thx , the command works now , i also have the probelm that when click smscon icon it just open the xterm then disappear , but when click the smscon editor icon it opens and i can edit the setting from GUI menu but it never Start the Smscon daemon after reboot. i enabled it from ' Enable Smscon on device boot ' setting . but each time i reboot the N900 and check the status i find it always Off and having to enable it .
