Abstract
The invention provides a method for discovering multi-network card equipment based on a specific video protocol, which comprises the following steps: s1, sending an onvif protocol request to an IP to be detected; s2, obtaining onvif protocol data in an xml format, and analyzing the xml; s3, judging whether the field'd: XAddrs' in the xml contains a plurality of urls or not, wherein the IP addresses of the hosts contained in the urls are different; if yes, go to step S4, otherwise go to step S5; s4, detecting that the equipment has a plurality of network cards; and S5, the detected equipment does not have a multi-network card. Different from the traditional method for detecting multiple IP or multiple network card devices, the method can effectively identify the device starting the Onvif protocol; meanwhile, the problems of opening a firewall and the like can be effectively solved, and the discovery rate of multiple IP or multiple network card devices is improved.
Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of network security detection, in particular to a method for discovering multi-network card equipment based on a specific video protocol.
[ background of the invention ]
ONVIF (open Network Video Interface forum), which is an open Network Video Interface forum, provides a unified Network Video development standard, that is, integration between different products can be realized through the standardized platform ONVIF. In the security monitoring industry, the ONVIF protocol will become the first choice in the network video field for a long time. The ONVIF standard will define a common protocol for information exchange between network video devices, including device search, real-time video, audio, metadata, and control information, among others. The multiple possibilities offered by the network video product allow end users, integrators, consultants and manufacturers to benefit easily from it, and to achieve cost-effective, more flexible solutions, opportunities for market expansion and lower risks.
[ summary of the invention ]
The invention aims to solve the problem that multi-IP or multi-network card equipment accessed to a network cannot be effectively discovered and detected in the prior art, and provides a method for discovering multi-network card equipment based on a specific video protocol.
In order to achieve the above object, the present invention provides a method for discovering multiple network card devices based on a specific video protocol, which comprises the following steps:
s1, sending an onvif protocol request to an IP to be detected;
s2, acquiring onvif protocol data in an xml format, and analyzing the xml;
s3, judging whether the field'd: XAddrs' in the xml contains a plurality of urls or not, wherein the IP addresses of the hosts contained in the urls are different; if yes, go to step S4, otherwise go to step S5;
s4, detecting that the equipment has a plurality of network cards;
and S5, the detected equipment does not have a multi-network card.
Preferably, the onvif information of the device is acquired through collection and analysis of network traffic and onvif protocol scanning.
Preferably, in step S1, if the onvif information is not acquired, the process proceeds directly to step S5, and otherwise, the process proceeds to step S2.
The invention has the beneficial effects that: different from the traditional method for detecting multiple IP or multiple network card devices, the method can effectively identify the device starting the Onvif protocol; meanwhile, the problems of opening a firewall and the like can be effectively solved, and the discovery rate of multiple IP or multiple network card devices is improved.
The features and advantages of the present invention will be described in detail by embodiments in conjunction with the accompanying drawings.
[ description of the drawings ]
Fig. 1 is a flow chart of a method for multi-network card device discovery based on a specific video protocol according to the present invention.
[ detailed description ] embodiments
Referring to fig. 1, the method for discovering a multi-network-card device based on a specific video protocol of the present invention acquires the onvif information of the device by collecting and analyzing the onvif protocol scan of the network traffic, and discovers whether the device has a multi-IP condition. The method specifically comprises the following steps:
s1, sending an onvif protocol request to an IP to be detected, if the onvif information is not acquired, directly entering a step S5, otherwise, entering a step S2;
s2, acquiring onvif protocol data in an xml format, and analyzing the xml;
s3, judging whether the field'd: XAddrs' in the xml contains a plurality of urls or not, wherein the IP addresses of the hosts contained in the urls are different; if yes, go to step S4, otherwise go to step S5;
s4, detecting that the equipment has a plurality of network cards;
and S5, the detected equipment does not have a multi-network card.
Different from the traditional method for detecting multi-IP or multi-network card equipment, the method of the invention can effectively identify the equipment which opens the Onvif protocol. Meanwhile, the problems of opening a firewall and the like can be effectively solved, and the discovery rate of multi-IP or multi-network card equipment is improved.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
