    Summary of Useful tcpdump Flags for UDP:
    udp: Capture all UDP traffic.
    -i <interface>: Specify the network interface to listen on.
    port <port_number>: Filter by a specific UDP port.
    host <ip_address>: Capture traffic from/to a specific IP.
    src/dst host <ip_address>: Capture UDP packets from/to a specific source/destination IP.
    -X: Show detailed packet content in hexadecimal and ASCII.
    -w <file_name>: Write captured packets to a file.
    -c <count>: Limit the number of packets captured.
    By using these commands and filters, you can effectively capture and analyze UDP traffic using tcpdump.

    ### Summary of Useful `tcpdump` Flags for UDP:

    - **`udp`**: Capture all UDP traffic.
    - **`-i <interface>`**: Specify the network interface to listen on.
    - **`port <port_number>`**: Filter by a specific UDP port.
    - **`host <ip_address>`**: Capture traffic from/to a specific IP.
    - **`src/dst host <ip_address>`**: Capture UDP packets from/to a specific source/destination IP.
