Description
Technical Field
the invention relates to the field of data communication, in particular to a Portal authentication method and access equipment.
Background
in a traditional networking environment, as long as a user can access a local area network device, the user can access a device or a resource in a network, in order to ensure the security and operation management of network information, the legality verification of the user accessing the network is generally considered when the network is deployed, and in a specific scene, the legal user needs to be charged, namely authentication, authorization and charging.
Portal authentication is also commonly referred to as Web authentication, and Portal authentication Web sites are commonly referred to as Web portals. When the unauthenticated user accesses the network, the access equipment forces the user to log in the portal website, the user can freely access the network resources in the portal website, when the user needs to access more network resources, the user needs to authenticate the portal website, and the user can access the related network resources only after the authentication is passed.
In the existing network technology, the Portal authentication mode has the advantages of reducing the maintenance workload of the client and facilitating operation because the authentication client does not need to be installed, and can develop service expansion, technical maturity and the like on a Portal page, so that the Portal authentication mode is widely applied to networks such as operators, schools and the like.
Portal authentication is usually completed by matching access equipment, a Portal server and a RADIUS (remote authentication dial in user service) server to authenticate, authorize and charge a legal user access network, but in an actual application scene, the server is generally unreachable due to various problems (such as server network abnormality and access equipment network abnormality), and the reflected result is that an authentication page has no response for a long time and cannot normally access the network, and a user cannot perceive what problem occurs in the authentication process.

Detailed Description
The invention aims to provide a Portal authentication method and access equipment, and solves the problem that a user authentication page is not reactive for a long time because the inaccessible state of a server cannot be sensed in Portal authentication in the traditional technology.
The core idea is as follows: when the Portal server or all RADIUS servers are not reachable, the access equipment port is set to be in an unreachable state, the state of the server is informed through a built-in Web interface, and the accessible specific resources are informed in combination with the configuration condition of an escape ACL (access control list), so that the specific access authority of the user is released.
the scheme of the invention is further described by combining the drawings and the embodiment:
As shown in fig. 1, the access device in this embodiment includes: the system comprises a port state judging module, a port state setting module, a state pushing module, an escape ACL configuration module and a server detection module; in particular, the method comprises the following steps of,
the port state judging module is used for judging the state of the port when receiving a Portal authentication request initiated by a user;
The port state setting module is used for setting the port state as a server unreachable state if the server unreachable is found in the normal authentication process; and the port state is changed into the reachable state of the server when the server detection module detects that the state of the server is reachable.
And the state pushing module is used for pushing the inaccessible page of the server to the user through the built-in web page when the condition that the server is in the inaccessible state is judged through the port state, and informing the user whether specific resources which can be accessed exist or not by combining the configuration condition of the escape ACL.
And the escape ACL configuration module is used for configuring an escape ACL based on a port on the access equipment, binding the escape ACL configured for the user when the port state is that the server is not reachable, and unbinding the escape ACL configured for the user when the port state is that the server is reachable.
and the server detection module is used for periodically detecting the state of the server when the port state is that the server is unreachable, and triggering the port state setting module if the port state is detected to be reachable.
based on the above access device, a flow of a Portal authentication method provided by the embodiment of the present invention is shown in fig. 2, and the method includes the following implementation steps:
s201, a user initiates a request authentication to access equipment;
s202, the access equipment judges the state of a port; the port states in this embodiment are divided into three types: namely, server reachable (Portal server reachable and at least one RADIUS server reachable), Portal server not reachable, RADIUS server not reachable;
s203, if the current server is in the reachable state, the step S206 is executed;
s204, if the current state is the inaccessible state of the Portal server, the step S209 is entered;
s205, if the RADIUS server is not reachable currently, the step S213 is executed;
S206, entering a Portal authentication process under the current server reachable state, firstly, connecting the access equipment with a Portal server for interaction, if the interaction is successful, entering a step S207, and if the Portal server is found to be unreachable, entering a step S208;
S207, entering an RADIUS authentication flow, connecting the access equipment with an RADIUS server for interaction, and entering a step S210 if the interaction is successful; if the interaction is not successful, go to step 211;
s208, when finding that the Portal server is unreachable, setting the port to be in a Portal server unreachable state, and entering the step S209;
s209, pushing an inaccessible state of a Portal server and accessible resources of a user to the user through a built-in web page of the access equipment, wherein in the step, if an escape ACL is configured for the user in the access equipment in advance, the specific resources which can be accessed by the user are informed based on the escape ACL, and the configured escape ACL is bound for the user; if the escape ACL is not configured, informing the user that no resource can be accessed;
S210, if the interaction with the RADIUS server is successful, feeding back an authentication result to the user;
S211, if the RADIUS server appointed by the user is found to be unreachable, because the users with different domain names can walk through different RADIUS servers, whether all the RADIUS servers are reachable or not needs to be judged;
s212, when all the RADIUS servers are not reachable, setting the port state as a RADIUS server unreachable state, and entering the step S213;
S213, pushing an inaccessible state of the RADIUS server and accessible resources of the user to the user through a built-in web page of the access equipment, wherein in the step, if an escape ACL is configured for the user in the access equipment in advance, the specific resources which can be accessed by the user are informed based on the escape ACL, and the configured escape ACL is bound for the user; and if the escape ACL is not configured, informing the user that no resource can be accessed.
in addition, the invention also sets a detection mechanism when the server is not reachable, so as to recover the port state in time when the server is detected to be reachable and carry out normal Portal authentication, which is concretely as follows:
when the Portal server is not reachable, a TCP connection is established at regular time to detect whether the Portal server is reachable, when the RADIUS server is not reachable, a request message is sent at regular time to detect whether the RADIUS server is reachable, and when the Portal server and any one RADIUS server which are configured with the port are detected to be in reachable states, the port is set to be in a server reachable state; and after the escape ACL of the user is unbound, redirecting the access request of the user to a normal Portal authentication flow.
