| 10:33 | <hipy> can i connect to ltsp via a pc already runnin g with an os
| |
| 10:37 | <johnny> if you want the full experience, you'd need to run a virtual machine.. otherwise you could connect via vnc or remote X
| |
| 10:38 | from a windows pc.. it is probably easier to use vnc..
| |
| 10:38 | from linux, you can try both
| |
| 10:46 | <vagrantc> hipy: you can connect to an LTSP server through a variety of protocols, as LTSP is largely just a collection of services to network boot and run remote sessions.
| |
| 10:46 | but then you're not using LTSP. it's just remote X or VNC or whatever at that point.

| 11:05 | <alkisg> vagrantc: I saw in the initramfs-tools/scripts/nfs that it calls modprobe af_packet, and I tried to replace the `sleep`s in udhcpc with that, and it worked fine. Do you think that's a better method?
| |
| 11:06 | <vagrantc> alkisg: no idea
| |
| 11:07 | <alkisg> Hmmm I'll mail the devel list with the patch, and I hope someone will know more than us! :-/ Thanks, though...
| |
| 11:09 | <elias_a> Hello!

| 12:30 | pikudoz4 has quit IRC | |
| 12:34 | pikudoz has quit IRC | |
| 12:35 | <vagrantc> alkisg: i think af_packet is needed to do dhcp type requests
| |
| 12:35 | alkisg: but it may not neccesarily be a module
| |
| 12:36 | <alkisg> "not neccesarily be a module" ==> sorry I didn't get this
| |
| 12:36 | <vagrantc> alkisg: "modprobe af_packet" ... that loads modules ... i think it tends to be compiled into the kernel, at least on debian.
| |
| 12:37 | but on older kernels, it wasn't
| |
| 12:37 | pikudoz1 has quit IRC | |
| 12:37 | <alkisg> I wonder why it would work with that and without `sleep`, then...
| |
| 12:38 | <vagrantc> alkisg: you run the udhcp stuff way earlier in the process than configure_networking is normally called
| |
| 12:38 | alkisg: maybe you're running it too early?
| |
| 12:38 | <alkisg> Yes, that was not my desicion - stgraber put it there so that he didn't have to change any other initscripts
| |
| 12:39 | I'd also prefer it if it could be called instead of configure_networking
| |
| 12:39 | <vagrantc> still would be interesting to see if you could override the configure_networking function, and then it would "just work" with all the other scripts.
| |
| 12:39 | <alkisg> I don't think so, because the scripts are exec'ed, not sourced...
| |
| 12:40 | <vagrantc> well, you can turn them into something source-able.
| |
| 12:40 | it would require some re-writing, but that would seem a better way to integrate.
| |
| 12:40 | <alkisg> How would I do that, without modifying init?
| |
| 12:40 | pikudoz2 has quit IRC | |
| 12:41 | <alkisg> ...unless I exported a whole function in the "return file" -- each initscript generates a file with variables to be returned, maybe I could misuse it to return a configure_networking function... :-/
| |
| 12:42 | Nah, that wouldn't work either
| |
| 12:47 | vagrantc, on another front, I'm trying to create a proper <chroot>/etc/ltsp/update-kernels.conf so that <chroot>/usr/share/ltsp/update-kernels would generate a pxelinux.cfg/default with a *menu* in it. I don't think I can do it with the currently supported variables... Could I try to come up with some suggestions on that?
| |
| 12:48 | ...or, if a $PXELINUX_PREPEND_FILE was also defined, instead of hardcoding Default ltsp, I think that would also work.
| |
| 12:50 | <johnny> i don't even use configure_networking in gentoo
| |
| 12:50 | i just rely on the actual init scripts
| |
| 12:51 | i hope to eventually be able to rely on the init scripts only..
| |
| 12:51 | with a few *hints* or whatever
| |
| 12:51 | <alkisg> How different are the (non-ltsp) initscripts of gentoo, compared to ubuntu?
| |
| 12:51 | * alkisg has never seen init scrips from other distros | |
| 12:52 | <johnny> much better
| |
| 12:53 | much much much better..
| |
| 12:53 | <alkisg> Heh :)
| |
| 12:53 | <johnny> altho perhaps not better than native upstart scripts
| |
| 12:53 | which aren't really used yet.
| |
| 12:53 | but they are much better than the compat style used up to this point
| |
| 12:54 | alkisg, they are dependency based.. so none of the rc*.d/ files
| |
| 12:54 | and you can set up profiles
| |
| 12:54 | like nonetwork
| |
| 12:55 | <alkisg> I think ltsp can be booted with the "non-ltsp" ubuntu initscripts, i.e. without using the ltsp modifications. Lts.conf won't be downloaded from tftp, but other than that I think it boots...
| |
| 12:55 | <johnny> shouldn't it be? that is done in the initramfs on ubuntu iirc
| |
| 12:55 | now.. on fedora and gentoo.. they wouldn't be
| |
| 12:56 | <alkisg> Yeah I mean that not much modifications are needed in the default ubuntu initramfs to be able to boot ltsp
| |
| 12:56 | <johnny> no.. not the initramfs.. i'm just takling about the regular init system :)
| |
| 12:56 | <alkisg> so... will all that be replaced with dracut in the future?
| |
| 12:57 | <johnny> i don't think ltsp will boot in any kind of decent way on ubuntu without the proper init scripts disabled.. as ltsp-setup overrides much of their functionaliyt
| |
| 12:57 | i dont' do as much with that on gentoo
| |
| 12:57 | i use less of the configure_* functions and let the actual init scripts do the work..
| |
| 12:58 | alkisg, init scirpts in gentoo and both provide functionality to override defaults and depend on other init scripts.. it's not based on sequential numbering
| |
| 12:58 | the K* and S* scripts in /etc/rc?.d that is
| |
| 12:59 | <alkisg> OK I used the wrong terminology before, now I get what you mean. I was refering to the initramfs scripts as "init scripts"
| |
| 13:00 | <johnny> i plan on using dracut on gentoo for the initramfs
| |
| 13:00 | i just wish the gentoo project on the whole would adopt dracut instead of the genkernel initramfs creator..
| |
| 13:01 | <alkisg> Is it ready for adoption yet? Or is it too early?
| |
| 13:02 | <johnny> for what to adopt what?
| |
| 13:02 | <alkisg> Dracut, to be adopted e.g. in gentoo
| |
| 13:02 | Is it ready, or does it lack necessary functions?
| |
| 13:02 | <johnny> dracut is already used in fedora 12
| |
| 13:02 | <alkisg> Ooooh :) /me googles...
| |
| 13:03 | <johnny> i'm using fedora 12 alpha right now
| |
| 13:03 | it needs a few modifications to work properly in gentoo, but some are are already done
| |
| 13:05 | <alkisg> "With Dracut, the initramfs has one purpose in life - getting the rootfs mounted so that we can transition to the real rootfs." - nice, sounds focused :)
| |
| 13:06 | <johnny> alkisg, if only it was that easy :)
| |
| 13:07 | alkisg, it has stuff for nfs, nbd, fibrechannel, iscsi, aoe, etc..
| |
| 13:07 | <alkisg> aoe, lvm, iscsi, nbd... yeah I understand :)
| |
| 13:07 | <johnny> i wanna find a way to make it not try to unlock mounted /home until gdm
| |
| 13:07 | my /home is encrypted
| |
| 13:08 | i'd like to find a way to delay the unencryption until i try to login
| |
| 13:08 | perhaps i need to encrypt /home/johnny and not /home
| |
| 13:09 | <alkisg> I think I lost you there. Dracut bothers to unencrypt your /home? Isn't that an init script task?
| |
| 13:09 | <johnny> if your root is encrypted.. you must do it there
| |
| 13:09 | <alkisg> I understand the need to unencrypt /, but why /home?
| |
| 13:10 | <johnny> probably overzealous regex or something
| |
| 13:10 | <alkisg> Dah :)
| |
| 13:10 | <johnny> plus stuff like /usr might need to be done there
| |
| 13:10 | i think it might require too much special casing
| |
| 13:11 | <alkisg> It does sound like it could be something cross-distro, though, so it would have much people for testing it
| |
| 13:12 | <johnny> well.. it would be nice if somebody other than fedora adopted it :)
| |
| 13:12 | in gentoo.. it is just another option.. as we don't really have a default other than genkernel.. which many people don't even use
| |
| 13:16 | <alkisg> I saw warren is in the dracut, and I followed the link to his cv... "founded the original Fedora Project" ??? Wow!!!
| |
| 13:16 | *team
| |
| 13:19 | <johnny> yes
| |
| 13:19 | he sure did
| |
| 13:19 | warren is everywhere
| |
| 13:24 | * alkisg just saw that the netbooks to be offered to all 12 y.o. Greek students are actually dual boot (windows/edubuntu 9.04)! Woot! | |
| 13:25 | <johnny> alkisg i'm still waiting for arm netbook..
| |
| 13:25 | gimme a netbook with no optical drive and an arm chip :)
| |
| 13:25 | and ssd
| |
| 13:25 | i know tvs are starting to come out that are LED not LCD
| |
| 13:26 | i wonder what the power usage of an led display would be
| |
| 13:26 | hipy has quit IRC | |
| 13:26 | <alkisg> johnny makes alkisg google too much :-/
| |
| 13:26 | * alkisg looks for LED Tvs... :P :D | |
| 13:27 | <johnny> the only selling point on the commercial is "deeper blacks" and being THX certified
| |
| 13:27 | <vagrantc> alkisg: PXELINUX_DEFAULT=menu
| |
| 13:27 | alkisg: will default to a menu
| |
| 13:27 | alkisg: you could also use vesamenu
| |
| 13:28 | * alkisg tries... | |
| 13:32 | * vagrantc hasn't been able to update dracut git repo in a while | |
| 13:32 | <johnny> vagrantc, re clone
| |
| 13:32 | after that it worked for me
| |
| 13:32 | <vagrantc> awesome.
| |
| 13:32 | pfft.
| |
| 13:33 | johnny: same problem.
| |

| 13:33 | <vagrantc> johnny: what git URL you using?
| |
| 13:34 | <johnny> git://dracut.git.sourceforge.net/gitroot/dracut/dracut
| |
| 13:35 | bobby_C has joined #ltsp | |
| 13:35 | <johnny> too many dracuts in there..
| |
| 13:36 | <vagrantc> that seems better.
| |
| 13:36 | the /topic of #dracut still has the old location
| |
| 13:37 | <alkisg> vagrantc: Works like a charm!!! :P :D Merci!!!! (I thought that it wouldn't accept the TITLE at the end of the file, but it does)
| |
| 13:40 | <petre> In the chroot, root's $HOME is set to /root in /etc/passwd; but $HOME isn't set for the root that's on the client console (Ctrl-Alt-F2); why is that?
| |
| 13:41 | <alkisg> petre: did you login, or just used SCREEN_02=shell ?
| |
| 13:41 | <petre> alkisg, SCREEN_02=shell
| |
| 13:41 | <alkisg> petre: I think that bypasses the normal login process, so /etc/profile isn't sourced, and other things like HOME aren't set...

| |
| 15:44 | for scientific research
| |
| 15:48 | <alkisg> Pulga: the only scientific paper *I*'ve seen concerning ltsp is an environmental analysis: http://it.umsicht.fraunhofer.de/TCecology/docs/TCecology2008_en.pdf
| |
| 15:52 | <Pulga> ok
