    master raw device?

    hi
    this code here should simply create a socket.
    Code:
    /*...*/
       int sockfd;
       if((sockfd = socket(AF_INET, SOCK_RAW, 0)) < 0)
          perror("socket");
       else
          return 0;
    /*...*/
    }
    when i compile my code i get no warnings but when running the program
    linux tells me:
    "cannot open master raw device: '/dev/rawctl' (no such file.....)

    i am running knoppix booting from cd, if that helps.

    thanks
    cu

    Try looking through these
    http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=cannot+open+master+raw+device%3A+%27%2Fdev%2Fr awctl%27&sa=N&tab=wg

    (put the url back together in your browser)
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
