User Security Management

[Tamer]

Hello,

i'm a newbie to linux! I have a small problem.

the situation is as follows:
I setup number of users and added them to a group. now these users can manage their files inside a folder.
When a users (user1 for example) modify a file, then when i do 'ls -l' command will show that user1 is the owner of the file. when user2 modify the same file, then it'll show that user2 is the new owner of the file... the problem when i use FTP and user3 (who is also a trusted member od the same group) overwrite the same file, i doe not show that user3 is the new owner, but user2!

how can i make a way to know who modified a file?

Please help me!
:confused:

thanks,

tamer

I'd rethink your system a bit, cause your going to run into all sorts of problems. Now, when user 2 modifies a file that user 1 created... it shouldn't change the user (unless they did that themselves to actually gain access to the file - privledges)

What you need is a system similar to CVS...

i got your point, but in this case what can I do to keep track of who did the modifications last time to any particular file? (assuming that the user is using ftp to copy her changes).
