The main goal of the Sniffer tool is to discover the surviving hosts in the target network based on UDP, because the UDP access process is less expensive.Since many operating systems have a common denominator when dealing with the closure of UDP ports, we are using this commonality to determine if there are surviving hosts on this IP.When we send a packet to a UD

exchange environment must be in and out of the gateway, so in the above example, host a is changed to the gateway, hackers are deceiving the communication between the target host and the gateway. When this arp error ing table persists, the data packets from the gateway to the target host and the data packets from the target host must pass through the server that initiates the spoofing. The sniffing tool is described above, hackers use a packet captur

These tools monitor and manage the network at the lowest level, as well as the most granular monitoring, at the expense of the process of affecting network I/O and analysis. dhcpdump: A command-line DHCP traffic sniffing tool that captures DHCP request/reply traffic and displays decoded DHCP protocol messag

highly recommended web-based PNG image compression optimizer that uses an intelligent lossy compression technique that reduces the size of a PNG image by reducing the number of colors in the image to reduce the amount of data needed to store the image. This compression has a small effect on the effect of the picture, but it can greatly reduce the size of the image and also preserves the alpha transparency of the PNG. At some point the tinypng compression rate is very gratifying, and basically d

After the client receives a "challenge", it decrypts it with its own private key and sends it to the server. The second level does not require a password to be sent over the network compared to the first level.PS: Simply put, the client's public key is placed on the server, then the client can password-
