The statements in this section merely relate to the background of the present disclosure and may not necessarily constitute prior art.
Currently, when a user logs in a Linux server, the user needs to install an ssh client program, and when the user wants to hang up a foreground program to run, the client program needs to be realized by means of tool software of a third party. This makes it inconvenient for the user to run other applications separately while the user is on-hook, and the on-hook operation cannot be performed directly on the current window.
When the user wants to connect with the Linux server host of IPv6, most of the current local area networks do not support the IPv6 network, so that the user can only access to a local area network with an IPv6 address, or connect with the Linux server in the IPv6 network segment by using the tunnel proxy tool from IPv4 to IPv6, which increases the complexity of use of the user.
Disclosure of Invention
In order to solve the defects in the prior art, the invention provides a method and a system for remotely connecting a Linux server; the problem that a host computer with an IPv4 network address only cannot access an IPv6 network segment host computer due to complex user on-hook operation is solved; the Linux server login and program hanging up supporting IPv4 and v6 address protocols are convenient to use.
In a first aspect, the present invention provides a method for remotely connecting a Linux 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;
the login server directly returns the information received from the Linux server to the client.
In a second aspect, the present invention provides a system for remotely connecting to 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 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 according to the account information stored in the database in advance, and if so, 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;
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 is able to support both IPv4 and IPv6 networks, even if only one of the clients is available, it is possible to communicate with the user resources of the IPv4 or IPv6 network segment without changing its own network environment. In the use process of the client, if a network problem or a human misoperation occurs, and the client is disconnected with the login server, the login server places the link into a hanging pool of the login server, a certain connection duration is maintained, 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 way reduces the loss of server resources and solves the problem of operation loss caused by unexpected exit of long connection.
