Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Debian Etch - Page 2

5 Configure PureFTPd

Edit /etc/pure-ftpd/db/mysql.conf. It should look like this:

cp /etc/pure-ftpd/db/mysql.conf /etc/pure-ftpd/db/mysql.conf_orig
cat /dev/null > /etc/pure-ftpd/db/mysql.conf
vi /etc/pure-ftpd/db/mysql.conf

MYSQLSocket      /var/run/mysqld/mysqld.sock
#MYSQLServer     localhost
#MYSQLPort       3306
MYSQLUser       pureftpd
MYSQLPassword   ftpdpass
MYSQLDatabase   pureftpd
#MYSQLCrypt md5, cleartext, crypt() or password() - md5 is VERY RECOMMENDABLE uppon cleartext
MYSQLCrypt      md5
MYSQLGetPW      SELECT Password FROM ftpd WHERE User="\L" AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MYSQLGetUID     SELECT Uid FROM ftpd WHERE User="\L" AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MYSQLGetGID     SELECT Gid FROM ftpd WHERE User="\L"AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MYSQLGetDir     SELECT Dir FROM ftpd WHERE User="\L"AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MySQLGetBandwidthUL SELECT ULBandwidth FROM ftpd WHERE User="\L"AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MySQLGetBandwidthDL SELECT DLBandwidth FROM ftpd WHERE User="\L"AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MySQLGetQTASZ   SELECT QuotaSize FROM ftpd WHERE User="\L"AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")
MySQLGetQTAFS   SELECT QuotaFiles FROM ftpd WHERE User="\L"AND status="1" AND (ipaccess = "*" OR ipaccess LIKE "\R")

Make sure that you replace the string ftpdpass with the real password for the MySQL user pureftpd in the line MYSQLPassword! Please note that we use md5 as MYSQLCrypt method, which means we will store the users' passwords as an MD5 string in the database which is far more secure than using plain text passwords!

Then create the file /etc/pure-ftpd/conf/ChrootEveryone which simply contains the string yes:

echo "yes" > /etc/pure-ftpd/conf/ChrootEveryone

This will make PureFTPd chroot every virtual user in his home directory so he will not be able to browse directories and files outside his home directory.

Also create the file /etc/pure-ftpd/conf/CreateHomeDir which again simply contains the string yes:

echo "yes" > /etc/pure-ftpd/conf/CreateHomeDir

This will make PureFTPd create a user's home directory when the user logs in and the home directory does not exist yet.

Now we must configure PureFTPd as a standalone daemon (it is currently controlled by inetd). To do this, we open /etc/default/pure-ftpd-common and change the value of the parameter STANDALONE_OR_INETD to standalone:

vi /etc/default/pure-ftpd-common

# Configuration for pure-ftpd
# (this file is sourced by /bin/sh, edit accordingly)

# STANDALONE_OR_INETD
# valid values are "standalone" and "inetd".
# Any change here overrides the setting in debconf.
STANDALONE_OR_INETD=standalone

# VIRTUALCHROOT:
# whether to use binary with virtualchroot support
# valid values are "true" or "false"
# Any change here overrides the setting in debconf.
VIRTUALCHROOT=false

# UPLOADSCRIPT: if this is set and the daemon is run in standalone mode,
# pure-uploadscript will also be run to spawn the program given below
# for handling uploads. see /usr/share/doc/pure-ftpd/README.gz or
# pure-uploadscript(8)

# example: UPLOADSCRIPT=/usr/local/sbin/uploadhandler.pl
UPLOADSCRIPT=

# if set, pure-uploadscript will spawn $UPLOADSCRIPT running as the
# given uid and gid
UPLOADUID=
UPLOADGID=

Next, we modify /etc/inetd.conf and comment out the ftp line:

vi /etc/inetd.conf

[...]
#ftp     stream  tcp     nowait  root    /usr/sbin/tcpd /usr/sbin/pure-ftpd-wrapper
[...]

Afterwards, we restart Inetd and PureFTPd:

/etc/init.d/openbsd-inetd restart
/etc/init.d/pure-ftpd-mysql restart

 

6 Populate The Database And Test

To populate the database you can use the MySQL shell:

mysql -u root -p

USE pureftpd;

Now we create the user exampleuser with the status 1 (which means his ftp account is active), the password secret (which will be stored encrypted using MySQL's MD5 function), the UID and GID 2001 (use the userid and groupid of the user/group you created at the end of step two!), the home directory /home/www.example.com, an upload and download bandwidth of 100 KB/sec. (kilobytes per second), and a quota of 50 MB:

INSERT INTO `ftpd` (`User`, `status`, `Password`, `Uid`, `Gid`, `Dir`, `ULBandwidth`, `DLBandwidth`, `comment`, `ipaccess`, `QuotaSize`, `QuotaFiles`) VALUES ('exampleuser', '1', MD5('secret'), '2001', '2001', '/home/www.example.com', '100', '100', '', '*', '50', '0');

quit;

Now open your FTP client program on your work station (something like WS_FTP or SmartFTP if you are on a Windows system or gFTP on a Linux desktop) 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.

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

Now, if you run

ls -l /home

you should see that the directory /home/www.example.com (exampleuser's home directory) has been automatically created, and it is owned by ftpuser and ftpgroup (the user/group we created at the end of step two):

server1:/etc/default# ls -l /home
total 8
drwxr-xr-x 2 administrator administrator 4096 2007-04-23 14:25 administrator
drwxr-xr-x 2 ftpuser       ftpgroup      4096 2007-04-23 17:26 www.example.com

Of course, both pureftp and ProFTP support using LDAP as the backend (which may provide a better backend store, depending on what other features you are providing to your users).

There´s no need to recompile, TLS is supported in the apt-get package for Debian.

Instructions:

1) To support SSL/TLS, the OpenSSL library must already be installed on your system. This is a common requirement so your operating system probably already ships with it, but you never now

apt-get install openssl

2) Now you need an SSL Certificate, you can buy one from a certified authority or you can create your own certificate. To create a self-signed certificate, you can use the following commands :

mkdir -p /etc/ssl/private

openssl req -x509 -nodes -newkey rsa:1024 -keyout \
  /etc/ssl/private/pure-ftpd.pem \
  -out /etc/ssl/private/pure-ftpd.pem

chmod 600 /etc/ssl/private/*.pem

3) Now we add TLS support in the configuration files

echo 1 > /etc/pure-ftpd/conf/TLS

4) Finally we restart the daemon, the output should look like this:

/etc/init.d/pure-ftpd-mysql restart
Restarting ftp server: Running: /usr/sbin/pure-ftpd-mysql -l mysql:/etc/pure-ftpd/db/mysql.conf -l pam -j -Y 1 -A -E -O clf:/var/log/pure-ftpd/transfer.log -u 1000 -B

(the -Y option enables the TLS Support)

5) If everything worked fine , now we have a TLS capable pure-ftpd server. When some client connects to the server trough TLS you should see something like this in the log files:

Jun 22 17:35:48 console pure-ftpd: (?@192.168.251.4) [INFO] SSL/TLS: Enabled TLSv1/SSLv3 with AES256-SHA, 256 secret bits cipher

 

Hope this helps!

BTW: the guide was great, everything worked fine from scratch! :-)
