Apr 12, 2025 pm 11:00 PMDebian Sniffer is a network sniffer tool for capturing and analyzing network packets
Timestamp: Displays the time of packet capture, usually in seconds.
Source IP address: The network address of the device that sent the packet.
Destination IP address: The network address of the device receiving the data packet.
Source Port: The port number used by the device sending the packet.
Destination Port: The port number used by the device receiving the packet.
Protocol: Network protocols used by data packets, such as TCP, UDP, ICMP, etc.
Packet Length: The total length of the packet, including the header and load.
Data: The payload of the data packet, that is, the actual data transmitted.
When interpreting the output results of Debian Sniffer, you need to pay attention to the following points:
Exceptional traffic: Check for large amounts of packets from the same source or target, which may indicate a cyber attack or abnormal behavior.
Unused ports: Check if there are a large number of packets sent to unused ports, which may indicate scanning behavior or misconfiguration.
Protocol distribution: Check the number of packets for different protocols to understand which protocols are mainly used in the network.
Packet size distribution: View the size distribution of data packets to understand the types and sizes of data transmitted in the network.
Duplicate packets: Check for duplicate packets, which may indicate network problems or attack behavior.
By analyzing this information, we can understand the normal behavior and potential problems of the network, and thus take corresponding measures to optimize and protect the network.

Windows 10 right-click menu can be managed through third-party tools, registry editing, or command line.

You need to back up the registry before operation; finally, you can use the open source tool ContextMenuManager to batch manage menu items through command line list, disable, enable and other parameters, which is suitable for advanced users.
