ftp and folder quotas


ftp and folder quotas Ned

iis ftp: I think I already know that what I'm requesting is impossible, but I thought
I should ask in case I'm wrong ;)

A client has requested an anonymous ftp site (IIS6). I told them it would
have to be read-only, I don't want anonymous users reading and writing,
because otherwise the site would be used for nefarious purposes. But they
asked if it is possible to make a subfolder writable by the anon user, and
have this subfolder have a size quota, so that if it were subverted at least
the entire volume wouldn't be filled up.

As far as I know in win2003, storage quotas are configured for a volume (not
a folder), on a user-by-user basis. Furthermore, I know of no way to specify
a different anon user for a subfolder from the one at the root (because if I
could just use a different anon user in the folder, then my problem would be
solved and I'd apply a quota against that user only).

Is this all correct or is there some special workaround that I'm not aware of?

Thanks.

The obvious workaround would be to create a new partition, of a small size,
and have the directory be a virtual directory that pointed to the new
partition.

Partition size limits are as absolute as any quota I can think of.

But you might want to ask your customer if that's really the best scenario -
after all, if the warez banditz go after his FTP server, he's reached the
situation where his bona-fide customers are frozen out of uploading to the
upload directory.

A better solution is to have a specific (non-anonymous) user name and
password that is used only for uploads. Change the password weekly or so,
and give it out to those customers that need to upload.

Thanks a lot; yep, I thought about creating a new partition but forgot to
mention it. That's just what I thought -- well I convinced the customer that
a non-anonymous username and frequently-changed pw was the way to go.

Thanks again.
