Detailed explanation of route command parameters, adding and deleting route commands in linux The route command of linux system is used to display and operate the IP routing table (show / manage the IP routing table). To realize the communication between two different subnets, a router connecting the two networks or a gateway located in both n ...

H" Directory of header file: [build/ns3] Common header files are as follows: #include "ns3/core-module.h" // The core functions of ns-3 (such as simulating events and event scheduling) ar ...

Discovery host refers to the host that detects activity in the network. Discovering hosts is the first and most important step in implementing penetration testing. Penetration testing can only be performed further if the target host is determined to be active. Hosts can be discovered in Nmap s in different ways, such as IP discovery, ICMP d ...

Full convolution network (FCN) practice: using FCN to realize semantic segmentation FCN classifies images at pixel level, which solves the problem of semantic segmentation. Unlike the classical CNN, which uses the full connection layer to obtain a fixed length feature vector for classification after the convolution layer (full connection layer ...

Today we will use the famous pipe mkfifo to realize a simple version of QQ dialogue function. Step 1: first create two processes Talka C and talkb c； Step 2: talk a C and talkb C is responsible for checking whether two pipelines have been created. If not, it is necessary to create pipelines; Step 3: talk a C open pipe 1 in a write only mann ...

Implementation of process scheduling algorithm Summary: The process scheduling algorithm is realized, including FCFS (first in first out), SPF (short process priority), HRRF (highest response ratio priority method) and HPF (priority method). A process management simulation system that allows n processes to run concurrently is designed. The syst ...
