Channel log from 8 June 2018   (all times are UTC)

00:13
<derick_>
shell-screen method worked. I am logged in as root.
00:13
Had to use right ctrl and f2 because I am on a vm
00:15
<vagrantc>
look for what process is hanging the login
00:15
pstree -a
00:15
at least, i find that useful
00:16
!nbd-checkupdate | echo derick_
00:16
<ltsp`>
derick_ 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"
00:16
<vagrantc>
you did try that? ^^
00:16
also, on the booted system, does /etc/ssh/ssh_known_hosts exist
00:17
<derick_>
yes I had tried nbd-checkupdate
00:17
<vagrantc>
could have checked my loop-mounting the image on the server, actually ...
00:17
<derick_>
yes ssh_known_hosts exist
00:17
<vagrantc>
echo $SERVER ?
00:17
<derick_>
echo $SERVER shows my ip address
00:18
<vagrantc>
ping server
00:18
do you have SERVER defined in /etc/lts.conf ?
00:18
<derick_>
I am able to ping
00:18
<vagrantc>
by the name "server" ?
00:19
<derick_>
no.
00:19
<vagrantc>
by default, ldm basically does ssh -Y $USER@server
00:19
and /etc/ssh/ssh_known_hosts defines has entries for "server"
00:20
derick_: no, you don't have SERVER defined in /etc/lts.conf ?
00:20* vagrantc has to head out soon
00:21
<derick_>
no
00:21
How do I add it?
00:21
just SERVER = my ip address ?
00:23
vagrantc : okay no worries. I will look up on the internet
00:24
<vagrantc>
derick_: it should not be present in lts.conf by default
00:25
derick_: so if i'm understanding you correctly, that's fine
00:25
<derick_>
okay.
00:25
<vagrantc>
derick_: from tty2, can you "ssh server" or "ssh USER@server" ?
00:26
is LDM_SERVER defined?
00:26
in lts.conf
00:26
<derick_>
i cannot ssh server. it gives me same public key denied
00:27
LDM_SERVER is not defined
00:27
<vagrantc>
ssh-keyscan server
00:28
and from the server: ssh-keyscan localhost
00:28
do they look the same?
00:29
<derick_>
no they look different
00:29
<vagrantc>
that's your issue
00:30
or at least, that's probably your issue
00:30
<derick_>
ahh... finally
00:30
<vagrantc>
you said the ltsp server is in virtualbox?
00:30
<derick_>
yes
00:30
<vagrantc>
it's probably sshing to the host machine, not the ltsp server
00:31
<derick_>
That should be the case. How can I fix it.
00:32
we can talk about this later if you want to head out
00:32
<vagrantc>
no idea what vagrant does to networking
00:32
this isn't an LTSP issue; it's a vagrant issue ... probably ask your mentor a bit about it
00:33
or rather, a vagrantup issue ... :)
00:34
though i'm surprised you've got nbd, proxydhcp and/or dhcp working, and not ssh
00:34
maybe try turning off ssh on the server, see if it passes it through to ltsp
00:34
do the LTSP server and host machine
00:35
have different ip addresses?
00:35
<derick_>
yes. I they did something with ssh. If i turn off the ssh I wont be able to control it with vagrant
00:35
<vagrantc>
i meant turning off ssh on the host machine, not the LTSP server
00:36
and is $SERVER in your client the ip address of your LTSP server, or the host machine?
00:37
<derick_>
LTSP server.
00:37
strange
00:37
<vagrantc>
your host server may be listening on all interfaces ... you might be able to restrict it's ssh configuration to not listen on the LTSP server address
00:38
<derick_>
okay. I will look about it.
00:39
Thank you for all the help :) I have been continuously working for last day and night. I have been up last night too and its morning now(check current time in india)
00:39
finally I will be able to sleep well :)
00:39
<vagrantc>
be sure to take reasonable breaks :)
00:41
<derick_>
haha. Yeah sure. Thank you again :)

alkisg: 2a18cc5bdfaadac5b5e0ad5a41eda37e97b0caf3 introduced a bug in HOSTNAME_EXTRA ...
01:30
awk: line 1: sytax error at or near *
01:30
given the sheer number of * in there ... eesh.
01:35
alkisg: seems the ** aren't valid with the default awk on debian
01:35
alkisg: it almost works just turning those into single *
01:48
alkisg: seems like ^ should be used instead of **
01:49
yup, that seems to fix it for me.
01:50
arguably easier to read.
01:52
** appears to be some sort of non-posix extension ...

alkisg: these?
16:16
I managed to make my client laptop, find the ltsp image, only when it is starting to stagnate in one part and I receive the following message 'nonblocking pool is initialized'
16:18
I did not mention you, that I'm using a different dhcp than the built-in ltsp-server

16:20
<cvillasboa>
but, I stopped the dhcp service from the ltsp server
16:21
We use pfsense as dhcp in the company where I work
16:23
<morandiBrasil>
hello please Does anyone have a tutorial on how to integrate a non-DHCP LTSP server into a Samba PDC?
16:23
<cvillasboa>
Going back to my previous problem, the reason why I could not find my network image is because my adapter was in uefi mode
16:23
alkisg: you were right
16:27vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
16:44
<||cw>
morandiBrasil: just have to add the PXE address option to the dhcp, might have to consult the samba docs on how to add options

Does the ltsp thin client require a hard drive? or is everything done on the server
17:36
thin client is not booting via the network
17:37
tftp error file missing
17:38
<alkisg>
Guest71462: ltsp thin and fat clients do not require a hard drive

If you get an error, paste the output of `sudo ltsp-info | nc termbin.com 9999`
17:39
cvillasboa: try this
17:39
!ipappend
17:39
<ltsp`>
ipappend: o temporarily solve DHCP problems in the initramfs, try putting IPAPPEND 3 after the APPEND line in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default. More info: http://www.syslinux.org/wiki/index.php/SYSLINUX#IPAPPEND_flag_val_.5BPXELINUX_only.5D
17:41
<Guest71462>
dhcp seems to be working fine
17:44
<alkisg>
Guest71462: the name in front of the lines is the one I'm speaking to
17:45
So I asked YOU for ltsp-info, and cvillasboa about ipappend
17:46

Guest71462: please read what I wrote, I used "termbin" there
17:47
You can't paste many lines in irc
17:47
They are either cut, or you get kicked for flooding
17:47
(08:39:09 μμ) alkisg: If you get an error, paste the output of `sudo ltsp-info | nc termbin.com 9999`

<Guest71462>
sorry ... newbie
17:47

np
17:52
<Guest71462>
No LSB modules are available.
17:52
http://termbin.com/9a91
17:52
thats all it says
17:55
ah, now I see what termbin is
17:55
<alkisg>
Guest71462: ok, you have all the necessary packages although you're not using the ppa
17:55
Anyways, sounds like a dhcp/tftp misconfiguration
17:55
Which tftp server are you using, tftpd-hpa or dnsmasq? check their logs, to see which file isn't there
17:56
<Guest71462>
the client does see and go to the correct ip address when it attempts the pxe boot
17:57
not sure...easy way to find out? (sorry, real newb)
17:57

!ltsp-pnp
17:57
<ltsp`>
ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp

I am having problem for ltsp5 i386 working with MSTI PSX 1000MHz (http://www.helpinformatica.info/ler_oferta.php?codigo_oferta=39) - is it possible to work?
20:47Faith has left IRC (Faith!~Paty_@unaffiliated/faith, Quit: Leaving)
20:49
<alkisg>
avena: does it boot e.g. ubuntu? If yes, then it can run ltsp

<ltsp`>
cheap-client: https://www.gearbest.com/tv-box-c_11262/?attr=2081-1279
20:50
<alkisg>
But in general, you can buy 10 times faster clients under 100 euros
20:50
So it might not be worth it to spend days to get ancient hardware running

a friend already bought the terminals, did not consult me. the old microcomputers works perfectly, but this one of error. https://imgur.com/FH5MtLE

<avena>
This kernel requires an i586 CPU, but only detected an i486 CPU - https://imgur.com/pMGGoD3 - I believe that my friend was prejudiced in the purchase. if I try ltsp4.2, could it work?
21:08
<alkisg>
avena: I think debian wheezy should work good
21:09
avena: how many terminals?
21:10
<avena>
I believe that 20 terminals.
21:11
I'm in São Paulo - Brazil, my friend is in Rio de Janeiro, I'm helping remotely
21:11
<alkisg>
So 20 486 processors, that would cost like 100 euros? Throw them away :D
21:11
<avena>
:)
21:12
<alkisg>
You could also try ubuntu 10.04 or 8.04
21:12
<vagrantc>
wow
21:17
<avena>
install debian 9.0, in the chroot environment of ltsp put debian 7.0 - Wheezy. ltsp-build-client ---- mirror for debian repositories 7.0 can you allow me to do this?
21:17
<alkisg>
Some software is not compatible between 9 and 7. You might need debian 7 on the server too.
21:18
When I tried to boot an ubuntu 8.04 chroot from an ubuntu 16.04 server, it took me a couple of days to fix all the problems
21:21
<avena>
I'm going to sit down and cry.
