It won't always work when we bind to a wildcard. The issue lies in the sendto() line — we didn't explicitly set the outbound IP address! Linux doesn't know where we'd like to source the packet from, and it will choose a default egress IP address.

The getaddrinfo() function combines the functionality provided by the gethostbyname(3)and getservbyname(3)functions into a single interface, but unlike the latter functions, getaddrinfo() is reentrant and allows WebWhen one is raising the privileges of an executable, the runtime loader (rtld), better know as ld.so will not link with libraries in untrusted paths. This is the way the ld.so (1) has been designed. If one needs to run such an executable, then you have to add that path to the trusted paths of ld.so, the following describes how to do so:
WebThere are four types of sockets available in POSIX API: TCP, UDP, UNIX, and (optionally) RAW. Unix domain sockets may act like stream sockets or like datagram sockets. Some of endpoint types: struct sockaddr - universal endpoint type. Typically, other concrete endpoint types are converted to this type only in posix calls. Webif you bind your socket to INADDR_ANY, it'll receive every packet sent to that specific port. Sending multicast may or may not function and that depends on if you have multiple interfaces. As you mention multiple process listening, you may need setsockopt () SO_REUSEADDR .. before the bind () call. 4 dwargo • 5 yr. ago
WebDescription When a socket is created with socket (2), it exists in a name space (address family) but has no address assigned to it. 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.
