Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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.
The client hostname processing method provided by the embodiment of the application can be applied to a client hostname processing system as shown in fig. 1, wherein a display client can communicate with a DHCP server through a network. The display client is used for sending a client management page query request to the DHCP server; the DHCP server is used for responding to the management page query request and judging whether the target client is on line or not; when the target client is online, detecting whether the host name of the target client is missing; when the host name of the target client is detected to be missing, actively acquiring the host name of the target client; feeding back the host name of the target client to the display client; and the display client is also used for displaying a client management page according to the host name of the target client. Therefore, when the host name of the DHCP client is determined to be missing, the host name of the DHCP client can be effectively improved, so that the information of the managed client management page comprises the host name, and the use friendliness is effectively improved.
It should be noted that the display client is configured to display a client management page, and the display client may be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The DHCP server may be implemented by an independent server or a server cluster composed of a plurality of servers, which is not specifically limited. The following describes, by way of specific embodiments, a client host name processing method and apparatus, a DHCP server, a client host name processing system, and a computer storage medium, respectively, provided by the embodiments of the present application.
In an embodiment, as shown in fig. 2, a client host name processing method is provided, which is described by taking the application of the method to the DHCP server in fig. 2 as an example, and includes the following steps:
s10: judging whether the target client is on line or not;
as an example, the target client refers to a DHCP client, and for a DHCP server, it may determine whether the target client is online, and if the target client is not online, no response action is performed, and it is continuously determined whether the target client is online. If the target client is online, then execution of step S20 is triggered.
It should be noted that, in some embodiments, the step S10 is triggered when a management page display request of the display client is received. It can be understood that, when a user needs to check a management page through a display client, the display request of the management page can be triggered through the display client, and for the DHCP server, because the display client management page needs to acquire the host name of the online target client, when the display request of the management page of the display client is received, it is determined whether the target client is online. S20: when the target client is online, detecting whether the host name of the target client is missing;
s30: and when detecting that the host name of the target client is missing, actively acquiring the host name of the target client for use when displaying a client management page.
In steps S20-230, when it is detected that the target client is online, the client information of the target client, including the host name of the target client, needs to be displayed in the client management page, and therefore, in order to complete the client information, it is necessary to detect whether the host name of the target client is missing. When the host name of the target client is not lost, the host name of the target client can be acquired from the DHCP server by the display client, and then the operation is finished; therefore, in this embodiment, when detecting that the host name of the target client is missing, the step S30 is triggered, that is, the host name of the target client is actively acquired, so as to be used when displaying the client management page.
According to the embodiment, the client host name processing method is provided, when the host name of the online target client is missing, the host name of the target client can be actively acquired, so that the problem of the missing of the host name is solved, the client information is perfected, the subsequent display client can normally acquire the host name from the DHCP server, the use friendliness is improved, and the use experience of a user is improved.
In an embodiment, as shown in fig. 2, the step S10, that is, the step of determining whether the target client is online specifically includes the following steps:
s11: acquiring the IP address of the target client, and acquiring an Address Resolution Protocol (ARP) table, wherein the ARP table comprises the IP address of the online client;
s12: judging whether the IP address of the target client is in the ARP table or not;
s13: when the IP address of the target client is in the ARP table, the IP address of the client is taken out to carry out an arping operation, and if the ping is successful, the target client is judged to be online;
s14: and when the IP address of the target client is not in the ARP table or the arping operation ping is not on, judging that the target client is not on-line.
In steps S13-S14, an Address Resolution Protocol (ARP) table corresponding to the DHCP server is obtained, and an IP Address of the target client is obtained, it is understood that, in a TCP/IP network environment, each networked DHCP client is assigned an IP Address, and the IP Address is a logical Address identifying a host in the internet range. The ARP table contains the IP address and the MAC address of the online client, so that whether the target client is online or not can be judged by comparing the IP address of the target client with the IP address in the ARP table. When the IP address of the target client is in the ARP table, the IP address of the client is taken out to carry out an arping operation, and if the ping is successful, the target client is judged to be online; and when the IP address of the target client is not in the ARP table or the arping operation ping is not on, judging that the target client is not on-line.
Specifically, the target client refers to all online clients, and in this case, the ARP table may be directly obtained, all online clients are resolved from the ARP table, and then the online clients are used as the target clients, which is not limited specifically.
In this embodiment, a manner of determining whether the target client is online is provided, and specifically, the online client is analyzed by analyzing the ARP table of the DHCP server, so that the scheme has implementability and integrity.
In an embodiment, in step S20, that is, detecting whether the host name of the target client is missing, specifically, since the host name of the DHCP client is cached in a DHCP cache table (DHCP. leases) of the DHCP server, the step S20 may be implemented by determining whether the DHCP cache table of the DHCP server is cleared, or determining whether the DHCP cache table of the DHCP server is missing, and specifically, the step S20 may include the following steps:
s21: judging whether a DHCP cache table of the DHCP server is obtained or not;
s22: when the DHCP cache table is not acquired, judging that the host name of the target client side is lost;
in steps S21-S22, the DHCP server tries to acquire its own DHCP cache table first, if the DHCP cache table cannot be acquired, the DHCP cache table may be missing due to some reasons, and because the DHCP cache table is missing, the host name of the DHCP client is also naturally lost, and therefore, when the DHCP cache table is not acquired, it is determined that the host name of the target client is missing.
S23: when the DHCP cache table is obtained, judging whether a host command of the target client exists in the DHCP cache table;
s24: when the host name of the target client side is not in the DHCP cache table, judging that the host name of the target client side is lost;
s25: and when the host name of the target client side is in the DHCP cache table, judging that the host name of the target client side is not missing.
In steps S23-S25, when the DHCP cache table is obtained, it is further determined whether the host name of the target client exists in the DHCP cache table, and when the host name of the target client does not exist in the DHCP cache table, it is determined that the host name of the target client is missing, otherwise, when the host name of the target client exists in the DHCP cache table, it is determined that the host name of the target client is not missing.
Therefore, in this embodiment, a specific way of determining whether the host name of the target client is missing is provided, so that the scheme has implementability.
It should be noted that, in step S30, the host name of the target client is actively obtained, and various implementation manners are specifically provided in this application to increase the solution adaptability, which is described below separately.
In an embodiment, in the step S30, that is, actively acquiring the host name of the target client, the method may specifically include the following steps:
s31 a: acquiring an address record of a DHCP server corresponding to the target client, wherein the address record comprises a corresponding relation between an IP address of the client under the DHCP server and a host name;
s32 a: inquiring the host name corresponding to the target client from the address record of the DHCP server through the IP address of the target client
In steps S31a-S32a, the method is one of the methods for actively obtaining the host name of the target client, in which an Address record (Address record, also called a record) of the DHCP server is obtained first, where the Address record includes a correspondence between an IP Address of the client under the DHCP server and the host name, and then the host name corresponding to the target client is queried from the Address record of the DHCP server through the IP Address of the target client. As mentioned above, the IP address of the target client can be directly obtained by analyzing the ARP table. Specifically, in a specific implementation, the DHCP server may obtain the host name of the target client in a reverse direction through the IP (xxx. xxx) of the target client by using a dig command "dig-x xxx.xxx.xxx.xxx.xxx.xxx + short". The dig command can be generated by a dig tool, wherein the dig tool is a query tool for querying related information including a record and the like in a Unix-like command line mode.
In order to achieve the purpose of obtaining the host name of the target client, the embodiment of the present application provides a manner of actively obtaining the host name of the target client, which improves the implementability of the scheme.
In an embodiment, in the step S30, that is, actively acquiring the host name of the target client, the method may specifically include the following steps:
s31 b: sending a naming service (NBNS) state request to the target client so that the target client forwards the NBNS state request to a display client and receives a host name of the target client fed back by the display client;
s32 b: and receiving the host name of the target client sent by the target client.
In steps S31b-S32b, another way to actively obtain the hostname of the target client is that the DHCP server sends a naming service (NBNS) status request to the target client. It can be understood that NBNS is a naming service of NetBIOS, is used to map a NetBIOS name to an IP address, and is a child of a NetBIOS-over-tcp (nbt) protocol family, and the NBNS implementation of Microsoft is called WINS, and taking the implementation of the NBNS implementation of Microsoft as an example, a DHCP client such as a router may obtain an equipment name by sending an NBNS state request, and display that the client (e.g., windows pc client) receives the equipment name and sends the host name of the DHCP client to the DHCP client through WINS or a local cache, and then the DHCP client feeds back the host name to the DHCP server.
In the embodiment, the characteristics of the NBNS are skillfully utilized, and the DHCP server sends the naming service NBNS state request to the target client to finally acquire the host name acquired by the target client through the NBNS, so that another processing mode is improved, and the diversity and the flexibility of the scheme are improved.
In an embodiment, in the step S30, that is, actively acquiring the host name of the target client, the method may specifically include the following steps:
s31 c: sending a negative response NAK message to the target client so that the target client responds to the NAK message to disconnect the current connection and reinitiate a DHCP request to the DHCP server;
s32 c: responding the DHCP request to update a DHCP cache table of the DHCP server;
s33 c: and acquiring the host name of the target client from the updated DHCP cache table.
In steps S31c-S33c, the present invention is another way of actively obtaining the host name of a target client, in which a negative response NAK message is sent to the target client, so that the target client responds to the NAK message to disconnect the current connection and re-initiate a DHCP request to the DHCP server; in this embodiment, the above characteristics are used ingeniously to send a negative response NAK message to the target client, so that the target client responds to the NAK message to disconnect the current connection and reinitiate a DHCP request to the DHCP server, and thus, the DHCP request is responded to update the DHCP cache table of the DHCP server, and thus, the updated DHCP cache table can recover the state before the host name is lost, so that the host name of the target client can be obtained from the updated DHCP cache table.
In the embodiment, the characteristics of the NAK message are skillfully utilized, the DHCP cache table is finally and actively updated, the host name acquired by the target client through the NBNS is acquired, another processing mode is improved, and the diversity and flexibility of the scheme are improved.
In one embodiment, as shown in fig. 1, there is provided a client hostname processing system including a DHCP server and a display client, wherein:
the display client is used for sending a client management page query request to the DHCP server;
