在Linux系統操作中，如果出現vsftpd 530 login incorrect報錯該如何處理呢？要想解決該問題，就要知道產生報錯的原因，下面小編就給大家介紹下Linux中如何處理vsftpd 530 login incorrect報錯。
方法一：
登錄出現 vsftpd 530 login incorrect 報錯。
解決方法：
cp Path/RedHat/vsftpd.pam /etc/pam.d/ftp
path為vsftp解壓縮源文件目錄
這是因為我們RHEL啟用了PAM，所在用到vsftp時需要用到 /etc/pam.d/ftp這個文件（默認源碼安裝的不會有這個文件），因此除了匿名用戶外本地用戶無法登錄。
方法二：
在測試Checkpoint的VPN1 R6x的時候，遇到了這個錯誤。這說明client端跟server端的連接性是沒問題。但是就是想不出為什麼，還以為是用戶名和口令錯誤呢。後來才google了一下，發現是server端的配置有問題。
檢查/etc/vsftpd/user_list和/etc/ftpusers，是這個文件/etc/vsftpd/vsftpd.conf少了一行：
代碼如下：
pam_service_name=vsftpd
$ echo ‘pam_service_name=vsftpd’ 》》/etc/vsftpd/vsftpd.conf
$ service vsftpd restart
530 error就消除了！
下面是更詳細的方法：
［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
