Today, we are working about capturing the PACP LOGS with the help of Wireshark. Organization following logs are helpful to investigate issues identified with network availability. Tcpdump utility can be utilized to gather logs from KALI Linux.
What does the tcpdump output look like? Tcpdump allows you to examine the headers of the TCP/IP. Apt-get install tcpdump. It can also be used to debug the network setup. Mostly tcpdump and wireshark are used combined. Network administrators capture the packets via tcpdump and then use wireshark to view/analyze these captured packets. “tcpdump -w” parameter is used to write out put of tcpdump to some file.
Wireshark is using for network tracing logs in Windows/Linux/macOS.
So let’s start…

How To Use Tcpdump
Select Capture – > Options
Select comparing network connector you are utilizing for your organization association and select the Start button
In the event that you need to screen association through a specific port number, you can set it up as well. In Capture Filter type the port you need to screen, for example tcp port 443 or tcp port 44445
In case you know that backup will not fail immediately, it means WireShark should be executed during some extended time (20 minutes +) it is a good idea to write the information to a file right after start. You can choose a file in the Output tab and set traffic and time limits for logs collection:
Step 3 Reproduce the issue without shutting the Wireshark application
Step 4 Click Capture – > Stop after the issue is imitated:
Step 5 Spare the caught information in default design (pcap) by clicking File – > Save as
