I have a debian linux webserver with several client websites. Each client has an FTP account with their home directory set to /usr/local/apache/htdocs/client/<client_directory> and a default shell of /bin/ftponly.
How can I stop these clients from being able to 'cd ..' out of their home directory and right up to /?
I don't want any clients to be able to cd ../<another_client_directory> through FTP, but I need to keep read access open to anyone for webserving purposes
I am using ProFTPD 1.2.0.
Any help much appreciated.
