<Grembler>
an arp timeout would indicate that networking is broken as a very low level
08:04
is your network problematic?
08:04
<sanjay>
so what i have to do ....
08:05
i am new in ltsp..
08:08
<Grembler>
I would write to the mailing list with which clients you are using, and a full output of the error produced
08:08
does the client get any kind of DHCP lease at all?

<sanjay>
PXE-E11 ARP timeout

TFTP CANNOT OPEN CONNECTION
08:18
Existing broadcom PXE ROM
08:18
Selected boot device not available
08:18
exactly there error giving...
08:33
grmbler>???
08:52
<Grembler>
you need to test if TFTP is correctly installed and running
08:52
try a simple tftp get on the server first
08:52
if that works, try on another machine on the same network
08:53
if neither work, you'll have to figure out why

hi im using ltsp in nbd mode and wanted to implement a failover system if the master server goes down. i used ucarp for an failover and configured nbd-client to use the persisent flag but still i get squashfs errors. what can i do or are there other failover options?

JustSomeGuy: I haven't looked at the code in years, but the problem with nbd failover used to be a bug on the client side. The client would not disconnect properly. Perhaps have a look there...

16:22
anyone think it odd to have a 2gig bond be saturated but 50 or so NFS fat clients?
16:22
s/but/by
16:24
<alkisg>
Libreoffice needs 120 mb to load, multiply that fifty times ...
16:24
NBD + squashfs will be 5 times faster
16:25* vagrantc should continue to explore the NFS image option
16:25
<alkisg>
Yeah that'd be very fast too, e.g. 4+ times faster than plain nfs
16:25
<joe_sizlack>
gotta stick with nfs for HA sake
16:25
<alkisg>
Switch to NFS + squashfs then
16:26
I.e. a single i386.img served over NFS
16:26
<joe_sizlack>
ah
16:26
<alkisg>
That's only 10% slower than nbd+squashfs
16:26
<joe_sizlack>
I'll look into that
16:26
<vagrantc>
i *think* that made it into ltsp 5.5.0
16:26
but it was barely tested
16:27* alkisg tested that but I don't know if all code was upstream...
16:27
<alkisg>
joe_sizlack: and of course you might also be able to use...
16:27
!local-boot
16:27
<ltsp`>
local-boot: If you want LTSP fat clients on a low-speed network, you can put i386.img on e.g. C:\Boot\LTSP\i386.img and use this command line in pxelinux.cfg: APPEND ro initrd=ltsp/i386/initrd.img init=/sbin/init-ltsp root=/dev/sda1 rootflags=ro loop=/Boot/LTSP/i386.img; IPAPPEND 3
16:27
<joe_sizlack>
haha, yea
16:27
I was looking into that as well
16:27
a while back
16:28
<alkisg>
You can copy the image with 1 command if you're using epoptes
16:28
<joe_sizlack>
it presents some troubles for me
16:28
<alkisg>
ok
16:28
<joe_sizlack>
i.e. people might steal the cards
16:28
<alkisg>
No internal storage?
16:28
<joe_sizlack>
nah
16:28
just sd's
16:28
sd slots that is
16:29
guess I could glue in the cards or something...
16:29
I'm also still running ltsp 5.4
16:30
nfs+squash didn't make it in until 5.5?
16:30
<alkisg>
It shouldn't be hard to backport it
16:30
<||cw>
joe_sizlack: what speed nics in the fat clients?
16:30
<alkisg>
It just involves one or two scripts...
16:30
<vagrantc>
i upstreamed something
16:30
it was surprisingly simple
16:30
<joe_sizlack>
10/100's
16:31
<vagrantc>
mount internally?
16:31
<joe_sizlack>
not sure I follow?
16:31
<vagrantc>
it's just a single initramfs-tools hook, it hink
16:31
<joe_sizlack>
oh
16:31
<vagrantc>
probably can drop it in and should work on ltsp 5.4.x
16:33
<joe_sizlack>
due you or have you guys had to tune your nfs mount options at all in the past?
16:34
or have you just run with things straight from the package?

<alkisg>
(06:31:34 μμ) alkisg: You could also use more network cards, or more nfs/nbd servers...
16:35
<joe_sizlack>
yea, I've got a couple more NIC's on the way
16:36
<vagrantc>
i've never done much tuning, but i haven't done any HA stuff
16:36
<joe_sizlack>
just thought it might be odd
16:36
"vers=3,rsize=1048576,wsize=1048576,namlen=255" for instance
16:36
ltsp mounts root with these, standard
16:37
<alkisg>
It's just the initramfs-tools/klibc defaults...
16:37
<vagrantc>
that might matter even more for NFS image support
16:37
wsize is kind of silly for a read-only moun. heh.
16:37
i haven't touched nfs options for probably 10 years
16:37
<alkisg>
initramfs-tools also doesn't support nfs4, while dracut does, afaik...
16:38
<vagrantc>
finally, something good about dracut
16:38
<joe_sizlack>
haha
16:38
yea, I wish I had v4 for the root
16:39
i did find that writing my browser's cache to a tmpfs mount sped things up and dropped traffic considerably, btw
16:40
if you guys wanna role something like that into the lts.conf for fat clients, it'd be rad :)
16:40
<alkisg>
File a bug report with the steps involved...
16:40
<joe_sizlack>
k
16:40

16:41
<alkisg>
Where does the browser cache usually go?
16:42
<joe_sizlack>
/home/$user/.cache
16:48
<vagrantc>
you're using NFS homedirs?
16:48
or sshfs?
16:48
<alkisg>
But not the whole .cache can be in a tmpfs, right? Because it'll slow down startup of some programs a lot...
16:48* vagrantc thinks it makes a lot of sense
16:48
<alkisg>
...because they'd recreate the .cache from scratch each time...
16:49
<vagrantc>
depends on how much theey rely on .cache
16:49
<alkisg>
I wouldn't want to have to check each program though
16:49
<vagrantc>
if you were using the same homedir for thin clients and fat clients, you might get interesting results
16:49
<alkisg>
To see which ones benefit from that and which ones don't
16:49
<vagrantc>
it's an interesting idea, for sure
16:50
oh, there's a package that does this!
16:50
i may even use it on my netbook

16:50
nfs, yea
16:50
<vagrantc>
unburden-home-dir
16:50
does exactly that
16:50
not sure how it would integrate with LTSP...
16:51
<joe_sizlack>
not the whole .cache, no
16:51
just for browsers
16:51
yea, profile-sync-daemon is a package that does it to cut down on read/writes
16:51
that's where I got the idea
16:52
<vagrantc>
my guess is the performance gains would be well worth it

<alkisg>
eatmydata?!
16:54
<joe_sizlack>
haha
16:54
<alkisg>
Assuming the ltsp server doesn't crash, and only thin/fat clients do crash, what would be the downside to using eatmydata, which disables fsyncs, on clients
16:54
?
16:56
<joe_sizlack>
interesting
16:56* alkisg also wonders if sshfs, without -o sshfs_sync, performs any better than nfs...
16:57
<vagrantc>
using eatmydata on fatclients ...
16:58
<joe_sizlack>
you think it would be dangerous?
16:58
<slackish>
alkisg: might be interesting to try it.. especially with -o ssh_command="ssh -c arcfour"
16:58
<joe_sizlack>
well, too dangerous
16:58
<alkisg>
!arcfour | echo slackish:
16:58
<ltsp`>
slackish: arcfour: http://en.wikipedia.org/wiki/RC4 is an SSH cipher which is more than 2 times faster than the default aes128-ctr. To enable it, set LDM_SSHOPTIONS="-o Ciphers=arcfour128".
16:58* alkisg is currently using that in 500 schools... :)
16:58* vagrantc tries to think of a scenario where eatmydata would loose data that *might* otherwise get saved
16:59
<slackish>
:)
16:59
<vagrantc>
didn't we discuss making arcfour the default at some point?
16:59
<alkisg>
I don't remember the outcome there...
16:59
vagrantc: do we need eatmydata though, or do sshfs and nfs have mount options that ignore sync requests?
17:01
<joe_sizlack>
nfs only has async afaik
17:02
that doesn't ignore sink but lets traffic continue to flow before it's certain it's been written
17:02
s/sink/sync :P
17:03
eatmydata or unburden-home-dir seem quite applicable
17:03
<vagrantc>
alkisg: i think they both have options that are similar if not identical
17:08
<joe_sizlack>
anyone think of anything catastrophic that might happen with eatmydata on a fat client crash?
17:08
I might try it...
17:09
<alkisg>
Do you also have async for /home in /etc/exports?
17:10
<joe_sizlack>
i do

17:13
<vagrantc>
for some dirs, unburden-home-dir copies a bunch of files, so it might be slow to startup
17:13
at login
17:14
oh, symlinks across filesystem boundaries with sshfs ... can cause interesting behavior
17:15
but maybe that will be fine
17:15
<joe_sizlack>
unburden uses Xsession hooks at login
17:15
that'll work fine with LDM, yea?
17:15
<vagrantc>
should
17:16
you'll need to enable on a per-user basis, or globally in /etc/default/unburden-home-dir
17:16
but it'd be easy to write an init-ltsp.d hook for that
17:16
globally, at least
17:17
<alkisg>
sshfs symlinks under /home in ltsp are not followed on the server so they should be fine...

17:18
<joe_sizlack>
my guys have some pretty large homes in some cases
17:19
if it copies the entire /home/$user to RAM that would take quite a while indeed
17:20
<alkisg>
joe_sizlack: have you verified that by putting the browser cache to ram, it indeed goes faster?
17:20
<vagrantc>
undurden only copies specific cache files
17:20
although it's a long list
17:20
<alkisg>
Or was that just because your network is saturated?
17:22
<joe_sizlack>
nah, I did that weeks ago
17:22Fenuks has joined IRC (Fenuks!~Fenuks@212.164.164.225)
17:22
<joe_sizlack>
it most certainly sped things up
17:22
<alkisg>
And how much RAM on the clients, open tabs on the browser etc?
17:23
Does it only help when clients have little ram and users have a lot of tabs open?
17:23
<joe_sizlack>
4gigs on the clients that are happy
17:23
2gigs on the clients that still complain a bit
17:24
they probably open a ton of tabs though
17:24
at least 10 or 15
17:26
I intend to have them all at 4gigs soon though
17:27
I don't mind throwing more NIC's at the bond on the server, I'm still gonna, this just seems to make sense overall
17:32
I'm gonna go upgrade 10 guys right now, actually.

17:32
<gbaman>
alkisg and vagrantc, the results are in :)
17:32
we did a larger test today with 15 pis
17:33
and I think a gigabit network...
17:33
15 pis, booted to login screen in about 1 min, 15 seconds
17:33
which isnt too bad
17:33
they were all started at exactly the same time for the test
17:34
so success, teacher involved is pleased with the results
17:34willianmazzardo has joined IRC (willianmazzardo!~textual@187.4.15.116)
17:35
<gbaman>
We are going to test libre office tomorrow all at same time
17:36* alkisg booted fat clients in 15 seconds with 10.04 + gigabit... but since then boot times have grown bigger
17:37
<gbaman>
thats impressive :)
17:37
pis do take about a min to boot normally anyway alksig
17:38
<alkisg>
They have sd cards, not real fast disks, right?
17:39
Anyways, with gigabit networking you should be fine, like locally booted pis
17:40
<gbaman>
yes
17:41
and we are talking about 15 pis booting at a time
17:41
at exactly the same time
17:42
<alkisg>
Booting takes about 50 MB, so it's not a big strain on the network
17:43
<ogra>
alkisg, fi boot times have grown bigger thats a bug !
17:44
<alkisg>
ogra: boot speed was a 10.04 goal, for 12.04 they didn't care as much :)
17:45
<ogra>
(my Ubuntu 14.04 XPS 13 boots in 7 sec ... from SSD though ...)
17:45
alkisg, i am one of "they" as stgraber is :)
17:45
<alkisg>
My 14.04 needs about a minute
17:45
<ogra>
just tell us and file bugs :)
17:45
<alkisg>
With the usual 1 tb sata disk
17:45
I'm trying, but I never see developers reply in launchpad :)
17:45
<ogra>
ah, yeah, SATA spin up time
17:46
<alkisg>
Only bug triagers which are trigger-happy to add tags, but don't actually help...
17:46* ogra looks at bugs every day ... though my focus is on crazy phone stuff nowadays

17:47* vagrantc waves
17:48
<gbaman>
interesting, 45 seconds from SD card, 80 seconds from network?
17:48
for pis
17:48
on gigabit network
17:48
only a single pi
17:48
the teachers timing might have been a little optimistic it seems
17:48
<ogra>
gbaman, USB NIC, no ?
17:48
<gbaman>
yes
17:48
<ogra>
right
17:48
that limits you to 24MB/s
17:48
<vagrantc>
gbaman: second boot any faster?
17:48
<gbaman>
the pis built in one is, yes
17:49
you want me to reboot it vagrantc?
17:49
<vagrantc>
yeah, usb network is ugly slow
17:49
gbaman: or boot a second one
17:49
<ogra>
and if it is a shared hub even less
17:49
<vagrantc>
gbaman: just to see
17:49
<gbaman>
that requires me to go find a pi... one sec
17:50
I was getting this tested remotely in a school quite a distance from me
17:50
via skype :)
17:50
<vagrantc>
gbaman: i.e. are two conseqitive boots faster is the basic question i'm getting at
17:50
gbaman: i mean, it's just curiosity, no need to go out of your way
17:51
<gbaman>
so you mean vagrantc, once the first one has finished booting, does a second one boot faster?
17:51
or at the same time?

just occurred to me, I cant actually test it right now, only 1 monitor and 1 ethernet cable
17:53
although I could easily swap the monitor cable, I have a funny feeling swapping ethernet would not go down well :D

Well prolly is. I use epoptes on a scholl lab. I have here 8 multiseat machines and 7 standalone machines, all run ubuntu 10.04 and the server runs ubuntu 13.10. For some reason the clients disconnects and i can only restart if im start the epoptes-client again on the machine

Epoptes doesn't support reconnections, because it mainly targets ltsp, where disconnections == system hangs anyway...

If it can't "see" the server for 17 seconds, it aborts its execution
