about libnet

Hi all,

I am new to libnet and the list. Could anybody confirm that whether libnet
is able to do the following jobs:

1. Capture incoming packets and examine/store their contents;
2. Kill these packets (stop forwarding them to other peers or upper layers);
3. Re-construct these packets according to the stored contents and send them
at anytime and in any order and insert them into the IP stack.

Thanks in advance!

Regards,
Jee
