This is the config file from an install of ProFTPD 2.9.1. /disk01 is a read only section of the ftp server. Anonymous access is granted for everyone. In the directory /disk01/incoming you can write, but you can not overwrite or delete files or directories. This server is locked down pretty good for an anon server. Change setting to suit your needs.
The config file is named proftpd.conf. It can usually be found in the /etc dir.
