Berkeley sockets is an application programming interface (API) for Internet sockets and Unix domain sockets, used for inter-process communication (IPC). It is commonly implemented as a library of linkable modules.

UDP sockets. UDP or user datagram protocol is an alternative protocol to its more common counterpart TCP. UDP like TCP is a protocol for packet transfer from 1 host to another, but has some important differences. UDP is a connectionless and non-stream oriented protocol. If it uses the TCP protocol to send and receive the data then it will connect and bind itself to a TCP port. If it uses the UDP protocol to send and receive data, it will use a UDP port. Figure 1 Sep 20, 2018 · In later versions (9.9.6 and 9.10.0) we reduced the default number of UDP listeners per interface from equaling the number of worker threads, to half of that value. The default setting for the -U option (setting the number of UDP listeners per interface) has been adjusted to improve performance. [RT #35417] The TCP & UDP Bindings act as a network client or as a network server. # Binding Configuration. The TCP and UDP bindings can be configured in the files services/tcp.cfg and services/udp.cfg, respectively. Note that the parameters set in these files will be common for all the TCP connections of this binding, both client and server connections. Berkeley sockets is an application programming interface (API) for Internet sockets and Unix domain sockets, used for inter-process communication (IPC). It is commonly implemented as a library of linkable modules. With UDP, you have to bind() the socket in the client because UDP is connectionless, so there is no other way for the stack to know which program to deliver datagrams to for a particular port. If you could recvfrom() without bind() , you'd essentially be asking the stack to give your program all UDP datagrams sent to that computer.

Dan Thank you for your attention to this matter. I must say I had seen the bind option and it dis occur to me to try it. I just had not yet when I googled if someone else had the problem. I was mostly concerned with the udp settings, most of my testing and usage is tcp. I see the same problem in many softwares.

UDP makes use of Internet Protocol of the TCP/IP suit. In communications using UDP, a client program sends a message packet to a destination server wherein the destination server also runs on UDP. bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr . Traditionally, this operation is called "assigning a name to a socket".
