| 03:58 | <jphein> Hello to everyone. =] I have a nice LTSP install in KVM. It's using Ubuntu 18.04.1, with the chrootless dnsmasq proxy method
| |
| 03:59 | However, when I run ltsp-update-kernels my pxe config doesn't pick up the changes I make in /etc/ltsp/udpate-kernels.conf
| |
| 04:00 | my /var/lib/tftpboot/amd64pxelinux.cfg/ directory remains unchanged
| |
| 04:01 | When I make the changes directly in the files it works well
| |
| 04:09 | Am I missing something?
| |
| 05:56 | <alkisg> jphein: yes, /usr/share/ltsp/update-kernels
| |
| 05:56 | This transfers /etc/ltsp/update-kernels.conf to /boot/pxelinux.cfg/default
| |
| 05:56 | Then ltsp-update-image puts it in /opt/ltsp/images/amd64.img
| |
| 05:57 | And finally ltsp-update-kernels gets it from amd64.img and puts it to tftp
| |
| 05:57 | <jphein> Thank you! I'll try it out. =]
| |
| 05:57 | <alkisg> It's so complicated that I wanted to get rid of it and just use a static file :D
| |
| 05:59 | <jphein> hahaha
| |
| 06:08 | So it never goes to /var/lib/tftpboot/ltsp/amd64/pxelinux.cfg/ ?
| |
| 06:17 | I'd like to install Ubuntu as a pxe option before my ltsp menu
| |
| 06:32 | <alkisg> jphein: sure, it goes to pxelinux.cfg after the 4 steps I mentioned above
| |
| 06:38 | <jphein> lol!
| |
| 06:42 | Thank you! Goodnight.

| 07:36 | <stilyan> hi
| |
| 07:37 | ltsp-update-image --cleanup /
| |
| 07:37 | Script //usr/share/ltsp/ltsp-cleanup does not exist, cannot cleanup the chroot.
| |
| 07:37 | <alkisg> stilyan: install ltsp-client on the server
| |
| 07:37 | (I assume you're trying chrootless ltsp, right?)
| |
| 07:37 | !install
| |
| 07:37 | <ltsp> install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
| |
| 07:37 | <stilyan> correct
| |
| 07:37 | <alkisg> Those are the instructions, they include ltsp-client in the apt install line ;)
| |
| 07:38 | When everything else fails... RTFM :D
| |
| 07:38 | <stilyan> thanks
| |
| 07:43 | ricotz has joined IRC (ricotz!~ricotz@ubuntu/member/ricotz) | |
| 08:20 | <stilyan> can I use dnsmasq as tftp only, no dhcp and no sending of boot filename ; all of these I want to be handled by the network router ; it works in regular chroot mode but in chrootless I'm getting tftp timeouts
| |
| 08:21 | nehemiah has joined IRC (nehemiah!~nehemiah@hs-user-138.wia.cz) | |
| 08:24 | <alkisg> Sure, the dnsmasq configuration is the same in both modes, no difference there
| |
| 08:41 | <stilyan> in chroot I pass dhcp option with code 17 and value '/opt/ltsp/amd64' , when chrootless should I pass anything besides the boot filename ? /ltsp/amd64/pxelinux.0
| |
| 08:42 | <alkisg> stilyan: there is really NO difference at all between chroot/chrootless modes in dnsmasq configuration
| |
| 08:43 | In both cases the rootpath is needed for nbd to locate the nbd image
| |
| 08:45 | <stilyan> well poops, tftp timeouts.. have no idea
| |
| 08:47 | <alkisg> stilyan: get a screenshot from the client and upload it for us to see in which part it fails
| |
| 08:47 | (or type here the last 3 lines of the client output)

| 08:55 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 09:26 | <stilyan> shows network addresses, pxe-e32: tftp open timeout .. i tried chroot just to be sure as well.. same there
| |
| 09:27 | previously i tested with ubuntu when it worked, now this is Lubuntu..
| |
| 09:34 | <alkisg> stilyan: you just have your router configuration wrong
| |
| 09:35 | Previously you probably enabled proxydhcp in ltsp, and that bypassed the wrong router configuration
| |
| 09:35 | stilyan: do a vnc if you want more help:
| |
| 09:35 | !vnc-dide
| |
| 09:35 | <ltsp> vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.

| 09:38 | Natureshadow has left IRC (Natureshadow!45d1515d22@commu.teckids.org, Read error: Connection reset by peer) | |
| 09:42 | <stilyan> works with dnsmasq off, probably config issue
| |
| 09:44 | <alkisg> stilyan: if it works with dnsmasq off, just disable dhcp/proxydhcp in dnsmasq
| |
| 09:44 | What's the output of this? grep range /etc/dnsmasq.d/ltsp-server-dnsmasq.conf
