Under normal circumstances, we mount NTFS under Linux, is installed after the ntfs-3g, namely:
# mount-t Ntfs-3g/dev/sdb1/mnt/dataThis can be done temporarily, but it will involve permission issues, that is, all files under/mnt/data must have root permissions. So we added some parameters so that the current u
A comprehensive network planning and optimization software, which has many kinds of technology and user-friendly interface, plays an important role in the wireless network planning and design process of mobile operators. The software not only has a strong engineering capacity, but should be an open, scalable and flexible technology information system that can be easily integrated with other IT systems to increase productivity and shorten delivery latency. This paper mainly analyses the technical
