![]() ![]() Instead of your current data you should send like this for having a valid datagram:Įthernet Headers w/ IPv4 (14Byte): (as in your implementation, but type IPv4 0x0800), Source, Dest, Type 64006a493488 020826283900 0800 It does show a strange TTL with a value of 0, but that may be sender related. The packet seems not to be a valid UDP Datagram.Īfter fiddling with the packet it seem to be enough to change the type in the ethernet header to to IPv4 (0x0800). The IP packets of the incoming packets have a correct checksum that is NOT being set to 0x0000. ![]() The ARP transmission and reply can be found as the 5th, 10th, and 11th packet. ![]() The IP header has the Source IP as 192.168.10.200 and the Destination IP as 192.168.10.10, UDP Header has Source Port as 1920 and Destination Port as 1919.Īs you can see, the packet is repeated and sent from the FPGA at 2KHz. The Ethernet Header shows a correct Destination (my MAC address), Source Address (hard coded in the FPGA), and Length. Wireshark has the 2KHz packets as LLC packets. Why is Wireshark able to see these messages, but my program is not? #What is wireshark qt how to#
