| yeipi | sbalneav: I don't understand (my english is not good) but thinstation is a distribution forthin clients? I mean it doesn't use a server? | 08:37 |
| sbalneav | Yeah, it needs a server. | 08:38 |
| sbalneav | You install it on a server | 08:38 |
| yeipi | but | 08:38 |
| yeipi | hmmm | 08:38 |
| yeipi | does the live cd of thinstation include firefox abd X? | 08:38 |
| yeipi | and X? | 08:39 |
| yeipi | it's just too small, just 11 mb | 08:39 |
| yeipi | :/ that's my doubt | 08:39 |
| sbalneav | No, it uses the stuff up on the server. | 08:40 |
| sbalneav | I don't know much about it, since I don't use it. | 08:40 |
| yeipi | it's a like a software, so I probable could run it on any distribution... ? | 08:42 |
| sbalneav | I guess. | 08:42 |
| sbalneav | Try it and see, one supposes | 08:42 |
| sbalneav | They have their own irc channel | 08:42 |
| yeipi | ok sbalneav | 08:42 |
| sbalneav | probably better to ask there. | 08:42 |
| yeipi | yeah I think that too.:) thanks for the tip. | 08:43 |
| yeipi | sbalneav: will you release the version of ldm you're adding autologin feature? | 09:00 |

| yeipi | hi guys. is there a way to get a 16 mb client running with edubuntu?? I mean recompile the kernel, or I don't know... | 09:56 |
| yeipi | we can't get more ram for the clients | 09:56 |
| yeipi | I tried these clients with 32 mb ram and the run flawlessly, but with 16 I get a kernel panic :/ | 09:57 |
| sbalneav | stgraber: Yep | 09:59 |
| sbalneav | yeipi: 16's a little low. | 09:59 |
| === stgraber hugs sbalneav | ||
| LaserJock | sbalneav: heah dude | 10:01 |
| yeipi | sbalneav: I know but, what do you recommend to me (apart from the memory upgrade)? | 10:04 |

| === blue-frog [n=bluefrog@dyn-83-153-163-134.ppp.tiscali.fr] has joined #edubuntu | ||
| sbalneav | About the only thing we may be able to do is move the nbd swap earlier | 10:10 |
| sbalneav | How far along does it get before it dies? | 10:10 |
| sbalneav | Does it die right after loading the kernel? | 10:11 |
| sbalneav | LaserJock: heyo! | 10:11 |
| sbalneav | with 16 megs of ram, though performance is gonna be aweful. | 10:11 |
| sbalneav | Even on the old ltsp 4.2, 16 megs was too small. | 10:11 |
| yeipi_ | noo | 10:17 |
| yeipi_ | I tried k12ltsp with 16 mb ram (ltsp 4.2) and the performance is pretty acceptable | 10:18 |
| sbalneav | Which version? An old one? | 10:30 |
| sbalneav | I think the last version of LTSP we had that ran ok in 16 megs was, like, 4.1 | 10:30 |
| === Burgundavia [i=corey@ubuntu/member/burgundavia] has joined #edubuntu | ||
| sbalneav | yeipi_: You haven't told me where it dies yet? | 10:42 |
| sbalneav | Have you tried gutsy at all? We've re-written some parts that used to be in Python, and they're now written in C. | 10:43 |
| sbalneav | That may help some. | 10:43 |
| yeipi_ | hm!! | 10:43 |
| yeipi_ | ok! dude thank you! | 10:43 |
| yeipi_ | I'm gonna try gutsy | 10:44 |
| sbalneav | I guess the question is: is it dying in the initramfs, or later in the boot? | 10:44 |
| sbalneav | If it's dying in the initramfs, then that's gonna be tough to solve. | 10:44 |
| yeipi_ | and I can't say you where it hangs up 'cause I erased the partition where I had edubuntu | 10:44 |
| sbalneav | If it's dying LATER, then we may be able to solve that by either moving the nbd swap earlier in the boot process, or right into the initramfs. | 10:45 |
| sbalneav | Gonna be kinda hard for me to help you when you don't have a running edubuntu :) | 10:45 |
| yeipi_ | ok sbalneav I'm going to start using edubuntu right now dude! | 10:46 |
| yeipi_ | wait a moment please! | 10:46 |
| yeipi_ | I'm using other edubuntu server we ha | 10:47 |
| yeipi_ | I forgot we had :P | 10:47 |
| === yeipi_ is at school right now :) | ||
| sbalneav | Hmmm. | 10:48 |
| sbalneav | So, here's an interesting one. | 10:48 |
| yeipi_ | sbalneav: I tried it! | 10:48 |
| yeipi_ | and it hangs up after intramfs | 10:48 |
| sbalneav | ok | 10:48 |
| sbalneav | so lets do this. | 10:49 |
| sbalneav | sudo chroot /opt/ltsp/i386 | 10:49 |
| sbalneav | you should then be in the choot | 10:49 |
| sbalneav | lets cd /etc/rc2.d | 10:49 |
| sbalneav | can you do an ls, and paste that to the pastebin? | 10:50 |
| yeipi_ | ok, I'm going to to it right now | 10:50 |
| sbalneav | !pastebin | 10:50 |
| ubotu | pastebin is a service to post large texts so you don't flood the channel. The Ubuntu pastebin is at http://paste.ubuntu-nl.org (make sure you give us the URL for your paste - see also the #ubuntu channel topic) | 10:50 |
| yeipi_ | ok dude | 10:50 |
| yeipi_ | http://paste.ubuntu-nl.org/31455 | 10:53 |
| yeipi_ | I already did it dude | 10:53 |
| sbalneav | k | 10:57 |
| sbalneav | ok | 10:57 |
| sbalneav | lets see what we can do here.... | 10:58 |
| yeipi_ | ok sbalneav :) | 10:59 |
| sbalneav | alright, not sure if this will work, but... | 11:00 |
| sbalneav | you're in the chroot, so... | 11:00 |
| sbalneav | rm S20nbd-client | 11:00 |
| sbalneav | ln -s S19nbd-client ../init.d/nbd-client | 11:00 |
| sbalneav | That will put the nbd-client BEFORE the ltsp startup | 11:00 |
| yeipi_ | ok dude lemme do it | 11:01 |
| sbalneav | so now, when you so an ls, S19nbd-client should execute before S20ltsp | 11:02 |
| yeipi_ | I got an error: '../nit.d/bnd-client' to 'S19nbd-client' : file exits | 11:03 |
| yeipi_ | exists | 11:03 |
| yeipi_ | is the ln -s well done? | 11:03 |
| yeipi_ | ln -s origin destiny | 11:03 |
| === Burgundavia_ [i=corey@ubuntu/member/burgundavia] has joined #edubuntu | ||
| yeipi_ | ln -s ../init.d/nbd-client S19nbd-client ? | 11:04 |
| sbalneav | oh, yeah | 11:04 |
| sbalneav | sorry | 11:04 |
| sbalneav | bass ackwards | 11:04 |
| === Burgundavia_ is now known as Burgundavia | ||
| yeipi_ | jejeje ok | 11:04 |
| yeipi_ | :P | 11:04 |
| yeipi_ | lemme do it | 11:04 |
| sbalneav | ok, so once you've got that done, try a reboot, and see if you get any farther, | 11:05 |
| yeipi_ | ok dude, I did that ln | 11:05 |
| yeipi_ | and now Im gonna reboot | 11:05 |
| yeipi_ | im gonna disconnect | 11:06 |
| yeipi_ | brb | 11:06 |
| sbalneav | k | 11:06 |
| yeipi_ | it says: unpacking intramfs | 11:10 |
| yeipi_ | and then appeared the kernel panic | 11:10 |
| yeipi_ | :( | 11:10 |
| sbalneav | ok, so it's dying right in the unpack of the initramfs | 11:12 |
| yeipi_ | yep! | 11:12 |
| sbalneav | so, basically, the initramfs needs to get smaller. | 11:12 |
| yeipi_ | how could I do it? | 11:14 |
| sbalneav | hm | 11:15 |
| sbalneav | lemme see | 11:15 |
| yeipi_ | ok :) | 11:15 |
| sbalneav | Hmm | 11:25 |
| sbalneav | There's not a lot of spare room to delete out of there. | 11:25 |
| yeipi_ | sbalneav: do you think if I increase the swap memory? | 11:26 |
| yeipi_ | :/ | 11:26 |
| sbalneav | No, because it's dying while uncompressing the initramfs | 11:27 |
| yeipi_ | ok | 11:27 |
| sbalneav | so it's never even gotten to swap. | 11:27 |
| sbalneav | About the only thing you MAY be able to do is try come up with a smaller kernel, but that's going to be hard given a 2.6 kernel series. | 11:28 |
| yeipi_ | hmm Ok dude | 11:28 |
| sbalneav | The k12ltsp was using a 2.4 kernel for the client? | 11:28 |
| yeipi_ | yep 2.4 | 11:28 |
| sbalneav | yeah | 11:28 |
| yeipi_ | you think I have to recompile the kernel? | 11:28 |
| sbalneav | How many of these 16 meg machines you got? | 11:28 |
| yeipi_ | ufff | 11:29 |
| yeipi_ | so many dude | 11:29 |
| yeipi_ | cents! | 11:29 |
| yeipi_ | a lot of schools here got these machines (with 16mb ram) | 11:29 |
| sbalneav | do you NEED them all? Any chance you could do with 1/2 the number of machines, take the ram out of one set to make one with 32 megs of ram? | 11:29 |
| sbalneav | i.e. You got a 100 16 megs, so make 50 32 megs? | 11:30 |
| yeipi_ | hmm | 11:30 |
| yeipi_ | those computers are on rural schools | 11:30 |
| yeipi_ | poor schools that got 2 o 3 of those computers | 11:30 |
| sbalneav | hm | 11:31 |
| yeipi_ | so it'll just one computer working | 11:31 |
| yeipi_ | we gave those schools the server and newer networks card and that's all we can give them :/ | 11:31 |
| yeipi_ | (sorry my enligsh dude) | 11:32 |
| sbalneav | Well, about the only thing that could be done is to come up with a custom kernel that strips out EVERYTHING that isn't needed. | 11:32 |
| sbalneav | Are all these machines "the same"? I.e. same motherboard, video card and network card? | 11:32 |
| yeipi_ | yep | 11:32 |
| yeipi_ | i.e. | 11:32 |
| yeipi_ | olivetti m24 | 11:32 |
| yeipi_ | ibm pc100 | 11:32 |
| yeipi_ | cents of those computers | 11:33 |
| yeipi_ | all of 'em with 16 mb ram | 11:33 |
| sbalneav | ok, you're going to have to find out EXACTLY what's in those computers. | 11:33 |
| sbalneav | EXACTLY what video chipset, EXACTLY what mobo chipset, etc. | 11:33 |
| yeipi_ | I know exactily | 11:33 |
| yeipi_ | yep we know | 11:33 |
| sbalneav | ok | 11:33 |
| yeipi_ | sound video modules, etc... | 11:34 |
| sbalneav | Well, best I can offer is, send me the specs to sbalneav@ltsp.org | 11:34 |
| sbalneav | I'll try and come up with a step by step guide to what you need to do to build a more scaled down kernel. | 11:34 |
| sbalneav | but there's not a lot of spare room in there to fidlle with, but maybe we can shave a meg off or so. | 11:35 |
| yeipi_ | wow dude? I really thank you that! | 11:35 |
| sbalneav | I'm not going to garantee anything. | 11:35 |
| yeipi_ | ok lemme recollect those specs | 11:35 |
| sbalneav | You could, as a stopgap measure, install an OLD version of ltsp manually under Edubuntu | 11:36 |
| yeipi_ | ok dude, I understand, but I don't lose anything trying it out | 11:36 |
| sbalneav | You won't get local devices or sound, but if that's ok, you could make that work too. | 11:36 |
| sbalneav | You can mix and match ltsp chroots, so you could have an ltsp5 chroot for "newer, better" machines, and for the old ones, use a really old ltsp4.1 chroot. | 11:37 |
| sbalneav | but maybe if we shrink the kernel down enough, we can get it to the point where we can turn on nbd swap. | 11:37 |
| sbalneav | Anyway, I gotta head home for the day. | 11:38 |
| sbalneav | mail me at sbalneav@ltsp.org, and I'll see what I can do. | 11:38 |
| sbalneav | cheers. | 11:38 |
| blue-frog | sorry to ask the question here but cannot get an answer elsewhere and I am pretty sure the answer must be "simple" | 11:50 |
