NTOP包装说明
NTOP是一个工具,显示网络使用情况,类似于流行的顶级Unix命令一样。 NTOP基于pcapture(ftp://ftp.ee.lbl.gov/pcapture.tar.Z),它已被写入在便携式方式以几乎所有的Unix平台上运行。 NTOP可以在两个交互式或web模式下使用。在第一种情况下,NTOP显示而在网络模式下的Web浏览器(如Netscape),即可连接到NTOP(充当Web服务器),并获取网络状态转储到用户终端上的网络状况。在后一种情况下,NTOP可以被看作是一个简单远程监控类试剂具有嵌入式Web界面。 NTOP使用libpcap的,对于用户级数据包捕获系统无关的接口。 资料来源:NTOP自述
