为什么我自己写的vsftpd.conf文件就不能登入呢?

我的系统是rh9,我嫌默认的vsftpd.conf里面东西太杂大多,于是就自己写了一个,内容如下.几乎是照着抄呀:
#Access
anonymous_enable=YES
local_enable=YES
write_enable=YES
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES

#Sercurity
anon_world_readalbe_only=YES
connect_from_port_20=YES

#Feature
xferlog_enable=YES
ls_recurse_enable=NO
ascii_download_enable=YES
async_abor_enable=YES

#performance
one_precess_model=YES
idle_session_timeout=YES

#enable for standalone mode
listen=YES
tcp_wrappers=YES

保存为vsftpd.conf后,启动service vsftpd start,成功,但是登入显示
[root@localhost root]# ftp 127.0.0.1
ftp: connect: Connection refused
ftp>
可是我只要一用默认配置文件(我原来备份过的^_^),重新service vsftpd start
马上就可以了.why,why,why???还有一个疑问,为什么他默认的vsftpd.conf只有那么区区3.X k大,而我自己写的文件却足有几百k,我在vi下写的,我后来改用gedit写也是这样.why?

是不是tcp_wrappers=YES得问题?
你的hosts.deny是不是ALL了?

检查一下你的防火墙设置。
 楼主| 发表于 2004-11-13 15:47:54 | 显示全部楼层
我没有开防火墙,也不是hosts.deny里面也没有设置任何东东,真是奇怪.默认的配置文件内容如下:
# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are very paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
#
# Allow anonymous FTP?
anonymous_enable=YES
#
# 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 icetug 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

你改动什么了?。。

你把pam取消了,不知道会不会影响。

看看服务是否启动了,虽然service说是成功了。

你看看你自己写的文件权限有没有问题!
 楼主| 发表于 2004-11-15 14:51:46 | 显示全部楼层
搞定,原来弄来半天,是这个文件没有执行权限为444.
两行的单词写错啦.
anon_world_readalbe_only=YES /*readalbe写错啦.应该 是readable
one_precess_model /*process写错啦,应该是process
idel_session_timeout=yes,写错啦,应该是个数字才对.不过我运行时已经把它注释掉啦

pam_service_name也应该是要的,只不过这个参数只是当使用匿名用户或虚拟用户的用户密码验证时指定文件所在.因为当时测试的是anon,所以也就通过啦.不过也是个隐藏的错误.
还有就是匿名用户访问one_process_model必须是NO
谢谢大家啦
pam没有影响.只用到虚拟用户的话

觉着vsftpd的安全这点很像java,pascal语法的做法.公式化,不容半点错误.很是安全!就是丧失了灵活性.
