Problems solved by technology

[0004] It can be seen that if the client wants to detect the status of the target server, it must first enable the ICMP policy for the client on the target server, and the maintenance cost is relatively high.
[0005] In addition, each server often has multiple service ports. When the server is available, only some service ports may be available, while the remaining service ports may not be available.
By sending Ping messages, the client can only detect whether the server is available, but cannot detect whether a specific service port is available, and the detection accuracy is poor.

Embodiment Construction

[0025] When the present invention needs to detect the state of the target server, it establishes a TCP connection with the target service port of the target server, and judges the state of the target service port according to the response message returned by the target server. For details, please refer to figure 1 .

[0026] figure 1 It is a flow chart of the detection method of the server state provided by the present invention.

[0027] Such as figure 1 As shown, the method includes:

[0028] Step 101, when it is necessary to detect the state of the target server, the client sends a SYN request of the TCP protocol to the target service port of the target server.

[0029] Step 102, the client receives the response message returned by the target server.

[0030] Step 103, the client judges the status of the target service port according to the response message.

[0031] In this step, the client identifies the type of the response message returned by the target server, and...

Abstract

The invention discloses a method and a device for detecting server status. The method for detecting server status comprises the following steps: when the status of a target server needs to be detected, a client side transmits a synchronize (SYN) request of a transmission control protocol (TCP) to a target service port of the target server, receives a response message returned by the target server, and judges the status of the target service port according to the response message. By means of the method and the device for detecting server status, maintenance cost for detecting the server status can be lowered, and detection accuracy can be improved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and device for detecting the state of a server. Background technique [0002] In Internet services, it is often necessary to detect the server status. Currently, a Ping message of the Internet Control Message Protocol (Internet Control Message Protocol, ICMP) is usually used to detect the server status. [0003] Specifically, the monitored server side enables an ICMP policy for a specific client, and then the client can send a Ping message to the monitored server, so as to detect whether the monitored server is currently available. [0004] It can be seen that, if the client wants to detect the state of the target server, it must first enable the ICMP policy for the client on the target server, and the maintenance cost is relatively high. [0005] In addition, each server often has multiple service ports. When the server is available, only some service ports m...
