XenobootXenoBoot is our system for performing remote boot and management of x86 machines scattered over the public Internet. It provides a convenient way controlling the boot process of a remote machine, enabling, for example:
These facilities are provided in an authenticated and secure manner suitable for use across the public Internet. The system is flexible, enabling booting of pretty much any type of kernel, and remote administration of most file system types. The system is also relatively failsafe, able to recover the system even in the presence of gross corruption of the hard disk. This is achieved through using a bootable CD image, which due to its read-only nature should enable the system to boot in any event except hardware failure or certain corruptions of the BIOS NVRAM. The bootable CD loads a full linux operating system, and then contacts a central server, which gives it a script to run. The script has access to a range of utilities and applications on the CD, and can be tailored to fit the individual machine and circumstance. XenoBoot avoids the need for remote serial console servers to administer machines - everything can be done over a secure network connection. For resetting "wedged" machines we either use hardware watchdog cards, or for extra reliability, remote power control switches.
DownloadsThe current version of the Xenoboot CD is v2.3; you can download it here. The README file is here. To customize, build and use the CD, you'll need:
If you have any questions or feedback about Xenoboot, email Tim Deegan.
Most of the software on the CD is taken from the
gentoo linux distribution; source
code is included, and is also available via
gentoo.
The previous version was 2.2. You can download a much older version (v1.1) of the Xenoboot CD here. (You'll need to have mkisofs and SOAP::Lite installed to use it.) |
