In Linux, It is very convenient to use tcpdump to capture packets, but Wireshark is more convenient to filter and analyze the captured packets. The following describes how to use tcpdump. Example: TCPDUMP host 172.16.29.40 and port 4600-X-S 500 Tcpdump adopts the command line method. Its command format is:Tcpdump [-adeflnnopqstvx] [-C quantity] [-F file name][-I network interface] [-r file name] [-s snaplen][-T type] [-W file name] [expression] 1. I

, I thought I could find the download link of the video directly in the package that Youku returned.Pondering for a second, the heart felt that this method should be feasible, and then open the grab bag artifact Wireshark.At the same time, click on the Youku homepage to open a video and let it start playing. Wireshark soon appeared a lot of packages, I added the filter condition "http", let it crawl only the HTTP protocol related packets.The focus is

, we can see the user and pass that sent the message, but it is Base64 encrypted because SMTP does not receive plaintext.

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

, the answer fields, the authorization fields, and the additional information fields are in the same format called the resource record RR (Resource record).The domain name is the name that corresponds to the resource data in the record. It has the same format as the Query Name field described earlier.　　 Type indicates the type code of the RR. Its value is the same as the value of the query type described earlier. Class is typically 1, which refers to Internet data.　　 The time to live field is th

, the source MAC address Send side IP address: that is, the source IP address Destination Ethernet Address: target-side MAC address (if Request message, is full 0) IP address: That is, the IP address of the end of the target Now that you know the detailed format of the ARP, try to get the ARP message. Instance: As shown in the figure above, PC1 sends an ARP request to PC2, at which point the ARP capture data is obtained using Wireshark

file We can start tcpdmup in adbshell. The command is as follows: Tcpdump-s0-v-wout.pcap For the complete tcpdump command parameters, see this address: http://www.tcpdump.org/tcpdump_man.html As shown in figure: As you can see, tcpdump monitors the data packets of the current Nic. To stop monitoring, you only need to CTRL + C to stop monitoring, use pull to save it to the file system to facilitate Wireshark

1. Test the machine, the source address IP is 10.21.28.110, the destination IP address is 10.6.0.24.2. Use IP.SRC = = 10.6.0.24 or IP.DST = = 10.6.0.24 filter rules to show only the data that 10.21.28.110 and 10.6.0.24 interact with.As shown, the ping command in Windows performs 4 ping programs by default, so Wireshark will catch 8 ICMP packets.3. Observe the first Echo (ping) request data frame that is numbered 2066.As shown, you can see the structur
