![]() ![]() In particular, if the binary value of the first two bytes following the two MAC addresses is higher than 1536 (0圆00), these whole frame is an Ethernet II one (where these two bytes contain an "ethertype", otherwise as an 802.3 frame (where these two bytes contain the length of the frame). want to express transmission direction of the hex-dumped packets by swapping the sender and recipient address in your handcrafted headers.Īs for Ethernet II and 802.3 in particular, these two can even peacefully coexist on the same wire, which means that they have to be easily discriminated from one another. These may be the same for all packets or you may e.g. If none of the available encapsulation types matches the one you need, you may use a custom encapsulation type, for which you'll have to specify the dissector through configuration, or you may prefix the packet data with a manually created bytes representing a protocol for which encapsulation exists (such as Ethernet). Of course the encapsulation type specified must match the actual contents of the packets. The list of supported encapsulation types is here. So if importing a hex dump, you must provide this information manually: in the GUI, there is a drop-down menu for that, if you use the command-line utility text2pcap, you have to use a -l n command line parameter where n is a number representing the encapsulation type. The pcap file must contain information about encapsulation type so that Wireshark would know which dissector to use for each frame as the first one. So could you please tell how the offset should looks like for a frame like that ? I would also be very glad for a little guide which would told me how to apply the offsets on every frame, so I would be able to import other frames to the wireshark on my own. I think that is the problem why wireshark wont accept my frame. This are the numbers which you can see in the article on which I posted a link above. ![]() I am aware that I have to put in every line of the frame so called offset. I believe that solution is pretty simple and I am just stupid. When I was trying to import a frame I followed this guide: But still it didn't work. I have a problem with importing a frame from hex dump. ![]()
