Hello Arfat,

Also make sure that is is correct
"if you are running it under xinetd, you need to change the vsftpd.conf file to have it NOT listen on port 21 since xinted is already doing that and failing to bind the port makes xinetd whine and die.

turning

listen=YES

at the bottom of /etc/vsftpd/vsftpd.conf into

#listen=YES

will do the trick for you, I suspect. "
