| |
| 00:47 | <alkisg> Way to go stgraber! :) Will that all be in Karmic?

| 03:50 | <alkisg> On standalone clients, I want to start italc when gdm starts, before the user logs in. Where do I need to put it, in Xsession.d? Or that's *after* the user logs in?
| |
| 03:56 | ...yup, seems that that's after the user logs in...

| 05:08 | <yanu> ogra: in xinerama automatic detected when xorg.conf is made on the client?
| |
| 05:10 | ogra: i did it manualy now and that works fine by copying xorg.conf-xinerama to xorg.conf at the end of /etc/init.d/ltsp-client-setup (luckily there is just one terminal in this case)
| |
| 05:11 | <alkisg> yanu: there's an X_CONF directive in lts.conf, you may want to use that one to specify a custom x file.
| |
| 05:12 | <yanu> that didn't work, the variables in lts.conf worked for ltsp-4.2
| |
| 05:12 | X_SCREEN_POS_01 = RightOf Screen00 , XSERVER_00 = mga , XSERVER_01 = mga , X4_BUSID_00 = PCI:1:0:0 X4_BUSID_00 = PCI:1:0:0
| |
| 05:13 | i tried all of these
| |
| 05:13 | <alkisg> X_CONF *does* work - if it didn't work for you you may have put it to the wrong place
| |
| 05:13 | (e.g. if you run ubuntu, you have to put it to the chroot and run ltsp-update-image after that)
| |
| 05:14 | <yanu> i tried it on debian (i suppose debian works with nfs, not nbd)
| |
| 05:15 | but where it is running now, there is ubuntu 8.04
| |
| 05:15 | <alkisg> Yes, by default debian uses nfs
| |
| 05:15 | <yanu> i didn't try it there
| |
| 05:16 | so you say, all the above variables should work ?
| |
| 05:17 | <alkisg> No. I'm saying that X_CONF works
| |
| 05:17 | So if you created a working xorg.conf, and used X_CONF in lts.conf, you should be able to run correctly without modifying the chroot
| |
| 05:18 | <yanu> ach, ok , now i get it, you mean X_CONF = /etc/X11/xorg.conf-xinerama with a working xinerama-conf, offcourse
| |
| 05:18 | <alkisg> RIght
| |
| 05:18 | And you'd put that inside the chroot, and on ubuntu, you'd also run ltsp-update-image
| |
| 05:19 | <yanu> thx, i'll try that one
| |
| 05:19 | <alkisg> Yw
| |
| 05:19 | <yanu> ok, i know the procedure

| 09:41 | <stgraber> alkisg: yeah, I plan on uploading the final LTSP on Friday
| |
| 09:41 | <alkisg> Yey! Thanks stgraber, good work :)
| |
| 09:43 | <stgraber> alkisg: btw, weren't you working on a patch for italc or its packaging ? (I thought I saw you mention that)
| |
| 09:44 | <alkisg> stgraber: sorry, I didn't have the time to complete it yet. But I do think we need a way to run italc without the autodetected clients... damn release is too soon :D
| |
| 09:45 | stgraber: how long do I have? E.g. until next weekend?
| |
| 09:45 | (no big changes, just little polishing ones)
| |
| 09:46 | <stgraber> alkisg: ideally, I'd like to get everything uploaded just after beta freeze, so probably on Friday
| |
| 09:46 | <alkisg> OK, I'll try to have it by Wed then
| |
| 09:47 | <stgraber> great, thanks
| |
| 09:51 | <alkisg> stgraber: karmic right now does have the ltsp_client_hostname fix, right?
| |
| 09:51 | Or can I test in Jaunty? (with your ppa)?
| |
| 09:53 | <stgraber> alkisg: yes, it does
| |
| 09:53 | <alkisg> Thanks, I'll try that in Karmic
| |
| 09:53 | <stgraber> my PPA has the very latest upstream snapshot (bzr from yesterday)
| |
| 09:53 | <alkisg> Hmmm and the edubuntu italc ppa has the latest italc version... so I can also use jaunty... ok
| |
| 10:01 | <Appiah> how well does italc work now?
| |
| 10:02 | <alkisg> Appiah: I'm using it a lot, and it's nice overall. I do have some complains, though, but no better solution than to use it
| |
| 10:03 | E.g. (general vnc complain) vnc should be faster on a gigabit network with no bottleneck whatsoever - no cpu limit, no network limit... :-/
| |
| 10:03 | <Appiah> hmm
| |
| 10:03 | <alkisg> Also, some times ica hangs and the clients get stuck there
| |
| 10:03 | (it remains as defunct)
| |
| 10:03 | It should be either restarted or killed completely
| |
| 10:04 | And some minor launcher inconviniences, which I'm about to look right now...
| |
| 10:07 | <Appiah> launcher?
| |
| 10:08 | <alkisg> stgraber had made an ica-launcher and an italc-launcher, which utilize avahi to autodetect italc clients
| |
| 10:08 | It's really nice & handy; it just needs some minor encanchments...

| 11:04 | <maxagaz> hi
| |
| 11:05 | petre has joined #ltsp | |
| 11:06 | <petre> I'm trying to add a public ssh key to the client so that I can ssh to the client from the server.
| |
| 11:07 | <maxagaz> i have installed ltsp on ubuntu jaunty, configured /etc/ltsp/dhcpd.conf to fit my computer which ip is 192.168.1.201, like this: http://pastebin.com/m48903ac3
| |
| 11:07 | <petre> I put the key in /opt/ltsp/i386/root/.ssh/authorized_keys, but when the client boots, the .ssh directory and authorized_keys file are not there.
| |
| 11:07 | <maxagaz> then i ran: sudo /etc/init.d/dhcp3-server start
| |
| 11:07 | <petre> Do I have to run ltsp-update-image or something to make this work?
| |
| 11:08 | <maxagaz> it works fine, but the computer plugged on the ethernet port of my server looks for a net boot, but finds nothing
| |
| 11:08 | why?
| |
| 11:11 | gentgeen__ has quit IRC | |
| 11:11 | <petre> maxagaz, just a guess, but might iptables be blocking inbound requests?
| |
| 11:11 | gentgeen__ has joined #ltsp | |
| 11:12 | <maxagaz> petre, i've never changed iptables
| |
| 11:12 | petre, how can i check this ?
| |
| 11:12 | petre, also could you tell me if my config is correct ?
| |
| 11:12 | gentgeen__ has joined #ltsp | |
| 11:13 | <maxagaz> petre, should the ip address of my server appear somewhere in /etc/ltsp/dhcpd.conf ?
| |
| 11:13 | <petre> maxagaz, what does 'iptables -L -n' show?
| |
| 11:14 | <maxagaz> petre, nothing http://pastebin.com/d3d02b813
| |
| 11:15 | <petre> maxagaz, ok, your firewall isn't the problem
| |
| 11:17 | <maxagaz> petre, another idea ?
| |
| 11:21 | <petre> maxagaz, your dhcpd.conf file looks ok, although I'm more of a Fedora person
| |
| 11:21 | so don't take my word for it.
| |
| 11:21 | <maxagaz> petre, so the ip of my server don't need to be in it, right ?
| |
| 11:22 | <petre> you could try running tcpdump on the server to at least see if the requests from the client are coming in
| |
| 11:23 | maxagaz, are you sure you don't need the 'next server' setting?
| |
| 11:23 | <alkisg> petre, I think the ltsp init script clear the root dir while booting
| |
| 11:24 | <petre> I recall a while back that next server had to be added because of a change in the default setting in ISC's dhcpd, which everyone uses.
| |
| 11:24 | But I could be mistaken.
| |
| 11:25 | alkisg, that makes sense. Is that necessary, to clear /root?
| |
| 11:25 | <alkisg> petre: I imagine they do it for security reasons, e.g. history etc
| |
| 11:30 | <maxagaz> petre, what ip addres shall i give to the "next server" ?
| |
| 11:30 | petre, this of my server 192.168.1.201, right?
| |
| 11:38 | petre, what should i grep with tcpdump to see something ?
| |
| 11:39 | <alkisg> maxagaz: what's your server ip?
| |
| 11:41 | <maxagaz> alkisg, 192.168.1.201
| |
| 11:41 | <alkisg> That's your ltsp server, and it also functions as the dhcp server?
| |
| 11:42 | How many nics does it have? 1 or 2?
| |
| 11:43 | <maxagaz> alkisg, no
| |
| 11:43 | alkisg, nic ?
| |
| 11:43 | <alkisg> nic = network card
| |
| 11:43 | <maxagaz> alkisg, only eth0 (although eth1 is diplayed by ifconfig)
| |
| 11:43 | (i just have one ethernet cad)
| |
| 11:43 | card
| |
| 11:43 | <alkisg> OK, why did you say "no"? Your ltsp server isn't your dhcp server?
| |
| 11:44 | japerry has quit IRC | |
| 11:45 | <maxagaz> alkisg, now my config looks like this http://pastebin.com/m74885f23
| |
| 11:45 | alkisg, i'm not sure to understand...
| |
| 11:45 | <alkisg> maxagaz: describe me what PCs you have, any routers, if present, and how they're all connected.
| |
| 11:46 | <maxagaz> alkisg, ps aux | grep dhcp returns this :
| |
| 11:46 | 1. /var/lib/dhcp3/dhclient-eth0.lease ...
| |
| 11:46 | 2. /var/run/dhcp3-server/dhcpd.pid ...
| |
| 11:46 | that's it
| |
| 11:47 | alkisg, i have a laptop, which is the ltsp server
| |
| 11:47 | alkisg, it's linked to a switch router, which is connected to the internet
| |
| 11:48 | then I also have another desktop computer with 2 nics, but only one is connected to the router
| |
| 11:48 | alkisg, that's it
| |
| 11:48 | <alkisg> OK. Does your switch/router have a dhcp server? (I assume yes)
| |
| 11:48 | <maxagaz> alkisg, yes it does
| |
| 11:48 | <alkisg> It won't work with 2 dhcp servers
| |
| 11:49 | You either need to disable the one in the router,
| |
| 11:49 | or switch to a customized ltsp setup, which is a *little* more difficult, and it uses dnsmasq instead of dhcp3-server.
| |
| 11:50 | <maxagaz> alkisg, i just tried to plug my desktop pc only on the only nic of my laptop, but it didn't work too
| |
| 11:50 | <alkisg> You need a crossover cable for that
| |
| 11:50 | A straight cable won't work.
| |
| 11:51 | <maxagaz> alkisg, ok
| |
| 11:51 | johnny has joined #ltsp | |
| 11:52 | <alkisg> maxagaz: apart from the above serious problem, you also seem to have a configuration problem
| |
| 11:57 | Guest60156 has joined #ltsp | |
| 11:57 | <maxagaz> alkisg, i'vz turned of the dhcp... i'll come back in a while to see about the config
| |
| 11:57 | <alkisg> maxagaz: ok
| |
| 11:58 | <Guest60156> can someone help me set up sound
| |
| 12:03 | ByPasS has joined #ltsp | |
| 12:03 | <Guest60156> i am using a kubuntu 9.04 setup installed ltsp 5.0 already! got everything up and running. i want to play sounds to the server witch is using pluseaudio. and hooked to a big tv using hdmi
| |
| 12:07 | do i have to mess with and config file
| |
| 12:08 | Guest60156 is now known as brain187 | |
| 12:09 | maxagaz has quit IRC | |
| 12:09 | <brain187> is the client set to use pluseaudio by default
| |
| 12:14 | is there a help channel for ltsp
| |
| 12:15 | <alkisg> brain187: this is the help channel for ltsp, yes
| |
| 12:15 | But in weekends not many people are here. What exactly is your question?
| |
| 12:16 | E.g. in Ubuntu, yes, ltsp clients are set to use pulseaudio by default.
| |
| 12:16 | I don't know if the scripts work in Kubuntu, though.
| |
| 12:16 | <brain187> ok heres my problem sonud works great on the server
| |
| 12:16 | loather has quit IRC | |
| 12:17 | <brain187> i just want to be able to send audio to the pluseaudio system on the server
| |
| 12:17 | <alkisg> You want to *send* audio to the server, or *get* the audio from the server and send it to the clients?
| |
| 12:18 | <brain187> i don't have a lts.conf file that i could find
| |
| 12:18 | <johnny> it doesn't need one by default..
| |
| 12:18 | so there isn't one
| |
| 12:18 | if you need one, you add it..
| |
| 12:19 | <brain187> i don't want to send any audio to the client they have no speakers
| |
| 12:20 | otavio has joined #ltsp | |
| 12:20 | <brain187> just to the server cause it has a speaker (ati hdmi audio
| |
| 12:21 | <alkisg> brain187: so you want to hear the *client* audio from the server?
| |
| 12:21 | <brain187> yes
| |
| 12:21 | <alkisg> Nice :)
| |
| 12:22 | <brain187> it's a tatto shop and we display are flash on it
| |
| 12:23 | <alkisg> Well, you would *remove* the ltsp scripts for pulse audio, I guess. :D Or just use xdmcp instead of ldm if you don't need local devices...
| |
| 12:23 | maxagaz has joined #ltsp | |
| 12:23 | <maxagaz> alkisg, i'm back without dhcp server on my router this time
| |
| 12:24 | <alkisg> maxagaz: OK. First, is your dhcp server running? sudo invoke-rc.d dhcp3-server status
| |
| 12:24 | <brain187> ok i do need local devices cause we need to be able to use our digtail camera (usb)
| |
| 12:25 | haven't figugured that out yet neither
| |
| 12:25 | <maxagaz> alkisg, Status of DHCP server: dhcpd3 is running.
| |
| 12:25 | stgraber has quit IRC | |
| 12:25 | <alkisg> maxagaz: OK, if you try to boot the client, what do you get?
| |
| 12:27 | <maxagaz> alkisg, it tries to boot from the two nics, and then boot on its own grub
| |
| 12:27 | <johnny> local devices are automatic..
| |
| 12:27 | <alkisg> !pastebot
| |
| 12:27 | <ltspbot> alkisg: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. A link to the content will be pasted in the channel.
| |
| 12:27 | <johnny> alkisg, i remember there was a bugg that i had with ubuntu that caused the sound from clients to be sent to server
| |
| 12:27 | stgraber has joined #ltsp | |
| 12:27 | <johnny> sounds like you just need to trigger that bug :)
| |
| 12:27 | <alkisg> johnny: that was with rdesktop, wasn't it?
| |
| 12:28 | <johnny> no
| |
| 12:28 | i don't use windows stuff
| |
| 12:28 | <alkisg> Ah, right, when pulse crashed locally
| |
| 12:28 | or something like that, when alsa was in use... something
| |
| 12:28 | Heh, a bug that is really a feature :D
| |
| 12:28 | <johnny> well brain187 you could try to kill pulse running on the thin client..
| |
| 12:29 | <alkisg> maxagaz: see the link for pastebot above. Put there the result of : sudo ifconfig -a
| |
| 12:29 | maxagaz: also, your /etc/ltsp/dhcpd.conf
| |
| 12:31 | <ltsppbot> "maxagaz" pasted "ltsp on ubuntu jaunty" (59 lines) at http://pastebot.ltsp.org/561
| |
| 12:34 | <alkisg> maxagaz: there's an error in the broadcast address.
| |
| 12:34 | in your (older) dhcpd.conf
| |
| 12:35 | Also, what is eth1? Your wireless?!!
| |
| 12:36 | <maxagaz> alkisg, oh right, this is my wireless
| |
| 12:36 | stgraber_ has joined #ltsp | |
| 12:36 | <alkisg> maxagaz: ok, do upload your (corrected) dhcpd.conf
| |
| 12:36 | stgraber has quit IRC | |
| 12:38 | <maxagaz> alkisg, where is it ?
| |
| 12:38 | <alkisg> /etc/ltsp/dhcpd.conf
| |
| 12:38 | <maxagaz> alkisg, sorry, my corrected dhcp.conf is after the ifconfig -a
| |
| 12:38 | stgraber has joined #ltsp | |
| 12:39 | <alkisg> Ah ok
| |
| 12:39 | maxagaz: delete option domain-name "*"; and delete next-server 192.168.1.201;
| |
| 12:40 | and delete get-lease-hostnames true;
| |
| 12:40 | After the deletions, do: sudo invoke-rc.d dhcp3-server restart
| |
| 12:40 | and try again to boot the client.
| |
| 12:42 | <maxagaz> alkisg, it still doesn't work
| |
| 12:42 | <alkisg> What is your dhcpd.conf like now?
| |
| 12:43 | <ltsppbot> "maxagaz" pasted "dhcpd.conf" (22 lines) at http://pastebot.ltsp.org/562
| |
| 12:43 | stgraber has quit IRC | |
| 12:44 | <alkisg> Seems ok. And you don't see any attempts for booting, right?
| |
| 12:44 | (i.e. trying to load pxelinux.0...)
| |
| 12:44 | Are you sure that your desktop PC supports boot from lan? Does it say anything about booting from lan while it boots?
| |
| 12:46 | (it's not enough for the bios to have a "boot from lan" option; the NIC must have a boot rom for that to work)
| |
| 12:46 | <maxagaz> alkisg, Realtek RTL8139(X)/8130/810X Boot Agent
| |
| 12:46 | <johnny> but.. if it's on onboard nic, it probably does
| |
| 12:46 | <maxagaz> alkisg, Press Shift F-10 to configure..............
| |
| 12:46 | <alkisg> maxagaz: and you have the cable connected to the onboard nic?
| |
| 12:46 | Or the other one?
| |
| 12:47 | <maxagaz> alkisg, my two computers are plugged to the router
| |
| 12:47 | <alkisg> Didn't you say that your desktop PC had 2 nics?
| |
| 12:47 | (= the ltsp client)?
| |
| 12:47 | <maxagaz> alkisg, that's true
| |
| 12:47 | <alkisg> OK, is the cable connected to the onboard one, or the other one?
| |
| 12:49 | <maxagaz> alkisg, i just replugged it on the motherboard's nic, but the result is the same
| |
| 12:49 | alkisg, (it was on the other one before)
| |
| 12:49 | <alkisg> maxagaz: OK. To debug this you'll need to try gpxe.
| |
| 12:49 | Did you say that you have grub installed?
| |
| 12:50 | <maxagaz> alkisg, on the thin client yes
| |
| 12:50 | <alkisg> Nice. You'll need to make a new menu.lst entry for gpxe.krn
| |
| 12:50 | <maxagaz> alkisg, right now i'm talking to you from the server laptop
| |
| 12:50 | <alkisg> Is that grub legacy, or grub 2?
| |
| 12:50 | <maxagaz> alkisg, grub legacy
| |
| 12:51 | <alkisg> Go there: http://rom-o-matic.net/gpxe/gpxe-git/gpxe.git/contrib/rom-o-matic/
| |
| 12:51 | Select the "linux kernel *.lkrn" format
| |
| 12:51 | Rename the result to gpxe.krn because I don't know its name :D
| |
| 12:52 | Put it to /boot/gpxe.krn
| |
| 12:52 | Then open your /boot/grub/menu.lst and put those lines near the end:
| |
| 12:52 | title Boot from network
| |
| 12:52 | kernel /boot/gpxe.krn
| |
| 12:53 | Save, reboot, and select "boot from network" from grub
| |
| 12:53 | Then press Ctrl+B to go to the gpxe command line. From there we can properly debug this...
| |
| 13:00 | (also, I hope you don't have the onboard nic disabled in the bios :) - I don't know if the boot agent would show in that case, but I thought I should mention it...)
| |
| 13:03 | <maxagaz> alkisg, for the linux kernel, i have to give it the vendor and device id, my problem is that i d'ont know from which nic to take it as lspci gives me two ethernet controllers
| |
| 13:03 | <alkisg> maxagaz: no no select "all-drivers"
| |
| 13:03 | <maxagaz> ok
| |
| 13:03 | <alkisg> This has all the drivers in one gpxe.krn
| |
| 13:04 | ...and it will detect & use both of your nics.
| |
| 13:05 | * alkisg just tried cssh, and thinks it's almost as sweet as LTSP :) | |
| 13:07 | <maxagaz> alkisg, it works :D
| |
| 13:08 | <alkisg> maxagaz: it works as in.. it boots? !!!
| |
| 13:08 | <maxagaz> alkisg, no, it boots from the grub
| |
| 13:08 | <alkisg> Heh, that was fast... ;)
| |
| 13:09 | brain187 has quit IRC | |
| 13:09 | <maxagaz> alkisg, cssh is nice, i use it sometimes too
| |
| 13:10 | <alkisg> Did you have any problems with it?
| |
| 13:10 | <maxagaz> alkisg, i can't log into it
| |
| 13:11 | alkisg, i don't have root password
| |
| 13:11 | <alkisg> maxagaz: to the ltsp login screen?
| |
| 13:11 | <maxagaz> alkisg, yes
| |
| 13:11 | john has joined #ltsp | |
| 13:11 | <alkisg> So you see the graphical login? or a text mode login?
| |
| 13:11 | <maxagaz> alkisg, i'm stupid i thought i could log with my login of the server, i forgot it's another system
| |
| 13:11 | john is now known as Guest47825 | |
| 13:12 | <maxagaz> alkisg, i see both
| |
| 13:12 | <alkisg> It's not another, it's basically your server
| |
| 13:12 | So you should be able to use a regular, non-root account from your laptop to login
| |
| 13:13 | If you can't, then maybe you changed IP to the laptop and need to run ltsp-update-sshkeys and ltsp-update-image
| |
| 13:14 | <maxagaz> alkisg, but the root of the system is in /opt/ltsp/i386, right?
| |
| 13:14 | <alkisg> That's the root of the virtual disk, which you *won't* see anywhere
| |
| 13:14 | When you login, you see the server /
| |
| 13:15 | Ahmuck_Sr has joined #ltsp | |
| 13:17 | <maxagaz> alkisg, ok, i'm running agin those two commands...
| |
| 13:22 | <Ahmuck_Sr> alkisg: r u awake today?
| |
| 13:23 | Guest47825 has quit IRC | |
| 13:25 | <alkisg> Ahmuck_Sr: most of the day... it's getting late though :)
| |
| 13:25 | <maxagaz> alkisg, when i try to login, it says "no answer from the server"
| |
| 13:25 | <alkisg> Did you have any progress with flow control?
| |
| 13:25 | stgraber_ is now known as stgraber | |
| 13:26 | <alkisg> maxagaz: sudo gedit /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 13:26 | Put there:
| |
| 13:26 | [Default]
| |
| 13:26 | SCREEN_02=shell
| |
| 13:26 | SCREEN_07=ldm
| |
| 13:26 | <Ahmuck_Sr> i'm ready for the iperf commands. i did a test last night, but not sure if i got the test right
| |
| 13:26 | <alkisg> Then reboot the client, and when you get to the logon screen, press Ctrl+Alt+F2
| |
| 13:30 | <Ahmuck_Sr> alkisg: ?
| |
| 13:30 | <alkisg> maxagaz: there, write: ssh -l some_user_in_the_laptop server
| |
| 13:30 | (leave server as it is, don't change it)
| |
| 13:30 | ...and tell me what it says, e.g. warning etc
| |
| 13:30 | Ahmuck_Sr: well, you just run iperf from all the clients together, and at the same time run iftop on the server to monitor the total bandwidth
| |
| 13:30 | <maxagaz> alkisg, great :)
| |
| 13:30 | <alkisg> If you see more than 100mbps, then flow control is off
| |
| 13:30 | If you see < 100mbps, you need to find a way to disable it.
| |
| 13:31 | Ahmuck_Sr: what?
| |
| 13:31 | <maxagaz> alkisg, there's nothing in /home
| |
| 13:31 | <alkisg> maxagaz: you managed to log in?
| |
| 13:31 | <maxagaz> alkisg, you managed it... :)
| |
| 13:32 | <alkisg> maxagaz: did it display *any* warning or message at all?
| |
| 13:32 | <maxagaz> alkisg, yes there is... Buffer I/O error on device sr0
| |
| 13:33 | <alkisg> Ugh... nope, I mean when logging in with ssh
| |
| 13:33 | ByPasS has quit IRC | |
| 13:33 | <alkisg> Now, if you try ctrl+alt+f7 and try to login from the graphical prompt, does it work?
| |
| 13:33 | <Ahmuck_Sr> iperf isn't working on the client
| |
| 13:33 | i need a iperf server side ?
| |
| 13:34 | <alkisg> Yes, you need to run `iperf -s` (I think) server - side
| |
| 13:34 | so that it listens for `iperf -c server` requests
| |
| 13:34 | <Ahmuck_Sr> k, i did that yesterday
| |
| 13:34 | exactly that
| |
| 13:34 | iperf -c server doesn't run very long
| |
| 13:34 | <maxagaz> alkisg, i can ssh to the server from the thin client now
| |
| 13:35 | <alkisg> Ahmuck_Sr: man iperf and see the time option
| |
| 13:35 | <maxagaz> alkisg, but i still get the same message from the graphical login
| |
| 13:35 | <alkisg> Hmmmm....
| |
| 13:35 | <maxagaz> alkisg, which is "no answer from the server, rebooting..."
| |
| 13:36 | <alkisg> maxagaz: that's a generic answer, it even says that when the password is wrong
| |
| 13:36 | Basically it means "ssh didn't make it for whatever reason"
| |
| 13:37 | maxagaz: I think there are some log files in /var/log, have a look there... especially the ldm one
| |
| 13:38 | (in the client, from SCREEN_02..)
| |
| 13:40 | <maxagaz> alkisg, i can see: expect saw: Permission denied (publickey, password))
| |
| 13:41 | <Ahmuck_Sr> sorry i did not see a time option. would netperf be easier?
| |
| 13:43 | alkisg1 has joined #ltsp | |

| |
| 13:44 | That's the last I saw: (09:37:07 μμ) maxagaz: alkisg, which is "no answer from the server, rebooting..."
| |
| 13:44 | bobby_C has joined #ltsp | |
| 13:44 | <maxagaz> alkisg1, i can see: expect saw: Permission denied (publickey, password)
| |
| 13:44 | <alkisg1> maxagaz: and you *did* run sudo ltsp-update-sshkeys and sudo ltsp-update-image ?
| |
| 13:45 | <Ahmuck_Sr> Ahmuck_Sr> sorry i did not see a time option. would netperf be easier?
| |
| 13:45 | <alkisg1> maxagaz: and you tried "ssh -l user server" - using "server", not an ip or something else, and then tried to login from the graphical login again with user?
| |
| 13:45 | <maxagaz> alkisg1, yes, 02:14:25 gilles@asus:/opt/ltsp/i386$ sudo ltsp-update-sshkeys
| |
| 13:46 | <alkisg1> ...and sudo ltsp-update-image?
| |
| 13:46 | <maxagaz> alkisg1, 02:15:54 gilles@asus:/opt/ltsp/i386$ sudo ltsp-update-image
| |
| 13:46 | <alkisg1> Right...
| |
| 13:46 | Ahmuck_Sr: -t, --time n
| |
| 13:46 | time in seconds to transmit for (default 10 secs)
| |
| 13:47 | Ahmuck_Sr: so that would be: iperf -t 10000 -c server
| |
| 13:47 | alkisg has quit IRC | |
| 13:47 | alkisg1 is now known as alkisg | |
| 13:47 | <maxagaz> alkisg1, i just tried this: ssh -l gilles server, which worked
| |
| 13:48 | <Ahmuck_Sr> i did: iperf -c server -d -t 600
| |
| 13:48 | 600 is like 5 miin
| |
| 13:49 | <alkisg> Ahmuck_Sr: you don't need a dual test, the client's don't send much data to the server
| |
| 13:49 | Ahmuck_Sr: then, look at the server screen, I think you'll see stats there...
| |
| 13:50 | maxagaz: if the keys are ok, and you're able to ssh from the console, I don't know why ldm wouldn't work.
| |
| 13:51 | Ahmuck_Sr: if you prefer netperf, that's the command I used: netperf -c -C -H server -l 9999 -D 10,1
| |
| 13:52 | <maxagaz> alkisg, i don't understand too, it also doesn't work from tty1

| |
| 13:53 | <alkisg> maxagaz: In the tty1 you can only login as root, and the root account is locked on the terminals, there's a procedure to unlock it but you don't really need that.
| |
| 13:53 | Ahmuck_Sr: you need to run that *from a local terminal*
| |
| 13:53 | I think you ran it from gnome-terminal, which runs on the server.
| |
| 13:54 | Ahmuck_Sr: run: ltsp-localapps xterm to get a local terminal
| |
| 13:54 | <Ahmuck_Sr> *sigh*
| |
| 13:57 | * Ahmuck_Sr mumbles | |
| 13:57 | <alkisg> Ahmuck_Sr: well, I did tell you that the other day... :-/
| |
| 13:58 | <Ahmuck_Sr> ah yes. but i didn't know how.
| |
| 13:58 | got a different problem
| |
| 13:58 | now
| |
| 13:58 | <alkisg> You didn't install iperf to the chroot?
| |
| 14:00 | <Ahmuck_Sr> yes, i did
| |
| 14:00 | got a problem with hostname
| |
| 14:00 | <alkisg> ?
| |
| 14:00 | <maxagaz> alkisg, i think i know...
| |
| 14:01 | <Ahmuck_Sr> temporary failure in name resolution
| |
| 14:01 | <maxagaz> alkisg, i was making notes from all what you taught me, when at last i can't save it because no free disk space!
| |
| 14:02 | <alkisg> maxagaz: heheheh I'd never think of that! :D
| |
| 14:02 | maxagaz: apt-get clean / autoclean etc to get some :)
| |
| 14:03 | <maxagaz> good idea
| |
| 14:03 | <alkisg> Ahmuck_Sr: who shows that? the thin client?
| |
| 14:04 | <Ahmuck_Sr> yes
| |
| 14:04 | <alkisg> What command do you give to get that error?
| |
| 14:05 | <Ahmuck_Sr> iperf command
| |
| 14:05 | brb

| 14:10 | <alkisg> Ahmuck_Sr: I meant the *exact* iperf command. E.g. if you tried "iperf my_server_name", it won't work, because there's no dns server for the clients...
| |
| 14:10 | ...you need to use the exact word "server"
| |
| 14:10 | <Ahmuck_Sr> iperf -t 10000 -c server
| |
| 14:10 | oh
| |
| 14:11 | ok
| |
| 14:11 | i was using my_server_name before ... i understand
| |
| 14:11 | <alkisg> ok

| 14:11 | <alkisg> That's why the exact commands are needed :)
| |
| 14:12 | tstafford has quit IRC | |
| 14:13 | <maxagaz> alkisg, i ran again the two commands but it still doesn't work
| |
| 14:13 | <alkisg> Do you have enough free space for the commands to complete?
| |
| 14:13 | <maxagaz> alkisg, do i have to restart the server after running those 2 commands ?
| |
| 14:13 | <Ahmuck_Sr> iftop right ?
| |
| 14:13 | tstafford has joined #ltsp | |
| 14:13 | <alkisg> maxagaz: Generating an image needs a *lot* of space, e.g. 200mb...
| |
| 14:14 | <maxagaz> alkisg, yes, i have 2 GB of free space now
| |
| 14:14 | <alkisg> Ahmuck_Sr: doesn't iperf -s also report the bandwidth?
| |
| 14:14 | tstafford has quit IRC | |
| 14:14 | <alkisg> maxagaz: no, no reboot needed except for the client of course
| |
| 14:14 | <Ahmuck_Sr> bleh, now i can't get iftop to start
| |
| 14:14 | <maxagaz> alkisg, the client detected the change automatically and thus rebooted
| |
| 14:14 | <Ahmuck_Sr> pcap_open_live(eth1): socket: Operation not permitted
| |
| 14:15 | <alkisg> Ahmuck_Sr: sudo
| |
| 14:17 | maxagaz: try again the whole SCREEN_02 / ssh thing... see the logs... I don't know what else you could do, except for dive into the sources :)
| |
| 14:17 | <Ahmuck_Sr> hrm, everything is working now, but i'm not sure what i'm looking for
| |
| 14:18 | <alkisg> Ahmuck_Sr: iftop -i eth0 or eth1 ==> you need the nic facing your clients

| |
| 14:23 | <maxagaz> alkisg, unexpected end of process: pid = 4244
| |
| 14:23 | <alkisg> 1) make a backup of /opt/ltsp/i386/etc/ssh/ssh_config
| |
| 14:23 | <maxagaz> alkisg, Process end with statut 0
| |
| 14:24 | alkisg, LDM2 works on the ip address 192.168.1.203
| |
| 14:24 | alkisg, I don't know where it took this address from
| |
| 14:24 | <alkisg> Isn't that the ltsp client address?
| |
| 14:25 | <maxagaz> alkisg, yes, true... sorry
| |
| 14:25 | <alkisg> It gets that from the laptop which now is a dhcp server
| |
| 14:26 | 2) run this: sed -i -e 's/# CheckHostIP yes/ CheckHostIP no/' -e 's/# StrictHostKeyChecking ask/ StrictHostKeyChecking no/' "/opt/ltsp/i386/etc/ssh/ssh_config"
| |
| 14:26 | echo ' LogLevel SILENT' >> "/opt/ltsp/i386/etc/ssh/ssh_config"
| |
| 14:26 | (or edit it by hand and change yes to no, etc...)
| |
| 14:27 | Then, do ltsp-update-image, and then reboot the client. If that doesn't work... well... :-/
| |
| 14:30 | maxagaz: also, if you had free space problems while building the client, maybe something wasn't installed properly, in which case you'd better run ltsp-build-client again.
