We use ipxe from a server, but using it from a local USB flash drive would work the same way. With NBD: :server1tftp imgfree echo Booting from LTSP 1 (TFTP) kernel tftp://192.168.1.12/ltsp/amd64/vmlinuz root=/dev/nbd0 init=/sbin/init-ltsp vt.handoff=7 nbdroot=192.168.1.12:/opt/ltsp/amd64 || goto server2 initrd tftp://192.168.1.12/ltsp/amd64/initrd.img || goto server2 boot || goto server2 (in this case, if it fails along the way, it tries from server2... || goto server2 ) If you want to speed up image loading, you can also use HTTP to load the image with ipxe (this helped us enormously when booting clients connected to the main network via a wireless bridge; for reasons beyond me TFTP was impossibly slow, HTTP works as fast as the bridge): :server1 imgfree echo Booting from LTSP 1 (HTTP) kernel http://192.168.1.12/vmlinuz root=/dev/nbd0 init=/sbin/init-ltsp vt.handoff=7 nbdroot=192.168.1.12:/opt/ltsp/amd64 || goto server1tftp initrd http://192.168.1.12/initrd.img || goto server1atftp boot || goto server1tftp Obviously this requires setting up a simple webserver to host the images. We use lighttpd. We also like to have some clients boot from one server, and some from another server, based on MAC address. This is also possible with ipxe: iseq ${netX/mac} ac:22:0b:c5:9f:b5 && goto server1 || #PC01 Graham ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
