菜鸟ubuntu8.04桌面版配置vsftp+mysql+pam 无法使用

[yinsuntoday]

我是根据下面配置：
因为工作需要安装一个ftp服务器，需要使用多ftp用户并能够方便的管理ftp用户。于是使用vsftp+mysql+pam的组合，在mysql中进行用户管理。特写了这么一个记录安装过程的文章，提供给大家一起讨论。

1.安装vsftpd

代码:
sudo apt-get install vsftpd


2.创建guest用户

vsftpd安装的时候会自动安转一个ftp用户，在passwd中删除

代码:
sudo useradd real

代码:
sudo passwd real


代码:
sudo vim /etc/passwd


3.设置mysql数据库和用户权限

在phpmyadmin中建立vsftp数据库 vsftp用户
安装mysql
设置mysql权限
sudo apt-get install mysql-server
设置mysql密码 sunday

mysql>create database vsftpid;
　　mysql>use vsftpid;
　　mysql>create table vsftp(name char(16) binary,passwd char(16) binary);
　　mysql>insert into vsftp (name,passwd) values ('real',password('real'));
　　
　　
并授权限，并设置密码
mysql>grant select on vsftpid.vsftp to real_root@localhost identified by 'real';

+------+------------------+
| name | passwd |
+------+------------------+
| real | *CD538865C03D379 |
+------+------------------+
1 row in set (0.00 sec)

mysql 设置成功

4.设置MySQL的PAM验证

安装libpam-mysql

代码:
sudo apt-get install libpam-mysql


要设置vsftpd的PAM验证文件

代码:
sudo cp /usr/share/doc/vsftpd/EXAMPLE/VIRTUAL_USERS/vsftpd.pam /etc/pam.d/vsftpd

把内容替换为如下：

代码:
auth required /lib/security/pam_mysql.so user=real_root passwd=real host=localhost db=vsftpid table=vsftp usercolumn=name passwdcolumn=passwd crypt=2
account required /lib/security/pam_mysql.so user=real_root passwd=real host=localhost db=vsftpid table=vsftp usercolumn=name passwdcolumn=passwd crypt=2

5.设置vsftpd.conf

代码:
# 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.
#
#
# Run standalone? vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
listen=YES
#
# Run standalone with IPv6?
# Like the listen parameter, except vsftpd will listen on an IPv6 socket
# instead of an IPv4 one. This parameter and the listen parameter are mutually
# exclusive.
#listen_ipv6=YES
#
# 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
#
guest_enable=YES
guest_username=real
user_config_dir=/etc/vsftpd
# 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 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 restrict local users to their home directories. See the FAQ for
# the possible risks in this before using chroot_local_user or
# chroot_list_enable below.
chroot_local_user=YES
#
# 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
#
#
# Debian customization
#
# Some of vsftpd's settings don't fit the Debian filesystem layout by
# default. These settings are more Debian-friendly.
#
# This option should be the name of a directory which is empty. Also, the
# directory should not be writable by the ftp user. This directory is used
# as a secure chroot() jail at times vsftpd does not require filesystem
# access.
secure_chroot_dir=/home/ftp
#
# This string is the name of the PAM service vsftpd will use.
pam_service_name=vsftpd
#
# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
# This option specifies the location of the RSA key to use for SSL
# encrypted connections.
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

6.虚拟用户目录的权限改为只能由real操作：

代码:
sudo chown real.real /home/ftp/real
sudo chmod 755 /home /ftp/real


代码:
sudo /etc/init.d/vsftpd restart

连接后显示为
USER real

331 Please specify the password.
PASS xxxx
530 Login incorrect.
正在断开与站点 192.168.4.9 的连接

各位大侠 是什么问题？？？？？？？？？

你在论坛搜索下吧，曾经写过一个帖子的

[hubert_star]

个人感觉pureftpd比vsftpd要好用很多，而且它的very secure没看到secure在哪

[str263]

mysql>create database vsftpdid;

auth required /lib/security/pam_mysql.so user=real_root passwd=real host=localhost db=vsftpid table=vsftp usercolumn=name passwdcolumn=passwd crypt=2

还是无法连接

[str263]

account required /lib/security/pam_mysql.so user=real_rootl passwd=real host=localhost db=vsftpid table=vsftp usercolumn=name passwdcolumn=passwd crypt=2

[yinsuntoday]

account required /lib/security/pam_mysql.so user=real_rootl passwd=real host=localhost db=vsftpid table=vsftp usercolumn=name passwdcolumn=passwd crypt=2
我更改了但还不行

[wangzi6hao]

create table vsftp(name char(16) binary,passwd char(16) binary);
这一句的问题.
用了crypt=2 的话,mysql生成的密码会有48位长.
而passwd char(16)只有16位长,你怎么验证,密码都会是错的.
刚试出来,网上很多这样转贴的人我都怀疑有没有自己测试.
晕死了.

[angelus]

恩，楼上说的很有可能，当时我测试用的crypt=0，没有问题
用2的时候用的图形工具，没有通过，还以为是工具的问题！
不过mysql的passwd()加密没有那么多位吧

正好是16位，创建的时候使用20或许更合适
