<major_ghz>
hello
00:15
i try to use ltsp in my lan
00:15
but when client connect i have ARP time out
00:17
<vagrantc>
when it's trying to boot?
00:18
<major_ghz>
i have dhcp ip, but arp time is when tftp search image i supose
00:19
i have /srv/tftp umpty
00:20
empty*
00:21
vagrantc, i use lan boot
00:21
<vagrantc>
is it on a network with a router?
00:21
or is it a network with only your ltsp server and your thin client?
00:22
<major_ghz>
no by router
00:22
<vagrantc>
multiple DHCP servers could cause it to respond to the wrong one
00:22
<major_ghz>
need stop router dhcp deamon ?
00:23
<vagrantc>
depends on how you set it up
00:23
!proxydhcp
00:23
<ltsp_>
proxydhcp: A proxy DHCP server is defined by the PXE specification as a server which sends auxiliary boot information to clients, like the boot filename, tftp server or rootpath, but leaves the task of IP leasing to the normal DHCP server. More info: https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
00:23
<vagrantc>
major_ghz: the instructions for proxydhcp should work
00:23
as long as there are not other network boot servers on your network
00:23
<major_ghz>
no
00:24
but i am not install proxydhcp
00:25
just udhcpd
00:26
ubuntultsp is an easy distrib for use ltsp ?
00:28
i am not environment for client on my server...
00:30
certenly that is the bug, i think ltsp-build-client need use on the client
00:32
bug between keyboard and chair
00:33
oups, ltsp-build-client install amd64 packages
00:33
the client is i386
00:33
how i specify x86 architecture ?
00:35
ltsp-build-client \
00:35
--arch i386
00:36
in the futur, how can i try ltsp under a wan ?
00:55
can use a ltsp serveur under a minimal system ? not pass by boot lan but start in local a minimal system and use ltsp after ?
00:56
like to use the ltsp system by wifi peraps
00:56
<gdi2k__>
major_ghz, I saw this the other day, which may help: http://labs.opinsys.com/blog/2014/01/31/how-to-boot-ltsp-client-from-harddrive-using-grub/
00:56
I don't think the experience will be good over wifi though - too slow
00:58
I use the proxydhcp method and it works fine alongside an existing DHCP server - definitely would go that route if possible so you don't have to worry about local media in the clients
00:58
<major_ghz>
how many mb/s need for a correct use ?
00:59
<gdi2k__>
fat or thing clients?
00:59
<vagrantc>
it's not just MB/s, it's also latency
00:59
over a WAN is too high latency
00:59
over WIFI is too likely to have traffic congestion
01:00
<major_ghz>
no method like ltsp exist for a wan use ?
01:01
<vagrantc>
depends on what you mean by "like ltsp"
01:01
LTSP is really just about network booting
01:01
<gdi2k__>
I use x2go to remote into machines - works great - but it assumes you have a full working machine on the client side. x2go is like RDP
01:02
<major_ghz>
x2go ?
01:03
<gdi2k__>
http://wiki.x2go.org/doku.php
01:04
you could boot a machine from USB stick using a thin client distro that included something like x2go, then just remote into the server across the WAN - it is specifically designed for WAN. LTSP is not suitable for WAWN
01:04
<vagrantc>
x2go using something derived from the NX protocols?
01:04
<gdi2k__>
yes
01:04
<major_ghz>
ok, x2go can use under wan ? is that i need, not ltsp
01:04
<gdi2k__>
ok
01:05
look at thinstation or open thin client
01:05
that will get your client booted and ready to connect via x2go or even RDP (for windows)
01:07
<vagrantc>
i should look into x2go client support for ltsp...
01:08
<gdi2k__>
:)
01:11
<major_ghz>
thank gdi2k__
01:11
<gdi2k__>
np
01:14
<major_ghz>
x2goclient need install on the server or on the client ?
01:19
<vagrantc>
x2goclient on the client, i think ... no idea what to install on the server.
01:24
<gdi2k__>
there are server and client components
01:24
<major_ghz>
ltsp-build-client need install on server, it's for that
01:25
<gdi2k__>
you don't need anything ltsp if all the clients are going to connect over WAN
01:26
just install a regular Ubuntu Desktop (I prefer Xubuntu myself) on the server. Then install the x2go server on the server (use the PPA).
01:26
on the client side, you can use any regular Linux desktop and install the x2go client
01:27
or you can have a minimal system that just starts up only the x2go client and lets people log straight into the server
01:27
<major_ghz>
ok
01:27
need a normal xubuntu ?
01:27
<gdi2k__>
yes
01:28
<major_ghz>
can't install on a vps server ?
01:28
<gdi2k__>
you could, no reason why not, assuming you can get IPMI / VNC access to install it properly
01:28
<major_ghz>
absoluty need a X session ?
01:29
<gdi2k__>
X is required
01:29
it's part of Xubuntu
01:29
<major_ghz>
but how can start X on a serveur, without screen ?
01:29
i test x2go on my at home, but no X
01:30
package install but no run
01:30
<gdi2k__>
well, X is sent over the WAN to your client. When you log in with x2go, it starts are regular desktop session and the output is sent to the x2go client over the wan
01:31
I will make a screencast so you can better understand...
01:31
<major_ghz>
ok x2godesktopsharing is not need use for complet desktop ?
01:35
<gdi2k__>
not sure what that is, but you just need x2go client on the client and x2go server on the server. on ubuntu and similar you can just use the PPA to get the latest packages
01:35
<major_ghz>
La clef d'hôte pour ce serveur n'a pas été trouvée mais un autre type de clef a été trouvé. Un attaquant peut avoir changé la clef par défaut du serveur pour faire croire à votre client que la clef n'existe pas
01:36
<gdi2k__>
http://wiki.x2go.org/doku.php/wiki:repositories:ubuntu
01:36
<major_ghz>
sorry this message is in fr
01:37
<gdi2k__>
ah ok
01:37
yes
01:37
see http://john.wesorick.com/2011/11/issues-installing-x2go.html
01:38
"This will happen if you SSH into the server before installing x2go. SSH by default likes ecdsa keys, and x2go doesn't. "
01:40
looks like this: http://ge.tt/4Le7b8K1/v/0
01:43
<major_ghz>
ok see
01:43
but i don't fine the line need comment un ssh_config
01:45
<gdi2k__>
you don't see "HostKey /etc/ssh/ssh_host_ecdsa_key" ?
01:46
I have it in mine quite close to the top of the file (recent Xubuntu)
01:46
<major_ghz>
i have /etc/ssh/ssh_host_ecdsa_key
01:47
but no ligne start by HostKey in ssh_config
01:48
<gdi2k__>
on the server
01:48
it is sshd_config
01:48
not ssh_config
01:48
(server side)
01:48
<major_ghz>
ah ok
01:49
no sshd_config
01:49
<gdi2k__>
on the server? you have ssh installed?
01:49
if not, sudo apt-get install openssh-server
01:50
then modify sshd_config before attempting to connect with x2go
01:50
<major_ghz>
i connect on the server by ssh
01:50
<gdi2k__>
you can test by doing (from terminal on server): ssh localhost
01:50
ah ok
01:51
<major_ghz>
but in /etc i have ssh and after ssl
01:51
no sshd
01:51
<gdi2k__>
/etc/ssh/sshd_config
01:51
that is the file
01:51
it is in ssh, but file is called sshd_config
01:52
<major_ghz>
ok i fine
01:52
need more sleeping
01:56
ok it's work better
01:56
just need install xfce4
01:56
<gdi2k__>
install xubuntu-desktop package
01:56
it installs everything you need for a xfce environment
01:56
(assuming this is ubuntu!)
01:57
<major_ghz>
can use x2goclient with a special host system for only use x2go ?
01:57
gdi2k__, i am on my at home server and i was install debian
01:57
<gdi2k__>
ok with debian not sure, but xfce would be a good start
01:58
then you have to manually install all the office apps / browsers etc.
01:58
but yes, you can have a client boot and automatically launch x2go client
01:58
so it is seamless
01:58
<major_ghz>
seamless ?
01:58
<gdi2k__>
(they are working on a x2go live cd but it is not finished)
01:58
seamless = as if logging into a local machine - user won't notice
01:59
performance across WAN will never be like local performance though - you should be aware of that
01:59
<major_ghz>
can use x2go live on usb disk ?
01:59
<gdi2k__>
it is not ready yet
01:59
but yes you would be able to
01:59
<major_ghz>
ah ok
01:59
<gdi2k__>
you can use thin station I think
02:00
<major_ghz>
yes for thin station
02:00
<gdi2k__>
you can put it on a USB flash drive

<administrateur>
hello it's major
02:04
i am connect on my at home :)
02:04
it's work fine
02:04
<gdi2k__>
morning Major!
02:04
lol
02:04
good
02:04
<administrateur>
ok now need to fine a solution for only x2goclient use by my friends
02:05
like is os is in his machine
02:06
may be is night, it's 3h am in france :)
02:06
<gdi2k__>
sleep first ;)
02:06
in the morning it will be clear
02:08
<administrateur>
ok, it's possible tu install a lighty xubuntu, by deboostrap or else for only use x2go, like the desktop is her marchine ?
02:08
<gdi2k__>
yes, that may be overkill - look at minimal distros
02:08
x2go client actually uses qt
02:08
so no need for gnome or xfce stuff on the client even
02:09
I would start with minimal debian install or alternate ubuntu install
02:09
(ubuntu server even - then just install what you need)
02:09
<administrateur>
alternate ubuntu install is good
02:10
but how can i start into lightdm and after connect on my server ?
02:10
<gdi2k__>
you can just startx I think
02:11
google for "Linux kiosk mode"
02:11
no need for login manager
02:11
<administrateur>
need very user friendly
02:15
http://www.alandmoore.com/blog/2011/11/05/creating-a-kiosk-with-linux-and-x11-2011-edition/
02:15
is that ?
02:40
ok return on my computer

02:56
<gdi2k__>
look at http://www.techpository.com/?page_id=1371 from step 20 onwards
02:56
they are using chromium browser, but you could use x2go
02:56
"nodm" lets you install xorg without any sort of desktop manager
02:57
major_ghz, see above
02:57
http://www.enricozini.org/sw/nodm/
03:09
<major_ghz>
ok
03:11

I just got an error on my new server: failed to load session ubuntu-2d. my guess, since it's an old login, is that it's trying to load a desktop that doesn't exist anymore, but I'm not sure where to make a change to fix it. thoughts?
