| 14:50 | <soroch> Hi. I installed LTSP on server Debian. And i want to install distribution Ubuntu on think client. How do it?
| |
| 14:57 | ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu) | |
| 15:05 | <sbalneav> soroch: With difficulty.
| |
| 15:06 | <alkisg> soroch: start with this for your first ltsp installation:
| |
| 15:06 | !ltsp-pnp
| |
| 15:06 | <ltsp`> ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 15:06 | * ogra_ prefers to do it with coffee and cake | |
| 15:06 | <sbalneav> I'd make the chroot on a ubuntu server, and copy it over if I was going to try that. Or what alkisg says :D
| |
| 15:06 | Or definitely what ogra_ says
| |
| 15:06 | <ogra_> :D
| |
| 15:07 | <alkisg> Hmmm cooffee... nice idea, +1

| 15:14 | dtcrshr has left IRC (dtcrshr!~datacrush@unaffiliated/datacrusher, Ping timeout: 252 seconds) | |
| 15:14 | <soroch> then, distributive on server = distributive on thin client?

| |
| 16:44 | sophiee has joined IRC (sophiee!c101b8e7@gateway/web/freenode/ip.193.1.184.231) | |
| 16:44 | <sophiee> does anyone know where I can find a minimum file system just to run bash?
| |
| 16:45 | or what is needed for a minimum file system just to run bash?
| |
| 16:45 | <alkisg> sophiee: not related to ltsp?
| |
| 16:46 | What is your operating system currently?
| |
| 16:46 | <sophiee> it is linux mint - i just thought there might be some documentation on this
| |
| 16:46 | <alkisg> sophiee: you already have bash
| |
| 16:46 | Just open a terminal, bash is there
| |
| 16:47 | <sophiee> yeah I have - i need to create a new file system for a client and I need to include what is needed to run bash
| |
| 16:47 | im doing a thin client project :)
| |
| 16:47 | <alkisg> A thin client project without ltsp?
| |
| 16:47 | How is the client going to boot?
| |
| 16:47 | From local disk?
| |
| 16:47 | <sophiee> from a server using DHCP and PXE
| |

| 16:48 | <alkisg> And you don't want the client to do anything else except run bash?
| |
| 16:48 | eu^1191017726 has left IRC (eu^1191017726!770ab11a@gateway/web/freenode/ip.119.10.177.26, Client Quit) | |
| 16:48 | <sophiee> yeah that is all I need for now
| |
| 16:48 | <alkisg> What's wrong with using ltsp direclty?
| |
| 16:48 | E.g. this:
| |
| 16:48 | !ltsp-pnp
| |
| 16:48 | <ltsp`> ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 16:48 | vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc) | |
| 16:48 | <alkisg> That basically means that you run a few commands on your linux mint serverand the client will be ready
| |
| 16:49 | It will even support both thin and fat clients (fat means they're using their own cpu to run programs, but are still diskless)
| |
| 16:49 | ...you should have your client ready in about 20 minutes that way
| |
| 16:50 | <sophiee> ok i was hoping to configure my own with a custom file system
| |
| 16:50 | that is handy though
| |
| 16:50 | <alkisg> You can run ltsp-build-client
| |
| 16:50 | This will generate a minimal chroot, with bash and a few other text mode stuff
| |
| 16:50 | And xorg, to be able to function as a thin client
| |
| 16:50 | But it's the old way to do things :D
| |
| 16:51 | <sophiee> ok i might give it a try!
| |
| 16:51 | thanks!
| |
| 16:51 | <alkisg> Start with ltsp-pnp to see the current state of things
| |
| 16:52 | Then, if you see that you don't like something, *then* try alternatives
| |
| 16:53 | <sophiee> ok will do thank you

| 20:41 | <markit> Problem not strictly related to ltsp: school has bought a multifucntion HP Color Laser Jet M477 or something like that, and has ltsp on (k)ubuntu 14.04. I need hplip >= 3.15, that is NOT in 14.04. I've searched for hilip backports but found nothing
| |
| 20:41 | seems that the only way is to upgrade the ltsp server to 16.04... :(
| |
| 20:41 | (I've not yet tested Kubuntu with 16.04 ltsp)
| |
| 20:42 | anyone faced this issues and solved differently?
| |
| 20:42 | And if I have to upgrade to 16.04, better backup /home and install 16.04 from scratch?
| |
| 20:45 | <alkisg> markit: although you could search for a newer hplip, it sounds like a good time to upgrade to 16.04
| |
| 20:45 | It should be possible with just a "do-release-upgrade", without reinstalling anything
| |
| 20:45 | <markit> alkisg: usually that way is very slow and leaves a lot of crap around, no?
| |
| 20:46 | alkisg: btw, hi, I'm happy to see you :)
| |
| 20:46 | <alkisg> :)
| |
| 20:46 | markit: no, it shouldn't be very different to a new installation
| |
| 20:46 | Slow, yes, it'll need a couple of hours
| |
| 20:46 | But isn't that faster than reinstall and configuring everything?
| |
| 20:47 | Depending on how much you configure things after an installation...
| |
| 20:47 | <markit> alkisg: maybe because I usually use the "kde backports" repost, in the past often the process stalled / aborted / lasted a HUGE time
| |
| 20:47 | <alkisg> Well it shouldn't hurt to try if you plan to reinstall anyway
| |
| 20:48 | <markit> alkisg: sure if you tell me so :)
| |
| 20:48 | <alkisg> About newer versions, some times you can download them from packages.ubuntu.com => a newer ubuntu series than the one you have
| |
| 20:48 | but you need to check the dependencies first
| |
| 20:49 | Because it's possible that they have unmet dependencies that are only there in 16.04...
| |
| 20:49 | <markit> any trouble specific with ltsp? btw, I have some in that school, some clients stuck at boot at a certain point, and sometime they keep booting if I in the meanwhile turn on one more client
| |
| 20:49 | let me take the cell phone with the photo of the screen and write here back the last message
| |
| 20:50 | at time 8 there is "nbd0: unknown partition table"
| |
| 20:51 | ad time 22 randome: noblocking pool is initialized
| |
| 20:51 | <alkisg> That's normal, ltsp images don't have partitions
| |
| 20:51 | <markit> then nothing more
| |
| 20:51 | <alkisg> Normal too, just an info message, no error there
| |
| 20:51 | Upload the photo?
| |
| 20:51 | And what then, it stucks there?
| |
| 20:51 | <markit> yes
| |
| 20:52 | but happend that if I turn on another client, the it "resumes" (continues from there)
| |
| 20:52 | I use dnsmasq if it counts, and a very "underpowered" server
| |
| 20:52 | <alkisg> That doesn't make a lot of senses... :D
| |
| 20:52 | !quiet-splash
| |
| 20:52 | <ltsp`> quiet-splash: to disable the splash screen in Ubuntu, in order to see any boot error messages, run sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and remove quiet splash plymouth:force-splash vt.handoff=7
| |
| 20:53 | <alkisg> Try to remove quiet-splash, and take /upload a photo of the boot process till there
| |
| 20:53 | <markit> I can't now, I've their server here at home but just one client PC, probably does not happen right now
| |
| 20:54 | I have 9 clients there, and just one -two sometime do this (more or less random)
| |
| 20:54 | <alkisg> Can you upload your existing photo?
| |
| 20:54 | <markit> I was surprised, as I told, that turning on the client nearbie resumed the process
| |
| 20:55 | yes, let me download from the cell pone and then ask you where and how upload ;P
| |
| 20:55 | I could send you through gmail?
| |
| 20:56 | <alkisg> If you google for "image upload", there are thousands of sites for that, similar to pastebin
| |
| 20:56 | postimage.io came first in google
| |
| 20:57 | <markit> the real question were "ask you YOUR preferred way to have it uploaded" ;P
| |
| 20:57 | s/were/should have been
| |
| 20:57 | <alkisg> I don't have one :)
| |
| 20:57 | Any link that will show the photo is fine for me
| |
| 21:01 | <markit> https://postimg.org/image/emqzg5w83/
| |
| 21:02 | better
| |
| 21:02 | https://s29.postimg.org/a0uv7tap3/ltsp_client.jpg
| |
| 21:02 | (direct link)
| |
| 21:03 | <alkisg> Hmm yeah I don't see anything wrong there
| |
| 21:03 | If it happens again, wait a bit, then boot another client so that the first one continues,
| |
| 21:03 | and at that time, get the syslog and the dmesg of the client
| |
| 21:05 | <markit> ok, thanks a lot
| |
| 21:05 | time for dist-upgrade now :)
| |
| 21:06 | <alkisg> :)
| |
| 21:06 | Good luck!
| |
| 21:13 | <markit> alkisg: btw, in ltsp-pnp there still is the constrain that the server should have nostname "server" (AFAIR, is a ltsp constrain)
| |
| 21:13 | (also if my server don't have that name and everything seems to work anyway)
| |
| 21:14 | <alkisg> markit, no, that was an issue with cups, i solved it years ago...
| |
| 21:16 | (and it was not an issue with ltsp-pnp... but with ltsp/cups in general)
| |
| 21:22 | <markit> last: do-release-upgrade -m desktop or simply do-release-upgrade ?
| |
| 21:28 | I'm going with # do-release-upgrade

| |
| 23:55 | now aptitude -f install wants to remove a TON of necessary packages
