How to forward Wireshark processed data to python? in what kind of method?

阅读更多关于 How to forward Wireshark processed data to python? in what kind of method?

问题 The Wireshark is a powerful tool for network traffic analysis. But from my practice, it can only export the processed data(which means, tell you which part is what, e.g. "data":123456 and so on) to .pcap file, but I would like to output 'data' segment in every TCP packet in real-time(or 90% real-time) to other application such as my python script for further use(may be via TCP forward?pipe?) I don't know how to get it done exactly. Is anyone feel willing to help me with this? Thank you~ ps:

手机抓包的两种方法：wireshark抓包和fiddler抓包

阅读更多关于手机抓包的两种方法：wireshark抓包和fiddler抓包

1、电脑做wifi热点，手机连上后电脑上使用wireshark抓包该方法手机无须root，并且适用于各种有wifi功能的手机（IOS、android等）、平板等。只要电脑的无线网卡具有无线承载功能，就可以。方法如下： 1.把电脑的网络做为热点 2.开启wifi热点后，被测手机连接到该热点； 3.启动wireshark，选择做为热点的网卡，点击start开始抓包； 4.操作手机，可以抓取到手机所有与网络交互的数据包，如需停止，直接点击wireshark的stop即可。 2、使用fiddler来抓取此方法只适应于抓取http。此方法的最大优点是，可以拦截发出或者收到的http，可以修改http的request和response数据。因此用此方法可以模拟一些特殊场景（如包无响应、模拟一些很难出现的错误码等）。此方法最好有一台拥有无线网卡的电脑。 1.电脑和手机连接到同一个局域网下（如电脑和手机连接到同一个wifi下） 2.电脑打开fiddler，在fiddler下，Tools-fiddler options，在connections选项卡下设置监听的端口号和勾选“allow remote computers connect”，点击“ok” 3.手机在wifi的选项下，选择**为“手动”，然后主机名填上电脑的IP地址，端口号填上刚才设置的“8888”后，保存。来源： CSDN 作者

问题 Completely new to Wireshark and wondering how to extract the data from the TCP packets which I receive on wireshark. I am currently using a raspberry pi with grove sensors and getting the values of pressure and temperature. I am sending these values to a server in cloud and it is working. I am using wireshark to trace the packets. Now I want to extract the data (i.e the pressure value and temperature value) from the packets and store them in a file for further implementation. Is there a way

问题 So I'm trying to get a script working with tshark on my CentOS 7 server, but I'm having problems. The script works fine on my Windows laptop, I just put it in the plugins folder in appdata, but I can't find the similar location on linux. I used yum to download wireshark, and I have the program in another of my folders, but I can't find either of the init.lua files or the plugins folder. When I use tshark -v it tells me it is built "with Lua 5.1" so I know that's not the problem, but I have no

Writing a Wireshark dissector to count number of TCP flows

阅读更多关于 Writing a Wireshark dissector to count number of TCP flows

问题 I have a very large tcpdump file that I split into 1 minute intervals. I am able to use tshark to extract TCP statistics for each of the 1 minute files using a loop code and save the results as a CSV file so I can perform further analysis in Excel. Now I want to be able to count the number of TCP flows in each 1 minute file for all the 1 minute files and save the data in a CSV file. A TCP flow here represents group of packets going from a specific source to a specific destination. Each flow

UDP is adding bytes to end of datagram?

阅读更多关于 UDP is adding bytes to end of datagram?

问题 I have a Linux UDP Server written in C and I am sending a UDP datagram of 16 bytes. All the data is received correctly by the client, but the wireshark log is showing that two extra bytes are being added: 00 16 00 00 c8 44 01 14 01 01 02 01 02 00 00 10 00 00 The two bytes are all zeros, I'm not sure where they are coming from, I have the data of 16 bytes sent in my sendto() function. These must be added on from padding at the Linux Kernel layer? Is there anyway to stop this from happening?
