I want to execute metasploit by two pipes to communicate with it, but I have troubles with that communication. When I run my program, I get this error: "stty: standard input: Inappropriate ioctl for device" and I don't receive the metasploit promt.
just select an exploit.
This is my code:

Okay, the question:

I'm having difficulty understanding the purposes of using dup/dup2 when involving forks.
for example, if we call fork() once, that is, we are creating a child process. In what cases would we need to use dup or dup2 to duplicate the file descriptors for standard output and standard error? What... (1 Reply)
Hi,
i have in one program such a pice of code
................
static int old_stderr_handle = -1;
static int old_stdout_handle = -1;
log_handle = open(log_file_name,O_CREAT|O_RDWR,932);
old_stderr_handle = dup(STDERR_FILENO);
if (dup2(log_handle,STDERR_FILENO) < 0)

int fd,rc;
fd = open("sample.DAT",O_CREAT | O_RDWR , 00777 );
rc = dup2(fd , 1 ) ;
close (fd );
return 0;
}
I used the above to redirect all the cout statements to sample.DAT. process is redirecting the output and I had two questions
1. All stdout/cout statements... (2 Replies)
Hi all,I'm reading <Advanced programming in the UNIX environment>,that book asked the reader to implement a function which has same functions with dup2 without calling fcntl.Could anyone give me a tip?Any help will be appreciated.:) (8 Replies)

Hi, I will try to keep my post as compressed as my title was.
I am writing on pseudo code on a recursive function that I want to read from the one-above function-run and then give the result to the function-run down below until a stop is triggered. Example:

is it possible to duplicate file descriptors(opened by a different process) with the help of dup or dup2. the two process do not share parent child relationship as well. (2 Replies)
What this code should do is: there are parent.cpp and child.cpp. Parent will send whatever is in the buffer to child and child will send back whatever received to parent. I do not know what I am doing wrong. I am confused what is missing in the parent and what else I should include into the child.... (1 Reply)

ioctl
IOCTL(2) System Calls Manual IOCTL(2)NAME
ioctl, stty, gtty - control device
SYNOPSIS
#include <sgtty.h>
ioctl(fildes, request, argp)
struct sgttyb *argp;
stty(fildes, argp)
struct sgttyb *argp;
gtty(fildes, argp)
struct sgttyb *argp;
DESCRIPTION
Ioctl performs a variety of functions on character special files (devices). The writeups of various devices in section 4 discuss how ioctl
applies to them.
For certain status setting and status inquiries about terminal devices, the functions stty and gtty are equivalent to
ioctl(fildes, TIOCSETP, argp)
ioctl(fildes, TIOCGETP, argp)
respectively; see tty(4).
The following two calls, however, apply to any open file:
ioctl(fildes, FIOCLEX, NULL);
ioctl(fildes, FIONCLEX, NULL);
The first causes the file to be closed automatically during a successful exec operation; the second reverses the effect of the first.
SEE ALSO stty(1), tty(4), exec(2)DIAGNOSTICS
Zero is returned if the call was successful; -1 if the file descriptor does not refer to the kind of file for which it was intended.
BUGS
Strictly speaking, since ioctl may be extended in different ways to devices with different properties, argp should have an open-ended dec-
laration like
union { struct sgttyb ...; ... } *argp;
The important thing is that the size is fixed by `struct sgttyb'.
