and here we go with working scanner support !
00:47
<alkisg>
Way to go stgraber! :) Will that all be in Karmic?

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...

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

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...

<maxagaz>
hi
11:05petre 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?
11:11gentgeen__ has quit IRC
11:11
<petre>
maxagaz, just a guess, but might iptables be blocking inbound requests?
11:11gentgeen__ 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 ?
11:12gentgeen__ 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?
11:44japerry 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
11:51johnny has joined #ltsp
11:52
<alkisg>
maxagaz: apart from the above serious problem, you also seem to have a configuration problem
11:57Guest60156 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
12:03ByPasS 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
12:08Guest60156 is now known as brain187
12:09maxagaz 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
12:16loather 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
12:20otavio 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...
12:23maxagaz 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.
12:25stgraber 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
12:27stgraber 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
12:36stgraber_ has joined #ltsp
12:36
<alkisg>
maxagaz: ok, do upload your (corrected) dhcpd.conf
12:36stgraber 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
12:38stgraber 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
12:43stgraber 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... ;)
13:09brain187 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
13:11john 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
13:11john 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 /
13:15Ahmuck_Sr has joined #ltsp

<maxagaz>
alkisg, ok, i'm running agin those two commands...

<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?

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

<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?

13:44
That's the last I saw: (09:37:07 μμ) maxagaz: alkisg, which is "no answer from the server, rebooting..."
13:44bobby_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
13:47alkisg has quit IRC
13:47alkisg1 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

<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

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

14:12tstafford 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 ?

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?
14:14tstafford 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

<Ahmuck_Sr>
hrm, everything is working now, but i'm not sure what i'm looking for

maxagaz: try the following hack:
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.
14:30* alkisg calls it a day... bye all.

oh. perhaps it's better i stay 32 bit ?

you put it wherever you specify options that need to make it into the driver section of your xorg.conf file

i'm not sure where that is
