FTP help 12.04 Server

FTP help 12.04 Server

I am very new to Linux / Ubuntu so please excuse my ignorance.
I have installed ubuntu server 12.04. I have installed vsftpd. I have
edited vsftpd.conf and made sure I have uncommented local_enable &
write_enable are set to YES. The vsftpd service is running. Ports 20 & 21
have been allowed in ufw. I am able to ping to my router and also ping to
www.google.co.uk so as far as I am aware that means DNS is being resolved.
I can also log on via SSH with no problems at all (Not sure if that has
any relevance but thought I'd mention it)
What I can't do is connect using 'filezilla' , 'cuteFTP' etc. This is the
msg I get back from Filezilla
Status: Connecting to 192.168.0.2:21...
Status: Connection established, waiting for welcome message...
Response: 220 (vsFTPd 2.3.5)
Command: USER grant
Response: 331 Please specify the password.
Command: PASS *************
Error: Could not connect to serverAs I say I am very new at this so any
help would be much appreciated.
