to run the client program locally and encrypt the communication with the service-side program that connects to the remote proxy server. Then the proxy port is simulated locally, so that the native traffic is encrypted by the local client and then transferred to the remote server to complete the proxy forwarding service.So we just need to buy a Linux-based VPS server, the cost of about 15 yuan per month, after the installation of a good service, you c

High-end memory refers to memory with a physical address greater than 896M. For such memory, it is not possible to map in "Kernel Direct mapping Space".Why?Because "kernel direct mapping Space" can only be from 3G to 4G, only directly mapped 1G physical memory, for more than 1G of physical memory, powerless .In fact, "kernel direct mapping Space" also does not reach 1G, but also to leave a bit of linear spa

Linux operating system and drivers run in kernel space, applications run in user space, both cannot simply use pointers to pass data, because Linux uses a virtual memory mechanism, user-space data may be swapped out, and when kernel space uses user-space pointers, The corresponding data may not be in memory. Linux Kernel address mapping modelThe x86 CPU uses a Segment-page address mapping model. The address in the process code is a logical address, and after a segment-page address mapping, the p

Linux Kernel address space partitioning Typically, the 32-bit Linux kernel virtual address space is divided into 0~3g for user space, 3~4g for kernel space (note that the kernel can use a linear address of only 1G). Note that this is a 32-bit kernel address space partition, and 64-bit kernel address space partitioning is different. Typically, the 32-bit Linux kernel virtual address space is divided into 0~3g for user space, 3~4g for kernel space (note that the kernel can use a linear address o

first, big end mode Small terminal mode The so-called "big-end mode" refers to the low data (that is, the number of lower weights) stored in the high memory address , and the high level of data, stored in the low memory address , Such a storage pattern is somewhat similar to processing data as a string order: The add

With the development of China's routing industry, it has also promoted the technical upgrade of high-end routers. Here we mainly explain the classification and content of high-end routers, A router is a device that forwards packets to achieve network interconnection. It supports multiple protocols (such as TCP/IP, SPX,

So the question is, why should Samsung enter the ultra-high-end business handset market while owning the

, checking a constant linear address is unnecessary. 3 high-end memory kernel ing We have analyzed above. In Linux memory management, the kernel uses a 3-G 4G linear address space, with a total size of 1 GB. In x86, the linear addresses of m in the kernel page table correspond to physical addresses one by one, while the remaining MB linear addresses are reserved for other users (for non-continuous memory

High-end memory refers to the memory with a physical address greater than 896 MB. For such memory, the ing cannot be performed in the "kernel direct ing space. Why?Because the "kernel direct ing space" can only be from 3G to 4g, and can only be mapped to 1g physical memory directly, there is nothing to do with physical memory larger than 1g. In fact, the "kernel direct ing space" cannot reach 1 GB, and we h

Master the high-end switch cascade to instantly become a master of the network, previously introduced the relevant knowledge. After the publication of the stack and cascade of switches, we have received a number of emails from many readers to discuss with us about the cascade of switches. So we will introduce some related content about high-

Especially in the aspect of

OverviewOn a 32-bit system, the kernel occupies a linear address space from 3gb~ 4GB, a total of 1GB size, and the kernel directly maps the 0~896MB of the former 896MB to the physical memory, i.e. the linear mapping, which takes the remaining 128M linear address space as a window to access the memory above 896M. The main reason for the introduction of high-end memory mapping is that when we install more tha

There are a lot of things worth learning about the core route switch. Here we will mainly introduce the detailed knowledge of the high-end multi-service IPv6 core route switch.
