New magic number

["Francisco Mesquita" <francisco.mesquita () radiomovel pt>]

Hello,

 

I hope I'm making this request at the right place, if not please let me
know.

 

I'm working in my graduation project with libpcap, and I want to add
some information to the dump file, namely the address and netmask of the
probe, start and end time of the capture and received and dropped
packets during the capture interval.

To accomplish this purpose I need to add to the file header some fields,
for example as shown below:

 

struct pcap_file_header {

            bpf_u_int32 magic;

            u_short version_major;

            u_short version_minor;

            bpf_int32 thiszone;         /* gmt to local correction */

            bpf_u_int32 sigfigs;        /* accuracy of timestamps */

            bpf_u_int32 snaplen;      /* max length saved portion of
each pkt */

            bpf_u_int32 linktype;      /* data link type (LINKTYPE_*) */

 

            bpf_u_int32 address;

            bpf_u_int32 netmask;

            bpf_u_int32 starttime;

            bpf_u_int32 endtime;

            bpf_u_int32 recv;

            bpf_u_int32 drop;

};

 

Can you please assign me a new magic number so this format will be
recognized by libpcap?

If you need more information from me or you have any suggestions please
let me know.

 

Best regards,

Francisco Mesquita
