I got an information that tcpdump is same like wireshark. In using tcpdump we can capture the packets, but in wireshark we can see the GUI of packet capture. Later I understand that we can use the tcpdump command, it will capture the payload as well
tcpdump -nnvvXSs 1514 -i <interface> port 80 -w output.pcap.
Actually my company tells me that when ever calling an API we need to analyse the data using wireshark. I'm a beginner could you please tell me the what should I need to check with wireshark ? I know its a packet capture tool, analyse data inside packet. What should I learn ? What are the important point that should I keep while before capturing packets ? Is anything else other than packet capture ?
I got some incomplete data, when an incomplete response is resulting back to the console or whatever the tool that are using for the response and then when sniiff the data, it is showing the incomlpete data -it is called memory leak is it correct ?
, that I got after type the tcpcump command and then open postman call an http API request, then open wireshark and then anlalyse the packets...
Is I need to learn more tcpdump command to work with wireshark ? What are the testing possibilities of wireshark ? like vulnerabilties etc..
Which language that every one using in wireshark ? In coding what everyone finding using with wireshark ?
