<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.

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

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
08:21nehemiah 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)

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.

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
