Hi,
I have a linux laptop. i have only loop back interface. i have a
small tcp client and tcp server running on the machine ( simple tcp
echo server and client ).
I would like to log these packets using , iptables -A FORWARD -p
tcp -j LOG. But there is no log getting captured when i execute
client and server ?
is there any way to produce this logs ( with only loop back
interface ) in forward chain ?

Packets going from your system to your system via loopback are not going
through FORWARD chain (there is no forwarding), they pass through OUTPUT
(as they are locally generated) and then through INPUT (they are locally
delivered).
