pam＋vsftpd創建虛擬用戶！內網完全正常，外網無法訪問
pam＋vsftpd創建虛擬用戶 這教程網上多的是，但我無論試哪種方法，
外網始終出錯，如圖：
看我/etc/vsftpd/vsftpd.conf配置文件：#
Example config file /etc/vsftpd/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
#
# The target log file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
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
#
# The name of log file when xferlog_enable=YES and xferlog_std_format=YES
# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log
xferlog_file=/game/log/xferlog
#
# Switches between logging into vsftpd_log_file and xferlog_file files.
# NO writes to vsftpd_log_file, YES to xferlog_file
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 on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
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
#
# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd whith two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
#local_root=/game/xfen
anon_root=/mp3
local_max_rate=256000
chroot_local_user=yes
listen_port=21
guest_enable=YES
guest_username=xfen
user_config_dir=/etc/vsftpd/user_config_dir
pasv_enable=yes
pasv_min_port=50000
pasv_max_port=50009
#pasv_address=
#max_clients=300：設置FTP伺服器最大接入客戶端數為300個
#max_per_ip=10：設置每個IP地址最大連接數為10個
#pasv_addr_resolve=YES
#accept_timeout=60 #接受建立聯機的超時設定，單位秒。
#connect_timeout=60 #客戶端空閑的超時時間。
虛擬用戶lan配置文件：
#local_max_rate=256000
download_enable=yes
local_root=/game/xfen/lan
#write_enable=YES
anon_world_readable_only=no
anon_upload_enable=YES
anon_mkdir_write_enable=yes
anon_other_write_enable=yes
anon_max_rate=5000000：限定傳輸速率為50KB/s
各位高人幫我多多，謝謝！

netstat -tnl 看看，還有你又外網ip嗎？

1，樓主SELinux是不是關了。
2，日誌看看有什麼信息，對了vsftpd有兩種日誌，都看看。
另外，可以在客戶端:
telnet IP 21
測試一下，是否可以連接。

回復 #1 xfen 的帖子
不想看了
《解決方案》
檢查下ftp的日誌.

1.SELinux是關掉了
2. 我查看/var/log/xferlog xferlog.1 xferlog.2
和 /var/log/vsftpd.log vsftpd.log.1 vsftpd.log.2
未發現有錯誤的提示之類的
是否是這兩種文件

恩 一個是連接登錄日誌 一個下載上傳日誌
日誌沒有錯誤。
那就只好：
1、tcpdump或者wireshark抓包
2、telnet IP PORT 連接后使用協議指令測試

關注，不知道問題解決了沒。現在也遇到同樣的問題，頂一下。
