 We assume that the target server and the online server are on the same network segment. The following command demonstrates how to use tcpcopy to capture and send requests.
 
 ```shell
-sudo ./tcpcopy -x 80@00:13:21:B2:5E:42-122.55.176.148:18080@00:0F:1F:03:F2:E6 -s 10.110.12.162 -o eth1 -i eth0

+This command captures requests to port 80 on the online server and forwards them to port 18080 on the target server (IP `121.55.111.148`). Specifically:
 
 - `tcpcopy` captures packets on interface `eth0`.
 - Packets are sent from MAC address `00:13:21:B2:5E:42` (associated with `eth1`) and forwarded to the target machine's MAC address `00:0F:1F:03:F2:E6`. Since both are in the same network segment, the next hop MAC is the target machine's MAC.
