, we can see the user and pass that sent the message, but it is Base64 encrypted because SMTP does not receive plaintext. Frame 23rd and 26th, we can see the sender and the recipient of the sent message, which is clear text. Frame 32nd and Frame 34th, foxmail the size of the data sent by the client. Frame 36th is the message's account and subject information. Frame 39th disconnects the server. [3]. View the contents of an e-mail message[1]. Select the details of any frame of

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

, 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

Linux with tcpdump network traffic monitoring, export files get windows with wireshark analysis linux command line: tcpdump-ieth1-s0host10121293-woutputtxt-i specified on eth1 listen, this according to different machines, by default, tcpdump is used in eth0 linux to monitor network traffic. the exported file is obtained to wireshark in windows to analyze the comm

Wireshark (formerly known as ethereal) is a network packet analysis software. The function of the network packet analysis software is to capture network packets and display the most detailed network packet information as much as possible. Open source code. Sniffer Pro is a first-class Portable Network Management and Application fault diagnosis and

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 packet chaos, the

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

SYN ScanSYN Scan, according to three handshake, sends a SYN packet to the port, if the other party responds Syn/ack, it proves the port is openFirst, Nmap.Fast, 0.67 seconds to complete, see Wireshark crawlSend a large number of SYN packets at a timeThe 15,19,24 in the figure is the ACK packet returned by the open port of the scanned hostNext is the Metasploit scan module.The scanning speed of the Metasploit is slow, and it is obvious that the sweep s
