v38 v39 2 2 3 3 = PXE-utilities = 4 This is a release of the S ARApackage of utilities that we use to boot our nodes with PXE-enabled network cards. This was developed because we always want to use the PXE-enabled network card as our first boot device. With [http://syslinux.zytor.com/pxe.php pxelinux], which is a derivative of [http://syslinux.zytor.com/ syslinux], you can specify with a PXE configuration file how the node must boot. This configuration is placed in, e.g. ''/tftpboot/pxelinux.cfg'' directory.4 This is a release of the SURFsara package of utilities that we use to boot our nodes with PXE-enabled network cards.

The default setup is to boot from hard disk. When a node boots it fetches the default configuration file and the configuration file instructs the node to boot from the hard-disk. At S ARAwe have developed the following strategy to install a fresh node:19 We have a default setup. The default setup is to boot from hard disk. When a node boots it fetches the default configuration file and the configuration file instructs the node to boot from the hard-disk. At SURFsara we have developed the following strategy to install a fresh node: 20 20 21 21 1. The ip-address in our setup is known for the new node. So we make a link in the ''/tftpboot/pxelinux.cfg'' directory to a pxe configuration file which instructs that it has to fetch the kernel and root filesystem from our boot server, eg: {{{ 0A000A02 ---> default.node_install (10.0.10.2) }}}
