| 00:14 | <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

| 02:03 | <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

| |
| 03:09 | <major_ghz> ok
| |
| 03:11 | a very thank, now i think i have all i need
