C ++无法使用Ubuntu和Netbeans 6.9打开原始套接字

Question

I'm trying to send/recv raw ethernet under Ubuntu.

I've no problem running code in c through the terminal.

However when i've tried to convert the code to c++ using Netbeans IDE 6.9 it fails to open the raw socket. calling:

socket(PF_PACKET, SOCK_RAW, htons(ETH_P_ALL))) == -1)

always return -1. error : "operation not permitted"

Answer 1

You always need root permissions to send / receive something through raw sockets .

Here's how to configure NetBeans to run your application as root:

1. Right click on project -> Properties -> Run
2. Set Run Command to sudo "${OUTPUT_PATH}" (default is "${OUTPUT_PATH}" )
