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 packet, you can see the clear text user name and

I tried to use a tool to crack it. I searched the internet and finally found a practical articleArticle. After reading this article, I have a general understanding of the entire cracking process. in the past, ADSL users used the PAP protocol or Chap protocol in the PPP protocol for identity authentication. Since the PAP protocol uses plaintext to transmit key information, you only need to establish a pppoe server and use the PAP protocol for identity authentication, when the vro communicates
