I'm migrating a site from another (foreign) server to mine. In order to do this, I need to get write access in the vhost's webX folder (/var/www/clients/clientY/webX) but can't find the thread here where I've seen the required command. I know it has a special permissions setting that even prevents root from having write access. But I would like to know how to (1) enable write access, (2) set it back to normal (read only). Anyone know?
