Channel log from 29 April 2009 (all times are UTC)
| 00:00 | <map7> i've swapped the cables to brand new CAT6 cables and still have the same problem.
| |
| 00:00 | if i use the same cables and put both server and client into the netgear 5 port gigabit router it works nice fast for vmlinuz
| |
| 00:01 | if I put the server in the netgear, then link the netgear to the TP-LINK switch, and put the client in the TP-LINK using the same cables, that works fast as well
| |
| 00:01 | if both machines are in the TP-LINK it goes slow.
| |
| 00:03 | with the server in TP-LINK and client in netgear that goes fast
| |
| 00:03 | <johnny> i know folks have mentionedstuff like that here before
| |
| 00:03 | but .. those folks are not here right now
| |
| 00:04 | you might want to come back after 1700 GMT
| |
| 00:04 | or around that time
| |
| 00:04 | if possible
| |
| 00:04 | <map7> that makes me feel better, at least it's not just me
| |
| 00:04 | <johnny> sure.. people have issues with funny switches often
| |
| 00:04 | well.. often is overstating it..
| |
| 00:05 | but i know i've seen people talk about such things
| |
| 00:05 | let's see...
| |
| 00:05 | cheap new laptop that's better than mine
| |
| 00:05 | $400
| |
| 00:05 | (except on the display)
| |
| 00:05 | new harddrive to replace failing one $69
| |
| 00:06 | hmm...
| |
| 00:08 | <map7> 17:00GMT I don't think I'll be awake at 3am, but then again this problem is annoying me
| |
| 00:08 | <slashdotfx> how about swap the ethernet card on the server?
| |
| 00:09 | <map7> slashdotfx good suggestion, i'll give it a go.
| |
| 00:19 | hmmm, the new ethernet card in the server did the trick!
| |
| 00:20 | The cheaper and older chipset on the onboard ethernet card in the server with the TP-LINK must have issues.
| |
| 00:22 | I've hit another brick wall. After it gets the initrd.img I get the error 'mount call failed: 13'
| |
| 00:23 | The full error: http://pastie.org/462136
| |
| 00:24 | How do I clear a Stale NFS filehandle on a PXE machine?
| |
| 00:32 | intelliant has joined #ltsp | |
| 00:45 | <map7> Every post I look at in regards to clearing a stale NFS filehandle recommends restarting the nfs-client or rebooting. These don't work for a PXE client.

| 01:10 | map7 has joined #ltsp | |
| 01:34 | <slashdotfx> map7: maybe it was nfs perform poorly on the gigabit network
| |
| 01:35 | can you check if nfs is using udp? maybe you can try tcp instead
| |
| 01:36 | <map7> nfs is working fast
| |
| 01:36 | because after it got those two files it would load the OS over NFS very fast
| |
| 01:37 | download up to 6MB/s at one stage
| |
| 01:37 | but the tftp was going at 40 to 50KB/s. I think I'll put it down to 'crap onboard ethernet'
| |
| 01:38 | i have to leave, thanks for your help today

| 04:05 | <alkisg> New jaunty installation/old home dirs. On half of the user accounts, when they log off, some program breaks the logout process and the only thing that remains on their screens is their wallpaper. I can't zap the x-server and I have to restart the clients...
| |
| 04:06 | ps -ef | grep useraccount doesn't tell _me_ anything useful. How can I debug this? And, is there any new lts.conf setting to enable x zapping?

| 04:23 | <ogra> slashdotfx, i didnt even know about LDM_SYSLOG :)
| |
| 04:24 | <slashdotfx> alkisg: does lts.conf have X_OPTION_01 .. X_OPTION_12?
| |
| 04:24 | <alkisg> Eh... why me? :P Yeap, I think so...
| |
| 04:24 | <slashdotfx> I was enabling LDM_SYSLOG to debug other things, and all the sudden new problem arise from it
| |
| 04:25 | <ogra> slashdotfx, looks like sbalneav implemented that some months ago
| |
| 04:26 | <slashdotfx> ic, according to this irc logs http://www.nubae.com/logs/ltsp20081112_pg2.html
| |
| 04:27 | LDM_SYSLOG works, but if I set LDM_DIRECT=False or comment it out, client wont boot properly
| |
| 04:27 | <ogra> you mean LDM_DIRECTX=False
| |
| 04:27 | right ?
| |
| 04:27 | <slashdotfx> oh yes, sorry
| |
| 04:27 | * ogra assumes that was a typo ... | |
| 04:27 | <slashdotfx> yes it's a typo
| |
| 04:27 | <ogra> good, else it might just not read your lts.conf
| |
| 04:28 | the error handling of getltscfg sucks

| |
| 04:31 | <xbowser> Hey guys. I could use some help with ltsp-localapps. Has anyone got that running and could help me a bit?
| |
| 04:32 | Im using Lenny with ltsp from squeeze. Everything is quite fine, except for some crashes which i could'nt trace yet and localapps.
| |
| 04:34 | I got xterm installed locally, set LOCAL_APPS=True in lts.conf and I am trying to use ltsp-localapps /usr/bin/xterm, but no reaction. Even the logs on the local machine won't say anything.

| 08:50 | <chrisjrob> trying to get an asus vw195 19" 16:10 widescreen monitor working on a nvidia geforce 6150se nforce 430 onboard graphics card
| |
| 08:50 | the display does not look as crisp as it should and, after logging in, the bottom of the screen is missing
| |
| 08:51 | the monitor's auto-adjust does not correct it.
| |
| 08:51 | <zamba> i have a very old compaq desktop-system that i want to use as a thin clients.. it'
| |
| 08:51 | eh
| |
| 08:51 | it's a pIII with 128 MB ram
| |
| 08:52 | the network card supports PXE, as far as i can tell, but when i boot up it won't load the kernel
| |
| 08:52 | it boots*
| |
| 08:52 | god damn
| |
| 08:52 | is there a checklist of stuff to check to get pxe booting working?
| |
| 08:53 | <ogra> where/how does it stop booting
| |
| 08:54 | <chrisjrob> zamba: pci network card? if so, the bios probably supports pxe, but the card probably does not
| |
| 08:55 | of if it does, it probably needs the rom chip added. i usually give up at that point and use an etherboot cdrom!
| |
| 08:55 | <zamba> ogra: it tries to get dhcp information (and gets it according to syslog on the dhcpd)
| |
| 08:56 | ogra: but it never proceeds beyond that point
| |
| 08:56 | and end up saying something about filename not found
| |
| 08:56 | <ogra> that rather looks like your dhcp server isnt handing out the tftp info to it ...
| |
| 08:56 | <zamba> it's a pulse h1012 card
| |
| 08:57 | <ogra> do you have made sure there is no second dhcp server running in your network ?
| |
| 08:57 | johnb_ has joined #ltsp | |
| 08:57 | <zamba> yeah, i'm quite positive
| |
| 08:59 | <ogra> given that this card is intel chip based i would assume its doing PXE just fine ... though chrisjrob might be right, there might be two different BIOSes, one in the card and the PC BIOS itself
| |
| 08:59 | do you get any additional bootmessages that could indicate that ?
| |
| 08:59 | <zamba> how do i approach this problem then?
| |
| 09:00 | well.. i set the boot order in the system bios to boot off the network card
| |
| 09:00 | and that option is not available if i remove the card
| |
| 09:00 | <johnb_> Hello, quick question - We upgraded a test server from ubuntu 8.10 to 9.04 what is the procedure for upgrading the ltsp client images? ltsp-update-image ltsp-build-client? Thanks
| |
| 09:02 | <ogra> johnb_, wipe (or backup) /opt/ltsp/ then run sudo ltsp-build-client (i would suggest also the --copy-sourceslist option so the client chroot has the servers sources.list file available)
| |
| 09:02 | !ubuntu
| |
| 09:02 | <ltspbot`> ogra: "ubuntu" is a Debian based GNU/Linux distrubution that includes a Ubuntu specific version of LTSP. It can be found at http://www.ubuntulinux.org. to install ltsp on ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
| |
| 09:02 | <ogra> https://help.ubuntu.com/community/UbuntuLTSP/ has a lot of helpful pages

| 09:03 | Lumiere|CapsWin is now known as Lumiere | |
| 09:06 | <johnb_> thanks, ogra the upgrade documentation is a little dated on those pages "This page is specific to Ubuntu versions 8.04"
| |
| 09:09 | <chrisjrob> zamba: does it have an empty rom chip slot on the network card, possibly labelled "pxe"?
| |
| 09:10 | <zamba> chrisjrob: nope
| |
| 09:11 | i've tried stepping through the boot to see what the exact error message is, but it goes away way too fast for me to be able to pause it.. but i see something along the lines of: pxe-<some number> and then "no filename"
| |
| 09:12 | and it is in fact getting the dhcp info from the dhcpd, because i see that in the syslog
| |
| 09:12 | <chrisjrob> you clearly have a working pxe rom, so i would ignore my suggestions.
| |
| 09:12 | <zamba> Apr 29 16:04:05 fused dhcpd: DHCPDISCOVER from 00:90:27:77:2d:a8 via eth1

| |
| 09:13 | chrisjrob: maybe i need to upgrade it somehow?
| |
| 09:13 | or maybe it's incompability issues?
| |
| 09:13 | or compability issues ;)
| |
| 09:14 | <chrisjrob> i would suspect your dhcpd.conf configuration
| |
| 09:15 | as ogra says, it sounds like it's handing out an ip, but not pxelinux
| |
| 09:15 | <zamba> hold on.. snippet coming up
| |
| 09:16 | http://pastebin.com/m6bf8a1bf
| |
| 09:16 | that's the relevant configuration from the dhcpd
| |
| 09:18 | shouldn't that be enough?
| |
| 09:19 | <chrisjrob> i have a filename "/ltsp/i386/pxelinux.0";
| |
| 09:19 | <ogra> your tftp server is on 192.168.1.231 ?
| |
| 09:19 | <chrisjrob> with a preceding "/"
| |
| 09:19 | <ogra> and do you see it getting 192.168.1.117 ?
| |
| 09:20 | oh, right, what chrisjrob says
| |
| 09:20 | should have a leading /
| |
| 09:29 | dan_young has joined #ltsp | |
| 09:29 | <chrisjrob> the bottom 1cm of my display is being cut off, the monitor is 16:10 aspect, which i suspect might be the issue,
| |
| 09:29 | the graphics is an onboard nvidia geforce 6150se nforce 430 onboard graphics card
| |
| 09:29 | <ogra> nv or nvidia driver ?
| |
| 09:30 | <zamba> ogra: oh, ok
| |
| 09:31 | <chrisjrob> ogra: nv
| |
| 09:32 | <ogra> are you sure its actually using that one and not vesa ?
| |
| 09:32 | <chrisjrob> i tried stipulating XSERVER = nvidia but the screen just flashed.
| |
| 09:33 | ogra: no, if i stipulate XSERVER = vesa then it works fine, but is elongated
| |
| 09:33 | <ogra> yeah, you need to install the nvidia driver for that and the kernel module etc ... i think thats a bit of work on debian
| |
| 09:33 | <chrisjrob> ogra: i had that feeling you were going to say that
| |
| 09:34 | <ogra> and i cant say much about it ... it works totally different in ubuntu :)
| |
| 09:35 | <chrisjrob> i guess i can reallocate this monitor to a different base, and thereby avoid the problem. shame though.
| |
| 09:35 | <ogra> there are probably special xserver options you can use with nv
| |
| 09:36 | * ogra remembers IgnoreEDID from years ago when he touched an nvidia card last | |
| 09:36 | <chrisjrob> gives me something to google. thanks ogra.
| |
| 09:36 | <ogra> man nv should help too ;)
| |
| 09:37 | <chrisjrob> never knew it had a man page.
| |
| 09:38 | <ogra> every X driver does
| |
| 09:38 | <chrisjrob> we live'n'learn - good to know.
| |
| 09:40 | <ogra> man xorg.conf might also be intresting :)
| |
| 09:45 | <chrisjrob> ogra: you may recall that you tried to help me yesterday with some rdesktop disconnects, i thought it was related to the monitor going into powersave mode, and you put me onto dpms and suggested a custom xorg.
| |
| 09:45 | <ogra> right
| |
| 09:45 | <chrisjrob> it transpires that the problem is unrelated to power management
| |
| 09:45 | <ogra> oh
| |
| 09:45 | <chrisjrob> as it occurs even with dpms disabled and blanking set to 9999
| |
| 09:46 | <ogra> strange
| |
| 09:46 | <chrisjrob> the screen looks fine, but is unresponsive
| |
| 09:46 | if you switch between consoles and back again then it is just blank white
| |
| 09:47 | killing rdesktop from the the console, forces it to restart, and of course you can continue from where you left off.
| |
| 09:47 | it is literally happening every 10 minutes or so
| |
| 09:47 | <ogra> sounds like an rdesktop bug
| |
| 09:48 | though i dont have much/any experience with redsktop, there wqas an issue with the windows side that caused connections to die after a while, i remember seeing it being discussed here
| |
| 09:50 | <Gadi> doesnt sound like an rdesktop bug to me
| |
| 09:50 | sounds like a driver issue
| |
| 09:50 | twinprism has quit IRC | |
| 09:50 | <chrisjrob> there's nothing in the windows event log that i can see, although windows is pretty hopeless for logging anything useful
| |
| 09:50 | <Gadi> rdesktop disconnecting and Xserver respawning just reveals the issue with the driver
| |
| 09:50 | that the driver does not like being respawned
| |
| 09:51 | <ogra> is that as well with nvidia cards ?
| |
| 09:51 | X-TaZ is now known as X-TaZ[Pula] | |
| 09:51 | <Gadi> chrisjrob: try running ldm
| |
| 09:51 | and see if you have the same issue
| |
| 09:52 | and check the client's /var/log/Xorg*log
| |
| 09:52 | <chrisjrob> ogra: no, its a via
| |
| 09:52 | Gadi: thanks, i'll try ldm and xorg.7.log
| |
| 09:55 | i suppose i could test with XSERVER=vesa see if the problem still occurs
| |
| 09:56 | <CAN-o-SPAM> stgraber: ping
| |
| 09:56 | alkisg has joined #ltsp | |
| 09:57 | <chrisjrob> thinking about it, i have tried rdesktop to a local windows server and it was fine,
| |
| 09:57 | so it could be bandwidth related, the problematic connection is over a low bandwidth connection,
| |
| 09:58 | that said, i have 20 window's clients all connecting flawlessly over the same connection
| |
| 09:58 | <Gadi> try: rdesktop -z
| |
| 09:58 | but, I think it is a driver issue
| |
| 09:58 | <chrisjrob> already am, and "-x modem" and -P

| |
| 10:17 | <chrisjrob> Gadi: still fails with XSERVER=vesa - does that prove it isn't a driver issue?
| |
| 10:20 | <Gadi> what type of client is it?
| |
| 10:21 | <chrisjrob> its a via cn700 mini-itx
| |
| 10:21 | <Gadi> with onboard nvidia?
| |
| 10:21 | not via?
| |
| 10:22 | <chrisjrob> it is via
| |
| 10:22 | <Gadi> then why wre you setting nvidia?
| |
| 10:22 | <chrisjrob> i'm not - that was ogra, referring to an earlier conversation
| |
| 10:22 | <Gadi> oh
| |
| 10:23 | are you using openchrome drivers
| |
| 10:23 | <ogra> yeah, other prob
| |
| 10:23 | <Gadi> or via's drivers?
| |
| 10:23 | <chrisjrob> i was leaving at the default previously, so believe that would be the openchrome
| |
| 10:23 | <Gadi> and are you using VGA or DVI?
| |
| 10:23 | <chrisjrob> but am currently on vesa
| |
| 10:23 | vga
| |
| 10:23 | * Gadi has always preferred using via's drivers from their website | |
| 10:24 | <Gadi> I dont have your entire history
| |
| 10:24 | <chrisjrob> there isn't much to it...
| |
| 10:24 | we have a fresh debian lenny install
| |
| 10:25 | as phase I we are trying to configure hardware
| |
| 10:25 | and use SCREEN_07 = rdesktop to connect to our old citrix server
| |
| 10:26 | but the first client rolled out (this one) is intermittently disconnecting
| |
| 10:26 | when it disconnects, the mouse will move around the screen
| |
| 10:26 | and keyboard lights respond
| |
| 10:27 | but no interaction can take place between the input devices and the windows session
| |
| 10:27 | killing rdesktop and logging back in, resumes the session
| |
| 10:28 | <Gadi> ah
| |
| 10:28 | check the switch
| |
| 10:28 | <chrisjrob> once the problem has occurred, if you switch to another console and back again, the session is blank white
| |
| 10:28 | <Gadi> wait
| |
| 10:28 | check that
| |
| 10:29 | oh!
| |
| 10:29 | forget it - it aint the driver
| |

| 10:30 | * Gadi waves to rjune | |
| 10:30 | <Gadi> chrisjrob: are all the thin clients named the same (hostname)
| |
| 10:30 | <chrisjrob> ah!
| |
| 10:30 | i think i have the answer
| |
| 10:31 | the server has a static route back to the windows server
| |
| 10:31 | but of course that would not be used by the client
| |
| 10:31 | the client will be using the default gw
| |
| 10:31 | and i have had a few issues in that area.
| |
| 10:32 | staffencasa has joined #ltsp | |
| 10:32 | <enmi> Anyone have experience with the compaq evo t20 and ltsp-5 ?
| |
| 10:32 | <Gadi> are you using the LTSP server as a router for the client?
| |
| 10:33 | <chrisjrob> no
| |
| 10:34 | <Gadi> then, you have option routers set properly in dhcpd.conf?
| |
| 10:34 | and you have another router on the thin client subnet?
| |
| 10:35 | <chrisjrob> Gadi, option routers is pointing to our ipcop firewall
| |
| 10:35 | the clients are picking that up correctly
| |
| 10:35 | <Gadi> is that on the same subnet as the thin clients?
| |
| 10:35 | <chrisjrob> yes
| |
| 10:35 | <Gadi> then, that should be fine
| |
| 10:35 | <chrisjrob> the problem is that the route to our windows server is not through that firewall
| |
| 10:35 | <Gadi> oh
| |
| 10:35 | <chrisjrob> i have set the static route on the ipcop server
| |
| 10:35 | <Gadi> you should add the static route to the firewall then
| |
| 10:35 | yeah
| |
| 10:36 | <chrisjrob> but the performance has proved less than perfect
| |
| 10:36 | anyway, i will set the default gw to our mpls router instead
| |
| 10:37 | and re-test. if it fixes the problem, i'll go and bug the ipcop guys ;)

| 11:15 | <zamba> alkisg: not at the moment, but i should be able to fix that
| |
| 11:15 | <alkisg> ok, makes easier to see what dhcp info the client actually gets
| |
| 11:15 | E.g. filename, tftp server - and also has a command line to try staff
| |
| 11:17 | <zamba> oh, ok.. cool
| |
| 11:17 | i will try that later
| |
| 11:17 | <alkisg> zamba: do other clients boot with the same dhcpd.conf?
| |
| 11:18 | Or is that the first/only client you've tried?
| |
| 11:18 | <zamba> alkisg: it works with other
| |
| 11:19 | <alkisg> OK, try gpxe, if it boots without doing anything else it's a bios/nic combination problem

| |
| 13:24 | <droalt> on the ltsp client?
| |
| 13:24 | <_UsUrPeR_> Does an X_VIRTUAL = command exist in ubuntu 9.04
| |
| 13:24 | ?
| |
| 13:25 | the DLW 1520 works great (LVDS issue solved removed), but I still need a way to use a larger virtual monitor size without using a custom xorg.conf
| |
| 13:26 | anyone?
| |
| 13:26 | <droalt> wrong room usurper, might try #ubuntu
| |
| 13:26 | <johnny> the jaunty installer is nice
| |
| 13:26 | droalt, that is not the case
| |
| 13:26 | <alkisg> _UsUrPeR_: I see it in XS85-virtual
| |
| 13:26 | <johnny> X_VIRTUAL is a real lts.conf specific thing
| |
| 13:26 | <_UsUrPeR_> nice try :)
| |
| 13:27 | <droalt> what do you mean johnny?
| |
| 13:27 | <_UsUrPeR_> alkisg: ok, cool thanks
| |
| 13:27 | <droalt> oh usurper's question
| |
| 13:27 | <johnny> yes
| |
| 13:27 | <droalt> gotcha
| |
| 13:28 | <_UsUrPeR_> is the CONFIGURE_X = true/false bool still in there?
| |
| 13:28 | <alkisg> Nope, it's autodetected
| |
| 13:28 | <_UsUrPeR_> ORLY? nice
| |
| 13:28 | <rjune> stgraber, ogra either of you two around?
| |
| 13:29 | <stgraber> rjune: sort of around, doing a lot of other stuff
| |
| 13:30 | <rjune> does ubuntu really mix all the packages into pool for the apt server?
| |
| 13:30 | <johnny> _UsUrPeR_, i'm guessing if you specify any X_* stuff it'll generate the xorg.conf
| |
| 13:31 | <alkisg> Not all of them, e.g. color depth is usually handled as a command line parameter
| |
| 13:31 | droalt has left #ltsp | |
| 13:31 | <alkisg> (X -depth ...)
| |
| 13:33 | <johnny> ah
| |
| 13:33 | i certainly long for the day when xorg.conf is not necessary for 99% of all people
| |
| 13:34 | <_UsUrPeR_> johnny: we're almost there right now. the LVDS issue with this intel is fixed and done. Only thing left is virtual monitor sizes
| |
| 13:35 | it would be really cool if the virtual size could be managed from the client instead of specifying it on the server :/
| |
| 13:36 | P.S.: X_VIRTUAL = "xxxx xxxx" works spectacularly. kudos to whoever was responsible for the lts.conf stuff
| |
| 13:36 | <johnny> _UsUrPeR_, how will kms stuff affect the virtual sizes..
| |
| 13:36 | <_UsUrPeR_> kms?
| |

| |
| 13:41 | <alkisg> phew... X has a -retro flag to disable dontzap so that Alt+Ctrl+Backspace can be used again... ok, time for a XS96-disable-dontzap script :)
| |
| 13:41 | <johnny> where the res is set at the console..
| |
| 13:42 | _UsUrPeR_, you've seen/used the plymouth stuff in new fedora right?
| |
| 13:42 | if not.. take a gander..
| |
| 13:42 | imagine.. on boot.. you're already at the best res supported by your widescreen laptop
| |
| 13:42 | or big lcd screen
| |
| 13:43 | and then when x loads, you're already at the proper res.. and vt switching takes no time at all
| |
| 13:43 | and no flicker..
| |
| 13:43 | which is why fedora starts X on vt1 now
| |
| 13:45 | i'm not sure how virtual screens work in that scenario tho.. :)
| |
| 13:45 | hopefully it's no problem

| |
| 14:13 | _UsUrPeR_, the real problem is driver support
| |
| 14:13 | <_UsUrPeR_> yeah
| |
| 14:13 | <johnny> intel and amd are leading
| |
| 14:14 | nvidia will have it soon via nouveau
| |
| 14:14 | <_UsUrPeR_> speaking of which: do we have any locals in Korea? I want them to hold a VIA rep's child hostage until they make some video drivers that don't suck
| |
| 14:14 | <johnny> lol
| |
| 14:14 | <epsas> hmm
| |
| 14:14 | <_UsUrPeR_> I mean, openchrome is nice, but it doesn't appear to have support for dual monitors
| |
| 14:14 | <epsas> i think i need to install the nvidia binary drivers for ltsp
| |
| 14:15 | as i tried booting a terminal with a new nvidia card and I got stripey lines when it loaded X
| |
| 14:15 | <Lns> alkisg: :) I'm reading it now, though it's 120 pages, so it'll have to span some days :)
| |
| 14:18 | <johnny> epsas, that'll use a bunch more memory in the thin client
| |
| 14:18 | 30 iirc
| |
| 14:19 | <epsas> johnny - 30 megs?
| |
| 14:19 | <johnny> yes
| |
| 14:19 | and then of course.. you'll need it on the server..
| |
| 14:20 | which iirc.. means that you can't use opengl with any other non nvidia cards
| |
| 14:20 | that may or may not be a problem.. depending on how homogenous your thin clients are
| |
| 14:21 | <epsas> that's a problem
| |
| 14:21 | i guess i will just have to figure out why the XServer is giving me problems
| |
| 14:21 | that means logging onto the local linux instance and viewing logs...
| |
| 14:21 | <johnny> at least 3d is coming to nouveau soon...
| |
| 14:21 | <epsas> which means i will need a password
| |
| 14:22 | <johnny> or just set SCREEN_02=shell
| |
| 14:23 | <epsas> will that create a shell on the terminal server - or a shell on the terminal client?

| |
| 15:06 | <Lns> ah
| |
| 15:07 | <johnny> and even if i did. ssh is disabled for root

| |
| 15:11 | <johnny> jc2it, i know how to do that
| |
| 15:11 | i do that all the time too
| |
| 15:11 | this is specifically with sshfs and say mounting /usr as root, but connected via some other user
| |
| 15:11 | six2one has quit IRC | |
| 15:13 | <jc2it> oh ok, that would be an ownership/permissions issue with the file system. We do something similar with CIFS and setuid, but I have always thought it was buggy
| |
| 15:14 | <jhaig|home> I am trying to set up ltsp (using Ubuntu) on a network that already has a dhcp server. Is there documentation about how to set it up so that the client can get the dhcp information from one machine but then boot from a different one?
| |
| 15:14 | <johnny> jc2it, sshfs actually has an option called ssh_command.. i'm just trying to find what to put there
| |
| 15:14 | supposably it can listen on stdin
| |
| 15:14 | but then i'd have to put the password in the cli, which i'm trying to avoid
| |
| 15:14 | jhaig|home, sure.. just docs on ubuntu ltsp page iirc
| |
| 15:14 | or

| |
| 15:15 | <jhaig|home> Thanks
| |
| 15:15 | <johnny> a DOM?
| |
| 15:15 | <droalt2> disk-on-chip module
| |
| 15:15 | <johnny> jhaig|home, it's basically just copying the equivalent of /etc/ltsp/dhcpd.conf to whatever dhcp server you're using..
| |
| 15:16 | droalt2, why?
| |
| 15:16 | it's possible of course
| |
| 15:16 | people do that with floppies, usb keys, hard drives
| |
| 15:16 | it's no different
| |
| 15:16 | <droalt2> i have a ton of visara thin clients with 32mb DOM's
| |
| 15:16 | <johnny> tha'ts not enough
| |
| 15:17 | <droalt2> how big do they need to be?
| |
| 15:17 | <johnny> anything else would require serious customization of the image.. enough to make it not a worthwhile approach
| |
| 15:17 | droalt2, ls -lh theimage
| |
| 15:17 | hehe
| |
| 15:17 | <droalt2> the img i found is only 5.5mb
| |
| 15:18 | I grabbed it out of /var/lib/tftp
| |
| 15:18 | I grabbed it out of /var/lib/tftpboot/ltsp
| |
| 15:18 | <johnny> that's the kernel and initramfs
| |
| 15:18 | that's all
| |
| 15:18 | <droalt2> darn
| |
| 15:18 | <johnny> that's used to boot the real ltsp image
| |
| 15:19 | look in /opt/ltsp/images to see the real image
| |
| 15:19 | <droalt2> where is the ltsp img stored on the ltsp server, i have a ton of usb jump drives that I could possibly use
| |
| 15:19 | <johnny> but why?
| |
| 15:19 | there just isn't much benefit
| |
| 15:19 | and it won't just work.. you're gonna have to modify it
| |
| 15:19 | twinprism_ has quit IRC | |
| 15:19 | <droalt2> because we have over 100 of those thin clients
| |
| 15:19 | <johnny> so?
| |
| 15:20 | the real problem isn't the image.. it's the X traffic
| |
| 15:20 | <droalt2> they're small, easy to deploy, and would really help us out
| |
| 15:20 | <johnny> of course.. if you used local apps
| |
| 15:20 | why not just use em as is?
| |
| 15:20 | <droalt2> they won't pxe boot
| |
| 15:20 | <johnny> oh.. that sucks
| |
| 15:20 | <Lns> droalt2: talk to gadi when he's around re: local chroot (usb/etc) benefits. His company does that.
| |
| 15:21 | <johnny> droalt2, just put gpxe on there then
| |
| 15:21 | problem solved
| |
| 15:21 | <Lns> johnny: you're a genius =p
| |
| 15:21 | <droalt2> k i'll look into gpxe :P
| |
| 15:21 | <johnny> Lns, ?
| |
| 15:21 | are you making fun of me?
| |
| 15:21 | <droalt2> btw LNS remember that tftp timeout with a windows dhcp problem I had yesterday?
| |
| 15:22 | <Lns> johnny: gpxe on DOM, especially vs. the concept of a "thin" client having a whole OS (wince for example) on it
| |
| 15:22 | droalt2: yup
| |
| 15:22 | johnny: lol, no i'm not making fun of you =)
| |
| 15:22 | pmatulis has quit IRC | |
| 15:22 | <droalt2> i figured it out, the client somehow got confused and thought the windows dhcp server was the tftp server
| |
| 15:22 | <johnny> droalt2, but how much ram do they have?
| |
| 15:22 | * Lns hates HP for calling their thin clients "thin" | |
| 15:23 | <droalt2> so i installed a tftp server on the windows dhcp server, and coped over /var/lib/tftpboot/* to the windows tftp
| |
| 15:23 | works like a charm
| |
| 15:23 | <Lns> droalt2: yikes
| |
| 15:23 | <johnny> droalt2, you could have tried atftp.. or adjusted the block size settings
| |
| 15:23 | atftpd rather
| |
| 15:23 | <Lns> better have a mechanism in place to update the win server tftp dir every time you update the ltsp server's chroot
| |
| 15:23 | <droalt2> yea wrote that down for my regular maintenance
| |
| 15:24 | <johnny> droalt2, try what i said.. if yu want to attempt to avoid said maintenance
| |
| 15:24 | <Lns> droalt2: so you determined it was a pxe client issue and not the win dhcp server option passing?
| |
| 15:24 | <droalt2> ti's my test environment so I'm just tersting it all out
| |
| 15:24 | <johnny> Lns, i know things.. sometimes :)

| 15:24 | <droalt2> yes LNS, brought the machine with the problem to another site where everything worked and that same client had the same issue
| |
| 15:24 | it was a client issue
| |
| 15:25 | <Lns> weird
| |
| 15:25 | <droalt2> read about it that it was a known pxe issue, who knows though
| |
| 15:25 | <Lns> yeah, the different implementations of pxe (even w/just intel) are fairly buggy in some instances
| |
| 15:25 | <droalt2> seems like it only happens on built-all-in-one computers
| |
| 15:25 | <johnny> i still haveo ne machine that won't pxe boot when using dnsmasq :(
| |
| 15:25 | i use a floppy from rom-o-matic
| |
| 15:25 | <Lns> hehe, floppies
| |
| 15:26 | <alkisg> Lns: zcat /usr/share/doc/ltsp-server/lts-parameters.txt.gz|grep X_ARGS
| |
| 15:26 | <johnny> i ended up recessing the floppy really deep to stop people from stealing it
| |
| 15:26 | * Lns had to use a floppy to upgrade his BIOS in a brand new mobo the other week...had to get a disk from someone else cuz he had none on hand | |
| 15:26 | <johnny> Lns, i'm glad linux bios utiltiies are finally appearing
| |
| 15:26 | <alkisg> I once netbooted DOS to flash a BIOS :)
| |
| 15:27 | <Lns> alkisg: daring!
| |
| 15:27 | <vagrantc> i had been maintaining network bootable freedos images for flashing various BIOSes we found at freegeek, or flashing etherboot onto certain network cards.
| |
| 15:28 | but it got to be a pain to maintain.
| |
| 15:29 | <alkisg> ...is X_ARGS really an lts.conf option?
| |
| 15:29 | <Lns> I thought it was!
| |
| 15:29 | http://www.nubae.com/logs/ltsp20081116_pg1.html - find "X_ARGS" from sbalneav
| |
| 15:29 | <alkisg> I don't see it initialized anywhere, I just see "XARGS=$XARGS and something else", so I guess it's true :)
| |
| 15:30 | Lns, you made my day ):
| |
| 15:30 | :)
| |
| 15:30 | <Lns> =p
| |
| 15:30 | <johnny> ok ladies and gentlemen...
| |
| 15:30 | time to go to work..
| |
| 15:30 | where my thin clients are
| |
| 15:30 | <Lns> cheers johnny
| |
| 15:30 | ircleuser has joined #ltsp | |
| 15:30 | <alkisg> Ciao johnny
| |
| 15:30 | <johnny> not sure when i'm going to upgrade to jaunty tho .. we'll see
| |
| 15:31 | <alkisg> Lns, I think a wiki page in ubuntu for lts conf parameters would be nice...
| |
| 15:31 | * Lns goes to see a man about a horse | |
| 15:31 | <alkisg> Because lts-parameters.txt doesn't even have the half of them
| |
| 15:31 | ircleuser has quit IRC | |
| 15:31 | <johnny> alkisg, then fix lts-parameters :)
| |
| 15:31 | <alkisg> ...and I think some have different defaults in ubuntu
| |
| 15:32 | <droalt2> ty guys again for the info
| |
| 15:32 | <alkisg> johnny: sure, I offered sbalneav to do that, but I thought he said he would work on it...
| |
| 15:32 | <droalt2> i'm off to read about gxpe lol
| |
| 15:32 | droalt2 has quit IRC | |

| |
| 15:32 | <epsas> hrmm
| |
| 15:33 | so I am getting green lines when i boot this terminal up -- i even created it's own [mac-address] block in lts.conf - setting XSERVER=nv - no dice
| |
| 15:34 | <Lns> epsas: xserver=vesa ?

| 15:45 | <Lns> Can I ask a stupid question regarding ltsp-cluster, which I have no knowledge of? Basically, what's the benefit of using ltsp-cluster vs. a traditional cluster such as beowulf for clustering ltsp servers?
| |
| 15:47 | <vagrantc> Lns: beowulf wouldn't make sense for LTSP at all.
| |
| 15:47 | <epsas> i didn't know of any 'ltsp-cluster'
| |
| 15:47 | <abz______> how do i get my dhcp3-server to start at boot? don't think it is having to start it manually
| |
| 15:47 | <Lns> vagrantc: you're right - maybe i should s/ltsp/app server/ ?
| |
| 15:48 | <vagrantc> Lns: beowulf is for applications specifically written for beowulf, as i understand it ... openmosix or something is more what you're thinking of.
| |
| 15:48 | <Lns> though if, by tradition, both are the same, ltsp would be clustered along w/app server in a beowulf...is that technically viable?
| |
| 15:48 | vagrantc: ah. s/beowulf/openmosix :)
| |
| 15:49 | sorry, my slashdot slang in action
| |
| 15:49 | <alkisg> abz______: do you use network manager for the server static IP, or /etc/network/interfaces?
| |
| 15:49 | <vagrantc> maybe beowulf has gotten more vague in meaning
| |
| 15:49 | and i'm just being pedantic
| |
| 15:49 | CAN-o-SPAM has quit IRC | |
| 15:50 | <vagrantc> Lns: stgraber would be the one to ask specifically
| |
| 15:50 | cliebow has joined #ltsp | |
| 15:50 | jrock2004 has joined #ltsp | |
| 15:50 | <abz______> yeah...configured it as a static in there
| |
| 15:50 | <alkisg> in there =? which of the two?
| |
| 15:50 | <Lns> vagrantc: looks like you're right, last paragraph in http://www.beowulf.org/overview/index.html
| |
| 15:51 | <jrock2004> Does anyone have a link to some good tips for the lts.conf to help improve speed
| |
| 15:51 | <vagrantc> Lns: i think ltsp-cluster is largely for managing large collections of servers, and not so much clustering active servers ... maybe some round-robin style stuff and whatnot.
| |
| 15:52 | Lns: not sure if it handles any sort of hot failover, or if it's more round-robin + cold failover
| |
| 15:52 | <Lns> ah, a more high level 'clustering' app
| |
| 15:52 | rjune__ has joined #ltsp | |
| 15:53 | <cliebow> whjo was it working on ltsp-cluster at ubuntu-dev in Montreal...
| |

| |
| 15:59 | <alkisg> abz______: Make the connection a system one, not a per user one. Better yet, uninstall network manager and use /etc/network/interfaces.
| |
| 15:59 | <Lns> cliebow: heh, i remember that page from a link somewhere on ltsp.org about 2 years ago =)
| |
| 15:59 | <vagrantc> oh yeah, the openssi stuff
| |

| |
| 15:59 | good

| 16:00 | same diff.
| |
| 16:00 | <cliebow> wicked smart guy..
| |
| 16:00 | <abz______> alkisg - how i do that?
| |
| 16:01 | <alkisg> abz______: ehm... upload your network settings (ip/mask/dns/gateway/#nics) to pastebin so that we make you an interfaces file (unless someone has a better idea)
| |
| 16:01 | <Lns> openssi = ha+hpc?
| |

| |
| 16:04 | <cliebow> ha and some bits of hpc..(from the webpage).. circa 2005

| 16:20 | <jc2it> I have been messing with lts.conf and X_MODE_0 = 1024x768 to try to get the Screen on an HP t5545 to display correctly. Currently it is only booting to 1280x720, no matter what I set X_MODE-0 to.

| 16:28 | <jhaig|home> I have just booted a client for the first time and I have tried mounting a usb stick (which it detected automatically) but now it will not unmount without root permissions. Is it possible to configure it so that users can unmount usb without sudo? I am using LTSP on Ubuntu installed from the 'alternative' CD for 9.04.

| |
| 16:33 | <jc2it> can someone tell me what I have done wrong with X_MODE_0 in the pastebot above?
| |
| 16:34 | <alkisg> jc2it: if you happen to have intrepid, you also need CONFIGURE_X=true
| |
| 16:34 | Otherwise, I'd look at the x logs..
| |
| 16:36 | <jhaig|home> OK, digging around a bit I have found something to say that usb drives in ltsp do not need to be unmounted. This brings the question of how do I know the machine has finished writing to the drive before I pull the drive out?
| |
| 16:38 | (Also, there is a problem that I will have some ltsp clients and some real machines and users will get confused about whether they need to unmount or not)

| 16:55 | <jc2it> alksig: do I set CONFIGURE_X=true in the lts.conf or somewhere else. I haven't found any docs on it, and the sample lts.conf in LTSP Admin Ref does not use it. I will check the logs on the client.
| |
| 16:56 | <alkisg> jc2it: do you have intrepid?
| |
| 17:00 | <jc2it> alkisg: oh, I guess I should read everything you wrote. Sorry. Since I do not know what intrepid is I bet I don't have it.
| |
| 17:01 | <alkisg> jc2it: yeah, it's the previous ubuntu version, and configure_x is specific to that version. So ignore it and look at the logs...

| 17:13 | <jc2it> in the client's /var/log/Xorg.6.log file there are two lines that look interesting to me one says "(II) VESA(0): Not using mode "1024 x 768" (no mode of this name)", the next says, "(II) VESA(0): Not using mode "1280 x 1024" (no mode of this name)" when I looked through the Xorg.6.log file I saw a listing of all of the mode "names" and they are hex numbers
| |
| 17:14 | like 15e, 178, 118, etc...
| |
| 17:14 | Is that mode name what I should use instead of 1024 x768 in X_MODE_0
| |
| 17:15 | what = that
| |
| 17:31 | bobby_C has quit IRC | |
| 17:32 | <jc2it> Changing the mode names to 118 & 11b give the same result as 1024 x768 and 1280x1024
| |
| 17:34 | the line in the log that checks/displays the available modes looks like this "*Mode: 118 (1024x768)". Maybe I need it verbatim?
