| 01:36 | <Nikopoika> i'm having sort of a problem while booting thin client... using debian etch and ltsp 5 (used this -> http://wiki.debian.org/LTSP/Howto)
| |
| 01:37 | my client starts to load kernel but then freezes with a text: "Segment <lots of numbers> does not fit in any memory region"

| 02:09 | <nf1> Hi, I just bought a monitor with integrated thin client in ti. The NIC is a 3COM and I boot using PXE. It receives the DHCP conf., the client also uncompress the kernel and starts booting but at the beginning of the boot process I got: Kernel panic - not syncing: Attempted to kill init!
| |
| 02:09 | Any Idea? When I use my notebook as thin client it boots fine.
| |
| 02:11 | <vagrantc> how much ram?
| |
| 02:11 | <cyberorg> how much memory on both machines?
| |
| 02:11 | vagrantc: heh, you beat me to it :)
| |
| 02:11 | <nf1> on the new thin client it's about 107mb of ram
| |
| 02:11 | (I know it's strange number :))
| |
| 02:12 | Burgundavia has joined #ltsp | |
| 02:13 | <vagrantc> nf1: which distro? which version of ltsp?
| |
| 02:13 | <nf1> vagrantc, Debian Sid with LTSP5
| |
| 02:14 | I tried using kernels 2.6.18-4 and 2.6.20-1, the result was the same with both kernels
| |
| 02:15 | <vagrantc> nf1: and another machine boots fine?
| |
| 02:15 | <nf1> yes
| |
| 02:16 | <vagrantc> nf1: the other machine is also using PXE ?
| |
| 02:16 | or etherboot?
| |
| 02:17 | <nf1> PXE, it's intel NIC
| |
| 02:17 | <vagrantc> nf1: only thing i can think is the NIC is not detected ...
| |
| 02:18 | nf1: so... you get the first DHCP which then loads the kernel and initrd ... yes ?
| |
| 02:18 | nf1: does it do a second DHCP request?
| |
| 02:21 | <nf1> I think it does. It gets the IP from the DHCP server, after that it starts to uncompress the kernel, then it goes initrd, then it detects some hardware (serial, usb...) after that it complains (error for one library libcrypt.so.1) and then I got the kernel panic
| |
| 02:21 | <vagrantc> nf1: that sounds like it's only doing the first dhcp request
| |
| 02:23 | nf1: i haven't tried building a sid environment in a while... maybe there's something broken in sid ...
| |
| 02:23 | nf1: you could re-build the chroot with --dist etch and see if it works ...
| |
| 02:23 | nf1: but first move aside /opt/ltsp/i386 to /opt/ltsp/i386.old or something
| |
| 02:24 | <nf1> well it's working with the other thin clients. ok I'll try build with etch. 10x. And about the second DHCP request, can you point me to where start looking.
| |
| 02:25 | <vagrantc> nf1: well, it'll spit out a bunch of information about the DHCP server and the root path and such ... lots of ip addresses ..
| |
| 02:26 | i should do a screenshot of it sometime ...
| |
| 02:26 | <nf1> in the server's /var/log/syslog I got: (let me try the pastebot for first time :))
| |
| 02:27 | <vagrantc> this whole working with other thin clients part is perplexing ...
| |
| 02:27 | maybe it's not worth re-building the whole chroot
| |
| 02:28 | nf1: do you know what module is needed for your network card ?
| |
| 02:28 | <nf1> I'm not sure for the module but the NIC is 3Com
| |
| 02:31 | <vagrantc> do you see any lines beginning with "eth0:" at boot?
| |
| 02:31 | nf1: any lines suggesting it detected your network card?
| |
| 02:32 | <ltsppbot> "nf1" pasted "thin client boot problem (kernel panic)" (6 lines) at http://pastebot.ltsp.org/134
| |
| 02:32 | <nf1> http://pastebot.ltsp.org/134 here's the dhcp request
| |
| 02:33 | <vagrantc> and you're sure that's not some other machine making that dhcp request?
| |
| 02:34 | <nf1> yes, for the test of this thin client it's only this client in the network
| |
| 02:35 | <ltsppbot> "vagrantc" pasted "ipconfig at boot" (18 lines) at http://pastebot.ltsp.org/135
| |
| 02:35 | <nf1> oops, I paste the lines for the test with the notebook, my bad, i'll paste for the client
| |
| 02:35 | <vagrantc> yeah. :P
| |
| 02:35 | valvoja has joined #ltsp | |
| 02:36 | <ltsppbot> "nf1" pasted "the right dhcp request" (4 lines) at http://pastebot.ltsp.org/136
| |
| 02:36 | <valvoja> anyone know how to get hp t5135 thin client work with linux. graphic drivers are my problem
| |
| 02:37 | <nf1> now it's the right one :)
| |
| 02:39 | <vagrantc> nf1: so ... the server's making an offer and the thin client's not seeing it or something.
| |
| 02:39 | nf1: try other ports on your switch or other cables ... or if possible, swapping out the network card.
| |
| 02:40 | nf1: try one thing at a time...
| |
| 02:41 | <nf1> I can't change the NIC it's a 19" LCD with everything integrated in it. But I'll try the cables and the switch. Thank youy for your help, I'll let you know how it goes if you're interested
| |
| 02:41 | <vagrantc> nf1: just keep posting here :)
| |
| 02:42 | <nf1> vagrantc, :) ok

| 08:46 | <vagrantc> buenas tardes
| |
| 08:46 | Gadi has joined #ltsp | |
| 08:47 | <ogra> vagrantc, hey, you just missed the edubuntu meeting ... i wanted to introduce you ;)
| |
| 08:47 | <vagrantc> ogra: well, if someone had informed me that it existed, i might have tried to attend :P
| |
| 08:48 | <Gadi> hola, amigos
| |
| 08:48 | <ogra> vagrantc, well, enjoy your travel ... no duties yet :)
| |
| 08:48 | hey Gadi
| |
| 08:48 | <Gadi> hey, ogra
| |
| 08:49 | <vagrantc> ogra: today, for less than 4 euros, bought some tasty olives and excellent cheese that would have cost well over $30 in the US
| |
| 08:49 | <Gadi> btw, ogra, since you guys are looking at speed, I notice in my testing that if I enable the logging to the server from the thin client, it makes the initial ssh connection take a long time (what with flooding of the net with packets)
| |
| 08:50 | you may want to turn off logging and see the impact?
| |
| 08:50 | <vagrantc> if it weren't for all that conquest and inquisitions and such, i wouldn't have much bad to say about spain
| |
| 08:50 | <Gadi> tho, sounds like ur packing it in over there :)

| 08:52 | <petre> Gadi: !!!!!!!!!!!!!!!!!!!!!!
| |
| 08:52 | <Gadi> hola, petre
| |
| 08:52 | <petre> one month to go to NCLS, flyers went out to all the schools in MN on Monday
| |
| 08:52 | <Burgundavia> vagrantc and I had a great chat while walking about ltsp and creating a "better upstream" model for it
| |
| 08:53 | <vagrantc> or else
| |
| 08:53 | <petre> got your plane ticket yet?
| |
| 08:53 | <Gadi> petre doesn't know me very well do he?
| |
| 08:53 | ;)
| |
| 08:53 | I'll have my plane ticket the week of at best :D
| |
| 08:54 | <cliebow_> Gadi:!!!!
| |
| 08:54 | <Gadi> but, its on my todo list today to check flights
| |
| 08:54 | <petre> oh, are you one of those who heads to the airport five minutes before departure time? ;-)
| |
| 08:54 | <Gadi> :-D
| |
| 08:54 | <ogra> Gadi, thanks for the pointer, i'll take a look
| |
| 08:54 | <petre> (been there, done that)
| |
| 08:54 | <Gadi> ogra: btw, I have a whole mess of patches for the python ldm to add features
| |
| 08:54 | bellis has quit IRC | |
| 08:55 | <Gadi> but, if you've moved to the C-based one, I'll hold off
| |
| 08:55 | <vagrantc> Gadi: well, significant portions are still in python ...
| |
| 08:55 | Gadi: it's mainly the greeter that's in C
| |
| 08:55 | <Gadi> ah, is *ldm* still a python script?
| |
| 08:55 | sbalneav has joined #ltsp | |
| 08:55 | <Gadi> ie /usr/sbin/ldm
| |
| 08:55 | <vagrantc> so far, i think so
| |
| 08:55 | sbalneav: hi!
| |
| 08:56 | <sbalneav> Morning all!
| |
| 08:56 | <Gadi> ah, well that is all I have patched
| |
| 08:56 | <petre> sbalneav: !!!!!
| |
| 08:56 | <ogra> !s
| |
| 08:56 | <ltspbot> ogra: "s" is Scotty!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
| |
| 08:56 | <sbalneav> :)
| |
| 08:57 | <petre> Gadi: what features do your patches add to ldm?
| |
| 08:58 | <ogra> Gadi, we'll keep the python wrapper for now it makes secure programming easier ... i'm fearing a bit to switch that part to C ... the greeter will se a complete rewrite
| |
| 08:59 | <Gadi> I added in: "Direct X", autologin, and separate ssh server (from SERVER)
| |
| 08:59 | "Direct X" just means that the X traffic goes straight back to the client and not through the tunnel
| |
| 08:59 | these are all switches
| |
| 08:59 | in lts.conf
| |
| 09:00 | <ogra> you mean you link the xauth file to a public generic name ?
| |
| 09:00 | <petre> oh good, autologin is a must-have for our younger kids
| |
| 09:00 | <ogra> or how do you do that ?
| |
| 09:00 | (direct X)
| |
| 09:00 | for the autologin we agreed to look at sdm's features, but if you already have something we'll take that into account as well indeed
| |
| 09:00 | <Gadi> instead of "ssh -X", I take out the "-X" part and set the DISPLAY variable in the ssh env command
| |
| 09:01 | MoL0ToV has joined #ltsp | |
| 09:01 | * Gadi knows not from sdm ;) | |
| 09:01 | <ogra> why do you need ssh there ?
| |
| 09:01 | <vagrantc> Gadi: so ... you use ssh for authentication ... slick!
| |
| 09:01 | <ogra> oh207, you want to have a second greeter and stuff ?
| |
| 09:01 | <Gadi> to launch the session and to retain localdev support
| |
| 09:01 | :D
| |
| 09:01 | J45p3r_ has quit IRC | |
| 09:01 | <petre> ogra: what's sdm?
| |
| 09:01 | <ogra> ah
| |
| 09:02 | <vagrantc> Gadi: you rock!
| |
| 09:02 | <ogra> petre, an ssh display manager similar to ldm
| |
| 09:02 | * Gadi likes to have cake and eat it too | |
| 09:02 | <vagrantc> that's way better than XDMCP
| |
| 09:02 | * ogra hugs Gadi | |
| 09:02 | <Gadi> yup
| |
| 09:02 | all easy patches, btw
| |
| 09:02 | <ogra> well, essentially it is XDMCP, isnt it ?
| |
| 09:02 | <Gadi> but with a tunnel for doing stuff like localdev
| |
| 09:02 | <ogra> yeah
| |
| 09:02 | sexy
| |
| 09:03 | <Gadi> video ROCKS, btw, with DirectX
| |
| 09:03 | <ogra> no extra work required to get localdev working and a safe tunnel :)
| |
| 09:03 | yay
| |
| 09:03 | <Gadi> you just lose the security
| |
| 09:03 | <vagrantc> which we were exploring ways to loose anyways.
| |
| 09:03 | <ogra> not as much as with plain XDMCP ;)
| |
| 09:03 | <Gadi> right
| |
| 09:03 | <vagrantc> most excellent hacks from Gadi.
| |
| 09:03 | <Gadi> Im glad you like - I thought for sure you guys would hate the idea
| |
| 09:04 | <vagrantc> what's the other stuff
| |
| 09:04 | <ogra> nah, its beautiful
| |
| 09:04 | <vagrantc> it means we don't have to support XDMCP as much
| |
| 09:04 | Stevecar has left #ltsp | |
| 09:04 | <Gadi> well, I have a LDM_USERNAME, LDM_PASSWORD, LDM_SESSION, LDM_LANGUAGE
| |
| 09:04 | if you just set LDM_USERNAME, it will use that username and empty password
| |
| 09:04 | and not use the greeter
| |
| 09:04 | <vagrantc> nice
| |
| 09:05 | <ogra> hmm
| |
| 09:05 | <Gadi> that way, you can use ssh keys
| |
| 09:05 | <vagrantc> yeah
| |
| 09:05 | <Gadi> otherwise, you have the even more unsafe option of using a password
| |
| 09:05 | <ogra> i dont like LDM_PASSWORD
| |
| 09:05 | <vagrantc> Gadi: what about an LDM_KEY or something ?
| |
| 09:05 | <Gadi> :D
| |
| 09:05 | right
| |
| 09:05 | we could do that
| |
| 09:05 | <ogra> potential security risk
| |
| 09:05 | <Gadi> LDM_USERNAME supports commands, too
| |
| 09:05 | <vagrantc> hrm?
| |
| 09:05 | <Gadi> if you do: LDM_USERNAME = "hostname|"
| |
| 09:06 | it will use the hostname of the client
| |
| 09:06 | <vagrantc> reasonable ...
| |
| 09:06 | <Gadi> (retrieved from the hostname command)
| |
| 09:06 | which is what you would need if you just have a [Default] section
| |
| 09:06 | and dont specify every ws
| |
| 09:07 | <vagrantc> sounds pretty similar to sdm's default behavior with autologin
| |
| 09:07 | ogra: sounds like Gadi has implemented some of the sdm merging :)
| |
| 09:07 | <Gadi> so, basically, autologin can be achieved with: LDM_USERNAME = "hostname|" and a bunch of symlinks of authorized_keys in user accounts with username=hostname
| |
| 09:08 | <ogra> jus mail me the branch details, we'll merge it
| |
| 09:08 | <Gadi> I figure "autologin" is almost by definition insecure
| |
| 09:08 | so, might as well make things easy
| |
| 09:08 | :D
| |
| 09:08 | <ogra> well, its in the hands of the admin ;)
| |
| 09:08 | <Gadi> right
| |
| 09:08 | <ogra> we need to provide the most secure switch for them though
| |
| 09:09 | <Gadi> these are all switches
| |
| 09:09 | <petre> who makes/maintains sdm?
| |
| 09:09 | <Gadi> by default, its same ole ldm
| |
| 09:09 | <vagrantc> petre: i'm the author of sdm :)
| |
| 09:09 | <Gadi> of course, I have just been hacking and not actually "bzr"-ing
| |
| 09:10 | <ogra> bzr it then :)
| |
| 09:10 | <vagrantc> jonas smedegaard "maintains" it in debian. though as upstream, i haven't actually done much of anything with it. unlike lessdisks.
| |
| 09:10 | <Gadi> so, it would take some time for me to break out the various changes
| |
| 09:10 | unless I can just do one branch?
| |
| 09:10 | <petre> vagrantc: tx
| |
| 09:10 | <ogra> petre, the plan is to merge sdm and ldm ... the sdm UI can then be the "low ressources" greeter for ldm
| |
| 09:11 | <petre> ogra reads petre's mind
| |
| 09:11 | <Gadi> ogra: is the sdm UI the C based one?
| |
| 09:11 | <vagrantc> Xdialog :)
| |
| 09:11 | <ogra> and ldm should gain all the features sdm has
| |
| 09:11 | hehe
| |
| 09:11 | yay for uglyness :)
| |
| 09:11 | <vagrantc> and then i can finally obselete all the projects of lessdisks.net :)
| |
| 09:11 | obsolete
| |
| 09:11 | since the domain expires soon
| |
| 09:12 | <Gadi> wouldnt Xdialog and C/GTK have practically the same resources?
| |
| 09:12 | <vagrantc> who knows till we try
| |
| 09:12 | possibly
| |
| 09:12 | <Gadi> Xdialog = C/GTK
| |
| 09:12 | :)
| |
| 09:12 | <vagrantc> depends on how it's written
| |
| 09:13 | <ogra> Xdialog == plain Xlib
| |
| 09:13 | <vagrantc> no, it's GTK
| |
| 09:13 | <ogra> you want zenity if you want gtk dialogs
| |
| 09:13 | <Gadi> no, Xdialog is GTK
| |
| 09:13 | <ogra> huh ? since when ?
| |
| 09:14 | <vagrantc> since i started using it in ... 2001 ?
| |
| 09:14 | <Gadi> trust me, we've patched it :)
| |
| 09:14 | <vagrantc> ogra: you're thinking xmessage
| |
| 09:14 | <Gadi> bbiab, folks
| |
| 09:15 | <ogra> ah, right

| |
| 09:29 | <ogra> ooooh, apparently our xsrever package supports preseeding of xserver-xorg/config/device/extra_options
| |
| 09:30 | that will get us X_MODE and X_VIDEORAM options back :)
| |
| 09:30 | <cliebow_> cool!!
| |
| 09:30 | * vagrantc smells an X_CONFIG_DEVICE_EXTRA_OPTIONS coming on | |
| 09:31 | <ogra> no, 4.2 apparently already supported X_DEVICE_OPTION_xx

| 09:31 | <ogra> i just got a mail with a patch
| |
| 09:31 | <vagrantc> heh
| |
| 09:31 | <ogra> from someone whi was to lazy to fix his lts.conf and patched ltsp-client instead
| |
| 09:31 | *g*
| |
| 09:32 | <vagrantc> we should review all the supported 4.2 options an either implement or at least document backwards compatibility bits
| |
| 09:32 | <ogra> they are bugs and should just be fixed
| |
| 09:32 | we should identify them indeed
| |
| 09:35 | <Guaraldo> sbalneav: Hi... can you halp me with this VGA compatible controller? It's a via that xorg of the ltsp cant find... lspci brings me this code: 1106:3344.
| |
| 09:37 | sbalneav: it's just working with vesa driver... but it gives me a bad definition (maximum 1024x764), but the ideal for this monitor is 1280x1024...
| |
| 09:37 | <ogra> Guaraldo, thats likely openchrome
| |
| 09:38 | <sbalneav> Guaraldo: This with Ubuntu?
| |
| 09:38 | <ogra> the openchrome driver didnt see any stable releases yet ... your best bet is to compile it from CVS and replace the via module in the client environment
| |
| 09:38 | <Guaraldo> ogra: Yep... I've found this in my researches... but I don't know how can I correct it...
| |
| 09:38 | sbalneav: Yep... Faisty
| |
| 09:39 | <ogra> thast something that applies to all ltsp versions ...
| |
| 09:39 | <Guaraldo> sbalneav: a drapper upgraded!
| |
| 09:39 | <ogra> 4.2 as well as 5
| |
| 09:39 | <sbalneav> ogra: Hmm, wonder if we can find an unofficial openchrome .deb he can install in the chroot.
| |
| 09:39 | <ogra> i'm trying to get openchrome packages for gutsy, but no promises
| |
| 09:40 | sbalneav, i dont thing there is a .deb for it ... i have a driver binary somwehere (dont ask me where) to make the 1220 go

| |

| |
| 09:42 | <Gadi> ogra: what was the upshot of all the profiling work?
| |
| 09:42 | <ogra> its compiled for feisty
| |
| 09:43 | * Gadi has been out of loop | |
| 09:43 | <ogra> Gadi, that we didnt find the big switch we need to flip
| |
| 09:43 | <sbalneav> here was the fortune I just got when I popped open my terminal
| |
| 09:43 | <Gadi> :(
| |
| 09:43 | <sbalneav> A billion seconds ago Harry Truman was president.
| |
| 09:43 | A billion minutes ago was just after the time of Christ.
| |
| 09:43 | A billion hours ago man had not yet walked on earth.
| |
| 09:43 | A billion dollars ago was late yesterday afternoon at the U.S. Treasury.
| |
| 09:43 | <ogra> i'm waiting for jammcq t tell the last results
| |
| 09:44 | <Gadi> ogra: do you do all of your tests with logging enabled to the server?
| |
| 09:44 | <ogra> i'm down to 1:30 boottome for the e2300 here though ... but thats with a static xorg.conf
| |
| 09:44 | yes
| |
| 09:44 | <Gadi> hmm...
| |
| 09:44 | <ogra> i dont log in
| |
| 09:44 | we only measure boospeed
| |
| 09:44 | *boot
| |
| 09:44 | <sbalneav> 1:30? That's an improvement
| |
| 09:44 | <ogra> sbalneav, using XDMCP and a static xorg.conf
| |
| 09:44 | <Gadi> still, it logs every step over the network
| |
| 09:45 | perhaps that introduces some delay?
| |
| 09:45 | <sbalneav> ogra: See? XDMCP: Still good for something :)
| |
| 09:45 | <Gadi> noticeable on slower clients
| |
| 09:45 | <ogra> Gadi, we can move the start of logging into ltsp-client after X is up
| |
| 09:45 | thats no prob
| |
| 09:45 | sbalneav, yes, and with Gadis patch even localdev will work right away
| |
| 09:46 | <sbalneav> What's gadi doing? Haven't seen this patch...
| |
| 09:46 | <ogra> so many bright ltsp devs and nobody had the obvious idea Gadi had ...
| |
| 09:46 | * ogra hangs his head in shame | |
| 09:46 | <Gadi> hey
| |
| 09:46 | what does that make me?
| |
| 09:46 | y'know you miss 1 trip to Spain....
| |
| 09:46 | <ogra> sbalneav, removing -X from the ssh stanza and exporting DISPLAY with the server ip :)
| |
| 09:47 | so you have ssh auth in the backend, using the tunnel etc but on top its XDMCP
| |
| 09:47 | <sbalneav> lol
| |
| 09:47 | <ogra> sooo trivial
| |
| 09:47 | <Gadi> my ideas are borne out of something that many devs lack - really demanding customers
| |
| 09:47 | * ogra bonks his head against his whiteboard | |

| |

| |
| 09:48 | * ogra cheers | |
| 09:48 | <sbalneav> ok, so here's the question.
| |
| 09:48 | <Gadi> just put me in the credits somehwere under the barber of seville
| |
| 09:49 | <ogra> haha
| |
| 09:49 | <vagrantc> sbalneav: we might even not need to support the localdev for both ssh and XDMCP
| |
| 09:49 | <ogra> right
| |
| 09:49 | <Gadi> indeed not
| |
| 09:49 | <sbalneav> Wonder if we can script password expirey.
| |
| 09:49 | <vagrantc> i mean, we should explore the idea if it's easier
| |
| 09:49 | <sbalneav> via the ssh.
| |
| 09:49 | <ogra> sbalneav, ++
| |
| 09:49 | <vagrantc> there were some positive things in the idea
| |
| 09:49 | <ogra> and smartcards
| |
| 09:50 | <Gadi> I can give you smartcard support in one line
| |
| 09:50 | <sbalneav> Oh, I'll drop my stuff in an instant, IF I can get password expires.
| |
| 09:50 | <ogra> i get requests once every quater for smartcard support
| |
| 09:51 | <sbalneav> Gadi: Did I ever tell you how much I love you? :)
| |
| 09:51 | <Gadi> but, then that's trivial too:
| |
| 09:51 | -I smartcard_device
| |
| 09:51 | Specify the device ssh should use to communicate with a smartcard
| |
| 09:51 | used for storing the user’s private RSA key.
| |
| 09:51 | (from man ssh)
| |
| 09:51 | personally, what I would like to see is a switch in ldm to tunnel *everything* or *nothing*
| |
| 09:51 | but, that's a bit more work
| |
| 09:51 | :-D
| |
| 09:52 | gepatino has joined #ltsp | |
| 09:52 | <Gadi> everything = localdev, sound, X, ...
| |
| 09:52 | I do have a request from you guys, tho
| |
| 09:53 | eh, nm
| |
| 09:54 | I just talked myself out of that
| |
| 09:54 | * Gadi is a bit crazy these days | |
| 09:54 | <ogra> i dont see the real need to tunnel *everything*
| |
| 09:54 | <Gadi> need coffee
| |
| 09:54 | yes, but I do
| |
| 09:54 | :)
| |
| 09:54 | see, we have slightly different needs from LTSP
| |
| 09:54 | <ogra> especially since it puts a lot extra load on the client
| |
| 09:55 | <Gadi> heh, that's not what you said about X
| |
| 09:55 | ;)
| |
| 09:55 | well, if at least localdev could be tunneled
| |
| 09:55 | <ogra> yeah... but sounds ?
| |
| 09:55 | <Gadi> sound, I suppose is optional
| |
| 09:55 | <ogra> right
| |
| 09:56 | <Gadi> even NX sound isn't fantastic on far servers
| |
| 09:56 | most protocols for that matter
| |
| 09:56 | <ogra> they dont use pulseaudio ;)
| |
| 09:56 | <Gadi> but, localdev should still work
| |
| 09:56 | <ogra> i havent seen any bad things wth pulse yet
| |
| 09:56 | *with
| |
| 09:56 | <Gadi> well, if I connect to your server in Germany, ogra, pulse would still not fair well when tunneled
| |
| 09:57 | <vagrantc> it would be nice if everything would work across NAT
| |
| 09:57 | <Gadi> indeed
| |
| 09:57 | for me, it becomes even more than a nicety
| |
| 09:57 | we would just need something to manage ports
| |
| 09:57 | <vagrantc> and pumping everything through ssh would make NAT an option
| |
| 09:57 | <ogra> well, with the option to run ldm as standalone login manager it might become an issue
| |
| 09:58 | <Gadi> ?
| |
| 09:58 | <ogra> so send your patches :)
| |
| 09:58 | <Gadi> thx
| |
| 09:58 | but, my patches don't always get merged :P
| |
| 09:58 | specially if it is not inline with Ubuntu's LTSP mission statement
| |
| 09:58 | <ogra> even though i would still prefer to be able to do fine grained switching per feature
| |
| 09:59 | <Gadi> indeed
| |
| 09:59 | I always make switches
| |
| 09:59 | I am an electrical engineer, remember?
| |
| 09:59 | <ogra> Gadi, there will be another guy caring for ubuntu ltsp soon ... he is more on your side ;)
| |
| 09:59 | <Burgundavia> heh
| |
| 09:59 | <Gadi> what?
| |
| 09:59 | why?
| |
| 09:59 | <Burgundavia> the very talk vagrantc and I had while exploring the wonderful city of Madrid
| |
| 09:59 | <ogra> configurability uber alles ;) debian compliance as well :)
| |
| 10:00 | * vagrantc stares blankly | |
| 10:00 | <ogra> heh
| |
| 10:00 | <highvoltage> debian ftw
| |
| 10:00 | <Gadi> *sigh* more corporate politics... whats an engineer to do?
| |
| 10:00 | <vagrantc> free the world?
| |
| 10:00 | yeah!
| |
| 10:00 | * sbalneav potters around with expired accounts to figure out ssh behaviour | |
| 10:00 | <Burgundavia> convert to communism
| |
| 10:01 | <Gadi> speaking of corporate politics, back to work...
| |
| 10:01 | <vagrantc> sbalneav: i think with password expiry we'd need to properly implement a real ssh-askpass
| |
| 10:01 | i *think* that would work
| |
| 10:01 | <sbalneav> right
| |
| 10:01 | <ogra> Gadi, i'm having a very closed focus on ubuntu ... vagrantc will take more of the other stuff into account and (hopefully) push me in the right directions
| |
| 10:02 | <Burgundavia> that might be better phrased as "I have a very narrow focus", ogra?
| |
| 10:02 | <Gadi> so, debian chroots in my future?
| |
| 10:02 | <ogra> yeah
| |
| 10:02 | Gadi, no the same chroots for all deb based systems ;)
| |
| 10:02 | <vagrantc> it's about time to do another debian fork.
| |
| 10:02 | <Gadi> heh
| |
| 10:02 | *sigh*
| |

| 11:28 | <ogra> hmm, i'm just testing gadis patch
| |
| 11:28 | somehow ssh -X is a lot faster on the e2300
| |
| 11:29 | i cant even drag my firefox win around
| |
| 11:33 | <sutula> vagrantc: On the Debian Etch version, ltsp-server, are there extra tricks to getting X parameters passed from lts.conf to the client's X session? I couldn't get X_MODE_0 = 1280x1024 and X_HORZSYNC = "30-70" to work last night
| |
| 11:34 | * sutula didn't try that hard, but is wondering if something is different with that setup | |
| 11:34 | * vagrantc looks | |
| 11:34 | <vagrantc> hrm.
| |
| 11:35 | <ogra> X_HORZSYNC doesnt work without X_VERTREFRESH
| |
| 11:35 | <vagrantc> apparently you need to set both X_HORZSYNC and X_VERTREFRESH for either to work
| |
| 11:35 | * vagrantc suspected it, but needed to confirm | |
| 11:35 | <vagrantc> ogra: finally, you one-up me! :P
| |
| 11:35 | <ogra> :)
| |
| 11:36 | <sutula> vagrantc: OK...also are they picked up only if I use ldm, or would they be effective with SCREEN_07 = startx
| |
| 11:36 | <vagrantc> sutula: those should work with either
| |
| 11:36 | <sutula> vagrantc, ogra: Thanks much
| |
| 11:36 | <vagrantc> por supuesto
| |
| 11:37 | <ogra> hmm, i'm not really convinced gadis patch is as good as it looks like
| |
| 11:38 | dragging windows around gets this little thingie to 100% CPU usage
| |
| 11:38 | <vagrantc> well, if the patch is bad, we can re-engineer the idea
| |
| 11:38 | oh really?
| |
| 11:38 | <ogra> yeah
| |
| 11:38 | it still uses the tunnel for all data, but without using the X proxy from ssh
| |
| 11:39 | <vagrantc> i don't see how that could be.
| |
| 11:39 | <ogra> it will help a lot with multimedia on powerful clients but doesnt seem really useful as default
| |
| 11:39 | <vagrantc> definitely not as default
| |
| 11:40 | <ogra> he still calls ssh user@server "DISPLAY=ip:6 /etc/X11/Xsession"
| |
| 11:40 | <vagrantc> yes... and?
| |
| 11:40 | <ogra> which means the whole network traffic is still encrypted
| |
| 11:40 | <vagrantc> no
| |
| 11:40 | it shouldn't be
| |
| 11:40 | <ogra> ssh -X opens a proxy on both sides
| |
| 11:40 | <vagrantc> if you skip the -X , it shouldn't make use of the proxy
| |
| 11:41 | <ogra> so localhost:11 on the server is redirected to :6 on the client
| |
| 11:41 | it doesnt
| |
| 11:41 | but all the application data goes still through the tunnel
| |
| 11:41 | <vagrantc> hrm.
| |
| 11:41 | i suspect we can get it working
| |
| 11:41 | some trivial mistake or something
| |
| 11:42 | <ogra> i dont think it can work the way he implemented it
| |
| 11:42 | by design
| |
| 11:42 | it might be another drawback of the e2300 though
| |
| 11:42 | <vagrantc> well, i'll explore it
| |
| 11:43 | <ogra> i'll test with a real client
| |
| 11:43 | this 200Mhz CPU that also does graphics and sound isnt really great ...
| |
| 11:43 | i'm not convinced at all by it ...

| 11:51 | (usually thats done by adding him/her to the fuse group)

| |
| 11:59 | <highvoltage> ogra: I do inded
| |
| 11:59 | *indeed
| |
| 11:59 | <ogra> looks like sunrpc still uses tcp even on udp -o nolock mounted nfsroots
| |
| 11:59 | <highvoltage> I wonder why
| |
| 11:59 | <ogra> thats quite weird
| |
| 11:59 | well, it shouldnt
| |
| 12:00 | beyond that nbd uses tcp indeed
| |
| 12:00 | so from the point on where network swap comes up you will see tcp traffic
| |
| 12:00 | but thats later in the loop than where we saw it in sevilla
| |
| 12:01 | <highvoltage> yes, and we saw lots of tcp traffic even with nbd disabled
| |

| |
| 12:02 | <ogra> yeah
| |
| 12:02 | its a client side thing
| |
| 12:03 | in any case ..
| |
| 12:03 | i did measure the vmlinuz and initramfs speeds btw ...

| 12:03 | <ogra> tsp 4.2 kernel enters the initramfs 11secs earlier
| |
| 12:04 | <cy_coe> On the server are two, but the client has just one
| |
| 12:04 | <ogra> they both need the same amount for working through the initramfs
| |
| 12:05 | <highvoltage> ogra: have you tried different packet sizes? According tosection 4 on http://www.auug.org.au/publications/auugn/vol16no1/sunPaper.html it seems to make quite a big difference
| |
| 12:05 | (block sizes, even)
| |
| 12:06 | ogra: ignore that, it's probably irrelevant
| |
| 12:06 | * highvoltage is just pulling straws | |
| 12:06 | <ogra> i used both with the default value ... which is rsize and wsize = 32768
| |
| 12:07 | it helps to set the values to 4096 ... but as long as both use the same vals it doesnt matter
| |
| 12:07 | <highvoltage> cy_coe: ok, that sounds fine. I'm a bit out of it atm, hang around, i'm sure someone will be around soon that will be able to help you
| |
| 12:07 | <cy_coe> ok

| 15:42 | <Guaraldo> mattwalston: I use NX (NoMachine)... But u must have a server part running on server and a client part on the client. An ssh access is needed too...
| |
| 15:42 | <jumako> e.g.: Xnest -xkbmap /etc/X11/xkb -ac -geometry 1024x768 -query 192.168.0.11 :8 -fp tcp/192.168.0.11:7100
| |
| 15:43 | <mattwalston> Guaraldo, what protocol is that? vnc?
| |
| 15:43 | jumako, I thought ltsp did not use xdmcp
| |
| 15:43 | <Guaraldo> no... it uses ssh and nx...
| |
| 15:43 | <jumako> it works (for me with ltsp 5)
| |
| 15:44 | <Guaraldo> mattwalston: ltsp just exist becouse xdmcp...
| |
| 15:45 | mattwalston: like old Unix mainframes!
| |
| 15:45 | <sepski> ltsp5 uses ldm across ssh, i dont think it uses nx by default (altho it can) and if you install eg kdm it can use xdmcp too
| |
| 15:45 | <mattwalston> sepski, thanks
| |
| 15:46 | * Guaraldo user ltsp 4.2... yet! But it will not be for much time... | |
| 15:46 | <mattwalston> my observation is that it does a great job at providing access from pxe booted clients, it would be nice to have a canned way to install a package on a laptop or desktop and be able to connect to your ltsp system over the vpn
| |
| 15:47 | <sepski> mattwalston, if i want access to the desktop from outside i just install freenx on the ltsp desktop server.
| |
| 15:47 | bronze has joined #ltsp | |
| 15:47 | <mattwalston> sepski, is freenx an x server or what?
| |
| 15:48 | <sepski> and a tiny webserver with the nxapplet (nxclient on the webpage) then i can just surf to a url and get the client up (as long as the webbrowser has java)
| |
| 15:48 | mattwalston, it's a compression protocol and can be used on x vnc and rdp, but i use it on X and it gives me kde desktop.
| |
| 15:49 | <mattwalston> sepski, oh ok
| |
| 15:49 | <sepski> mattwalston, i have used it from cyprus to norway on a 33k6 line. and it was useable. vnc was plain hopeless.
| |
| 15:49 | <mattwalston> sepski, impressive... i will be reading up on it
| |
| 15:49 | Q-FUN1 has quit IRC | |
| 15:50 | <sepski> ofcourse you realy need it tho. since you can just use ssh -X -C host, and get the one or two app you need.
| |
| 15:50 | you usualy dont need the whole desktop anywa
| |
| 15:51 | <mattwalston> sepski, it is for a non-technical user, we are replacing nt with rdp and some of the managment likes to be able to login
| |
| 15:51 | literally I had an email from our president wanting me to set-up gotomypc, but we don't have a single windows machine
| |
| 15:52 | <sepski> mattwalston, then nx can be just that
| |
| 15:52 | <mattwalston> sepski, thanks
| |
| 15:52 | <sepski> mattwalston, use freenx on the desktop server and nxclient on windows laptops. if you need access from random machines or netcafes you can set up nxplugin on a webpage.
| |
| 15:53 | <mattwalston> sepski, thanks

| 16:42 | <davidj> A big potential client (~20,000 clients at 6 locations)
| |
| 16:42 | <jammcq> wow
| |
| 16:42 | that's alot of clients
| |
| 16:42 | <davidj> yes, 'tis.
| |
| 16:43 | At the moment they use norton ghost or similar to reimage machines
| |
| 16:43 | Sometimes three or more times a week.
| |
| 16:43 | <jammcq> wow, that's just nonsense
| |
| 16:43 | <davidj> Also, they throw machines away every 3 years without fail or exception.
| |
| 16:45 | It's the craziest setup I've ever seen. They have 299 "standard apps", everyone's in active directory, and all servers are in a single closet in a single building.
| |
| 16:45 | They consider switches to be servers, so they only use hubs at remote locations.
| |
| 16:46 | But they do have top of the line cisco equipment

| 18:51 | * jbrett jumps up and down at *finally* getting "ltsp-build-client" to complete successfully on his ubuntu feisty machine. | |
| 18:52 | <jbrett> *man* that script is fragile (and irritating, since it makes me remove /opt/ltsp/i386 every *$#&@^$ time it fails to complete).
| |
| 18:52 | <jammcq> oh yeah, like rm -rf /opt/ltsp/i386 is REALLY difficult :)
| |
| 18:52 | <dberkholz> heh, if it only deleted that automatically it would be great and perfect
| |
| 18:53 | <jammcq> but then, you could accidentally delete a production one
| |
| 18:53 | <jbrett> jammcq: no, but waiting for it to re-download all the packages *for the thirteenth time* is pretty irritating.
| |
| 18:53 | <jammcq> what's the problem causing it to fail?
| |
| 18:53 | <dberkholz> why would you be running ltsp-build-client on it if it already existed?
| |
| 18:53 | <jbrett> i.e. it's that the script *requires* me to remove it that's irritating.
| |
| 18:53 | <jammcq> dberkholz: dunno, but it could easily happen
| |
| 18:54 | <jbrett> jammcq: the first problem was that it didn't like the fact that I set "LANG=C" in my .bashrc
| |
| 18:54 | <jammcq> it didn't like that? Seems like a bug report should be filed
| |
| 18:54 | <jbrett> jammcq: the second problem is that I'm inside a firewall, and it couldn't resolve the hardcoded ubuntu mirror.
| |
| 18:55 | <jammcq> hmm, another but report
| |
| 18:55 | <jbrett> I can't remember what the third problem was..
| |
| 18:56 | oh, and the final/fourth problem was that something was out-of-sync with a mirror, and it thought a package was unsigned.
| |
| 18:56 | on all of these errors, it just failed, and required me to remove the i386 directory and start completely from scratch :o(
| |
| 18:57 | <jammcq> ok, so go file bug reports, to prevent these things from happening to the next guy
| |
| 18:57 | * jbrett is working on that.. | |
| 18:57 | <jammcq> cool
| |
| 18:57 | <jbrett> jammcq: I just had to vent here first ;o)
| |
| 18:58 | * jbrett feels his blood pressure slowly lowering ;o) | |
| 18:59 | <jbrett> now that it's working though, it's pretty schweet :o)
