如何处理Linux中vsftpd 530 login incorrect报错

　　方法一：

　　登录出现 vsftpd 530 login incorrect 报错。

　　解决方法：

　　cp Path/RedHat/vsftpd.pam /etc/pam.d/ftp

　　path为vsftp解压缩源文件目录

　　这是因为我们RHEL启用了PAM，所在用到vsftp时需要用到 /etc/pam.d/ftp这个文件（默认源码安装的不会有这个文件），因此除了匿名用户外本地用户无法登录。

　　方法二：

　　在测试Checkpoint的VPN1 R6x的时候，遇到了这个错误。这说明client端跟server端的连接性是没问题。但是就是想不出为什么，还以为是用户名和口令错误呢。后来才google了一下，发现是server端的配置有问题。

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

　　代码如下：

　　pam_service_name=vsftpd

　　$ echo ‘pam_service_name=vsftpd’ 》》/etc/vsftpd/vsftpd.conf

　　$ service vsftpd restart

　　530 error就消除了！

　　下面是更详细的方法：

　　［root@atr-3-server1 admin］# cat /etc/vsftpd/vsftpd.conf

　　# Example config file /etc/vsftpd.conf

　　#

　　# The default compiled in settings are fairly paranoid. This sample file

　　# loosens things up a bit， to make the ftp daemon more usable.

　　# Please see vsftpd.conf.5 for all compiled in defaults.

　　#

　　# READ THIS： This example file is NOT an exhaustive list of vsftpd options.

　　# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd‘s

　　# capabilities.

　　#

　　# Allow anonymous FTP？ （Beware – allowed by default if you comment this out）。

　　anonymous_enable=no

　　#

　　# Uncomment this to allow local users to log in.

　　local_enable=YES

　　#

　　# Uncomment this to enable any form of FTP write command.

　　write_enable=YES

　　#

　　# Default umask for local users is 077. You may wish to change this to 022，

　　# if your users expect that （022 is used by most other ftpd’s）

　　local_umask=022

　　#

　　# Uncomment this to allow the anonymous FTP user to upload files. This only

　　# has an effect if the above global write enable is activated. Also， you will

　　# obviously need to create a directory writable by the FTP user.

　　#anon_upload_enable=YES

　　#

　　# Uncomment this if you want the anonymous FTP user to be able to create

　　# new directories.

　　#anon_mkdir_write_enable=YES

　　#

　　# Activate directory messages – messages given to remote users when they

　　# go into a certain directory.

　　dirmessage_enable=YES

　　#

　　# Activate logging of uploads/downloads.

　　xferlog_enable=YES

　　#

　　# Make sure PORT transfer connections originate from port 20 （ftp-data）。

　　connect_from_port_20=YES

　　#

　　# If you want， you can arrange for uploaded anonymous files to be owned by

　　# a different user. Note！ Using “root” for uploaded files is not

　　# recommended！

　　#chown_uploads=YES

　　#chown_username=whoever

　　#

　　# You may override where the log file goes if you like. The default is shown

　　# below.

　　#xferlog_file=/var/log/vsftpd.log

　　#

　　# If you want， you can have your log file in standard ftpd xferlog format

　　xferlog_std_format=YES

　　#

　　# You may change the default value for timing out an idle session.

　　#idle_session_timeout=600

　　#

　　# You may change the default value for timing out a data connection.

　　#data_connection_timeout=120

　　#

　　# It is recommended that you define on your system a unique user which the

　　# ftp server can use as a totally isolated and unprivileged user.

　　#nopriv_user=ftpsecure

　　#

　　# Enable this and the server will recognise asynchronous ABOR requests. Not

　　# recommended for security （the code is non-trivial）。 Not enabling it，

　　# however， may confuse older FTP clients.

　　#async_abor_enable=YES

　　#

　　# By default the server will pretend to allow ASCII mode but in fact ignore

　　# the request. Turn on the below options to have the server actually do ASCII

　　# mangling on files when in ASCII mode.

　　# Beware that turning on ascii_download_enable enables malicious remote parties

　　# to consume your I/O resources， by issuing the command “SIZE /big/file” in

　　# ASCII mode.

　　# These ASCII options are split into upload and download because you may wish

　　# to enable ASCII uploads （to prevent uploaded scripts etc. from breaking），

　　# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be

　　# on the client anyway.。

　　#ascii_upload_enable=YES

　　#ascii_download_enable=YES

　　#

　　# You may fully customise the login banner string：

　　#ftpd_banner=Welcome to blah FTP service.

　　#

　　# You may specify a file of disallowed anonymous e-mail addresses. Apparently

　　# useful for combatting certain DoS attacks.

　　#deny_email_enable=YES

　　# （default follows）

　　#banned_email_file=/etc/vsftpd.banned_emails

　　#

　　# You may specify an explicit list of local users to chroot（） to their home

　　# directory. If chroot_local_user is YES， then this list becomes a list of

　　# users to NOT chroot（）。

　　#chroot_list_enable=YES

　　# （default follows）

　　#chroot_list_file=/etc/vsftpd.chroot_list

　　#

　　# You may activate the “-R” option to the builtin ls. This is disabled by

　　# default to avoid remote users being able to cause excessive I/O on large

　　# sites. However， some broken FTP clients such as “ncftp” and “mirror” assume

　　# the presence of the “-R” option， so there is a strong case for enabling it.

　　#ls_recurse_enable=YES

　　pam_service_name=vsftpd

　　userlist_enable=YES

　　#enable for standalone mode

　　listen=YES

　　tcp_wrappers=YES
