| 09:38 | <jgomila> hi again
| |
| 09:39 | i have a doubt about ltsp and openstack
| |
| 09:39 | <vagrantc> doubts are healthy
| |
| 09:40 | <jgomila> I have 5 offices with about 30 computers
| |
| 09:41 | I wish to migrate to opensource software, and I am thinking in a terminal server thin client
| |
| 09:41 | but I have seen the openstack project, its similar to ltsp ?
| |
| 09:42 | <vagrantc> entirely different things
| |
| 09:42 | openstack is a system of virtualized computers
| |
| 09:42 | ltsp is about network booting (usually physical) computers
| |
| 09:43 | openstack might be most useful in a datacenter ... ltsp might be most useful in a clasroom or office setting
| |
| 09:44 | <jgomila> then I need to search more info about ltsp implementation than openstack
| |
| 09:44 | <vagrantc> that said, you might be able to use openstack to run your LTSP server ... but using more simple virtualization would proably be a better starting point
| |
| 09:45 | basically, ltsp allows you to manage arbitrary numbers of desktop computers as if they were one computer
| |
| 09:45 | <jgomila> openstack should be useful if I wish install ltsp server in each office to reduce the latency loading the image from ltsp ¿no?
| |
| 09:45 | <vagrantc> i don't see why openstack in particular would be useful
| |
| 09:46 | virtualization is generally useful ... but openstack is one of the more complicated virtualization implementations
| |
| 09:46 | <jgomila> i am very new in this area, always worked with standalone computers
| |
| 09:47 | the ideal for our implementation should be ltsp servers in each office sharing data between them
| |
| 09:47 | and allow user mobility between offices
| |
| 09:48 | <vagrantc> ah, the offices aren't on the same local network?
| |
| 09:48 | <jgomila> i believe, I am not sure if its realiy needed
| |
| 09:48 | all the offices are connected via a private network over internet with cisco routers
| |
| 09:49 | 300mbps on the main office, but less in the other offices, both of them only adsl 10mbps
| |
| 09:49 | both = two
| |
| 09:49 | * vagrantc nods | |
| 09:50 | <vagrantc> yeah, probably want a server at each site ... syncing the homedirs between sites will take some custom work
| |
| 09:51 | nothign out of the box to support that
| |
| 09:51 | <jgomila> i know
| |
| 09:54 | the local computer can have a prebuild environment ? to reduce bandwith required ?
| |
| 09:55 | I have a computer in a housing in or private network, that all the offices can reach
| |
| 09:55 | <vagrantc> i think alkisg implemented some support for syncing images from the server for semi-disconnected operation
| |
| 09:55 | but that wouldn't work well for dynamic data
| |
| 09:57 | basically, the LTSP image is a read-only image, that then mounts a writeable layer in tmpfs which disappears at reboot
| |
| 09:57 | you can also mount some network filesystems to be able to write and keep files between reboots
| |
| 09:57 | by default, it's done on the server by mounting the user's homedir over sshfs from the server
| |
| 09:58 | the local traffic is pretty minimal, if using fat clients
| |
| 09:59 | thin clients are an option, but with hardware in this day and age, tends to be suboptimal
| |
| 10:03 | <jgomila> I will continue investigating
| |
| 10:04 | thanks for your help
| |
| 10:04 | <vagrantc> good luck

| 22:42 | <lazlo> Hello world!
| |
| 22:46 | I want to ask for a bit of help. I have been trying to set up an LTSP vm on my server and then launch a thin client from vbox in windows.
| |
| 22:48 | I can get a PXE boot set up and get a login prompt, however it is not for the user I created in the chroot, it's for the server it's self. In short, LTSP doesn't seem to be using the chroot.
| |
| 22:49 | I am running the LTSP install from Ubuntu server 16.04 with lubuntu-core installed via tasksel.
