daytime服务，这个源码说明文档写的很详细，对linux下系统函数作了一点归纳。希望对你有所帮助。...

* A ncurses user interface. * Network statistics to view the amount of packets and data in many different protocols, interfaces and hosts. * View what active TCP connections are on the network. * View UDP packets. * View and log ICMP packets. * View and log the 48bit arp protocol. And also view what make of network card is in each machine * Multithreaded so that the user interface does not interfere with any of the packet captureing methods. * View and log the following user space protocols FTP, POP3, HTTP-* A ncurses user interface. * Network statistics to view the amount of packets and data in many different protocols, interfaces and hosts. * View what active TCP connections are on the network. * View UDP packets. * View and log ICMP packets. * View and log the 48bit arp protocol.
