hping 是一个运行在Linux,FreeBSD,NetBSD, OpenBSD, Solaris, MacOs X 命令行方式下的TCP/IP包分析器。它类似于unix命令下的ping命令，但是hping它不能发送ICMP响应请求。它支持TCP, UDP, ICMP和RAW-IP 协议。它可以运行在跟踪模式，在一个隐蔽的通道内发送文件等各种功能。-hping is a run on Linux, FreeBSD, NetBSD and OpenBSD, Solaris, MacOs X command line under the TCP/IP packet analyzer. Unix command similar to the ping command, but hping it could not send ICMP response to the request. It supports TCP, UDP, ICMP and RAW-IP protocol. It can run in tracking mode, in a hidden passage within this document and other functions.

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
