Virtual Hosting With Proftpd And MySQL

This howto is based on Virtual Hosting With Proftpd And MySQL (Incl. Quota) howto. It was adopted to work under Debian Etch.

Install MySQL And phpMyAdmin

apt-get install mysql-server mysql-client libmysqlclient15-dev phpmyadmin

Set password for mysql root user, choose your own password.

mysqladmin -u root password yourrootsqlpassword

Install Proftpd With MySQL support

apt-get install proftpd-mysql

Run proftpd from inetd or standalone? ←- standalone

Then we create an ftp group (“ftpgroup”) and user (“ftpuser”) that all our virtual users will be mapped to.

groupadd ftpgroup
useradd -s /bin/false -d /bin/null -c "proftpd user" -g ftpgroup ftpuser

Create The MySQL Database For Proftpd

Now we create a database called ftp and a MySQL user named proftpd which the proftpd daemon will use later on to connect to the ftp database:

mysql -u root -p
create database ftp;
GRANT SELECT, INSERT, UPDATE, DELETE ON ftp.* TO 'proftpd'@'localhost' IDENTIFIED BY 'password';
GRANT SELECT, INSERT, UPDATE, DELETE ON ftp.* TO 'proftpd'@'localhost.localdomain' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

Replace the string password with whatever password you want to use for the MySQL user proftpd. Still on the MySQL shell, we create the database tables we need:

USE ftp;

CREATE TABLE ftpgroup (
groupname varchar(16) NOT NULL default '',
gid smallint(6) NOT NULL default '5500',
members varchar(16) NOT NULL default '',
KEY groupname (groupname)
) TYPE=MyISAM COMMENT='ProFTP group table';

CREATE TABLE ftpquotalimits (
name varchar(30) default NULL,
quota_type enum('user','group','class','all') NOT NULL default 'user',
per_session enum('false','true') NOT NULL default 'false',
limit_type enum('soft','hard') NOT NULL default 'soft',
bytes_in_avail int(10) unsigned NOT NULL default '0',
bytes_out_avail int(10) unsigned NOT NULL default '0',
bytes_xfer_avail int(10) unsigned NOT NULL default '0',
files_in_avail int(10) unsigned NOT NULL default '0',
files_out_avail int(10) unsigned NOT NULL default '0',
files_xfer_avail int(10) unsigned NOT NULL default '0'
) TYPE=MyISAM;

CREATE TABLE ftpquotatallies (
name varchar(30) NOT NULL default '',
quota_type enum('user','group','class','all') NOT NULL default 'user',
bytes_in_used int(10) unsigned NOT NULL default '0',
bytes_out_used int(10) unsigned NOT NULL default '0',
bytes_xfer_used int(10) unsigned NOT NULL default '0',
files_in_used int(10) unsigned NOT NULL default '0',
files_out_used int(10) unsigned NOT NULL default '0',
files_xfer_used int(10) unsigned NOT NULL default '0'
) TYPE=MyISAM;

CREATE TABLE ftpuser (
id int(10) unsigned NOT NULL auto_increment,
userid varchar(32) NOT NULL default '',
passwd varchar(32) NOT NULL default '',
uid smallint(6) NOT NULL default '5500',
gid smallint(6) NOT NULL default '5500',
homedir varchar(255) NOT NULL default '',
shell varchar(16) NOT NULL default '/sbin/nologin',
count int(11) NOT NULL default '0',
accessed datetime NOT NULL default '0000-00-00 00:00:00',
modified datetime NOT NULL default '0000-00-00 00:00:00',
PRIMARY KEY (id),
UNIQUE KEY userid (userid)
) TYPE=MyISAM COMMENT='ProFTP user table';

quit;

As you may have noticed, with the quit; command we have left the MySQL shell and are back on the Linux shell.

BTW, (I'm suggesting that the hostname of your ftp server system is server1.example.com) you can access phpMyAdmin over http://server1.example.com/phpmyadmin/ (you can use the IP address instead of server1.example.com) in a browser and log in as proftpd. Then you can have a look at the database. Later on you can use phpMyAdmin to administrate your Proftpd server.

Configure Proftpd

Open /etc/proftpd.conf and add the following lines at the bottom to it. Make sure that you replace the string password with the real password for the MySQL user proftpd in the line SQLConnectInfo!

DefaultRoot ~


# The passwords in MySQL are encrypted using CRYPT
SQLAuthTypes            Plaintext Crypt
SQLAuthenticate         users* groups*


# used to connect to the database

# Here we tell ProFTPd the names of the database columns in the "usertable"
# we want it to interact with. Match the names with those in the db
SQLUserInfo     ftpuser userid passwd uid gid homedir shell

# Here we tell ProFTPd the names of the database columns in the "grouptable"
# we want it to interact with. Again the names match with those in the db
SQLGroupInfo    ftpgroup groupname gid members

# set min UID and GID - otherwise these are 999 each
SQLMinID        500

# create a user's home directory on demand if it doesn't exist

# Update count every time user logs in

SQLNamedQuery modified UPDATE "modified=now() WHERE userid='%u'" ftpuser

# User quotas

SQLNamedQuery get-quota-limit SELECT "name, quota_type, per_session, limit_type, bytes_in_avail, bytes_out_avail, bytes_xfer_avail, files_in_avail, files_out_avail, files_xfer_avail FROM ftpquotalimits WHERE name = '%{0}' AND quota_type = '%{1}'"

SQLNamedQuery get-quota-tally SELECT "name, quota_type, bytes_in_used, bytes_out_used, bytes_xfer_used, files_in_used, files_out_used, files_xfer_used FROM ftpquotatallies WHERE name = '%{0}' AND quota_type = '%{1}'"

SQLNamedQuery update-quota-tally UPDATE "bytes_in_used = bytes_in_used + %{0}, bytes_out_used = bytes_out_used + %{1}, bytes_xfer_used = bytes_xfer_used + %{2}, files_in_used = files_in_used + %{3}, files_out_used = files_out_used + %{4}, files_xfer_used = files_xfer_used + %{5} WHERE name = '%{6}' AND quota_type = '%{7}'" ftpquotatallies

SQLNamedQuery insert-quota-tally INSERT "%{0}, %{1}, %{2}, %{3}, %{4}, %{5}, %{6}, %{7}" ftpquotatallies

QuotaLimitTable sql:/get-quota-limit
QuotaTallyTable sql:/get-quota-tally/update-quota-tally/insert-quota-tally

RootLogin off

SQLNamedQuery gettally  SELECT "ROUND((bytes_in_used/1048576),2) FROM ftpquotatallies WHERE name='%u'"
SQLNamedQuery getlimit  SELECT "ROUND((bytes_in_avail/1048576),2) FROM ftpquotalimits WHERE name='%u'"
SQLNamedQuery getfree   SELECT "ROUND(((ftpquotalimits.bytes_in_avail-ftpquotatallies.bytes_in_used)/1048576),2) FROM ftpquotalimits,ftpquotatallies WHERE ftpquotalimits.name = '%u' AND ftpquotatallies.name = '%u'"

SQLShowInfo   LIST    "226" "Used %{gettally}MB from %{getlimit}MB. You have %{getfree}MB available space."

Open /etc/proftpd/modules.conf and uncomment 'LoadModule mod_sql_postgres.c':

#LoadModule mod_sql_postgres.c

Restart Proftpd:

/etc/init.d/proftpd restart

Populate The Database And Test

To populate the database you can use the MySQL shell. First we create an entry in the table ftpgroup. It contains the groupname, the groupid and the username of the ftp group/user we created at the end of step two. You can get the UID and GUID with:

id ftupser
mysql -u root -p
USE ftp;
INSERT INTO `ftpgroup` (`groupname`, `gid`, `members`) VALUES ('ftpgroup', 1001, 'ftpuser');

Now we are done with the table ftpgroup. We do not have to create further entries here. Whenever you create a new virtual ftp user, you do this in the tables ftpquotalimits and ftpuser. So let us create our first user (we are still on the MySQL shell):

INSERT INTO `ftpquotalimits` (`name`, `quota_type`, `per_session`, `limit_type`, `bytes_in_avail`, `bytes_out_avail`, `bytes_xfer_avail`, `files_in_avail`, `files_out_avail`, `files_xfer_avail`) VALUES ('exampleuser', 'user', 'true', 'hard', 15728640, 0, 0, 0, 0, 0);
INSERT INTO `ftpuser` (`id`, `userid`, `passwd`, `uid`, `gid`, `homedir`, `shell`, `count`, `accessed`, `modified`) VALUES (1, 'exampleuser', 'secret', 1001, 1001, '/home/ftp/ju.edu.et/exampleuser', '/sbin/nologin', 0, '', '');
quit;

(Do not forget to replace the groud- and userid 1001 appropriately in the last INSERT statement if you are using other values than in this tutorial!)

Now open your FTP client program on your work station (something like WS_FTP or SmartFTP if you are on a Windows system) and try to connect. As hostname you use server1.example.com (or the IP address of the system), the username is exampleuser, and the password is secret.

E.g. on Debian you can install ncftp, and use that program to connect to the ftp server (server1.example.com in this case)

apt-get install ncftp
ncftp -u exampleuser server1.example.com

If you are able to connect - congratulations! If not, something went wrong.

Now, if you run

ls -l /home/ftp/*

you should see that the directory /home/ftp/ju.edu.et/exampleuser (exampleuser's home directory) has been automatically created, and it belongs to ftpuser and ftpgroup (the user/group we created at the end of step two).

To leave the MySQL shell, type

quit;
