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

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 =)

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

08:58
<Blinny>
So that means they're still being marked as used, though the person has logged out / rebooted?

<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?

Any specific problematic keys ?

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?
10:13puck1 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?
10:29Gadi has joined #ltsp

(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?

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
13:11nesusvet has joined #ltsp
13:13
<thafreak>
nah, no need for optical drives...do the msi winds do pxe?

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

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 ..

15:14
Thanks for the hint

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

<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

sure

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

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
16:12

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>

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
16:29pmatulis 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?
16:44otavio 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
16:49Gadi 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
16:51thafreak 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
16:55tstafford_ has quit IRC
16:56

16:56
?
16:56

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

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...

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
17:41sweetpi 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

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

alkisg: thanks for testing the umounting issues
18:20
<alkisg>

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
