#ncftp localhost 하면 잘 됩니다.
#ip addr

에서 아이피 61.43.30.83확인하고,
#ncftp 61.43.30.83 하면

Sorry, no server available to handle request on 61.43.30.83.
Server hungup immediately after connect.
Sleeping 20 seconds...
이렇게 나오네요.
만약, 전혀 ftp서버가 아니라면

Could not connect to localhost: 연결이 거부됨.
Sleeping 20 seconds...
