Remote boot method

Abstract

The invention discloses a remote boot method. The method is used for remotely controlling a computer to boot. The remote boot method comprises the steps that standard preboot execution environment programme code is burnt in the computer; a basic input output system of the computer appoints a network card to guide the computer to boot; the basic input output system is executed, and whether to carry out remote boot or not is judged; when it is determined that the remote boot needs to be executed, the computer executes a preboot execution environment programme to drive the network card; the network card sends MAC addresses of the computer and a request for obtaining IP addresses to a server; the computer executes trivial file transfer protocol code and sends a dynamic host configuration protocol request to the server, and the server sends a response and allocates the IP addresses corresponding to the MAC addresses; and the computer receives the IP addresses and downloads and executes a network bootstrap programme on the server, thereby guiding the computer to enter an operating system.

Description

technical field [0001] The present invention relates to a method for remote start-up, in particular to a method for realizing remote start-up only supporting IPV6 technology. Background technique [0002] In the management of current computer systems, remote booting has gradually become an indispensable method and device. The current hardware architecture of remote booting can use the preboot execution environment (Preboot Execution Environment, PXE) standard model on the network card Standard Module (Standard Module) to implement remote booting, the action principle of this method is to burn a standard PXE program code into the Boot ROM of the network card of the computer or the BIOS of the motherboard. When the computer is turned on, the computer will be executed by the BIOS. If the computer has been set to be started by PXE, the BIOS will hand over the next execution right to the PXE program code, that is, execute the PXE program. When the PXE program obtains the executi...

[0004] In the above-mentioned Preboot Execution Environment (PXE), when the operating system of the computer obtains the IP address of the DHCP server, although the DHCP server server supports IPV&IPv6 address technology, it is stored in the network file system through TCP / IP network remote access (( Network File System, NFS), when the computer performs remote boot, after downloading the complete system core and the network card driver (the network DHCP client driver is mainly based on IPv4, and then do it according to whether there is IPv6 requirement Action, if the IPv4 protocol does not exist, the DHCP client driver will stop), and the action of requesting the DHCP server to obtain the DHCP IP address will be executed. For computers that only use IPv4 or (IPv4+IPv6) addresses for network startup, the Issue a request for assigning an IPv4 or (IPv4+IPv6) address. If the DHCP server only supports IPv6 (not including IPv4) addresses, the computer cannot obtain an IPv6 IP address from the DHCP server and cannot download from the DHCP / TFTP server. The operating system file executes the remote boot action, which largely limits the operating experience of the server and computer that support the pure (Pure) IPv6 address technology to achieve remote boot
