In the frame of the dialog you can set the which is shown after connecting to the FTP server.
If you check the option, all local users will be placed in a chroot jail in their home directory after login. This option has security implications, especially if the users have upload permission or shell access, so be careful enabling this option.
If you check the option, all FTP requests and responses are logged.
You can limit permissions of files created by anonymous and/or authenticated users with umask. The bits that are set in the umask identify permissions that are always to be disabled for newly created files. Set the file creation mask for anonymous users in and the file creation mask for authenticated users in . The masks should be entered as octal numbers with a leading zero.
In the frame set the directories used for anonymous and authorized users. The default FTP directory for anonymous users is /srv/ftp. Note that vsftpd does not allow this directory to be writable for all users. The subdirectory upload with write permissions for anonymous users is created instead.
NOTE: The pure-ftpd server allows the FTP directory for anonymous users to be writable. Make sure you removed the write permissions in the directory that was used with pure-ftpd before switching back to the vsftpd server.
