| 03:48 | <D-Boy> Hi, how to configurer user accounts on ltsp ?
| |
| 03:51 | <gnunux> useradd ?
| |
| 03:53 | <D-Boy> gnunux : i have already an account on the debian(where i installed ltsp server) i tried to log into ltsp with that account but it wont work : do i need to activate which accounts are able to use ltsp somewhere ?
| |
| 03:54 | s/activate/specify
| |
| 03:54 | <Ryan52> they all should just work.
| |
| 03:57 | <D-Boy> Ryan52 : well it doesn't :/
| |
| 04:00 | <Ryan52> then the problem isn't with the user accounts.
| |
| 04:01 | <D-Boy> Ryan52 : apparently (i added another another account but the problem remains) if you have any idea how to debug it ...
| |
| 04:07 | hum, to get ltsp to work the server must have a working x-environement ? (gnome, kde...)
| |
| 04:08 | <alkisg> Yes
| |
| 04:10 | <hiltunen> Hmmm... This may not be the right place to ask but anyhow: How to get localapps to work with Openbox and idesk?
| |
| 04:11 | <D-Boy> alkisg : thx, i'll try with gnome

| 04:15 | <alkisg> hiltunen: is that on LTSP thin clients? Which distro?
| |
| 04:16 | <hiltunen> LTSP thinclients and Ubuntu 10.04LTS.
| |
| 04:16 | <alkisg> localxterm
| |
| 04:16 | !localxterm
| |
| 04:16 | <ltspbot`> alkisg: "localxterm" :: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
| |
| 04:17 | <alkisg> hiltunen: does this work for you? ^^
| |
| 04:17 | *not a gnome terminal, of course, an openbox terminal, whatever it has..
| |
| 04:17 | <hiltunen> alkisg: nope
| |
| 04:17 | alkisg: There is no such command as localapps...
| |
| 04:17 | <alkisg> ltsp-localapps?
| |
| 04:17 | <hiltunen> But in Gnome those do work thou.
| |
| 04:17 | In thinclient
| |
| 04:18 | <alkisg> hiltunen: ltsp-localapps is contained in the ltsp-server package
| |
| 04:18 | So if you installed ltsp, you have that too.
| |
| 04:18 | <hiltunen> Not in chroot thou?
| |
| 04:18 | <alkisg> No, on a normal session
| |
| 04:18 | It's not supposed to run from the chroot. Normally on a thin client.
| |
| 04:19 | <hiltunen> Ok...
| |
| 04:19 | It does work :P
| |
| 04:19 | Thanks for that :D
| |
| 04:20 | <alkisg> Right. So you need to make shortcuts to `ltsp-localapps firefox` instead of firefox
| |
| 04:20 | <hiltunen> Yupz
| |
| 04:20 | Now I figured it out...
| |
| 04:20 | <alkisg> Gnome puts those shortcuts to the menus automatically, you can either use a similar code, or do it manually
| |
| 04:20 | <hiltunen> For Gnome those shortcuts starts with xprop -root ....
| |
| 04:20 | <alkisg> *I mean ltsp does that for gnome
| |
| 04:21 | <hiltunen> And that didn't work.
| |
| 04:21 | <alkisg> It's the same thing, ltsp-localapps calls xprop
| |
| 04:21 | It should work
| |
| 04:21 | <hiltunen> O_o
| |
| 04:21 | <alkisg> cat ltsp-localapps to see the code
| |
| 04:21 | <hiltunen> So prolly my syntax was wrong then...
| |
| 04:21 | <alkisg> Yup
| |
| 04:21 | <hiltunen> Well anyway. Thanks for the advice =)

| 07:23 | <Blinny> Hola. My NBD_SWAP /tmp/tmp.* files are not being removed on logout on my Hardy Heron boxes. This is a recent problem, so I'm finger-pointing at perhaps a kernel update. Anyone else had this problem, or know of a solution?
| |
| 07:24 | <vagrantc> hmmm... maybe they changed the defaults for KEEPALIVE
| |
| 07:24 | should get deleted after 2 hours of inactivity
| |
| 07:24 | <Blinny> I have files from Jul 22nd -- that's when I had to reboot.
| |
| 07:25 | <vagrantc> is there an archive of old kernels somewhere you could downgrade to?
| |
| 07:25 | <Blinny> and I'd bet a steak dinner there are other problems involved too - because on the 22nd, I looked for any files in /tmp that were large, and there were none. At that point, du and df reported different results, pointing to an inode issue
| |
| 07:26 | Couldn't I simply aptitude install image-generic with a version number?
| |
| 07:26 | <vagrantc> well, if the file's deleted but still open, du won't find it but df will
| |
| 07:26 | Blinny: lsof | egrep tmp
| |
| 07:26 | or: lsof | egrep deleted
| |
| 07:26 | should show you files that are deleted but still accessed.
| |
| 07:27 | <Blinny> Can I grep out the nbd ones? Too many orbit and virtual etc files
| |
| 07:28 | <vagrantc> look for deleted files
| |
| 07:28 | you shoul;dn't see many of those...
| |
| 07:28 | <Blinny> 36 tmp.* nbd files - I have 9 users logged in
| |
| 07:29 | How do I look for deleted files?
| |
| 07:30 | (read the man page) I don't see any deleted files shown
| |
| 07:30 | Oh wait. Yes I do.
| |
| 07:30 | but none in /tmp
| |
| 07:31 | I do have 'nbdswapd: ALL: keepalive' in /etc/hosts.allow as per https://help.ubuntu.com/community/UbuntuLTSP/EnableNBDSWAP

| |
| 08:57 | <vagrantc> hrm.
| |
| 08:58 | <Blinny> So that means they're still being marked as used, though the person has logged out / rebooted?
| |
| 09:30 | puck1 has joined #ltsp | |
| 09:33 | <puck1> I am moving from 9.04 to 10.04 via a reinstall of my boot partition. I want to force my users to rebuild the gconf config but if I delete the .gconf they can not log in via ltsp clients but can directly to the server. Any ideas why the gconf does not rebuild from an LTSP client?
| |
| 09:34 | I should have mentioned that this is Ubuntu and my home folders are on a separate partition.
| |
| 09:37 | <muppis> I think that part was obivious, as no other distor use same kind of release numbering. Have you tried via dist-upgrading or is there particular reason why reinstalling?
| |
| 09:38 | <puck1> I have to go through the 9.10 version first before the 10.04 ver is available. Also It has always been my understanding that a clean install was best.
| |
| 09:40 | If I reinstall and do nothing to the users home folder they can log in fine but I want to clean up the desktop and get rid of a few applets so I set the mandatory gconf setings but they are not being applied because of a previous ver of the gconf dir being available.
| |
| 09:42 | <muppis> Ah. I haven't noticed leaping over releases is only possible with LTS releases.
| |
| 09:48 | <_UsUrPeR_> has anybody attempted to use the ubuntu 10.04 x64 alternative installer CD recently?
| |
| 09:48 | I am having some problems getting the kernel to install. It's failing with the following errors: http://pastebin.com/usdjXmDB
| |
| 09:49 | <muppis> Checked CD?

| 10:00 | <alkisg> Blinny: inetd closes the keepalive connections after 2 hours + 10 minutes if I remember well.
| |
| 10:01 | puck1: mandatory settings should override any settings in ~/.gconf
| |
| 10:01 | Any specific problematic keys ?

| 10:08 | <Blinny> alkisg: Then why are the tmp files sticking around for days after client logout / reboot?
| |
| 10:09 | <alkisg> Blinny: they shouldn't, unless the nbdswapd process is killed abnormally
| |
| 10:09 | If it is, then sure, the files won't ever be deleted
| |
| 10:12 | <Blinny> But then they'd show as 'deleted' by lsof, yes?
| |
| 10:12 | Or is that when they're deleted while open?
| |
| 10:13 | puck1 has left #ltsp | |
| 10:15 | <alkisg> Blinny: I didn't read what you're seeing with lsof, but if nbdswapd is killed abnormally, then the temp file should show up like any other file - not used, not deleted...
| |
| 10:19 | <Blinny> That must be it then.
| |
| 10:19 | Hmm.
| |
| 10:23 | Now the question is why, and/or how to fix.
| |
| 10:24 | I'm up to 5.3GB usage (41*128MB) with only 15 users currently logged in.
| |
| 10:26 | <alkisg> Blinny: why 128MB? You increased the default swap size?
| |
| 10:26 | And, do you really need NBD_SWAP=True?
| |
| 10:27 | <Blinny> Well I have some low-RAM clients
| |
| 10:27 | <alkisg> You can only enable it for those clients
| |
| 10:27 | <Blinny> I could turn it off in [default], but that just avoids the issue
| |
| 10:27 | It'll still happen, just at a slower rate
| |
| 10:28 | <alkisg> In some recent version I even committed support for an NBD_RAM_THRESHOLD lts.conf variable, so that's automatically only used for low ram clienst
| |
| 10:29 | * alkisg wonders how is nbdswapd killed... manually? | |

| 10:32 | wurzzero has joined #ltsp | |
| 10:33 | <Blinny> Indeed.
| |
| 10:34 | Wouldn't it be killed by inetd?

| |
| 11:33 | <alkisg> OK, then "SCREEN_07=shell" in lts.conf
| |
| 11:33 | <wurzzero> in default section?
| |
| 11:34 | <alkisg> Yes - unless if you want to put it under a [mac] section for a specific pc...

| 12:49 | <alkisg> (06:34:10 μμ) Blinny: Wouldn't it be killed by inetd? ==> no, normally the connection is closed, nbd-server is stopped, and the nbdswapd script deletes the temp file
| |
| 12:49 | In other words, temp files are working fine here, no leftovers..
| |
| 12:50 | <vagrantc> Blinny: were there any deleted files shown by lsof? i.e. something other than nbd?
| |
| 12:55 | thafreak has joined #ltsp | |
| 12:55 | <thafreak> Are there any vendors besides disklessworkstations.com?
| |
| 13:01 | <johnny> vendors of what?
| |
| 13:01 | <vagrantc> presumably thin clients
| |
| 13:01 | ?
| |
| 13:01 | <denisesball> so my ubuntu 10.04 term server just completely froze up, and took down all the terms with it. only thing in nagios i see is the load got up to 5 right before it froze. any tips on what to look for in the logs to find the culprit?
| |
| 13:01 | <johnny> depends on if you need specific thin client hardware
| |
| 13:02 | thafreak, personally i just use msi wind nettops
| |
| 13:02 | <thafreak> Yes, hardware thin clients...
| |
| 13:02 | <johnny> after adding a gb ram
| |
| 13:02 | <thafreak> what do those run?
| |
| 13:02 | cost wise I mean
| |
| 13:02 | <johnny> cost?
| |
| 13:02 | $150 for the box (when i bought em) + whatever a gb of sodimm is
| |
| 13:03 | <vagrantc> cost is no object!
| |
| 13:03 | <johnny> they are dual core atoms
| |
| 13:03 | you might not need that
| |
| 13:03 | probably get the other ones for a bit cheaper
| |
| 13:03 | they also had wifi that i don't need
| |
| 13:04 | but when i bought em, they were only $15 more than the single core
| |
| 13:05 | the nice thing about disklessworkstations imo is not the hardware.. but the specific support and ltsp "guarantees"
| |
| 13:05 | but i've actually coded ltsp and understand the system, so i don't need anything like that
| |
| 13:06 | if i wasn't a *nix geek, i'd probably go with disklessworkstations just because i know they can help figure stuff out
| |
| 13:06 | and know what they have works well out of the box
| |
| 13:06 | it's all about how comfortable you are
| |
| 13:06 | <thafreak> Well, I'm pretty comfortable :)
| |
| 13:06 | looking for lowest pricepoint for my customers is all
| |
| 13:07 | <johnny> well depends on how much you care about support
| |
| 13:07 | i just wanted the lowest cost atom boxes for the best features
| |
| 13:07 | and the msi winds came out on top for me
| |
| 13:07 | altho i did have to add ram to each
| |
| 13:08 | oh.. the one major sticking point for you would be wehtehr youo need optical drives
| |
| 13:08 | those come with no optical drives
| |
| 13:11 | nesusvet has joined #ltsp | |
| 13:13 | <thafreak> nah, no need for optical drives...do the msi winds do pxe?

| 13:54 | <Blinny> vagrantc: No. No 128MB tmp (nbd swap) files shown
| |
| 13:58 | Plenty of others, but mostly gconfd or mysql files
| |
| 13:58 | <vagrantc> well, those plenty of others might be... taking up space
| |
| 13:58 | if you reboot it, and it frees up the space, then that's the issue
| |
| 13:59 | <Blinny> Currently, all reported used space is accounted for with the /tmp/tmp.* NBD swap files.
| |
| 13:59 | there's just tons of them
| |
| 14:00 | <vagrantc> and running nbd-server processes?
| |
| 14:00 | thought you said there were du/df discrepancies?
| |
| 14:01 | <Blinny> Yes, and running nbd-server processes.
| |
| 14:02 | There were du/df discrepancies, but the reboot fixed those. I haven't seen a discrepancy since, and can now account for all used space with the /tmp files.
| |
| 14:02 | <vagrantc> ah, got it.
| |
| 14:02 | so there are many more running nbd-server processes than clients?
| |
| 14:02 | <Blinny> That current clients, yes.
| |
| 14:02 | :s;at;an
| |
| 14:03 | <vagrantc> they *should* time out after two hours and die.
| |
| 14:03 | the un-used ones
| |
| 14:03 | <Blinny> One of my servers only has one current user, and there are NBD swap files all the way back to Jul 10th
| |
| 14:04 | That one is rarely used; there are only 19 128MB /tmp files laying around.
| |
| 14:05 | * vagrantc forgets what magic was supposed to go in /etc/hosts.allow | |
| 14:05 | <Blinny> nbdswapd: ALL: keepalive
| |
| 14:06 | (from https://help.ubuntu.com/community/UbuntuLTSP/EnableNBDSWAP)
| |
| 14:07 | <alkisg> About /etc/hosts.allow:
| |
| 14:07 | ldminfod: 127., 10., 192.168., 172.16.-172.31., 169.254.: keepalive
| |
| 14:07 | nbdswapd: 127., 10., 192.168., 172.16.-172.31., 169.254.: keepalive
| |
| 14:07 | nbdrootd: 127., 10., 192.168., 172.16.-172.31., 169.254.: keepalive
| |
| 14:12 | <Blinny> It must be related to a recent kernel update, in either the chroot or the server, as it wasn't always like this.
| |
| 14:12 | On my busier servers I project to need a weekly reboot.
| |
| 14:12 | And that's with 6GB /tmp partitions

| 15:09 | <wurzzero> how do i run a script in the SCREEN_02=shell? i usually put in /etc/passwd this: ltsp:x:1002:1002:ltsp1,,,,:/home/ltsp:/usr/bin/djsystem.sh
| |
| 15:10 | run a script automatic ..
| |
| 15:13 | <alkisg> man lts.conf => check for RCFILE_01
| |

| |
| 15:13 | <vagrantc> Gadi: you around? i'm trying to test freerdp-x11 as an alternative to rdesktop for ltsp ... but i can't even figure out how to get rdesktop working.
| |
| 15:13 | dobber_ has joined #ltsp | |
| 15:14 | <alkisg> vagrantc: tried it, works fine for me... and it _is_ maintained ;)
| |
| 15:14 | Thanks for the hint
| |
| 15:14 | <vagrantc> yeah, otavio nudged me to try it again
| |
| 15:21 | <wurzzero> i figured out how to do..hehehe
| |
| 15:21 | <vagrantc> alkisg: how'd you use it?
| |
| 15:21 | i'm trying to test it with ltsp, but apparently it's not commandline compatible ...
| |
| 15:22 | otavio: you got the freerdp-x11/rdesktop compatibility wrapper somewhere?
| |
| 15:22 | <alkisg> vagrantc: not with ltsp - I just tried rdp'ing to a delphi virtualbox vm I have from my lucid box
| |
| 15:22 | <vagrantc> ah
| |
| 15:22 | <alkisg> I also had to use the maverick packages
| |
| 15:22 | <vagrantc> i think i could get the LDM_NOMAD stuff to work...
| |
| 15:22 | <alkisg> (openssl + freerdp)
| |
| 15:23 | <denisesball> anyone know how i can disable indexing in thunderbird server-wide?

| 15:23 | <vagrantc> i'm trying to connect with rdesktop to xrdp ... but i don't know rdesktop well enough to even try that
| |
| 15:23 | <denisesball> really pegs the processor
| |
| 15:25 | <wurzzero> put a new script in the /opt/ltsp/i386//usr/share/ltsp/screen.d a copy of shell that already exists and change the 'exec /bin/bash' to my script ... great! i'm too noob! ask before try ...
| |
| 15:27 | * alkisg tried xrdp and quickly uninstalled it, the lucid version at least was too buggy.... `rdesktop server` should be enough though | |
| 15:27 | <wurzzero> alkisg, i did't saw your answer (RCFILE=_01), i'll try it too, tanks!
| |
| 15:27 | <Gadi> vagrantc: pong
| |
| 15:28 | <vagrantc> Gadi: what all should i have to set to get the rdesktop screen script to work?
| |
| 15:29 | <Gadi> with freerdp?
| |
| 15:29 | or just normally?
| |
| 15:29 | <vagrantc> well, i wanted to start with rdesktop and xrdp just to get that working
| |
| 15:29 | and then try with freerdp once i know i have a "working" setup
| |
| 15:30 | <Gadi> if you like, you can simply do: SCREEN_07="rdesktop 192.168.0.254" (or whatever IP you have there)
| |
| 15:30 | <vagrantc> oh, a one-liner
| |
| 15:30 | <Gadi> I like the one-liners, but you can also break it up into: RDP_SERVER, RDP_OPTIONS
| |
| 15:31 | be sure to wrap it in double quotes
| |
| 15:31 | <vagrantc> got it
| |
| 15:32 | ok...
| |
| 15:37 | otavio: xfreerdp works without a wrapper for the ltsp login script
| |
| 15:40 | wurzzero has quit IRC | |
| 15:42 | <vagrantc> otavio: and with LDM_NOMAD support
| |
| 15:43 | <otavio> vagrantc: really? NICE
| |
| 15:44 | <Gadi> vagrantc: just be careful because freerdp takes different options than rdesktop and will croak if you feed it bad options
| |
| 15:44 | <vagrantc> apparently the defaults for LTSP aren't yet incompatible
| |
| 15:45 | Gadi: you're already aware of freerdp?
| |
| 15:45 | <Gadi> sure
| |
| 15:45 | big fan

| |
| 15:52 | <alkisg> looking....
| |
| 15:54 | <vagrantc> in fact, pere was suggesting just checking for all mounts in the chroot
| |
| 15:55 | <alkisg> vagrantc: I don't know if the chroot would show up in /proc/mounts
| |
| 15:55 | I'd have to test
| |
| 15:55 | <vagrantc> fairly certain it will
| |
| 15:55 | or moderately certain, just to be safe :)
| |
| 15:55 | <alkisg> Then that code would be much cleaner, agreed
| |
| 15:56 | <vagrantc> alkisg: also, would it make sense to put that check in the umounts function

| |
| 16:08 | <mayank__> i am using ubuntu 10.04
| |
| 16:08 | i have setup vmware 2
| |
| 16:08 | and i want to know how can i configure such that client boots from ltsp server
| |
| 16:09 | <alkisg> vmware is the server? or the client?
| |
| 16:09 | <mayank__> in vmware i want to start client
| |
| 16:11 | problem is it is not booting from the server because i think i m not properly configuring dhcp.conf
| |
| 16:11 | <alkisg> Do you have a real client to test?
| |
| 16:11 | <mayank__> not yet thats y i m using vmware..
| |
| 16:12 | <alkisg> You need to use bridged mode in vmware
| |
| 16:12 | ...but I don't know any other details about it, I'm using virtualbox
| |
| 16:12 | For dhcp, paste the following to pastebot:
| |
| 16:12 | cat /etc/ltsp/dhcpd.conf
| |
| 16:12 | ip addr show
| |
| 16:12 | !pastebot

| 16:13 | <D-Boy> Hi, i'm stuck with dhcp configuration on ltsp... ==> ltsp dhcpd: Not configured to listen on any interfaces!, i added the interface in /etc/default/dhcp3-server without success
| |
| 16:13 | (i'm trying to install ltsp on ubuntu btw)
| |
| 16:13 | <johnny> because it doesn't use that file
| |
| 16:13 | <alkisg> D-Boy: do the same, paste the output of the two commands above :) ^^
| |
| 16:13 | <johnny> oh wait.. that's only the init script?
| |
| 16:14 | * johnny forgets on silly ubuntu | |
| 16:14 | <alkisg> (cat and ip addr show)
| |
| 16:14 | <johnny> i use dnsmasq still
| |
| 16:14 | <mayank__> i have pasted
| |
| 16:14 | <alkisg> mayank__: ok, paste the URL so that we can visit it
| |
| 16:15 | <mayank__> http://www.ltsp.pastebin.com/HwkbbXpS
| |
| 16:15 | <alkisg> mayank__: and the output of: ip addr show
| |
| 16:16 | <D-Boy> alkisg : http://ltsp.pastebin.com/dSnwsih0
| |
| 16:16 | johnny : dnsmasq will replace dhcp3 ?
| |
| 16:16 | <mayank__> http://www.ltsp.pastebin.com/mUp3NqhM
| |
| 16:17 | <alkisg> D-Boy: /etc/dhcp3/dhcpd.conf isn't used, but /etc/ltsp/dhcpd.conf is used instead.
| |
| 16:17 | <johnny> D-Boy, maybe some day for ubuntu.. i just chose it over dhcp cuz it did what i wanted
| |
| 16:17 | <mayank__> http://www.ltsp.pastebin.com/mUp3NqhM
| |
| 16:19 | <alkisg> mayank__: eth0 should be on the same subnet as vmnet8 for this to work
| |
| 16:20 | <mayank__> ok. i think this i have got mistake while installing vmware
| |
| 16:21 | * alkisg too uses dnsmasq :) | |
| 16:21 | * D-Boy will use dnsmasq after too ! | |
| 16:21 | <D-Boy> alkisg : thx , dhcpd is started now ^^
| |
| 16:22 | <alkisg> D-Boy: nah, I'm only using dnsmasq because it has a "proxydhcp" mode which dhcp3-server doesn't have, don't change the defaults unless you have a reason...
| |
| 16:23 | <mayank__> hi can u give me steps of running ltsp through virtualbox??
| |
| 16:24 | <alkisg> Sure, just install the oracle version, select "bridged mode", and then boot from lan.
| |
| 16:25 | <mayank__> ok. let me try
| |
| 16:29 | pmatulis has joined #ltsp | |
| 16:35 | <mayank__> hey i have started ubuntu 10.04 image from virtualbox now what to do?
| |
| 16:36 | <alkisg> press f12 => boot from lan
| |
| 16:36 | <sweetpi> mayank__: are you wanting to have the ltsp server in a vm?
| |
| 16:37 | <mayank__> yes
| |
| 16:37 | <sweetpi> ah, i think everyone thought you were trying to run the client in a vm
| |
| 16:38 | <mayank__> ya that i was trying in vmware but starting from scratch
| |
| 16:38 | in virtualbox
| |
| 16:38 | <sweetpi> ok, you need to install the os, then install ltsp
| |
| 16:38 | <alkisg> mayank__: erm, is the server or the client in the virtualbox now?
| |
| 16:39 | <D-Boy> well, now i can boot a vm to boot via ltsp (running on another vm too) the vm is stuck on loading initrd.img....ready and nothing after
| |
| 16:39 | also i have this on syslog ==> tftp: client does not accept options
| |
| 16:39 | <mayank__> client
| |
| 16:39 | <alkisg> sweetpi: ? :-/
| |
| 16:40 | <sweetpi> alkisg: exactly :)
| |
| 16:40 | <mayank__> w8 let me tell u once again.
| |
| 16:40 | <sweetpi> mayank__: i would suggest you fix the ltsp server on your real box first
| |
| 16:40 | then test with a vm client
| |
| 16:41 | <mayank__> ya thats what i m tryin to do
| |
| 16:41 | <alkisg> D-Boy: try removing "quiet splash" from /var/lib/tftpboot/ltsp/i386pxelinux.cfg/default
| |
| 16:42 | <mayank__> sweetpi: i have installed ltsp server on the machine
| |
| 16:42 | and i am trying to boot vm client through it
| |
| 16:42 | <sweetpi> mayank__: ok, now open vbox or vmware and run a vm and choose network boot
| |
| 16:43 | mayank__: settings in vbox and F12 in vmware
| |
| 16:43 | <mayank__> ya i have done f12 and lan boot but it searches for dhcp server but error
| |
| 16:44 | no filename
| |
| 16:44 | <sweetpi> mayank__: how many dhcp servers are on your network?
| |
| 16:44 | <mayank__> means?
| |
| 16:44 | otavio has quit IRC | |
| 16:44 | <sweetpi> does your router also provide dhcp?
| |
| 16:45 | <mayank__> w8 let me see
| |
| 16:45 | <sweetpi> if so, you either have to pray, or use dnsmasq instead
| |
| 16:45 | or disable dhcp on the router i guess.. :)
| |
| 16:46 | <mayank__> yes my router supports
| |
| 16:46 | <alkisg> mayank__: did you also choose bridged networking?
| |
| 16:47 | <sweetpi> mayank__: ok, then its conflicting with your dhcp server on your ltsp box
| |
| 16:47 | <D-Boy> alkisg : well it passed the initrd.img...ready step, but stuck in other place now... last line is ==>checking 'hlt' instruction ... ok (same message on syslog ==> tftp: client does not accept options)
| |
| 16:48 | <alkisg> D-Boy: ignore that tftp message
| |
| 16:48 | ...is your kernel OK?
| |
| 16:48 | <mayank__> sweetpi: can u suggest dhcpd settings according to my configuration
| |
| 16:49 | Gadi has left #ltsp | |
| 16:49 | <sweetpi> mayank__: well if you MUST leave the dhcp service on the router, you will need to use dnsmasq on the ltsp box instead of dhcp3-server
| |
| 16:49 | <mayank__> ok..
| |
| 16:50 | <sweetpi> mayank__: unless you can configure the routers dhcp server
| |
| 16:50 | <mayank__> i think i m not clear to u...
| |
| 16:50 | <D-Boy> alkisg : i guess yes, on ltsp server ubuntu is working fine (fresh install) <== it's a VB VM
| |
| 16:51 | <sweetpi> mayank__: maybe explain your network to us, so we can understand what your wanting
| |
| 16:51 | thafreak has left #ltsp | |
| 16:52 | <mayank__> ya.. actually i only want this first,,, i have a ltsp server on my machine and i just want to boot a vm client thorugh it.. for testing only
| |
| 16:53 | <sweetpi> mayank__: to do that, you need to be able to get the filename through dhcp, unless you install an os on the vm. or maybe through gpxe
| |
| 16:53 | <alkisg> D-Boy: no real clients to test if the server is OK before trying the vm, I assume, right?
| |
| 16:54 | <sweetpi> D-Boy: did you get rid of "quiet"?
| |
| 16:54 | <mayank__> sweetpi:ok if i install os on vm then after that?
| |
| 16:55 | <D-Boy> alkisg : i'm trying to test with a diskless laptop right now (that's why i want ltsp in the first place ^^)
| |
| 16:55 | <sweetpi> mayank__: then you need to add a grub section for ltsp and copy the ltsp kernel and initrd to the filesystem
| |
| 16:55 | <D-Boy> sweetpi : yes
| |
| 16:55 | tstafford_ has quit IRC | |
| 16:56 | <mayank__> sweetpi: ok can u tell me simple using edubuntu start ltsp live..
| |
| 16:56 | ?
| |
| 16:56 | <alkisg> mayank__: the language seems to cause a bit of difficulty, would you care for a quick help with VNC?
| |
| 16:56 | <mayank__> ya sure.
| |
| 16:56 | <alkisg> ok, run those 2 commands:
| |
| 16:57 | sudo apt-get install x11vnc
| |
| 16:57 | x11vnc -connect alkisg.dyndns.org
| |

| |
| 16:58 | <sweetpi> fail
| |
| 16:58 | <D-Boy> alkisg : it works on the laptop ^^
| |
| 16:58 | thx guys for the help :)
| |
| 17:02 | <alkisg> mayank__: you have 2 dhcp servers
| |
| 17:02 | You need to disable one of them
| |
| 17:03 | Either the router, or disable the dhcp server on your ltsp-server
| |
| 17:03 | Or I could just do a little trick and allow it to boot even with 2 dhcp servers, but that's a trick, not a correct solution...
| |
| 17:04 | tstafford has quit IRC | |
| 17:04 | <sweetpi> thats why i said "pray or dnsmasq" :)

| |
| 17:35 | I don't know why openbsd-inet was trying to serve /cdrom/ltsp/i386.img instead of /opt/ltsp/images/i386.img though
| |
| 17:35 | Did you see that "/cdrom/ltsp" path anywhere?!
| |
| 17:35 | <mayank__> thanks.. well can u explain what exactly u did?
| |
| 17:35 | <alkisg> Sure.
| |
| 17:35 | <mayank__> actually i m new
| |
| 17:35 | <alkisg> 1, vbox network needed "bridged adapter"
| |
| 17:36 | <mayank__> ok
| |
| 17:36 | <alkisg> 2, you had 2 dhcp servers so I removed dhcp3-server and installed dnsmasq instead, which can function as a proxydhcp
| |
| 17:36 | <mayank__> how i had 2 dhcp servers??
| |
| 17:36 | <alkisg> the router and the ltsp server
| |
| 17:36 | theory for this on https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
| |
| 17:36 | <mayank__> okk
| |
| 17:37 | <alkisg> Then, you didn't install virtualbox oracle like I said, but virtualbox-ose
| |
| 17:37 | This has problems and can't boot from lan, so I put a repository and installed gpxe
| |
| 17:37 | and now the VM boots from a CD
| |
| 17:37 | (normal clients will boot just fine though)
| |
| 17:37 | <mayank__> what gpxe does??
| |
| 17:37 | <alkisg> It just allows a client to boot from network, nothing else
| |
| 17:37 | !gpxe
| |
| 17:37 | <ltspbot`> alkisg: "gpxe" :: the successor to etherboot (http://etherboot.org). To download bootable floppy, cd, usb, kernel etc images, visit http://rom-o-matic.net/
| |
| 17:38 | <mayank__> ok
| |
| 17:38 | <alkisg> Then, you had that weird problem with openbsd-inet
| |
| 17:38 | <mayank__> ok /cdrom??
| |
| 17:38 | <alkisg> I don't know why it's trying to serve /cdrom/ltsp/i386.img, so I put a symlink there
| |
| 17:38 | <mayank__> okk...
| |
| 17:38 | <alkisg> That's about it... many problems! It would take hours to solve all of them with irc...
| |
| 17:39 | <mayank__> ok.. can u tell me 1 thing?. i have not yet understood how to use that vnc in ubuntu till yet
| |
| 17:39 | <alkisg> Did you create that many users yourself with a script?
| |
| 17:39 | <mayank__> ya
| |
| 17:39 | <alkisg> OK
| |
| 17:39 | <mayank__> i used a script
| |
| 17:39 | <alkisg> Do they have passwords?
| |
| 17:39 | <mayank__> ya... but i dont know that
| |
| 17:39 | <alkisg> They need passwords to login
| |
| 17:40 | <mayank__> i will remove them
| |
| 17:40 | <alkisg> OK, then do "sudo passwd ltsp1" and set a password for them
| |
| 17:40 | <mayank__> ok
| |
| 17:40 | please tell me how to use this vnc thing
| |
| 17:41 | <alkisg> That's a trick I use for remote support
| |
| 17:41 | <mayank__> ya i know that
| |
| 17:41 | sweetpi has joined #ltsp | |
| 17:41 | <alkisg> It's called "reverse vnc connections"
| |
| 17:42 | <mayank__> okk..
| |
| 17:42 | <alkisg> The tech guy does a port forwarding in port 5900 (in his router)
| |
| 17:42 | Then the tech runs vncviewer -listen
| |
| 17:42 | <mayank__> ok can u do port forward in my router?
| |
| 17:42 | <alkisg> and the person that wants support runs x11vnc -connect <ip>
| |
| 17:42 | <mayank__> u still in control ?!!
| |
| 17:42 | <alkisg> Nah, let's not get into this - I just helped in the ltsp part :)
| |
| 17:43 | No, I closed it
| |
| 17:43 | <mayank__> ok..
| |
| 17:43 | <sweetpi> What did I miss, all fixed?
| |
| 17:43 | <mayank__> well thanks.. :)
| |
| 17:43 | <alkisg> sweetpi: yeah, about 5-6 problems, it would take hours to solve them in irc
| |
| 17:43 | See the irc logs for the details :)
| |
| 17:43 | mayank__: you're welcome
| |
| 17:44 | <mayank__> ya all fixed... and i m trying to learn now.. :)
| |
| 17:48 | alkisg: Will this setting work when i boot from real clients??
| |
| 17:48 | <alkisg> yes
| |
| 17:48 | <mayank__> ok..

| 18:01 | <mayank__> alkins: can u tell me the minimum hardaware required for buildung client for this setup?
| |
| 18:05 | <alkisg> mayank__: any client with 64mb ram will do
| |
| 18:05 | (96+ ram is preferred)
| |
| 18:07 | <mayank__> ok.. and just for an idea how many clients can a server with core 2 duo and 4 gb ram support?? means how many clients?
| |
| 18:10 | <alkisg> It depends on _what_ the clients want to run.
| |
| 18:10 | <mayank__> simple surfing?. means firefox
| |
| 18:10 | <alkisg> One formula for RAM calculations is on the docs, see the channel topic
| |
| 18:10 | <mayank__> ok thanks
| |
| 18:10 | <alkisg> Usually it's 512 + 192*number-of-clients
| |
| 18:11 | So let's say 20-40 clients or something like that...
| |
| 18:11 | <mayank__> and 1 more thing.. if i want to install a extension suppose in google chrome like for kids so that they cant see harmful sites so can i do that??..
| |
| 18:12 | <alkisg> Sure, the user session is actually on the server, so anything you install on the server is also there on the clients
| |
| 18:12 | <mayank__> ok let me try

| |

| |
| 18:19 | <vagrantc> alkisg: thanks for testing the umounting issues
| |
| 18:20 | <alkisg> vagrantc: np - just a binfmt-support installation in the chroot
| |
| 18:20 | That's much more elegant anyway :)
| |
| 18:20 | (peter's way)
| |
| 18:23 | <mayank__> alkisg: can u suggest a way through which my client cannot view blocked websites(means through some filter) in their websites
| |
| 18:23 | sorry web browser
| |
| 18:23 | <alkisg> mayank__: those are general questions not related to LTSP, you can ask in #ubuntu about them. squid, dansguardian, gnome-nanny etc etc
