both ADO and JDBC has found a response latency issue. Communicating with the customer's IT staff that a Cisco firewall has been passed from the application server to the database. We are in the application server, application server-side switch, database server-side switch, database server, 4 points for network capture. After comparison, it was found that the data packets of two switches before and after the firewall were obviously problematic: there was a very obvious case of

Sometimes, when testing the network application, for the convenience of development, we will be at the same time to open the client and the Test side, for the third-party library, because it can not debug, may need to capture the package for analysis, today with Wireshark based on the port to grab the packet, found how to get down, online search, Wireshark does n

This article mainly introduced the Wireshark to crawl the local loop data packet and the method which takes out the data, needs the friend may refer to underOne: The NPF driver isn ' t running this error is caused by not opening the NPF service. NPF, the network packet filter (Netgroup Packet FILTER,NPF), is the core p

Use Wireshark to crawl the Telnet destination IP address (telnet 192.168.88.1)1, first open the Wireshark, then select the network card, click Start.2, in order to enter Telnet or input in the filter (IP.DST = = Destination IP address and tcp.port== 23).3, look at the following packet, find Telnet and be able to see the data:\r\n;4, then look at the following

The TCP protocol specifies a server port number for the HTTP process , typically a request by an HTTP client to establish a TCP connection to the server-specified port (by default, port 80). (Note that this refers to port 80 for server development) The HTTP server listens on that port for requests sent by the client.Open the Wireshark grab packet, filter the HTTP protocol, File–export objects–http Select th

You can export the packages captured by Wireshark: file-> export-> File You can select the export format under packet format, but if the required data is a combination of multiple packages, it will be troublesome, because the exported data will add the header information of the link layer, IP layer, and Transport Layer in any case, it is basically possible to manually delete the data. For example, I capture

Last week in the company encountered a problem, with Wireshark capture system to the network management reported data found that there are many messages are identified as "TCP segment of a reassembled PDU", and each piece of the message is 180Byte, at that time to see such an identity, Think is the IP message Shard, thought the System interface MTU value for the setting is small, through the command query found is 1500, has not been reset, at that tim

Install Setcap, Setcap is part of the Libcap2-bin package, in general, the package is already installed by default. sudo apt-get install libcap2-bin2. Create Wireshark Group. This step will also be completed when installing Wireshark, sudo groupadd wiresharksudo gpasswd-a yoso

Tcpdump and Wireshark are essential tools for network analysis, as are web analytics on mobile phones. Before that, I used the tcpdump grab package on my phone to save it as a. pacp file and then use Wireshark on my PC to analyze it. After seeing the contents of the reference site, I found that there are more simple methods, through the ADB foward function, you can directly on the phone tcpdump bag results

Recently in the use of Wireshark grab Bag tool, the old feeling this thing with very simple, powerful, so want to understand his implementation principle, I am curious to write a basic function of the demo bar.In fact, called grab bag tool, in fact, crawl through their network card all the IP packets, we can follow the IP packet protocol resolution not on the line.The core of implementation is here:1 //Crea
