Ftp doesn't know its username

“500 OOPS: vsftpd: cannot locate user specified in ‘ftp_username’:ftp”
I am getting this error when I try to run ftp
I am using localhost as qbox-host and 8081 as qbox-port.
Anyone???

Hey,
You will have to make some changes to your config file.
Hint: it is related to anonymous user.
