Capturing a sniffer dump on a linux machine is easy, we can install the tcpdump package to capture network packets and write these to a file for further analysis with wireshark.
- apt-get install tcpdump
- tcpdump -i <interface> -s 65535 -w <some-file>
You can transfer the file thereafter with WinSCP to your Windows station for analysis.
Sniffing on the linux machine with redirection to your Windows wireshark
If you have putty and plink installed, you can also capture directly on a remote linux machine and redirect this to your windows station’s wireshark for realtime analysis.
If you are using password authentication on the linux machine:

- “C:Program Files (x86)PuTTYplink.exe” -ssh -pw password root@somemachine.localdomain tcpdump -n -nn -s 0 -U -w – -i bfe0 vlan 99 and icmp | “C:Program FilesWiresharkwireshark.exe” -i – -k
Or if you’re using key based authentication:
- “C:Program Files (x86)PuTTYplink.exe” -ssh -i “C:mykeystoresomekey.ppk” root@somemachine.localdomain tcpdump -n -nn -s 0 -U -w – -i bfe0 vlan 99 and icmp | “C:Program FilesWiresharkwireshark.exe” -i – -k
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.
Wireshark is using for network tracing logs in Windows/Linux/macOS.
So let’s start…
Requirements:
- Windows OS
- Wireshark
FIRST Step to Download the free Wireshark utility and install
Download the free Wireshark utility for Windows. If you do not want to install Wireshark on your system, then it is recommended to download and run the portable version.

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:
