Method and device for achieving remote access

Abstract

The invention discloses a method for achieving remote access. The method comprises the steps that a virtual keyboard, a display and a mouse (KVM) remote access request sent by a user side is acquired, wherein the remote access request carries ID information and a virtual KVM address of accessed equipment; a virtual KVM mapping address of the accessed equipment is acquired according to the ID information of the accessed equipment; the virtual KVM address of the accessed equipment is replaced with the virtual KVM mapping address; and a virtual KVM session connection between the user side and the accessed equipment is established according to the virtual KVM mapping address. The invention further discloses a device for achieving remote access.

Description

technical field [0001] The invention relates to data access technology in the field of network communication, in particular to a method and device for realizing remote access. Background technique [0002] At present, the methods for remotely accessing virtual keyboards, displays, and mice (KVM, Keyboard VideoMouse) across networks mainly include: virtual private network (VPN, Virtual Private Network) mode, routing mode and static network address translation (NAT, Network Address Translation) mode ,in; [0003] The virtual VPN method is to set up a VPN server in the network of the visited device, install a VPN client on the user end device, and the user end device dials into the VPN network of the visited device through the VPN client to realize the monitoring of the visited device. remote access to virtual KVM. [0004] The disadvantage of using the above-mentioned virtual VPN method is that the VPN client needs to be installed on the client device, and before use, the cl...

Problems solved by technology

[0004] The disadvantage of using the above-mentioned virtual VPN method is that the VPN client needs to be installed on the client device, and before use, the client device needs to dial into the VPN network of the visited device through the VPN client to realize remote access to the visited device and operate Quite complicated; after the client device dials into the VPN network of the visited device through the VPN client, not only will the routing table of the VPN client change, but the client device can also access all virtual KVMs of the visited device through the VPN client , so that it is easy to cause unauthorized access to the client device, which poses a security risk in the data center

[0006] The disadvantage of using the above routing method is: once the network route between the client device and the visited device is reachable, the network isolation between the client device and the visited device cannot be realized, and there are security risks in the data center

[0008] The disadvantage of adopting the above-mentioned static NAT method is: not only the manufacturer client of the visited device needs to be pre-installed on the client device, but also the static NAT needs to occupy a large amount of IP addresses of the client device, and the client device needs to be pre-configured. The IP address is configured, the operation is more complicated
