Hi!

	NetBSD returns an error when binding an UDP address where
the host address matchs a local iface (instead of the more used
INADDR_ANY). I'm not familar with the networking code,
and I'm not sure if this is a bug or a feature... Could somebody
tell me, so that I send-pr it if it is a bug?

PS: Next, the code which causes EADDRNOTAVAIL. I think it should just
work. Was tested on NetBSD-1.1/i386 and NetBSD-1.2/i386.

#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <stdio.h>

main()
{
  int sock, length;
  struct sockaddr_in name;
  char buf[1024];

  /* Create socket from which to read. */
  sock = socket(AF_INET, SOCK_DGRAM, 0);
  if (sock < 0) {
    perror("opening datagram socket");
    exit(1);
  }
  /* Create name with wildcards. */
  name.sin_family = AF_INET;
  name.sin_addr.s_addr = inet_addr("163.117.137.172"); /* Here your addr */
  name.sin_port = 0;
  if (bind(sock, (struct sockaddr *) &name, sizeof(name))) {
    perror("binding datagram socket");
    exit(1);
  }
  /* Find assigned port value and print it out. */
  length = sizeof(name);
  if (getsockname(sock, (struct sockaddr *) &name, &length)) {
    perror("getting socket name");
    exit(1);
  }
  close(sock);
}
