LiNbO stands for Linux-based Network Boot Console and is part of the so-called. 'Self-healing functionality' ( S ven healing end A rbeitsstationen, Sheila) the school server distributions paedML Linux (up to version 5.1) and the free Fork linuxmuster.net . LINBO uses the imaging principle for this , in which a changed operating system is replaced by a previously created memory image and thus restored. LINBO is the open source counterpart to Rembo .

Origin and development

Version 1 and 2

LINBO was developed by the Knoppix authors on behalf of the Baden-Württemberg State Media Center (LMZ). This should reliably ensure that the workstation computers used in the upper school level in the IT subject also function reliably in exam situations. The development began in July 2007 together with teachers seconded to the LMZ who supervised the paedML Linux and was completed after about a year with the publication of paedML 4.0 in July 2008, which included version 1.1.0. Under the umbrella of the Baden-Württemberg State Media Center, LINBO was further developed at an instance by Trac. With the appearance of paedML 5.0.1, the developers also published a new version of LINBO.

In February 2012, the State Media Center published version 2.0.9 as part of the paedML Linux 5.1 release.

With the announcement in July 2012 that the previous development of paedML Linux, of which LINBO is a component, was to be outsourced to a company, the State Media Center stopped development at LINBO.

Since then, LINBO has been further developed on GitHub by the linuxmuster.net open source community.

Version 2.1.1 was published on November 13th, 2012 by developers of the linuxmuster.net community.

Development of version 2.2 began in March 2014. New functions should include the integration of the OPSI client management and the computer-specific backup of activation data from a Windows 7 installation for offline reactivation. In addition, by switching to the LZMA - data compression algorithm are reduced LiNBO.

With the release of linuxmuster.net 6.1 in June 2015, the stable version 2.2.16 was released. In addition to the changes already mentioned, improvements were also made for clients that are connected to the school network via LAN or WLAN. In addition, commands executed once can now be sent linbo-remote -pto individual clients or entire client groups ( hardware classes ).

LINBO received an update to version 2.3 in July 2016 as a result of the release of linuxmuster.net 6.2. With the kernel update to 4.2 future there will be a native support for 64-bit -capable hardware . In addition, the change to GRUB 2 enables the operation of UEFI clients.

Version 3 was presented at the 12th Knoppix Days in Weiz at the end of August 2014. The development of this completely rewritten version began in August 2013. Among other things, it can manage virtual operating systems with the help of VirtualBox and the open source virtualization software VlizedLab . Through the tools used and the graphical interface used (consisting of a with HTML5 , Ajax and Django written website, the associated local Apache Web Server and Firefox ) is for the first time delivering an image an NFS - or SMB - Server requires. No public download of an installable software is known as the developers have decided to switch to a "From Scratch" system, based on the distribution kit principle, similar to Linux From Scratch . In June 2014, the source code of LINBOv3 and the graphical interfaces for the client and server were published on GitHub .

use

The Mini-Linux is loaded via PXE when a workstation computer is started in a paedML / openML / linuxmuster.net network and provides the option of loading either one of the local operating systems - LINBO thus acts as a boot manager - or the image of an operating system re-upload to the local hard drive. In the case of non-PXE-capable network cards, LINBO can be booted as a live CD in order to reload an image and then load it from the hard drive in the future. After changing a configuration, an image saved on the server can be updated on the server from any computer in the network, so no special master client is required. Since an image represents a complete memory image including the specific configuration of hardware settings and drivers, etc., the workstations must be divided into hardware classes and an image must be available for each hardware class. If the PC equipment is not uniformly equipped, it may be necessary to maintain several images. LINBO supports Linux distributions and Windows operating systems. The Windows images are registry - patches adapted to the local workstation. The package can also be integrated into other Linux distributions, e.g. B. at the Arktur school server .

Functions

  • Registration of workstation computers on the server
  • Management of several operating systems (boot manager)
  • Formatting the client hard drives
  • Creation and distribution of images (full and differential)
  • Repair or installation of a non-corrupted operating system (optionally possible every time the computer is restarted)
  • can be loaded locally or via PXE
  • Registry patcher to modify Windows installations
