E-mail is a service that we often use in our life and work to contact friends and customers all over the world. Below we will use Wireshark to grab the email packet.Preparatory work:Mail client section (Outlook,foxmail,koomail,...)Wiresharke-mail Test account twoMessage-Related Protocol knowledge (SMTP protocol, POP protocol, IMAP protocol)1. Mail client settings[1]. Open Foxmail for Account setup[2] After a successful setup, do not send a message bef

it is handed over to the application process. The latter method will improve the system efficiency. For example, the sender continuously sends a TCP datagram of 100 bytes in each packet, whose serial numbers are 1,101,201 ,..., 701. If the other seven datagram packets are received, but the 201 datagram is not received, the receiving end should confirm the two datagram packets 1 and 101 and submit the data to the relevant application process, the five

Learning computer network for a long time, but always confined to the book knowledge, feeling get not focus. After senior proposal with Wireshark grab packet analysis look.I have not done my own scratch bag analysis, so this blog post may have a lot of errors, but I own a record, the passing of the pro do not as a tutorial, so as not to go astray ....TCP protocol Header:Set in filter to:IP.DST = = 222.199.1

First run the Wireshark on the target a machine and open the browser, turn off other network-occupied software before opening, here I take 51cto.com to do the test.Normal login 51CTO User Center, use at this timeHttp.cookie and Http.request.method==postThe syntax filters the packets captured by the Wireshark., expand the Hypertext Transfer Protocol item to view the cookie information that was captured and c

1. Enable the rpcapd service on the remote host Take windows as an example. Check that Winpcap has been installed, switch to the Winpcap directory, and run Rpcapd-B IP address-P port number-l IP address of the host that allows remote packet capture-n The specific usage of rpcapd can be queried through rpcapd-H. 2.

Wireshark packet capture Analysis of TCP establishment and disconnection Process 1. Establish a connection over TCP Note: In this figure, Hosta acts as the client and hostb acts as the server. TCP is the transport layer protocol in the Internet. It uses the three-way handshake protocol to establish a connection. When the active Party sends a SYN connection request, wait for the other party to answer SYN, A

At this time the server will first send HTTP headers to the browser, the priority is higher than the page stated that the code is high, the natural browser is identified wrong. There are 2 solutions, please add a adddefaultcharset GB2312 to the config file's own virtual machine to cover the global configuration, or configure it in the. htaccess of your o
