<huafu>
hello, anyone here who could help with some DHCP issues and my LTSP clients?
06:59
I see the DHCP requests and offers from in the syslog of the server but none of my clients seems to see the offers (responses)
07:00
the issue is not client side, they use to boot correctly on other config
07:01
but now I wanted my ltsp server to be a VM, so I setup my NIC as manual, in the vbox params I allowed promiscuous mode, setup as bridge of course, used AMD but tried with intel and it is the same
07:01
<maldridge>
having not tried to do such things from a VM, I'd be sure that your VM is forwarding the packets back out
07:02
<huafu>
in the client vm (ie ltsp server) I used a very basic configuration, no extra config
07:02
<alkisg>
Is that your only dhcp server?
07:02
<huafu>
maldridge, alkisg thanks for answering
07:02
<alkisg>
Or do you have another dhcp server (e.g. router) in your network?
07:02
<huafu>
alkisg, on that network yes it is the only dhcp server (the VM, ltsp server)
07:02
the router is on another NIC
07:03
<alkisg>
Which nic is the host nic that is bridged to the VM? eth1?
07:03
Run this from your host: sudo /usr/lib/klibc/bin/ipconfig -n eth1
07:04
This tries to get an ip without actually assigning it. The VM should answer.
07:04
<huafu>
alkisg, FYI I started from scratch and decided to follow the tuto before doing some fancy config, and to allow me to revert quickly I decided to use a very basic ubuntu server as the host os, and the vm would be the ltsp server. on the host, eth0 is the internet, and eth1 is the lan with my ltsp clients. The eth1 on the host is configured as `inet manual`
07:05
<alkisg>
The quickest way to have something up and running is to follow the wiki page without testing e.g. if ubuntu server works :)
07:05
What's the output of that command that I said above?
07:06
<huafu>
the interfaces are the same name in the guest (eth0 and eth1), I do have access to the internet, I configured my eth1 as fixed in the guest os (as explained in your pnp tuto, only change is a different network and no dnsmasq)
07:06
<alkisg>
dnsmasq is automatically configured for 2 nics
07:06
<huafu>
ok lemme run that command, sorry was expalining everything before reading lol
07:07
<alkisg>
and tftpd-hpa has issues, so dnsmasq is again better there
07:07
So after a couple of days of troubleshooting, you'll end up discovering the bugs that I found a couple of years ago, before writing the tutorial :)
07:08
<huafu>
dnsmasq is also dhcp server?
07:08
<alkisg>
Yes, it's automatically configured by ltsp-pnp
07:08
You only need to set eth1=192.168.67.1 from network-manager
07:08
...as the wiki page says
07:08
<huafu>
well the other day I was using isc and it was working, and also I am not used to dnsmasq but isc, that is why
07:09
ah, and I do not want to use network manager ;-)
07:09
<alkisg>
Sure if you want ltsp not to work, you can not follow the page
07:09
:)
07:09
<huafu>
alkisg, the last setup with isc was working
07:09
<alkisg>
OK, bug solving is always nice, you can take 1 month to solve all the related bugs upstream and in ubuntu, in launchpad etc
07:09
Yes
07:10
tftpd-hpa is not working with ubuntu though, it sometimes doesn't start
07:10
<huafu>
ok if dnsmasq provides the same as isc then I'll switch and learn
07:21
<alkisg>
dnsmasq is lower quality than isc but provides more things for netbooting, like e.g. proxydhcp, tftp, dns...
07:21
ltsp-config dnsmasq gives you a configured file for your ltsp server
07:22
There's no ltsp-config isc-dhcp-server, noone cared enough to implement it
07:27
<huafu>
yeah saw that ;-)
07:28
so I disabled the lines about proxying in the config file, and added a line so that it listen only on eth1, plus gave a correct range of IP, is that ok? (in your config you suppose there is already a dhcp server and I do not have so (at least on the NIC for ltsp)
07:29
<alkisg>
huafu: run ltsp-config --overwrite
07:29
And set eth1=192.168.67.1
07:29
That's all
07:29
Don't improvise
07:29
ltsp-config dnsmasq --overwrite
07:29
Your use case is documented in the wiki
07:29
There's no need to implement it yourself
07:31
<huafu>
I guess I am missunderstanding stuff
07:31
shouldn't I need a dhcp server?
07:32
<alkisg>
ltsp-config dnsmasq --overwrite configures a dhcp server for you
07:32
In the 192.168.67.1 subnet
07:32
You only need to set the eth1 ip to that
07:32
<huafu>
oh ok, thanks
07:40
alkisg, I have the same issue as before :/
07:40
and the output of the command you gave me is
07:40
IP-Config: eth1 hardware address 90:f6:52:03:9b:58 mtu 1500 DHCP RARP
07:41
only that, then it hang for some time and then exit
07:41
<alkisg>
huafu: run a vnc for me to see:
07:41
!vnc-dide
07:41
<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.

hi
07:47
anybody on?
07:47
<alkisg>
Hello
07:48
huafu: the vnc is stack, is your internet connection extremely slow or it hanged?
07:48
huafu: try to go to the root terminal so that I see if it changes
07:48
<xdrazen>
well, i am having some issues...
07:48
service isc-dhcp-server restart
07:48
it shows "failed"
07:49
<alkisg>
Use dnsmasq :)
07:49
<xdrazen>
had better with that?
07:49
<alkisg>
xdrazen: weren't you going to use the ltsp-pnp page?
07:50
I thought that the last time you were going to try with ubuntu 12.04 + ltsp -pnp..
07:50
<xdrazen>
i was going to... bur i downloaded "ubuntu 12.04.5" just today
07:50
<alkisg>
We said 12.04.1
07:50huafu has left IRC (huafu!~huafu@node-j9w.pool-1-2.dynamic.totbb.net, Ping timeout: 240 seconds)
07:50
<alkisg>
Because of your s3 virge cards
07:50
<xdrazen>
:facepalm:
07:50
yes yes! i forgotted that
07:51
<alkisg>
There's irclogs.ltsp.org if you want to remember the conversation
07:51
<xdrazen>
well, i messed that. i will must to download the ubuntu 12.04.1 again
07:51
<alkisg>
You can install with 12.04.5 and then downgrade
07:51
If your internet is expensive
07:52
You'll need help to downgrade though, it's a bit harder then upgrades
07:52
<xdrazen>
alkisg
07:52
i really need your "council" i am not sure about what word is
07:52
<alkisg>
advice, ok
07:52
<xdrazen>
kinda a suggestion
07:52
<alkisg>
You now have wheezy?
07:52
Or ubuntu?
07:53
Anyway ok go on, ask what you want...
07:53
<xdrazen>
NOW NOW, i am with wheezy
07:53
but i wanna ask you
07:54
what could be the best way for do this. The server is a fx-8350 with its gigabit interface, the switch is a gigabit now

most of pentium pro has a scsi hdd
07:55
<alkisg>
xdrazen: we talked about it 3 days ago, and I adviced you to install 12.04.1
07:56
My opinion hasn't changed
07:56
<xdrazen>
thanks a lot. that is what i will do
07:56
<alkisg>
huafu: this is the vnc command:

07:59
<xdrazen>
what is the difference between ubuntu 12.04.5 and 12.04.1? the linux kernel?
07:59
<alkisg>
linux kernel and xorg version
08:00
You need the older xorg
08:00
You can install with 12.04.5 and downgrade
08:00
<xdrazen>
must i downgrade the linux kernel or the xorg?
08:01
<alkisg>
huafu: you don't have 192.168.67.1
08:01
We have code for automatic NAT on that subnet
08:01
Is there any reason why you want not to try the default setup?
08:02
<huafu>
I have another network in another room with the same 67, I just don't want to confuse myself
08:03
is it possible for me to change later back to 42?
08:03
<alkisg>
huafu: and that point, the real client gets an ip and the VM doesn't?
08:04
<huafu>
the real client (does not get an ip, it is stuck on trying to get one on the pxe boot)
08:04
<alkisg>
xdrazen: mainly xorg
08:05
huafu: what's the output of ipconfig on the server now/
08:05
?
08:05
<huafu>
it sounds like the server (vn guest) is giving one, but it looks like the packet or whatever isn't going back to the real client
08:05
server, ie the host?
08:05
<alkisg>
yes

<alkisg>
sorry, I should have said host, with 2 servers now it's confusing
08:06
<huafu>
confusing for me too, can I paste here?
08:06
<alkisg>
Sure

btw... i wonder, if i use the edubuntu 14.04.3 and downgrade the xorg. Could it work?
08:09

08:09

alkisg, IP-Config: eth1 hardware address 90:f6:52:03:9b:58 mtu 1500 DHCP RARP

and then it hand

hangs

<alkisg>
xdrazen: You can put newer graphics cards to your clients if you have. Or you can work with them as vesa, they'll be slower though
08:10
huafu: I don't see a request in the logs, but maybe it's because it's the same nic
08:10
<xdrazen>
i got some issues with vesa, the monitors were kinda strange, like a high frequency
08:10
<alkisg>
xdrazen: Do you have a standalone ubuntu client, or live cd, to run that ipconfig command from?
08:10
xdrazen: then just install 12.04, why do you resist so much?
08:11

08:12
<huafu>
alkisg, I have a mac I could do
08:14
<xdrazen>
well, this is pretty hard, it was not that i was "resisting"
08:14
<huafu>
alkisg, actually, I can't find my adapter to plug on the LAN, lemme try to find a machinw which would boot on usb
08:15
<alkisg>
xdrazen: it takes 1 hour to install ltsp-pnp, and you said you'd do it 3 days ago. Since then you installed, removed, installed wheezy, now you're asking the same questions again... it's a bit tiresome :)
08:15
<xdrazen>
i readed the wiki of ubuntu pnp
08:16
**(not sure, i guess that is "have read")
08:16
<alkisg>
The questions you ask now about the kernel and xorg, we talked about them 3 days ago again
08:16
You're asking the same questions now again
08:16
The advice you asked, I gave it to you 3 days ago
08:16
The specs, I asked for them 3 days ago and we talked about them
08:17
Anyway, just go on with the installation and ask if you have any issues following the page
08:20
<xdrazen>
thanks for be so patient. Right now, i will read the 3 days ago chat.
08:21
<alkisg>
Instead of reading, I advice that you install by following the page
08:22
<xdrazen>
http://old-releases.ubuntu.com/releases/12.04.1/ubuntu-12.04.1-desktop-i386.iso
08:22
this one i should download?
08:22
http://old-releases.ubuntu.com/releases/12.04.1/ubuntu-12.04.1-alternate-i386.iso
08:23
or better that one'
08:23
<alkisg>
Which 12.05.1 .iso did you download?
08:24
<xdrazen>
none of them. I got the mistake of download the 12.04.5 desktop i386
08:24
then i will download the other one
08:25
then, what is better? the desktop or the alternate?
08:25
<alkisg>
Sorry I mistyped, I meant "which 12.04.5 .iso did you download"
08:25
<huafu>
alkisg, ok found one lol, noe the command is running on it
08:25
<alkisg>
Install with the 12.04.5 iso that you already have
08:25
huafu: I closed the vnc window, can you open it again?
08:25
<huafu>
sure
08:26
<alkisg>
xdrazen: so, start with installing 12.04.5-desktop.iso
08:26
<xdrazen>
ok
08:26
i am on it
08:29
well, i will need further instructions. Eventually i could mess the internet (huawei e303 modem) wich was pretty funny to install
08:29
<alkisg>
huafu: maybe the promiscuus mode isn't working good enough for you. Can you temporarily try to change the bridged network to the internal network? I.e. with eth1=internal, and a vm client?
08:30
<xdrazen>
once installled the ubuntu 12.04.5 then should i "downgrade" the xorg?
08:30
<huafu>
alkisg, ok
08:30
<alkisg>
xdrazen: where will you be installing 12.04.5? in the pc what you are in irc now?
08:31
<xdrazen>
9
08:31
actua,
08:31
**actually, yes, for "try"
08:32
or i had better to have the fx 8350 server instead?=
08:32
<alkisg>
And now there you have wheezy and you have the modem installed?
08:32
Whatever is easier for you
08:34
<xdrazen>
i have the wheezy and the modem installed in the e1 laptop.
08:34
<alkisg>
Then install ubuntu on the 8350 server
08:37
<xdrazen>
ok. Then. once installed the 12.04.5 the next step will be downgrade the xorg?
08:39
<alkisg>
Yes
08:40
sudo apt-get install --purge xserver-xorg xorg
08:46
<huafu>
alkisg, so with the int network and another vm as the client I can't copy the output of the command but it seems to work, I see the pxe boot folder etc.., and the command actually does not hang
08:47
<alkisg>
huafu: then it's a problem with the promiscuus mode of vbox, try asking in #vbox
08:47
<huafu>
so I think it is a bug (?) with the promiscuous mode of vbox :/
08:47
haha
08:47
ok thanks
08:53
<xdrazen>
then. I am on
08:54
searching how to downgrade the xorg. When xorg would be downgraded, then
08:54
https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
08:58
<alkisg>
xdrazen: I wrote the command for you above, read it
08:58
(10:37:51 πμ) xdrazen: ok. Then. once installed the 12.04.5 the next step will be downgrade the xorg?
08:58
(10:39:38 πμ) alkisg: Yes
08:58
(10:40:22 πμ) alkisg: sudo apt-get install --purge xserver-xorg xorg
09:00
<xdrazen>
well. I am on it. I will be back here if any issue appears
09:01
1 install 12.04.5 2 downgrade xorg 3 https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
09:01
<huafu>
alkisg, waiting for an answer from there (#vbox) I am going to try the virtio-net adapter of vbox

09:13
<huafu>
alkisg, same issue, maybe I can put the dhcp server on the host as well as nat rule (I meant, I will need one then) and use the proxy config of dnsmasq?
09:13
...in the guest
09:13
<alkisg>
huafu: you don't need a proxy if you have a real dhcp
09:14
Just set up dhcp on the host so that it points to the VM
09:14lbssousa has joined IRC (lbssousa!~laercio@177.143.31.115)
09:14
<huafu>
alkisg, point to the VM?
09:15
<alkisg>
next-server==ip of VM
09:15
DHCP on the host, TFTP on the VM
09:15
You don't need proxydhcp at all
09:15
<huafu>
alkisg, ok thanks
09:15
alkisg, yeah that is what I want to do about dhcp on server and tftp on guest
09:15
arg, s/server/host
09:16
alkisg, should I still use dnsmaq instead of isc on the host? or does it then doesn't matter?
09:17
<alkisg>
The host doesn't have anything related to ltsp, right?
09:18
<xdrazen>
well, it is time for sleep 1 hour
09:18
as i told. I will do the things that i said before
09:18
<alkisg>
xdrazen: good night!
09:18
<huafu>
alkisg, nope, will just have the dhcp server now
09:19
the host is very very basic, I wanted to keep it free of cpu use and mem use, I'll even disable x from starting at boot later when all good
09:19
<alkisg>
Then sure use whatever you want, ltsp-config won't help you if you don't have it installed there
09:20
Why do you need a host + vm?
09:20
Why not just install the ltsp server in the host/

alkisg, I want to have a host clean, where I do not install anything, and on it have one ltsp server, maybe play with another one later which i could put in cluster (and later with a real machine), also another being the same but with windows instead of linux (but yeah, all those for later)
09:21
alkisg, also the goal is to easily rollback the crap I do, play with different config and backup them, etc..
09:22
alkisg, "why not install on the host", well I really want to keep the host as light as possible, with minimal services
09:22
<alkisg>
The lightest way is to have 1 host instead of 1 host and 1 vm
09:23
It saves ram, cpu etc
09:23
But if you want to do experiments and not production deployment, then sure vbox is fine
09:26
<huafu>
alkisg, yes I know it'll be lighter with one host and no vm system, but yeah I need to experiment and also have some kinda staging setup on VMs which I can later move "easily" on real new machines when I can buy them :D
09:27* alkisg is using his real system for experiments and has VMs for templates
09:28
<alkisg>
To test the VM servers, I'm using internal networking
09:28
<huafu>
alkisg, I have only one server, once I'll open the cyber, it'll not be ok to fuck up that system lol
09:28
alkisg, so in the guest then I have to set eth1 to dhcp right?
09:29
<alkisg>
No, set up a static ip
09:30
Also if you want to be able to ship template servers, use network manager, it's easier for the users to see the network settings, the speed, if the cable is disconnected etc from the indicator in the tray
09:32
<huafu>
alkisg, I don't want the user to change anything or see anything lol, also I could change to managed=true in the [ifdown] section of NetworkManager.conf
09:33
alkisg, can't I setup it to dhcp and assign the vm a static lease thru the host isc config?
09:33
<alkisg>
sure
09:33
<huafu>
alkisg, or it MUST be static for some reason?
09:33
ok thx
09:33
<alkisg>
no

alkisg, sorry my irc client crashes I suppose
09:58
<alkisg>
No worries
10:27
<huafu_>
alkisg, it looks like the promiscuous mode or something makes it fail the same the other way around, can't get an ip from the host on the guest, I see the dhcp request but the guest is not taking any ip
10:27
<alkisg>
huafu_: I thought you now had a real host and a real client?
10:28
And the vm is the ltsp server?
10:28
<huafu_>
yup
10:28
<alkisg>
So where is the promiscuous mode involved now? No VMs...
10:28
<huafu_>
I think it doesn't like that the dhcp server and client are on the same real NIC
10:28
alkisg, well I do not know what is wrong, but i can't get an ip with dhcp on the vm. I'll fix it
10:29
<alkisg>
Aaah you mean the dhcp request for the ltsp server, not for the ltsp client
10:29
Yes it's quite possible that dhcp broadcasts don't show up on the same nic
10:30
<huafu_>
alkisg, I have to set address, netmask and gateway right? no more?
10:31
<alkisg>
For a static ip? yup
10:32

alkisg, oh man I can't ping anything :/

14:25
anyway, thanks for all the huge help lately
14:36
work_alkisg, also having issues on using 2 languages, sounds like you can only see and use the language defined system wide, impossible to change, and also impossible to type the password of a user in a console after login :/
14:51
work_alkisg, also you talked about caching the kernel on the clients which have some disk, is that "easy", can't find any tuto on the web

15:01
<alkisg>
That's about it, no tutorials needed
15:02
About using a different language, yup it's possible, I don't know what issue you have there
15:06
<huafu>
alkisg, thanks - I've fixed the nat already
15:07
for languages, I need to have thai as first main language, but still have the ability to change the input method and change the language to english
15:08
I tried many configuration, setting the locale in lts.conf, changing it before loging in, after (this is not even possible), but it all ends up in NOT changing anything, and the language to remain in the main (/etc/default/locale) language
15:08
<alkisg>
Are you using ltsp-pnp or plain chroot?
15:08
<huafu>
I did install all lang packs, installed all `check-language-support`, etc...
15:09
pnp
15:09
<alkisg>
thin clients or fat?
15:09
<huafu>
I striclty followed pnp this time, except again for the IP range
15:09
fat clients
15:09
<alkisg>
what's the output of env | grep ^L, on the server (where things work) and on a client?
15:10
<huafu>
I yet did not test in thin, but I do remember last time I had some issues with the language too, and switching to non pnp and including all required packages in the chroot fixewd it, but well, not sure I hadn't other issues with the pnp as it could be the case now
15:10
<alkisg>
LTSP_FATCLIENT=False gives you thin
15:10
You don't need another chroot
15:11
<huafu>
I am not doing any chroot since I am in pnp mode, but I'll need a chroot because my thin clients are raspberries (another arch)
15:11
but well, thin/fat isn't the issue here, my issue is with first fat client tested (for now :D)
15:11
where can I put the output of this command? it's kinda big
15:13
<alkisg>
paste.debian.net
15:13
or just omit the variables that are not related to lang, lc_all etc
15:14
<huafu>
alkisg, I used pastebin, dunno why I did not think about it earlier
15:14
http://pastebin.com/57hha1Tk
15:14
weird it does not fully match /etc/default/locale
15:14
<alkisg>
You have half thai settings and half english
15:15
Usually setting LANG and LANGUAGE are enough, the rest are not needed
15:15
If you manually set them, then you should be setting all of them, not half
15:15
Where are you setting all these from? .profile?
15:15
Finally... don't login graphically as root :)
15:16
<huafu>
no, I just set in /etc/default/locale - ah, and then to try to fix in VMs I changed in the gnome settings and "apply system wide"
15:16
the one I gave you is root on the server only
15:17
<alkisg>
The normal way is:
15:17
1) install ubuntu with the locale you want
15:17
2) set LANG in lts.conf or select a language in LDM
15:17
(2 == to override the system defaults)
15:18
3) Don't use the ubuntu or gnome ways to set the locale, they're broken :D
15:18
<huafu>
ah ok, so how I can reset the 3?
15:18
<alkisg>
xorg was working fine for ages and then gnome and ubuntu decided to break everything in 10 different ways
15:18
<huafu>
haha
15:18
<alkisg>
$ cat /etc/default/locale
15:18
LANG="el_GR.UTF-8"
15:18
That's all that should go there
15:19
$ cat /etc/environment
15:19
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
15:19
<huafu>
oh, and what about l10n?
15:19
<alkisg>
And that's environment in case you changed it
15:19
<huafu>
no I did not change env
15:19
<alkisg>
l10n? you've installed language-packs, didn't you?
15:19
By setting LANG, you get the locale you want
15:20
<huafu>
I meant, I need enmglish langauge, thai setup for currency, and european dates (not *** american dates with the month before the day)
15:20
<alkisg>
Then do set LC_MONETARY and whatever else you want to be static
15:21
<huafu>
because thai dates are... in thai :D and I yet did not finish to learn the whole alphabet consisting of 44 consonents and 33 voewls :D
15:21
<alkisg>
Don't set LC_ALL though if you don't want it to apply for everything
15:21
<huafu>
ok
15:21
thanks will try that
15:21
<alkisg>
Woah, thai children must start talking after 5 years old with all those letters... :D
15:22
man locale ==> gives you the variables involved
15:22
<huafu>
alkisg, you meant writing, well actually not, but they learn faster than me
15:22
<alkisg>
No I meant speaking, with so many different letters it must be difficult
15:23
<huafu>
alkisg, sorry, so I can set en_US.UTF-8 in /etc/default/locale, and then change the LANG in lts.conf so that ltsp client would be in thai by default, but able to change it?
15:23
<alkisg>
Greek vowels are very few and easy, I had a hard time learning the english ones with all the subtle variations
15:23
Yup
15:23
Set LANG and LC_MONETARY etc there, in default/locale
15:23
But not LANGUAGE or LC_ALL

<alkisg>
Haha, that's true :)
15:25

:p ok setting up as you told me now ;-)
15:25
btw, where does gnome put some crap when I changed the language of my session, so that i can revert that?
15:27
<alkisg>
in 10 different places :(
15:27
accountsettings, .dmrc, gsettings...
15:27
<huafu>
ok will search on google
15:27
:/
15:28
rm -rf .gnome .gnome2 .gconf .gconfd .metacity .cache .dbus .dmrc .mission-control .thumbnails ~/.config/dconf/user ~.compiz*
15:28
:D
15:29

15:29
and dconf is in .local (or in .config, don't remember)

(ltsp-update-image --cleanup /)
15:35
<alkisg>
The /opt/ltsp/images/i386.img contains a copy of your server disk
15:36
You don't want your password there exposed to the network via nbd, do you?
15:36
cleanup removes the passwords, users, ssh keys etc before the compression
15:36
<huafu>
alkisg, sorry, a question about this too, it is a copy of the ENTIRE server disk, or just some part of it?
15:36
ah cool! thanks

you can't easily reset accountservice settings by just deleting files
15:40
try rebooting and logging it with a guest user first, to verify that you've correctly set the system defaults

ok, I'll go to runlevel 3 and cleanup crap right?

reformat :)

15:46
<huafu_>
actually it's exactly what it showed me when I tried to login to my user from the ltsp client
15:47
ah no man I can't reformat seriousely, last time was because I needed to move from a server amd64 distro to a desktop i386
15:47
I reformat so many times lately that I feel like using windows
15:47
well, just 3 times, but each was because of a distro change
15:48
now I am on the basic ubuntu desktop i386 and I want to fix this

I guess I can delete my user account :/
15:48
ah no rrr

it's not about it

i'm sure this is also partially related, but clients also can't eject the drive. it gives the good ol 'not in the fstab (and you are not root)

thin clients
16:40
running lxde
16:41
<alkisg>
thin clients are using ltspfs, they're not mounting usb devices normally
16:41
you can just unplug the devices after 2 seconds of inactivity
16:41
if your clients have enough cpu/ram, you can make them ltsp fat clients instead.
16:41
<m3741>
ah, ok
16:43
how does ltspfs handle permissions?
16:43
<alkisg>
what file system does the usb stick have? fat or ext?
16:45

i have one drive that has two partition on it, one exfat, one ext4. another is ntfs
16:46

can linux write to exfat?

or read it?

my ubuntu 14.04 x64 desktop seems to do ok.

Try with simpler things first, does it read/write to e.g. a fat or ext4 stick that only has 1 partition?

huafu: if you're using lts.conf in a tftp directory, you don't need to re-run ltsp-update-image.
19:03
<huafu>
vagrantc, thanks, that also if my lts.conf is in tftp root BUT symlinked from another path out of tftp?
19:04
:/ ok answering myself, yes I am stupid haha

<huafu>
where should I configure specific graphic drivers and configuration for each client, knowing that I am using a pnp ltsp server?
19:19
<vagrantc>
huafu: it depends on your tftp server and config weather it supports symlinks
19:19
huafu: it should autodetect the appropriate drivers
19:19
huafu: and there are lts.conf settings if it doesn't
19:19
!lts.conf
19:19
<ltsp`>
lts.conf: (#1) http://manpages.ubuntu.com/lts.conf, or (#2) lts.conf manpage is available in the ltsp-docs package
19:20
<huafu>
vagrantc, thanks again - for the drivers, I am asking because I have very bad and buggy graphics on one of my fat client (card is 82865G)
19:20
ok, will look again in lts, thanks
19:20
<vagrantc>
intel?
19:21
<huafu>
yup sorry
19:23
<vagrantc>
if it doesn't autodetect correctly ... it gets complicated fast
19:23
<huafu>
vagrantc, VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)
19:23
<vagrantc>
sometimes there are simple workarounds...
19:24
depends on exactly what you need to change
19:24
<huafu>
vagrantc, I do have graphics, but sounds like 16 bit colors or less
19:24
vagrantc, I do not want to change anything, just do the right thing so that it display things correctly
19:24
<vagrantc>
on a fat client, or thin client?
19:24
<huafu>
fat
19:25
<vagrantc>
you could try forcing X_COLOR_DEPTH=24 for that client
19:25
<huafu>
it's not only the colors, lemme show you
19:26
<vagrantc>
it's probaly got issues with kerenl mode setting ... those are a pain to debug
19:26
huafu: what distro?
19:27
and version
19:27
<huafu>
xubuntu 14.04.3
19:27
i386
19:28
<vagrantc>
i seem to recall they were fixed in debian ... should be fixed in ubuntu 14.04 ... if not, it may be really challenging to get working
19:29
<huafu>
:/
19:29
where should I look? do you have any link which could help?
19:29
<vagrantc>
it's been so long since i messed with those issues
19:29
you could try an older version of ubuntu for those clients
19:29
or debian, etc...
19:29
<alkisg>
post your xorg.7.log to pastebin

thanks ;)
19:31
hu, cant get it full
19:31
<alkisg>
(from the client, /var/log/Xorg.7.log)
19:31
scp
19:31
or open firefox from the client
19:31
<huafu>
ah yeah, sorry it's 2.30am here, can't even think straight lol

19:40
<huafu>
ok the graphic card is ok
19:40
I am too tired
19:40
<alkisg>
It's the monitor?
19:40
<huafu>
but... is it xubuntu having a dirty background with some black in the middle as a joke?
19:41
<alkisg>
Hahaha
19:41
<huafu>
nope, everything is fine except the background, which I did not change and on the server it looks ok
19:41
<alkisg>
It's possible that the first background is painted wrong
19:41
<huafu>
alkisg, it's possible to fix that possibility? :D
19:41
<Hyperbyte>
huafu, possibly.
19:41
<huafu>
:D
19:42
<alkisg>
Haha
19:42
if you logout/login again, does it work on the second (or third) try?
19:42
<huafu>
I'll try now
19:49
ok just the second login did work
19:50
alkisg, btw I have to find a way to limit my users to <=480 youtube videos, as well as using more bandwidth, it is slowing down the clients (fat) because.... they are old machines
19:51
alkisg, ah, I had one question for you ltsp guru, would I gain in performances (after the client has logged in) if I do cache the kernel on the hdd of the fat clients?
19:51
<alkisg>
Issues like this are not related to ltsp, but do also try chromium-browser and/or google-chrome, those have a much newer flash version which performs better
19:52
Do you have gigabit now?
19:53
<huafu>
alkisg, no, I do not even had money to pay my internet lol, I am still awaiting for my salary lol
19:53
<alkisg>
About the background issue, I think LDM does something wicked with the background and breaks the DE background on some cases
19:53
Then it will make it faster, yes
19:53
E.g. launching libreoffice needs 120 MB of bandwidth
19:54
That's 12 seconds for 100 mbps for a single client
19:54
<huafu>
but caching the kernel will not include libreoffice
19:54
<alkisg>
Or 120 seconds for 10 clients
19:54
<huafu>
or does it?
19:54
<alkisg>
I thought you meant this:
19:54
!local-boot
19:54
<ltsp`>
local-boot: If you want LTSP fat clients on a low-speed network, you can put i386.img on e.g. C:\Boot\LTSP\i386.img and use this command line in pxelinux.cfg: APPEND ro initrd=ltsp/i386/initrd.img init=/sbin/init-ltsp root=/dev/sda1 rootflags=ro loop=/Boot/LTSP/i386.img; IPAPPEND 3
19:54
<alkisg>
The one you were asking about before
19:54
<huafu>
oh, I forgot the .img contains the whole disk haha
19:54
yup I meant that
19:55
<alkisg>
So, 120 MB for a normal disk is usually under 5 secs
19:55
<huafu>
ok so yeah it'll be faster, but once firefox is launched then it doesn't change a thing right?
19:55
<alkisg>
i.e. much better than reading it from the network
19:55
Well, yes, but...
19:55
suppose firefox needs to write to home
19:55
And the other 9 users are just launching firefox or libreoffice
19:56
<huafu>
haha
19:56
<alkisg>
==> network saturated, firefox can't write to /home fast enough
19:56
So it helps there too
19:56
<huafu>
and in the case I use local boot, is there a way to automate the update of the local image in case it has changed somehow?
19:57
<alkisg>
You can implement it with a small script, sure
19:57
Write it as a bounty if you want, maybe someone will sponsor it (I know you can't)
19:57
!bounties
19:57
<ltsp`>
bounties: You can ask an LTSP developer to implement new features or fix hard bugs by offering a bounty: http://wiki.ltsp.org/wiki/Bounties
19:57
<alkisg>
I think the best way there is to let the user work with the old image, while syncing the new one
19:58
And it would be nice if we overlayed 2 nbd images, one big one and a small one for .diffs from the previous big one
19:59
<huafu>
yup, syncing while it's running, also improvements can be adding resume and such :D
19:59
<alkisg>
rsync resumes
19:59
<huafu>
wow, that is too much for me to do :) so yeah bounty
20:00
alkisg, if you come to thailand I offer you a beer, there is no bounty here :D
20:01
rsync resume ok, but incremental... not something I'll try to do (at least in the near future)
20:01
anyway, I am first going to do a chroot for my raspberry
20:02
ah, yeah alkisg I must do a chroot and can't do pnp for RPis right?
20:02
<alkisg>
You can do pnp on an rpi
20:02
<huafu>
oh
20:02
<alkisg>
but ltsp-update-image really sucks on rpis :D
20:02
Do the chroot method
20:02
My daughter wanted to come to thailand very much
20:03
<huafu>
well very touritsic area is not very nice, it's not the real thailand, it's the touristic crapy one
20:04
but you have very nice spots all around big cities or even farer if you like country side
20:04
<alkisg>
Haha OK we'll come there to fix your ltsp setups and you give us a tour of the real thailand :D
20:04
<huafu>
haha sure :p
20:06
<elias_a>
huafu, alkisg: This fake tourist area problem is all over the world.
20:06
<huafu>
elias_a, yeah sure, but here it's really like black and white
20:06
<elias_a>
Also here in Finland very odd things are marketed to tourists.
20:06
huafu: I know :(
20:07
<huafu>
elias_a, I travelled a lot but yet not go to thailand
20:07
arg, to finland lol
20:07
but I know "kipis" tho I am not sure how to write it ;-)
20:08
<elias_a>
huafu: Finland is far away. :) Land's end, really.
20:08
huafu: Wow. Kippis!
20:08
<huafu>
elias_a, I am from france so it used to be not so far - also I like the cold (yeah wtf am I doing in thailand you can say)
20:09
I used to know Kippis in greek but can't remember, tho I went to greece lol
20:09
anyway, ltsp-image-build --arch thailand
20:09
<elias_a>
huafu: Ok. I do understand why ppl move to Thailand. Nice climate is always... nice. ;-)

20:13

elias_a, well I live with my familly here, moving 3 children still at school and in need of complex visas is not some task I am going to do soon :)
20:14
elias_a, also I love the people here, the poorer they are, the happiest they are and the more they want to help you
20:29
alkisg, when you were talking about chrome, I never know what is the one to install, chromion or google-chrome or another one?

20:37
<alkisg>
Chromium-browser is the open source equivalent of google-chrome
20:37
Try that first if it works OK for you, otherwise google-chrome might have some non-free decoders that will work better
20:37
flash should be the same though
20:40
<huafu>
I use to have a lot of issues with chromium that is why I am asking
20:41
<alkisg>
I'm using firefox except for a few cases where google-chrome shows videos a bit better
20:46
<huafu>
I am going to do some benchmarks and use the one that runs faster
20:47
once all is good I will need to do a lot of more work as setting up the template user
20:47
its menus, etc...

does anyone knows if a section in lts.conf can have multiple `LIKE=`? and if it can cascade multiple sections, as: [SECTION1] LIKE=SECTION0 ... [SECTION2] LIKE=SECTION1 ...?
22:22
<vagrantc>
experiment to find out :)
22:22
<huafu>
I have very slow machines ;-)
22:23
<vagrantc>
even for a machine that takes 2 minutes to boot, and you have to boot it 5 times, it's probably still fairly quick to test numerous permutations ... especially if you boot multiple machines at the same time
22:26
<huafu>
warren, well I was asking here in case someone had the answer, because it's 5am and it's already hard for me to type, so walk here and there to one and another machine, and also make my stupid brain think about how to implement this test (yes it's easy but not for me right now :p)
22:26
I guess I'll just test and then copy paste lol
