Default Allowing Anonymous write access only.



Hi

I currently have an NT4 server running an old version of IIS, this has
been set up so that anonymous FTP users have write access only, this
may seem insecure and we do get a certain ammount of hackers or
taggers testing the system by dropping test files and folders onto the
server, but because anonymous users do not have read access they soon
find that they cannot download anything they upload and go elsewhere.

Due to the demise of NT4 Support at the end of the year we are
currently replacing all our NT servers with either Win2000 or, as in
this case, Win 2003 Servers. This is where my problems have started,
I initialy replicated all the IIS setting and NTFS permission from my
NT box on my 2003 box but so far have been unable to achive the same
result, it appaers that I can only grant anonymous write access if I
grant read access as well, I've tried every different configuration I
can think of but come to the same conclusion.

The message I get on the screen when only write access is enabled
(useing NTFS permissions) is "cannot log in, home directory
inaccessible, Anonymous login failed."

If I enable read and write access I can login OK, write data and then
read it as well (as expected).

Can any one advise how I can set up FTP on my 2003 so that anonymous
users can only write data but cannot list or read anything ?

Thanks in advance.

Well, I have not tested this, but from the error msgs. I guess the anonymous
need at least READ permission for login. so you might grant READ only at
root, and create a directory /drop/ which allow the user to upload. also you
can get more hints from this article -

Hi Bernard,

The article gives details on how to do as you said and works very well
! The only change being I have to use a sub folder, not sure if this
will cause a problem for the users yet, I gues I'll find out soon
enough.

Thanks,

Phill.
