This needs to be a sockaddr_in too.

addrlen = sizeof(struct sockaddr_in);
rc = accept(msgSock, (struct sockaddr *)&client, &addrlen);

You can use inet_ntoa(client.sin_addr) in this case, since you've just
called accept(2). In the more general case, use getpeername(2) on the
connected socket. Use gethostbyaddr(3) to convert that into a name.
