Opening multiple Terminals using C++

[Jayhawk420]

I'm trying to have my C++ program open a new terminal and execute that program. But the problem is that the program requires root to run. So far i have this

void airodump()
{

	string cmd= "gnome-terminal -e \"su - -c \" airodump-ng ath0\"";
	
	system(cmd.c_str());
}

Now the problem is that the last arg "ath0" isnt getting passed though correctly. I was wondering if there was any way to create a new terminal session besides the way ive tried.

Are you missing a double quote?

string cmd= "gnome-terminal -e \"su\" - -c \" airodump-ng ath0\"";

[Jayhawk420]

No, i'm beginning to think it isnt possible with that command because it calls 2 commands that each have arguments and the double quote will close the statement.
With what you suggested i get this :

Unknown option -c
Run 'gnome-terminal --help' to see a full list of available command line options.

What distribution are you using? You may want to check out consolehelper(8).

Fedora 10 x64. consolehelper(8) doesnt work for me . Is there a way to just open up a 2nd terminal and be able to run commands in it using C++, instead of the way i'm trying? Like having a function to execute commands in one terminal and another one in the second.

Make your executable setuid root?

[Jayhawk420]

This is what i get then

(gnome-terminal:1682): GnomeUI-WARNING **: While connecting to session manager:
None of the authentication protocols specified are supported.

I think I will just write a bash script and have the program execute it, its not what I really want but it will be a work around till I can find another way.

In your original string, you have THREE escaped double-quotes. That's why I added one (now that I look back, in kind of a pointless place). So maybe try adding/removing escaped double-quotes. Here are some possibilities.

string cmd= "gnome-terminal -e su - -c \"airodump-ng ath0\"";
string cmd= "gnome-terminal -e su - -c airodump-ng ath0";

[Jayhawk420]

The first one gives:
Unknown option -c airodump-ng ath0
The second gives:
Unknown option -c

The problem is gnome-terminal runs the su command and the su command to run airodump-ng ath0. I do not think that it is possible to run both of them from one single line the way i'm trying to do.

Have you tried other quoting possibilities, like this:

string cmd= "gnome-terminal -e \"su - -c airodump-ng ath0\"";
