<p>[Problems] To provide a network device, a data relaying method and a program, which can be disposed without influencing a network and which extracts predetermined information such as a specific pattern from the information to flow in the network, thereby to process the extracted information and feed it again to the network, to discard the extracted information, or to inform a predetermined address of that information. [Means for Solving the Problems] A packet of a target application is specified and buffered to check its contents. When the packet containing predetermined information such as a specific pattern is detected, that information is discarded or processed and is returned to the network, thereby to inform it to a registered address by a mail or other means that the predetermined information has been received. A lamp or a warning device is started to inform a predetermined line of the received contents. The contents are checked by two kinds of methods of a real time check and a check after the packet assembly.</p> |
