Hi List, sorry if this is a stupid question but I am not very familiar with gdb ;) I am planing a security application and gdb is causing some "troubles". Can someone point me to some infos or shortly explain me if there is a way to protect a program from attaching to it? I must either prevent gdb (or similar software) from attaching to a process or at least detect the attach and send a terminate signal to the application. best regards Oliver -- Protect your environment - close windows and adopt a penguin!
