So far (No More, No Less, means that I have done only the following steps on a fresh TCL installation):
Putting it all together

The tftp server is sourced at /tftpboot. We are going to setup workstation1. It is going to have a /mnt/nfs that corresponds to /tftpboot/nfs/ws1. On the server myserver:

    mkdir -p /tftpboot/nfs/ws1/tce

    copy nfs-utils.tcz to /tftpboot/nfs/ws1/tce
-> Here I downloaded nfs-utils.tcz on option folder and I copied to the /tftpboot/nfs/ws1/tce

    create the file /tftpboot/nfs/ws1/nfs.list that contains: ^/nfs/ws1/nfs-utils.tcz^
^/nfs/ws1/nfs-utils.tcz^ -> do I have to put the ^ character before and after the file path?

    Copy tinycore.gz and bzImage to /tftpboot/nfs/ws1

    add ”/tftpboot/nfs/ws1 *(rw,no_root_squash)” to /etc/exports, and “exportfs -a”.
/etc/exports didn't exist as a result I created. It contains the following lines
Code: [Select]
/tftpboot/nfs/ws1 *(rw,no_root_squash)
exportfs -a
    Create a PXE config file that contains the following:
Code: [Select]
label ws1
  MENU LABEL WS1
  kernel /nfs/ws1/bzImage
  append initrd=/nfs/ws1/tinycore.gz nfsmount=myserver:/tftpboot/nfs/ws1 tftplist=myserver:/nfs/ws1/nfs.list tce=nfs/tce
Where I have to create this file?in which folder?What name should have?

When I solve my previous questions, I am going to do the following steps:
When you select ws1 from the PXE boot menu, the workstation does the following:

    Loads TCL.
    TFTP gets /nfs/ws1/nfs.list from myserver.
    TFTP gets each file listed in nfs.list and places it in /opt/tce.
    Mounts all applications in /opt/tce.
    Mounts myserver:/tftpboot/nfs/ws1 onto /mnt/nfs.

Any additional extensions installed by Appbrowser will be saved on the nfs share, and will be loaded during boot, just as you would expect with a local drive.

When you run the Backup-Restore utility, set the Device to nfs or nfs/tce.

There should be no "^" characters in your nfs.lst.
Do not put the boot files in the nfs tce directory.
/etc/exports should not contain "exportfs -a"
You do not need a tce= boot option.

Please re-read the netboot article.
Start with the absolute minimum method.

I started again to install the TCL using PXE boot.

Server (Ubuntu 10.04) -> destination Thin Client PXE boot.

In Ubuntu:
I installed tftpd-hda dhcpd3-server

then the configuration file /etc/default/tftpd-hpa
Quote
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="-s"
TFTP_DIRECTORY="/var/lib/tftpboot"

Then
Code: [Select]
wget http://distro.ibiblio.org/tinycorelinux/3.x/release/tinycore-current.iso
Next step :
Quote
mkdir /var/lib/tftpboot/tinycore

Next step :
Quote
mount -o loop tinycore-current.iso /var/lib//tftpboot/tinycore

folder boot contains:
Quote
/var/lib/tftpboot/tinycore/boot$ ls
bzImage  isolinux  tinycore.gz

my pxelinux.cfg now ONLY contains:
Quote
ebrachos@ebrachos-hp:/var/lib/tftpboot$ cat pxelinux.cfg

Question:

my thin client doesnt find something and skipped PXE boot.

I connected the thin client to my Laptop not to my router.
Do you think I have to connected it to my router?

Could someone examine the above lines to see if something goes wrong.

my router ip is 192.168.0.1 and my server 192.168.0.3

thanks.

I see both  192.168.1  and  192.168.0  listed. Is that a typo or are you really running two networks?

Hello
I've tried to run over PXE new TC, but X didn't start, system boots to command line. I think Ive got problem with loading tcz extensions ...
Ive tried almost everything loading them over tftp, nfs, http, boot tinycore iso over pxe but no success.
I've tried also tinycore 3.6 and it works great but I need to load new version because I need it with vmware view client

I tried to do this in this configuration:
pxeserver - VMware, SLES, syslinux-4.06, tftp-hpa-5.2

my pxe menu:
---------------
LABEL 4
        MENU LABEL TinyCore nfs
        KERNEL /nfs/ws1/boot/vmlinuz
        APPEND initrd=/nfs/ws1/boot/core.gz nfsmount=(ip_dhcp_server):/tftpboot/nfs/ws1
        TEXT HELP
        Boot the TinyCore nfs
        ENDTEXT
LABEL 3
        MENU LABEL VMWare View
        KERNEL vmview/memdisk
        APPEND iso initrd=vmview/vmview.iso raw
        TEXT HELP
        Boot the VM
        ENDTEXT
LABEL 2
        MENU LABEL TinyCore 3.6
        KERNEL tinycore/boot/bzImage
        APPEND initrd=tinycore/boot/tinycore.gz
        TEXT HELP
        Boot the TinyCore 3.6
        ENDTEXT
LABEL 1
        MENU LABEL TinyCore 4.7
        KERNEL image/boot/vmlinuz
        APPEND initrd=image/boot/core.gz cde
        TEXT HELP
        Boot the TinyCore new
        ENDTEXT

Can someone help me to resolve this problem?
Thank you very much

If you're not the original poster, I'd suggest creating a new thread/topic.

That said, I'd advise:
1) rereading http://wiki.tinycorelinux.net/wiki:netbooting http://wiki.tinycorelinux.net/wiki:remastering and http://wiki.tinycorelinux.net/wiki:dynamic_root_filesystem_remastering
2) I've done full PXE payloads with dynamic remastering for VMware View open client and Symantec Ghost with no issues.

Hi madeno
The GUI for Tinycore was broken out as separate components somewhere in the TC4.x release. It now requires
that the  Xvesa, Xprogs, Xlibs, flwm_topside, and wbar  extensions are available when booting. I don't know
if a  cde  directory is appropriate for PXE booting, but if it is, those extensions probably belong there. I don't
use PXE so someone else may have some better advice.

madeno, see:
This thread.

Basically, take the x extensions from the .iso and make another initramfs so that they extract into /tmp/builtin/optional, add it to your boot menu as a second initramfs and you should be good.
