Description of problem:

audisp-remote does
>		memset (&address, 0, sizeof(address));
>		address.sin_family = htons(AF_INET);
>		address.sin_port = htons(config.local_port);
>		address.sin_addr.s_addr = htonl(INADDR_ANY);
which shows in strace as

> bind(3, {sa_family=0x200 /* AF_??? */, sa_data="\0<\0\0\0\0\0\0\0\0\0\0\0\0"}, 16) = 0

For some reason the call still succeeds, but a correct invocation would not call htons on AF_INET.
