Network boot live ISO

January 29th, 2014 by

The x86_64 edition of openSUSE Education’s Li-f-e live DVD supports PXE booting the iso over the network, here is how to do it:

* Install Li-f-e (Switch to GRUB from Installation Summary page if your hardware does not support EFI boot ), make sure you have plenty of space assigned to / partition(about 20G)
* Set up LTSP by following this quick start guide
* Create /srv/nfs folder and copy Li-f-e iso there
* Run the following as root in terminal:

mount /srv/nfs/openSUSE-Edu-li-f-e.x86_64-13.1.1.iso /mnt
cp /mnt/boot/x86_64/loader/linux /srv/tftpboot/boot/linux-life64
cp /mnt/boot/x86_64/loader/initrd /srv/tftpboot/boot/initrd-life64
echo "/srv/nfs *(ro,no_root_squash,async,no_subtree_check)" >> /etc/exports
cat <<EOF>> /srv/tftpboot/pxelinux.cfg/default
LABEL Li-f-e
kernel boot/linux-life64
append initrd=boot/initrd-life64 isofrom_device=nfs:10.0.0.254:/srv/nfs/ isofrom_system=/openSUSE-Edu-li-f-e.x86_64-13.1.1.iso nonm
IPAPPEND 2
EOF
chkconfig rpcbind on && service rpcbind restart
chkconfig nfsserver on && service nfsserver restart

Now you can PXE boot any machine over the network, select Li-f-e from the end of the boot menu to boot live DVD iso instead of normal LTSP session.

Please note that if you install Li-f-e booted over the network then after the installation you will need to remove “nonm” boot option using yast2 bootloader to get NetworkManager working again.

Coming soon on the servers near you: Easy-LTSP-NG

June 2nd, 2009 by

Easy-LTSP, an easy to use GUI to configure LTSP‘s lts.conf file was developed as a part of Google Summer of Code ’08 by Jan Weber. It was written in C#, it was decided to use C# at that time to accomplish a complex task in a very short period of time given for GSOC. Thanks to it setting up LTSP on openSUSE is just a few mouse clicks.

Easy-LTSP was designed to work on any distribution, but unfortunately it is not integrated anywhere other than openSUSE, discussing with the upstream LTSP developers suggested the slight reservation could be due to it being written in C#. We wanted to add new features to the GUI to take care of all the exciting new development we have in KIWI-LTSP so it was felt that the rewrite will be much better option than to extend the current code, as it is anyway being written from scratch why not use something like Python which would be easier to attract more contributors and increase possibility that users of all distributions running LTSP server can benefit from it inclusion in their prefered distro.

Here are the screencaps of the “Next Generation” Easy-LTSP(click image to see full album):

The code is in very initial stage, many things do not work yet, these screenies would give some idea where the design is going. If you are a developer interested in hacking get the source from here, drop us a line if you want SVN commit access. If you are a user and have some suggestions or an idea how this tool should be like file an enhancement request on devzilla here.
