Wait wait wait...

you're creating directories that the USERS own?  The webserver user won't be
able to access those directories unless you do something kind of tricky..

The first and only thing that comes to mind is that you'd have to create a
group for every new user.  The only two members of this group would be the
user and the webserver user.

When you chown the directory to the user, should also at this time set the
group owner to be the same as the webserver, and the rwx permissions on them
to be full for the group as well.

It sounds like it might be a pain to implement.

If you just create one group and put all the users into it, each user would
be able to get into all other users' directories.


Personally, I think a cleaner approach would be to have each user's file
directories under a userfiles/ directory from your html and php source, and
have it be owned only by the webserver user.

each user would have userfiles/username created for them, and they can
upload and download to their directory from the web.  What's nice about this
is that you can limit access to these directories via your own
authentication scheme, if you want.

I don't think you'll be able to offer ftp access to these dirs, though.

maybe someone else has a better solution -- it's been a long day for me. =)

programatically



Hi Nik,
I am creating the directories on web server.
The idea is, my clients need to upload some files,
to be processed by programme, on server. I want their files to reside in
seperate directories ,created for them, while they register themselves with
my site, to keep their files safe and seperated.By using mkdir(), i am very
well able to create and assign permissions to these runtime created
directories , but due to the owner that is assigned to these , when they are
created, i am not able to upload files , thru php or ftp as well, coz owners
of these directories differ now. How do i cater to this problem ?

Thanks
Amit Deshpande
