To make a long story short, Wireshark has a follow TCP stream feature, which is handy. The drawback is that the extracted stream data does not have time stamps and other information, in the analysis of data delay and packet loss is somewhat inadequate. In this case, a simple follow TCP stream function is implemented with Python, while the TCP information is preserved.The principle is simple and is still based on W
). TCP provides high reliability data communication for two hosts. His work involves dividing the data that the application gives to it into appropriate chunks to the network layer below, confirming the packets received, setting the timeout clock for sending the last confirmed packet, and so on. Because the transport layer provides high reliability end-to-end communication, the application layer can ignore all of these details. UDP, on the other hand, provides a very simple service for the appli
The new version of Wireshark can parse NB-IoT cell messages, and of course the stored message formats need to be converted to the. pcap format Wireshark can parse. The analytic format of Wireshark can be used to understand the protocol flow and the meaning of individual cells. Wireshark Setup Preparation 1, edit-by pre

First, you must have a certificate in. pem format.
Windows certificates are exported from the. pfx file. This format can also be used on the official website, but I still failed to try it n times.
Finally, only. pfx can be converted to. pem format.
My Wireshark version is 1.4.4 and Winpcap version is 4.1.2.
First, convert. pfx to. pem.
1. Download OpenSSL.
2. Export the certificate. Here I export it to D:/test. pfx.
3. pfx to PEM
