Question: How to configure Vsftpd in HC Linux?
To resolve this problem disallow anonymous user access in vsftpd.conf.
The original configuration file for vsftpd is perfectly suited to a secure anonymous FTP server and makes a good basis to start customizing. It should be backed up to ensure any errors; it can be restored quickly from a known good file.
# cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.original
# vi /etc/vsftpd/vsftpd.conf
The default setting for allowing anonymous users is YES. To disable anonymous access it is not enough to comment out the following parameter, it MUST be changed to NO, otherwise anonymous still has access.
Now, Restart the service for the changes to take effect, with following command:
service vsftpd restart
