[SOLVED] Stop users moving up the folder structure?

daj_uk · 05-12-2011, 07:53 AM

Hi

I'm relatively new at the world of Linux so be gentle

I have a Ubuntu 10.10 server; I have created several users and wish them to have their own web space (with a unique domain name for each). I have therefore created www folders within their home folder and created new Virtual Servers to host each domain name and point to the users www folder in their home folder. They can then use an FTP client to upload files. This all works well.

However, I would like to stop a user from going back up a level and traversing the tree.

Assuming their home is /home/user2/www

They can currently go back up to /home and see other users names.

Can I stop this?

many thanks

Hello,

What ftp service are you using on your server? Most likely, the configuration needs to be changed in order to stop it.

Hi Josh

Thanks for the reply

I am running vsftpd

Code:

chroot_local_user=YES

That should do the trick for you man. Cheers,

Josh

To be more specific, corp's suggestion is to uncomment a line in the /etc/vsftp.conf file.

Code:

# Uncomment to put local users in a chroot() jail in their home directory
# after login.
#
#chroot_local_user=YES
