<alkisg>
So... I'm about to implement the shared folders idea into sch-scripts. And I'm wondering if I should split it into a clean separate package instead, or just focus on trying to get sch-scripts into debian some day.
00:05
I'm afraid thought that sch-scripts will have a hard time getting into debian, as their current policy is "sed through any configuration files we need as long as it makes life easier for schools" :-/
00:05
E.g. "increase max concurrent unauthenticated ssh connections to 20", or "run lightdm-set-defaults to set the default session to gnome-session-fallback".
00:05
...question... if that configuration file editing wasn't done in postinst, but was provided by e.g. some menus, so that it was user-driven, would that be OK, as far as the debian policy is concerned?
00:06
<vagrantc>
alkisg: technically compliant, yes.
00:07
alkisg: at that point, it's an admin decision ... it does, however, still interfere with upgrades and such ...
00:08
till next time!

<rkwesk>
is it possible to use the mbr of hard drive on a client that has no bios with pxe so that a dual boot menu is presented giving the user two options: either to boot local windows server 2000 or go on to tftp to receive linux from the server?
09:37
<muppis>
Yes.
09:38
!win32-loader
09:38
<ltsp_>
muppis: win32-loader: win32-loader.exe can be used to add a "PXE - Network boot" option to the Windows boot manager. It's developed for Debian and it uses gPXE/iPXE for the network booting. You can download a binary from http://ftp.debian.org/debian/tools/win32-loader/unstable/ (if someone can write a wiki page about it it'd be nice :))
09:38
<rkwesk>
how is this done?
09:38
<muppis>
rkwesk, use that ^
09:38
<rkwesk>
aha so ipxe is not the way to go
09:39LoveStorm has joined IRC (LoveStorm!Storm@gateway/shell/trekweb.org/x-shestqnkuuqkoeiq)
09:39
<muppis>
It uses iPXE, but it's loaded via grub.
09:40
<rkwesk>
so grub (or grub2) is chainloading ipxe?
09:40
<muppis>
Yes.
09:41
<rkwesk>
thank you. certainly if i manage it i will contribute a walk through on the wiki

10:20
In reshly build fat client alt-tab doesn'y work.
10:22
<alkisg>
...that makes no sense though, fat clients just use a network disk, they should behave the same as normal installations. Unless it's also broken on desktop installations too.
10:23
<muppis>
Let's see.
10:32
<alkisg>
Also try with a new users so that you make sure it has no custom settings anywhere
10:42

CAn't get VirtualBox booting from lan..
10:44
Ah, didn't got expansion pack installed.
10:46
Damn, I love virtualization :)
11:09
Do I look stupid? Assining only 512 MB of RAM for fat.. No wonder why it's slow.

<Guest88250>
Gentlemen my intention is to use the advice from this gathering to create a new ltsp server to handle the teaching of ICT.
12:48
I must profess to being relaay disappointed at the Ubuntu documentation. It tells me everything apart from what I need to know. I have gained the impression thta some of the recommendations
12:50
are not for people like me who have an actual multi user requirement. I have a room which is to have 30 users in it. I understand all the limitations of the hardware but basically the specification is simple .
12:53
30 clients with access to the Internet. The client machines are Dell Dimension 2400 and Dell Optiplex GX 280. I have a server with LTSP 10.04 on it already. This works on the LTSP client side but
12:56
I have not got the Internet Access via the second network card. Nor can I find information which refers to an installation created using the 10.04 Alternative Disk and how to troubleshoot problems with the Internet side of things
13:00
The connection to the router is via a different switch currently, and has an IP of 192.168.1.100.
13:00
So if I start again which way should I set this up and using what
13:03adrianorg_ has joined IRC (adrianorg_!~adrianorg@177.18.48.65)
13:04
<Guest88250>
How do I set up the Internet side of things to what I want based on what currently exists? I can do a new install in situ, but do I let it try and do it itsel via the Alternate Disc. Will it find the Internet router ?
13:06
Anybodies thoughts welcome.

<Hyperbyte>
Guest88250, you know it's supposed to be -weekend-, right? :P
13:33
<Guest88250>
Would you suggest I wait for a weekday ?
13:34* alkisg didn't understand what Guest88250's problem is... clients cannot access the internet?
13:36
<Guest88250>
Yes and I do not know how to fix it because I do not understand how the alternate disk method of setting things up is done
13:36
<Hyperbyte>
Guest88250, you have better luck then, in general... but I'd start by getting to specific questions.
13:37
Or better yet, just trying out LTSP, to test it, and then see if you have questions.
13:38
How do you set up internet to what you want? Well, figure out what you want and then configure it?
13:38
Will Ubuntu find an internet router? Possibly, if the router is configured to hand out DHCP and the server is configured to accept it. Else you'll want to set an IP address manually...
13:39
Either way, Ubuntu can work with routers, if that's your question...
13:39
<Guest88250>
Clients are able to log in and that side works. I have no Internet access via the server or from the clients. I have looked to try and find what I need to check but I can find very little.
13:42
<alkisg>
Describe your network setup in details. How many switches, NICs on the server, where are the clients connected, where is the router connected etc.
13:43
This is the typical setup: http://wiki.ubuntu-gr.org/LTSP/%CE%92%CE%B1%CF%83%CE%B9%CE%BA%CE%AD%CF%82%CE%93%CE%BD%CF%8E%CF%83%CE%B5%CE%B9%CF%82%CE%A0%CF%81%CE%BF%CE%B5%CF%84%CE%BF%CE%B9%CE%BC%CE%B1%CF%83%CE%AF%CE%B1?action=AttachFile&do=get&target=ltsp_inet2.png
13:45
<Guest88250>
Yes it is the standard two nic set up. I set up the installation at home and it was exactly like this.
13:46
<alkisg>
So if you work on the server now, it has internet?
13:46
<Guest88250>
I have had to move the installation into the schoolroom. However the system is exactly the same but the router ip will be different and also the router is on the other side of a switch
13:47
<alkisg>
In the picture, the router is not connected to the switch. What do you mean "its other side"?
13:47
Please be more accurate.
13:47
<Guest88250>
It had an internet connection at home, but none in the schoolroom. I am not at school at the moment.
13:48
<alkisg>
How many switches do you have at school?
13:49
(in the specific lab where you're trying to install)
13:49
One?
13:49
<Guest88250>
When set up at home there was an ethernet cable directly to the router. At school there is an ethernet cable to a switch. The router is also connected to the switch.
13:50
<alkisg>
Where is the second ethernet card of the server connected? (to the school)
13:51
<Guest88250>
One ethernet card goes to a switch and all of the clients are connected to that switch. The other ethernet card is connected to ANOTHER switch. The router is also connected to this other switch. switch
13:52
<alkisg>
Nice. So, forget about the clients for a minute. Did the server have internet? I'm guessing "no", so you didn't set up your network connection properly. Right?
13:53
It's possible that you put the cables in the wrong order, i.e. if you swap the 2 network cables in the 2 NICs of the server, it might work.
13:54
As one is configured to get a dynamic IP (DHCP), and the other one is static, for the LTSP clients.
13:54
<Guest88250>
I feel that it did at home, but not in the school arrangement
13:54
<alkisg>
All those are described in the ltsp docs, which you can find at the topic of this irc channel, or at this page: https://help.ubuntu.com/community/UbuntuLTSP/
13:55
<Guest88250>
I think I have the connections correct since the clkients can log in .
13:57
<alkisg>
Did you set up a static IP at home, for the internet-facing NIC?
13:57
If so, you need to change it at school to match the network settings there.
13:58
<Guest88250>
alkisg - it may be easier to re install all of this. My final question is if I use the Alternate disc with the server and the clients and the router connected as shown is this the best way to do this type of install?
13:58
<alkisg>
So if your cabling is correct, the problem isn't LTSP related, you just need to setup an internet connection, you can find hundreds of pages on google for that.
13:58
Reinstall instead of setting up an internet connection? I don't think it's worth it...
14:01
<Guest88250>
OK I will try. My thoughts have been that because the Internet is being shared there must be some form of bridging going on and I did not therefore see this as something that was straightforward. From what you are saying if I set the Iinterface which is being used for the INternet to suit the ip adddress of the router this is all that is needed.
14:02
<alkisg>
Right
14:02
The thin client session is on the server, so whatever the server can access, the client can also, without requiring bridging or NATting etc
14:02
After logging in on the client you ARE on the server
14:03
<Guest88250>
Thanks Alkisg - I shall go into work tomorrow and see what I can do . I thank you for all your help and shall leave you in peace.
14:03
<alkisg>
You're welcome, good luck

Odd. When I create a new user and log it in from fat, everything works just like it should. When I recreate a homedir for my own account, nothing works.
