version, the primary goal should be to get things working and RELEASED! So I invite any and all those who are interested in helping out, to hop on the Swami 2.0 release train. What is needed: * Testing and identification of tasks to complete for 2.0 release. * Building and testing on Mac OSX and Windows (I'd like to have installers/packages available for these platforms upon release or soon there after). * Help creating an Ubuntu PPA perhaps to help expand testing audience. * Some cmake help. Considering converting to cmake prior to release. * Help creating a good users manual. Would be awesome if it could be integrated with Swami. Some things completed in the past week: * Re-created the Swami web site at http://swami.sourceforge.net (web site was down for a while!), now using MediaWiki. * Brushed up on my Inkscape skills and created a new Swami 2.0 splash image and logo (comments on them would be great) * Fixed many bugs and implemented many new features (see the Wiki TODO list page link below for details). * Most important feature added which was sorely missing was preferences save/load from XML. I created a Wiki page to track my personal TODO list items, here: http://sourceforge.net/apps/mediawiki/swami/index.php?title=Swami2Tasks I will keep it updated. If you see something that is not listed on there that you feel should be fixed or implemented for 2.0, please add it via the SourceForge tracker. I don't yet have any experience using the tracker, so it may need some admin before being completely usable. Onward to the stable fully functional release of Swami 2.0 real soon! Cheers.

It uses ghostscript to convert postscript files into PNG bitmaps, then calls percentblack or percentcolour to determine the percentage coverage. Prices may be independently determined for for each printer, with set rates for black and colour ink/toner and per-page. Bill calculation is quite CPU intensive so printbill allows multiple concurrent billing processes to be executed - jobs may not be printed in the order in which they are sent to the queue. On SMP systems printbill will happily make use of all processors if so instructed. Printbill can bill before or after printing, or can be configured to only perform accounting. It is possible to bill based only on pagecount, but although it is much faster, it is easy to fool and is not recommended. . Users pre-pay a quota and this is automatically decremented as they print - alternatively one may just do per-user and per-printer accounting with no billing. Various mechanisms exist for generating a quote. Printbill also keeps detailed statistics on printing habits which may be of interest to administrators.

KDE 3.5 Sessions - Autostart Restore
Dear list, for months now I am chasing a phenomenon that hinders users from login. In short: 1. Log in gives briefly a black screen, then login screen again (ltsp) 2. Removing .mozilla solves the problem in 99.9% of all cases. Now, I always have been wondering: why does KDE need/touch .mozilla to start a session??? The closest reason was: to restore a windows or autostart a process. I started collecting information about places where KDE saves corresponding information: /* KDE 3.5. autostart restore config files *** ~/.kde/Autostart/* ~/.kde/share/config/session/ ~/.kde/share/config/ksmserverrc / Deleting all those didn't help either. Also my suspiction about mozver.dat did not verify. When I try to login from a workstation, there _is_ a verbose message like: are you sure dcopserver is running / could not read session data etc. (no screenshot yet) Anyway, removing the folder .mozilla helps, and I start considering a nightly cronjob removing all .mozilla folders... If you, could please, tell me further KDE places where session data is restored, or config files that can be used to produce more verbose logging and direct it to a file Thanks a million Ralf -- To UNSUBSCRIBE, email to debian-edu-requ...@lists.debian.org with a subject of unsubscribe.

LTSP login blocked by .mozilla/mozver.dat ? (Re: failing ltsp login: xsession-errors / firefox kde?)
Hello, yesterday I did some testings with user accounts that were not able to log in to LTSP (password is accepted, a black screen shows up for a second, then the login screen comes back; no KDE splash screen or anything). There are no logs in .xsession-errors, so I logged in via ssh on tjener and tested those users that were not able to log in on ltsp on a terminal: User 1 could log in as soon as I removed his .mozilla directory. I double checked that quota was not the problem. Actually, I just renamed .mozilla to .motzilla; after logging out, I renamed .motzilla back to .mozilla, but this didn't block the account. So this makes me guess that some autostart process (or session restorage) was dropped when .mozilla was missing - and didn't step in any more after restoring .mozilla. For user 2, I checked .kde/Autostart first (nothing!), then removed some session links (cache, tmp) from .kde. No success. I renamed .mozilla/plugins and removed the latest biggest files in .mozilla/firefox. No success. Then I moved .mozilla/mozver.dat (which has global plugin paths) to /tmp - and voila: user 2 was able to login now. Same thing: After logging out and restoring mozver.dat, the account still worked. Searching the web brought me to this Gentoo bug that might be related: http://bugs.gentoo.org/90438 As I understand it, firefox wouldn't start if mozver.dat and others have wrong user IDs due to NFS mount (stale?).

Am Donnerstag, 28. Januar 2010 schrieb Petter Reinholdtsen: No idea what is wrong, but pam_ck_connector.so is in the libpam-ck-connector package. Is it installed? Okay, thanks for this hint, first time I read this line it was on tjener's syslog -- and there was no package containing this lib on my Sarge tjener. But now I see it comes from ltspserver00 -- and as it wasn't installed, I did so, now. It is used by consolekit, cf. package desc.: Description: ConsoleKit PAM module ConsoleKit is a system daemon for tracking what users are logged into the system and how they interact with the computer (e.g. which keyboard and mouse they use). . This package provides a PAM module which can be used for console logins. Graphical login managers should talk to ConsoleKit directly.

Re: rosegarden
Hi Nigel Am Montag, 25. Januar 2010 schrieben Sie: The teacher was very vague. He asked where kids can choose various instruments and play with the sounds, or anything like that?. He teaches grade 4 and 5. That means age 10 and 11. I imagine he has seen Garage Band on Mac, or similar. If you have any ideas I would love to hear them Okay, fist thing I recall is those musical activities (tomtom?) for the XO laptop. They should be available via sugar? Then, LMMS is a scoreless approach that could replace DJ software like fruity loops (IIRC that TM). I read about frescobaldi which gives a GUI for lilypond - and want to try this as well; should be quite educational for pupils 12+.
