<alkisg>
Wouldn't it be better if SSH_ASKPASS was used in ldm instead of expecting "Password:"?
00:05
<Ryan52>
probably :)
00:05
what would you use?
00:05
<alkisg>
ldm again!
00:05
I mean, the greeter would get the password and keep it,
00:06
<Ryan52>
err, what?
00:06
<alkisg>
and the ssh_askpass program would be ldm (maybe with a command line switch) that asks the greeter about the stored password
00:06
<Ryan52>
okay.
00:06
<alkisg>
So no gui involved in SSH_ASKPASS
00:06
<Ryan52>
well, no, it would tell the greeter to ask for it with the prompt that is giving in ARGV.
00:06
for password expiry and stuff.
00:07
wow, that makes a lot of sense :)
00:07
how did we never think of that?
00:07
<alkisg>
Heh
00:08
<Ryan52>
probably we could just have a fifo (or something stupid like that) that lets a new program called ldm-askpass (or something stupid like that) tell ldm to talk to the greeter.
00:10
<alkisg>
Yeah... So, I think it should go like this: greeter gets username + password, then runs ssh with SSH_ASKPASS set to ldm-askpass, then ldm-askpass is called and signals ldm to ask the greeter about the stored password
00:11
<Ryan52>
ya.
00:12
<alkisg>
(I'm trying to find a way to minimize the timeouts, they're a major problem if the students keep forgeting their passwords... :))
00:12
<warren>
isn't ssh_askpass only for ssh key auth?
00:12
<Ryan52>
ya.
00:12
warren: works for passwords too.
00:21
<alkisg>
About password timeout: the ssh connection could be initiated when the greeter has both username + password. So the password timeout would be a greeter-only concern. E.g. if I enter a username and just wait for a timeout, ssh doesn't have to be called.
00:22
<Ryan52>
password timeout?
00:23
<alkisg>
I think there is one, isn't there? :)
00:23
<Ryan52>
I don't think so :)
00:23
<alkisg>
If I enter a username and wait for 10 minutes without entering the password, what happens?
00:23
OK, let me try...
00:25
But is my understanding correct that ssh gets run before the user enters his password?
00:25
<Ryan52>
nope.
00:25* Ryan52 just checked the code
00:26
<alkisg>
OK, sorry! :)
00:29
<Ryan52>
alkisg, are you intending on implementing the SSH_ASKPASS thing? if not, I will be happy to (after discussing with other people, and playing with it a bit) :). that would be a major improvement to some of the hackish stuff that we're doing...
00:30
<alkisg>
Ryan52: please do!!! I don't have much experience when it comes to glibc and stuff, I'm new to Linux
00:30
<Ryan52>
o i c. ok.
00:30
<alkisg>
Hmm... I just tried this: I entered the username, waited for 2 minutes, entered the password and I got "No response from server, restarting..."
00:31
So I guess there is a timeout somewhere...
00:31
<Ryan52>
it's not always no response..
00:31
if you entered stuff wrong it also says that.
00:32
<alkisg>
I think if you enter wrong stuff then it keeps prompting for a password for 3 times
00:32
<Ryan52>
not anymore.
00:32
they changed that at the last hackfest.
00:32
<alkisg>
Ah, ok

<vagrantc_>
the current behavior with incorrect passwords is a little wonky ... i think it just says "no response from server" and then dies.
01:29
<warren>
yes
01:30
<vagrantc_>
i seem to recall since the hackfest re-write it behaving kinda ok with multiple password attempts
01:31
<Ryan52>
so, vagrantc_ and warren, what do you think about alkisg and my crazy SSH_ASKPASS idea? :)
01:32rcy has quit IRC
01:32
<Ryan52>
do you see any reason for me to not just go for it? afaik, everybody hates the expect method :)
01:33
<warren>
Ryan52: could you please post the entire idea to the list?
01:33* Ryan52 nods
01:34
<vagrantc_>
Ryan52: i think it already uses SSH_ASKPASS ...
01:34
<Ryan52>
0.o
01:34
<vagrantc_>
maybe that was the python ldm ...
01:34
<warren>
Was Ryan in kindergarten back then? =)
01:35
<Ryan52>
recursive grep shows no matches.
01:35
<vagrantc_>
yeah. nothing in the current code.
01:35
<Ryan52>
warren, probably :)
01:35
does anybody know what the ml's address is? :)
01:35
<vagrantc_>
i *think* SSH_ASKPASS is probably a good idea, though i'm curious why it was dropped. i *know* it was implemented at one point.
01:36* vagrantc_ heads to sleep
01:36
<Ryan52>
bye
01:37
ah. ltsp-developer@lists.sourceforge.net
01:39
okay, I should sleep too ... tomorrow is the first day back to school after winter break :(

ooh, Gentoo is getting close? :)
04:20
<warren>
that topic hasn't been updated in months
04:20
<mraudsepp>
anyway, folks with Geode hardware and latest graphics stack around here?
04:21
<warren>
mraudsepp: I have both, but will not have access until I fly home in 3 days.
04:21
it was working fine when I tested it
04:21
<Appiah>
;)
04:21
<mraudsepp>
wonder if others are seeing freezes on rotation with geode-2.11.0 driver
04:21
<warren>
mraudsepp: no
04:21
mraudsepp: what version of X.org server?
04:21
<mraudsepp>
1.5.x or so
04:21
<warren>
xorg-x11-server-Xorg-1.5.3-6 here
04:22
<mraudsepp>
I think it's 1.5.3 with lots of EXA backports
04:22
including the glyph cache, which speed things up up to 5 times with some drivers and hardware, but slows geode down considerably.
04:22
<warren>
I haven't seen any issues, I tested the Geode LX thincan and craptastic uh.... another Geode LX thin client
04:22
<Appiah>
I'm troubleshooting a problem with my thin clients not being able to PXE Boot , the DHCP log and wireshark just shows the clients DHCP Discover over and over again. This happends when I start about 15 clients at the same time
04:23
<warren>
Appiah: not a bandwidth issue?
04:23
<Appiah>
it it can take about 20 restarts for a new client to be able to boot
04:23
warren: I dont think so
04:23
Beacuse I just boot them up
04:23
dont log on or anything
04:23
<mraudsepp>
warren: right, ThinCan is my reference too, being an Artec employee. Other high priority item is the EXA Composite gradient rendering bug
04:24
<Appiah>
I can the 15 clients at login for a hour , and then try to fire up a 16th client but it just wont get an lease
04:24
no DHPACK
04:24
<mraudsepp>
I'll try to update my stack a bit more in the background and get some traces later if it still freezes
04:24
<warren>
I don't know anything about the driver
04:24
I only test it
04:25
<mraudsepp>
yeah, I guess I will be needing to dig into the code myself at some point
04:25
<nubae>
Appiah: have u got remote logging enabled?
04:26
that can eat up your bandwidth and stop the clients getting connections
04:26
<Appiah>
I have no idea nubae
04:27
how can I force it off?
04:27
<nubae>
u would have done this: https://help.ubuntu.com/community/UbuntuLTSP/TCSyslogToLTSPServer
04:28
make sure /etc/default/syslogd looks right
04:28
<mraudsepp>
warren: http://bugs.freedesktop.org/show_bug.cgi?id=15700 was the gradient bug I had in mind of course :)
04:29
<warren>
mraudsepp: " I guess I will be needing to dig into the code myself at some point" does not inspire confidence
04:29
<nubae>
lol
04:29
<warren>
mraudsepp: yes, I'm the one that submitted that bug
04:29
mraudsepp: largely thanks to your company's thincan
04:30
<Appiah>
remote logging is not on
04:30
<mraudsepp>
warren: yeah, aware you filed it :)
04:30
<nubae>
Appiah: dunno then... gigabit network?
04:31
<mraudsepp>
warren: the guessing was that if no-one else is doing any geode X work, I will be forced to jump into X.org development that I haven't done before, that's all. The guessing bit is that I have no idea if OLPC folks will care to or not and at what capacity
04:31
<warren>
mraudsepp: OLPC let go their only person who was even remotely working on geode
04:31
mraudsepp: AMD's geode team is gone
04:32
mraudsepp: geode upstream is effectively dead now
04:32
<Appiah>
nubae: yupp
04:32
well atleast the server is on gigabit
04:32
bit unsure about the client
04:32
<nubae>
and the switch?
04:33
<warren>
Appiah: it is fine with only one client?
04:33
<mraudsepp>
warren: exactly. Might have to become "upstream" for some bits as ThinCan is alive and needing various love for Geode
04:33
<nubae>
olpc no longer even pays anyone to work on sugar anymore
04:33
<Appiah>
this can happen to all clients
04:33
<warren>
nubae: what!?
04:33
<mraudsepp>
there's SugarLabs though?
04:33
<Appiah>
after it gets it IP, I can restart it and it will get an IP directly
04:33
<mraudsepp>
not sure if they pay anything..
04:33
<nubae>
yup... thats independent
04:33
<Appiah>
I dont think this is a BW issue ...
04:33
<mraudsepp>
OLPC dumps windows on stuff? ;d
04:33
<nubae>
the last sugar dev stopped being paid in november
04:33
<warren>
Appiah: the switch could suck
04:34
Appiah: it is almost always the switch's fault
04:34
<nubae>
well, that said, there are only really 200 laptops currently running windows, so its not really about that
04:34
<Appiah>
I got one switch here thats pretty close to the server switch
04:34
the other clients are bit further away but they all show the same problem
04:35
<nubae>
Appiah: I'd try and see if its a hardware problem first... try a different switch different cables...
04:35
<Appiah>
I wonder which switch I should check then? the one the server is connected to?
04:35
<warren>
Appiah: did it work on this switch before?
04:35
<Appiah>
it is working
04:35
this can happen to any of the 20 clients
04:36
did not have this problem when we were using older hardware , and 8.04 and less clients
04:36
about 15
04:37
what hardware did you have in mind nubae ?
04:37
<nubae>
older hardware, u mean older clients?
04:37
<Appiah>
server hardware
04:37
was on a poor P4 ;)
04:37
<nubae>
hmmm, well thats indeed odd, normally upgrading the server should definitly improve things
04:38
<Appiah>
well it's a fresh install on a new server
04:38
and it's the only DHCP server on the network
04:39
<nubae>
firewall?
04:40
<Appiah>
not on this network
04:40
it's only the ltspserver and the clients
04:40
maybe a cisco phone beacuse I saw some skinny packages on wireshark
04:41
I restarted dhcp3 now and now I got the problem again
04:42
just DHCPDISCOVER DHCPOFFER but no dhpack
04:42|Paradox| has quit IRC
04:42|Paradox| has joined #ltsp
04:44
<nubae>
check /var/lib/dhcp3, maybe there's something in there about the leases
04:45
<Appiah>
what about them?
04:45
<nubae>
well, not sure, but its another place to look
04:46
<Appiah>
funny now it boots again
04:46
this is so friggin anoying
04:46
<nubae>
your cables are properly grimmped
04:46
I've had problems like that with badly grimped cables
04:46
that and broken switches
04:47
<Appiah>
so we got about 20 bad cables
04:47
or a bad switch? :P
04:47
<nubae>
nah, but one bad cable can effect the others
04:47
<warren>
one bad switch can work for some things but not others
04:47
95% of the time it is the switches fault
04:47
<Appiah>
I tried some dhcp snooping on a client switch but I didnt get anything
04:49
wait a sec
04:49
this client got like 4 leases O_O
04:50
for the same IP
04:50|Paradox| has quit IRC
04:50
<Appiah>
could that have to do with anything?

warren: while we were on the geode topic, feel free to give me a list with stuff that needs hacking on for geode, so I can have a better technical overview of what's the status of stuff. Soon we need to make some decisions on what to work on at company level, and it helps having a good list of additional stuff (I have lost of coreboot and few Xorg stuff only in my list right now). That goes for anyone using geode :)
04:54
<warren>
mraudsepp: well, the only issue I've had personally was that EXA composite thing
04:55
mraudsepp: I haven't had issues with coreboot ever since we wrote the intelligent patch for mkelfimage
04:56
mraudsepp: IMHO, the EXA issue and making it run stable should be done quickly, and then your company should just move on. Geode is near dead now. Too slow and obsolete, with much better stuff becoming lower power and cheaper.
05:10
<Appiah>
I found 2 things that are suspicious about dhcpd3 (i'm really trying evertything here)
05:10
it writes multiple leases for the same client (tried a new clean lease file)
05:10
and the time seams to be wrong
05:11
it says the client got a lease 11:07 but its 12:07
05:11
system clock says 12:07 too

warren: the too slow part is something that could be improved in Xorg, tbh. But there's only so much you can do
05:21
<warren>
mraudsepp: running it side by side with Athlon + ATI thin clients in Japan, it was noticably uglier. lower bit depth and slower to update screen...
05:22
<mraudsepp>
warren: if it wouldn't software fallback to cause pixmap migration ping-pong, I bet it would be a lot better as far as screen updates go
05:22
warren: glyph drawing is a joke with modern Xorg, for instance
05:23
<warren>
mraudsepp: I don't know the details, I only prodded upstream geode into being a public project and submitted testing data
05:23
<mraudsepp>
due to no A8 pixmap support. Solution should be simple enough - make EXA glyph stuff use ARGB instead of A8 when driver requests. For any other A8 cases you could do hardware conversion from A8 to ARGB - still should be better than software fallback and the related migration costs
05:23
<warren>
mraudsepp: even if these are software limitations to squeeze out a little more life out of geode hardware, realistically the manpower to fix it and keep it working...
05:24
<mraudsepp>
yeah, there's so much you can do
05:25
though I'm thinking to do some from home. There's low hanging fruit around the geode X.org stuff to get into X.org development more for OSS development stuff. And doing the important stuff from company time, the rest home to get experience to hack on the high hanging fruit radeon/intel stuff for my own machines benefits
05:26
<warren>
ok, well I'm interested in testing patches
05:26
I can turnaround test data on two different LX hardware quickly (if I'm home)
05:26
<mraudsepp>
I'm into improving GNOME performance stuff for everything. For that I need a slow machine to test what is slow - ThinCan sounds perfect, but not if performance profiles are full of X.org level stuff
05:27
<warren>
what is your role at Artec?
05:29
<mraudsepp>

05:29
I've been ending up working on everything we have non-ARM, mostly everything ThinCan related.

I'm thinking , either the DHCPoffer dont reach the client (the server does send it and writes a lease) or the DHCPRequest dont reach the server

warren: for coreboot, there's just lots of stuff possible to do to get it viable for more scenarios, and all that in upstream code in coreboot-v3. After I fix a NAND setup problem there (hopefully this week), v3 will work better than our internal branch whose binaries you probably have, when not counting the lack of VGA BIOS there. So beyond that there's all the other stuff necessary for other use cases than X.org with LTSP - USB boot, free VGA BIOS
06:11
with cb-v3, BIOS interrupts (SeaBIOS integration), PXE, USB support (keyboard at boot time), setup menu and so on and on

<cyberorg>
happy new year to you too ogra :)
06:21
<Appiah>
So I've still got a problem with thin clints PXE booting , it apears it has nothing to do with the amount of clients on.
06:21
DHCPdiscover -> DHCPOffer then it stops there
06:21
from sniffing in wireshark and DHCP log
06:21
this happens "sometimes"
06:21
you can reboot the client once or 15 times and it will work again
06:22
worked fine in 8.04 , this came in 8.10
06:22
<nubae>
Appiah: have u tried changing switches?
06:22

Appiah, try with wireshark on the client side. Of course not on the client itself, but with a pc connected to the client switch.
06:46
<Appiah>
with my laptop connected to the switch now I can only see broadcasted stuff
06:46
DHCP offer and DHCP Ack
06:47
<alkisg>
So there is a DHCP ACK?
06:48
<Appiah>
for one that's working yes ;)
06:48
<alkisg>
OK, try another one! :)
06:48
And keep the log, to upload it to pastebot

and it's plain pxe? no floppy, etherboot, gpxe etc?
06:58

plain pxe

ogra, do you remember why SSH_ASKPASS, ldm-askpass etc were dropped from ldm? I thought it was a good idea... :-/
07:06
<ogra>
i think that was dropped by sbalneav while he did the new chat protocol
07:07
<alkisg>
...and Ryan52 was interested to re-implement it (we didn't know that it was used sometime in the past, vagrantc told us)
07:07pscheie has quit IRC
07:07
<ogra>
ldm chats directly to ssh now
07:07
that would break a lot i think, talk to sbalneav
07:07
<alkisg>
OK, thanks
07:07
<ogra>
Ryan52 was in portland at the hackfest wheer scottie made the change
07:08
<alkisg>
I just thought it would be cleaner and get rid of some big delays
07:09R4f4 has joined #ltsp
07:09
<Appiah>
well alkisg it says pretty much the same , I see no differnce in the packages that I get
07:09
<alkisg>
Appiah, the timings are important
07:09
<Appiah>
what?
07:10
<alkisg>
If the client broadcasts a new dhcp_request right after the dhcp_offer, then the client thinks it's not suitable. If it's much later, it doesn't receive the offer.
07:11
<Appiah>
ok
07:11
We are gonna try another switch
07:11
then I'll look more on the time
07:12
<alkisg>
Appiah, also, is there a boot filename in this offer packet?
07:12
<Appiah>
root path =
07:12
/opt/ltsp/i386
07:13
<alkisg>
No, not root path, boot filename
07:13
<Appiah>
ah
07:13
yes there is one
07:17
kind of sucks when the clients starts working again

alkisg: the boot filename is in the offer packet
09:39
it still does not boot
09:39
We tried a new switch (cisco 29xx) now none of the 20 clients boot
09:40
<alkisg>
OK, maybe you have to compare the packets when it doesn't boot and when it does boot. It's pretty weird. Did you try with a hub?

ogra, well, ldm would still run ssh ... then the SSH_ASKPASS program would come back and talk to ldm again.
10:18
so it's probably not like it was before. Though I dunno how it worked before..

Hi, I've installed Kubuntu 8.10 and LTSP. New users get GNOME, when they log in for the first time, but I would like to get them KDE by default. How can I change this?
10:58* vagrantc wonders how many professional artists really would be motivated by winning a thin client ...
10:59* CAN-o-SPAM is determined to find out
11:00
<vagrantc>
:)

CrypTom, you could install kde-desktop..
11:08
<CrypTom>
cliebow: you mean "kubuntu-desktop", that is already installed!
11:09
but I also installed ubuntu-desktop to provide a choice for my pupils
11:09
but I would like them to get KDE by default
11:12
<vagrantc>
CrypTom: sudo update-alternatives --config x-session-manager
11:12
CrypTom: or maybe x-desktop-environment
11:12
<CrypTom>
vagrantc: im chroot (/opt/ltsp/) oder normal?
11:12
<vagrantc>
CrypTom: on the server
11:14
<cliebow>
not in chroot...
11:19
<CrypTom>
vagrantc: thanks, it was x-session-manager!
11:20
<vagrantc>
CrypTom: good good :)
11:21
<CrypTom>
do I need a special setting in order to make USB-Sticks on the thin-clients work?
11:21
I dont see any reaction, when I plug in a stick
11:22
<vagrantc>
CrypTom: there should be mounts in /media/USERNAME
11:22
CrypTom: i don't think KDE registers them by default
11:23
CrypTom: there is a bit of a hackish script to add them to the user's Desktop dir...
11:23* vagrantc tries to remember how to enable it
11:23
<CrypTom>
vagrantc: /media would be fine, but they dont appear
11:24
<vagrantc>
CrypTom: user in the fuse group?
11:24* CrypTom will check
11:26
<CrypTom>
vagrantc: cool, it works, the user was not in the group...
11:26
vagrantc: thanks again!
11:27
<vagrantc>
CrypTom: look in /usr/share/doc/ltspfs/examples for a script to add the icons to the desktop
11:28
<ogra>
Ryan52, well, i thought there were issues with the error handling and password update if you use SSH_ASKPASS
11:28
<vagrantc>
ah, yes.
11:28
<ogra>
but only scott can really answer this, it was his change
11:29
<vagrantc>
SSH_ASKPASS doesn't handle the password expiry stuff at all
11:29
<ogra>
yeah
11:29
<vagrantc>
so you'd have to do screen scraping/passthrough anyways
11:29
<ogra>
which is what his change was supposed to avoid
11:30
wow, i just had to get a 2G Sd card (not SDHC) for some special HW that can only handle SD and only up to 2G ... these things are three times as expensive as the 4 or 8G ones nowadays
11:31
<vagrantc>
well, it basically does a tiny bit of screen scraping, and mostly passthrough
11:31
<CrypTom>
vagrantc: cool, the icon stuff works, but it show an ugly ? instead of a nice icon, can that be changed easily?
11:31
<vagrantc>
CrypTom: you'd have to edit the script
11:32
<johnny>
will kde ever do the right thing here?
11:32
or whos fault is it?
11:32
<vagrantc>
CrypTom: look at all the lines referencing icon
11:32cor3 has joined #ltsp
11:32
<cor3>
Nice work on the ubuntu integration
11:32
<vagrantc>
CrypTom: find a kde icon name that you prefer, and let us know what to change it to
11:33
<cor3>
its become my 1st choice in os for ltsp deployments
11:33
<CrypTom>
I see "if dev.startswith('usb'): icon = 'usbpendrive_mount'
11:34
so, do I have to install some icon-theme package to get usbpendrive_mount icon?
11:34
<vagrantc>
no idea
11:35
CrypTom: you either need to install the icons it's referencing, or change the references to match what's installed on your system
11:35* vagrantc is no KDE fan
11:36
<vagrantc>
johnny: i think it was designed on GNOME, and nobody has ever proposed a clean way to get it working on KDE. it may require some changes in KDE to get it to work right.
11:37
<cor3>
xfce all the way
11:37
<johnny>
sure.. but suprising that the kde people themselves haven't wanted to do it right
11:37
perhaps nobody has ever talked to them about it? or what?
11:38
<CrypTom>
vagrantc: It works with: icon='drive-removable-media-usb-pendrive'
11:38
<vagrantc>
XFCE has the same issue as KDE, last i looked.
11:39
CrypTom: what version of KDE do you have?
11:41
<CrypTom>
vagrantc: kubuntu 8.10 with kde 4.
11:42
<vagrantc>
i suspect KDE4 changed the icon names or something like that
11:42
as the script was written on kde3.x, i'm guessing
11:43
<CrypTom>
ok

In Ubuntu 8.04, what needs to be changed in order to get USB flash drives to appear on client desktops?
12:12
is that in the udev rules someplace?
12:12
<Gadi>
you just need the user to be in the fuse group
12:13
<_UsUrPeR_>
gadi: ok, thank you
12:15

12:15
<Gadi>
many - one has 5 letters the other has 3, ....
12:16
<_UsUrPeR_>
:)
12:16
<Gadi>
a USB hdd may not be considered "removable"
12:16
by udev
12:16
you should check
12:17
<_UsUrPeR_>
just made an 8.04 install. It appears that, though my user is in the fuse group, neither a flash drive or USB hdd is working properly.
12:17
<Gadi>
other than that.... if it has an external power supply, use it
12:17
<_UsUrPeR_>
ahh.
12:17
hmm~~~
12:18
is that in 60-persistent-storage.rules?
12:19
<Gadi>
udevinfo -qenv -n ${DEVICENAME}
12:19
on the thin client
12:19
where $DEVICENAME is something like sda

<openstep>
I need to find the soultion and accopmplish tomorrow
14:13
<Gadi>
you should be able to update the x-session-manager alternative to point to xfce
14:14
<openstep>
so this command will sync the clients x-session manager on /opt/... with the one on the server????

the client's default session is the default session on the server
14:15
<cliebow>
openstep, what Gadi says
14:15
<Gadi>
this merely sets the default session on the server
14:15
<cliebow>
Gadi Rocks!
14:15
<warren>
CAN-o-SPAM: did you keep my earlier recommendation? (url to how it looks like in fedora)
14:16
<Gadi>
cliebow: you're better than those confidence-building cassette tapes
14:16
:)
14:16
<CAN-o-SPAM>
yea, i tried to send, it said not-a-member
14:16
<openstep>
Gadi: is that means that when I sit down by the server and set the default session I have to run this command to set it on the cleint???
14:16
<CAN-o-SPAM>
guess i'll join up
14:17
<Gadi>
openstep: right - run this command on the server and it will change the server's system-wide default setting for X session
14:17
the client just goes by the server system default
14:17
<cliebow>
.your default session is what evr it is on the server
14:17
<Gadi>
unless it chooses something else
14:17
<cliebow>
openstep, what Gadi says
14:18
<Gadi>
openstep: if you are running ubuntu right now, go ahead and run the command from a terminal
14:18
it won't bite
14:18
<openstep>
because right bow when I set xfce4 on the server to be default...then log out and back in it stays default but not on the clients
14:18
<Gadi>
:)
14:18
<cliebow>
ANd i look even better than those Cowboy cheerleaders
14:19
<Gadi>
openstep: well, you prolly set it as default for a gdm session
14:19
not an ldm session
14:19
<openstep>
well, I am not at the server now
14:19
<Gadi>
ldm goes by the x-session-manager alternatives default setting
14:19
openstep: are you on an ubuntu laptop?
14:19
PC?
14:20
doesnt have to be the server
14:20
<openstep>
it is an IBM x226

nowww
14:20

pop open a terminal window

nope sorry
14:20

14:21
oh
14:21
<openstep>
I am not at the server now, but tomorrow
14:21
<Gadi>
ok
14:21
yeah, this command doesnt work on Windows ;)

14:22

openstep: go for it
14:23
<Ahmuck>
stgraber: k
14:23
<openstep>
so when I would like to set a default session (like xfce) I do so on the server's login manager. This does not take any effect on the clients until....
14:24
this command:
14:24
sudo update-alternatives --config x-session-manager
14:24pmatulis has quit IRC
14:24
<Gadi>
A+ for execution, A- for understanding the theory
14:24
lets bolster the theory:
14:24
<openstep>
then every time I would like something different to be default I should repeat
14:25
<Gadi>
the only login manager you care about is the client's login manager which is "ldm"
14:25
(LTSP Display Manager)
14:25
the server's (in your case, gdm) plays no role here
14:25
LDM will use whatever the server's system-wide default X session is
14:26
(which need not be the same that you chose for your user in gdm)
14:26
To change the system-wide X session default, you run that command you quoted
14:26
What you do when you login at the server through gdm is between you and your Maker
14:26
:)
14:27
oh, and: Pete and RePete were on a boat. Pete falls out. WHo is left?
14:27
<openstep>
without that command it is only applys to gdm on the server
14:27
<Gadi>
openstep: gdm is only affected by whatever you set when you logged in thru gdm
14:27
but that does not affect the clients in the least
14:27
only your local gdm login when sitting at the server
14:28
<openstep>
yes and here comes this command, which somehow reads gdm's default
14:28
<Gadi>
nope
14:28
<openstep>
and applys it to be system wide
14:28
<Gadi>
this command simply sets the system-wide X session default
14:28
it will ask you what to set it to
14:28
it wont read it from anywhere
14:28
<openstep>
oh, t
14:28
<Gadi>
and if you started with stock ubuntu, the default will be gnome
14:29
<openstep>
that part i did not understand
14:29
<Gadi>
ah, my bad
14:29* Gadi always misses a step
14:29
<Gadi>
or an openstep, as the case may be
14:29
now: Pete and RePete were on a boat. Pete falls out. WHo is left?
14:29
:)
14:30
<openstep>
then sorry for asking one more
14:30
<Gadi>
go for it
14:31
<openstep>
running that command will ask me to type in my preferred session, right?
14:32
<Gadi>
something like that - it should be interactive
14:32
<openstep>
so for example in the case of xfce4 I just type in "xfce4"
14:32
oh, many thanks
14:32
<Gadi>
if it isn't, come back here and vent
14:32
we'll vent with you

I've got a few Dell machines that will pxe boot, and appear to load initrd.img, go to the splash screen, but not present a prompt. When I disable splash and remove quiet, it appears to get to Starting LTSP client, but then scrolls by too fast to see where it's hanging.

Additionally, if I tail -f /var/log/syslog, I see multiple connections from the client in ldminfod

16:44
<alkisg>
Maybe you could try setting X_SERVER=vesa in lts.conf
16:45
!lts.conf
16:45
<ltspbot>
alkisg: "lts.conf" is http://wiki.ltsp.org/twiki/bin/view/Ltsp/LtsConf
16:45
<Mip5>
okay - I have other clients that working fine (different hardware)
16:46
Can i specify that only this class of clients use the vesa in lts.conf?
16:46
<alkisg>
Yes, either for each one based on hostname/ip/mac, or with a LIKE stanza
16:46
See the url above
16:46
<Mip5>
okay - I'll dig into that. Thanks a bunch
16:46
<alkisg>
np
16:49
<Mip5>
okay - well I see that I had already set that previously (though I did it for all clients).
16:51
<alkisg>
Then maybe you should disable it! google says you have intel graphics card, which are supposedly supported.
16:52
You could also try to get a shell in the client and run X -configure and read the logs
16:52
i.e. put SCREEN_02=shell in lts.conf
16:54
<Mip5>
Wow - that's cool
16:54ogra has quit IRC
16:55
<Mip5>
I'll try disabling vesa first, and then will try to add the SCREEN_02 line to the stanza for this machine. brb

<Mip5>
killer! I've got a root prompt
16:58
<alkisg>
Heh! So run an X -configure :0 and then check at /var/log/X.?.log
17:01
<Mip5>
okay - so the log was very short - didn't look like typical Xlog to me.
17:03
<alkisg>
There are two file there I think, look at the other one
17:03
Xorg.0.log and Xorg.7.log or something
17:03
<Mip5>
I then tested it with X -config //xorg.conf.new and got the gray screen with an X (that moved via the mouse)
17:04
<alkisg>
Ah, right...
17:04
<Mip5>
Sorry - I don't really know much about this stuff (as you can probably tell!)
17:04
<alkisg>
So one way to solve this would be to ssh this xorg.conf.new to the server and use it with X_CONF=xxx in lts.conf
17:05
(but you'll also have to copy it into the chroot and run ltsp-update-image)
17:05
<Mip5>
I'm not sure I follow - are you saying to copy this xorg.conf.new to the stanza in lts.conf that defines the params for this machine?
17:05
<alkisg>
Yes, but first scp it to the server
17:06
scp /root/xorg.conf.new username@server:...
17:06
<Mip5>
okay - I can't seem to get back to my shell - though I could reboot the beast
17:06
I'd reboot the client -not the server
17:06
<alkisg>
You'd loose the xorg.conf then
17:06
<Mip5>
doh!
17:06
Okay - I haven't done it yet
17:06
<alkisg>
What if you press ctrl+alt+back space?
17:07
(as you can see I'm not really experienced either)
17:07
<Mip5>
I get ^[^H
17:07
but it doesn't restart x
17:07
<alkisg>
And with Ctrl+Alt+F1 ?
17:08
<Mip5>
Well - I get a login prompt, but I can't login with the credentials I would expect to work...
17:08
<alkisg>
Yes, you'd have to unlock the root account for the thin clients
17:08sepski has quit IRC
17:08
<alkisg>
Bah, anyway, just reboot the client, run X -configure and scp it without running X -config
17:08
<Mip5>
Good idea - brb
17:17
bummer -
17:17
I can't ssh or scp from this shell to my server
17:17
nor the other way around
17:17
I'm going to have to pick this up tomorrow =
17:17
Thanks a lot for your help.
17:18
I feel as if it's within reach - at least I know it's X related now
17:18
<alkisg>
Ok... still thinking it should be autodetected though... g'night.

Right - it does work when I boot from the ubuntu CD - but that's not how I want these machines set up

oh, I had assumed that password expiry would also use the SSH_ASKPASS, but I could defidently see why it wouldn't..

does anyone know how to correctly edit lbus_event_handler.sh to specify "allow_root" as a fuse option? if i change the add line to be '/usr/sbin/ltspfs ${WS}:/tmp/drives/${SHARENAME} "${HOME}/${DRIVEDIR}/${SHARENAME}" allow_root' it stops working :(
20:39
trying to follow scott's advice here: http://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg29623.html
20:40
i have user_allow_other in /etc/fuse.conf
20:41
this is with ltsp 4.2, and i'm trying to get fuse to allow root to access the local device mounts
