Network Address Translation  来源:http://alexanderlaw.blog.hexun.com/9791596_d.html       地址转换用来改变源/目的地址/端口,是netfilter的一部分,也是通过hook点上注册相应的结构来工作       Nat注册的hook点和conntrack相同,只是优先级不同,数据包进入netfilter之后先经过conntrack,再经过nat.而在数据包离开netfilter之前先经过nat,再经过conntr…

一.概述 NAT英文全称是“Network Address Translation”,中文意思是“网络地址转换”,它是一个IETF(Internet Engineering Task Force, Internet工程任务组)标准,允许一个 整体机构以一个公用IP(Internet Protocol)地址出现在Internet上.顾名思义,它是一种把内部私有网络地址(IP地址)翻译成合法网络IP地址的技术.NAT 可以让那 些使用私有地址的内部网络连接到Internet或其它IP网络上.NAT路…

当封包流经NAT電腦時,其位址/通訊端口會被修改,以達到改变包目的地(或旅程),或是让目的地误以为包是源自NAT电脑的效果.換言之,对封包执行NAT的电脑,可以成为新包的来源或目的地,或是成为真正来源与目的地之间的中继站. ***************************** 警告: NAT需要连线追踪的能力,而连线追踪又需要电脑能看到所有包才有效,所以,如果你的防火墙是有多台电脑构行,请小心避免破坏连线追踪. ***************************** 利用NAT的位址/…

BACKGROUND As processing resources have increased, demands to run multiple software programs and operating systems on a single microprocessor have also increased. To meet these demands virtual environments have been developed to allocate a single com…

BACKGROUND A conventional virtual-machine monitor (VMM) typically runs on a computer and presents to other software the abstraction of one or more virtual machines. Each virtual machine may function as a self-contained platform, running its own "gues…

Embodiments of the invention are generally directed to systems, methods, and apparatuses for linear to physical address translation with support for page attributes. In some embodiments, a system receives an instruction to translate a memory pointer…
