for network maintenance and intruders. Tcpdump exists in the basic FreeBSD system, because it needs to set the network interface to promiscuous mode, the normal user cannot execute normally, but the user with root permission can directly execute it to obtain the information on the network. Therefore, the existence of network analysis tools in the system is not a threat to native security, but a threat to the security of other computers on the network.Basically the total output format of tcpdump

Convex Hull (Only for Convex packets in two-dimensional planes) I. Definition Simply put, there is a set of N points in a two-dimensional plane S. Now you need to select a point set C, and the points in C form a convex polygon G, so that all points in the s set are either within g or on g, and the area of the convex polygon is minimized. What we need is the C set. Ii. Algorithms There are many algorithms for finding convex packets. There are two common algorithms: 1. Graham scanning method. The

Label: style blog HTTP color Io OS AR for SP Question: There are N points on the plane. Find a straight line so that all points are on the same side of the straight line. And find the minimum value of the distance between these points and the straight line. Analysis: As long as the straight line does not pass through the convex hull, the first condition is met. To minimize the distance and distance, the straight line must be on the side of the convex hull. After finding the convex hull, enumerat
