<danboid>
Hi guys! I decommissioned my bpi so now there will be no dnsmasq conflicts on my home network but PXE/TFTP still isn't working
08:20
I now using DHCP on my router, could that be an issue?
08:21
This will be the config most people at home will be working with, so if special attention is required in this config, it should be noted in the guide
08:21
dnsmasq is running on my LTSP server
08:22
var/run/dnsmasq/resolv.conf is listing some odd values tho
08:23
194.168.4.100 and 194.168.8.100 - not sure where's its got those from
08:23
My router/DHCP server is 192.168.0.1 and my LTSP server 192.168.0.17
08:24
I can't say I have much experience with PXE, TFTP, dnsmasq and friends
08:24
so any tips are appreciated
08:25
alkisg, ^^
08:32
I did the first, recommended DNS fix mentioned in the guide
08:33
THe one where you comment port=0 in /etc/dnsmasq.d/ltsp-server-dnsmasq.conf
08:38
I'm guessing var/run/dnsmasq/resolv.conf should just list 127.0.0.1?

I've tried cutting my router out by using a switch but that hasn't worked
09:04
I'm going to try the second DNS workaround now

I did it! I just did my successful LTSP boot :D
09:25
*my first
09:26
I am using my router DHCP
09:28
<alkisg>
danboid: hi; just came; I have about 5 minutes, do you need anything or all ok now?
09:30
<danboid>
alkisg, Alls looking good right now. I'll have to start messing about with it as I'm sure I'll have more questions later but getting the initial boot working was always going to be the hardest bit
09:30
alkisg, Thanks!
09:31
<alkisg>
Great

alkisg, Are you here?
13:50
alkisg, I'd like to make a few small suggestions for improvements to the LTSP docs
13:50
alkisg, and you said you'd prefer we ask you to do it

22:03

22:03

<fuzzmew>
My ltsp broke again, is there a way to fix without re installing? I'm running mint linux 17.3 and tried to install ltsp but it exited abnormally when i tried to build the client, what am I doing wrong? THanks.
22:40fuzzmew has left IRC (fuzzmew!~fuzzmew@96-18-71-242.cpe.cableone.net, Client Quit)
22:44
<vagrantc>
pretty much impossible to say, fuzzmew ...
22:44
derick_: which username/password entry are you talking about?
22:45
derick_: and what reboots?
22:56
<derick_>
vagrant_: I have uploaded a video - https://youtu.be/oEhW-OykC90
22:56
about the error
23:00
vagrantc_: sorry about misspelling you nick.
23:04
<vagrantc>
no worries
23:04
not really able to look at a video at the moment ... can you describe it with words?
23:05
<derick_>
sure
23:06
<vagrantc>
or cut-and-paste the text, if any
23:06
!pastebin

23:07
<derick_>
okay thanks :) give me a minute.
23:09
<vagrantc>
sure
23:09* vagrantc is in the middle of doing 3-4 things :)

Nice great going. I am also up and working at 4:30am :P
23:34
<vagrantc>
oh, that could could have just mentioned in irc :)
23:34
i vaguely recall some bugs that might trigger this on recent versions of ubuntu ...
23:35
recent versions of ubuntu are unfortunately not well tested the last few years
23:35
!nbd
23:35
<ltsp>
I do not know about 'nbd', but I do know about these similar topics: 'disable-nbd-proxy', 'nbd-proxy', 'nbd-compression', 'quick-nbd-tests', 'nbd-client', 'nbd-server-bug', 'nbd-trusty-bug', 'nbd-client-breaks-nm', 'nbd-bug', 'nbd-checkupdate'
23:35
<vagrantc>
!nbd-checkupdate
23:35
<ltsp>
nbd-checkupdate: To avoid bug https://github.com/NetworkBlockDevice/nbd/issues/59, put this in lts.conf: INIT_COMMAND_RM_NBD_CHECKUPDATE="rm -rf /usr/share/ldm/rc.d/I01-nbd-checkupdate"
23:35
<vagrantc>
derick_: i think that's the one ^^
23:36
that should fix the rebooting issue
23:37
so, ubuntu 18.04, boots ... but at login it adds the ECDSA ssh key ... and then reboots
23:38
derick_: do you have an lts.conf file?
23:38
by default, it should automatically add keys for "server" which is used as an alias for the LTSP server.
23:38
it shouldn't use the ip address, unless you've specified it in lts.conf to use the ip address
23:39
<derick_>
wow. finally someone provided a solution. I was struggling with this for days.
23:39
<vagrantc>
there were some key types that were not supported until recently...
23:40
<derick_>
yes I have lts.conf file I will put that line and let you know what happens.
23:40
<vagrantc>
but there's been support for ecdsa since ltsp 5.2 ~2011
23:40
derick_: have you specified SERVER in lts.conf ? in general, you shouldn't need to.
23:41
<derick_>
no. I am using a lts-pnp setup.
23:41
just did ltsp-config lts.conf
23:41
<vagrantc>
derick_: there's no current active ltsp maintainer in ubuntu ... and while i've tried to keep it working in debian (and ubuntu inherrits) ... i haven't had a real-world LTSP lab for 2-3 years
23:42
derick_: hmmm... curious about the key problem, then
23:42
so my testing is virtual ltsp servers with virtual ltsp clients and just whatever i manage to test for the moment
23:43
alkisg also hasn't had as much time for LTSP the last few years either, who has done most of the significant work for the last several years
23:44
<derick_>
cool. I have automated process of creating virtual ltsp servers with virtual ltsp clients with vagrant and VBoxManage
23:44
I just started working with LTSP.
23:45
Its my google summer of code project :)

23:47
<vagrantc>
oh
23:48
i wasn't too sure about the usefulness of that project, so haven't been involved... but anything putting LTSP through it's paces will be a good thing.
23:48
derick_: so good luck on it! :)
23:49
<derick_>
vagrant_: Thank you =)
23:50
<vagrantc>
derick_: is your mentor in irc as well?
23:50
dashamir hoxha?
23:51
<derick_>
vagrant_: No I dont think he uses IRC
23:51
most of our communication happens through github
23:53
<vagrantc>
ah.
