What is the tcpdump command in Linux?

How do I capture a PCAP file in Linux?

I want to capture a network traffic and I use the following command: pcap -c sample.

Pcap However, the PCAP file looks like: ? It depends on the application you are using. If the application is using the libpcap library, then you can just redirect the capture output to a file by passing the -a option:/app -p tcp /path/to/capture.pcap
On Windows, the -a option would be something like: app.exe -a pcapfile.pcap
It is possible to capture with libpcap on Windows without redirecting capture output. To do this, you would use the windowsspecific option, like:exe -p tcp -w myfile.pcap
In the comments above, you asked for an example. On Linux: # wget. # rsync ./example.pcap /tmp/
# netcat -s -l -p 8888 pcap. On Windows: # rsync . Tee -a /tmp/captured.pcap
If you want to stream the data as it comes in, you can pipe the output from a netcat command like the following: # cat somefile.
