Description
Technical field
The present invention relates to computer realm, specifically, relate to a kind of IP collocation method for (SuSE) Linux OS and device.
Background technology
Current internet has become a requisite part in people's live and work, and from network, obtaining information accounts for increasing ratio in the approach of people's obtaining information.The Internet is made up of countless nodes, and these nodes may be computer, router, switch etc., and wherein most node is computer.Be interconnected by medium physically between these nodes, medium comprises netting twine, optical fiber, electromagnetic wave etc., and uses ICP/IP protocol to intercom mutually.ICP/IP protocol is divided into the level that physical layer, data link layer, network layer, transport layer, application layer etc. are different.
An internet node wants to intercom mutually with another one node, will know the address of the other side each other.In ICP/IP protocol, different levels uses different addresses, to use in MAC Address, network layer the general use side slogan that to use in IP address, transport layer as address as in data link layer.In a node, MAC Address is for network interface card, and each network interface card has a MAC Address, and this MAC Address distributes in advance, can not arbitrarily change.IP address, for node itself, it represent the address of this node in the Internet.Port numbers is for application, and application different in node uses different port numbers.Can see that from description above the IP address of egress is most important a kind of address, which represent the position of this node in the Internet, and IP address freely can configure.
The mode of current configuration of IP address has two kinds: configuration and manual configuration automatically.It is DHCP technology that automatic configuration uses usually, and this technology places a Dynamic Host Configuration Protocol server in a network, node initiatively to Dynamic Host Configuration Protocol server application IP address, the management of IP address is completed automatically by Dynamic Host Configuration Protocol server.Manual configuration is by the IP address of the manual configuration node of the manager of node, normally use the IP address of " ifconfig " command configuration node under Linux, wherein, ifconfig order is the order for display or configure network devices (network interface unit) in linux operating system.
But, due to various reason, for the configuration mode of the IP address of node, the mode still manually configured be widely used at present realizes the IP address configuration to node, under current Linux, manual configuration of IP address is the configuration using " ifconfig " order to carry out IP address in most cases, but the IP address that this collocation method is very easy to appear as Joint Enterprise is identical with the IP address of other node, namely easily there is the IP collision problem of each node, and IP address is as node unique identification in a network, if generation IP address conflict, not only can cause having conflict two, IP address node can not with other node communication, also easily cause the paralysis of whole network.
For IP address manual in correlation technique configuration mode existing for the problem of IP address conflict easily causing configuring, at present effective solution is not yet proposed.
Summary of the invention
For the problem in correlation technique, the present invention proposes a kind of IP collocation method for (SuSE) Linux OS and device, can avoid conflicting mutually to the IP address of each Joint Enterprise in network, thus avoid network communication failure and network paralysis problem that IP address conflict causes.
Technical scheme of the present invention is achieved in that
According to an aspect of the present invention, a kind of IP inking device for (SuSE) Linux OS is provided.
This device comprises: receiving element, the generation unit be connected with receiving element and the detecting unit be connected with generation unit, wherein,
Receiving element, needs configuration to the target ip address of present node for receiving and sends;
Generation unit, for receiving target IP address, and based target IP address generates Target IP request message and sends, and wherein, comprises target ip address in Target IP request message;
Detecting unit, for detecting the recall signal corresponding to Target IP request message, wherein, detecting unit comprises transmitting element and dispensing unit, and wherein, transmitting element, for when recall signal being detected, sends error signal; Dispensing unit, for when recall signal not detected, is configured according to the IP of target ip address to present node.
Wherein, detecting unit, for detecting the recall signal corresponding to Target IP request message within the predetermined time.
In addition, this device comprises further:
Report an error unit, for when receiving error signal, generating the error message of target ip address and sending.
Preferably, the type of Target IP request message is Internet Control Message Protocol icmp packet.
According to another aspect of the present invention, a kind of IP collocation method for (SuSE) Linux OS is provided.
The method comprises:
Receive the target ip address needing configuration to present node;
Based target IP address generates Target IP request message, wherein, comprises target ip address in Target IP request message;
Detect the recall signal corresponding to Target IP request message, wherein, when recall signal being detected, sending error signal, when recall signal not detected, being configured according to the IP of target ip address to present node.
Preferably, the recall signal corresponding to Target IP request message is detected within the predetermined time.
In addition, the method comprises further:
When receiving error signal, generating the error message of target ip address and sending.
Preferably, the type of Target IP request message is Internet Control Message Protocol icmp packet.
The present invention, by detecting IP address before configuration of IP address, effectively avoids the conflict of IP address between each node, thus the serious problems such as the network service identification preventing IP address conflict to bring or network paralysis.
