Course Introduction:The USG6000 series firewall I use, the situation overview: 1. The internal network address business of accessing the server from the internal network address is normal 2. The public network address business mapped by the external network access server is normal 3. The solution to the exception of the public network address business of the internal network address access server : 1. Whether the firewall server mapping policy is written properly. Do not join the security domain. 2. UNtrust in the security policy -> trust whether to allow access to the server address 3. In the NAT policy, source NAT adds trust to the trust zone to allow normal access to the server address. I failed in the third item, so it caused the intranet The public network address mapped by the address access server is abnormal. Attached is a picture

Course Introduction:When implementing Linux system migration, special attention needs to be paid to address-related matters. The following is a summary of relevant views: 1. The importance of address mapping In the process of Linux system transplantation, accurate address mapping plays a decisive role. It determines how the operating system accesses and controls the flow of data in memory. 2. Physical address and virtual address During the Linux transplantation process, there is a mapping relationship between physical address and virtual address. The physical address refers to the actual memory address of the hardware facility; correspondingly, do you need to pay attention to the address when transplanting Linux? Linux windows, the virtual address is the logical addressing method introduced by the operating system for applications. 3. Kernel space and user space In the Linux environment, we divide the computer into

Course Introduction:Network mapping refers to network port mapping, that is, mapping a port of the IP address of an external host to a computer in the intranet to provide corresponding services. When a user accesses this port of the IP, the server will automatically map the request to the computer in the corresponding LAN. .

Course Introduction:There are three mapping methods: fully associative, direct and group associative. Direct mapping can store a main memory block into a unique Cache line; fully associative mapping can store a main memory block into any Cache line; group associative mapping can store a main memory block into a unique Cache group. any line in it.

Course Introduction:1. Definition of file mapping File mapping is a mechanism that maps files on disk to the virtual memory space of a process. In this way, the process can read and write files directly through the memory address without having to go through regular system calls such as read and write. In file mapping, we use the Linux mechanism to connect the file and the virtual memory of the process, so that the process can directly read and write file data in the memory without directly accessing the disk. This mechanism provides a more efficient file access method and also simplifies the file operation process. File mapping is often referred to as memory mapping, and the two are often the same. Memory mapping covers the operation of mapping files into memory and mapping anonymous memory into the process address space. File mapping is memory mapping
