| |
| 09:16 | i am currently evaluating the possibility of using ltsp in an internetcafe / computer pool
| |
| 09:16 | do you know if disklessworkstations.com will ship to europe?

| 12:55 | <warren> Q-FUNK, I haven't got any commitments from our X team
| |
| 12:55 | Q-FUNK, they did however say that they planned on porting all X drivers except a short list of ancient hardware
| |
| 12:55 | <Q-FUNK> warren: ok
| |
| 12:57 | warren: it would be nice if you guys could contribute at least some of the remaining items, such as porting this to libpciaccess
| |
| 12:57 | <warren> Q-FUNK, that's among the list of things they said they would do
| |
| 12:57 | <Q-FUNK> warren: nice to hear. any ETA?
| |
| 12:57 | warren: any way they could manifest themselves on the xorg-geode list too?
| |
| 13:06 | J45p3r has joined #ltsp | |
| 13:20 | <warren> Q-FUNK, they are not very communicative
| |
| 13:20 | Q-FUNK, this is based upon a public announcement on fedora-devel-list
| |
| 13:20 | Q-FUNK, before fedora 9 they will be porting all x drivers except a short ancient list
| |
| 13:21 | <Q-FUNK> warren: it would be useful for them to get in touch and send me their diff.
| |
| 13:26 | <warren> Q-FUNK, you are the upstream maintainer of the driver now right?
| |
| 13:26 | <Q-FUNK> yup
| |
| 13:26 | of -amd

| |
| 14:40 | <dberkholz> ahh yes
| |
| 14:41 | mainly because i've been trying to track down arjan for a week or so
| |

| 15:35 | Furlow has joined #ltsp | |
| 15:39 | <Furlow> Hi all I need help with ltsp my current sittuation is that I mean running my server with one nic and i have booted using pxe on my laptop, I have a login window but I can't login. I type the user and then the password (both are correct) and I get the "verifying password, please wait" message it then goes to a blank screen and then the login re appears. On my switch none of light flicker when I login which would make me guess
| |
| 15:41 | <vagrantc> Furlow: which linux distro?
| |
| 15:41 | cliebow_ has quit IRC | |
| 15:44 | cliebow__ has quit IRC | |
| 15:46 | <Furlow> ubuntu
| |
| 15:46 | I have ubuntu 7.10
| |
| 15:49 | <vagrantc> Furlow: dpkg -l 'ltsp*' | egrep ^ii ; dpkg --root=/opt/ltsp/i386 -l 'ltsp*' ldm | egrep ^ii
| |
| 15:50 | Furlow: your server has a static ip address?
| |
| 15:50 | <Furlow> what will that do vagrantc???
| |
| 15:50 | yes it does
| |
| 15:50 | have a static ip
| |
| 15:50 | <vagrantc> Furlow: it will show the ltsp versions of the ltsp related packages, and which you have installed
| |
| 15:51 | Furlow: is is possible that the ip address changed since you installed ltsp ?
| |
| 15:51 | <Furlow> I just found out on a found out on a forum that they had select gnome sessions to login and that worked for me so I m just fine as it is, so now on to secondary configuration, is there some kind of xorg.conf I can create for each separate client using the mac address so that my laptop will display 1280x800 instead of a small annoying box screen with black edges
| |
| 15:51 | thank you for your help
| |
| 15:52 | also will I have to keep selecting the gnome session or will it act as default the next time i boot the client??
| |
| 15:52 | <vagrantc> Furlow: you should have an lts.conf somewhere ... /var/lib/tftpboot/ltsp/ ... youneed to add options there
| |
| 15:52 | i don't know- i don't use ubuntu
| |
| 15:53 | it should just use your default session .... /usr/sbin/update-alternatives --display x-session-manager
| |
| 15:53 | <Furlow> oh okay I will read up on the lts.conf I thought I might need to do something with that
| |
| 15:53 | okay thank you very much
| |
| 15:53 | <vagrantc> Furlow: you can specify each machine by mac address [00:a5:05:50:14]
| |
| 15:54 | Furlow: and then specify options there ... like X_CONF=/path/to/xorg.conf
| |
| 15:54 | Furlow: needs to be a full path relative to the thin-client's root ....
| |
| 15:55 | Furlow: and you'll need to run ltsp-update-image after updating your chroot ...
| |
| 15:55 | * vagrantc cringes | |
| 15:56 | <Furlow> where is my thin client root or where should it default be, or do and can I make separate roots for each client?
| |
| 15:57 | <vagrantc> whoah...
| |
| 15:57 | <Furlow> so that they all have there own personalised settings
| |
| 15:57 | did ask to much???
| |
| 15:57 | <vagrantc> 90% of the point of ltsp is to share the root environments between multiple machines
| |
| 15:57 | you thin client root is probably /opt/ltsp/i386
| |
| 15:58 | and then ubuntu does this thing where any time you modify that, you have to run ltsp-update-image and it will create a new /opt/ltsp/images/i386.img
| |
| 15:58 | <Furlow> yes it is
| |
| 15:58 | <vagrantc> which takes a long time
| |
| 15:59 | <Furlow> okay well I can go make a coffee and come back
| |
| 15:59 | <vagrantc> i guess long time is relative ...
| |
| 15:59 | but anyways ...
| |
| 15:59 | <Furlow> thanks so editing xorg.conf is just like normal
| |
| 16:00 | <vagrantc> well, /opt/ltsp/i386/etc/X11/xorg.conf get's overwritten on boot, unless you specify CONFIGURE_X=False
| |
| 16:01 | so i would recommend setting up /opt/ltsp/i386/etc/X11/xorg.conf.FOO and then specifying in lts.conf X_CONF=/etc/X11/xorg.conf.FOO ...
| |
| 16:02 | <Furlow> could I just put it in a separate folder in X11 and then specify X_CONF=/path/to/xorg.conf.......as I was typing you came similar suggestion would yours be better practise or would the setup i suggested work I don't mind which one I do just currious
| |
| 16:03 | also where is the lts.conf
| |
| 16:04 | <vagrantc> X_CONF=/path/to/xorg.conf will copy /path/to/xorg.conf to /etc/X11/xorg.conf
| |
| 16:04 | Furlow: /var/lib/tftpboot/ltsp/i386/lts.conf ... i think ... this is where ubuntu and debian start to differ a lot.
| |
| 16:05 | <Furlow> you have debian?
| |
| 16:05 | <vagrantc> yeah, i work on ltsp for debian
| |
| 16:05 | <cliebow> Furlow, if in gutsy..you "can" put an lts.conf in /var/lib./tftpboot and have it tftp downl;oaded
| |
| 16:06 | * vagrantc offers cliebow a new keyboard | |
| 16:06 | <cliebow> pardon the extra crap there
| |
| 16:06 | vagrantc, it doesnt help 8)

| 16:08 | <Furlow> I got it /opt/ltsp/i386/etc/lts.conf if anyone else needed to know where the ubuntu lts.conf is
| |
| 16:09 | RyanRyan52 has quit IRC | |
| 16:09 | <vagrantc> Furlow: read the comments in that file
| |
| 16:09 | Furlow: should tell you where to actually look.
| |
| 16:10 | <Furlow> okay that wasn't it, i must of got the wrong documentation
| |
| 16:15 | <MacIver> you can create the file
| |
| 16:15 | iirc, in edubuntu it wasn't there by default
| |
| 16:15 | bobby_C has quit IRC | |
| 16:22 | <Furlow> where do i put the lts.conf in ubuntu
| |
| 16:22 | <MacIver> Furlow: in the place /opt/ltsp/i386/etc/lts.conf told you
| |
| 16:23 | Furlow: should say in here http://scribere.no-ip.org/LTSP
| |
| 16:24 | tekteen has joined #ltsp | |
| 16:25 | <Furlow> I found my conf file finaly /opt/ltsp/i386/etc/lts.conf no for editing
| |
| 16:27 | <MacIver> /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 16:28 | <Furlow> now for editing is what i mean't say
| |
| 16:29 | <MacIver> Furlow: iirc the one in /opt/ltsp/i386/etc/lts.conf says you should use the one in /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 16:29 | <Furlow> does it let me check??
| |
| 16:29 | <MacIver> huh?
| |
| 16:29 | <Furlow> okay yeah thanks
| |
| 16:32 | i'm dyslexic (why did they make the word for the problem difficult to spell that was stupid) and so yeah i miss out the punctuation, what I meant was "does it....... Let me check"
| |
| 16:34 | <MacIver> i am dyslexic as well, but when i see the sentence i expect a certain shape to it---a break between the two thoughts
| |
| 16:38 | <Furlow> oh okay yeah although this is a dyslexic channel but anyways thought I would just say it goes under diagnosed and people generally think that it means you stupid but in fact it is the complete opposite, my real problem is mixing round all the right letters in a word just not in the right order, I'm also very forgetful not sure if that is dyslexia
| |
| 16:39 | not a dyslexia channel

| 19:35 | <Schmao-Fmao> Hey there, anyone alive at the moment?
| |
| 19:35 | I'm trying to mount the local HD on my LTSP client and I'm running into problems
| |
| 19:38 | eharrison has quit IRC | |
| 19:44 | <vagrantc> Schmao-Fmao: what linux distro?
| |
| 19:44 | <Schmao-Fmao> Ubuntu
| |
| 19:44 | <vagrantc> what release?
| |
| 19:44 | <Schmao-Fmao> Gutsy
| |
| 19:45 | I'm trying to clone systems using dd and netcat - hopefully LTSP will help me with the initial bootup
| |
| 19:45 | and then I can write a prebuilt image directly to the local hard drive
| |
| 19:45 | <vagrantc> Schmao-Fmao: so, what's the issue you're having?
| |
| 19:46 | * vagrantc wouldn't recommend netcat, as it's not very good at ensuring data integrity | |
| 19:46 | <Schmao-Fmao> I can successfully log in on the client
| |
| 19:46 | and I see the filesystem on the server
| |
| 19:47 | but I can't seem to find the device file that represents the local hard drive
| |
| 19:47 | which would normally be /dev/sda
| |
| 19:48 | <vagrantc> Schmao-Fmao: is it an IDE drive?
| |
| 19:48 | <Schmao-Fmao> I might be able to find something other than netcat - I can use systemimager, but the program package is very large, and my coworkers aren't convinced that it does exact copies
| |
| 19:48 | no, it's a SATA drive
| |
| 19:48 | Thanks for helping by the way :)
| |
| 19:49 | * vagrantc would suspect systemimager/partimage to do a much better job of ensuring exact copies | |
| 19:49 | <Schmao-Fmao> should I check out partimage?
| |
| 19:49 | <vagrantc> i think partimage is part of systemimager ...
| |
| 19:50 | <Schmao-Fmao> For SI, would I expect the golden client and the cloned machine to have filesystems that are truly exact?
| |
| 19:50 | like if I were to "diff" the contents of /dev/sda
| |
| 19:50 | would I get that there's no difference?
| |
| 19:51 | <vagrantc> can't say for sure.
| |
| 19:51 | anyways ... i'm guessing there is some kernel module or support library you need to add to your client chroot to support SATA ...
| |
| 19:52 | <Schmao-Fmao> I actually think that LTSP is a somewhat complicated solution to a simple problem - I just need to boot into *something* :)
| |
| 19:53 | I've tried to netboot an ubuntu live CD, a debian live CD, and a knoppix live CD, none of which worked completely
| |
| 19:53 | <vagrantc> i've used ltsp-like setups for cloning systems in the past. though i simply used partitioning tools and rsync ... didn't need everything to be EXACT
| |
| 19:55 | <Schmao-Fmao> That's true. I mean, if the "dmesg" is different because the MAC addresses of the network hardware are different
| |
| 19:55 | then that breaks the exactness
| |
| 19:56 | Ideally, I could get one of the live CD's to netboot properly. Do you think you can give me a few pointers for that? My questions are very specfic
| |
| 19:56 | ('cause I've been struggling with this for a while)
| |
| 19:56 | <vagrantc> not really
| |
| 19:56 | much more able to help with getting ltsp to work
| |
| 19:57 | <Schmao-Fmao> gotcha, thanks - I can keep going with that route
| |
| 19:57 | <vagrantc> i do know there's allegedly various forms of network boot for debian-live, but i mostly just lurk there, i'm not very experienced with it
| |
| 19:58 | <Schmao-Fmao> Currently, I've followed through some of the LTSP tutorials on the ubuntu wiki
| |
| 19:58 | and it seems that LTSP requires the local devices to be partitioned
| |
| 19:58 | What if they aren't partitioned?
| |
| 19:59 | I'm trying to clone onto a completely empty HD
| |
| 19:59 | <vagrantc> no, ltspfs requires the local devices to be partitioned ...
| |
| 19:59 | because it actually mounts the filesystems
| |
| 20:00 | <Schmao-Fmao> thus, I should be able to see the devices, I just can't mount them :) Got it
| |
| 20:00 | <vagrantc> but you're not able to access the device that you expect to be found at /dev/sda
| |
| 20:01 | <Schmao-Fmao> I guess here's the thing. When I go into /dev and type ls with the client
| |
| 20:01 | I seem to see exactly the same thing if I go into /dev/ and type ls on the server
| |
| 20:01 | <vagrantc> Schmao-Fmao: well, in a traditional LTSP environment, you log into a sever from the thin-client, and there's ltspfs which exports the filesystems over the network so that the server can access files on the thin-client
| |
| 20:01 | <Schmao-Fmao> About the last thing you just said
| |
| 20:01 | Do you mean "so that the thin-client can access files on the server"?
| |
| 20:02 | <vagrantc> no
| |
| 20:02 | so that the server can access files on the thin-client
| |
| 20:02 | <Schmao-Fmao> So if I have a terminal on the server
| |
| 20:02 | I should be able to see the "dev/sda" on the thin-client
| |
| 20:02 | <vagrantc> if you're logging into the server, then all the files you see are on the server.
| |
| 20:02 | no.
| |
| 20:02 | /dev/* will be the /dev/* from the server. that's the way of it.
| |
| 20:03 | brillantejcoh has joined #ltsp | |
| 20:03 | <Schmao-Fmao> oh that's not exactly what I meant
| |
| 20:03 | I mean, if I had a terminal on the server running, I should be able to access the client filesystem by going into the correct directory
| |
| 20:03 | <vagrantc> Schmao-Fmao: so, the question i have is how are you logging in? when you log in, are you logging into the thin-client itself, or using the thin-client to log into the server?
| |
| 20:03 | <Schmao-Fmao> I just need to know what that directory is
| |
| 20:03 | I'm logging into the thin-client, but once I log in I see the files on the server
| |
| 20:03 | <vagrantc> ah.
| |
| 20:04 | <Schmao-Fmao> Alternatively ... I also have a terminal running on the server, NOT on the thin-client. Both are on my screen
| |
| 20:04 | <vagrantc> ok, so what you want to do is log into the thin-client itself.
| |
| 20:04 | <Schmao-Fmao> Right
| |
| 20:04 | <vagrantc> then you'll be able to see the device nodes on the thin-client
| |
| 20:04 | <jammcq> Schmao-Fmao: you are logging into the thin client? OR, are you using the thin client to log into the server?
| |
| 20:04 | the default is the latter
| |
| 20:05 | <Schmao-Fmao> Okay, jammcq, I might be doing the latter. :P It brings up a graphical login screen, and when I login I get my home directory on the server
| |
| 20:05 | <jammcq> yeah, you are logging into the server
| |
| 20:05 | <vagrantc> Schmao-Fmao: set SCREEN_07=shell in lts.conf ... and then switch to tty7 when the thin-client boots up
| |
| 20:05 | <jammcq> yeah, do what vagrantc said
| |
| 20:05 | <Schmao-Fmao> Gotcha - I'll do that. I have to configure my vmware to take CTRL-ALT-F7 but that should be easy
| |
| 20:06 | Thanks :) I'll try that in the next few minutes
| |
| 20:06 | <jammcq> you are cloning vmware virtual disks ?
| |
| 20:06 | <Schmao-Fmao> no, vmware is just something I'm using to "test" the ltsp server
| |
| 20:06 | <vagrantc> Schmao-Fmao: you may as well set CONFIGURE_X=false as well
| |
| 20:06 | <jammcq> ah
| |
| 20:06 | <Schmao-Fmao> I would be repeating this process with a real computer
| |
| 20:06 | but that's in my office and I'm at home :P
| |
| 20:07 | <vagrantc> Schmao-Fmao: but that should get you a shell on the thin-client itself, rather than the graphical login screen that connects you to the server.
| |
| 20:07 | jammcq: so dberkholz and eharrison just took off. sounds like some decent progress was made :)
| |
| 20:08 | hoping to get another hackfest together in a few months
| |
| 20:08 | <Schmao-Fmao> Gotcha, vagrantc
| |
| 20:08 | I think that screen 7 is the default for the graphical interface anyway, right?
| |
| 20:08 | I shouldn't have to hit CTRL ALT F7
| |
| 20:08 | <vagrantc> Schmao-Fmao: well, this will not be a graphical interface.
| |
| 20:08 | Schmao-Fmao: it will be a shell
| |
| 20:09 | <Schmao-Fmao> Right
| |
| 20:09 | I set it to the shell when I edited lts.conf
| |
| 20:09 | lls has joined #ltsp | |
| 20:09 | <Schmao-Fmao> I meant, I shouldn't have to switch to tty7 because that's the default, am I correct?
| |
| 20:09 | <vagrantc> Schmao-Fmao: if you want a graphical interface, you should be able to install gdm in the chroot
| |
| 20:09 | <Schmao-Fmao> I don't need one
| |
| 20:10 | <vagrantc> Schmao-Fmao: i think you will have to switch to tty7, because it's not running the graphical interface
| |
| 20:10 | <Schmao-Fmao> Gotcha
| |
| 20:10 | then I'll configure my vmware to take ctrl alt f7 :)
| |
| 20:10 | Now that my image is updated, I'll restart tftpd-hpa
| |
| 20:10 | but I don't have to restart anything else
| |
| 20:10 | <vagrantc> Schmao-Fmao: it will default to tty1, is my guess, and that will present you with a login screen on the thin client, for which there are no valid passwords.
| |
| 20:11 | SCREEN_07=shell just gives you a root shell.
| |
| 20:11 | <Schmao-Fmao> then I'll set SCREEN_01=shell as well :)
| |
| 20:12 | <vagrantc> and if you don't disable the getty on tty1, then you'll have both a shell and a login proigram running simultaneously.
| |
| 20:12 | <Schmao-Fmao> and the shell will be running behind?
| |
| 20:12 | <vagrantc> you will have extremely bizarre, confusing, and unexpected behaviors.
| |
| 20:12 | so....
| |
| 20:12 | just trust me here.
| |
| 20:13 | <Schmao-Fmao> gotcha, I won't do SCREEN_01=shell then
| |
| 20:13 | <vagrantc> because both the shell and the login program will be reading your input and giving appropriate output at the same time.
| |
| 20:14 | so you type a shell command, and then you'll get Password: as well as the output of the shell command.
| |
| 20:15 | <Schmao-Fmao> Gotcha I see :) I figured out how to hit ctrl alt f7 on vmware so I'm all set, I think
| |
| 20:15 | <vagrantc> hopefully you can see the devices now...
| |
| 20:15 | <Schmao-Fmao> I'll restart tftpd-hpa and tell you what I get :)
| |
| 20:16 | <vagrantc> restarting the tftp server shouldn't really come into play here ...
| |
| 20:16 | <Schmao-Fmao> I've been restarting the tftp server each time I edit the pxelinux.cfg/default file
| |
| 20:16 | this isn't exactly the same thing
| |
| 20:16 | but in general I've restarted it whenever I update things on the server
| |
| 20:16 | <jammcq> no need
| |
| 20:16 | * vagrantc has never needed to restart it when updating files | |
| 20:17 | <Schmao-Fmao> okay, it says "no job control in this shell"
| |
| 20:17 | and ..
| |
| 20:17 | <vagrantc> Schmao-Fmao: sounds about right ... so the first thing you'll notice ... is there's no job control :)
| |
| 20:17 | <Schmao-Fmao> the /home directory is empty
| |
| 20:17 | <jammcq> sounds right
| |
| 20:17 | no users configured on the thin client
| |
| 20:17 | <Schmao-Fmao> there is no /dev/sda
| |
| 20:18 | let me check for hda or something
| |
| 20:18 | <jammcq> prolly need to load some kernel modules
| |
| 20:18 | lls has left #ltsp | |
| 20:18 | <Schmao-Fmao> got it .. meaning I need to type modprobe -i filename.ko, am I correct?
| |
| 20:19 | <jammcq> yeah, the trick is figuring out what 'filename' is
| |
| 20:19 | <Schmao-Fmao> but I am on the LTSP client now. Where can I get kernel modules?
| |
| 20:19 | <jammcq> same place
| |
| 20:19 | <vagrantc> Schmao-Fmao: probably just modprobe modulename
| |
| 20:19 | <jammcq> yeah, modprobe doesn't need .ko
| |
| 20:19 | <Schmao-Fmao> okay, I'll do find / -name "*ko"
| |
| 20:19 | and try to find out which one it is
| |
| 20:19 | wow
| |
| 20:19 | there are lots =P
| |
| 20:19 | hah
| |
| 20:20 | oh boy, I can't stop it
| |
| 20:20 | <vagrantc> Schmao-Fmao: do you have a booted system running that has the same type of drive loaded?
| |
| 20:20 | Schmao-Fmao: yea no job control ...
| |
| 20:20 | <Schmao-Fmao> Yes, the machine that VMware is running on has that drive loaded
| |
| 20:20 | <vagrantc> Schmao-Fmao: because you could find the module name from the /sys attributes for the device
| |
| 20:21 | <Schmao-Fmao> let's see .. if I google "SATA kernel module", would it come up?
| |
| 20:21 | otherwise I can google how to get sys attributes
| |
| 20:22 | <vagrantc> Schmao-Fmao: cd /sys/block
| |
| 20:22 | <Schmao-Fmao> oh, nice :) there are files under sda
| |
| 20:23 | the files under sda don't tell me the module name
| |
| 20:23 | I'll look around
| |
| 20:24 | None of the files seem to say
| |
| 20:25 | <vagrantc> /sys/block/FOO/device/driver/module
| |
| 20:25 | edgarin has joined #ltsp | |
| 20:25 | <vagrantc> Schmao-Fmao: that should be a symlink to the module name ... at least on debian systems it is
| |
| 20:26 | <Schmao-Fmao> Ah, modalias
| |
| 20:26 | that's probably the same thing
| |
| 20:26 | alias for the module
| |
| 20:26 | and then I can translate it to the module name somehow
| |
| 20:26 | it's not under "driver" though, under "driver" there's only "bind" and "unbind"
| |
| 20:26 | <vagrantc> i didn't find modalias to be useful... do you have a /sys/block/FOO/device/driver/module symlink?
| |
| 20:26 | <Schmao-Fmao> No, there aren't
| |
| 20:27 | <vagrantc> ok... well... i'm at a loss then
| |
| 20:27 | <Schmao-Fmao> no problem - I think there's a file in /etc that translates ..
| |
| 20:29 | Intel SATA controller
| |
| 20:29 | ICH9
| |
| 20:29 | driver is ATA_PIIX
| |
| 20:29 | I think ..
| |
| 20:30 | I loaded it, still no /dev/sda
| |
| 20:30 | <jammcq> there's probably about 4 modules that need to be loaded
| |
| 20:30 | sata appears like a SCSI drive. You'll need some scsi modules as well
| |
| 20:30 | sd_{something} probably
| |
| 20:31 | <Schmao-Fmao> gotcha
| |
| 20:31 | I'll look for them with "find"
| |
| 20:32 | <vagrantc> Schmao-Fmao: narrow your search with /lib/modules
| |
| 20:32 | <jammcq> try sd_mod and scsi_mod
| |
| 20:32 | <vagrantc> Schmao-Fmao: actually, look at /proc/modules on the running server
| |
| 20:32 | <jammcq> you might try loading both of those
| |
| 20:33 | <Schmao-Fmao> can I actually do this:
| |
| 20:33 | find . -name "*.ko" | xargs modprobe
| |
| 20:33 | or is that pretty silly ..
| |
| 20:33 | <vagrantc> that is a foolish thing to do.
| |
| 20:33 | <jammcq> I wouldn't
| |
| 20:34 | <Schmao-Fmao> jammcq, I loaded both sd_mod and scsi_mod, there's still no /dev/sda
| |
| 20:34 | <jammcq> try 'libata' too
| |
| 20:35 | and ata_piix and ata_generic
| |
| 20:35 | <Schmao-Fmao> mm .. Still nothing there
| |
| 20:36 | Wait ..
| |
| 20:36 | <vagrantc> is there a libata package?
| |
| 20:36 | <Schmao-Fmao> I think this makes a lot of sense -P
| |
| 20:36 | I'm logging in with a virtual machine
| |
| 20:36 | of course there isn't a /dev/sda
| |
| 20:36 | Am I right?
| |
| 20:36 | <jammcq> depends on whether you setup one in vmware
| |
| 20:36 | <vagrantc> does your virtual machine support SATA drive emulation?
| |
| 20:36 | <Schmao-Fmao> But if I were to do this in real life, it ought to be there
| |
| 20:36 | <jammcq> prolly not
| |
| 20:36 | it's either scsi or ata
| |
| 20:36 | <Schmao-Fmao> oh, I don't know that. I just installed vmware, the free version
| |
| 20:37 | <jammcq> in vmware, the default is a scsi disk
| |
| 20:37 | so none of that ata stuff should be needed
| |
| 20:37 | <Schmao-Fmao> When I type in lspci, I don't see the device there
| |
| 20:37 | <vagrantc> is it a PCI device?
| |
| 20:38 | <jammcq> you should be able to see a scsi controller
| |
| 20:38 | yeah, in vmware it is
| |
| 20:38 | <Schmao-Fmao> No SCSI controller
| |
| 20:38 | <jammcq> check your vmware VM config
| |
| 20:38 | see if you created a disk, and if so, what kind
| |
| 20:38 | <Schmao-Fmao> Gotcha
| |
| 20:38 | What you just told me to do
| |
| 20:39 | it ought to work when I boot in with a real machine
| |
| 20:39 | right?
| |
| 20:39 | <jammcq> seems right
| |
| 20:39 | <Schmao-Fmao> The fact that there is no disk under lspci just means that I didn't create a disk with my virtual machine
| |
| 20:39 | <jammcq> disks don't show up in lspci
| |
| 20:39 | only controllers
| |
| 20:39 | * vagrantc thinks time would be better spent verifying than speculating | |
| 20:39 | <jammcq> so you should be seeing a scsi or ide controller
| |
| 20:40 | <Schmao-Fmao> There's an IDE interface
| |
| 20:40 | <jammcq> that *might* be for your disk, but it's more likely for a virtual cdrom
| |
| 20:40 | <Schmao-Fmao> okay, under the VM config the presence of floppies and IDE are set to false
| |
| 20:41 | If I set them to true, then perhaps the disks will show up
| |
| 20:41 | vagrantc has quit IRC | |
| 20:41 | <Schmao-Fmao> but IDE != SATA, right?
| |
| 20:41 | <jammcq> well, it's more than just setting IDE to true
| |
| 20:41 | and right, IDE != SATA
| |
| 20:41 | you need to create a virtual disk
| |
| 20:42 | are you using the free vmware player? or the free vmware-server ?
| |
| 20:42 | <Schmao-Fmao> I installed the free vmware-server
| |
| 20:42 | <jammcq> k
| |
| 20:42 | I use that alot
| |
| 20:42 | <Schmao-Fmao> There must be an example config file I can look at somewhere
| |
| 20:42 | I'll look for it :)
| |
| 20:43 | BGomes has joined #ltsp | |
| 20:44 | <Schmao-Fmao> Okay, I think I found some lines to add to my vmx.cfg
| |
| 20:44 | <jammcq> no
| |
| 20:44 | you really need to use the config editor
| |
| 20:44 | cuz it needs to create the virtual disk file too
| |
| 20:44 | <Schmao-Fmao> gotcha
| |
| 20:45 | <jammcq> which means shutting downt he vm client
| |
| 20:45 | <Schmao-Fmao> Cool, pre-allocating virtual disk :)
| |
| 20:47 | I'm getting errors that say "rejecting I/O to offline device" .. I'll google it
| |
| 20:49 | Oh
| |
| 20:49 | Could it be a permission problem?
| |
| 20:49 | I created it as the root user
| |
| 20:49 | <jammcq> created what?
| |
| 20:49 | <Schmao-Fmao> I ran "vmware" as root
| |
| 20:49 | edgarin has quit IRC | |
| 20:49 | <jammcq> should be ok
| |
| 20:49 | <Schmao-Fmao> which means the virtual disk must have been created as root
| |
| 20:49 | <jammcq> I do all my vmware-server stuff as root
| |
| 20:50 | <Schmao-Fmao> Gotcha, I'll keep looking
| |
| 20:53 | FuriousGeorge has joined #ltsp | |
| 20:53 | <FuriousGeorge> hey all
| |
| 20:54 | <Schmao-Fmao> Hey there
| |
| 20:54 | Google says that some people have had luck removing the disk in the config, then adding it again as an existing disk
| |
| 20:54 | let me see what happens there
| |
| 20:55 | <FuriousGeorge> im researching ltsp, and i'm not understanding a few things. i can set up a diskless x terminal, and it must run its own copy of X. what does ltsp run on the client? just enough of X for xdmcp?
| |
| 20:55 | just the client side?
| |
| 20:55 | <jammcq> yeah, basically
| |
| 20:56 | actually, it no longer uses xdmpc. it uses ssh to launch the session on the server and display to the workstation
| |
| 20:56 | <FuriousGeorge> jammcq: isnt that slower as ssh is encrypted?
| |
| 20:56 | negligible i guess
| |
| 20:57 | <jammcq> it can be. but there's also an option to use ssh to get the session started, but then not tunnel the X over ssh.
| |
| 20:58 | <FuriousGeorge> ah...
| |
| 20:58 | spectra has joined #ltsp | |
| 20:58 | <FuriousGeorge> jammcq: so what is the practical difference from what I would implement with LTSP to what i fuzzily remember about setting up XDMCP 8 years ago?
| |
| 20:59 | from what i recall i was able to get a kdm login in a window of another computer running X, and basically use the remote computer
| |
| 20:59 | <jammcq> ok, what are you trying to do?
| |
| 20:59 | <FuriousGeorge> windows terminal services
| |
| 20:59 | for linux
| |
| 20:59 | <Schmao-Fmao> I closed VMware by accident and now it won't open again :P Maybe this means it's time for me to go to sleep
| |
| 20:59 | <jammcq> heh
| |
| 21:00 | <FuriousGeorge> Schmao-Fmao: check the .writelock files maybe... try launching it from the term and see what happens
| |
| 21:00 | <Schmao-Fmao> gotcha, I'll check it out
| |
| 21:00 | <FuriousGeorge> i dont think you should have writelocks if the VM is off, but dont quote me on that
| |
| 21:01 | <Schmao-Fmao> I am launching it from the terminal
| |
| 21:01 | There are no .WRITELOCK files
| |
| 21:01 | <jammcq> using vmware-server-console ?
| |
| 21:02 | <Schmao-Fmao> I type in vmware on the command line
| |
| 21:02 | <FuriousGeorge> jammcq: i know this must seem like a stupid question, but what does LTSP do that setting up XDMCP didnt do, back in the day? does LTSP just make it easier to administrate?
| |
| 21:02 | <jammcq> LTSP provides an operating system to a diskless thin client
| |
| 21:02 | you obviously need more than just an Xserver
| |
| 21:03 | <FuriousGeorge> Schmao-Fmao: does the command line have anything to say about that?
| |
| 21:03 | <jammcq> a thin client needs a kernel and libraries and /sbin/init and a bunch of other things
| |
| 21:03 | <Schmao-Fmao> yeah but I can't cut / paste it, one sec I'/usr/lib/vmware-server/bin/vmware: /usr/lib/vmware-server/lib/libpng12.so.0/libpng12.so.0: no version information available (required by /usr/
| |
| 21:03 | * jammcq thinks Schmao-Fmao isn't using 'vmware-server' | |
| 21:03 | <jammcq> hmm
| |
| 21:03 | <FuriousGeorge> jammcq: so in a manner of speaking, its like XDMCP for diskless stations? again, keep in mind my knowledge of xdmcp is very outdated?
| |
| 21:04 | <Schmao-Fmao> Oh, sorry about that ..
| |
| 21:04 | I was trying to paste it, one moment
| |
| 21:04 | Here's what the command line says
| |
| 21:05 | "/usr/lib/vmware-server/bin/vmware: /usr/lib/vmware-server/lib/libpng12.so.0/libpng12.so.0: no version information available (required by /usr/"
| |
| 21:05 | <jammcq> FuriousGeorge: xdmcp is just a protocol for starting a session. if you have a server computer and a workstation computer, you can tell the Xserver to us xdmcp to start a session on the other machine.
| |
| 21:05 | LTSP provides the entire operating system needed to even get to the point where XDMCP would be used
| |
| 21:05 | <Schmao-Fmao> jammcq: I have vmware-server installed, I just checked
| |
| 21:06 | <FuriousGeorge> jammcq: ok, im starting to wrap my mind around it a bit better now...
| |
| 21:06 | <jammcq> Schmao-Fmao: vmware-server runs in the background. you then need a console program, like vmware-server-console, or the web-based thingy to access that background vmware-server
| |
| 21:06 | the only way I've used vmware-server is through vmware-server-console
| |
| 21:08 | <Schmao-Fmao> From the command line, I typed in "vmware", and before, a console would come up
| |
| 21:08 | Now, nothing comes up
| |
| 21:08 | I don't think I have a command called vmware-server-console
| |
| 21:09 | I have vmware vmware-authtrusted vmware-config-network.pl vmware-mount.pl vmware-serverd vmware-authd vmware-cmd vmware-loop vmware-ping vmware-vdiskmanager
| |
| 21:09 | <jammcq> try vmware-cmd -l
| |
| 21:10 | <Schmao-Fmao> The command doesn't return an error but nothing appears
| |
| 21:10 | hold on. I'll close the window and reconnect
| |
| 21:11 | <FuriousGeorge> jammcq: but also, I can have a diskless terminal with X w/o using LTSP... just PXE booting a chroot environment on my host computer... whats better about LTSP than that?
| |
| 21:12 | <jammcq> LTSP gives you that chroot environment
| |
| 21:12 | <Schmao-Fmao> I have the same issue as before. "/usr/lib/vmware-server/bin/vmware: /usr/lib/vmware-server/lib/libpng12.so.0/libpng12.so.0: no version information available (required by /usr/lib32/libcairo.so.2)
| |
| 21:12 | <jammcq> sure you can build the chroot yourself
| |
| 21:12 | <Schmao-Fmao> I think this message came up even when the console did pop up
| |
| 21:12 | <jammcq> or, you can use LTSP to do that for you
| |
| 21:12 | <FuriousGeorge> jammcq: so ltsp is a framework for administration
| |
| 21:12 | spectra has quit IRC | |
| 21:12 | <jammcq> Schmao-Fmao: that's not a critical error. I get that too
| |
| 21:13 | <Schmao-Fmao> Yeah, I thought so
| |
| 21:13 | <jammcq> FuriousGeorge: well, yeah.
| |
| 21:13 | <Schmao-Fmao> I wasn't 100% sure though
| |
| 21:13 | <FuriousGeorge> which is kinda what i expected, i just didnt understand how it was working. now i understand a little
| |
| 21:14 | <Schmao-Fmao> Should I kill all the processes that have "vm" in the name and then restart?
| |
| 21:15 | <jammcq> you could try: /etc/init.d/vmware restart
| |
| 21:15 | <Schmao-Fmao> mm .. still the same issue
| |
| 21:15 | It returns me to the command line right away
| |
| 21:15 | <jammcq> man vmware
| |
| 21:17 | <Schmao-Fmao> I think the issue may be that I didn't close vmware properly
| |
| 21:17 | but after restarting it, I thought the problem would've gone away..
| |
| 21:17 | maybe I can uninstall and reinstall it, but that's kind of a brute force method
| |
| 21:17 | and it might not even work
| |
| 21:18 | <jammcq> vmware server isn't meant to be run the way vmware-workstation was
| |
| 21:18 | I'd install vmware-server-console
| |
| 21:18 | do you have vmware-serverd running?
| |
| 21:18 | <Schmao-Fmao> Yes
| |
| 21:18 | <jammcq> install vmware-server-console, and use that to attach to vmware-serverd
| |
| 21:19 | <Schmao-Fmao> I'll try. It isn't one of the programs on the list, I have to find the .deb somewhere
| |
| 21:19 | <jammcq> did you install vmware-server from a deb?
| |
| 21:19 | <Schmao-Fmao> I used apt-get
| |
| 21:20 | I think I already have all the repositories
| |
| 21:20 | <jammcq> hmm, dunno how current that is, and if vmware-server-console is available
| |
| 21:20 | I install vmware from the vmware website
| |
| 21:20 | <Schmao-Fmao> I ought to uninstall my current version then
| |
| 21:20 | hold on...
| |
| 21:23 | I got a segfault when I ran vmware-install.pl
| |
| 21:23 | Could it be that I'm on a 64-bit operating system?
| |
| 21:23 | would that cause it?
| |
| 21:23 | <jammcq> I doubt it, i'm using 64-bit
| |
| 21:23 | vmware-install.pl is a perl script
| |
| 21:23 | <Schmao-Fmao> Right
| |
| 21:23 | <jammcq> no way that should cause a segfault
| |
| 21:24 | <Schmao-Fmao> It must have called some other binary
| |
| 21:24 | <jammcq> wonder if the kernel is in a funky state, after vmware was shutdown
| |
| 21:24 | <mistik1> ping
| |
| 21:24 | <Schmao-Fmao> hm .. I can't restart it now
| |
| 21:25 | I'm at home and the computer is at work - I'll go in early tomorrow and see what happens
| |
| 21:26 | if I restart it, it'll net-boot into the thin client mode
| |
| 21:26 | oh, by the way, one last question ..
| |
| 21:26 | How does LTSP set up the TFTP prefix?
| |
| 21:26 | I want to be able to edit it, but I wasn't able to find the location of the TFTP prefix via google
| |
| 21:27 | <jammcq> look in /etc/inetd.conf
| |
| 21:27 | it's part of the cmdline when tftpd starts
| |
| 21:28 | <Schmao-Fmao> tftp dgram udp wait.100 root /usr/sbin/tcpd in.tftpd -s -r blksize /var/lib/tftpboot
| |
| 21:28 | That's the top line
| |
| 21:28 | It doesn't seem to have a prefix .. I put that line in when I set the PXE server up
| |
| 21:29 | tftp dgram udp wait.100 root /usr/sbin/tcpd in.tftpd -s -r blksize /var/lib/tftpboot
| |
| 21:29 | That's the bottom line
| |
| 21:29 | <jammcq> ok, so all things served by tftp need to be in /var/lib/tftpboot
| |
| 21:29 | <Schmao-Fmao> no wait
| |
| 21:29 | sorry, I pasted the top line twice
| |
| 21:30 | So here's the second line that I already commented out before. "#2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img"
| |
| 21:30 | I've been editing the contents of /var/lib/tftpboot for a while
| |
| 21:30 | It appears not to be using the /var/lib/tftpboot/pxelinux.cfg/default file
| |
| 21:30 | It's using /var/lib/tftpboot/ltsp/i386/pxelinux.cfg
| |
| 21:31 | so there's a prefix /ltsp/i386
| |
| 21:31 | <jammcq> what's "filename" set to in your dhcpd.conf file?
| |
| 21:31 | <Schmao-Fmao> pxelinux.0
| |
| 21:31 | Wait .. Could the prefix be in there?
| |
| 21:32 | <jammcq> well, it could be "i386/pxlinux.0"
| |
| 21:32 | <Schmao-Fmao> I can't tell 'cause it's a binary
| |
| 21:32 | <jammcq> what is?
| |
| 21:32 | no, it's not in pxelinux.0
| |
| 21:32 | <Schmao-Fmao> The filename is just pxelinux.0
| |
| 21:32 | <jammcq> grep filename /etc/dhcp3/dhcpd.conf
| |
| 21:32 | <Schmao-Fmao> there's quotes but that's it
| |
| 21:33 | spectra has joined #ltsp | |
| 21:34 | <Schmao-Fmao> all right. I found /etc/ltsp/dhcpd.conf
| |
| 21:34 | And in there, the filename is different
| |
| 21:34 | <jammcq> ah, you are using Ubuntu
| |
| 21:34 | <Schmao-Fmao> How come the dhcp-server is using a different dhcpd.conf?
| |
| 21:34 | <jammcq> I was thinking Debian
| |
| 21:35 | <Schmao-Fmao> It used to use the one in etc/dhcp3
| |
| 21:35 | <jammcq> cuz that's the way Ubuntu decided to handle it
| |
| 21:35 | <Schmao-Fmao> Gotcha .. sorry for the confusion
| |
| 21:35 | Is there a way for me to redirect the DHCP server to look at etc/dhcp3/dhcpd.conf?
| |
| 21:35 | <jammcq> yeah, remove /etc/ltsp/dhcpd.conf
| |
| 21:35 | or rename it to get it out of the way
| |
| 21:35 | <Schmao-Fmao> Okay, got it
| |
| 21:36 | I'll do that in case LTSP doesn't work out for me
| |
| 21:37 | I'm looking for solutions that allow me to clone systems, and that led me to LTSP .. the clients can boot with LTSP, then I'll use "dd" to write an image file, stored on the server, directly to the client's HD
| |
| 21:37 | I've tried to net-boot with a variety of live CD's, but all of them fail at some point
| |
| 21:37 | so maybe LTSP is the best thing to use. It ought to support my network hardware
| |
| 21:38 | <jammcq> LTSP has been used for that in the past
| |
| 21:38 | <Schmao-Fmao> That's the only thing I'm unsure about, as LTSP worked for my virtual machine, but my real machine has some relatively new network hardware that sometimes isn't reconized
| |
| 21:38 | <jammcq> get on the ltsp-discuss mailing list and ask for others doing this
| |
| 21:38 | J45p3r has quit IRC | |
| 21:38 | <Schmao-Fmao> mm, I should. First I should get off all the mailing lists that I don't read =D
| |
| 21:38 | I already get a lot of stuff in my mailbox
| |
| 21:39 | <jammcq> well, LTSP on Ubuntu should have the latest drivers, so hardware compatibility shouldn't be a problem
| |
| 21:39 | <MacIver> Schmao-Fmao: dells?
| |
| 21:39 | <Schmao-Fmao> no, we built them from parts
| |
| 21:39 | they have an ASUS motherboard
| |
| 21:39 | <MacIver> Schmao-Fmao: ah, i had some issues with new dells needing updated e1000
| |
| 21:39 | <Schmao-Fmao> ah, I don't think the hardware is *that* new :)
| |
| 21:40 | It's supposed to be in kernels after 2.6.21
| |
| 21:40 | but the debian-live CD that I got to netboot has kernel version 2.6.18
| |
| 21:41 | <MacIver> Schmao-Fmao: the edubuntu one is 2.6.22 iirc
| |
| 21:42 | <Schmao-Fmao> Gotcha, so you're saying LTSP will probably work. :) That's good
| |
| 21:42 | I need to shuffle some things around, because LTSP seems to have modified my DHCP server
| |
| 21:43 | Ideally, I wouldn't have used LTSP .. It requires me to install quite a few things on my master node .. I would rather have gotten one of the live CD's to netboot properly
| |
| 21:45 | maybe LTSP is a better solution in the end
