This seems okay to me.
OpenSSH uses:
struct request_info req;
request_init(&req, RQ_DAEMON, __progname, RQ_FILE, sock_in, 0);
fromhost(&req);
if (!hosts_access(&req)) {
debug("Connection refused by tcp wrapper");
refuse(&req);
/* NOTREACHED */
fatal("libwrap refuse returns");
}
I take it that newsockfd is the one returned from accept()?
I'd try using a debug version of libwrap...
