Helo, i set up a Edubuntu 8.10 LtspServer version 5.1.29 and I have 10 Clients DellGX110 with 3c905c Card (Earlier running on Windows). Nothig works. When i boot the Clients most only one will boot up to the Login Screen. The Other get a Error "nbd0: Attempted send on closed socket" then i have to reboot hard. The first switched on client mostly boots to the login screen.   I asked in the ltsp irc channel they told me i have to flash t

<knipwim>
as help i could only find this link: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/310250
03:08
<rcmysoft>
yes, its a bug in version 5.1.25 i have the version 5.1.29 and the bug is should be solved
03:12
<alkisg>
rcmysoft: mostly boots to the login screen => you mean ldm (graphical login), or the text mode login (vt1)?
03:15
<rcmysoft>
i mean the ldm Graphical login
03:16
the next text mode login crashes on the other clients, only the first is going to ldm
03:19
will be in 30 min back

did you try Gadi's suggestion?
03:53
18:11 < Gadi> treyh: edit the screen script (or wrapper if you have one) and add -u '' on the same line as rdesktop
03:54
i'm pretty sure that i have done that already, but i'm going to have another go.

noone a idea? can it be a networkcard problem? autonegotiation half or fullduplex?
09:57
<Bushmills>
network card problem is very unlikely
09:58
<treyh>
rcmysoft: you still around?
10:05
<rcmysoft>
yes. On monday i will try something with the full and half duplex
10:05
but i am not very sure that the right thing to do
10:05yanu has quit IRC
10:06
<rcmysoft>
but it can be a connection problem
10:07
something like it works and works not. Its difficult because thats clients and i can#t debug anything

hey make sure you're using two network cards on the server, make sure that dhcp is running, and that tftp is running
10:31
<GGD>
hey trey...
10:32
treyh
10:32
or anyone in here i have a question
10:33
if you are attempting to do a VM using virtual box will that work? or does it actually have to be two phyiscal nics?
10:33
<treyh>
it will work
10:34
<GGD>
the virutal box
10:34
?
10:34
<treyh>
yes but you'll have to switch the ltsp box from nbd to nfs
10:34
if you use ubuntu
10:34
<GGD>
i tried to get it to boot to the ltsp portion of the CD installer and it wouldnt even give me that option
10:35
<treyh>
read the howto
10:35
<GGD>
i did
10:35
twice
10:35
<treyh>
had to hit F4 after you clcik inside the virualbox
10:35
<GGD>
did that
10:35
<treyh>
not sure then
10:35
<GGD>
the option didn't come up for me
10:35
it gave me everthing in the list EXECPT that
10:36
<treyh>
did you download the alternate cd installer?
10:36
<GGD>
i would very much like to set one up
10:36
i didn't know that they had one of those
10:36
<treyh>
go back and read the documention
10:36
there is an alternate cd
10:37
<rcmysoft>
it ist possible to switch ltsp 5.1.29 to nfs export in playce of nbd-server, i think the nbd thing is buggy
10:37
<GGD>
oh ok do you know where at in the documentation it is...
10:37
beacuse i thought it was all in the install CD
10:37
<treyh>
rcmysoft: yes
10:38
<rcmysoft>
is there a how to for it?
10:38
<GGD>
thats what i got from the documentation i read
10:38
<treyh>
https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
10:38
rcmysoft: yes not sure where, you'll have to search for it
10:38
rcmysoft: I don't think your problem is nbd though
10:38
brb at work
10:40
<rcmysoft>
the squashfs mount fails so i thought let it try with the nfs if the duplex stuff will not work
10:40hanthana has joined #ltsp
10:41
<treyh>
rcmysoft: try k12linux.org, try that version, it's the quickest easiest install version I've used
10:41
ubuntu is much better in the end though
10:42
<alkisg>
GGD, I've installed ubuntu with nbd in vbox many times with no problems
10:43
<treyh>
rcmysoft: I doubt either of those will fix it
10:43
GGD, same here
10:44
rcmysoft: do you have two nics and are you using dhcp off the ltsp server?
10:46
alkisg, he didn't download the alternate cd
10:46
<alkisg>
Yeah, the desktop cd also works fine
10:46
<treyh>
with the f4 option?
10:46
<alkisg>
No, apt-get install ltsp-server (or ltsp-server-standalone)
10:47
The f4 option (=install an ltsp server) is there only on the alternate cd
10:47
<treyh>
yea
10:47
he was trying to do the f4 option on the desktop cd lol
10:47
<alkisg>
Ah ok didn't see that, sorry! :)
10:49
<treyh>
alkisg, all good
10:50lucascoala_ has quit IRC
10:53
<rcmysoft>
i have two nics one nic is handling everything dhcp tftp nbd and nfs exports the other is connected to another lan
10:53
and it does not work
10:53
<treyh>
did you just do the regular install, and then try it out
10:53
or did you modify it in any way
10:53
<GGD>
hmmm i am dl'ing the alt cd now
10:53
and i am going o try that...
10:53
<treyh>
cool
10:54
<rcmysoft>
i made a regular install from the alternate and afterthat i installed edubuntu
10:54
<GGD>
did it install everything that you needed to do a ltsp for it?
10:54
<treyh>
GGD, yes because one client will boot
10:55
rcmysoft, and you're sure it got dhcp from the ltsp server and not the existing lan, and do those subnets conflict?
10:56
<rcmysoft>
i am sure because i put off the second nic to debug the error i get nbd0: Attempted on closed socket erro on the other clients
10:57
<treyh>
i believe it always says that
10:57
give me a bit i'll check to see
10:57
<rcmysoft>
oki
10:57
wish you much luck. perhaps you can try the duplex thing?
10:58
<treyh>
rcmysoft, let me give you advice
10:58
<rcmysoft>
oki
10:59
<treyh>
rcmysoft, you've already been told by more than one person it's not a duplex issue. I am tryign to help you but if you don't answer my questions and just want to believe that you've found the problem. then go ahead fix it.
10:59
rcmysoft, but don't come back here looking for help until you're willing to answer questions and try things you might not think it can be
10:59
<rcmysoft>
sorry
11:00
<treyh>
rcmysoft, dont' apologize
11:00
answer my questions
11:02
rcmysoft, and you're sure it got dhcp from the ltsp server and not the existing lan, and do those subnets conflict?
11:03
<rcmysoft>
yes i am sure. the dhcpd conf has next-server option, too.
11:04
<treyh>
what are the two subnets
11:05
<rcmysoft>
192.168.2.0/24 is the foreign one the with ltsp server is 192.168.1.0/24
11:06
<treyh>
what ip addresses does the ltsp have
11:06
what are the ip's of both nics
11:07
<rcmysoft>
192.168.1.6 the adress of the ip server 192.168.2.1 the other nic
11:07
sorry the first ist ltsp server
11:07
<treyh>
what version of ubuntu did you use
11:07
<rcmysoft>
Edubuntu 8.10
11:08
ubuntu 8.10 alternate first installed the edubunt desktop
11:08
then edubuntu desktop
11:08
<treyh>
gotcha
11:08
the default ip range on there is 192.168.0.x i believe
11:09
not 192.168.1
11:09
let me ask you this
11:09
is the ubuntu server and your existing network really both using 192.168.0.x
11:09japerry_cat has quit IRC
11:10
<rcmysoft>
no the servers one nic with the ltsp server uses 192.168.1.0 network
11:11
<treyh>
ok you don't make sense
11:12
the ltsp server
11:12
what are it's ip's
11:12
<rcmysoft>
192.168.1.6
11:12
<treyh>
so it only has one ip?
11:12
<rcmysoft>
no the other is 192.168.2.6
11:13
but the clients are on 192.168.1.# and dhcp listens on this eth0
11:13
dhcpd
11:14
<treyh>
thats different that what you said before
11:14
let me be more specific
11:14
on the ltsp server, what ip is on eth0
11:14
<rcmysoft>
okay
11:14
192.168.1.6
11:14
<treyh>
and eth1
11:14
<rcmysoft>
192.168.2.6
11:15
<treyh>
which eth runs dhcp
11:15
<rcmysoft>
eth0
11:15
<treyh>
k
11:15
on eth0, what is your dhcp range
11:15
<rcmysoft>
192.168.1.20 -200
11:15
<treyh>
ok ty
11:16
when your ltsp client pxe boots, what ip does it get
11:17
<rcmysoft>
different. its depends on the number of clients the one gets .23 the other.35 and so one but sometimes only one clients get dhcpoffer and pack the others not
11:18
<treyh>
full ip
11:18
just give me what one of them gets
11:18
wait
11:18
no two
11:18
give me two of what they get
11:18
and don't guess
11:19
boot one up and read it off the screen
11:19
<rcmysoft>
but when they get a dhcp lease only the first client boot until the graphical loginscreen
11:19
<treyh>
thats fine
11:19
just do one then
11:19
<rcmysoft>
.23
11:19
<treyh>
no
11:19
give me the full 192.168.....
11:19
and do it now
11:19
<rcmysoft>
192.162.1.23
11:20jammcq has joined #ltsp
11:20
<treyh>
ok now boot a 2nd one while the first one is at the login screen
11:21
and while it's booting, uyou'll see what ip at the very beginning it gets, what is it
11:21
<rcmysoft>
192.168.1.35
11:22
<treyh>
and you did that just now?
11:22
you did it too fast to actually test
11:23
<rcmysoft>
they are very fast. After the first was in the login screen i booted the second the boot takes 1.2 Minute
11:23
the second one crashed
11:24
<treyh>
boot the second one first
11:24
what ip does it get
11:24
<rcmysoft>
turn off the first?
11:24
<treyh>
turn off both
11:24
turn on 2nd first
11:24
<rcmysoft>
ok
11:25
192.168.1.35
11:25
<treyh>
and you're at the login screen?
11:26
<rcmysoft>
no wait a moment
11:27
<treyh>
once you get to the login screen
11:27
<rcmysoft>
now
11:27
<treyh>
in the bottom right
11:27
what ip do you have
11:27
<rcmysoft>
192.168.1.35
11:27
<treyh>
can you ping it from your ltsp server
11:28
<rcmysoft>
have no access to the server its in another closed room, can access at monday
11:28
<treyh>
you have the login to it?
11:29
well you probably don't have ssh access
11:29
<rcmysoft>
i will try
11:30
the screen is frozen an when i click on preferences for reboot nothig happens
11:30
<treyh>
on the client?
11:30
<rcmysoft>
yes
11:32
<treyh>
well you're out of luck til you have access to the server
11:32
but check your setup
11:32
something seems wrong
11:32
doesn't make sense that one client works and the rest don't after the first one is up
11:32
try to ping the clients from the ltsp server
11:33
and then try to ping them from the existin lan
11:34
<rcmysoft>
thats the problem ony one client boots to the end the others gets the error, it doesnt make sense to me too
11:34
but the thanks for your try.
11:34
<treyh>
let me look at one other thing
11:35
<rcmysoft>
okay
11:36
<treyh>
rcmysoft: i just confirmed the default scope for ubuntu 8.10 alternate cd install is 192.168.0.x
11:37
what else did you change to make it 192.168.1
11:38
<rcmysoft>
i activeted dhcpd to listen on eth0 in /etc/default/dhcpd.....
11:38
<treyh>
i seem to remember someone saying that the default static ip on eth0 and the dhcp range we not in the same subnet
11:38japerry has joined #ltsp
11:38
<rcmysoft>
sorry i did not understand
11:39
<treyh>
rcmysoft, did you change the ip of eth0, or did you change dhcpd.conf in any way
11:40
<rcmysoft>
i changed the ip in /etc/networkin/interfaces and i changed the dhcp.conf to the 192.168.1 net
11:40
d
11:40
<treyh>
SEE
11:40
exactly
11:40
what have i been asking you this whole time
11:41
<rcmysoft>
you asked me for the ip's of my nics
11:43
<treyh>
i asked you in the beginning if you did a regular install or modified it in any way
11:43
you said you did a regular install and then installed edubuntu
11:44
after i asked you for the ip's
11:44
you said you didn't chagne them!
11:44
is there a reason you want to run them on 192.168.1.x instead of 192.168.0.x
11:45
<rcmysoft>
no i can change this back
11:45
<treyh>
change them back
11:45
reboot the server
11:45
and problem fixed
11:45
i think gnome network manager is probably the cause
11:45
nto sure, i don't do the alternate installer route, i build it from hand
11:46
what would probably be best
11:46
is to use the new alternate installer
11:46
should be a 9.04 alternate installer cd
11:46
use that
11:46
if there is one
11:46
if not
11:46
use the 8.10
11:46
and just reinstall
11:48
<rcmysoft>
ok. thank you. Can i ask you something? Do you believe that the network manager is able to break the daemons?
11:49
<treyh>
all i will say
11:49
is that when i install ltsp on ubuntu from command line
11:49
not using the alternate cd
11:50
i remove the network manager
11:50
but thats just me
11:50
most people don't
11:50
<rcmysoft>
strange.
11:50
<treyh>
works better for me
11:50
but
11:50
i only use one nic
11:50
instead of two
11:50
and use a windows dhcp server
11:50
so i'm strange
11:51GGD has quit IRC
11:51
<rcmysoft>
when i use another dhcp server all the clients get their dhcp lease. Not only one and only sometimes. This is very suspect.
11:52
<treyh>
rcmysoft, goodluck with your install, let us know monday how it goes
11:52
<rcmysoft>
oki.

'fraid not treyh, it'll have to wait 'til monday. that said i am 99% certain i have already tried it.

my bash scripting is hopeless though, i'm sure someone who knew bash scripting would solve the issue in a moment.

helo, does someone know how to mount nfs exports on thin clients? Is it necessery to write to the /opt/ltsp/etc/fstab file the mount option?
15:11
<treyh>
rcmysoft, do a search on google, you'll find a howto
15:11
rcmysoft, but once again, thats not going to resolve your issues, like I said before
15:15
<rcmysoft>
hi. I think i made a mistake i wrote a mount option to the i386/etc/fstab file and did not run ltsp-image-update the second thing is i add a portmap option to hosts.allow for the network. I can cause errors

<treyh>
rcmysoft, we talked earlier, you jacked up your network settings. you need to reinstall from scratch and leave them alone, that will fix both problems
15:19
rcmysoft, you can change anything you want but you since you messed the network portion up the easiest fix will be to reinstall and try out the clients before you change anything
15:19
that way you can verify your default install works

Is there a good tutorial on how to create a fat-client server?
20:29
<vagrantc>
nope
20:35
<zlirp>
I was talking with pmautils the other day.
20:35
If I understood him correct, there is automation to get local apps running easily...
20:35
pmautils, you there? :)
20:41
<pmatulis>
zlirp: yes, how did you make out?
20:41
<zlirp>
Ah, I'm just getting started actually.
20:41
Building an image on my server.
20:41
But I'm assuming this is all for a thin client, not a thick one.
20:41
<pmatulis>
zlirp: ok, take your time
20:42
<zlirp>
Did you have a link or any information on what I need to do to get a fat server goign?
20:43
pmautils: I figure I'll start with a simple setup first though. Make sure my netboot is working.
20:43
(setting it up off of a dd-wrt router)
20:43
<pmatulis>
zlirp: the term "fat" is not well defined. all i'm saying is that it's pretty easy to have an application run locally (on the thin client)
20:44
zlirp: this is all documented on the Ubuntu LTSP wiki
20:44
<zlirp>
cool, I'll continue to scour that as I poke aroun then :)
20:44
<pmatulis>
zlirp: ok
