I'm pretty new to debian, and I'm trying to set up a server.

I created a user which can only access to his folder /home/username (and its subdirectory).

Now I want to use that user for the webserver I set up, and I gave him access to /var/www but I can't see /var/www through sftp and i did a symbolic link like this

root@server:/home/username# ln -s /var/www www
root@server:/home/username# cd www
root@server:/home/username/www# chown username:username *

now, with filezilla, I can see www folder like this ->

but when I try to open it I get this ->

Where am I going wrong?

sorry for my awful english, i hope you can understand my problem...
