<shogunx>
hola vagrantc
08:40* vagrantc waves
08:43
<shogunx>
can i impose upon you to share a brief overview of some wisdom concerning ltsping this hp client?
08:44
general strategy, method of kernel insertion, etc.
08:45
<vagrantc>
which one?
08:46* vagrantc is kind of in the middle of traveling
08:46
<shogunx>
5235
08:46
<vagrantc>
i'd been working a little with the arm-based hp t5325
08:46
<shogunx>
oh, still on the road. no worries then.
08:46
<vagrantc>
i hope to write up some more documentation when i get home
08:46
shogunx: but if there's something simple i can help with, go ahead and ask
08:47
<shogunx>
how did you get the kernel in, and i assume you cross compiled that kernel?
08:48
<vagrantc>
no, the kernel in debian stable works fine
08:48
well, mostly
08:49
shogunx: do you have access to the serial console?
08:49
<shogunx>
pin headers? i can crack it open if necessary
08:49
<vagrantc>
it's remarkably easy to open
08:50
shogunx: this proved very helpful: http://lacie.busfreaks.nl/2011/05/customizing-the-hp-t5325-with-opening-the-box/
08:50
<shogunx>
ok, so output kernel spew to ttyS0
08:50
<vagrantc>
getting into uboot is the key, and then you can network boot from uboot
08:51
http://bugs.debian.org/630113
08:51
i was able to get X with fbdev to work
08:52
<shogunx>
sweet
08:53
<vagrantc>
http://paste.debian.net/124644/
08:53
http://lacie.busfreaks.nl/2011/06/video-issues-on-the-t5325/
08:54
http://bugs.debian.org/630113
08:55
shogunx: i'd highly recommend making a bootable usb stick to unbrick the thing in case you hose uboot
08:55
i think one of the busfreaks.nl posts mentions how to do that
08:56
shogunx: i also figured out how to set uboot values from the built-in thinpro OS by getting into administrative mode and then using fw_printenv and fw_setenv or something like that
08:56
<shogunx>
did you make a arm client target in debian ltsp? or is it at the stage of "hack together a filesystem, add ltsp components"
08:57
<vagrantc>
shogunx: install ltsp-server and qemu-user-static, run ltsp-build-client --arch armel --kernel-packages linux-image-kirkwood
08:57
should work seamlessly
08:57
<shogunx>
drool. nice job
08:58
<vagrantc>
did a bunch of cross-arch qemu work this week ... also have mipsel and apparently got powerpc by fixing mipsel
08:58
so i booted a lemote yeelong with a cross-installed ltsp
08:59
<shogunx>
and this provides native binaries to the client, or the client runs a qemu instance?
08:59
<vagrantc>
i'll try and write some more comprehensive docs up when i get home ... disklessworkstations folks kindly hooked me up with one of the hp t5325 to test
08:59
shogunx: native binaries to the client
09:00
shogunx: the qemu-user-static is just for the server-side stuff ... to be able to manage the chroot cross-arch
09:00
<shogunx>
yeah, i bought one off them to fool with. i will buy more once i check it out.
09:00
<vagrantc>
so you can do: chroot /opt/ltsp/armel, and it configures binfmt-support to register arm binaries to be run with the appropriate qemu emulator
09:01
i forget if you need to manually install binfmt-support, too ...
09:01
<shogunx>
i need to set uboot on each client manually tho, eh?
09:01
<vagrantc>
yeah, that's the big downside
09:02
<shogunx>
and serial header is necessary for this?
09:02
<vagrantc>
you *might* be able to pull it off without the serial just by setting the right uboot variables from the thinpro OS
09:02
<shogunx>
oh, wait, you got tho those varianbles thrugh... ^^
09:03
<vagrantc>
but you'll want the usb stick to reflash in case you get it wrong
09:03
<shogunx>
environment variables, yes?
09:03
<vagrantc>
and once getting familiar with it, you might be able to make a network-bootable image or some such to reflash
09:03
yes, uboot environment variables
09:04
<shogunx>
ok, i can likely fill in the details on that. it would please me to be able to use these clients with the systems i am building to ship now.
09:04
<vagrantc>
it's probably easiest to have the serial for initial development, but i'm 90% certain once you figure out how to do it, you could make a usb/network boot image that could handle the flashing pretty easily.
09:04
<shogunx>
i am just not satisfied with the video performance on my geode based clients.
09:05
well, if its the equivalent of export FOO=BAR and reboot, that would be quite nice.
09:06
<vagrantc>
these might not be hugely better ... i was talking to tbm (who got the support into debian) who wasunimpressed by the video performance and was thinking of removing it from debian-installer
09:06
<shogunx>
well, the video ram is low on the geodes... thats all.
09:07
it does not like the 23" displays i got for these systems at what i would consider a reasonable resolution.
09:07
<vagrantc>
i was able to do 1280x1024 24bpp
09:07
<shogunx>
i think the ratio is different on these displays, but yeah
09:08
<vagrantc>
or 1024x768 @ 24
09:08
just to give you an idea of what's it's capable of
09:08
<shogunx>
is performance comperable to the factory graphics?
09:08
other than accel, perhaps?
09:08
<vagrantc>
it seemed less buggy than what was shipped
09:09
the drivers shipped had some artifact issues ... when i switched to fbdev it seemed much cleaner
09:09
<shogunx>
very nice
09:09
<vagrantc>
shogunx: this for some solar plans?
09:10
<shogunx>
two 5-seat solar powered networks on kiritimati (christmas island), kiribati
09:11
i have the rest of the thing built, and i have the geodes in stock, but if i can't tweak that to my liking, then i will likely get 10 of these, based on what you are telling me.
09:11
<vagrantc>
shogunx: i actually mentioned that there might be interest from people doing solar setups to tbm yesterday ... good to know i was (unknowingly) basing that on reality :)
09:12
<shogunx>
oh for sure.
09:12
if an arm will do on 3 watts what a geode will do on 6, the arm wins hands down. particularly if it can give me a little better user experience too.
09:13
<vagrantc>
also talked to bdale garbee (who works at hp), about getting more meaningful patches from hp in case there are some unmerged kernel patches that would be feasible to forward-port to newer kernels
09:13
<shogunx>
sure, i eat a couple grand on these geode clients, which do quite well with a 15 or 17" 4:3 display, but oh well.
09:13
i can find a use for them.
09:14
<vagrantc>
well, good talking, but i'd best figure out where to sleep tonight :)
09:14
<shogunx>
can i paypal you a donation for your assistance, to aid development?
09:17
<vagrantc>
i suspect we could figure something out :)
09:17
i don't use paypal, though
09:19
<shogunx>
sure, whichever way you like;)
09:25* Hyperbyte high fives shogunx
09:27* shogunx high fives, low fives, and shakes.

hey guys
14:38
i install edubuntu 11.04 with ltsp and when i try to login on thin client
14:38
only say: reponse from server, restarting
14:39
and yes i reboot server and client && update keys and image
15:02
<markit>
anti_system: I'm leaving, but just a stupid question... are you really really sure the username/password are correct? You can login with them in the server console?
15:03
s/server/server's
15:03
<anti_system>
markit yes
15:03
it my usual login
15:03
and then i try other login test
15:03
and notinhg
15:03
<markit>
'/var/log/auth.log does help?
15:04
<anti_system>
maybe
15:04
let me look
15:05
<markit>
and you area really sure sudo ltsp-update-sshkeys and sudo ltsp-update-image and reboot the thin client?
15:05
<anti_system>
yes
15:05
more than one time
15:06
<markit>
some tips: https://wiki.ubuntu.com/DebugThinClientLogin
15:06
<anti_system>
markit ever you use ltsp+edubuntu
15:06
<markit>
I'm using ltsp with kubuntu
15:06
<anti_system>
how you create users on server?
15:07
kuser or something right?
15:07
<markit>
the problem is that I'm not expert of the inside of the ltsp, so can't troublesoot too much
15:07
I use adduser from command line
15:07
but if you can login from the server is ok
15:07
(with that test user)
15:07
<anti_system>
feeling so noob after years....

15:08
and I've so much notes about various topics, that I can find nothing at the end of the day.. and use google
15:09
<anti_system>
maybe is a nox11 mode
15:09
on config files
15:10
<markit>
do you mean that could it be that logs but X session then dies?
15:10
btw, I've to run, sorry!

<Hyperbyte>
anti_system, stop being an ass.
15:58
anti_system, just be a little patient. It's weekend for crying out loud...
15:58
Your auth.log clearly says "Failed password". Meaning the password you set for 'testuser' is different than the password you're entering in ldm
15:59
Try resetting testuser's password.
16:01
<anti_system>
hyperbyte when i create a user with a tool on gnome
16:01
have to make more thing?
16:01
things*
16:02
to can login on clients?
16:06
<Hyperbyte>
Did you set a password for the user?
16:08
<anti_system>
yes
16:08
<Hyperbyte>
Type 'ssh testuser@localhost' on the server, see if you can log in that way
16:08
<anti_system>
yes i can
16:08
<Hyperbyte>
Then you should be able to log in via LDM. LDM uses ssh to connect.
16:09
<anti_system>
ldm for kde and gdm for gnome yes?
16:09
<Hyperbyte>
No
16:09
LDM is the LTSP login manager
16:10
When you boot a thin client, and get a login prompt, that's LDM
16:10
<anti_system>
ok
16:11
<Hyperbyte>
If you've been messing with the login manager on the client, then that's the reason you can't login.
16:12
<anti_system>
apt-get install ldm is the way?
16:12
lololol

No, everything is configured by default the way it's supposed to work... something you did afterwards has probably broken .... it...

16:46Damianos has joined IRC (Damianos!~Damianos@adsl-070-145-074-043.sip.cha.bellsouth.net)
16:52
<Damianos>
Having a networking issue. As per advice I received from the very helpful Hyperbyte and alkisg, I managed to get my server (edubuntu) set to rely on NetworkManager to configure interfaces. As per gnome documentation the only thing in my /etc/network/interfaces are two lines for the loopback. When I do a route -n , it shows a gateway for eth0 but no separate gateway for wlan1 I don't want to poke around too much with this thing f
16:52
fear of making a big mess.
16:53
<alkisg>
Damianos: put 0.0.0.0 in network manager as the eth0 gateway
16:53
<Damianos>
ok
16:53
<alkisg>
Damianos: also, please take a step back, and tell us why you don't want to use just eth0 for everything
16:53
I.e., for both internet and ltsp network
16:54
You may have a good reason there, or you just might not know that this is easily doable
16:57
<Damianos>
I want to keep the lab private. The rest of the school is on windows and the IT staff are very uncooperative
16:59
<alkisg>
Good reason. OK, go ahead and try the 0.0.0.0 gateway
17:01
<Damianos>
the internet is working now
17:01
trying to boot a thin client now
17:02
OMG it finally freaking works

Yes, well right now I'm on vacations in Ithaca
17:05
<Damianos>
man that's not right
17:05
you shouldn't be dealing with me while on vacations
17:05
<alkisg>
Hehe people do need to relax in a pc after relaxing all day at the beach
17:06
<Damianos>
too bad...I wanted to know if you were in the US because I will be playing in the southeast for about six weeks starting in september
17:06
<alkisg>
Playing? Do you mean living there temporarily?
17:07
<Damianos>
I was hoping that you'd be in one of the cities I'll be at so I can buy you a beer
17:07* alkisg hopes will be at the UDS in florida in late october

No, I grew up in toronto
