This is the difficulty we face when we modify packets with a text editor. Since we modified the length in the RADIUS, now there is a mismatch. It is because both protocols carry the payload length. Notice that ' Internet Protocol Version 4' and ' User Datagram Protocol' are highlighted with red color. Step-8: When you have done it correctly, you should see something like below.

Newer Wireshark versions may not support it, which does not mean we can not find a workaround.ĪLSO READ: Things to consider when creating CSR with OpenSSL Unlike newer Wireshark, Legacy Wireshark supports an experimental feature that lets you to modify a packet fields. Even though the internal functions are mostly the same, the different GUIs may provide different features. Newer Wireshark versions use QT (it is a cross-platform application development framework) based Graphical User Interface (GUI), while old versions of Wireshark use GTK (it is a free and open-source cross-platform widget toolkit for creating graphical user interfaces) based GUI. The answer to this question depends on what version of Wireshark you use. The user wanted to modify fields like source IP address, destination IP address etc. Recently, I have come across a question regarding editing a RADIUS packet with Wireshark on.

Method-2: Packet editing with a text editor.Method-1: Using Packet Editor in legacy Wireshark.
