UDPDUMP(1)                                                          UDPDUMP(1)

NAME
       udpdump - Provide a UDP receiver that gets packets from network devices
       (like Aruba routers) and exports them in PCAP format.

SYNOPSIS
       udpdump [ --help ] [ --version ] [ --extcap-interfaces ]
       [ --extcap-dlts ] [ --extcap-interface=<interface> ]
       [ --extcap-config ] [ --capture ] [ --fifo=<path to file or pipe> ]
       [ --port=<port> ] [ --payload=<type> ]

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

OPTIONS
       --help

           Print program arguments.

       --version

           Print program version.

       --extcap-interfaces

           List available interfaces.

       --extcap-interface=<interface>

           Use specified interfaces.

       --extcap-dlts

           List DLTs of specified interface.

       --extcap-config

           List configuration options of specified interface.

       --capture

           Start capturing from specified interface save saved it in place
           specified by --fifo.

       --fifo=<path to file or pipe>

           Save captured packet to file or send it through pipe.

       --port=<port>

           Set the listener port. Port 5555 is the default.

       --payload=<type>

           Set the payload of the exported PDU. Default: data.

EXAMPLES
       To see program arguments:

           udpdump --help

       To see program version:

           udpdump --version

       To see interfaces:

           udpdump --extcap-interfaces

       Example output

           interface {value=udpdump}{display=UDP Listener remote capture}

       To see interface DLTs:

           udpdump --extcap-interface=udpdump --extcap-dlts

       Example output

           dlt {number=252}{name=udpdump}{display=Exported PDUs}

       To see interface configuration options:

           udpdump --extcap-interface=udpdump --extcap-config

       Example output

           arg {number=0}{call=--port}{display=Listen port}{type=unsigned}{range=1,65535}{default=5555}{tooltip=The port the receiver listens on}

       To capture:

           udpdump --extcap-interface=randpkt --fifo=/tmp/randpkt.pcapng --capture

           Note
           To stop capturing CTRL+C/kill/terminate the application.
