wireshark capture

Great ~~ BasicIo graphs: Io graphs is a very useful tool. The basic Wireshark Io graph displays the overall traffic in the packet capture file, usually in the unit of per second (number of packets or bytes ). By default, the x-axis interval is 1 second, And the y-axis is the number of packets at each time interval. To view the number of bits or bytes per second, click "unit" and select the desired content f

. That is to say, it notifies the client that the server has received the SYN packet, by adding a serial number of the original SYN Packet and using it as the response number, the client then knows that the server can receive communications. ACKMessage: The 8 th packet is the confirmation message sent from the client to the server, telling the Server Client to receive the SYN/ACK packet, and the client also adds the serial number as in the previous step. This packet is sent completely, the clien

I wrote a blog post: Use Fiddler to debug HTTP and HTTPS. This article introduces wireshark, a useful packet capture tool, to obtain network data packets, including http, TCP, UDP, and other network protocol packets. I remember that I learned the TCP three-way handshake protocol when I was in college. At that time, I only knew that although I had read a lot of TCP and UDP materials in the book, I never real

Wireshark related tips, wireshark relatedThe Packet size limited during capture prompt indicates that the marked packages are not fully captured. In some operating systems, only 96 bytes are captured by default, the "-s" parameter in tcpdump can be used to specify the number of bytes to be captured. "-s 1500" means that each packet can

Tcp:TCP/IP establishes a connection through a three-time handshake. The three types of messages in this process are: Syn,syn/ack,ack.The first step is to find the first SYN message that the PC sends to the Web server, which identifies the start of the TCP three handshake.If you cannot find the first SYN message, choose the Edit-and find Packet menu option. Select Display filter, enter filter condition: tcp.flags, you will see a flag list for selection. Select the appropriate Flag,tcp.flags.syn a

Basic IO Graphs:IO graphs is a very useful tool. The basic Wireshark IO graph shows the overall traffic situation in the capture file, usually in units per second (number of messages or bytes). The default x-axis time interval is 1 seconds, and the y-axis is the number of messages per time interval.

I. IP address filtering: the source IP address or target IP address is equal to an IP address.For example, IP. src addr = 192.168.0.208 or IP. src addr eq 192.168.0.208 displays the source IP address.IP. dst ADDR = 192.168.0.208 or IP. dst addr eq 19
