出現(xiàn)這種問(wèn)題，
①首先檢查用戶對(duì)應(yīng)的角色名，然后看路徑設(shè)置是否正確，有沒(méi)有相關(guān)的權(quán)限，如果這些都沒(méi)問(wèn)題，然后就嘗試下面的操作：
②重起FTP服務(wù)，最好從服務(wù)里面重啟(不能根本解決)；
③重新設(shè)置Server-U帳號(hào)和目錄訪問(wèn)里的文件路徑(如果還不行，嘗試下面操作)；
④刪除用戶，重新建。

有時(shí)ftp上傳，下載時(shí)，總是連接出錯(cuò)，無(wú)外乎以下原因，僅供參考：

Serv-U BBSFTP 提示信息詳解
1。 550 Not enouth credit to download .(bbsftp v2.6CE)


該提示信息一般在下載文件時(shí)出現(xiàn)。該提示表示您當(dāng)前的下載流量不夠。

2。530 Not logged in.(bbsftp v2.6CE)[FTP<202.15.29.29:21> User<rick> DB-FtpUserDown]

該提示信息一般在登錄失敗時(shí)出現(xiàn)。該提示表示用戶 rick 在FTP 202.15.29.29:21 中不存在.

3。530 Not logged in, unauthorized IP address.(bbsftp v2.6CE)

表示IP地址未授權(quán),包流量用戶或包時(shí)間用戶一般修改允許登錄的IP地址范圍后就可以登錄了.

公共帳號(hào),首先需要進(jìn)行購(gòu)買,才能登錄.否則也會(huì)有這個(gè)提示信息.這樣做是為了防止公共帳號(hào)被盜連.

4。530 Not logged in.(bbsftp v2.6CE)[BadPassword][3]

這個(gè)提示信息很明確了，密碼錯(cuò)誤。

5。530 Not logged in.(bbsftp v2.6CE)[UserDBError-FTP_USERS]

出現(xiàn)這個(gè)提示一般是參數(shù)設(shè)置錯(cuò)了，如果沒(méi)有定制過(guò)數(shù)據(jù)庫(kù)視圖FTP_USERS，請(qǐng)?jiān)谠O(shè)置中 將是否使用數(shù)據(jù)視圖設(shè)置為不使用。

6。530 Not logged in.(bbsftp v2.6CE)[UserDBError-FtpUserDown]

出現(xiàn)這個(gè)錯(cuò)誤一般是數(shù)據(jù)庫(kù)出問(wèn)題了，可能是mysql字符集設(shè)置導(dǎo)致的，如果是免費(fèi)版的bbsftp，還可能是mysql的優(yōu)化設(shè)置導(dǎo)致的。

7。421 Your Account Is Expired!(bbsftp v2.6CE)

這個(gè)提示信息一般在用戶登錄時(shí)出現(xiàn)。意思是說(shuō)該賬號(hào)已過(guò)期。

流量購(gòu)買賬號(hào)，遇到這個(gè)錯(cuò)誤信息，一般在論壇上更新一下自己的賬號(hào)信息就可以了（在購(gòu)買界面進(jìn)行一次購(gòu)買操作）。

時(shí)間購(gòu)買賬號(hào)，那就需要在論壇上購(gòu)買賬號(hào)的使用時(shí)間了。

公共賬號(hào)密碼，很少遇到這種提示，如果遇到這個(gè)提示信息，表示公共賬號(hào)剛好多了密碼更新時(shí)間了，這時(shí)之前的購(gòu)買記錄都會(huì)被清空，您需要重新購(gòu)買公共賬號(hào)和密碼才能登錄。

8。421 Your Account Is Disabled!(bbsftp v2.6CE)

這個(gè)信息一般在用戶登錄時(shí)出現(xiàn)，表示該賬號(hào)被禁用了。只能聯(lián)系管理員解決了

9。530 Not logged in, home directory does not exist.(bbsftp v2.6CE)


一般在用戶登錄時(shí)出現(xiàn). 意思是說(shuō)用戶的根目錄不存在.

仔細(xì)檢查一下這個(gè)用戶,看看他 對(duì)應(yīng)的角色是否已經(jīng)配置了. 如果角色不存在顯然是有問(wèn)題的.

然后檢查其對(duì)應(yīng)角色里面的 FTP根目錄的設(shè)置, 看看該設(shè)置填的路徑在 ftp服務(wù)器上是否存在.

如果存在的一般是沒(méi)有問(wèn)題的. 要注意一下三點(diǎn):

1 修改角色設(shè)置后要重啟servu才會(huì)生效.

2 如果該路徑在ntfs格式的磁盤上,要保證ftp服務(wù)器有權(quán)限 訪問(wèn)這個(gè)路徑.

3 如果設(shè)置了本地目錄安全參數(shù). 該路徑必須是在安全目錄設(shè)置的路徑范圍內(nèi).


10。 550 Permission denied

一般是路徑訪問(wèn)規(guī)則的權(quán)限設(shè)置不正確，

首先檢查用戶對(duì)應(yīng)的角色名，

然后檢查角色的設(shè)置，看看是否設(shè)置了路徑訪問(wèn)規(guī)則的組號(hào)。

再檢查相應(yīng)的組號(hào)的路徑訪問(wèn)規(guī)則組，

看看是否添加了FTP根目錄的訪問(wèn)權(quán)限。

有時(shí)候因?yàn)閿?shù)據(jù)庫(kù)的原因?qū)е轮形淖址e(cuò)誤，可以試試用英文路徑名。

注意修改這些設(shè)置需要重啟servu。
