Abstract:
본 발명은 리눅스 데스크탑에서 USB 장치를 사용하는 경우 USB 장치에 대한 응용을 효율적으로 관리하도록 하는 장치 및 방법에 관한 것이다. 본 발명은 리눅스 커널에서 전달되는 유에스비(USB) 장치에 대한 USB 이벤트를 실시간으로 인지하고 상기 USB 이벤트를 분석하여 상기 USB 이벤트의 분석결과를 사용자 인터페이스를 통하여 사용자에게 실시간으로 알리며, 상기 USB 이벤트가 USB 접속에 따른 파일시스템 마운트 이벤트인 경우 파일시스템 마운트의 디렉토리를 출력하고, USB 장치 접속시 상기 USB 장치가 필요로 하는 장치 드라이버가 설치되었는지를 판단하여, 미설치 되었으면 장치 드라이버 서버에 접속하여 상기 장치 드라이버를 자동으로 원격 설치한다. 리눅스, 데스크탑, 실시간 알림, USB 장치, 원격 설치
Abstract:
A high-availability cluster system having a hierarchical multi-backup structure and a method for implementing high availability using the same are provided to offer an efficient availability by improving low availability and long error recovery time. A high-availability cluster system having a hierarchical multi-backup structure comprises a main node(100), a sub node(200), and backup nodes(300-1-300-N). The main node, as an active node, provides services to the nodes of a configured client membership, and outputs its own operation state information. The sub node, the backup node of the main node, receives and outputs a service provided from the main node, monitors whether a fault is generated from the main node, and outputs its own operation state information. Each of the backup nodes receives a service which is outputted through the sub node from the main node, and monitors whether a fault is generated from the sub node.
Abstract:
A method and a device for managing application of a USB device in a Linux desktop are provided to inform a user of connection/disconnection information of the USB device if a USB event occurs in the Linux desktop, and output directory content to the user in real-time when a file system according to connection of the USB device is mounted to the Linux desktop. A USB event analyzer(120) recognizes and analyzes a USB event of the USB device received from a Linux kernel. An informer(140) informs the user(10) of a USB event analysis result in real-time through a user interface(150). A USB device information processor(130) obtains USB device information according to the USB event and updates an entry for the USB device information in a device information list. The informer informs the user of entry information updated in the device information list. The USB device information processor adds the entry for the USB device to the device information list when the USB device is connected and removes the USB device entry from the device information list when the USB device is disconnected.
