RE: [K12OSN] Homework DropBox Idea



Could this be done. . .wait a minute. . . this a linux server or a Winders 
one. . .?
Anyway, could you use root postexec on that folder and once the student 
logs out, root postexec could be used to move the files to another 
directory that you have access to but no one else does?

The student could drop the file there and even go back and change or 
delete it as long as they remain logged in but as soon as they log out, 
the post exec would move the files. And set the rights to rwx------ for 
all files that go in there so that only the user that dropped the file in 
there could read or change it.
