Hello Stefan

The main hurdle in that kind of setup would be connecting to the wireless network before you mount the nfs share. I don't know if thats even possible

no, that is not what I want to do. I don't want mount the thinclient-root over nfs - like the tce over pxe does.

I just wanted a "local installation" of an thinclient-environment, which beheave like the tce.

That's quite easy - how I founded out now. What I've done:

• Installed x2gothinclientenvironment to a local debian installation
• setting up tce in a chroot like described in the wiki http://www.x2go.org/doku.php/wiki:components:tce
• chroot in the thinclient-chroot:

chroot /opt/x2gothinclient/chroot

changing the Boot-method in the initramfs (local instead of nfs)

vi /etc/initramfs-tools/initramfs.conf

# (...)
BOOT=local
# (...)

update-initramfs -u

(I had to install a newer kernel from backports becaus of brandnew hardware, simply adjusting /etc/apt/sources.list and upgrade the kernel)

Now installing stuff for wlan

apt-get install wpasupplicant wireless-tools firmware-b43-installer linux- wlan-ng-firmware atmel-firmware firmware-atheros firmware-brcm80211 firmware- iwlwifi firmware-linux-nonfree firmware-linux-free firmware-ralink firmware- realtek libertas-firmware

Configure network:

vi /etc/network/interfaces

  # Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
  # /usr/share/doc/ifupdown/examples for more information.
  auto lo
  iface lo inet loopback
   
  auto wlan0
  iface wlan0 inet dhcp
     wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

And adding the wireless config:

vi /etc/wpa_supplicant/wpa_supplicant.conf

  ap_scan=1
  ctrl_interface=/var/run/wpa_supplicant
  network={
         ssid="YOUR-SSID"
         scan_ssid=0
         proto=WPA RSN
         key_mgmt=WPA-PSK
         pairwise=CCMP TKIP
         group=CCMP TKIP
         psk=THEPRESHAREDKEY-SECRET-SECRET

For facilitate debugging setting up a password:

passwd

leaving the chroot.

exit

Now copiing the whole chroot to a harddisk or a usb-stick and install grub on the medium. For usb-stick it's easy:

mounting the partition (sdxX) with the chroot (/mnt):

/sbin/grub-install --root-directory=/mnt/ /dev/sdX

Finding out the UUID:

blkid

Now editing /mnt/boot/grub/grub.cfg (using the skelet of the existing installation) and adding:

menuentry 'x2go thinclient' { linux /boot/vmlinuz-3.2.0-0.bpo.1-686-pae root=UUID=UUID-OF-PARTITION ro initrd /boot/initrd.img-3.2.0-0.bpo.1-686-pae }

Now you have to edit your sessions:

vi /mnt/sdxX/etc/x2go/x2gothinclient_start

Ready.

Of course this is not yet perfect. E.g. it would be great to make the root-fs readonly, e.g. with squashfs. But it works so far.

One Problem is the lack of interactivity - if something goes wrong (maybe wifi is not running will disconnect during the session) than there is no meaningfull error message.

For laptops two additional things would be disirable: interactive wifi-manager (like network-manager or wicd) and a display for the battery charge.

So I tried to set up a minimal system with the same funcionality - but with an window-manager. This leaded to the problems I described in another mail: Error: Aborting session with 'Unable to open display

Greetings Stefan

Hi all,

we plan to set up an x2go-server in a school, where people should have access to with laptops throught wlan.

The laptops will have dual-boot systems an one of them should be a minimal setup with x2goclient (thinclient-image) and wlan access. It would be nice doing usb-automounting in the image - like the ltsp-thinclient environment does.

They should behave thin-client like - only that they can't boot through pxe because of wlan. (For the desktops we still use ltsp - because of features like local apps and automounging ...) So users should not have to open a desktop-environment, starting x2goclient and mount local devices manualy.

Are there any common approaches?

Is automounting working in the tce of x2go?

Thanks for your ideas.
