lstp client login blank for lstp server on ubuntu 14.04 , what I'm missing here..?

[aravinda2]

I am trying to configure a lstp server ( `ip of lstp server : 172.16.40.0` ) on a `64bit ubuntu 14.04` and check it network booting virtualbox vm (harddisk less vm)
I configured everything according to this doc http://ubuntuforums.org/showthread.php?t=2173749


But when I enter root user and password in "virtualbox vm ltsp client", It boots perfect, authenticates perfect.. but not loading desktop.. I mean not loading unity kind of desktop.. just blank..







Here are the things I did while configuring lstp server


First Updated the server

 sudo apt-get update && sudo apt-get upgrade

Then install LTSP, a proxy DHCP server, and a TFTP server:


s

udo apt-get install ltsp-server dnsmasq tftpd-hpa

Client operating system image built using

 sudo ltsp-build-client --arch i386

Then, to enable support for proxy DHCP by default i ran

sudo sed -i 's/ipappend 2/ipappend 3/g' /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

and here is my configured `ltsp.conf` at `/etc/dnsmasq.d/ltsp.conf`

#
    # Dnsmasq running as a proxy DHCP and TFTP server
    #
    # See: http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html
    #
    
    #
    # TFTP
    #
    
    # This might work instead of tftpd-hpa:
    #enable-tftp
    #tftp-root=/var/lib/tftpboot
    
    #
    # DHCP
    #
    
    # DHCP proxy on this network
    dhcp-range=172.16.40.0,proxy
    
    # Tell PXE clients not to use multicast discovery
    # See section 3.2.3.1 in http://tools.ietf.org/html/draft-henry-remote-boot-protocol-00
    dhcp-option=vendor:PXEClient,6,2b
    
    # Better support for old or broken DHCP clients
    dhcp-no-override
    
    # Enable this for better debugging
    #log-dhcp
    
    #
    # PXE
    #
    
    # Note the file paths are relative to our "tftp-root" and that ".0" will be appended
    
    pxe-prompt="Press F8 for boot menu", 3
    pxe-service=x86PC, "Boot from network", /ltsp/i386/pxelinux
    pxe-service=x86PC, "Boot from local hard disk"

Then restarted service `sudo service dnsmasq restart`


**(Tried without `/var/lib/tftpboot/ltsp/i386/lts.conf` and same result of above blank desktop when booting vm client.. )**




Then go ahead and edited, `/var/lib/tftpboot/ltsp/i386/lts.conf`


added

 [Default]
    LDM_DIRECTX = True

then updated image and run the following

sudo ltsp-update-image


    sudo sed -i 's/ipappend 2/ipappend 3/g' /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

Please note: Since they have stated in the above tute " that on Ubuntu 14.04, there is currently a bug with tftpd-hpa" I edited `/etc/init/tftpd-hpa.conf` according to this https://bugs.launchpad.net/ubuntu/+s...09/comments/40


and here is my `/etc/init/tftpd-hpa.conf`

.

Here is a Sample lts.conf file in case you need to edit anything. Look at the lines that are bold and uncomment the line for gnome-fallback and see if it loads the gnome-fallback in the clients.


unhappyghost@unhappyghost:$ sudo nano /var/lib/tftpboot/ltsp/i386/lts.conf


[default]
# X_COLOR_DEPTH = 24 # to set the color depth on display
# LOCALDEV = True # use local hardware on clients
# SOUND = True # use sound drivers on clients
# NBD_SWAP = Y # use swap to be set on server
# SYSLOG_HOST = server # use server as syslog_server
# XKBLAYOUT= en # keyboard default to en
# SCREEN_07 = rdesktop
# RDP_OPTIONS = "-a 16"
# RDP_SERVER = 192.168.5.99 # IP Address of the Windows Terminal Server with AD
# LDM_ALLOW_GUEST = True # enable guest logins, for old edubuntu
# LDM_GUESTLOGIN = True # enable guest logins, for newer edubuntu
# LDM_THEME = edubuntu # set theme folder - edubuntu, ltsp, default
LANG = en_US.UTF-8
LANGUAGE = en_US.UTF-8
LDM_LANGUAGE = en_US.UTF-8
# LDM_SESSION = "gnome-session --session=gnome-fallback" #For Ubuntu Gnome Desktop!!!
# LDM_REMOTECMD = /usr/bin/startkde #For Ubuntu Unity UI Desktop!!!




ctrl+O to save the changes
ctrl+X to exit nano editor

after the changes to the lts.conf file you have to issue the below mentioned ltsp-update commands after every change
Also you mentioned that it authenticates but the desktop doesn't load, so the sshkeys may be the problem.


unhappyghost@unhappyghost:$ sudo ltsp-update-kernels
unhappyghost@unhappyghost:$ sudo ltsp-update-sshkeys
unhappyghost@unhappyghost:$ sudo ltsp-update-image

Could you please share the configuration in the following files
/etc/default/tftpd-hpa
/etc/dnsmasq.d/ltsp.conf
/var/lib/tftpboot/ltsp/i386/lts.conf

Am having trouble setting up the ltsp server and so may be looking at your configuration files and comparing with the ones i configured, i will be able to figure out where did i do wrong.
