Detailed Description
The core of the application is to provide a method and a device for monitoring client renewal, a DHCP server and a readable storage medium, which realize the automatic monitoring of a large number of client renewal states.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a first embodiment of a method for monitoring client renewal provided by the present application is described below, where the first embodiment is implemented based on a DHCP server, and includes:
s101, acquiring the time of the current appointment of the target client from a local lease file by using an automatic script;
s102, judging whether the current appointment is abnormal or not according to the time of the current appointment and the time of the last appointment of the target client; if the abnormal condition exists, jumping to S103, otherwise, not processing;
and S103, generating prompt information of the target client side for renewing abnormity.
DHCP (dynamic Host Configuration protocol), namely, a dynamic Host Configuration protocol, is designed and developed by an Internet task force, and a protocol for automatically allocating TCP/IP parameters to a computer in a TCP/IP network by a special user. The DHCP protocol works in a Client/Server mode, the DHCP Server is responsible for allocating and managing IP addresses, and the DHCP Client requests the DHCP Server to allocate the IP addresses.
There are three mechanisms for DHCP to allocate IP addresses, and this embodiment mainly considers a dynamic allocation manner. In the dynamic allocation mode, the DHCP server allocates an IP address with a time limit to the client, and when the time expires or the client explicitly indicates that the IP address is abandoned, the DHCP server will reclaim the address.
If the client wants to continue using the IP address, a renewal request must be sent to the DHCP server, in a specific way: when the service lease exceeds a half, the client sends a renewal Request to the DHCP server, namely sends a DHCP Request message to renew the IP address. After receiving the lease request, the DHCP performs lease operation, updates lease time, and sends a message that the lease is successful, that is, a DHCP ACK message to the client. And after the client successfully receives the message of successful renewal, prolonging the IP address lease according to the updated lease time. If the client has not renewed, the client may continue to use this IP address until the IP address lease time expires, which the DHCP server will reclaim.
In this embodiment, the lease file is a DHCP.
As a specific implementation manner, the latest renewal time of the target client is acquired from the lease file at preset time intervals, and is different from the last renewal time of the target client, whether the renewal is overtime is judged according to the time difference, that is, whether the time difference falls into a reasonable range is judged, if not, the renewal of the current time is judged to be abnormal, and the user is prompted that the renewal of the target client is abnormal.
The method for monitoring client renewal provided by the embodiment is applied to a DHCP server, and the scheme comprises the following steps: acquiring the time of the current appointment of the target client from a local lease file by using an automatic script; judging whether the current appointment is abnormal or not according to the time of the current appointment and the time of the last appointment of the target client; and if the client is abnormal, generating prompt information of the target client for renewing the abnormity. Therefore, according to the scheme, the information of the client without normal Renew IP can be captured from the information of a large number of clients through the automatic script, the client is prompted to have abnormal renewal, the automatic monitoring of the renewal state of the client is realized, and the problems of large time consumption and low efficiency caused by manually searching lease files are solved.
A second embodiment of the method for monitoring client continuation provided by the present application is described in detail below, and the second embodiment is implemented based on the first embodiment and is expanded to a certain extent based on the first embodiment.
Consider that a dhcp. Therefore, the embodiment captures lease information of the target client from the dhcp.
In addition, when a problem occurs in the continuation, it cannot be determined whether the client can normally acquire the IP, or whether the information related to the BMC after acquiring the IP can be captured normally. Therefore, the embodiment adds a detection process, that is, a process of detecting whether normal communication with the BMC of the target client can be performed according to the IP address.
Referring to fig. 2, the second embodiment is implemented based on a DHCP server, and includes:
s201, judging whether an MAC address exists in a local dhcp. If yes, jumping to S202; otherwise, judging again after the preset time length;
s202, capturing the MAC address and the corresponding IP address from the dhcp.
S203, judging whether normal communication can be carried out between the local IP address and the BMC of the target client side; if yes, jumping to S204; otherwise, jumping to S207;
s204, obtaining the time of the target client for the current appointment from the dhcp.
S205, determining the time difference between the time of the current offer and the time of the last offer of the target client;
s206, judging whether the time difference is less than or equal to 0 or whether the time difference is greater than lease time, if so, judging that the renewal is abnormal, and jumping to S207; otherwise, judging that the appointment continuation is normal, and jumping to S208;
s207, recording the MAC address and the IP address of the target client and the time of the current appointment into a preset abnormal file, and jumping to S201;
and S208, recording the MAC address and the IP address of the target client and the time of the continuation into a preset normal file, and jumping to S201.
Therefore, the method for monitoring client renewal provided by the embodiment is applied to a DHCP server, can capture information of a client without normal Renew in IP from a large amount of information of the client through an automatic script, records abnormal time and gives a prompt, realizes automatic monitoring of the client renewal state, and avoids the problems of large time consumption and low efficiency caused by manually searching lease files.
In the following, a device for monitoring client renewal provided by the embodiments of the present application is described, and a device for monitoring client renewal described below and a method for monitoring client renewal described above are referred to in correspondence.
