问一个关于ftp服务器的设置问题

noodle

用的是wu-ftp，redhat7.3
远程怎么也登不上，如果在local，则可以登上，但是很慢。
linux的防火墙已经关掉，已经把shutmsg删掉。

我的ftpaccess文件如下，大家看看有什么问题

# This file controls the behavior of the wu-ftpd
# ftp server.
#
# If you're looking for a graphical frontend to
# editing it, try kwuftpd from the kdeadmin
# package.

# Don't allow system accounts to log in over ftp
# deny-uid %-99 %65534-
# deny-gid %-99 %65534-
allow-uid ftp
allow-gid ftp

# Chroot all users to their home directory by default
# (comment this out if you don't want to chroot most of your users)
guestuser *
# If you wish to allow user1 and user2 to access other
# directories, use the line below:
# realuser user1,user2


# The ftpchroot group doesn't exist by default, this
# entry is just supplied as an example.
# To chroot a user, modify the line below or create
# the ftpchroot group and add the user to it.
#
# You will need to setup the required applications
# and libraries in the root directory (set using
# guest-root).
#
# Look at the anonftp package for the files you'll need.
guestgroup ftpchroot

# User classes...
class   all   real,guest,anonymous  *

# Set this to your email address
email root@localhost

# Allow 5 mistyped passwords
loginfails 5

# Notify the users of README files at login and when
# changing to a different directory
readme  README*    login
readme  README*    cwd=*

# Messages displayed to the user
message /welcome.msg            login
message .message                cwd=*

# Allow on-the-fly compression and tarring
compress        yes             all
tar             yes             all

# Prevent anonymous users (and partially guest users)
# from executing dangerous commands
chmod           no              guest,anonymous
delete          no              anonymous
overwrite       no              anonymous
rename          no              anonymous

# Turn on logging to /var/log/xferlog
log transfers anonymous,guest,real inbound,outbound

# If /etc/shutmsg exists, don't allow logins
# see ftpshut man page
shutdown /etc/shutmsg

# Ask users to use their email address as anonymous
# password
passwd-check rfc822 warn

我也做过，ftpaccess和你的一样！不过还要修改一下/etc/xinetd.d/wu-ftpd，把这个文件的disable项改为no。这样就可以了！
不过我的配置完了，在有的机器可以访问，有的却不行。不知道为什么？难道是端口的问题！？请指教！
