Topic: boot thinclient to smeserver 9.1

[fhoffmann]

Hello,
I have installed on sme 9.1 dhcp, tftp, ubcd.iso; the thinclient gets a IP-address, a tftp prefix: ubcd/, it is loading pxelinux.cfg/default, then booting ubcd iso, loading memdisk....
And then appears "could not find ramdisk image: ubcd.iso"
Next line is: boot:
What should I do now?
Greetings

Post your config might help...

And as a follow up to that..... I think you either need to mount the iso via nfs or extract the contents of the iso and configure accordingly. There is a lot of info around if you search for "pxe boot ubcd" or similar.

A few extra notes....

I have a directory called /tftpboot/images where I keep the required files

I extracted the UBCD ISO into :

/tftpboot/images/UBCD/

Now look in /tftpboot/images/UBCD/ubcd/images and you should see various img.gz files

If you then look in /tftpboot/images/UBCD/ubcd/menus/syslinux you will see various config files for each of the applications above.

I basically copied the bits I wanted to a file called /tftpboot/pxelinux.cfg/diag which looks a bit like this :


[root@server pxelinux.cfg]# cat diag
menu title --== UBCD, UBCD Menu ==--
menu background graphics/background.png
menu tabmsgrow 22
menu cmdlinerow 22
menu endrow 24

With that you should get a menu for each application to run directly via tftp, rather than trying to load the whole ISO which will require NFS set up.

Makes life a bit easier.

Note partedmagic may take a little more messing with - look in /tftpboot/images/UBCD/ubcd/menus/syslinux/main.cfg for samples

Hello John,
thank you for yours answers. I am back from holidays and try again thinclients running. I have thought, that the ubcd.iso would be extracted when I added it in the thinclient configuration. How can I extract ubcd.iso in /tftpboot/ubcd/? You have asked me for my config. How can I post it to you?
Best regards.
Frank.

No, tftpd will not extract a file for you. It is extremely dumb. It just sends exactly what is asked and cannot do anything particularly complicated. You can search for 'pxe boot UBCD' or similar

As explained above you have two options:

NFS share the ISO
tftpd will then pass the entire iso to the client

Extract the required utilities and make each one available separately
tftpd will them pass each required utility to the client

To extract them you can loop mount the ISO - have a Google on how to do this

If you get stuck after some more searching please ask.
