<ZAJDAN>
Hi...now I have tried put into ltsp.conf 'HOSTNAME=name' and watch if the name will be passed to DHCP server, but not...has been not passed
11:13
<alkisg>
ZAJDAN: the hostname goes to the client, not to the dhcp server
11:13
If you want to configure the hostnames in dhcp, put them in the dhcp config file
11:14
<ZAJDAN>
and is somehow possible set for Thin client hostname which could be passed also to DHCPserver?
11:16
I understand, that the client in the moment when boot has not hostname(of course, system is not ready)
11:19
<alkisg>
Why would you want to PASS it to the dhcp server instead of SET it in the dhcp server config?
11:21
<ZAJDAN>
alkisg: yeas...also possible to set static record for MAC, now I have dynamic IP, each restart of DHCP server will pass new IP
11:22
and when is dynamic assignment an I cannot see hostname, I do not know who is for the new IP
11:23
<alkisg>
ZAJDAN: i don't understand
11:23
Which dhcp server are you using?
11:25
<ZAJDAN>
at The Monday DHCP server gives for client 192.168.6.10 ...during night is power outage(reboot DHCP server) and after the reboot the client will get 192.168.6.181(for example)...in dhcp leases list I see not hostname, so I cannot recognize who is now the 192.168.6.181
11:26
and yes...I know I can solve it via StaticAssignment ...this MAC will get anytime this IP
11:27
but via the hostname I easy recognize who is who
11:29
<alkisg>
ZAJDAN: I have to leave now, but write a paragraph with the problem to explain it
11:29
You haven't even said which dhcp server you're using
11:29
<ZAJDAN>
mikrotik
11:29
<alkisg>
You can assign ip and hostnames with the dhcp server
11:30
<ZAJDAN>
yes via the StaticAssignment
11:30
<alkisg>
Yes
11:30
Normally you can do it with dynamic too, I don't know about mikrotik
11:30
<ZAJDAN>
but comfortable could be also recognization via Hostname when is used Dynamic
11:31
<alkisg>
Yes, dhcp servers can do that too
11:31
<ZAJDAN>
but ThinClients doesn't pass hostname to DHCP server "from Default"
11:32
<alkisg>
The dhcp server can pass the hostname to the clients
11:32
You don't need the clients to pass the hostname
11:32
<ZAJDAN>
aha..with this I have not experience
11:33
<alkisg>
https://tools.ietf.org/html/rfc1533#section-3.14
11:33
3.14. Host Name Option This option specifies the name of the client.
11:33
<ZAJDAN>
Thnx!

Why playing a video is so slow in firefox and plays well in vlc?

<||cw>
jeremies: assuming thin clients, vlc is probably using an X accelerated drawing method and firefox isn't

16:30yanu has joined IRC (yanu!~yanu@178-116-60-189.access.telenet.be)
17:02
<alkisg>
jeremies: VLC is using xvideo, which uses 12 bits per pixel, and stretches on the client, saving lots and lots of bandwidth
17:02
Firefox is using 32 bits per pixel and stretches on the server
17:02
There are plugins for firefox that can use xvideo
17:02
!flash
17:02
<ltsp>
flash: Yes, flash sucks. An HD full screen 30 fps video needs 2.5 Gbps bandwidth (1920×1080×4×30)! Make sure you have LDM_DIRECTX=True in your lts.conf file, or if it's just youtube you're after, try some flash replacing plugin like http://linterna-magica.nongnu.org
17:02
<alkisg>
E.g. linterna-magica
17:03
(I don't know if that still works or not)

I haven't encountered flash video in a long time, but it's probably the same issue for html5 video
17:16
just not sure there's such a fix
17:21vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
17:33
<alkisg>
Yeah I don't know if any plugins that "beam" the video to another player still exist in the html5/firefox quantum era

18:05sutula_ is now known as sutula
18:09
<jeremies>
alkisg: do you know a remote server that plays the youtube videos properly? Like windows rdp?
18:10
<alkisg>
Windows rdp doesn't play youtube videos properly
18:10
Except if you're using remotefx
18:11
<jeremies>
But do you know one better than ltsp?
18:12
<alkisg>
No, there is none
18:12
LTSP is the best there is
18:14
You can use e.g. kodi to watch youtube videos over ltsp with xvideo, i.e. fast
18:14
Any player that supports youtube with xvideo
18:14
<jeremies>
Yes, or youtube-dl too
18:14
<alkisg>
Yes. But not generic applications that don't use xvideo, like browsers
18:14* vagrantc presumes alkisg is talking about with fat clients
18:15
<alkisg>
No, with thin clients
18:15
<vagrantc>
oh!
18:15
<alkisg>
With fat clients there's no difference
18:15
The video is decoded on the client
18:15
So no bandwidth problems there
18:15
jeremies: the problem happens on thin clients that don't have enough cpu to decode the video themselves
18:16
<vagrantc>
so firefox renders video differently than a video-specific application?

18:16
<alkisg>
Yes, video players use xvideo
18:16
Firefox uses generic drawing methods, cairo etc
18:16
<vagrantc>
right
18:16kjackal has joined IRC (kjackal!~quassel@80.107.182.198)
18:21
<jeremies>
And some parameters in LTSP apart from LDM_DIRECTX=True for optimizing the video speed?
18:25
alkisg: like compressing video before sending or something like that?
