["Gianluca Varenni" <gianluca.varenni@xxxxxxxxxxxx>]

that's because you are not calling the pcap_dumper function from within the pcap_loop callback.

your "my_callback" function simply prints out "Welcome".

 

Even if you are running on *nix, I suggest you to have a look at the samples included in the WinPcap developer's pack (examples-pcap folder).

 

Have a nice day

Subject: [Wireshark-dev] request help for packet capture using libpcap

Hello ,

 

I have been trying to write a small application using libpcap library.

Purpose is to capture some live network packets(say 100 packets) and store them in a file (pcap_savefile).

 

Please refer the attachment for the code.

 

As per my understanding the pcap_savefile should be in "pcap" format as this is the default file format for libpacp.

But when I pass this file to wireshark, it does not show any packet data.

Also the size of the pcap_savefile is just around 24 bytes for 100 packets.

So I was wondering whether the programm is actually capturing any network packet.

 

Could anyone please suggest how I can improve the programe and store the data in pcap format.

 

Thanks in advance.

 

Regards,

Atdev
