ftp 連線在伺服器詢問密碼之前關閉

當嘗試從 machine1 (SUSE Linux) 連接到example.comftp 伺服器時,在提示輸入密碼之前收到以下訊息。它從未驗證過密碼:

cata@machine1:~> ftp example.com
Connected to example.com.
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
Name (example.com:cata): [email protected]
421 Service not available, remote server has closed connection.

正如您所看到的,它甚至不驗證密碼。


但是當我從 machine2 (Ubuntu Linux) 連接時,它可以工作:

catalinubuntu@machine2:~> ftp example.com
Connected to example.com.
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 1 of 50 allowed.
Name (example.com:catalinubuntu): [email protected]
331 User [email protected] OK. Password required
Password:

正如您所看到的,在這種情況下,出現密碼提示並且我能夠登入。是否有我可以調整的 FTP 用戶端設定?
