Title: Howto for Zentyal Thin Client Module
Post by: ira on September 14, 2012, 04:23:33 am
Hi there. I've been working with the thin client module (LTSP) for a while now so I thought it would be helpful to make a post of my findings. I've tried this module in two following ways - With Zentyal 3.0 as the main DHCP Server in a network and as also a stand-alone thin client server in a network that already has a DHCP server (dnsmasq).

Kerberos is the authentication method for users in 3.0 so your kerberos realm needs to be setup correctly. In the DNS module your realm (e.g. EXAMPLE.COM) needs to be set resolve to the ip of the interface that the kerberos server (kdc) is listening on (ports 8880 and 8464). If it is an external interface that you want to use then you will need to add a firewall rule.

If your network interface gets an ip address via DHCP then the DHCP server usually provides the client with a DNS server to use. If this happens then the zentyal realm will need to be in DNS records of the DNS server and resolve to the zentyal ip.


Setup steps for Zentyal 3.0 as DHCP and Thin Client Server:

Setup steps for zentyal as stand-alone thin client server with only one network card:

Same as above but..
Troubleshooting:



Hope this guide helps someone out. If anyone needs help with this module I'll try to give a hand. Now I'm off to try and bulk import users to in LDAP  ;D[/list]

Excellent work ira!
This will enable pxe booting from Zentyal server, may I add - You can use grub4dos as a bootfile and boot a whole range of images right from the server.
It will take some time before I can test this, but once tested I'll give some feedback.

Cheers.

I will fill up the list of problems:
if you have local a repository, you should edit 2 files, having specified in them the address of your repository.

Cool! What about moving this Howto to the wiki?

Stuart, please trust me  ;)
Stop posting everywhere tons of messages that are only post to other of your own messages.
I acknowledge that sometime it helps, avoiding to repeat same thing but, if you look at your stats, you will notice that more than 40% of your messages are redirect toward... your messages  ::)  ::)
Try to refrain yourself  ;D  of add some comment to your link, at least to make it clearer  8)

Just trying to get a response chris. Was trying to lump all us LTSP adventurers together.

I often just post the link rather than just repeat the same stuff. It would be great to be able to lump similar together so we are all not repeating stuff.

I think you know I am really interested in LTSP but hitting a few problems and one of how to employ it.

How about you giving me a break on this one but offering your broad knowledge on the topic?

PS I think you will find that a lot of it is because I make a reply to one of my own messages so I can work with the upload limitation.

Yuri if LTSP included --copy-sourceslist --apt-keys then the current sources.list and keys would be pulled into ltsp.

Would you generally like to see more options here?

Hello everyone.

I tried to follow this how to, but after I have installed

Code: [Select]
sudo apt-get install ubuntu-desktop network-manager-
I'm not able to login with ldap users on the GUI(LightDM).

With ssh, I'm still able to authenticate.
kinit command is giving the expected results

Before this command, I was able to authenticate with the default desktop gui.

Thank you

You already posted same question here (http://forum.zentyal.org/index.php/topic,12510.0.html).
Please do not cross-post, it doesn't help getting answer faster but makes things confusing instead  :-[

I would like to ask if there is any problem if I install Lubuntu/LXDE instead of ubuntu/unity as the desktop manager for thin clients

From my experience, thin client woks with LXDE(which is the default DE on Zentyal )

I've just made it at home. I'm pretty newbie with this kind of things: I'm using zentyal for school (I'm studying to become a server administator/network technician) and I'd like to know if its possible to run my thinclients from outside my home LAN

  thanks for you time & help..this guide is quite helpful for noobs like me

PD: my zentyal server is already configured to be accesible from outside my LAN, I use the cloud module for dynamicDNS and I can access zentyal webmin interface and ssh (and the users I've created too) but I'd like to know:
1- what should I configure in the server
2-and where do I have to point the client to access the thinclients images hosted in my zentyal server from outside my homeLAN

Steup Thin Client and created image. Logged in via VirtualBox and everything worked -- Until I tried to login to the thin client from the Ubuntu default login screen. I enter valid username and password and it just recycles to the login screen.

Has anybody else experienced this? If so, is there a post with a soultion?

Thanks

I just want to ask if it is "safe" to erase the thinclient image to build a new one..

I've got a new zentyal deployment, and after building the thinclient image I've added some new apps that I'm gonna need in the thinclients (no fat clients) and now I don't know how to add those apps to the thinclient image, so I've thought the only solution is to build a new one, but I dont see any gui option for that, so...

..should I use the command line to erase my image?  will I have any problem later to build a new one with zentyal gui?

thanks..this topic has been really useful for me while Ive been installing and configuring the thinclients module..

PD: I still don't know how to access my thinclients from outside my home LAN..where can I find some documentation for that?

Hello, I can't seem to figure out how to point my virtualbox machine to the thin client image/server. I have a home-class router, any ideas as to how to use this with virtualbox for testing and a HP T5730 thin client for regular use?
