Re: Dos Attack: TCP/UDP Chargen?! It's impossible to tell the exact origin as these were almost definitely spoofed with your IP. This could be part of a zombie scan or a misconfiguration of an attack but both of these are just background noise that you get from being on the internet.

User Datagram Protocol (UDP) provides an alternative to Transmission Control Protocol (TCP). These protocols work on top of the Internet Protocol (IP) so you may also see them listed as UDP/IP and TCP/IP. While TCP uses host-to-host communication, UDP uses process-to-process communication. UDP sends datagrams instead of individual packets. Apr 13, 2016 · Definition Of UDP UDP or User Datagram Protocol is a connectionless protocol found in the transport layer of TCP/IP Model. It neither establishes a connection nor checks whether the destination computer is ready to receive or not; it just sends the data directly. UDP is used to transfer the data at a faster rate.
If you want to block or open a certain TCP or UDP port, here is the process. Search for an open TCP or UDP port. Open the The Start menu. (For Windows 10, press the Windows button) and type CMD.
