If the tcpd wrapper is used, it tries to do a reverse lookup for logging the event. e.g. # ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd Try removing /usr/sbin/tcpd - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
