Technical Field
The invention relates to the field of computing application, in particular to a method, a device and a system for setting a DNS (domain name system) server address on a MacOSX operating system.
Background
The existing internet operates on the basis of the IPv4 protocol. IPv6 (internet protocol version6, version6 of the internet protocol) is the next version of the internet protocol, and its proposal was originally made because with the rapid development of the internet, the limited address space defined by IPv4 will be exhausted, and the shortage of the address space will certainly affect the further development of the internet. IPv6 has: the method has the advantages of expanding the address space, improving the overall throughput of the network, improving the quality of service (QoS), better ensuring the security, supporting plug and play and mobility, better realizing the multicast function and the like. The DNS (Domain name System) server is used for binding the domain name and the IP address on the network, so that the user can access the site corresponding to the IP address by directly inputting the domain name in the browser.
The automatic configuration of the IP address of the host in the IPv6 protocol is currently implemented with the following methods:
full state auto configuration (stateful auto configuration):
the configuration is performed based on the DHCPv6 protocol, and by applying for an IP address from a DHCP (dynamic host configuration protocol) server and obtaining related configuration information (such as a default gateway, a DNS server, etc.), the IP address configuration method is substantially the same as IPv 4.
However, all versions (10.4 version/10.5 version/10.6 version) of the MacOSX operating system (personal computer operating system of apple inc.) do not support the DHCPv6 protocol, and only the IPv6 address can be configured through the ICMPv6 protocol, but the ICMPv6 protocol only can configure the IP address, but does not support obtaining other configuration information, such as the DNS server address, and the like, so the DNS server address under the MacOSX operating system needs to be manually set by the user at the network configuration interface. When network service is provided for a host running a MacOSX operating system by using a network access terminal device (such as a network access card, a data card, a modem and the like), the IPv6DNS server address of the host cannot be automatically configured, only manual configuration can be performed by a user, and the problems of complicated manual configuration operation and low efficiency exist.

The method of the embodiment of the present invention will be described in further detail with reference to fig. 4.
The host running the MacOSX operating system is in communication connection with the internet-surfing terminal equipment, a driving program and a resident process (namely a resident memory service process which is a resident process for obtaining the highest administrator authority of the MacOSX operating system running by the host) matched with the internet-surfing terminal equipment are installed on the host, the host can be connected to an IPv6 network through the internet-surfing terminal equipment, and DNS information is transmitted to the driving program of the internet-surfing terminal equipment after the internet-surfing terminal equipment is connected to the IPv6 network; the driver passes through the DNS information to the resident process, and the resident process calls an application program interface function (API) of the MacOSX operating system to set the DNS information into the host.
As shown in fig. 4, step 41 is: a driver (a driver matched with the internet surfing terminal) running on a host of the MacOSX operating system is connected with the internet surfing terminal equipment in an IPv6 mode;
step 42 is: the host receives a connection notification sent by the internet-surfing terminal equipment through a driving program running on the host;
step 43 is: the host inquires an IP address to the network terminal equipment through an ICMPv6request by a driver running on the host;
step 44 is: the host receives an IP address returned by the Internet surfing terminal equipment through ICMPv6response through a driving program running on the host;
step 45 is: an operating system running on the host automatically configures the IP address of the host according to the IP address obtained by a driving program running on the host;
step 46 is: the host inquires a DNS server address from the network terminal equipment through an inquiry command by a driving program running on the host;
step 47 is: the host receives a DNS server address returned by the internet-surfing terminal equipment through a driving program running on the host, and transmits the DNS server address to a resident process which has obtained root authority and runs on the host;
step 48 is: the resident process running on the host calls the API of the MacOSX operating system to set the DNS server address using the received DNS server address.
In the flow of fig. 4, steps 41 to 44 belong to a process of establishing an IPv6 connection and acquiring an IP address through an ICMPv6 command; in step 46, the host queries the DNS server address from the internet-accessing terminal device through the driver running thereon; in step 47, the host transmits the DNS server address to the resident process running on the host through the driver running on the host; the DNS server address of the host is set by the resident process running on the host calling the system API in step 48.
In the method, the resident process running on the host computer already has root authority (namely the highest administrator authority of the system, otherwise, the API for setting the DNS server address cannot be executed) when the resident process is installed; this enables automatic start-up each time the operating system of the host is restarted.
By the method provided by the embodiment of the invention, after the IPv6 network connection is established on the MacOSX operating system, the DNS server address of the host can be automatically configured without manual operation of a user.
