求助ftp问题。在ftp登入任何系统都出现530 Login incorrect.

kiss_qlh 2011-01-18 10:57:32
用调试模式打开ftp,如下:为什么不让我输入密码再发送密码给服务器。


<402 rptsrv01:/home/smsds>ftp -d 10.71.167.146
连接至 10.71.167.146
220 rptsrv02 FTP server (Version 4.2 Wed Jan 14 03:55:23 CST 2009) ready.
名称 (10.71.167.146:root):smsds
---> USER smsds
331 Password required for smsds.
---> PASS
530 Login incorrect.
登入失败。
ftp> bye
---> QUIT
221 Goodbye.


还有一台AIX服务器,我有4个线程能连接到ftp服务器,第5个线程就出现530 Login incorrect.错误。

求助!!~~~~~~~~~~分就只有这么多了!

我这AIX不用vsftp的,不过问题解决了,是因为/dev/tty这个设备文件除了root用户外其他用户是没有可写的权限导致的。谢谢各位的回答!

看看/etc/ftpaccess.ctl
/etc/ftpusers

原因很多pam认证,其中pam中还有库版本等问题

检查/etc/vsftpd/user_list和/etc/ftpusers,是这个文件/etc/vsftpd/vsftpd.conf 是否少了一行:
pam_service_name=vsftpd
