It is also possible to search for characters appearing anywhere in a field or protocol by using the matches operator.
Match packets that contains the 3-byte sequence 0x81, 0x60, 0x03 anywhere in the UDP header or payload:
udp contains 81:60:03
Match packets where sip to-header contains the string "a1762" anywhere in the header:
sip.To contains "a1762"
The matches operator makes it possible to
The previous article builds the foundation of a UDP multicast program. The so-called Foundation is to look at it. I can write a simple multicast program and start working on it.
Where will the multicast content come from and what content will be broadcast? Haha, there is a device that does not have a communication protocol. It uses Wireshark to capture packets, analyze protocols, and program implementation

Install Wireshark on Ubuntu 12.04 LTS and limit the packet capture to a group, which is the Wireshark group. I believe you can use these instructions to install Wireshark on other distributions.Although you can only read my test on Ubuntu, I will modify these instructions if it is not appropriate to tell me at any time.First, we install
Wireshark Introduction

Wireshark is a very popular network packet analysis software with powerful functions. You can intercept various network packets to display the details of network packets.
Wireshark is an open-source software that can be safely used. It
I recently learned about UDP programming and got a big head. I have found a lot of materials and consulted many colleagues. I think the following information is well written, so I collected it for reference.1. During UDP programming, the most common question is how many bytes are sent at a time?Of course, there is no unique answer. The answer to this question varies with the requirements of different system

Analyze pvs pxe startup data packets using Wireshark Tracing
Citrix Provisioning Service uses PXE technology to start virtual machines for users.
First, the VM must be set to enable the NIC by default. The NIC sends a FIND frame through PXE bootROM in the network. The data frame contains its mac nic address. After the DHCP server receives the data frame, packets are returned to the NIC, including IP addresses, subnet masks, and gateways allocated by D

I tried to use a tool to crack it.
I searched the internet and finally found a practical articleArticle. After reading this article, I have a general understanding of the entire cracking process. in the past, ADSL users used the PAP protocol or Chap protocol in the PPP protocol for identity authentication. Since the PAP protocol uses plaintext to transmit key information, you only need to establish a pppoe server and use the PAP protocol for identity authentication, when the vro communicates

2. How to use the Wireshark Lua plugin
The LUA text that will be written (assuming Rssp2.lua) is placed in the Wireshark installation directory, where it can be placed as long as Dofile adds a path.
and locate Init.lua in the installation directory, and add the path code to the last line:
Dofile (Data_dir ... " Rssp2.lua ")

After installing Wireshark in Deepin store, it will be an error to catch the packet, which is a privilege issue, which is not used.Because the core file of the Wireshark parser is the/usr/bin/dumpcap executable file, it is mainly to set permissions on this file, in order to facilitate management, through a Wireshark user group to manage all users using

Because of the work required, I have written a wireshark plugin that resolves the internal communication protocol, and the plugin was written in Lua, so the Wireshark had to support LUA access.Typically, wireshark in Windows is supported with LUA after it is installed with the installation package. Just the default LUA support is off, and a search on the web will

When the DHCP server receives an IP lease request from the target device, it provides an IP lease. DHCP retains an IP address for the target device and then unicast a DHCPOFFER message to the target device over the network. The message contains the MAC address of the target device, the IP address provided by the server
