=head1 DESCRIPTION
|
|
|
|
B<udpdump> is a extcap tool that provides an 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
