29 *udpdump* is a extcap tool that provides a UDP receiver that listens for exported datagrams coming from
30 any source (like Aruba routers) and exports them in PCAP format. This provides the user two basic
31 functionalities: the first one is to have a listener that prevents the localhost to send back an ICMP
32 port-unreachable packet. The second one is to strip out the lower layers (layer 2, IP, UDP) that are useless
33 (are used just as export vector). The format of the exported datagrams are EXPORTED_PDU, as specified in
34 https://gitlab.com/wireshark/wireshark/-/raw/master/epan/exported_pdu.h

42 Print program version.
45 List available interfaces.
47 --extcap-interface=<interface>::
48 Use specified interfaces.
51 List DLTs of specified interface.
54 List configuration options of specified interface.
57 Start capturing from specified interface save saved it in place specified by --fifo.
59 --fifo=<path to file or pipe>::
60 Save captured packet to file or send it through pipe.
63 Set the listener port. Port 5555 is the default.
66 Set the payload of the exported PDU. Default: data.
