[CentOS] Vsftpd configuration problem

Greetings,

Beginning today, I started to receive the following when ftp'ing to my 
CentOS 6 machine:
ncftp /home/pyz2 > dir
connect failed: No route to host.
connect failed: No route to host.
connect failed: No route to host.
Falling back to PORT instead of PASV mode.

I can make a connection, but I can't get a directory listing or transfer 
data/files.

I'm flummoxed.

What I had been doing is adding more directives to my /etc/hosts.deny 
file, today to include certain categories of ip addresses for the vsftpd 
service.

I unwound that after I saw the problem starting to occur, and have 
restarted vsftpd several times.

That hasn't changed the above issue.

And yes, I've googled.

My firewall setting has port 21 open.

I can remotely telnet to hostname 21

and I get a response indicating that the port is open.

Any advice would be appreciated.

Much thanks.
