I need to block listing of parent directory. I have ftp configured to anonymous connection and set anon_root to /FTP directory.

My directory structure looks like this:
Anonymous users should access DIR_A and DIR_B but not parent FTP dir. I need this solution for scenario when users known only one unique directory name and have link for it, but should not "go up" and list other directories.

I hope I've describe my problem enough :-).

You can't as far as I'm aware .. users can see anything in a directory that they have access to, whether they have permissions to access the file or directory is a different matter.

you could try chmod 111 on the FTP directory and 777 on DIR_A and DIR_B. Taking away all but executable permissions should let the user into the directory but will not be able to read or write to just that directory, but will have full R/W access to DIR A and B. You will need to know the relative path to the dir you want to go into since you will not be able to see anything that is inside the FTP dir.

This is something you can try, i can got guarantee it will work.


edit: I have tested this out and i can confirm this will work.

Manually changing to the dir of my choice by knowing the path

Thanks.

I have tried this "configuration" earlier but it wasn't working. You gave me motivation to find out why...

I was using Nautilus (file browser) and it didn't show me those directories (not even when I browse them directly). But with FileZilla or Firefox it works just as was to be.
