I am hosting sevaral web sites in my linux apache server, and installed proftp as the ftp server. Now I want to creat ftpusers for every website so that my clients can maintenance their website, and they cannot leave their www folder during the ftp session. I also want to create a superuser who can maintain all the hosted websites. Now the question is how to set up file permissions under every www folder, say for website1 i have ftpuser1, so for the file index.html under www1, if I set up as
"-rwx-r-xr-x ftp1 guest ", then the superuser can't make changes to the file, in brief, can I set both the superuser the ftpuser1 as the owner of the file index.html?
