| 00:33 | <gdi2k_> ege, if you're still around, LTSP is best suited for the LAN. Try NX-based stuff for WAN. I use X2Go personally and it's easy to set up and works really well over LAN. You can google it

| 11:36 | <ege> Hi gdi2k_, thanks for your answer.
| |
| 11:36 | I found a lot NX stuff but that was all really old
| |
| 11:37 | I'll have a look at X2Go
| |
| 11:45 | thanks, looks promising and had a release last year and not only in 2008 like others :)

| 19:45 | <aruiz> hello there, I want to decouple the main dhcp/tftp LTSP server from the desktop provider, can I run ldm in one machine and the rest of the services in another one?
| |
| 19:47 | <vagrantc> the short answer is yes
| |
| 19:47 | * aruiz is afraid of the long answer now | |
| 19:47 | <vagrantc> on debian/ubuntu you want to install the ldm-server package on the server(s) you want to serve applications
| |
| 19:48 | <aruiz> vagrantc, how do I tell the clients the server is there?
| |
| 19:48 | <vagrantc> technically, ldm runs on the thin client :)
| |
| 19:48 | <aruiz> that's the bit I'm struggling with
| |
| 19:48 | <vagrantc> aruiz: set LDM_SERVER in lts.conf
| |
| 19:48 | you'll also need to get the ssh keys from the server moved over
| |
| 19:48 | <Hyperbyte> aruiz, out of curiosity... why do you want this?
| |
| 19:48 | * vagrantc has used that sort of setup for ages | |
| 19:49 | <vagrantc> with one LTSP server, you can have numerous application servers.
| |
| 19:49 | <aruiz> Hyperbyte, I want to split network services from the main desktop provider
| |
| 19:50 | <vagrantc> it also provides some measure of isolation ... the rootfs not being hosted on the same machine as the GUI apps, which have far more security vulnerabilities
| |
| 19:50 | <aruiz> Hyperbyte, it's not the first time I need to upgrade the desktop system but I don't want to because it may break the whole setup
| |
| 19:50 | so say, I need to chose between the latest LibreOffice and a reliable system
| |
| 19:50 | :-)
| |
| 19:50 | I don't want to make that choice
| |
| 19:50 | so for now I want to put all the network services (CUPS, DHCP, tftpboot, LTSP images) in a LXC container
| |
| 19:51 | it also helps when it comes to backing up the system
| |
| 19:51 | if the system crashes
| |
| 19:51 | I reinstall a vanilla ubuntu, deploy that LXC and everything is working and configured again
| |
| 19:51 | <Hyperbyte> Right, you want to move nbd too... then it makes more sense.
| |
| 19:51 | <aruiz> Hyperbyte, yeah
| |
| 19:51 | <Hyperbyte> I actually use virtual machines for this purpose. :)
| |
| 19:51 | <aruiz> basically the desktop should only serve... the desktop :-) (and ssh too of course)
| |
| 19:52 | Hyperbyte, I have a Windows VM too, but VMs have a lot of overhead compared to containers
| |
| 19:52 | <vagrantc> oh yes, i was assuming splitting all the non-desktop stuff to a separate server
| |
| 19:52 | <aruiz> VirtualBox is not 100% reliable in my experience, and I don't want a hybrid KVM+VBox setup :-)
| |
| 19:52 | <vagrantc> splitting tftp and rootfs is a pain.
| |
| 19:53 | <aruiz> vagrantc, na, I basically want everything LTSP in that container, but the desktop
| |
| 19:53 | <vagrantc> right, that's simple.
| |
| 19:53 | <Hyperbyte> I disagree actually. With kvm-qemu there's not so much overhead I think. At least I haven't ran into any problems running a full thin client server virtualized.
| |
| 19:53 | <aruiz> vagrantc, so installing ldm-server and setting LDM_SERVER should do the trick right?
| |
| 19:53 | <Hyperbyte> Anyway, different discussion... :-)
| |
| 19:54 | <vagrantc> aruiz: and copying the ssh keys to the LTSP server
| |
| 19:54 | <aruiz> vagrantc, the public ones?
| |
| 19:55 | <vagrantc> aruiz: the lazy insecure way is: ltsp-update-sshkeys --export SERVER > /etc/ltsp/ssh_known_hosts.SERVER
| |
| 19:55 | yes, the public keys
| |
| 19:55 | and then ltsp-update-sshkeys (and possibly ltsp-update-image, if you use NBD)
| |
| 19:56 | oh, wait.
| |
| 19:57 | ltsp-update-sshkeys --export /etc/ltsp/ssh_known_hosts.SERVER SERVER
| |
| 19:57 | or you could even leave out --export ...
| |
| 19:57 | i always did it manually
| |
| 19:58 | <aruiz> so wait... this is the bit I don't understand
| |
| 19:58 | <vagrantc> aruiz: you need the application server's public ssh host keys
| |
| 19:58 | <aruiz> I should run ltsp-update-sshkeys on the container (where the ltsp services are, except for the desktop)
| |
| 19:58 | but what do I do on the ldm-server?
| |
| 19:58 | right, but are those root ssh keys?
| |
| 19:58 | <vagrantc> you veryify that ltsp-update-sshkeys grabbed the right keys
| |
| 19:59 | <aruiz> or is this run by a particular user?
| |
| 19:59 | <vagrantc> ssh host keys
| |
| 19:59 | <aruiz> ah the host keys, gotcha
| |
| 19:59 | <vagrantc> you'll run it as root, yeah.
| |
| 19:59 | <aruiz> got it,
| |
| 19:59 | <vagrantc> it basically uses ssh-keyscan to download the keys from the server
| |
| 20:04 | aruiz: you can manually create them, you just copy the /etc/ssh/ssh_host*.pub into a file, and prepend each line with the server name.
| |
| 20:07 | you'll also need name resolution to work properly, or use "HOSTS_xx=appserver1 192.168.0.5"
