In Solaris, you don't have permission to access a file in /proc/<pid>/fd unless you can control the process<pid>. $ ls -l /proc/1/fd /proc/1/fd: Permission denied If you can control<pid>, then clearly you have access the file anyway simply by controlling it using a debugger.
In Linux the same access rules apply. -- Sincerely Your, Dan.
