| 08:33 | <markit> hi, I've a 2 nic interface server, one for ltsp cliens and one for wan (router) connection. I want to limit sshd to permit log of only one username from wan, but without preventing ltps clients log :) Is it possible? Don't want to put a long list in AllowUsers directive with all the ltsp users
| |
| 08:33 | wondering if I can tell to let everyone pass if coming from one interface (or subnet), while limiting to the specific username if coming from the other interface

| 15:11 | <myjess> hello again.
| |
| 15:13 | I was wondering if anyone knows how to change whatever needs to be changed in chroot to make a usb sound dongle the default one, and also to make the usb dongle the default sound output.
| |
| 15:15 | I have already got the sound dongle as default using alsa-base, and created an /etc/asound.conf file with pcm and ctl point to HW 0. But every time I boot the client
| |
| 15:15 | I have to change the sound preferences - output tab to point to USB.
| |
| 15:15 | Thanks.

| 15:18 | <myjess> I am running karmic by the way, so maybe all I have done is no good, since I think it was all for alsa.

| 18:44 | <langvann_> Anyone awake ?
| |
| 18:45 | <alkisg> Hi
| |
| 18:46 | <langvann_> Hi. Im trying to get ltsp up and running
| |
| 18:46 | everything seems fine on the server side.. however, when i try to boot up the client, i get an error telling me that tftp cannot connect
| |
| 18:46 | <alkisg> And? any problems?
| |
| 18:46 | Ah. Distro/version?
| |
| 18:47 | <langvann_> Ubuntu 10.4 server <- server and ubuntu 10.4 Desktop -> client
| |
| 18:47 | <alkisg> ok, on the server, try the following commands:
| |
| 18:47 | sudo netstat -nap|grep :69
| |
| 18:48 | <langvann_> nothing
| |
| 18:48 | <alkisg> ok, next: cat /etc/default/tftpd-hpa
| |
| 18:48 | !pastebot

| |
| 18:49 | BWMerlin has joined #ltsp | |
| 18:49 | <alkisg> OK you have a typo in DAEMON but it doesn't matter because it's commented out
| |
| 18:49 | <langvann_> I also have tftp 69/udp
| |
| 18:49 | <alkisg> Where? in netstat?
| |
| 18:50 | <langvann_> in /etc/services.. not sure if it matters
| |
| 18:50 | <alkisg> Nah
| |
| 18:50 | Next: grep tftp /etc/inetd.conf
| |
| 18:50 | <langvann_> nothing
| |
| 18:50 | <alkisg> OK. Seems good so far.
| |
| 18:50 | dpkg -l tftpd-hpa | grep ^ii
| |
| 18:51 | <langvann_> ii tftpd-hpa 5.0-11ubuntu2 HPA's tftp server
| |
| 18:51 | <alkisg> sudo start tftpd-hpa
| |
| 18:51 | <langvann_> it is started
| |
| 18:51 | <alkisg> Try booting the client
| |
| 18:51 | <langvann_> PXE error, tftp cannot open connectino
| |
| 18:52 | <alkisg> Try again the netstat command: sudo netstat -nap|grep :69
| |
| 18:52 | It should be showing the process now
| |
| 18:52 | <langvann_> yes
| |
| 18:52 | it does
| |
| 18:53 | gonna try now
| |
| 18:54 | same error on the client
| |
| 18:54 | <alkisg> ok, next: cat /etc/ltsp/dhcpd.conf (in pastebin)
| |
| 18:54 | <langvann_> http://ltsp.pastebin.com/0byn8LVV
| |
| 18:55 | <alkisg> filename "/opt/ltsp/i386/boot/pxelinux.0"; ==> that's not right in a normal installation
| |
| 18:55 | Change it to /ltsp/i386/pxelinux.0
| |
| 18:56 | and, the next one, change it to: /ltsp/i386/nbi.img
| |
| 18:56 | if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
| |
| 18:56 | filename "/ltsp/i386/pxelinux.0";
| |
| 18:56 | } else {
| |
| 18:56 | filename "/ltsp/i386/nbi.img";
| |
| 18:56 | }
| |
| 18:57 | Then restart the dhcp server: sudo invoke-rc.d dhcp3-server restart
| |
| 18:57 | <langvann_> root-path is correct?
| |
| 18:57 | <alkisg> Yes, but it isn't used. It's only for nfs.
| |
| 18:59 | Leave it though, as some clients will not accept a pxe offer if it doesn't contain a root path (that's rare, but it happens)
| |
| 18:59 | <langvann_> ok
| |
| 18:59 | so i restarted the dhcp server
| |
| 18:59 | but nothing happened on the client
| |
| 18:59 | same error
| |
| 19:00 | <alkisg> ok, next: ls -lha /var/lib/tftpboot/ltsp/i386/pxelinux.0
| |
| 19:00 | <langvann_> -rw-r--r-- 1 root root 15K 2010-05-15 22:11 /var/lib/tftpboot/ltsp/i386/pxelinux.0
| |
| 19:01 | <alkisg> Unless some mistake was made, your server seems OK now.
| |
| 19:01 | Does it have some firewall?
| |
| 19:01 | <langvann_> No, not intentionally atleast
| |
| 19:02 | <alkisg> OK. Is dhcpd running? sudo invoke-rc.d dhcp3-server status
| |
| 19:02 | <langvann_> its running
| |
| 19:02 | <alkisg> How many nics do you have, and what are their IPs?
| |
| 19:02 | <langvann_> would you be comfortable with helping over ssh ?
| |
| 19:02 | <alkisg> (ifconfig -a)
| |
| 19:02 | <langvann_> I only have one nic, ip adress is 192.168.1.6
| |
| 19:03 | <alkisg> langvann_: sure - vnc would be better, do this:
| |
| 19:03 | sudo apt-get install x11vnc
| |
| 19:03 | <langvann_> Dont have a grapical interface on the server
| |
| 19:03 | <alkisg> ah ok
| |
| 19:03 | Then ping me with the ssh details...
| |
| 19:09 | pmatulis has joined #ltsp | |
| 19:16 | <langvann_> 02:15 <alkisg> Erm what? Why don't you put them as usb drives instead?
| |
| 19:17 | Because i had to use the equipment I already had
| |
| 19:17 | The username and the passwords are the same for the client and server?
| |
| 19:17 | <alkisg> Yes
| |
| 19:18 | If you only have one client, you could use a rw nfs root instead of ltsp
| |
| 19:18 | <langvann_> Not sure how I do that .. ?
| |
| 19:18 | <alkisg> I don't have a link handy, but I'm sure you can find lots of them on the net
| |
| 19:19 | <langvann_> I guess.
| |
| 19:19 | <alkisg> The hard part is when you need more than one client, because you can't export root rw then
| |
| 19:19 | For just one client it's very easy
| |
| 19:19 | <vagrantc> though because it's so much harder, LTSP was invented, so it might actually be easier to just use LTSP :)
| |
| 19:19 | <alkisg> vagrantc: for fat clients?
| |
| 19:19 | Nah...
| |
| 19:19 | <vagrantc> ah.
| |
| 19:20 | we'll get there...
| |
| 19:20 | <langvann_> hehe
| |
| 19:20 | <alkisg> Sure :) But still, for one client, I believe it's much easier to try rw nfs
| |
| 19:20 | <langvann_> just to proove im not a completely noob, i wrote this in bash: http://langvann.ath.cx
| |
| 19:20 | <alkisg> (I've tried it last summer, it worked fine)
| |
| 19:21 | (with the stock ubuntu kernel)
| |
| 19:21 | (erm, and initramfs)
| |
| 19:21 | <vagrantc> doesn't the initramfs default to ro root?
| |
| 19:22 | <alkisg> ? you can put nfsroot=xxx rw in pxelinux.cfg/default...
| |
| 19:22 | <vagrantc> ah
| |
| 19:22 | <alkisg> I didn't write all the details as it was worthless to me for just 1 client, but I didn't use anything from ltsp
| |
| 19:24 | <langvann_> I will attempt nfsroot
| |
| 19:24 | tomorrow maybe
| |
| 19:24 | But i assumed with the fat client guide, that my computer does all the (computing?), while I only store data and have the / on the server
| |
| 19:25 | <vagrantc> that's the idea
| |
| 19:25 | <alkisg> langvann_: yes it should work fine on ubuntu 10.04 - if you find any problems with the fat client plugin ping me
| |
| 19:26 | <langvann_> sure

| 19:30 | <jammcq> hey all
| |
| 19:31 | <langvann_> alkisg: Thanks alot. you saved my days.

| 19:53 | <alkisg> vagrantc, could you tell me again why the new udhcpc isn't available in debian testing? (http://packages.debian.org/sid/udhcpc) - is it because it's about to freeze?
| |
| 19:54 | (I'm eagerly awaiting to see it in ubuntu maverick because the lucid one isn't working for me and it's forcing me to use ipappend)
| |
| 19:54 | <vagrantc> alkisg: http://release.debian.org/migration/testing.pl?package=busybox
| |
| 19:55 | <alkisg> ah, blocked by freeze, so when squeeze is out, it'll be in testing, right?
| |
| 19:55 | Thanks!
| |
| 19:55 | <vagrantc> sure.
| |
| 19:55 | it might even go in before squeeze releases
| |
| 19:56 | <alkisg> Is squeeze going to be released in the next couple of months?
| |
| 19:56 | <vagrantc> doesn't seem likely
| |
| 19:56 | <alkisg> Ouch
| |
| 19:57 | stgraber: does maverick sync from testing or from sid?
| |
| 19:57 | <vagrantc> i thought they were syncing from testing, but i think you can request to sync something from sid explicitly
| |
| 19:58 | <alkisg> I think that non-LTS releases sync from sid, and LTS releases from testing - but I may be wrong...
| |
| 20:03 | https://wiki.ubuntu.com/DebianImportFreeze => "Prior to this date, new versions of packages will be automatically imported from Debian unstable..."
| |
| 20:06 | Nice it should be in maverick in the next few weeks then. Thanks, good night all...

| 22:31 | <al34n1x> Hi guys, i'm trying to get an LTSP classroom installed and i got some troubles when i tried to use the LDM_ALLOW_USER option on the lts.conf...the option never response...
| |
| 22:31 | I've re run the image and moved the file to the /var/lib/tftboot/ltsp/i386 dir as well
| |
| 22:32 | however the option never response
| |
| 22:32 | i'm running LTSP Server 5.1 on Debian Lenny
| |
| 22:33 | On the other hand i could restrict the DHCP server to match IP with Mac, i didn't have any problem there...the lts.conf file is the problem that i got
