As long as you can't prevent user from calling normal win32 applications (such as as cmd.exe) and win32 APIs (like CreateFile ()) he will be able to accesss any drives on your system you're supposing to prevent him from. Your only gain will be false sense of security. The way to achieve real security is to set proper access rights for all files on all filesystems on your host and all other hosts this user can log into. egor -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
