00:04
<vagrantc>
johnny: i think ROOT is the full path, CHROOT is the basically $(basename $ROOT)
00:04
<generic>
vagrant
00:04
i want to do USB enable on my thin client
00:04
any idea?
00:05
<vagrantc>
with most LTSP5 implementations, it should just work.
00:05
<generic>
well
00:05
what i should do in lts.conf
00:05
<vagrantc>
nothing
00:05
<generic>
it cant
00:05
?
00:05
<vagrantc>
generic: what linux distro and release?
00:06
<generic>
ubuntu server and kubuntu desktop
00:06
on thin clients
00:06
my machine is amd
00:06
<vagrantc>
ubuntu 8.04 ?
00:07
<generic>
ye
00:07
yes
00:08
<vagrantc>
generic: user needs to be in the fuse group on the server?
00:09
<generic>
yes it is
00:10
<vagrantc>
generic: is there anything in /media/USERNAME/DEVICENAME ?
00:11
<generic>
what u mean>
00:11
do i need ltspfsd?
00:13
any thing in /media/USERNAME/DEVICENAME means?
00:14
<vagrantc>
generic: when you log into the server, does something appear in /media/USERNAME/DEVICENAME, where USERNAME is the name of the user you logged in as, and DEVICENAME is the name of the device.
00:16
<generic>
wait
00:16
<vagrantc>
generic: ltspfs mounts things in /media/USERNAME
00:16
generic: it most likely won't show a desktop icon on KDE
00:19
<generic>
well
00:19
when i plug USB in server it shows me USB as /media/USB
00:19
and thats it
00:20
well its pops up
00:20
?
00:20
uSB things
00:21
<vagrantc>
ok, so if you log in from a thin client, check if there is /media/USERNAME/USB when you plug a USB stick into the thin-clients.
00:22
<generic>
ok wait
00:29
hey strange do we have tftp files in /var/lib/tftpboot dir in LTSP5
00:29
i dun think so
00:30
<vagrantc>
yes
00:31
/var/lib/tftpboot is where the kernel that gets loaded at boot is
00:38
<generic>
well
00:38
seriously i dont have it on another ltsp server
00:38
which is amd intel XEon
00:38
i dun have nay thing in /var/liv/tftpboot
00:39
<vagrantc>
well, if you have /tftpboot, it will use that instead
00:43
<generic>
but nothing it that also my tftp is off
00:43
i dun know how its working
00:43
<vagrantc>
must be magic
00:44Q-FUNK has joined #ltsp
00:47
<generic>
well
00:47
what ltsp-build-client does
00:47
creast a dir in /opt
00:48
right and also in /var/lib/tftpboot
00:48
and in /etc/ltsp/dhcp
00:48
right?
00:48
<vagrantc>
yes, and calls ltsp-update-sshkeys which copies keys to /var/lib/tftpboot
00:54
<generic>
ok
00:54
then this is issue right
00:54
<vagrantc>
if your thin client fails to boot, it might be part of the issue
00:54
<generic>
hmmm
00:54
but that booting
00:54
ok
00:54
<vagrantc>
generic: what is your issue?
00:54
<generic>
only USB is not wotking
00:54
USB
00:55
<vagrantc>
generic: ok, so log in as a user, open up an xterm, and type: mount | egrep /media/
00:55
<generic>
wher on server
00:56
<vagrantc>
log in from a thin client
00:56
which will log in on the server
00:56
this will be the last time i repeat this stuff.
00:57
<generic>
ok ok
00:57
please wait
00:57
i cant get gUI on thin client
00:57
<vagrantc>
you can't now?
00:58
or haven't ever?
00:59
<generic>
cant now
00:59
am getting ip
00:59
<vagrantc>
you're booting a client now?
01:01
<generic>
yes
01:01
i was working yesterday
01:02
hey do i need to do any thing for usb in lts.conf
01:03
<vagrantc>
again, nothing.
01:04
for the most part, lts.conf should be empty.
01:04
that's one of the big differences with ltsp5 from previous versions
01:11
<generic>
hmmm
01:11
ok
01:12
am going to my ltsp server its on remote location will call yo from there
01:12

hi hi
05:18
<johnny>
urens, this is not an active time for this channel
05:18
it is more active during the weekdays
05:18
it is almost completely dead on the weekends unless you get lucky
05:20
<urens>
well.. then i just got lucky ;)
05:20
are you familiar with ltsp?
05:20
*guess so*
05:22
I busy making a testingenvironment at work with Ubuntu 8.04 /ltsp
05:23
when i boot my client, he gets a DHCPoffer and continues booting untill the mounting bit
05:23
he stops and gives me a Busybox console
05:23
after that he won't do anything
05:23
<laga>
are there any error messages?
05:23
<urens>
Google tells me almost nothing, so i hope that this is not an exotic problem
05:24
let me see
05:24
one moment
05:25
mount: Mounting /rofs on /root/rofs failed: Invalid argument
05:25
(that is the first mount line)
05:25
the rest also fails but with: No such file or directory
05:26
<laga>
urens: does /opt/ltsp/images/i386.img exist on the server?
05:26
<ogra>
how did you install it
05:26
(no, i'm not actually here ... )
05:27
<urens>
with the standard installation from ubuntu(alternate) While booting you get an option via F4 to install a LTSP server
05:28
@laga: iĺl check if the img exists
05:28
yes it exists
05:28
<ogra>
if you did that install varant, the image should exists
05:29
do you run more than one dhcp server in that network (that wouldnt work)
05:29
<urens>
the ubuntu server is the only dhcp server in an isolated environment
05:29
<ogra>
grep nbd|/etc/inetd.conf
05:30
what does that return
05:30
err
05:30
grep nbd /etc/inetd.conf
05:30
(no pipe sign there)
05:30
<urens>
for your information.. everything is still standard. nothing has changed
05:31
<ogra>
(in the returnede output there should be at least one line with the image)
05:31
*returned
05:31
<urens>
yes
05:31
<ogra>
ok
05:31
<urens>
do you want to see it?
05:32
<ogra>
nah, i belive you :)
05:32
<urens>
;)
05:32
<ogra>
did yu create an lts.conf file ?
05:33
(not that you should, but some ancient unsupported settings could break it=
05:33
)
05:33
<urens>
nope, never made it
05:33
<ogra>
weird
05:33
<urens>
i did check the /etc/ltsp/dhcpd.conf for correct settings.
05:33
but everything looks fine and it boots.... so....
05:33
<ogra>
well, if you get to the busybox prompt dhcp is already out of the loop
05:33
<laga>
can you check /var/log/messages and /var7log/daemon.log for anything interesting?
05:34
can you check /var/log/messages and /var/log/daemon.log for anything interesting?
05:34
stupid typo :)
05:34
<ogra>
sloppy shift key :)
05:34
<laga>
i'
05:34
ve been meaning to replace this keyboard for a long time..
05:34
<urens>
;).. im checking right nog
05:35
nog = now
05:35
/var/log/messages has nothing interesting
05:35
i'll check deamon now
05:35
<ogra>
daemon.log sould have the nbd mount attempt
05:36
<urens>
only dhcpoffers and requests
05:36
nothing about mounting
05:37
sorry but i need to go to a customer... thank you for your time ogra. maybe i'll see you later this afternoon
05:37
thanks a lot!!!
05:38
<ogra>

05:38

hi ogra
07:36
wb
07:37
i have found some more details about the 'not booting' problem
07:44
I see that the DHCPserver in ubuntu offers different leases then i mentioned in /etc/ltsp/dhcpd.conf
07:44
<ogra>
why did you change the file ?
07:44
<urens>
after the client boots and asks for the second IP-lease he gets a time out while getting info from the server
07:45
my server should be in a 10.0.0.0 range later on
07:45
<ogra>
the file only apples to the thin client interface
07:45
(by default)
07:45
<urens>
jep.. it's on eth0
07:46
<ogra>
what your server uses for the outbound interface is totally independent of that
07:46
oh, you didnt say you did install with a single interface initially
07:46
<urens>
my server has 2 interfaces. eth0 and eth1
07:46
<ogra>
dont change anything but the network values in dhcpd.conf, then it will work
07:47
<urens>
but eth1 is nog plugged in
07:47
nog = not
07:47
<ogra>
well, by default the installer checks for an internet connection during install and automatically picks the second interface to configure everything out of the box
07:48
<urens>
so when i understand it correctly. the eth0 (wich was plugged in while installing) is the external card now. And the eth1 is for the thin clients now?
07:49
<ogra>
well, was
07:49
before you changed dhcpd.conf
07:49
<urens>
i allready put back the backup
07:49
he is rebooting now
07:49
<ogra>
it should have configured a 192.168.0 network on that interface
07:51
<urens>
okay, the server has rebooted and my PXE client is booting right now
07:52
looks like the same problem...
07:52
let me explain what i see here:
07:53
het has loaded vmlinuz and initrd.img really quickly. he reinitialises the networkcard. He gets a new DHCP lease in the 192.168.221.0 range.
07:54
gateway = 0.0.0.0.... rootserver: 192.168.221.254.... rootpath: <empty> ..... filename: <empty>
07:54
he gets stuck after "filename" and after a few minutes gets a time out
07:54
no network traffic
07:54
<ogra>
paste your dhcpd.conf to the pastebot
07:54
!pastebot
07:54
<ltspbot>
ogra: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
07:55
<ogra>
and the output of ifconfig -a
07:55
<urens>
from the client? or the server
07:55
<ogra>
??
07:55
there is no dhcpd.conf on the client :)
07:55
indeed both from the server
07:58asac has joined #ltsp
07:59
<ltsppbot>
"urens" pasted "dhcpd.conf" (22 lines) at http://pastebot.ltsp.org/526
07:59
<ogra>
looks good
07:59
<ltsppbot>
"urens" pasted "ifconfig -a" (30 lines) at http://pastebot.ltsp.org/527
08:00
<ogra>
hmm, looks all good
08:00
<urens>
the dhcpclient gets an offer for 192.168.221.x
08:01
<ogra>
did you restart the dhcp server after changing the config back ?
08:01
<urens>
with subnetmask 255.255.255.0
08:01
i gave the server a reboot
08:01
should do the same trick
08:01
<ogra>
yeah
08:01
the client network is definately plugged into eth1 ?
08:02
<urens>
ill make a screenshot from the client (runs in vmware) so you can see the output
08:02
<ogra>
seems very much like the interfaces are flipped and you get an ip from another dhcpd
08:02
<urens>
jups! because the client gets an offer for the 192.186.x.x range
08:02
iĺl swap them
08:02
<ogra>
well, the client should get a 192.186.0.x address
08:03
(not 221)
08:03
<urens>
yeah that's the strange thing
08:03
<ogra>
i wonder if vmware has a builtin dhcpd ...
08:03
i only use virtualbox here
08:03
<urens>
i checked the /etc/dhcp3/dhcpd.conf... and everything is checked out (#) there
08:03
<ogra>
that file isnt used as long as /etc/ltsp/dhcpd.conf exists
08:03
<urens>
could be... ill look if i can find something!
08:03
smart thinking! ;)
08:05
the 221.x range was indeed vmware. i stopped the dhcp service from vmware and reboot the client nog
08:05
<ogra>
good
08:05
<urens>
o wait. need to switch back the cable from server
08:06
okay. he gets a second offer
08:06
And there she goes!! haha
08:06
<ogra>
good
08:07
<urens>
great! in a few seconds it booted
08:07
all because of that 'hidden
08:07
<ogra>
check if you can log in
08:07
<urens>
' dhcp server
08:07
<ogra>
might be that through all the back and forth of the ips the ssh keys dont match anymore
08:08
<urens>
it logged in straight away
08:08
<ogra>
good :)
08:08
enjoy then :)
08:09
<urens>
thank you a lot for thinking with me!
08:09
<ogra>
welcome :)
08:09
<urens>
have a great day, or night, depends where on the globe you are
08:09
;)
08:09
<ogra>
day still :)
08:09
<urens>
maybe see you later!

no matter what i do.. i can't get my chroot to read lts.conf from /var/lib/tftpboot :(
13:40
<Q-FUNK>
/var/lib/tftpboot/i386/lts.conf ... IIRC
13:40
<johnny>
i know
13:41
well its /var/lib/tftpboot/ltsp/i386/lts.conf
13:41
either way.. damn thing doesnt' read :)

<johnny>
i even switched away from dnsmasq's tftp for testing
13:53
<laga>
dnsmasq can provide tftp?
13:54
<Q-FUNK>
?!
13:55
<johnny>
yes
13:55
since 2.36
13:55
<laga>
nice.
13:55
<johnny>
i was using it at my ltsp install for 6 months now
13:57
<Q-FUNK>
laternatives should get updated in ltsp-server dependencies, then
13:57
<johnny>
it may be so in debian already
13:57
<Q-FUNK>
seeing how dnsmask can now replace 3 services, it'a a resource-saver
13:58
<johnny>
since i saw vagrantc updating it to include a new conf file
13:58
<Q-FUNK>
ah
13:58
<johnny>
in ltsp-trunk that is
13:59
it'd be nice to clean up ltsp-trunk sometime..
13:59
too much stuff all around
14:00
i'm still having another problem
14:00
cant' get one machine to boot off pxe at all
14:00
just get error missing mode
14:00
from tftp
14:00
either with tftpd-hpa or dnsmasq tftp
14:00
Q-FUNK, i am going to move dnsmasq over to anotehr machine soon, so i'll be using a seperate tftp service from now on
14:01
but for folks that don't.. tftp is great
14:01
<Q-FUNK>
johnny: one of the buggy PXE implementations which is picky on boot images?
14:01
<johnny>
i guess..
14:01
it just says "missing mode" :)
14:01
its' a machine from gateway
14:01
a p4
14:01
<Q-FUNK>
IIRC that requires using the ISC dhcpd
14:01
<johnny>
:(
14:01
dont make me do that :)
14:02
dnsmasq has had options added to make it nicer with certain buggy implementations
14:02
<Q-FUNK>
dnsmasq isn't smart enough to send TFTP file names that every PXE implementation likes.
14:02
<johnny>
seems like others could be added
14:02
like tftp-no-blocksize
14:02
<Q-FUNK>
iit does now? it never worked for me

i'm just saying it could be fixed and that the dnsmasq guy is amendable to such suggestions
14:02
<Q-FUNK>
IIRc the main issue with with the last character on the filename passed to the client
14:02
<johnny>
sounds fixable?
14:03
<Q-FUNK>
some clients have a problem with a null character last and others want a white space one
14:03
'for a long time, dnsmasq upstream siad he was aware of the issue, but didn't see the need to fix his RFC-complient implementation to accomodate buggy clients
14:04
<johnny>
i wish dnsmasq had irc
14:04
<Q-FUNK>
:D
14:04
<johnny>
a channel that is..
14:05
<Q-FUNK>
ah yes
14:05
<vagrantc>
i didn't update the dependencies for the ltsp packages in debian to allow for dnsmasq as an alternative to ltsp-server-standalone, but you can use it with ltsp-server
14:05
<Q-FUNK>
they have a mailing list
14:05
<johnny>
i know..
14:05
<Q-FUNK>
vagrantc: why not? it could make a server that is less resource hungry
14:05
<johnny>
but i hate mailing lists usually.. since most of the times i need a mailing list, it'd take a dialog across days to get an answer :)
14:06
<Q-FUNK>
we could still leave the old daemons as the prefered choice, but introduce dnsmaq as the 2nd choice
14:06
<vagrantc>
Q-FUNK: it's certainly crossed my mind, but i've been focusing on other changes.
