這個表明對方未開機,也可能是對方不在你能訪問的範圍內.可能小區的伺服器檢修中.

這個一般表明對方已開機,但未開啟ftp服務（沒有開serv-u）
也可能為對方不提供在這個埠上的服務
*connecting to xxx.xxx.xxx.xxx, port 21 (#1)
connected. waiting for response.
disconnected from server.
connection attempt failed. waiting for retry...
出現這個信息實在是很倒霉,你極有可能把重試時間定的太短伺服器封了你喲！

user user
421 too many users - please try again later.
說明當前你所屬的下載組的下載人數已到上限,請過些時候再嘗試,用Flashget等的下載工具不斷嘗試聯接的人請講嘗試時間調大一點,否則會被伺服器封閉一段時間的IP
*150 opening ascii mode data connection for /bin/ls.
426 data connection closed, transfer aborted.
這種情況可能是你所在網路安裝了防火牆（或代理）,該防火牆（或代理）禁止來自遠程的連接,426 data connection closed, transfer aborted表明了這一點.這時候你可以使用被動傳輸模式（pasv模式）,來避免該限制,進行數據傳輸.
解決辦法是在該ftp標籤的站點設置中,設置為被動模式pasv模式.同樣,如果前面有網友出現200 port command successful.
連不上的情況,也用上面方法
