03:30
==> That means that you can set "KIOSK_OPTIONS" in lts.conf to point to a specific web page
03:30
E.g. KIOSK_OPTIONS='http://www.google.com'

I have a question for anyone witch can answer it :
06:25
do someone know how to setup a scanner plugged un an ltsp 5 client
06:25
?
06:26
<mgariepy>
have your tried the SCANNER=True in lts.conf ?
06:27
<franck>
yes I did
06:27
still not working
06:27
just info : the scanner works perfectly when plugged on the server
06:28
<mgariepy>
you need to have saned running on the client
06:28
installed on the thin client chroot.
06:28
<franck>
ok
06:30
<mgariepy>
it's part of sane-utils package
06:30
on ubuntu
06:31
<franck>
ok apt tells me it is already installed
06:33
<mgariepy>
in your session do you have SANE_NET_HOSTS variable ?
06:33
open a terminal and run: env | grep SANE
06:35
<franck>
not seems to be set
06:35
your command returns me nothing
06:35
<mgariepy>
which os version are you using ?
06:36
<franck>
debian "squeeze" 6.0
06:40
<mgariepy>
hmm, i'm out of idea.
06:41
the variable is supposed to be set in the user session
06:41
can you paste your lts.conf file on pastebin ?
06:43
<franck>
Work in progres ...
06:43
<mgariepy>
does saned running on the thin client ?
06:44
<franck>
I don't know
06:44Gremble has quit IRC
06:44
<mgariepy>
you can run: ltsp-localapps xterm
06:45
this will open up a shell on the thin client
06:45
<franck>
wait wait wait, I found a tutorial at the end of the web, I think I'll thy it it seems to be nice
06:45
<mgariepy>

Hi people. Just installed and configured my new ltsp server on debian. Almost everything is fine. LTSP is fine, clients are connecting, rdp is fine.. But the keyboards are strange. For example the num lock part... the "Insert", "home", "delete", "end", "page up", "page down", etc.. aren't working fine. If I press, for example, the End on a client, it will show me the Start Menu of windows. (Clietns are connecting over ltsp and executing rdp for a windows ser

Hello everyone.
09:38
Just had a question about using some of the advanced build options, specifically caching and using that cache for future client builds. I am not sure that I completely understand and know how to set this up. There also doesn't seem to be much documentation that I have found on this.
09:54
<Gadi>
jtwood: I believe if you pass ltsp-build-client the option "--mount-package-cache", it will bind-mount the server's apt archive cache into the chroot
09:54
that way, all of the packages that the chroot downloads the first time can be available on subsequent times
09:54
if you do not want to share the server and chroot package archives, you can specify a different server directory to use
09:55
with: --mount-package-dir <directory>

jtwood: thanks for the help the other day. My LTSP setup worked great with your help. Booting from Grub is really simple too.
10:18
<jtwood>
Gadi: okay...I've done that. It just seemed that it isn't actually pulling the packages from the cache. I'll play around and watch what its doing on the next build.
10:20
I am sure its something simple. It seems that the packages are being cached. One other question, is much of these documented other than the basics?
10:24Kicer86 has quit IRC

<bieb>
Gadi: quick question for you.. my boss and the network admin redesigned out network last night.. changed the way we had subnetting etc. I reset the IP on my ltsp server, and the clients get the boot screen. but authentication does not work. We have AD and I am using likewise-open. I have disconnected and reconnected to the domain, with no luck. Do I have to update the ltsp image for the ip changes??
10:27jhutchins_lt has joined #ltsp
10:29
<Gadi>
bieb: sudo ltsp-update-sshkeys && sudo ltsp-update-image
10:29
<bieb>
Gadi: so that is the thing I am missing huh?
10:30
<Gadi>
jtwood: ltsp-build-client "plugins" are distro-specific, which is why you can get options with: ltsp-build-client --extra-help and not in the man page
10:30
if there were docs, i would look toward the distro wiki
10:32
<jtwood>
I kind of figured that...no biggie...thanks for direction though

Gadi: you still around?
11:05
<Gadi>
corporeally
11:07
<bieb>
ok.. after doing ltsp-update-sshkeys && ltsp-update-image ( iwas already sudo) when I boot one of the clients it fails to load
11:07
<Gadi>
fails to load how?
11:07
<bieb>
Mount: mounting /dev/nbd0 on /rofs failed:invalid argument
11:07
<Gadi>
you mean it does not boot all the way?
11:07
ah
11:07
do you have more than one image?
11:07
<bieb>
right doesnt complete
11:08
should only be one image
11:08
<Gadi>
try: ltsp-update-image --force
11:08
<bieb>
the next failed mounting are /dev /sys /proc
11:08
<Gadi>
seems for some reason, your nbd port numbers got screwed up
11:08
(you are oon Ubuntu, correct?)
11:08
<bieb>
then tells me target filesystem doesnt have /sbin/init
11:09
yeah ubuntu
11:09
<Gadi>
ok
11:09
try: ltsp-update-image --force
11:09
<bieb>
ok
11:09
<Gadi>
that will force it to recalculate the port numbers
11:09
and hopefully set you straight
11:09
<bieb>
sounds good..
11:09
will let you know
11:17
Gadi: when I run the update image.. there is no force option.. if I run it regular at the end I get 2 "Info" notes....
11:18
first.. Port 2000 is already defined with /opt/ltsp/images/i386.img in inetd.conf
11:18
second.. taking no action

<Gadi>
bieb: you did "--force"?
11:30
two dashes?
11:30
maybe ur on an older version
11:30
well then, you will have to make some hand edits
11:30
check: /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
11:31
make sure nbdport=2000
11:31
on the kernel command line
11:42
<bieb>
yeah I did --force. I do have an older version... 9.04
11:42
options are: base, port, no-comp,exclude-dirs,tftpbootdir,arch, and help
11:44
<Gadi>
ah
11:46
<bieb>
so my next step is the /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default??
11:51
<Gadi>
yeah: the port that the image is exported on (listed in /etc/inetd.conf) should match the port that the thin client is told to use (/var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default <- or 2000 by default)
11:51
<bieb>
ok.. I will check there
11:54* cliebow cliebow waves to Gadi and puts on snowsuit 8~)
11:54cliebow has quit IRC
11:59
<bieb>
Gadi: ok the /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default has just one line in it.. where should I add the ndbport?
11:59
DEFAULT vmlinuz ro initrd=initrd.img quiet splash
12:04
<Gadi>
on that line
12:04
after squash
12:04
put nbdport=2000
12:07
<bieb>
ok

12:14
these file changes are on the server not in the chroot correct??
12:21
<Gadi>
correct
12:21
make sure the server is listening on port 2000 -> sudo netstat -anp|grep :2000
12:26
<bieb>
yep.. listening

<bieb>
Gadi: what should I check next??
12:35
<Gadi>
hmm...
12:35
anything change in your image since last time?
12:35
<bieb>
I know.. its driving me crazy.. hate when they break things on Friday
12:36
<Gadi>
anything in syslog?
12:36
does syslog report that it is exporting i386.img?
12:36
<bieb>
nope.. well except I chrooted in and created a small text file in /tmp, just to give it a change
12:37
havent checked syslog.. what should I be looking for?
12:37
<_UsUrPeR_>
Gadi: about the rdesktop nosound issue I was having yesterday. I am still trying to figure it out.
12:37spectra has quit IRC
12:37
<_UsUrPeR_>
lFor the record, sound works from rdp to windows. just not rdesktop in ubuntu.
12:39
<Gadi>
bieb: also make sure your dhcpd.conf file is correct and it is handing out the right IP
12:39
_UsUrPeR_: what have you tried?
12:40
<bieb>
ok
12:40
<_UsUrPeR_>
gadi: rdesktop, remote desktop viewer, tsclient. rdesktop is the hopeful since I can put it in the lts.conf easily.
12:41
<Gadi>
_UsUrPeR_: you are straying off course
12:41
:)
12:41
_UsUrPeR_: ok, first things first - can you get a shell on the client?
12:41
(or ssh in)
12:41
<_UsUrPeR_>
yes
12:41
<Gadi>
ok
12:42
can you run alsamixer?
12:42spectra has joined #ltsp
12:42
<_UsUrPeR_>
yep
12:42
<Gadi>
good levels, nothing muted?
12:42
<_UsUrPeR_>
gadi: that is correct.
12:43
<Gadi>
ok, is pulseaudio running?
12:43komunista has quit IRC
12:45
<_UsUrPeR_>
ps aux |grep pulse shows it's running yes
12:45
/usr/bin/pulseaudio
12:46
<Gadi>
and if you kill it and log into rdesktop, does sound work?
12:46
<_UsUrPeR_>
one moment. let me check that.
12:49
gadi: no. It does not work.
12:49
<Gadi>
you still have the: -r sound:local option?
12:50
<bieb>
Gadi: syslogs are 0 bytes.. think we had turned it off way back.. dhcpd is not adjusted.. we use MS server to handle DHCP (it does dhcp for rest of company) all that was changed in the DHCP server was the new IP of the ltsp server
12:50
<_UsUrPeR_>
gadi: that is correct, yes
12:51
<Gadi>
bieb: thats an important piece of info
12:51
:)
12:51
<bieb>
:)
12:51
<Gadi>
bieb: go back to your pxelinux.cfg/default
12:51
<bieb>
ok
12:52
<Gadi>
and instead of nbdport
12:52
use: nbdroot=<ip-of-server>:2000
12:52
<bieb>
ok
12:52
<Gadi>
_UsUrPeR_: ps -efw|grep rdesktop verifies that it is called with that option?
12:54
<_UsUrPeR_>
Gadi: correct. It's showing "rdesktop -r sound:local <server ip>"
12:54
<Gadi>
is this 10.10?
12:54
<_UsUrPeR_>
Gadi: 10.04
12:55
<Gadi>
doesnt make sense
12:55
can you transfer a wav file to the chroot and play it with "aplay <filename>"
12:55
<_UsUrPeR_>
heh. ok, that will take a second
12:56
<Gadi>
just grab something from /usr/share/sounds
12:56
or some such
12:57
<_UsUrPeR_>
just updating the image now
12:57
<Gadi>
you could have just scp''d it to the running image
12:57
:)
12:59
<_UsUrPeR_>
fffffffff
12:59
now all images will have this .wav dammit! :)
12:59
my official decree :)
13:00
<bieb>
Gadi: changed the default config to nbdroot.. ran ltsp-update-image.. still get the same 2 notes at the end about port use and nothing being done.. boot client.. and same issue
13:01
<_UsUrPeR_>
gadi: aplay does work
13:03
gadi: have you verified this works for you?
13:21jtwood222 has joined #ltsp

<jtwood222>
When using alternate authentication, say kerberos or ldap, is it as simple as configuring pam to use these authentication methods on the LTSP server and configuring ssh to use PAM?
13:22
Thus allowing the LTSP clients to login with kerberos or ldap?
13:26
<Gadi>
sorry, guys
13:26
was on a call
13:26
<_UsUrPeR_>
no problem :)
13:27
<jtwood222>
Gadi: no problem
13:27
<Gadi>
_UsUrPeR_: I certainly have run rdesktop with sound
13:27
<_UsUrPeR_>
jtwood222: I have gotten openLDAP and LTSP to work with each other
13:27
jtwood222: totally possible
13:27
<Gadi>
_UsUrPeR_: do you have an ubuntu laptop handy - so you can check from there
13:28
<_UsUrPeR_>
Gadi: sure. Let me give that a shot.
13:28
<Gadi>
jtwood222: yeah, thats exactly how it works
13:28
<_UsUrPeR_>
any different parameters for me to try?
13:28
<Gadi>
_UsUrPeR_: shouldnt need any
13:28jhutchins_lt has quit IRC

<_UsUrPeR_>
k
13:29
<Gadi>
bieb: you dont need to update the image when changing pxelinux.cfg/default
13:29
in fact, just doublecheck that updating the image didn't *change* your pxelinux.cfg/default
13:30
<jtwood222>
Yeah, I figured and hoped that was how it worked...since I already have my WinAD working for authentication with everything. I would also assume that Unix Schema Extension would supply the home directory for the ltsp user and I could use pam_mount to mount the filesystem for the home directory...
13:30
<Gadi>
jtwood222: are you using likewise?
13:30jhutchins_lt has joined #ltsp
13:30
<jtwood222>
no...using openldap
13:31
<Gadi>
ah, ok
13:31
good
13:31
<_UsUrPeR_>
Gadi: same problem with a 10.04 desktop environment. rdesktop -r sound:local <server ip>
13:31
<bieb>
Gadi: no change to default
13:31
<Gadi>
_UsUrPeR_: sounds like it is a server side config problem
13:31
:)
13:31
<_UsUrPeR_>
:PPP
13:32
ok, if it works with windows remote desktop, does that mean that it could still be a problem?
13:32
it = server
13:32
in Windows, remote sound works
13:32
<Gadi>
so you say
13:32
:)

lol

omg
13:33
<bieb>
Gadi: I am looking for the How-to on using a windows DHCP server..
13:33
<Gadi>
no wonder linux refuses to play it
13:33
<_UsUrPeR_>
hahaha
13:34
<bieb>
other than dhcp.. what else should I be checking to get the desktop to load?
13:34
<Gadi>
bieb: you can do this:
13:34
in pxelinux.cfg/default
13:34
add: break=bottom
13:34
that will drop you to an initramfs prompt
13:35
<bieb>
k
13:35
<Gadi>
just after it was supposed to mount the stuff that it didnt
13:35
at the prompt, type ifconfig
13:35
and see if it got an IP
13:35
maybe the interface didn't come up
13:36
which could be a dhcp setting issue
13:36
see, here's the deal
13:36
<bieb>
I can do that now right? because that is where it leaves the client during the boot
13:36
<Gadi>
PXE gets an IP address from the DHCP
13:36
ah, right
13:36
so yeah, at the initramfs prompt, poke around a bit
13:36
<bieb>
without adding break=bottom
13:36
<Gadi>
right
13:37
anyhow, in the initramfs,
13:37
<bieb>
ok.. so ifconfig... anything else? should I try to mount things manually?
13:37
<Gadi>
the client gets its IP for a second time
13:37
<bieb>
ahh
13:37
<Gadi>
and then tries to mount nbd
13:38
now, where does it know the nbd server?
13:38
well, usually it uses the dhcp server
13:38
alas, for you, that is bad
13:38
so, nbdroot=<ip>:2000
13:38
should tell it to use that IP
13:38
<bieb>
right
13:38
<Gadi>
which is the IP of your ltsp server
13:40
nbd-client $NBD_CLIENT_ROOT_SERVER $NBD_ROOT_PORT /dev/nbd0
13:41
make appropriate substitutions
13:41
<bieb>
everything worked yesterday prior to the network changes.. once the ltsp server had a new IP, that scope was added to the Win Dchp server.. the thing I missed was updating the sshkeys and image.. we would get to the login screen but it would fail authentication.. once I ran the ltsp-update-sshkeys && ltsp-update-image.. thats when it stopped loading..
13:41
<Gadi>
right
13:41
I'm with ya
13:43
<bieb>
I hate things getting broken on a friday
13:43
<jtwood222>
bieb: AMEN to that!
13:44
<Gadi>
worst thing to break on a friday is the beer glass
13:45
<bieb>
very true
13:45
<jtwood222>
Haha...LMAO
13:45
<bieb>
ok.. off to check ifconfig..
13:45
<Gadi>
bieb: we'll get it going
13:45
its only plumbing
13:45
:)
13:47
<jtwood222>
Gadi: So you asked if I was using likewise...I am guessing that one way or another makes it difficult?
13:47
This setup is entirely in testing right now, so if likewise would be better way to go for ldap auth through a winad...
13:49
<Gadi>
well, I just got my bottom burned a bit by likewise
13:49
so< i would have given you some cautionary advice
13:50
seems they don't test much on multiuser environments
13:50
and a bunch of folks trying it with LTSP (myself included) would find that it would crap out after a certain number of users log in
13:50
<jtwood222>
Oh really? That is almost useless then...ouch
13:50
<Gadi>
(daemon would hang, system grinds to a halt or doesnt let future logins)
13:51
but, they gave me a version that is supposed to fix that problem
13:51
<jtwood222>
I am glad I just went with the good ol' standy then
13:51
<Gadi>
have yet to try it out
13:51
and confirm
13:51
because Im still wiping the egg off my face
13:52
aside from that issue, likewise was going great
13:52
so, I won't turn away from it
13:52
<jtwood222>
No doubt...I am just dabbling in replacing a lot of out M$ stuff with somewhat more robust and configurable (and in my mind a lot more stable) software...I would rather purchase support from the developers or donate then pay M$ licensing and be stuck
13:53
The AD Server and the TS Server are the only two we will keep...because AD is HARD to get away from once you've used it and there is unfortunately some software that you need Windows to run
13:53
<Gadi>
well, for this particular issue we lie in a weird nexus of the universe
13:54
right
13:54
have you been using seamlessrdp?
13:54
thats another one on my $hitlist
13:54
<jtwood222>
No, haven't run into that...looking for it right now
13:55
<Gadi>
hehe
13:55
fun times
13:55
ahead
13:55
lol
13:58
<bieb>
Gadi: ifconfig works and shows the correct client ip
13:58
<Gadi>
bieb: excellent!
13:58
<bieb>
if we make any changes to the win dhcp server.. I dont have to update the image correct?
13:58
it is just directing the clients
13:58
<Gadi>
right
13:58
we prolly wont touch it
13:59
have you tried the nbd-client command?
13:59
(at the initramfs prompt)
13:59
<bieb>
no..
14:00
nbd-client $NBD_CLIENT_ROOT_SERVER $NBD_ROOT_PORT /dev/nbd0 correct?
14:00
<Gadi>
but substitute
14:00
with actual server ip and port
14:01
<bieb>
so... ndb-client 172.18.16.25:2000 /dev/nbd0??
14:01
<Gadi>
no colon
14:02
<bieb>
space?
14:02
<Gadi>
nbd-client 172.18.16.25 2000 /dev/nbd0
14:02
<bieb>
ipcool
14:02
lol
14:02
ok..let me try that
14:02
<jtwood222>
Gadi:Oh beautiful...so from the quick look, its like an windows applications server pseudoclient
14:03
<Gadi>
what is?
14:05
<jtwood222>
seamless rdp...
14:05
<bieb>
Gadi: it gives a bunch of errors.. how can I make it stop so I can see the first error.. |more at the end didnt work
14:06
<Gadi>
well, what kind of errors are they?
14:12mistik1 has quit IRC
14:12
<Gadi>
jtwood222: yeah, it is an extension of rdesktop -> but it is mostly a hack - especially now that W2K8 allows you to publish applications.
14:13
<jtwood222>
Gadi: Yeah, I see that...but I am interested in exactly how it works with the M$ licensing...
14:14
Gadi: Have you played around with it at all? I know we have a couple of applications that our users/management will not move away from...otherwise Windows would be pretty much gone...
14:14
<bieb>
Gadi: End Request: I/O error, dev ndb0, sector 0
14:14
ldm_validate_partition_table (): disk read failed
14:15
<Gadi>
bieb: try this on the server:
14:15
sudo pkill nbd
14:16
jtwood222: dont read too much into it - you are just bringing up single aapps off the WTS using RDP, seamless just helps drop the Linux window decorations
14:16
<bieb>
anything else with the pkill? or after it?
14:16
<Gadi>
you still need to do all of the plumbing
14:16
bieb: then reboot the client
14:16
<bieb>
ok
14:16
<jtwood222>
Gadi: I did wonder if pam_mount mounting the filesystem on for the homedirectories on the LTSP server would be an appropriate way to mount the homes for the ltsp clients...I guess I am not exactly positive on the way the auth/fs mounting on the clients work...
14:18
Gadi: Gotcha on seamless...it still sounds like a good thing to check into anyway...I'll have to play with it to really know
14:18
<Gadi>
jtwood222: yeah - I find seamless to be a bit quirky
14:18
also, I usually have to write a wrapper to rdesktop so users have "single sign on"
14:18
for those apps
14:19
its all a mess
14:19
and all a lot of feeling ur way in the dark
14:19
<jtwood222>
Gadi: I was worried about that part of it...I've had enough feeling my way in the dark with the voodoo AD/Linux Integration
14:19
<Gadi>
yeah
14:20
I think ur alternatives to dark feeling are all commercial
14:20
<jtwood222>
Yes...they definitely are...
14:20
<Gadi>
OSS is good at providing lots of pieces
14:20
not usually so good (or willing) to put them all together
14:21
<jtwood222>
The problem is, those commercial alternatives, some of them just brute force everything together from what I have seen and don't work well with anything outside their package
14:21kalib has quit IRC
14:21
<jtwood222>
Yeah, but once you understand how the pieces work, it gets easier to make them work together...PAM was a big stumbling block for me...I know that...
14:24
<bieb>
Gadi: same thing
14:24
<Gadi>
bieb: the server and clients are on the same subnet?
14:25komunista has joined #ltsp
14:25
<Gadi>
bieb: and the client can ping the ltsp server from the initramfs?
14:26
<bieb>
initramfs doesnt have ping
14:26
<Gadi>
crap
14:26
<bieb>
they are on same subnet
14:26
<Gadi>
ah, can the server ping it?
14:26
<bieb>
let me try that
14:26
<Gadi>
we know the problem is with nbd-client
14:27
the question is: why can't nbd-client connect to your nbd-server on port 2000
14:27
<vagrantc>
firewall?
14:27
<Gadi>
show me, firewall!
14:28
*audience applause*
14:29
<bieb>
Gadi: server --> client ping = GOOD
14:30
<Gadi>
bieb:
14:30
on the server, do:
14:30
sudo tail -f /var/log/syslog
14:30
then reboot the client
14:30
and watch the syslog screen
14:30
<bieb>
ok
14:30
<Gadi>
and see if nbd-server fires at all
14:31
if not, hit ctrl-c
14:31
check your /etc/inetd.conf
14:31
make sure port 2000 is set correctly there
14:31
and: sudo service openbsd-inetd restart
14:31
for good measure
14:31
<bieb>
what should it say for port 2000?
14:32
<Gadi>
2000 stream tcp nowait nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/i386.img
14:33
or some such
14:33
<bieb>
ok
14:36
<jtwood222>
Gadi: Thanks for the advice with seamless and ldap...much appreciated. I've got some playing around to do...hopefully I don't mangle anything too badly...haha
14:36
<Gadi>
keep in touch
14:36
we'll bump heads in the dark
14:36
:)
14:37
<jtwood222>
Absolutely...just curious what your involvement in LTSP is...you seem to be on the ball
14:37
<Gadi>
im one of the devs
14:37
for many many moons
14:37
:)
14:37
<jtwood222>
I figured at much....alkisg too?
14:37

yup

seriously
14:38
where the heck is he?
14:38
<jtwood222>
Nice...I'm just learning this stuff really...was out of the Unix/Linux world since around 2000 so a lot has seriously changed
14:39
<Gadi>
you missed the lively days of LTSP
14:39* Gadi thinks we've sobered up too much since 5.0
14:39
<Gadi>
:)
14:40
<jtwood222>
HAHA...its always lively in the beginning isn't it...
14:40
<Gadi>
well, the global economy hasnt helped
14:40
<jtwood222>
Honestly, my headaches would be a lot fewer without windows...the thing I always know in Linux is that it can be done...Windows...that isn't always true
14:40
<Gadi>
everybody winds up working at 100000%
14:41
<jtwood222>
No, economy is bad...I agree...I work for an oil and gas company, so I've been fortunate...
14:41
<Gadi>

unless you're cleaning the gulf
14:41

14:42

Gadi: you went to UofP?
14:44

14:49
<Gadi>
is that the IP of the client?
14:49
<bieb>
yep
14:49
<Gadi>
then, nbd is fine
14:49
I think your image file is bad
14:49
<bieb>
crapppppppppppppp
14:49
<Gadi>
dont panic
14:49
make sure you are not low on disk space or something
14:50
thn:
14:50
sudo mv /opt/ltsp/images/i386.img /tmp/i386.img.backup
14:50
sudo ltsp-update-image
14:50
and make it fresh
14:51
all those I/O errors you were getting
14:51
can't be good
14:51
it means it has trouble reading from the image
14:51
<bieb>
ok.. so it will be an empty image?
14:51
<Gadi>
no no
14:51
<bieb>
ok
14:52
<Gadi>
it creates the image FROM /opt/ltsp/i386
14:52
<bieb>
whewwww
14:52
gotcha
14:52
how soon are you heading out?
14:53
<Gadi>
5 min
14:53
<bieb>
damn
14:53
<Gadi>
well, lets go over what we know
14:53
always easier this way:
14:53
nbd-client is what is reporting the IO errors
14:53_UsUrPeR_ has quit IRC
14:54
<Gadi>
but, the client is working -> nbd-server sees it request the file
14:54
<bieb>
right
14:54
<Gadi>
and exports it
14:54
so, either there is something wrong with the file
14:54alkisg_android has joined #ltsp
14:54
<Gadi>
or there is something wrong with nbd reading the file
14:54
<bieb>
ok
14:54
<Gadi>
you are checking the first one
14:55
<bieb>
right
14:55
<Gadi>
by rcreating a brand new image file
14:55
but, of course, it may still fail
14:55
<bieb>
right
14:55
<Gadi>
because all the other times it was created, it failed
14:55
as for the second option,
14:56
was there any sort of change in block sizes or any other network change that happened when they changed the scope on you?
14:56
<bieb>
no
14:56
<Gadi>
yeah, didnt think so
14:56
also, you had a working image
14:56
before you updated the image
14:56
<bieb>
yep
14:57
<Gadi>
so, something in the image update gave you an image that nbd doesn't like
14:57
tell me, is this a server you can reboot safely>
14:57
?
14:58
because I wonder if there might not be something else that is gumming things
14:58
up
14:58
<bieb>
yeah.. and it has been rebooted a couple times today.. I went into likewise and disconnected from the domain.. then reconnected, 2 different times
14:59
<Gadi>
so, if the update image fails again
14:59
try rebooting the server
14:59
and then rebooting the client
14:59
<bieb>
ok
14:59
<Gadi>
crappy kind of solution
14:59
:)
14:59
<bieb>
I know
14:59
I will take whatever works
14:59
<Gadi>
I figured
14:59
:)
15:00
good luck, bieb
15:00
I gotta run
15:00
<bieb>
this would not have been so bad next weekend.. when I am not busy as hell on Saturday, cause I could have used all day Saturday and did a rebuild of the image...
15:00
thanks Gadi

Gadi, was helping me with this earlier... but he had to go... my boss and the network admin redesigned out network last night.. changed the way we had subnetting etc. I reset the IP on my ltsp server, and the clients get the boot screen. but authentication does not work. We have AD and I am using likewise-open. I have disconnected and reconnected to the domain, with no luck. Do I have to update the ltsp image for the ip changes??
15:31
<vagrantc>
yes, you'd have to update the ltsp image for the ip to get put into the new ssh key
15:31
well, the new ssh key/ip address pairing
15:31
<bieb>
hey vagrantc did that..
15:32
let me try to run down what gadi tried..
15:32
we did the ltsp-update-sshkeys && ltsp-update-image
15:32
when the clients boot they get to the initramfs screen
15:33
from there I did ifconfig.. the clients are getting the correct IP
15:33
I can ping the client from the server
15:34
I have tailed the syslog.. here is the pastebin... http://pastebin.com/tt2pLjmV
15:34
I don't know what the first line means.. or if it is good or bad
15:35
we moved the current image file to /temp/img.backup and redid the ltsp-update-image.. still only gets to initramfs
15:36
netstat'ed the server to make sure it was still listening on port 2000, it is
15:37
that is all I can think of at the moment
15:37
:)
15:40
vagrantc: anything else you can think of?
15:41_UsUrPeR_ has joined #ltsp

15:47
not sure what's going wrong
15:47
everything sounds good up to that point
15:47
<bieb>
yeah its weird
15:48
I get the ubuntu screen, with the progress line going back and forth.. then balck screen with cursor in the upper left.. then bleccchhhh .. initramfs screen
15:49
the first error on the initramfs screen is: mount: mounting /dev/nbd0 on /rofs failed: invailid argument
15:50
then /rofs failes to mount on /root/rofs with invalid arguement
15:54troels has joined #ltsp

<bieb>
vagrantc: is there a How to on rebuilding your image from scratch, but keeping the current home directories and permissions??
16:01
<vagrantc>
the home directories aren't in the image
16:02
bieb: simply removing or moving aside /opt/ltsp/i386 and running ltsp-build-client again should start from scratch.
16:03
i.e. sudo mv /opt/ltsp/i386/ /opt/ltsp/i386.broken ; sudo ltsp-build-client
16:03
<bieb>
vagrantc: I just want to make sure when I redo the image, we use codeweavers so the students get MS office 2007, I didnt know if there was anything else I would need to do with the Docs in their home dirs
16:03patrickmw has quit IRC
16:03
<vagrantc>
bieb: that's server-side, unless you're doing fatclients or localapps
16:03
<bieb>
I am doing local apps.. but only firefox
16:05
ok..well this might be a time to fix some issues....
16:05
since FF is local.. student have a problem opening .pdf files directly from the browser, they have to save to the desktop and then open
16:07
are fat clients a good option overall?
16:09
<vagrantc>
if your hardware supports it
16:10
you need more ram and CPU on the clients
16:17
<bieb>
gotcha
16:18
do I need to run Adobe Reader local to be able to open .pdfs directly from the browser?
16:20
<vagrantc>
the simple answer is yes
16:20
<bieb>
what is the not so simple one?
16:21
<vagrantc>
you could install it locally, and then firefox will use it locally, you could configure your local machine to use remote apps ... you have many choices.
16:22
if you just install it locally, i think then it will only run when firefox or another locally running program needs to use it
16:22
you probably don't need to configure it to be used as a localapp
16:23
<bieb>
well how do I tell FF running as a local app to use Adobe Reader as a remote app?
16:24
<vagrantc>
that's an adventure that i don't know off the top of my head :)
16:25
<bieb>
:)
16:25
is there a how to for it?
16:25
<vagrantc>
the intarwebs would know better than i
16:25
<bieb>
or is it too much of an adventure for the How-to writers?
16:26
<vagrantc>
it relies on a lot of recently developed and not heavily tested features
16:26
<bieb>
ohhhhh
16:27
well how about this... IS it best practice to run FF as a local app?
16:29
<vagrantc>
it's not a terrible idea ... takes some load off the server
16:29
<bieb>
how many clients do you have?
16:29
<vagrantc>
but localapps have some issues with integrating with other apps, as you've noticed
16:29
<bieb>
yeah they do
16:30
<vagrantc>
the network i work with has about 10-20 terminals ... though different use-cases use different application servers
16:30
<bieb>
I see
16:30
are you running FF local?
16:30
<vagrantc>
i.e. some log in to a guest server, some have real accounts and such
16:30
not yet
16:31
<bieb>
I have 13 terminals.. Diskless workstations
16:31
<vagrantc>
i'm working on switching to fatclients as much as i can
16:31
just don't have the powerful servers to really be able to do thin-clients
16:31
<bieb>
I have the 1520 thin clients
16:32
<vagrantc>
all of the machines in use are just recycled PCs

server is (2) dual xeon processors, 16gb ram
16:32
I see
16:32
<vagrantc>
everything from p-II 450MHz w/ 128MB of ram to 2Ghz machines with 512-1024MB
16:33
<bieb>
nice array
16:35
do you think there would be that big a difference in speed running FF from the server instead of local?
16:37
<vagrantc>
only one way to find out :)
16:38
<bieb>
ohhh.. volunteering me for guinea pig duty?
16:38
<vagrantc>
fairly easy to test

vagrantc: will I have to configure likewise again? or is that just server based? our students authenticate to AD
16:59
<vagrantc>
bieb: i have no idea what you have to configure in likewise or AD
16:59
bieb: my guess is no, since you authenticate against the server
16:59
and you're not deleting the server
17:02
<bieb>
ok cool
17:02
<vagrantc>
almost everything happens on the server.
17:02
the thin-client is just an extension of the server
17:03
<bieb>
ok.. thanks for the info and help
