There is a new version of this tutorial available for Ubuntu 18.04 (Bionic Beaver).

The Perfect Server - Ubuntu 12.04 LTS (nginx, BIND, Dovecot, ISPConfig 3) - Page 5

16 Install PureFTPd And Quota

PureFTPd and quota can be installed with the following command:

apt-get install pure-ftpd-common pure-ftpd-mysql quota quotatool

Edit the file /etc/default/pure-ftpd-common...

vi /etc/default/pure-ftpd-common

... and make sure that the start mode is set to standalone and set VIRTUALCHROOT=true:

[...]
STANDALONE_OR_INETD=standalone
[...]
VIRTUALCHROOT=true
[...]

Now we configure PureFTPd to allow FTP and TLS sessions. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

If you want to allow FTP and TLS sessions, run

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

In order to use TLS, we must create an SSL certificate. I create it in /etc/ssl/private/, therefore I create that directory first:

mkdir -p /etc/ssl/private/

Afterwards, we can generate the SSL certificate as follows:

openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem

Country Name (2 letter code) [AU]: <-- Enter your Country Name (e.g., "DE").
State or Province Name (full name) [Some-State]:
<-- Enter your State or Province Name.
Locality Name (eg, city) []:
<-- Enter your City.
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
<-- Enter your Organization Name (e.g., the name of your company).
Organizational Unit Name (eg, section) []:
<-- Enter your Organizational Unit Name (e.g. "IT Department").
Common Name (eg, YOUR name) []:
<-- Enter the Fully Qualified Domain Name of the system (e.g. "server1.example.com").
Email Address []:
<-- Enter your Email Address.

Change the permissions of the SSL certificate:

chmod 600 /etc/ssl/private/pure-ftpd.pem

Then restart PureFTPd:

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

Edit /etc/fstab. Mine looks like this (I added ,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 to the partition with the mount point /):

vi /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
/dev/mapper/server1-root /               ext4    errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0       1
# /boot was on /dev/sda1 during installation
UUID=4b58d345-1c55-4ac5-940e-7245938656a6 /boot           ext2    defaults        0       2
/dev/mapper/server1-swap_1 none            swap    sw              0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

To enable quota, run these commands:

mount -o remount /
quotacheck -avugm
quotaon -avug

 

17 Install BIND DNS Server

BIND can be installed as follows:

apt-get install bind9 dnsutils

 

18 Install Vlogger, Webalizer, And AWstats

Vlogger, webalizer, and AWstats can be installed as follows:

apt-get install vlogger webalizer awstats geoip-database

Open /etc/cron.d/awstats afterwards...

vi /etc/cron.d/awstats

... and comment out everything in that file:

#MAILTO=root

#*/10 * * * * www-data [ -x /usr/share/awstats/tools/update.sh ] && /usr/share/awstats/tools/update.sh

# Generate static reports:
#10 03 * * * www-data [ -x /usr/share/awstats/tools/buildstatic.sh ] && /usr/share/awstats/tools/buildstatic.sh

 

19 Install Jailkit

Jailkit is needed only if you want to chroot SSH users. It can be installed as follows (important: Jailkit must be installed before ISPConfig - it cannot be installed afterwards!):

apt-get install build-essential autoconf automake1.9 libtool flex bison debhelper binutils-gold
cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.14.tar.gz
tar xvfz jailkit-2.14.tar.gz
cd jailkit-2.14
./debian/rules binary

You can now install the Jailkit .deb package as follows:

cd ..
dpkg -i jailkit_2.14-1_*.deb
rm -rf jailkit-2.14*

 

20 Install fail2ban

This is optional but recommended, because the ISPConfig monitor tries to show the log:

apt-get install fail2ban

To make fail2ban monitor PureFTPd and Dovecot, create the file /etc/fail2ban/jail.local:

vi /etc/fail2ban/jail.local
[pureftpd]

enabled  = true
port     = ftp
filter   = pureftpd
logpath  = /var/log/syslog
maxretry = 3


[dovecot-pop3imap]

enabled = true
filter = dovecot-pop3imap
action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp]
logpath = /var/log/mail.log
maxretry = 5

Then create the following two filter files:

vi /etc/fail2ban/filter.d/pureftpd.conf
[Definition]
failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.*
ignoreregex =
vi /etc/fail2ban/filter.d/dovecot-pop3imap.conf
[Definition]
failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.*
ignoreregex =

Restart fail2ban afterwards:

/etc/init.d/fail2ban restart

07-06-2012: Jailkit 2.15 released

They resolved the issues:

insserv: warning: script 'K01jailkit' missing LSB tags and overrides
insserv: warning: script 'jailkit' missing LSB tags and overrides

 So the revision:

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.15.tar.gz
tar xvfz jailkit-2.15.tar.gz
cd jailkit-2.15
./debian/rules binary

cd ..
dpkg -i jailkit_2.15-1_*.deb
rm -rf jailkit-2.15*

Fail2Ban already has a pureftpd.conf file which looks like this:

# Fail2Ban configuration file
#
# Author: Cyril Jaquier
# Modified: Yaroslav Halchenko for pure-ftpd
#
# $Revision$
#
[Definition]
# Error message specified in multiple languages
__errmsg = (?:Authentication failed for user|Erreur d'authentification pour l'utilisateur)
#
# Option: failregex
# Notes.: regex to match the password failures messages in the logfile. The
#         host must be matched by a group named "host". The tag "<HOST>" can
#         be used for standard IP/hostname matching and is only an alias for
#         (?:::f{4,6}:)?(?P<host>[\w\-.^_]+)
# Values: TEXT
#
failregex = pure-ftpd(?:\[\d+\])?: \([email protected]<HOST>\) \[WARNING\] %(__errmsg)s \[.+\]\s*$
# Option:  ignoreregex
# Notes.:  regex to ignore. If this regex matches, the line is ignored.
# Values:  TEXT
#
ignoreregex = 



Dovecot also seems covered:
 
# Fail2Ban configuration file for dovcot
#
# Author: Martin Waschbuesch
#
# $Revision$
#

[Definition]

# Option:  failregex
# Notes.:  regex to match the password failures messages in the logfile. The
#          host must be matched by a group named "host". The tag "<HOST>" can
#          be used for standard IP/hostname matching and is only an alias for
#          (?:::f{4,6}:)?(?P<host>[\w\-.^_]+)
# Values:  TEXT
#
failregex = .*(?:pop3-login|imap-login):.*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.*

# Option:  ignoreregex
# Notes.:  regex to ignore. If this regex matches, the line is ignored.
# Values:  TEXT
#
ignoreregex =   
 This is on Ubuntu Server 12.04.1 LTS on 19.08.2012.

Where is this file?

By: ababneh

Hello,

 I followed this tutorial and get everything working, thank you. Just have one question. I have a folder with 15k files but the there is only 9998 files show in filezilla. I tried to locate the config file for pureftpd that contains the limit but I couldn't.  Could you please point that out?

 Thanks
