bind failed: Cannot assign requested address

I'm trying to write a C program that listens on a port on my machine. I'm running into a strange error. Whenever I try to bind the socket to a fixed ip (either `127.0.0.1` or my actual IP) I get a `"bind failed: Cannot assign requested address"` error. However when I pass `INADDR_ANY` to the bind as the address to bind to, it works. These are the only two IPs I have so it can't be that the 0.0.0.0 works because of some other IP address I have available. Here is the code: ``` #include<sys/types.h> #include<stdio.h> #include<sys/socket.h> #include<netinet/in.h> #include<errno.h> #include<stdlib.h> #include<string.h> int main() { int port = 1234; /* port number */ int rqst; /* socket accepting the request */ socklen_t alen; /* length of address structure */ struct sockaddr_in my_addr; /* address of this service */ struct sockaddr_in client_addr; /* client's address */ int sockoptval = 1; int svc; /* create a TCP/IP socket */ if ((svc = socket(AF_INET, SOCK_STREAM, 0)) < 0) { perror("cannot create socket"); exit(1); } /* allow immediate reuse of the port */ setsockopt(svc, SOL_SOCKET, SO_REUSEADDR, &sockoptval, sizeof(int)); /* bind the socket to our source address */ memset((char*)&my_addr, 0, sizeof(my_addr)); /* 0 out the structure */ my_addr.sin_family = AF_INET; /* address family */ my_addr.sin_port = htons(port); //my_addr.sin_addr.s_addr = htonl(INADDR_ANY); /* Works! */ my_addr.sin_addr.s_addr = htonl(inet_addr("127.0.0.1")); /* Fails! */ if (bind(svc, (struct sockaddr *)&my_addr, sizeof(my_addr)) < 0) { perror("bind failed"); exit(1); } printf("Listening on %d\n", my_addr.sin_addr.s_addr); /* set the socket for listening (queue backlog of 5) */ if (listen(svc, 5) < 0) { perror("listen failed"); exit(1); } /* loop, accepting connection requests */ for (;;) { while ((rqst = accept(svc, (struct sockaddr *)&client_addr, &alen)) < 0) { /* we may break out of accept if the system call */ /* was interrupted. In this case, loop back and */ /* try again */ if ((errno != ECHILD) && (errno != ERESTART) && (errno != EINTR)) { perror("accept failed"); exit(1); } } /* the socket for this accepted connection is rqst */ } } ```
