<hima_>
using epoptes with ltsp
17:28
is there a way to support sound
17:29
<vagrantc>
sound with ltsp, or sound with epoptes?
17:30
<alkisg>
hima_: if you're asking to listen to sound while assisting a student, the answer is "no, currently; but it's possible with pulseaudio if someone writes code for it"
17:30* alkisg waves, btw...

<alkisg>
vagrantc: so the nbd issue is solved?

hima__: if you didn't see our answers, check irclogs.ltsp.org
17:36
<hima__>
or sound with epoptes
17:36
yes sound with epoptes
17:37
now i use epoptes to teach my children in another room
17:38
and i wanted to speak to them , does epoptes support that?
17:39
<alkisg>
(07:30:00 μμ) alkisg: hima_: if you're asking to listen to sound while assisting a student, the answer is "no, currently; but it's possible with pulseaudio if someone writes code for it"

<hima__>
thanks alkisg
17:40
<alkisg>
np
17:50
<vagrantc>
alkisg: in sid, need to make sure it migrates to stretch
17:50
alkisg: there still is likely a failure to reboot problem
17:51
alkisg: and I should probably do more testing, to make sure it's fixed sufficiently

vagrantc: about shutdown, stgraber's hack was "poweroff -fp". My hack is "sleep 10 to allow shutdown services like nbd/ssh to properly disconnect; poweroff -fp"
18:26
stgraber's version was less error prone but it left processes and temp files on the server
18:26
<vagrantc>
alkisg: where's the hack injected?
18:27
<alkisg>
The real fix of course is to be able to reload the initramfs and properly shutdown the root file system from there
18:27
...which dracut can do, but initramfs-tools, not really
18:27
The ltsp service files are supposed to call nbd-disconnect
18:27
/usr/share/ltsp/nbd-disconnect
18:28
Btw, systemd has other issues that block shutdown as well, that are unrelated to ltsp

<vagrantc>
i've seen it take a long time to shutdown on various laptops occasionally
18:31
but never seen it block that i can recall
18:32
<alkisg>
If it finally shuts down, then it's not related to ltsp
18:32
Er, unless RM_SYSTEM_SERVICES deletes some services that confuse systemd
18:32
I've seen various normal installations that take a long time to shutdown
18:33
On such cases, one can enable persistent systemd journal to be able to examine what part blocks the shutdown process
18:34
The steps to enable persistent systemd journal are mentioned in comment 10 of https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1492546

<syrius>
oh mylanta...
19:03
just swapped the switch out on our ltsp network
19:03
it's flying now
19:03
old sys admin was using gigabit NIC's on all the computers but only a 100mbit switch
19:04
<||cw>
lol
19:04
nice one
19:04
<vagrantc>
heh
19:04
<||cw>
it's pretty amazing was giving it an order of magnitude more resources will do
19:04
<syrius>
it's.. insane
19:05
i'm hero of the office right now
19:05
haha
19:08
<alkisg>
The most stupid issue was when we had gigabit switch, gigabit server, and 100 mbps clients, and due to the flow contol issue the speed was at 100 mbps only
19:10
<syrius>
ouch
19:11
<alkisg>
It took us months to realize it, and years until we found methods to disable it even on unmanaged switches
19:11
<syrius>
lol
19:11
we've had this setup for years too :\
19:12
<alkisg>
!lan-benchmark
19:12
<ltsp>
lan-benchmark: If you have a mixed-speed network (gigabit server<=>switch connection, and 100 Mbits/sec clients<=>switch connections), then you might suffer from the !flow-control issue. To benchmark your LAN with epoptes, see http://www.epoptes.org/documentation/lan-benchmark
19:12
<alkisg>
...we developed this ^ to make sure all is running smoothly :)
19:12
<syrius>
yeah i'm watching the network w/ iftop on the server
19:12
and can see the clients pushing > 100mbit

syrius: next step: port bonding on the server
19:29
<syrius>
oooh
19:29
we only have 3 thin clients max at one time right now.. most times it's 1-2
19:29
so it's not an immediate need, but that's cool. better than having to switch everything to 10gbit

<||cw>
if your switch behaves right you'd only need the server on 10g
19:43
<syrius>
yeah we have a nice switch, but i keep forgetting the "good" one last couple days
19:43
at this moment it's a regular netgear gigabit switch.
19:43
so monday i'll remember to bring in the good one
