| 08:23 | <alkisg> Hrm, new project... to install an ltsp server to a usb stick, and then in order to prevent the stick from being overused, to boot it with init=/boot/init-ltsp, in ro+tmpfs+cow mode...
| |
| 08:23 | :)
| |
| 08:23 | And, to use the stick itself as the image to be published
| |
| 08:24 | i.e. nbd-server will directly serve /dev/sda1
| |
| 08:26 | <Hyperbyte> alkisg, why not go all the way and PXE boot from the cloud? ;-)
| |
| 08:28 | <alkisg> It would be nice if we had gigabit internet connections :)
| |
| 08:32 | <Hyperbyte> We do. :-)
| |
| 08:37 | * alkisg wonders if LTSP, LDM etc work fine with SERVER=localhost | |
| 08:48 | * alkisg loves ltsp-pnp, a dpkg-reconfigure grub-pc; init=/sbin/init-ltsp was all that was needed to get cow+LDM instead of lightdm :) | |
| 08:52 | gbaman has left IRC (gbaman!~gbaman@host81-148-140-104.in-addr.btopenworld.com, Remote host closed the connection) | |
| 08:59 | <alkisg> And an LDM_SERVER=localhost plus a small bug fix away, it's possible to login with the existing users in a temporary environment
| |
| 08:59 | Best live cd ever!!! To customize it all you need to do is boot without init=/sbin/init-ltsp...
| |
| 08:59 | *live usb stick
| |
| 09:11 | <elias_a> alkisg: Nice to know & hear! :)
| |
| 09:11 | <alkisg> I'll write a tutorial for that when I finish it...

| 09:24 | <alkisg> Haha, implementing autologin in the live usb stick is now as easy as LDM_AUTOLOGIN=administrator...
| |
| 09:25 | No need for casper, liveboot and other packages

| 10:05 | <alkisg> The client successfully booted and logged in!
| |
| 10:06 | All that was needed was an /etc/lts.conf on the "server" (=stick), and to modify one line in the ltsp sources

| 16:45 | <juan_> Hello, I just started using epoptes and would like to know how to add a computer
| |
| 16:47 | Hi someone there?
| |
| 16:50 | <alkisg> Hi juan_
| |
| 16:50 | Did you read the installation page?
| |
| 16:51 | <juan_> No
| |
| 16:51 | <alkisg> vsuojanen: I will, when I write the tutorial
| |

| |
| 16:51 | <juan_> Thanks
| |
| 16:55 | <vsuojanen> alkisg nice, thanks

| 18:21 | uXus has joined IRC (uXus!~uXus@217.77.222.72) | |
| 18:24 | <alkisg> vagrantc: I installed ubuntu + ltsp on a usb stick normally, like I would install it on a hard disk. Then, I put this in /etc/lts.conf: https://paste.debian.net/312227/
| |
| 18:24 | I also symlinked /opt/ltsp/images/i386.img to /dev/disk/by-uuid/path-to-the-stick-partition, and /opt/ltsp/i386 to /
| |
| 18:24 | Now I'm able to do the following:
| |
| 18:24 | 1) To boot the stick normally, like I would boot an external hard disk, to install packages in it etc
| |
| 18:25 | 2) To boot it in cow mode, by just adding `init=/sbin/init-ltsp` in the cmdline (dpkg-reconfigure grub-pc to make it permanent). This prevents the usb stick from wearing out from frequent use.
| |
| 18:26 | Then this is an ltsp server, I can serve the usb stick partition to multiple clients in the network. No need for an additional /opt/ltsp/images/i386.img, I'm serving the whole partition.
| |
| 18:27 | 3) I can have a [mac:address] section in /etc/lts.conf for some client that doesn't have enough ram, and disable a whole lot of services. This allows me to boot a recent distro in a client with 128 MB RAM!
| |
| 18:28 | So, editable stick, cow stick, ltsp server, very light stick... 4 in 1 :) And all that's already supported with upstream LTSP code, except for a few INIT_COMMANDs that need to be ran until a couple of small things are fixed upstream :)

| 20:51 | <tubaclarinet> Hello every1...I'm getting "PXE-E61: Media test failure, check cable" error on 1 client while others boot w/out issue.
| |
| 20:51 | <maldridge> tubaclarinet: sounds like the cable is unplugged
| |
| 20:52 | <tubaclarinet> That's what I thought too, but it is plugged in
| |
| 20:52 | <vagrantc> bad cable?
| |
| 20:52 | bad port on switch?
| |
| 20:52 | bad port on client?
| |
| 20:53 | <tubaclarinet> Port is fine...works with Windows

| 20:59 | brianr_ has left IRC (brianr_!~brianr@out.ewbc.com, Quit: Leaving) | |
| 21:05 | <vagrantc> dhcp not configured to give any leases to that mac address?
| |
| 21:05 | broken PXE stack on the client?
| |
| 21:06 | is it plugged into a switch, or directly to the server? if plugged in directly, autonegotiation of the link status may take longer than PXE is willing to wait...
| |
| 21:07 | Faith has left IRC (Faith!~paty_@unaffiliated/faith, Quit: Leaving) | |
| 21:13 | <tubaclarinet> A thousand pardons...i had to step away from my desk
| |
| 21:14 | I forgot 2 mention that I am using LTSP-Live on Edubuntu
| |
| 21:15 | I thought I read somewhere that LTSP-Live can support only up to 8 concurrent clients...is that true?
| |
| 21:23 | <vagrantc> it entirely depends on your hardware ...
