=== rhorstkoetter1 is now known as rhorstkoetter
[12:27] <rhorstkoetter> hi edubuntu team. I'm currently rather confused by a default edubuntu 12.04 setup and I hope to get help here.
[12:27] <rhorstkoetter> I had ubuntu 12.04 running with ltsp installed, thin clients booting etc (installed myself from scratch)
[12:28] <rhorstkoetter> now, I decided to switch to edubuntu and nothing works anymore :p I checked ltsp server during install and was greeted with a strange misconfiguration. let me explain
[12:29] <rhorstkoetter> edubuntu configured 192.168.0.254 as a dhcp server address in /etc/network/interfaces
[12:30] <rhorstkoetter> thin clients won't boot. then I discovered that dhcp server in /etc/ltsp/dhcp(d).conf was at 192.168.0.1 instead
[12:30] <rhorstkoetter> cannot work
[12:30] <rhorstkoetter> then I adjusted /etc/network/interfaces to be 192.168.0.1 to match the /etc/ltsp/dhcp(d).conf
[12:31] <jonathan_> that's odd, could you paste your dhcpd.conf file to http://paste.ubuntu.com/ ?
[12:31] <rhorstkoetter> but still thin clients won't boot while they did with my own setup (built from scratch)
[12:31] <rhorstkoetter> jonathan_: sure enough, wait a second please
[12:32] <rhorstkoetter> need to ssh (hope that works)
[12:33] <jonathan_> on the machine you could also type "pastebinit -i /etc/ltsp/dhcpd.conf"
[12:33] <jonathan_> and it would do it for you
[12:33] <rhorstkoetter> jonathan_: http://paste.ubuntu.com/1014673/
[12:33] <ogra_> heh, highvoltage incognito :)
[12:33] <rhorstkoetter> I haven't changed anything, i.e. it's just the default
[12:34] <jonathan_> (fine)
=== jonathan_ is now known as highvoltage
[12:34] <highvoltage> ogra_: I had a power failure at home and am connected via laptop :)
[12:34] <highvoltage> ogra_: hey you're not quite "ogra" either ;)
[12:34] <ogra_> ah, i saw you had issues with a panda ?
[12:35] <rhorstkoetter> highvoltage: this is /etc/network/interfaces http://paste.ubuntu.com/1014674/
[12:35] <highvoltage> ah that wasn't a panda, at least
[12:35] <ogra_> true ... but i'm to lazy to configure my IRC proxy for auth
[12:36] <rhorstkoetter> highvoltage: this has been the default http://paste.ubuntu.com/1014677/ - I should mention that edubuntu also switched network interface naming eth0/eth1 during install/installed system. thus the change from eth0 to eth1
[12:37] <highvoltage> rhorstkoetter: hmm, ok, that's not nice
[12:38] <rhorstkoetter> highvoltage: do you see any issues? what else you go wrong here? is there a need to rebuild the client chroot when editing /etc/network/interfaces while leaving /etc/ltsp/dhcpd.conf intact/default?
[12:38] <ogra_> no
[12:38] <rhorstkoetter> s/you/could
[12:38] <highvoltage> rhorstkoetter: I guess you should change "eth0" to "eth0" in your /etc/network/interface file and restart networking and the dhcp server
[12:39] <ogra_> did you restart the dhcpd after changing the config ?
[12:39] <highvoltage> (sorry I'm a big groggy just woke up and haven't had coffee so if there's typos, that's why :) )
[12:39] <rhorstkoetter> ogra_: I rebooted twice
[12:39] <rhorstkoetter> highvoltage: change eth0 to what? network configuration is OK already (matched to dhcpd.conf)
[12:41] <rhorstkoetter> highvoltage: eth1 is internal ltsp/dhcp interface 192.168.0.1 matching dhcpd.conf, eth0 is to the outside world
[12:41]  * rhorstkoetter confused
[12:41] <highvoltage> ah, your interfaces file that you pasted only had eth0 set to 192.168.0.254
[12:42] <highvoltage> 192.168.0.254 is usually the default used for LTSP setups
[12:42] <highvoltage> (for the server)
[12:42] <rhorstkoetter> highvoltage: wait please. we misunderstand each other
[12:42] <rhorstkoetter> sure I understand that
[12:42] <rhorstkoetter> but
[12:42] <rhorstkoetter> that cannot work
[12:43] <rhorstkoetter> if dhcp server is configured as 192.168.0.254 in interfaces and 192.168.0.1 in dhcpd.conf (and that has been the default after edubuntu came up for the first time) - how should that work?
[12:44] <rhorstkoetter> the eth0/eth1 switch was just another misconfiguration of edubuntu
[12:44] <ogra_> the server IP isnt configured anywhere in dhcpd.conf usually
[12:44] <ogra_> only DNS and gateway
[12:44] <ogra_> (gateway should point to the server IP though)
[12:45] <rhorstkoetter> ah, I see, you're right
[12:45] <rhorstkoetter> still, the setup doesn't work and it worked with a self-configured ubuntu install just half an hour ago with the same thin client (10, all working)
[12:46] <rhorstkoetter> so, I assume something is wrong with edubuntu default config (for me at least). what else may I try (assumed you testify my confs are correct)?
[12:46] <rhorstkoetter> rebuild the client chroot?
[12:47] <ogra_> how would that help ?
[12:47] <ogra_> and how does your client not boot, whats the error ?
[12:48] <rhorstkoetter> ogra_: it doesn't find the dhcp server
[12:49] <ogra_> and you are sure there is only one dhcp server running in your network ?
[12:49] <ogra_> PXE booting usually breaks if there are two that arent configured identically
[12:49] <ogra_> (pointong both to the same tftp server etc)
[12:49] <rhorstkoetter> ogra_: I also don't think it helps. I'm just out of ideas as the cabling is the same, the clients are the same, the server is the same. ubuntu self-configured worked, edubuntu does not
[12:50] <highvoltage> my guess is that since he has 192.168.0.x range IPs on eth0 and eth1, (at least from what I could put together), dhcpd might actually be listening on the wrong interface
[12:50] <rhorstkoetter> ogra_: certainly yes
[12:50] <rhorstkoetter> highvoltage: eth1 is 192.168.1.0/24, eth0 is 192.168.0.0/24
[12:50] <ogra_> it should tell to which interface it listens in the logs
[12:51] <ogra_> can you ping the outside world from the server ?
[12:51] <rhorstkoetter> highvoltage: the other way around sorry
[12:51] <rhorstkoetter> ogra_: yes
[12:52] <ogra_> then it looks like the wiring is fine
[12:52] <rhorstkoetter> ogra_: the wiring is just the same as before, as is the network configuration
[12:53] <rhorstkoetter> the difference just is that at first I configured ltsp myself in ubuntu and now I let edubuntu configure it
[12:53] <ogra_> did you check the logs = dhcpd should actually tell you things when starting
[12:53] <rhorstkoetter> during install
[12:53] <rhorstkoetter> ogra_: syslog?
[12:53] <ogra_> or messages, not sure
[12:54] <ogra_> i still use lucid on my server machines ... that predates the log changes
[12:54] <ogra_> (so i have  a daemon.log which you wont)
[12:56] <rhorstkoetter> seems (according to the logs) that dhcp listens on the right interface
[12:56] <rhorstkoetter> I mean interfaces and dhcpd.conf is configured correctly
[12:57] <ogra_> and you see it running with "ps ax|grep dhcp" ?
[12:57] <rhorstkoetter> I don't know. I guess I'll reinstall ubuntu and do the configuration myself again. that worked absolutely perfect
[12:58] <rhorstkoetter> 1375 ?        Ss     0:00 /usr/sbin/dhcpd -f -q -4 -cf /etc/ltsp/dhcpd.conf
[12:59] <rhorstkoetter> only difference between installs that I notice is an interface lxcbr0
[12:59] <rhorstkoetter> may this be an issue? not sure what it's for
[13:00] <ogra_> for LXC (linux containers)
[13:01] <rhorstkoetter> ok, need to research this to be honest. never heard about yet
[13:01] <rhorstkoetter> hm
[13:01]  * rhorstkoetter wants edubuntu to work ;)
[13:05] <rhorstkoetter> ok, I thank you for your time ogra_ and highvoltage. I'm still not sure what's going on here as I can't find errors in my configs, neither in the logs
[13:05] <rhorstkoetter> at least you also can't find errors. that's good :)
[13:30] <rhorstkoetter> hi. it actually seems to be a client related issue
[13:31] <rhorstkoetter> my collegue switched network cards and I was unaware actually
[13:31] <rhorstkoetter> I'm VERY sorry
[13:31] <ogra_> heh
[13:31] <ogra_> np
[13:31] <rhorstkoetter> switching network cards to the worse actually
[13:32] <rhorstkoetter> atheros > sis BOOM
[13:32] <rhorstkoetter> you may look (still) at the ethernet card switching during install/installed system
[13:32] <rhorstkoetter> should I file a bug report regarding that issue
[13:33] <ogra_> highvoltage, ^^^ ?
[13:33] <rhorstkoetter> i.e. eth0/eth1 switched
[13:37] <highvoltage> "09:29 < rhorstkoetter> my collegue switched network cards and I was unaware actually" <- that might have had something to do with it?
[13:38] <ogra_> only if he also switched the server ones
[13:38] <highvoltage> ah I see
[13:38] <highvoltage> rhorstkoetter: if you file a bug, please include the installer logs from the server,
[13:39] <highvoltage> (you could find them in /var/log/installer/ iirc)
[13:39] <rhorstkoetter> ok, I see
[13:40] <highvoltage> along with any other information you can provide, like that you chose to install LTSP, on which interface, what kind of network cards they are...
[13:40] <highvoltage> rhorstkoetter: I've tested the edubuntu installation on quite a few different real-life and virtual machines and haven't come across a bug like that yet, but nothing is impossible :)
[13:40] <rhorstkoetter> me neither yet
[13:41] <rhorstkoetter> now trying to get etherboot into the ethernet card bootrom
[13:41] <rhorstkoetter> cross fingers for me
[13:42] <rhorstkoetter> collegue ordered 30 of these and turns out sis900 pxe is pita
[13:42] <rhorstkoetter> i.e. not working
[13:42] <rhorstkoetter> lol
[13:43] <rhorstkoetter> there is a german saying that fits almost perfectly
[13:43] <rhorstkoetter> regarding the sis network cards
[13:43] <rhorstkoetter> einem geschenkten gaul schaut man nicht ins maul
[13:43] <ogra_> so you got them for free ?
[13:44] <rhorstkoetter> yes. as a donation
[13:44] <ogra_> lucky you them :P
[13:45] <rhorstkoetter> I am
[13:46] <rhorstkoetter> I actually plan a rather big ltsp/edubuntu rollout at a school and I'm currently testing the setup/gathering hardware at various places etc
[13:46] <highvoltage> ah that expression exists in english too: http://www.phrases.org.uk/meanings/dont-look-a-gift-horse-in-the-mouth.html
[13:47] <rhorstkoetter> highvoltage: lol, I see. I wasn't that sure if it's an idiom to the german language or not
[13:48]  * ogra_ didnt know there was an english equivalent
[13:48] <rhorstkoetter> ogra_: you're german?
[13:48] <ogra_> surprising, german spells rarely translate directly :=
[13:48] <ogra_> yep
[13:48] <rhorstkoetter> ah
[13:48] <rhorstkoetter> me too :p
[13:49]  * ogra_ assumed so :) 
[13:49] <rhorstkoetter> yeah, thinking about, I guess my nick is rather obvious
[13:50] <ogra_> could be dutch or belgian too though
[13:50] <ogra_> or danish ... just because there is an oe in it doesnt necessarily mean german ...
[13:51] <ogra_> but quoting german *and* having an oe in your name makes it pretty obvious :)
[13:51] <rhorstkoetter> true. at least I finally understood where "ogra" comes from
[13:51] <rhorstkoetter> true
[13:51] <ogra_> my first provider gave it to me for my first internet dialup account ever :)
[13:51] <ogra_> it just stuck since :)
[13:52] <rhorstkoetter> lol, mine has a rather similar history
[13:52] <rhorstkoetter> my pc-pool account in university
[13:53] <ogra_> :)
[13:53] <rhorstkoetter> although, if I remember correctly it has been rhorstkoe rather than rhorstkoetter
[13:53] <rhorstkoetter> anyways
[13:54] <rhorstkoetter> if I had the same isp back then I'd most likely be known as "rhor_" today
[13:55] <rhorstkoetter> just kidding
[13:55] <rhorstkoetter> almost sounds like thor
[13:56] <rhorstkoetter> another funny thing actually is that whenever I come across sis hardware (in whatever regard) I have problems
[13:56] <rhorstkoetter> interesting insight
[13:57] <rhorstkoetter> not too funny though as I just noticed that 3 new/donated laptops that just arrived here today also have the very same sis900 pxe bootrom and guess what?
[13:57] <rhorstkoetter> they don't boot (yet)
[13:58]  * highvoltage tries to avoid things with 'sis' and 'via' written on them
[13:58] <highvoltage> (but yes, given horses, etc)
[13:58] <ogra_> remember the ebox 1000 think client ?
[13:58] <ogra_> *thin
[13:58] <highvoltage> yeah :)
[13:58] <rhorstkoetter> yes, the given horses again ;)
[13:58] <ogra_> that was an *all SIS* device
[13:59] <highvoltage> yeah SIS Vortex or something like that iirc
[13:59] <ogra_> works fine as my firewall here though ... but i never managed to make something else out of it
[13:59] <rhorstkoetter> I had a medion desktop once and bought an usb camera for it
[14:00] <rhorstkoetter> I actually returned it twice to the store (silly me, that has been beginner days) until I found out the real cause of the problem
[14:00] <rhorstkoetter> guess what? > sis chipset. bought an intel pci usb card and it worked awesome
[14:01] <highvoltage> yeah, despite not agreeing with the anti-competitive nature of the intel company, I do like their hardware :)
[14:01] <rhorstkoetter> now the sis nightmare is about to return :) 30 pci network cards + 3 laptops with the very same bootrom = 33 potentially not working (yet) thin client
[14:02] <rhorstkoetter> highvoltage: me too. nowadays I try to exclusively use thinkpads just for this very reason
[14:03] <rhorstkoetter> but there is one positive thing to faulty hardware still
[14:03] <rhorstkoetter> the learning curve
[14:03] <rhorstkoetter> without things not working out of the box one wouldn't learn that much about getting them to work
[14:04] <rhorstkoetter> so, thanks a lot gericom, sis, medion, acer etc etc
[14:07] <rhorstkoetter> btw in regard of edubuntu, I found out a VERY simple solution to save ram on the server side by disabling X altogether. I mean an easy opportunity to set it up
[14:08] <rhorstkoetter> you just need (thanks to upstart > 1.3) to setup /etc/init/lightdm.override with "manual" in there
[14:09] <rhorstkoetter> most likely you know that but I'd say this would be something for docu at edubuntu
[14:09] <highvoltage> rhorstkoetter: indeed, we're in dire need of some "tips and tricks" documentation
[14:09] <rhorstkoetter> if you then want to get X back just "sudo mv lightdm.override lightdm.override_
[14:09] <highvoltage> how much ram does that save, btw?
[14:09] <rhorstkoetter> 100mb
[14:10] <rhorstkoetter> approx
[14:10] <rhorstkoetter> I currently have around 50mb ram usage (htop) after a fresh boot
[14:10] <rhorstkoetter> and that's pretty slick
[14:11] <rhorstkoetter> I also disabled network-manager
[14:11] <rhorstkoetter> so by disabling that one and X I got down to around 50 megs
[14:12] <rhorstkoetter> next thing will be to experiment with zram
[14:13] <rhorstkoetter> I feel that as a good approach to deal with memory peaks
[14:13] <rhorstkoetter> assumed you have a fast processor
[14:13] <ogra_> just install the zram-conf package in your chroot
[14:13] <rhorstkoetter> in chroot?
[14:13] <ogra_> even works nocely on slow processors
[14:13] <ogra_> well, if you want zram on the client, do it in the chroot, yes
[14:13] <highvoltage> hmm, I haven't tried zram on an ltsp application server before
[14:13] <alkisg> rhorstkoetter: does your server have so little ram that saving 50mb is worth the trouble?
[14:13] <rhorstkoetter> I would have installed it at the server fs
[14:14] <rhorstkoetter> alkisg: this is just a test server with 1gb ram
[14:14] <alkisg> You supposedly need about 256 mb ram per client...
[14:14] <rhorstkoetter> alkisg: and there is not much trouble involved but editing 3 text files
[14:15] <alkisg> You could just pass "text" in grub
[14:15] <rhorstkoetter> I think 50 megs worth of memory is 50 megs worth of memory even with a quad core and 8gb ram, isn't it?
[14:15] <alkisg> I spent an afternoon to save 0.5 mb ram per thin client (the openvt memory)
[14:15] <alkisg> ...but no, for the server, I wouldn't bother for 50mb
[14:15] <rhorstkoetter> alkisg: true, that would be another opportunity for X
[14:16] <rhorstkoetter> the override thing also is just one file edit though
[14:16] <alkisg> I mean, for a real server with enough ram
[14:16] <rhorstkoetter> I'd be more interested in getting rid of plymouth without uninstalling it
[14:16] <highvoltage> rhorstkoetter: I tend to agree with you that 50MB of RAM is always worth saving
[14:16] <rhorstkoetter> seems to be controlled by upstart as well
[14:16] <ogra_> you cant
[14:17] <highvoltage> plymouth is essential in ubuntu, but you can disable the actual graphical splash it shows, at least
[14:17] <rhorstkoetter> ogra_: plymouth?
[14:17] <ogra_> there are plenty bits that at least need libplymouth
[14:17] <rhorstkoetter> ogra_: have you tried to disable the upstart job yet?
[14:17] <rhorstkoetter> just curious
[14:17] <ogra_> yes
[14:17] <rhorstkoetter> and? what happens?
[14:17] <ogra_> you can disable it, but you cant remove it
[14:18] <rhorstkoetter> I wouldn't want to remove it, just disable it
[14:18] <rhorstkoetter> to save ram
[14:18] <ogra_> else your initrd mountall process would commit suicide, it needs libplymouth for communicastion
[14:18] <rhorstkoetter> but plainly disabling it should be no matter or? I mean libplymouth still is on hdd that way
[14:19] <ogra_> it wont save any ram though
[14:19] <rhorstkoetter> ok, I see
[14:19] <ogra_> plymouth kills itself right after boot (before switching to X)
[14:19] <ogra_> (or before enabling ttys, depends how you look at it)
[14:19] <rhorstkoetter> I guess I'm too ambitious to put as much <service>.overrides in /etc/init as possible
[14:20] <rhorstkoetter> lol, seems my new hobby
[14:20] <alkisg> You can remove plymouth from the initramfs but as ogra says it doesn't matter after the initial boot, it's only worth it for 64mb ram clients which can't boot otherwise
[14:20] <rhorstkoetter> alkisg: I see, thx for sharing experiences
[14:20] <alkisg> rhorstkoetter: there's an RM_SYSTEM_SERVICES lts.conf variable
[14:20] <ogra_> yeah, if you need a minimal initrd you should divert the initrd scripts and hooks actually
[14:20] <alkisg> Please do send your comments about additional services needed to be enabled/disabled there
[14:21] <rhorstkoetter> alkisg: lol, you know what? you seem to me like being lts.conf expert top notch
[14:21] <alkisg> All the persons you're talking to now are ltsp devs ;)
[14:21] <ogra_> given that he is one of the current core programmers of LTSP it would be scary if he didnt
[14:23] <rhorstkoetter> that's correct and I appreciate your companion
[14:24] <rhorstkoetter> btw, as I'm talking to ltsp devs. is someone of you using another linux distro for these kind of setups than ubuntu?
[14:24] <rhorstkoetter> just curious
[14:25] <ogra_> well, thats an odd thing to ask in the edubuntu channel ... what answers would you expect ? :)
[14:25]  * highvoltage occasionally does some testing for debian-edu, but doesn't use it in any day-to-day scenearios
[14:26] <ogra_> if you want other distros, try #ltsp ... there you will also find gentoo, fedora and debian
[14:26] <rhorstkoetter> ogra_: right, we're in edubuntu. anyways, I'd expect an honest one
[14:26] <ogra_> and that ltsp fork that opensuse uses
[14:27] <rhorstkoetter> I myself would never use anything else but ubuntu (always did, despite my opensuse cloak :p)
[14:27] <rhorstkoetter> occasionally use archlinux as I like the tinkering
[14:27] <highvoltage> I don't get any more money or credit of any kind no matter what you use, so I like to think that my answers isn't particularly biased :)
[14:27] <highvoltage> s/isn't/aren't/g (aparently I can't do english today)
[14:28] <rhorstkoetter> ogra_: I do not want to use something else myself. ubuntu works for me and always did
[14:28] <ogra_> i didnt assume you wanted :)
[14:28] <ogra_> but to get a more representative overview #ltsp is surely better
[14:29] <rhorstkoetter> no need for it actually. just chitchatting a bit out of curiousity
[14:29] <highvoltage> ogra_: btw, are you feeling better?
[14:30] <rhorstkoetter> highvoltage: most likely your english is better than or ogra_'s or mine. should be at least
[14:30] <highvoltage> stgraber: ubiquity seems to work fine for today's image, at least :)
[14:31] <rhorstkoetter> alkisg: btw, as a follow-up to our discussions yesterday, my graphics problems/artefacts gone away once I switched back to gtk based DEs. they only occured in both KDE and razorqt
[14:33] <rhorstkoetter> haven't tried the lts.conf variable though as I anyway decided to provide a GTK based DE to the pupils and as these worked (LXDE, Xfce, Gnome, Unity) there wasn't any need for tweaking anymore
[14:33] <alkisg> rhorstkoetter: did you try X_SMART_COLOR_DEPTH?
[14:33] <alkisg> ok
[14:33] <rhorstkoetter> nope. it's in my cheat sheet though
[14:35] <rhorstkoetter> in case I have another steak of madness to give KDE a try (happens once a year approximately and lasts an hour usually) :p
[14:35] <ogra_> highvoltage, yeah, since a wekk already
[14:35] <highvoltage> ogra_: great
[14:35] <rhorstkoetter> s/steak/streak
[14:37] <rhorstkoetter> as I'm dealing with ltsp devs here. reading (in parallel) about etherboot, it seems that it's now called gpxe and then ipxe
[14:37] <rhorstkoetter> is this correct
[14:37] <rhorstkoetter> ?
[14:41] <highvoltage> rhorstkoetter: yep
[14:41] <highvoltage> stgraber: so, I guess since stellarium is highly unlikely to run well on arm, we should probably just drop it for kstars?
[14:46] <stgraber> highvoltage: I guess so, I dropped it yesterday anyway
[14:46] <highvoltage> stgraber: ah, cool
[14:47] <rhorstkoetter> highvoltage: ok, thx. I guess I need to read the ipxe docu now as the sis900 isn't booting neither from internal bootrom nor from ipxe live cd (i.e. just let it boot without any config)
[14:47] <rhorstkoetter> hope I get this settled as atheros bootrom works just fine
[14:47] <rhorstkoetter> just the sis900 seems to be a major pita
[14:48] <highvoltage> stgraber: I see the gnote task is marked as complete, does that mean that tomboy notes are migrated?
[14:48] <stgraber> no idea, but we didn't ship tomboy in 12.04 so I don't really care :)
[14:48] <stgraber> I just added gnote to the seed
[14:48] <highvoltage> stgraber: yeah, I was thinking something along the same lines
=== jbicha is now known as Guest70781
[14:55] <highvoltage> gnote doesn't seem to add a menu in gnome fallback session
[14:56] <highvoltage> (as in, a panel menu or indicator or whatever you call it these days)
[14:56]  * highvoltage checks under unity
[14:57]  * ogra_ calls it "thing"
[14:58] <ogra_> thats never wrong :)
[14:58] <highvoltage> hehe
[14:59] <highvoltage> hmm, only way to seem to access it is by pressing alt+f12. perhaps Guest70781 will have some more insight on what we could do there
[15:03] <highvoltage> the gnote applet works in gnome-fallback. not sure how to add it in unity though
[15:03] <highvoltage> it crashes though :-/

[15:14] <highvoltage> ooh, gimp 2.8 has landed in quantal
[15:32] <highvoltage> stgraber: is xdiagnose something we should have in the menus? (it's under accessories currently)
[15:33] <rhorstkoetter> hi again
[15:34] <rhorstkoetter> have you ever dealed with the sis900 nic before. I think I remember highvoltage said something earlier
[15:35] <rhorstkoetter> problem is that this card is driving me crazy and I hope you have some ideas still. plugging in the very same cable to my netbook (atheros pxe) works perfect
[15:35] <stgraber> highvoltage: I see it in Ubuntu too, so if it shouldn't be there, it should be changed in the package itself, not in Edubuntu
[15:35] <rhorstkoetter> sis900 doesn't even receive an ip address via dhcp
[15:36] <rhorstkoetter> tried with builtin bootrom and now with ipxe boot disc with the very same result
[15:36] <rhorstkoetter> no dhcp
[15:36] <rhorstkoetter> have you ever encountered some issue like that .. at best with sis900 nic? google isn't that helpful either
[15:37] <rhorstkoetter> unfortunately
[15:38] <rhorstkoetter> the cabling and dhcp setup is perfectly correct. I plug the cable out of sis900 nic and into the netbook and it boots right away
[15:38] <rhorstkoetter> plugging it back to sis nightmare and neither builtin bootrom nor ipxe is able to get dhcp
[15:39] <rhorstkoetter> I even tried to configure static ip via ipxe and I cannot even ping from dhcp server/edubuntu
[15:40] <rhorstkoetter> while ipxe properly recognizes sis900 it doesn't seem to work at all and I'm curious if some of you came across that very issue already sometimes in the past
[15:51] <stgraber> highvoltage: saw you -artwork upload, are you overriding both /ubuntu and /gnome-classic now or just /gnome-classic (the later would be wrong I think)
[16:11] <highvoltage> stgraber: both
[16:11] <stgraber> good
[16:11] <highvoltage> (since I guess we don't want to see them un unity either)
[16:11] <stgraber> right
[16:12] <highvoltage> stgraber: I told the guys in #kubuntu-dev about it too...
[16:12] <highvoltage> (I'll probably file a bug for it because they were like "oh yeah, that", but didn't particularly seem to care about fixing it atm)
[16:14] <stgraber> highvoltage: or just change it and propose the branch for merging, that way a patch pilot will merge it and the kde folks will just have to deal with it ;)
[16:41] <highvoltage> stgraber: hmm, every time we make an artwork change we have to download the whole wallpapers binary package too
[16:41] <highvoltage> stgraber: is there a way to have its version seperate? what was the rationale again for moving it to the edubuntu-artwork meta-package?
[16:42] <highvoltage> source package, even
[16:52] <highvoltage> stgraber: I see there's a comment file for the northern lights wallpaper. where is it displayed in the UI? It seems kind of an awesome way to teach people things via wallpapers
[16:55] <stgraber> highvoltage: no idea :)
[16:56] <stgraber> highvoltage: I can't remember the reason to merge -wallpapers in -artwork, could have been related to the gconf/dconf schema and the rest of the integration being in that source
[17:47] <highvoltage> mgariepy: I took a stab at a menueditor icon
[17:47] <highvoltage> mgariepy: any ideas or objections? http://people.ubuntu.com/~jonathan/files/quantal/edubuntu/icons/menueditor.svg
[17:48] <highvoltage> (still making some small tweaks for alignment, etc)
[17:51] <mgariepy> highvoltage, cool :)
[17:51] <mgariepy> it looks very nice :)
[17:52] <rhorstkoetter> I guess I need some help still with for me very curious network issues
[17:52] <rhorstkoetter> do you people have some spare time to help again please?
[17:52] <highvoltage> (or a png: http://people.ubuntu.com/~jonathan/files/quantal/edubuntu/icons/menueditor2.png)
[17:52] <rhorstkoetter> I try to explain ...
[17:53] <rhorstkoetter> the ltsp server has two interfaces (sis900 and rtl8139) sis900 to the outside, rtl8139 to the inside
[17:54] <rhorstkoetter> the only client that's able to boot is an n450 netbook with atheros ethernet (not sure about the exact chipset)
[17:54] <rhorstkoetter> two other client (sis900 and a thinkpad r32) won't boot
[17:55] <rhorstkoetter> I tried for hours reading about lots of pxe issues booting from sis900
[17:55] <rhorstkoetter> then I tried the thinkpad just to see that it won't boot either
[17:55] <rhorstkoetter> then ...
[17:55] <highvoltage> have you tried booting from a gpxe iso?
[17:56] <rhorstkoetter> yes.
[17:56] <rhorstkoetter> etherboot, gpxe, ipxe
[17:56] <rhorstkoetter> all won't boot
[17:56] <highvoltage> what do they say?
[17:56] <rhorstkoetter> then I got suspicious against the server (rtl8139)
[17:56] <rhorstkoetter> dhcp timeout
[17:56] <highvoltage> mgariepy: should I change it in the package too? I think it looks good in the menus (tested it in a VM)
[17:56] <rhorstkoetter> highvoltage: now it comes ;)
[17:57] <rhorstkoetter> thinkpad said no cable connected when booting
[17:57] <rhorstkoetter> and trust me the cable was on there
[17:57] <rhorstkoetter> in fact the very same successfully booting the netbook 10 times in a row
[17:58] <rhorstkoetter> I got to the conclusion that it's neither the sis900 client nor the thinkpad failing but the rtl8139 on the server side
[17:58] <rhorstkoetter> I thus switched the interfaces: sis900 to the inside this time, rtl8139 to the outside
[17:59] <rhorstkoetter> please don't be confused … server also has ONE sis900
[17:59] <rhorstkoetter> and guess what? netbook boots, sis900 client does not, neither does the thinkpad - on the very same cable with the very same error
[18:00] <rhorstkoetter> I almost got to the conclusion to be too silly to plug in ethernet but I triple checked and the cable definately works on netbook
[18:01] <rhorstkoetter> my gosh … this doesn't seem to come to an end
[18:01] <rhorstkoetter> so, long story short (sorry but it gets more complex by the hour)
[18:02] <rhorstkoetter> my current conclusion is that the netbook somehow "tells" the server (sis900 + rtl8139) that it is actually connected
[18:02] <rhorstkoetter> I know this sounds crazy but I have no other explanation why the netbook boots in all configurations while the thinkpad and the sis900 client refuse to boot
[18:03] <rhorstkoetter> what do you think? any recommendations?
[18:03] <rhorstkoetter> I mean my very own network knowledge came (almost) to an end
[18:03] <rhorstkoetter> thanks in advance
[18:59] <highvoltage> anyone around for an edubuntu meeting?
[19:00]  * highvoltage heads over to #ubuntu-meeting
[19:01] <stgraber> kinda
[19:01] <highvoltage> good enough :)
[19:18]  * highvoltage just gave a quick summary anyway
[20:30] <highvoltage> oash. we still have geogebra on the slideshow
[21:11] <d1zzYLuLz> so, as a school project we tried to start a charity (www.connectingourfuture.org)  we're going to put edubuntu on some old systems to donate to local daycares
[21:11] <d1zzYLuLz> i'd like to use xfce or lxde, somethign lightweight...do you think it'd be easier to use xubuntu + edubuntu repos or edubuntu and install xfce?
[21:14] <alkisg> d1zzYLuLz: how old systems? How much RAM?
[21:15] <alkisg> If they're very old, you might want to consider LTSP, i.e. use them as thin clients instead
[21:16] <d1zzYLuLz> they're pretty old..im goin to max out there ram
[21:16] <d1zzYLuLz> LTSP though, it's not much
[21:16] <d1zzYLuLz> it's like 2 computers here, 3-4 there...
[21:16] <alkisg> Ah, ok. So you think about 512 ram?
[21:16] <d1zzYLuLz> otherwise, the whole project was a pretty bad flop
[21:17] <d1zzYLuLz> yeah maybe a little more than that..def no more than 2GB in the best one
[21:17] <alkisg> With 1-2 Gb you could just install edubuntu, no need for lxde/xfce
[21:17] <d1zzYLuLz> but im guessing between 512-1gb
[21:17] <alkisg> For that ^ yeah something lighter would probably be better
[21:17] <d1zzYLuLz> and use the gnome fallback?
[21:17] <alkisg> Yeah, it's easier for older PCs
[21:18] <alkisg> For 512 I'd use LXDE, for 1 Gb, gnome-fallback
[21:18] <alkisg> So if you're going to have 512 mb clients, maybe go with lxde for all of them...
[21:18] <d1zzYLuLz> okay...so do you think lubuntu w/ edubuntu repos, or edubuntu and install lxde
[21:19] <alkisg> For 512, the first
[21:19] <alkisg> E.g. some might only want gtk apps to avoid the kde libs
[21:19] <alkisg> That would save them lots of ram
[21:20] <alkisg> (btw there are no "edubuntu repos", it's just main/universe etc)
[21:20] <d1zzYLuLz> oh, okay..i thought their were special edubuntu repos..
[21:20] <d1zzYLuLz> so i'll have to find a list of good games
[21:31] <v4169sgr> Hello, I have a question about Dell FX170 thin clients and LTSP
[21:31] <v4169sgr> Is this the right place to ask?
