很多人都知道端口到进程映射的一个免费工具FoundStone的Fport，可惜他不提供源码，我试着能从其二进制文件中找出一些信息，大致知道他使用了些未公开函数，诸如： ZwOpenSection，ZwQuerySystemInformation... -Many people are aware of the process to port a free map of Fport FoundStone tool, but he does not provide source code, I tried from its binary documents to find some information, he is generally aware of the use of some functions not open to the public, such as : ZwOpenSection, ZwQuerySystemInformation ...

Linux的伙伴算法把所有的空闲页面分为10个块组，每组中块的大小是2的幂次方个页面，例如，第0组中块的大小都为20 （1个页面），第1组中块的大小为都为21（2个页面），第9组中块的大小都为29（512个页面）。也就是说，每一组中块的大小是相同的，且这同样大小的块形成一个链表-Linux partners algorithm all the free page is divided into 10 blocks of groups, each group in the block size is two power-of-pages, for example, the first group in the 0 block size is 20 (one page), the first a block size of the group are 21 (2 pages), 9 blocks the size of the group are 29 (512 pages). In other words, each group in the block size is the same, and the same size to form a linked list of blocks

Linux环境下Socket编程： 1.网络时间服务器timeserver，为网络上的用户提供时间服务，即为网络用户返回服务器的当前时间；记录发出请求的网络用户的IP地址（保存到文件中），格式如下： IP地址 请求时间 时间服务客户端timeclient，该客户端能够向服务器发送时间服务请求，并把获得的时间返回给用户。 采用TCP协议编写一个远程数据备份服务器，运行客户端将本地文件备份到远程的服务器中。 -Socket Programming Linux environment: 1. Network Time server timeserver, users on the network time service, namely, Internet users to return the server" s current time record request the user" s IP network address (saved to a file), format are as follows: IP address of a request for the time spent by service clients timeclient, the client can send to the server time to service requests, and to get the time to return to the user. TCP protocol used to prepare a remote data backup server, run the client local file backup to a remote server.
