anyone who can help me with this problem. I have 3 computers connected in epoptes. 1 shows up and is connectable. and 2 is just showing up with a computer icon showing STD in it. and is not connectable. all 3 computers are on the same network

Sorry, Zorky. I am present, but don't have much experience with epoptes
09:46
<Zorky>
hmm
09:47
<Fenuks>
Zorky: Anything in logs? Both of them pingable?
09:47
<Zorky>
they are sitting on a separate net
09:48
<Fenuks>
NAT?
09:50
<Zorky>
no in a different country
09:50
<Fenuks>
And how do you connect to them?
09:51
<Zorky>
they are setup via a cloud server running epoptes server. and we connect to epoptes via x2go
09:52
<Mava>
1. draw picture, 2. consider routing, 3. consider returning traffic, 4. consider firewalling,
09:55
<Zorky>
theres 3 screens running. 1 is visible and able to connect to and see. the other 2 is not connecable. but only shows an pc icon with STD in the screen. an orange icon
10:00
here is a picture of the setup http://i.imgur.com/rcJGuZ1.jpg

im sitting from the public ip

gonna show another picture. now i see it's not complete :)

I have installed LTSP on Fedora 19 (with a lot of changes). It works now, but I can't get it to launch LDM. I need to run "/usr/sbin/ltsp-client-launch" but it don't work as kernel parm "init=/usr/sbin/ltsp-client-launch" and neither in "rc.local" (run with systemd). How should I run it ?

Ok, I am running into a pulseaudio issue which I cannot resolve, and cannot find very recent info on how to fix it in the modern distro.
12:10
Sound works on the client for a short time, and then the sound dies, with the only recourse to get it back being to reboot the machine.
12:10
Anyone able to help?

12:40
Anyways, are you familiar with pulseaudio and thin clients?
12:41

not really

I have tracked my issue down to something related to that
13:07bieb has joined IRC (bieb!~hbieber@173.226.16.130)

I have another issue as well, non pulse related. Is there a way to not show mounted drives on every users desktop, but only on the session where it is mounted? The ownership of the drive is being applied to the right user, but the actual device is showing on all desktops.

Hi, anyone here? I have a bit of a question
14:28
I have an ltsp server serving fat client images to machines
14:28
it's working fine and all, but I was wondering if I could, once the image is booted
14:29
syncronize the image to the local hard drive of the client, so, in the event of a server outage, the machine would still be able to boot localy
14:29
locally*
14:31
does it sound feasible ?
14:31mar77i has joined IRC (mar77i!~mar77i@213.221.253.66)
14:32
<mar77i>
hmm, how can I take control of an epoptes server from another machine?
14:33
<fzabala>
do you mean like with ssh or vnc or something like that?
14:34
<mar77i>
well, using the gui thingy
14:34
<fzabala>
is the other machine on the same network?
14:34
<mar77i>
sure
14:34
<fzabala>
sounds like you'd want to use VNC for that
14:35
<mar77i>
well, ssh -X should work... is that the only way?
14:35
<fzabala>
what distro is the server running ?
14:36
<mar77i>
edubuntu. we have those teacher laptopts that should be able to take control of the fully ltsp'd students
14:37
and I'm having trouble to make sense of things. Do you mean I can't run the epoptes "gui thingy" on another machine to control things like on the server?
14:38
<fzabala>
well, look
14:38
if you run a VNC server on the epoptes server, and connect through a client from other machine
14:39
it would be like using remote desktop on windows, for example
14:39
is that what you'd want to do?
14:41
<mar77i>
oh come on
14:41
didn't I just suggest ssh/X-forwarding?
14:42
<fzabala>
well, sure, that's another option, of course
14:43
depending on your settings could be better, but, why didn't you try that already if you're so sure it will work?
14:43
<mar77i>
I was looking for the privileged epoptes client to run the gui on another machine (not just an ltsp client).
14:45
<fzabala>
well, in that case I think you're probably not on the most appropriate channel
14:47
btw, I advice that if you know the terminology, you use it, otherwise you give the impression of not knowing what you're talking about, and will likely get replies that you might have already considered
14:48
<mar77i>
are you kidding me?

<fzabala>
this might just be my english skills not being up to the task, but when you said "gui thingy" I thought you were pretty lost
14:51
so I adviced to use VNC which is easier for beginners

15:06
I am also having an issue with drives showing up on the wrong desktop, and when a drive is plugged into the server, random users get prompted to mount it
15:09
<fzabala>
I'm sure you've already set al the flags to allow local devices and local sound, right?
15:14
<mar77i>
so. ssh -X indeed works.

hey, may i ask a question?
15:51
<||cw>
you just did...
15:54
<matthias_>
ok, i'm setting up an ltsp server. i already got one running as a thin client configuration with dnsmasq as dhcp proxy. worked everything fine. i want to setuup a network at my school. we have good workstations with i5 and 4gb ram. so i want to use a fat client system. as already said the thin clients config works fine but with fat clients config my clients that boot over network are showing the busybox. i'm running ubuntu 12.04 64-bit. and
15:55
and if i press f6 while the ubuntu loading screen it say socket connection failed..
15:56
<||cw>
and all you changed was thin to fat and rebuilt?
15:56
I'm not sure if anything else needs to be done.
15:58
<matthias_>
yes i only changed thin to fat just like here: https://help.ubuntu.com/community/UbuntuLTSP/FatClients
15:58
i created the ltsp-build-client.conf and the debconf.seeds and than ltsp-build-image again
15:59
*ltsp-build-client sry

er, fat clients
16:07
<matthias_>
ok thanks ||cw is ther sb else who could help me pls?
16:08
<||cw>
the one I know that could help isn't online right now
16:09
<matthias_>
||cw: you know when he comes online?
16:10
<||cw>
no, but I know he's in Greece, if that helps
16:11
<fzabala>
I'm working on fat clients, but I don't know what seems to be the problem with your config
16:11
can you pastebin your ltsp.conf or something to take a look at it?
16:12
I suggest doing a backup of the chroot, if possible, just in case you need to try something
16:14
<matthias_>
fzabala: which config do you mean? (backup done)
16:14
<fzabala>
/etc/ltsp/ltsp-build-client.conf
16:15
just the settings, if possible, ( the sample one is riddled with commented lines )
16:15
and, what command did you use to build the clients?
16:16
<matthias_>
i used ltsp-build-client
16:16
<ogra_>
did you chekc the lasa drivers on the device yet ?
16:17
*alsa
16:17
<matthias_>
here my config: http://pastebin.com/8i9e8x1W
16:17
<ogra_>
its very unlikley an issue with pulseaudio or the lts.conf or something else on such a high level
16:17
<matthias_>
ogra_: how can i check?
16:18
<ogra_>
open a local terminal on the cllient and check syslog and dmesg output
16:18
look for alsa stuff
16:18
<fzabala>
I see
16:18
<ogra_>
also check if alsamixer shows a device etc etc
16:18
basic alsa debugging :)
16:18
<fzabala>
just ot of curiosity, are you sure that your clients will run fine on amd64 arch ?
16:19
<matthias_>
ogra_: thats not my problem my client doesn't even boot up, it just shows the busybox after the ubuntu loading screen. and the driver worked well in the thin client modus.
16:19
<ogra_>
once you know it is fine, start blaming the next layer (pulse or its config) ... but 90% of audio issues are actually asla
16:19
oh, i thought you had a sound issue
16:19
<matthias_>
yes, because i've the same setup as i tested before with thin clients
16:19
<ogra_>
ignore me then :)
16:19
<fzabala>
I'd suggest you try changing the ARCH for i386
16:20
<matthias_>
no problem ogra_
16:20
<fzabala>
just for the sake of testing
16:20
<matthias_>
fzabala: you mean doing the samething for i386?
16:20
ok i will do
16:21
<fzabala>
same config, just change the arch before building
16:22
<bennabiy>
ogra_: I am the one with sound issues
16:22
<matthias_>
ok it's building for i386....
16:23
<ogra_>
bennabiy, oh, so i mixed you up ... well, then what i said above appiles :)
16:23
looks at the actual driver on the device
16:25
<bennabiy>
ogra_: I have checked on the local term when the audio cut out, and usually there is a queue of messages about not being able to push something into the queue
16:25
alsa failed to push data into queue
16:25
<digitalirony>
What would be a good hardware solution to use for the thin client client machines?
16:25
<ogra_>
bennabiy, that looks pretty much like a driver issue with the sound driver then
16:26
bennabiy, fix that and your sound will magically work
16:26
<bennabiy>
digitalirony: we have been using hp st5742 - for the most part it is a stable machine, although you need to do a fix for the video driver
16:26
ogra_: How should I go about that?
16:26
In the chroot or on the server?
16:26
<digitalirony>
bennabiy: what is the fix
16:26
is it well documented?
16:27
do you know of one that will work out of the box
16:28
<bennabiy>
digitalirony: We went with these because you can find them new for around 100, and used for around 30-50. I am sure there are places that sell them fairly well supported out the store, but I cannot think of any
16:28
The fix is adding a line to the pxelinux.cfg/default file
16:28
I posted on Ubuntuforums about it
16:29
ogra_: what is the best way to reinstall the sound drivers on the client image?
16:30
<ogra_>
what distro is that ?
16:30
<bennabiy>
I am also having issues with audacity crashing immediately on the client
16:30* ogra_ can only talk about ubuntu ... there alsa drivers come with the kernel package ...
16:30
<bennabiy>
I am running mint 15 for the server, but the client is built on 13.04
16:30
<other_other_joe>
heya folks
16:32
I was wondering if anyone could recommend a good way to get NFS to mount only the users home after login
16:32
<ogra_>
https://wiki.ubuntu.com/DebuggingSoundProblems ... not sure if that works on mint, also dont forget that mint suppresses (security) updates so you might not have the latest fixes installed
16:32
<other_other_joe>
instead of the entire /home on boot
16:33
<bennabiy>
ogra_: are you going to be around for a while? I need to go have lunch with my family. I will be back in 20 - 30 minutes
16:33
<other_other_joe>
I wrote a little ldm/rc.d script to do it and I thought it was working...I was mistaken however
16:33
<ogra_>
bennabiy, cant promise ...

other_other_joe: a users /home is required to complete the login process.
16:42
you'd have to do in via pam or something.

16:44
<other_other_joe>
right right
16:45
LDAP could do it I believe
16:45
if I don't set the NFS_HOME= var in my lts.conf it will try and mount it via sshfs though
16:46
it does just mount the single users home directory rather the the entire home as long as I use sshfs
16:46
I just need to figure out how to get it to use nfs instead
16:47
<||cw>
what's the problem with mounting all of /home via nfs? it's a very common linux thing to do
16:47
<other_other_joe>
I've got a lot of users
16:47
<||cw>
first, to mount each separate, you'd have have to define and export for each every user. I'd find that unmanageable
16:47
s/and/an
16:48
<other_other_joe>
I was concerned that the amount of home directories in there would add a lot of overhead
16:48
<||cw>
so? it's just a mount
16:48
how?
16:48
there's nothing that iterated them
16:48
<other_other_joe>
good question
16:48
<||cw>
its just a mount. does the number of files on a usb disk add overhead to mounting it?
16:48
<vmlintu>
||cw: at least with nfs4 you don't need to define every home directory separately
16:48
<other_other_joe>
I just thought I remembered reading that somewhere
16:49
<Hyperbyte>
||cw, you wouldn't need to create multiple exports. If you are allowed to mount an NFS export, you are allowed to mount all subdirs seperately too.
16:49

<Hyperbyte>
Z4PP3r, what's holding you back?
17:11
<Z4PP3r>
Hyperbyte, when i install ltsp-server-standalone, it installs unity.
17:11
should i install MATE on the server?
17:14
<other_other_joe>
when you build the chroot, if you don't speciify a desktop it'll use whatever is installed on the server
17:15
<Z4PP3r>
other_other_joe, hmm, but i installed Ubuntu Server- theres no desktop. so, how do i specify a desktop?
17:17
<other_other_joe>
I'm using fat clients and the flag was something like ltsp-build-chroot --fat-client-desktop xfce4
17:17
I'm sure there is something comparable for thin client chroots, I'd cat the ltsp-build-chroot script and see what you can find
17:18
<ogra_>
ltsp-server-standalone depends on "x-session-manager | x-window-manager"
17:18
any package providing either of these two will be fine
17:19
(any desktop session or window manager)
17:21
<bennabiy>
ogra_: still here?
17:21
<Z4PP3r>
so, install MATE on the server, then install ltsp-server-standalone, then ltsp-build-client?
17:22
<other_other_joe>
I think so
17:22
seems reasonable
17:23
you probably don't even need to re-install ltsp-server-standalone, just purge unity, install mate, and rebuild the chroot

installer a different kernel? I don't know
17:35
I'm totally guessing at the cause though
17:35
and I've no idea how to tell if that's the case, unless you're also getting a panic
17:36
<bennabiy>
When audacity is run, it totally crashes the audio, and if vlc is running for a time, the audio just dies and will not come back
17:37
<other_other_joe>
parsing your logs is going to be your best bet I think
17:38
sounds to me like pulse isn't routing because something is trying to grab the card

<Hyperbyte>
Z4PP3r, are you using thin or fat clients?
17:38
<matthias1>
bennabiy: yes
17:38
<bennabiy>
matthias1: Is it still an issue?
17:38
<Z4PP3r>
Hyperbyte, thin
17:39
<Hyperbyte>
Z4PP3r, then you don't need to mess with anything client related. LTSP uses the desktops that the server provides.
17:39
<matthias1>
i think here is the problem bennabiy in.tftpd[2246]: tftp: client does not accept options
17:39
<Hyperbyte>
Z4PP3r, so just installing MATE on the server is enough. Also, a word of advice:
17:39
<matthias1>
bennabiy: yes still an issue
17:40
bennabiy: here's the section of my log file http://pastebin.com/9eD4cYpu
17:40
<bennabiy>
matthias1: I was going to say, when I have had that issue, it was because tftp was not starting properly. What I had to do was manually issue the start command for tftp and then rebuild the client
17:41
<Hyperbyte>
Z4PP3r, while it may make sense to install Ubuntu server, since, well, you're installing a server... realize that you are in fact installing a server which has to serve graphical user sessions. It's generally either to just install Ubuntu desktop. If you don't, you need to install a graphical desktop onto your Ubuntu Server installation.
17:41
<bennabiy>
I have to go for a little while, I will be back
17:41
<other_other_joe>
bennabiy, when you sound dies use fuser on your /dev/snd directory and find out whats PIDs are using your card
17:42
<Z4PP3r>
Hyperbyte, ok, i installed MATE, and its building the client now... ill let you know how it goes...
17:42
<other_other_joe>
maybe trying killing any that aren't pulse and/or restarting pulse
17:43freedomrun has left IRC (freedomrun!~freedomru@unaffiliated/freedomrun, Quit: So long and thanks for all the fish)
17:43
<Hyperbyte>
Z4PP3r, the desktop is not used on the client though if you're using thin clients. In fact, only X runs on the thin client, and LDM (the LTSP login manager)... rest is on the server. So you only run ltsp-build-client once, and then never touch again. All the changes you want on the client, you should do on the server
17:44
The advice from other_other_joe to rebuild client after installing MATE is wrong.
17:44
But since it's building now already, you'll have to let it finish.
17:45
<Z4PP3r>
Hyperbyte, ooh. yea, im running into errors. i think im just gonna reinstall ubuntu server, ive really messed it up :/
17:45
<Hyperbyte>
Z4PP3r, pick Ubuntu Desktop.
17:45
Ubuntu Server == Ubuntu Desktop without the graphical stuff.
17:46
However, for LTSP, you need the graphical stuff. Might as well just pick Ubuntu Desktop while you're at it, will save you from having to mess around too much.
17:46
<Z4PP3r>
Hyperbyte, no, unity will be too slow. maybe i should do this on linux mint.
17:46
<Hyperbyte>
Z4PP3r, you don't have to use Unity.
17:46
Just install MATE afterwards, and tell your clients to use that.
17:47
<Z4PP3r>
oh, so have both installed?
17:47
<Hyperbyte>
Three steps. 1. Install Ubuntu desktop. 2. Install MATE. 3. Configure clients to use MATE.
17:47
Done.
17:47
<Z4PP3r>
ok.
17:47
<Hyperbyte>
Well 2.5, install LTSP....
17:47
:)
17:47
Z4PP3r, doesn't hurt to have both. Unless you really need the disk space.
17:48
<Z4PP3r>
Hyperbyte, but why do i need ubuntu desktop if i will use mate?
17:50
<Hyperbyte>
Z4PP3r, because it installs more than just Unity. It installs lots of libraries that graphical desktops need, as well as lots of useful applications (office suit, etc)
17:50
It's your choice. But my experience with doing server installations and then adding desktop afterwards, is that there's always some libraries or packages missing that screw things up.
17:51
But sure, go ahead and try... if it doesn't work out you can just reinstall again. :)
17:51
<Z4PP3r>
ok then. some program would probably require it anyway... so how do i do step 3, make it use MATE by default?

20:10
I glanced over it
20:12
<fzabala>
any ideas on that?
20:13
I haven't tried anything with sound over ltsp, so, I'm not youor guy for that
20:13
<bennabiy>
fzabala: Just a thought, if you have the space, you can have a tar repository which is updated over ssh to the fat client after the session is initiated
20:14
<fzabala>
well, that was kind of my idea
20:14
in a nutshell, I have a image that I want the clients to boot
20:15
I also have a very similar image created as a clonezilla backup, in case that helps
20:15
my idea would be to dump the image on the HDD via clonezilla, and then set the boot menu to boot from the network first
20:16
then update that image when needed with the ltsp client booted
20:16
but, if I just rsync the files from the client to the host HDD
20:16
<matthias1>
bennabiy: i added nbdport=2000 and nothing changes
20:16

I guess I am not understanding if your goal is for your fat client to take over the role of your server, in case of failure, or just in case the server is unavailable for it to boot from, but still serve as the server in all other applications

20:20
<bennabiy>
matthias1: It is my own vocabulary. vncish = of or relating to VNC
20:20
<fzabala>
I think that's the best way to put it, lol
20:20
<bennabiy>
Here is a thought,
20:21
<matthias1>
yes vnc but i would need portforwarding?
20:21
<bennabiy>
Make your fat client also a tftp server to localhost, and put in your dhcp.conf as a secondary server to failover to localhost
20:21
<fzabala>
O_O
20:22
<matthias1>
bennabiy: rdp?
20:22
<fzabala>
oh, ok, no, that wouldn't work if the primary server failed
20:22
for a sec I thought you were some kind of LTSP mad-genius
20:23
<bennabiy>
matthias1: I have remmina, which can view vnc , rdp etc
20:23
mad, yes, genius, no
20:23
<matthias1>
ok wait a second i'll give you the adress of my vm
20:24
can i write a kind of personal message in irc?
20:24
<bennabiy>
matthias1: I almost wonder if you need to start from scratch, and follow a set order in setting up. I have found this works
20:25
<matthias1>
bennabiy: jasny.dd-dns.de:3389
20:28
<bennabiy>
fzabala: I think I see what you are saying now...
20:31
matthias1: do you have a dual nic setup?
20:32
<matthias1>
no, but it worked fine without the proxy dhcp in fatclient modus, but with dnsmasq there problems
20:32
you clould connect now to my server if you want

One thing that helps if you are doing rdp is to disable backgrounds etc.
20:35
<matthias1>
bennabiy: what i will take a smaller resolution
20:37
<bennabiy>
Matthias1: are you running 12.04 server or desktop?
20:37
<matthias1>
bennabiy: desktop
20:37
<bennabiy>
in a VM?
20:37
<fzabala>
I didn't think it would be so hard to pull off, tho'
20:37
<matthias1>
yes 8 cores 8gb ram
20:38
<bennabiy>
Is the VM your ltsp server? and you are connecting a vm client to it?
20:39
<matthias1>
my ltsp server is in a vm and i've got a "real" client and a Client in a vm -> 2 clients
20:39
bennabiy: you can reconnect
20:39
<bennabiy>
matthias1: connected
20:40
<matthias1>
bennabiy: ok
20:40
do you do sth? because i just see my unity dash on the left
20:41
<bennabiy>
fzabala: if you actually set up a boot partition on your fat client, then updated that based on the server image, and then issued a grub update after each update on the fat client, it might work
20:41
