Hi Guys I'm setting up Nat and need to setup a default nameserver for the LAN. But have none at this time. Could I setup the server ip as found in cat /etc/network/interfaces as default DNS and would that jeoprodise my internet DNS?
07:58vagrantc_ has left IRC (vagrantc_!~vagrant@conference/debconf/x-csllxbrdixbxgycr, Ping timeout: 260 seconds)
07:58
<alkisg>
Barco: the DNS can be outside of the local LAN
07:58
So you can use your existing DNS server, wherever that is, even if it is behind NAT
07:59vagrantc has joined IRC (vagrantc!~vagrant@conference/debconf/x-ocjloqjquhlfhesj)
08:01
<Barco>
Thanks! I'm looking at https://help.ubuntu.com/community/UbuntuLTSP/StaticIPsWithDHCP
08:01
<alkisg>
This doesn't have anything to do with NAT though
08:01
(nor with DNS :))
08:02
<Barco>
;) LOL
08:03
I've gone through the steps to setup NAT but am trying to get Static Ip's assigned to clients when they boot though gpxe
08:03
<alkisg>
Is the LTSP server your DHCP server as well?
08:03
(for the ltsp clients)
08:04
<Barco>
Yes, they have been getting their IPs from the LTSP server through DHCP as far as I could see
08:05
<alkisg>
OK then just add their mac addresses in /etc/ltsp/dhcpd.conf as that wiki page says
08:05
Don't do the pxelinux sections, they don't apply to you
08:06
<Barco>
This is the Dhcp.conf section http://pastebin.com/EugsbT8h
08:07
<alkisg>
Yes, you need to add to it entries like: host client201 { hardware ethernet 08:00:27:89:70:01; fixed-address 192.168.0.201; }
08:07
<Barco>
aha, I see ISO doing PXE parts.
08:11
I think someting went wrong with my nat config, cant's seem to reach my webserver on http://localhost or the internet for that matter I'm just going to back up a bit and recheck that. BTW how's the weather over in your country?
08:14
<alkisg>
NAT doesn't interfere with localhost.
08:14
Localhost == the same pc. So no natting there.
08:14
Weather's fine, all sunny
08:14
<Barco>
Worked before I started with the Nat setup, it's why I'm looking here.
08:18
by here I mean looking at NAT
08:19
<alkisg>
That ubuntultsp wiki nat page needs rewritting
08:21
<Barco>
A lot of the Wiki pages do, most seem to be based on Ubuntu 9
08:21
<alkisg>
Unfortunately only a couple of people have been updating the wiki.
08:22
Even people getting help here don't update the wiki after they've solved their problems
08:22* muppis shames itself. Likes to help in rewrites, but doesn't have time.
08:23
<Barco>
I'll be one of them when I know more. But right now me writing about Ubuntu will be dangerous ;)
08:23
<alkisg>
Hehe
08:23
<Barco>
I get the message unable to connect to server at localhost.
08:23
I'm thinking the local terminal does not know how to connect to the internal server via http?
08:24
<alkisg>
I think you're a bit comfused
08:24
Localhost means "the pc I'm sitting on"
08:24
So when you try http://localhost from a thin client, you're asking for the web server ON THE THIN CLIENT
08:24
Which you don't have
08:24
<Barco>
I see what you mean and therein lies the solution!
08:24
<alkisg>
If you want to access the server web server, try: http://server
08:31
<Barco>
Hmm, can't seem to reach it at http://LabServer - going to try to ping and then connect using the ip adress.
08:32
I see you literally meant http://server
08:32
<alkisg>
:)
08:33
<Barco>
could I literally install a web app at http://server iso localhost or is this simply a redirect?
08:35
I had my internal website installed at locahost since each ltsp client was running firefox on the server anyway. But will have to move it.
08:37
Since http://server/directory now redirects me http://localhost/directory. Change is good and mostly painfull (sigh)
08:37
<alkisg>
The ltsp clients automatically get a DNS entry for "server" in /etc/hosts
08:37cyberorg has joined IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg)
08:38
<alkisg>
One easy way to make it work for firefox working on the server too, is to add a "server" entry in the server /etc/hosts too
08:42cyberorg has left IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg, Read error: Connection reset by peer)
08:47
<Barco>
Thanks, alas it seems I will have to reinstall the website grr. I get to the site but then get a redirect message saying this site can only be accessed on localhost. then blam host not found ;) But I think your sugestion will help me to access the site on the server once it has been migrated.
08:50
A last question, I have two terminals that start with refreshrates and resolution way beyond what even a 19' monitor can display.
08:52
I don't understand how the values of X_HORZSYNC X_VERTREFRESH relate to actual refresh rate and horisontal sync - I'm guessing resolution
08:52
<alkisg>
Try putting this in lts.conf: XRANDR_MODE_0=1024x768
08:53
Don't use X_HORZSYNC/X_VERTREFRESH if you don't have to
08:55
<Barco>
aha, that's what I'm looking for. I'll try that first. Thanks a million!
09:00
<Hyperbyte>
Hey Barco! How's your project going?
09:02
<Barco>
A bit hectic, I've been setting up an inhouse pilot with Alkisg's help. Have a dual core server running but still hunting for thinner clients LOL
09:03
I'm in a expansion fase in my business and still wondering to myself why all the most amazing ideas come at the most inproper times
09:04
So am speaking to friends in between the hecticness. Chasing a hard deadline for 18h00 tonight with about 2days work left. Grr
09:06
Hyperbyte - I'll chat again soon and keep you guys informed how it's going with the project.

19:56
<vmassuchetto>
After boot the clients keep sending lots of DHCPREQUEST. Is that normal?
19:56
<alkisg>
It is because you have a very low lease time, 600 secs
19:56
Increase your lease time, there's no point in it being so low
19:57
<vmassuchetto>
alkisg, What's a good lease?
19:57
<alkisg>
The default
19:57
So just don't mess with it :)
19:59
<vmassuchetto>
alkisg, The curious is that other non-LTSP clients dont send anything.
19:59
<alkisg>
There's also the problem with udhcp not updating its lease properly
20:00
The one I told you to file a bug about, which you said you have to time for it
20:01
<vmassuchetto>
alkisg, The requests are because of that?
20:01
<alkisg>
Since udhcp fails to update its lease, it's possible that it does more frequent requests than the 600 secs
20:01
It's looking at the wrong path for the script to exec
20:03
<_UsUrPeR__>
a quick question: Is it possible to boot LTSP to X windows? I am trying to put together a LTSP client image that starts X with no window manager, and runs chrome
20:03
<Hyperbyte>
_UsUrPeR__, sure
20:03
<_UsUrPeR__>
ok great
20:04
that's all
20:04
<alkisg>
_UsUrPeR__: kiosk mode?
20:04
<_UsUrPeR__>
alkisg: more of a Chrome OS replacement
20:04
but yeah
20:04
<alkisg>
I mean, you can use the ltsp kiosk plugin
20:04
And set KIOSK_EXE to chrome
20:04
Instead of writing your own screen scripts
20:04
<Hyperbyte>
The LTSP login prompt you see is called 'ldm', it's part of LTSP. It's ran inside X already, and it's launched via a screen.d script. There's also a screen.d script for kiosk mode, which just launches a browser instead of ldm.
20:05
<_UsUrPeR__>
alkisg: interesting.
20:05
alkisg: interesting. Does kiosk use a window manager?
20:05
i.e. gnome?
20:05
<alkisg>
No
20:05* _UsUrPeR__ looks for docs
20:06
<alkisg>
distro?
20:06
<_UsUrPeR__>
10.04 preferably
20:06
I think I found something: https://help.ubuntu.com/community/XkioskKiosk
20:07
<alkisg>
It has a bug in 10.04, search launchpad, there's a fix there
20:08
kiosksession file missing
20:08
<_UsUrPeR__>
ok great thanks
20:08
<Hyperbyte>
_UsUrPeR__, I think you just need to ltsp-build-client --kiosk and set SCREEN_07=kiosk in lts.conf
20:08
alkisg, right?
20:08
<alkisg>
Yes, and fix the bug
20:08
<Hyperbyte>
Yeah. :)
20:08
<alkisg>
And also install chrome and set KIOSK_EXE :)
20:10
<vmassuchetto>
