[NTLUG:Discuss] Socket error?

[Mohammad Saman]

Hi,

  I am new to Linux Socket programming. I am trying to open a Raw socket to read ip packets.
with:

   sockfd= socket(AF_INET, SOCK_RAW,0)

What happens is that sockfd returns a  "-1". I am logged in as root. The SUID  bit is set on the executable,and the excutable is owned by root, but I still cannot create a socket. Does anybody have any ideas why ? Thanks in advance.

Regards,
Mohammad Saman
