Re: how can I modify the network packet payload?

The packet data is changed when I send and receive both on the
localhost. The tcp packets are changed, sent and recv all through
127.0.0.1. It works well on the same laptop.

But when I send and recv at different laptop through ad hoc network,
the receiver cannot receive anything. At the sender side, the packets
seem changed and sent out. And after 6 or 7 packets sent out, the
sender seems hanged there and will not send any more packets.

I believe that you need to update the checksum.
