vsftpd를 IPv4로 변경하는 방법은 무엇입니까?

vsftpd.conf에서

# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# Make sure, that one of the listen options is commented !!
listen_ipv6=YES

IOW IPv6을 비활성화하지 않는 한 아무것도 변경할 필요가 없습니다.
