Description
Technical Field
The invention relates to the technical field of Linux server connection, in particular to a method and a system for remotely connecting a Linux server.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
At present, when a user logs in a Linux server, the user needs to install a ssh client program, and when the user wants to hang up and run a foreground program, the user needs to use third-party tool software to realize the ssh client program. Therefore, when the user runs the application program on-hook, the user needs to run other application programs independently, and the user cannot directly carry out on-hook operation on the current window, which is very inconvenient.
When a user wants to connect to the Linux server host of IPv6, since most of the current lans do not support the IPv6 network, the user can only access a lan with an IPv6 address, or use the tunnel proxy tool from IPv4 to IPv6 to connect to the Linux server in the IPv6 segment, which increases the complexity of the user.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a method and a system for remotely connecting a Linux server; the problem that a user is complex in on-hook operation, and only a host with an IPv4 network address cannot access a host with an IPv6 network segment is solved; the method is convenient to use, and simultaneously supports the login and the on-hook of the Linux server of the IPv4 and the v6 address protocols.
In a first aspect, the present invention provides a method for remotely connecting to a Linux server;
a method of remotely connecting to a Linux server, comprising:
a login server receives a first login request sent by a client;
the login server sends an identity authentication request to the authentication server;

the login server receives a Linux server selection request sent by a client;
the login server forwards the Linux server selection request to the authentication server;
the authentication server verifies the client, and returns a verification result to the login server;
the login server executes corresponding operation according to the state information in the return parameters; when the state information is true, the Linux server returns a login authentication result to the login server;
and the login server directly returns the information received from the Linux server to the client.
In a second aspect, the invention provides a system for remotely connecting a Linux server;
a system for remotely connecting a Linux server, comprising: a plurality of clients; each client is connected with a plurality of login servers, and each client is connected with an authentication server; each login server is connected with a plurality of Linux servers, and the Linux servers are servers supporting IPv4 and IPv6 address protocols;
the method comprises the following steps that a login server receives a first login request sent by a client;
the login server sends an identity authentication request to the authentication server;
the authentication server verifies whether the account information of the user requesting login is correct or not according to the account information pre-stored in the database, and if the account information is correct, the authentication server sends the resource information of the user to the client;
the login server receives a Linux server selection request sent by a client;
the login server forwards the Linux server selection request to the authentication server;
the authentication server verifies the client, and returns a verification result to the login server;
the login server executes corresponding operation according to the state information in the return parameters; when the state information is true, the Linux server returns a login authentication result to the login server;
and the login server directly returns the information received from the Linux server to the client.
Compared with the prior art, the invention has the beneficial effects that:
as long as the login server can support IPv4 and IPv6 networks, even if only one client exists, the login server can communicate with user resources of IPv4 or IPv6 network segments without changing the network environment of the client. In the using process of the client, if a network problem or a human misoperation occurs, and the client is disconnected from the login server, the login server will put the link into an on-hook pool of the login server and keep a certain connection duration, and when the user connects the device again within the connection duration, the last operation can be continued, for example: unedited documents, unexecuted programs, etc. The implementation mode not only reduces the loss of server resources, but also solves the problem of operation loss caused by accidental exit of long connection.
