Abstract: A server management system disposes two wave generators on a rack and disposes a wave sensor on a server, wherein each of the wave generators is capable of emitting an omni-directional wave and a directional wave. When the wave sensor senses the omni-directional wave and the directional wave at different time points, one of the server and a host device is capable of determining two angles of the wave sensor relative to the two wave generators according to time differences and then calculating a position of the server located in the rack according to the two angles.

Abstract: A computer system and a remote control method thereof are provided. The method is adapted for the computer system having a network and a processor. In the method, the network card is used to receive a management interface request sent by a remote device thorough a network and send a system management interrupt to the processor, so as to wake up the processor and control the processor to enter a system management mode. Then, the processor loads a management monitoring program into a memory so as to execute the management monitor program. Finally, the processor processes the management interface request by using the management monitoring program in the system management mode, and replies a processing result to the remote device through the network by using the network card.

Abstract: A hybrid data transmission method includes broadcasting a request via a first channel from a first host device, wherein the request comprises Internet protocol (IP) address information; replying to the request with a hardware address and a bus identity of a second host device via the first channel according to the IP address information when the second host device receives the request; transmitting the hardware address and the bus identity to a second interface controller when a first interface controller receives the hardware address and the bus identity; setting a second channel according to the hardware address and the bus identity when the second interface controller receives the hardware address and the bus identity; and transmitting a plurality of data packets between the first host device and the second host device via the second channel.

Abstract: A communication method of virtual machines and a server-end system are provided. A virtual hardware address is assigned to a virtual machine when the virtual machine are established, wherein the virtual hardware address includes a tenant identity. A validation procedure for a packet is performed when the virtual machine desires to communicate with another virtual machine by transmitting the packet, so as to determine whether the virtual hardware addresses of the source-end and the destination-end in the packet have the same tenant identity. If the both virtual hardware addresses have the same tenant identity, the packet is transmitted to the another virtual machine.

Abstract: A method of operating system (OS) deployment for installing an OS on a plurality of electronic devices includes installing the OS on a sample electronic device; packing the OS in the sample electronic device into a prebuilt package; transmitting the prebuilt package to the plurality of electronic devices; and restoring the prebuilt package to the OS respectively in the plurality of electronic devices.

Abstract: A peer-to-peer based message transmitting method for a network system includes a plurality of clients and a management device. The method includes receiving a first message by the management device; adding information to the first message which is related to a plurality of target clients corresponding to the first message by the management device, in order to generate a second message; and transmitting the second message to the plurality of target clients by the management device.

Abstract: A wireless network client-authentication system and a wireless network connection method thereof are disclosed. The wireless network client-authentication system includes a network service system, a wireless router, and an electronic device. The network service system has an administrator interface module for managing a client list. The wireless router is used for uploading connection information to the network service system. The electronic device is capable of transmitting a signal via a first communication path and a second communication path. A connection module of the electronic device is used for logging in the network service system via the first communication path by a user account. The administrator interface module determines whether the user account is corresponding to the client list. If yes, the administrator interface allows the connection module to connect to the wireless router via the second communication path with the connection information.
