LINKTYPE_IEEE802_11_PRISM (119), in which the packet data begins with a Prism header giving some metadata for the packet, followed by packet data that looks like Figure 8-1 of IEEE Std 802.11-2012.the packet data begins with the Frame Control field, followed by the Duration/ID field, followed by the Address 1 field, etc. LINKTYPE_IEEE802_11 (105), in which the packet data looks like Figure 8-1 of IEEE Std 802.11-2012, i.e.If you have 802.11 traffic, the link-layer header type will be one of: Here is a description of the link-layer header type values. The lowest-level contents of the packet are described by the link-layer header type value in the Interface Description Block for the interface on which the packet arrived. Each packet has an interface ID value, which refers to one of the interfaces described by Interface Description Blocks in the file. In pcap-ng files, packets are in Packet Blocks, Enhanced Packet Blocks, or Simple Packet Blocks Wireshark uses Enhanced Packet Blocks. In pcap files, packets are in the records that appear after the file header, and the lowest-level contents of the packet are described by the link-layer header type value in the file header. Older versions defaulted to pcap newer versions default to pcap-ng. Just remember to replace 127.0.0.1 with the IP of PolarProxy in case it is running on a remote machine.Here's a description of the pcap file format, and here's a description of the pcap-ng file format those are the two standard Wireshark file formats. This setup works on Windows, Linux and macOS. Click “Start” to inspect decrypted traffic from PolarProxy in real-time.Click “OK” in the Manage Interface window.Name the pipe and press ENTER to save it.There’s a little known feature in Wireshark that allows a PCAP stream to be read from a TCP socket, which is exactly what PCAP-over-IP is! To connect to a PolarProxy PCAP-over-IP service on the local PC, do as follows: I have previously demonstrated how this decrypted stream can be read by NetworkMiner, but it was not until recently that I learned that the same thing can be done with Wireshark as well. If you start PolarProxy with “-pcapoverip 57012” then a PCAP-over-IP listener will be set up on TCP port 57012. PolarProxy comes with a feature called PCAP-over-IP, which provides a real-time PCAP stream with decrypted packets to connecting clients. Users who wish to inspect the decrypted TLS traffic in Wireshark typically open this file from disk, but that doesn’t allow for a real-time view of the traffic. PolarProxy is a TLS proxy that decrypts and re-encrypts TLS traffic, while also saving the decrypted traffic in a PCAP file. This blog post explains how you can configure Wireshark to read decrypted TLS packets directly from PolarProxy over a TCP socket. Did you know that it is possible to stream captured packets from a remote device or application to Wireshark in real-time using PCAP-over-IP?
