    RootLogin on<br>
<br>
如何禁止某个地址访问ftp<br>
比如禁止10.1.1网段的机器访问ftp,可以这么设置<br>
<br>
    &lt;Limit LOGIN&gt;<br>
    Order deny,allow<br>
    Deny from 10.1.1.<br>
    Allow from all<br>
    &lt;/Limit&gt;<br>
<br>
<br>
虚拟ftp的建立,一般用于一台ftp服务器有好多ip地址,或者ftp用不同的端口,基本设置语法是:<br>
<br>
比如我们要做一个端口是5555的ftp服务器:<br>
<br>
    &lt;VirtualHost 210.51.0.124&gt;<br>
    ServerName "Frank FTP Server"<br>
    Port 5555<br>
    ...<br>
    &lt;Directory 目录&gt;<br>
    ...<br>
    &lt;Limit 动作&gt;<br>
    ...<br>
    &lt;/Limit&gt;<br>
    ...<br>
    &lt;/Directory&gt;<br>
    &lt;/VirtualHost&gt;<br>
<br>
<br>
至于虚拟主机中的其他设置跟我以前讲的基本差不多<br>
<br>
上传/下载比率设置,我想用过Serv_U的朋友一定知道这个功能的使用,我们这里让proftp也实现这个功能。<br>
要实现功能注意编译的时候加入ratio模块,否则proftp默认是不支持,假设有个帐户ftp1的ftp目录在/home/kaoyan ,然后我们设置ftp1的上传/下载比率是1:2(即上传1M,就可以下载2M)<br>
<br>
    touch /home/kaoyan/ratio.dat<br>
    touch /home/kaoyan/ratio.tmp<br>
    chmod -R 666 /home/kaoyan<br>
<br>
在proftpd.conf设置如下<br>
<br>
    Ratios on<br>
    SaveRatios on<br>
    RatioFile /home/kaoyan/ratio.dat<br>
    RatioTempFile /home/kaoyan/ratio.tmp<br>
<br>
在相应的设置项里添加<br>
<br>
    UserRatio ftp1 0 0 2 1000<br>
<br>
#UserRatio "使用者帐户" fileratio filequota byteratio bytequota<br>
#  fileratio :以文件为基础的比率,通常不限制,故为 0<br>
#  filequota :预设置能下载多少文件,不限制时为 0<br>
#  byteratio :就是上传/下载的比例,如果数字为2,表示1:2<br>
#  bytequota :预设置能下载多少 KBytes 的文件<br>
#上面设置的就是1:2的比率,默认只允许下载1M的文件<br>
<br>
ok,重启一下,以后ftp1就可以启用上传/下载比率了<br>
<br>
<br>
proftpd学习笔记(四)<br>
<br>
今天我们讲proftp+mysql+quota的应用,我想大家最期待的就是这个了吧<br>
<br>
1.首先我们建立相应的用户和用户组<br>
<br>
    groupadd -g 5500 ftpgroup<br>
    adduser -u 5500 -s /bin/false -d /bin/null -c "proftpd user" -g ftpgroup ftpuser<br>
<br>
2.操作数据库<br>
<br>
    mysql mysql -uroot -ppassword<br>
    create database ftpdb<br>
    grant select, update on ftpdb.* to proftpd@localhost identified by 'password'<br>
<br>
    use ftpdb<br>
<br>
<br>
    CREATE TABLE `ftpgroup` (<br>
    `groupname` varchar(16) NOT NULL default '',<br>
    `gid` smallint(6) NOT NULL default '5500',<br>
    `members` varchar(16) NOT NULL default '',<br>
    KEY `groupname` (`groupname`)<br>
    ) TYPE=MyISAM COMMENT='ProFTP group table';<br>
<br>
    INSERT INTO `ftpgroup` VALUES ('ftpgroup', 5500, 'ftpuser');<br>
<br>
    CREATE TABLE `ftpquotalimits` (<br>
    `name` varchar(30) default NULL,<br>
    `quota_type` enum('user','group','class','all') NOT NULL default 'user',<br>
    `per_session` enum('false','true') NOT NULL default 'false',<br>
    `limit_type` enum('soft','hard') NOT NULL default 'soft',<br>
    `bytes_in_avail` float NOT NULL default '0',<br>
    `bytes_out_avail` float NOT NULL default '0',<br>
    `bytes_xfer_avail` float NOT NULL default '0',<br>
    `files_in_avail` int(10) unsigned NOT NULL default '0',<br>
    `files_out_avail` int(10) unsigned NOT NULL default '0',<br>
    `files_xfer_avail` int(10) unsigned NOT NULL default '0'<br>
    ) TYPE=MyISAM;<br>
<br>
    CREATE TABLE `ftpquotatallies` (<br>
    `name` varchar(30) NOT NULL default '',<br>
    `quota_type` enum('user','group','class','all') NOT NULL default 'user',<br>
    `bytes_in_used` float NOT NULL default '0',<br>
    `bytes_out_used` float NOT NULL default '0',<br>
    `bytes_xfer_used` float NOT NULL default '0',<br>
    `files_in_used` int(10) unsigned NOT NULL default '0',<br>
    `files_out_used` int(10) unsigned NOT NULL default '0',<br>
    `files_xfer_used` int(10) unsigned NOT NULL default '0'<br>
    ) TYPE=MyISAM;<br>
<br>
    CREATE TABLE `ftpuser` (<br>
    `id` int(10) unsigned NOT NULL auto_increment,<br>
    `userid` varchar(32) NOT NULL default '',<br>
    `passwd` varchar(32) NOT NULL default '',<br>
    `uid` smallint(6) NOT NULL default '5500',<br>
    `gid` smallint(6) NOT NULL default '5500',<br>
    `homedir` varchar(255) NOT NULL default '',<br>
    `shell` varchar(16) NOT NULL default '/sbin/nologin',<br>
    `count` int(11) NOT NULL default '0',<br>
    `accessed` datetime NOT NULL default '0000-00-00 00:00:00',<br>
    `modified` datetime NOT NULL default '0000-00-00 00:00:00',<br>
    PRIMARY KEY (`id`)<br>
    ) TYPE=MyISAM COMMENT='ProFTP user table' ;<br>
<br>
注意这里大家根据实际情况填写自己数据库的用户名和密码,如果大家对数据库操作不熟悉的话,不妨可以用phpmyadmin来操作。<br>
<br>
3.配置proftp文件<br>
<br>
    ServerName "Frank's FTP Server" ServerType standalone DefaultServer on<br>
<br>
    Port 21<br>
<br>
    Umask 022<br>
<br>
    MaxInstances 30<br>
    MaxLoginAttempts 3<br>
<br>
    User nobody<br>
    Group nobody<br>
<br>
    MaxHostsPerUser 1 "Sorry, you may not connect more than one time."<br>
    MaxClientsPerUser 2 "Only one such user at a time."<br>
    MaxClientsPerHost 3 "Sorry, you may not connect more than one time."<br>
<br>
    RootLogin off<br>
    RequireValidShell off<br>
    TimeoutStalled 10<br>
    MaxClients 10<br>
    AllowForeignAddress on<br>
    AllowStoreRestart on<br>
    ServerIdent off<br>
    DefaultRoot ~ ftpgroup<br>
<br>
    SQLAuthTypes Backend Plaintext<br>
    #Backend表示用户认证方式为MySQL数据库的认证方式<br>
    #Plaintext表示明文认证方式,排在最前面的为最先使用的方式<br>
    SQLAuthenticate users* groups*<br>
<br>
    # databasename@host database_user user_password<br>
    SQLConnectInfo ftpdb@localhost proftpd password<br>
    SQLUserInfo ftpuser userid passwd uid gid homedir shell<br>
    SQLGroupInfo ftpgroup groupname gid members<br>
    SQLHomedirOnDemand on<br>
    #如果用户主目录不存在,则系统会根据此用户在用户数据表中的homedir字段的值新建一个目录<br>
    # Update count every time user logs in<br>
    SQLLog PASS updatecount<br>
    SQLNamedQuery updatecount UPDATE "count=count+1,accessed=now() WHERE userid='%u'" ftpuser<br>
    # Update modified everytime user uploads or deletes a file<br>
    SQLLog STOR,DELE modified<br>
    SQLNamedQuery modified UPDATE "modified=now() WHERE userid='%u'" ftpuser<br>
<br>
    QuotaEngine on<br>
    QuotaDirectoryTally on<br>
    QuotaDisplayUnits Mb<br>
    QuotaShowQuotas on<br>
    QuotaLog "/var/log/quota"<br>
    SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, bytes_out_avai<br>
    l, bytes_xfer_avail, files_in_avail, files_out_avail, files_xfer_avail FROM ftpquotalimits WHERE name = '%{0}'<br>
    AND quota_type = '%{1}'"<br>
<br>
    SQLNamedQuery get-quota-tally SELECT "name, quota_type, bytes_in_used, bytes_out_used, bytes_xfer_used, files_i<br>
    n_used, files_out_used, files_xfer_used FROM ftpquotatallies WHERE name = '%{0}' AND quota_type = '%{1}'"<br>
<br>
    SQLNamedQuery update-quota-tally UPDATE "bytes_in_used = bytes_in_used + %{0}, bytes_out_used = bytes_out_used<br>
    + %{1}, bytes_xfer_used = bytes_xfer_used + %{2}, files_in_used = files_in_used + %{3}, files_out_used = files_<br>
    out_used + %{4}, files_xfer_used = files_xfer_used + %{5} WHERE name = '%{6}' AND quota_type = '%{7}'" ftpquota<br>
    tallies<br>
<br>
    SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" ftpquotatallies<br>
<br>
    QuotaLimitTable sql:/get-quota-limit<br>
    QuotaTallyTable sql:/get-quota-tally/update-quota-tally/insert-quota-tally<br>
<br>
<br>
ok,就这么简单,重启一下proftp服务就已经能使用proftp+mysql+quota的功能<br>
<br>
我们可以在数据库ftpuser添加一个虚拟用户,<br>
<br>
    INSERT INTO `ftpuser` VALUES (1, 'test', 'ftppasswd', 5500, 5500, '/home/test', '/sbin/nologin');<br>
<br>
大家可以在phpmyadmin里直接操作添加一个用户,相信不用我教大家怎么添加吧:)<br>
<br>
如果你想设置quota,只要在ftpquotalimits表里设置一下就行了,这个表里的各个参数分别代表:<br>
<br>
    quotalimits表<br>
<br>
    name: - 用户帐号<br>
    quota type: - user, group, class, all (we use user)<br>
    per_session: - true or false (we use true)<br>
    limit_type: - 硬限制 or 软限制 (我们一般用硬限制)<br>
    bytes_in_avail: - 允许上传的字节数<br>
    bytes_out_avail: - 允许下载的字节数<br>
    bytes_xfer_avail: - 允许传输的字节数(包括上传/下载)<br>
    files_in_avail: - 允许上传的文件数<br>
    files_out_avail: - 允许下载的文件数<br>
    files_xfer_avail: - 允许传输的文件数(包括上传/下载)<br>
<br>
老实说用mysql和quota模块来验证用户和设置磁盘限额,但我总觉得还是不够完善,因为在这个方法中,数据库表里还没有相应的权限的字段,所以说相应用户的权限还是得用实际得用户即mysql对应得uid和gid来控制权限,那天要是mysql数据库也能完全控制权限就好了。<br>
<br>
大家如果觉得格式拷贝的时候可能会出错的话,不妨直接下载我的配置文件和数据库表<br>
<br>
下载&lt;a href=http://www.5ilinux.com/download/proftpd.conf&gt;proftpd.conf&lt;/a&gt;<br>
下载&lt;a href=http://www.5ilinux.com/download/ftpdb.sql&gt;ftpdb.sql&lt;/a&gt;<br>
只是我的数据库表里对应的uid和gid都是5500,大家可根据自己的情况修改:)注意消化哦。<br>
<br>
这个春节一直在学习proftp,终于可以松口气了,希望我的学习笔记可以对一些想学习proftp的朋友有所帮助,请多交流
