Then I click the Insert Tracing Control Module button(The traffic light), after input the root passwd, I click start button, but an error message box pop up, the error message is "A problem occured when executing the su command : Operation not permitted". Please tell me why and how to solve this problem. One more question: I want to monitor a program which executed from bash, all the processes of this program execute. Include from bash to execv, how the dynamic loader loaded the elf file and the other libraries and so on. Does lttv can be competent for this work? Thank you very much! -- Best Regards! Shouwei Li
