<ZAJDAN>
hi...is somehow possible see what IP had clients ?
11:04
<alkisg>
!client-list
11:04
<ltsp>
client-list: to get a list of all nbd-clients (which sometimes is the same as ltsp clients), run: ss -n | sed -n 's/.*:10809 *\([0-9.]*\):.*/\1/p' | sort -Vu
11:04
<alkisg>
!epoptes
11:04
<ltsp>
epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
11:11
<ZAJDAN>
I use epoptes, but now the client ara offline
11:11
I want to wake up them via IP-MAC
11:11
<alkisg>
Eh, epoptes natively supports WOL
11:12
You just click on the WOL button in the toolbar
11:12
<ZAJDAN>
aha I will try
11:12
<alkisg>
When a client is offline, it doesn't have an IP, so epoptes is using the mac address there

ZAJDAN: read this: http://www.epoptes.org/documentation/groups

"To be able to save detected clients and boot them with Wake on LAN, if they support it. That cannot be done from the Detected computers group as obviously it doesn't display offline clients."

11:18
<ZAJDAN>
fortunately I have all the clients saved in group(epoptes), so I cann see them even they are off
11:19
<alkisg>
Cool, then you just need to click the WOL button
11:19
<ZAJDAN>
super! works nice
11:27
is possible set for thin clients hostname?
11:28
now when I look into DHCP server from where gets the clients IP, so I do not see their hostname
11:29
<alkisg>
HOSTNAME=blabla in lts.conf
11:30
<ZAJDAN>
thnx

<quinox>
how well supported is WOL? I've tried it in the past with mobos that were supported to support it, but I never got it working
14:15
<alkisg>
quinox: sometimes the bios settings for that are a bit obscure, but I always got it working when I tried
14:15
It even worked with a pci card and the cable that connects wol to the motherboard
14:53
<quinox>
good to know , thanks

<jeremies>
Can I Ctrl-C the command "ltsp-update-image --cleanup /" without breaking ltsp installation?
21:23
<vagrantc>
should be fine
21:23
it should build the image in a new filename, and then copies it into place when sucessful
21:25
<jeremies>
ok thank you
22:06adrianor1 is now known as adrianorg
22:08
<jeremies>
why ltsp plays video well with vlc but not with firefox?
22:12
<vagrantc>
the same video?
22:12
fat client or thin client?
22:16
<jeremies>
the same video
22:16
thin client
22:17
<vagrantc>
!videoo
22:17
<ltsp>
Error: "videoo" is not a valid command.
22:17
<vagrantc>
!video
22:17
<ltsp>
I do not know about 'video', but I do know about these similar topics: 'video-without-flash', 'video-test'
22:17
<vagrantc>
!video-without-flash
22:17
<ltsp>
video-without-flash: Fetch video source of flash based media and play the video directly with Firefox, without the use of the flash plug-in: https://addons.mozilla.org/en-US/firefox/addon/video-without-flash/
22:18
<vagrantc>
jeremies: tin clients don't generally support video well at all
22:18
er, thin
22:19
basically, the server downloads the compressed video, uncompresses it and renders it, and then sends the uncompressed stream to the client ...
22:19
which is a *huge* amount of data
22:19
!video-test
22:19
<ltsp>
video-test: You can test your network and graphics drivers with http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_640x360.m4v. It's 640x360@24, which means it needs 66Mbit, which means you should be able to view it without dropped frames in e.g. 12 clients simultaneously
22:20
<vagrantc>
hm.
22:20
really want to be doing fat clients, or at least localapps with videos
22:21
though it is interesting that you're finding vlc playing welll
22:22
are you playing the video from a file, or from a URL ? if from a URL, then vlc might be selecting a different protocol from whatever firefox is using
22:23
<jeremies>
sorry I have to leave
22:24
but i play video with firefox with url
