  12 00 00 ff d3 89 c3 57  68 04 00 00 00 50 ff d0

I try right click on the packet and select copy -> bytes ->hex stream but the hex data I got doesn't look like the above data at all so How Can I copy hex data of captured packet form wireshark ?

thanks for reading

Solution 1

On the Wireshark "packet list" panel, right click the packet you want and:

1) if you select Copy->Bytes->Hex stream, you'll get the hex digits as one long string without white spaces

 39cb08004528053f000000006f1105faac11745dac11740c039......

2) if you select Copy->Bytes->Offset Hex, you'll get the hex digits as displayed on the GUI , including the offset of each line starting byte (frame offset)

0010   05 3f 00 00 00 00 6f 11 05 fa ac 11 74 5d ac 11    
0020   74 0c 03 9e 03 9d 05 2b 00 00 07 e0 8f ee 8f 1c    
0030   ff 00 00 00 00 00 09 0f 00 58 39 cb 60 00 00 00    
0040   11 80 08 00 73 00 02 44 00 00 00 00 03 dd de de

Solution 2

If there are several packets you're interested in, you can export them to a file.

1. mark those packets (right click on each packet then Mark Packet (toggle) or Ctrl + M)
2. choose File > Export > File.... Make sure you select Marked packets.
3. if you're only interested in the hex data, make sure only Packet Bytes is checked in Packet Format

Note that when exporting you also have the choice with First to last marked as well as Range, if the interesting packets are next to each other.

later on , if you want to get rid of the line numbers (0010 0020 0030 etc.) you can open the hex block on any text editor (Notepad...) and using the Alt key then drag your mouse on the text , you will draw with that actio n a selection box on these chars , then press Del.

This is the only thing I needed from Wireshark and not intuitive at all. Why not allow copying text right from where I see it in Wireshark.

Any shortcut for that?
