popen() ?
well, i tried something like this without luck,
maybe im doing a simple mistake, could you take a look at the code?
void init_password_callback(GtkWidget *dialog, gint response, char
*dev_mapper){
char *argv[5] = {"/sbin/cryptsetup luksOpen", dev_mapper, NULL, NULL,
NULL};
GError *error = NULL;
char* fifoname = NULL;
FILE* fifo = NULL;
GPid mount_pid;
char* passphrase = NULL;
if (response == GTK_RESPONSE_OK)
passphrase = gksuui_dialog_get_password(GTK_WIDGET(dialog));
if (!passphrase)
g_print("kein Password");
gtk_widget_destroy(GTK_WIDGET(dialog));
// g_print("PASS: %s", passphrase);
gchar pw[512];
gchar init_pw[512];
sprintf(init_pw, "/sbin/cryptsetup luksOpen %s", dev_mapper);
// g_print("ARGV_3: %s",init_pw);
FILE *fp = popen(init_pw, "w");
if (fp)
{
sprintf(pw, "%\n", passphrase);
fputs(pw, fp);
// fputs(pw, stdin);
}
return;
}
Since there is no -P option i cant do it via argv.
which is a good thing(tm)
i think that to, bash_history could make the whole thing useless...
thx
L.
