17 Install BIND

We can install BIND as follows:

yum -y install bind bind-utils

Next open /etc/sysconfig/named...

vi /etc/sysconfig/named

... and make sure that the ROOTDIR=/var/named/chroot line is comment out:

# BIND named process options
# ~~~~~~~~~~~~~~~~~~~~~~~~~~
# Currently, you can use the following options:
#
# ROOTDIR="/var/named/chroot"  --  will run named in a chroot environment.
#                            you must set up the chroot environment
#                            (install the bind-chroot package) before
#                            doing this.
#       NOTE:
#         Those directories are automatically mounted to chroot if they are
#         empty in the ROOTDIR directory. It will simplify maintenance of your
#         chroot environment.
#          - /var/named
#          - /etc/pki/dnssec-keys
#          - /etc/named
#          - /usr/lib64/bind or /usr/lib/bind (architecture dependent)
#
#         Those files are mounted as well if target file doesn't exist in
#         chroot.
#          - /etc/named.conf
#          - /etc/rndc.conf
#          - /etc/rndc.key
#          - /etc/named.rfc1912.zones
#          - /etc/named.dnssec.keys
#          - /etc/named.iscdlv.key
#
#       Don't forget to add "$AddUnixListenSocket /var/named/chroot/dev/log"
#       line to your /etc/rsyslog.conf file. Otherwise your logging becomes
#       broken when rsyslogd daemon is restarted (due update, for example).
#
# OPTIONS="whatever"     --  These additional options will be passed to named
#                            at startup. Don't add -t here, use ROOTDIR instead.
#
# KEYTAB_FILE="/dir/file"    --  Specify named service keytab file (for GSS-TSIG)
#
# DISABLE_ZONE_CHECKING  -- By default, initscript calls named-checkzone
#                           utility for every zone to ensure all zones are
#                           valid before named starts. If you set this option
#                           to 'yes' then initscript doesn't perform those
#                           checks.

Make a backup of the existing /etc/named.conf file and create a new one as follows:

cp /etc/named.conf /etc/named.conf_bak
cat /dev/null > /etc/named.conf
vi /etc/named.conf

//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
options {
        listen-on port 53 { any; };
        listen-on-v6 port 53 { any; };
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        allow-query     { any; };
        recursion yes;
};
logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
zone "." IN {
        type hint;
        file "named.ca";
};
include "/etc/named.conf.local";

Create the file /etc/named.conf.local that is included at the end of /etc/named.conf (/etc/named.conf.local will later on get populated by ISPConfig if you create DNS zones in ISPConfig):

touch /etc/named.conf.local

Then we create the startup links and start BIND:

chkconfig --levels 235 named on
/etc/init.d/named start

 

18 Install Webalizer, And AWStats

Webalizer and AWStats can be installed as follows:

yum -y install webalizer awstats perl-DateTime-Format-HTTP perl-DateTime-Format-Builder

 

19 Install Jailkit

Jailkit is used to chroot SSH users and cronjobs. It can be installed as follows (important: Jailkit must be installed before ISPConfig - it cannot be installed afterwards!):

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.17.tar.gz
tar xvfz jailkit-2.17.tar.gz
cd jailkit-2.17
./configure
make
make install
cd ..
rm -rf jailkit-2.17*

 

20 Install fail2ban

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

yum -y install fail2ban

We must configure fail2ban to log to the log file /var/log/fail2ban.log because this is the log file that is monitored by the ISPConfig Monitor module. Open /etc/fail2ban/fail2ban.conf...

vi /etc/fail2ban/fail2ban.conf

... and comment out the logtarget = SYSLOG line and add logtarget = /var/log/fail2ban.log:

[...]
# Option:  logtarget
# Notes.:  Set the log target. This could be a file, SYSLOG, STDERR or STDOUT.
#          Only one log target can be specified.
# Values:  STDOUT STDERR SYSLOG file  Default:  /var/log/fail2ban.log
#
#logtarget = SYSLOG
logtarget = /var/log/fail2ban.log
[...]

Then create the system startup links for fail2ban and start it:

chkconfig --levels 235 fail2ban on
/etc/init.d/fail2ban start

 

21 Install rkhunter

rkhunter can be installed as follows:

yum -y install rkhunter

 

22 Install Mailman

Since version 3.0.4, ISPConfig also allows you to manage (create/modify/delete) Mailman mailing lists. If you want to make use of this feature, install Mailman as follows:

yum -y install mailman

Before we can start Mailman, a first mailing list called mailman must be created:

touch /etc/mailman/aliases
touch /var/lib/mailman/data/aliases
/usr/lib/mailman/bin/newlist mailman

[root@server1 tmp]# /usr/lib/mailman/bin/newlist mailman
Enter the email of the person running the list: <-- admin email address, e.g. [email protected]
Initial mailman password: <-- admin password for the mailman list
To finish creating your mailing list, you must edit your /etc/aliases (or
equivalent) file by adding the following lines, and possibly running the
`newaliases' program:

## mailman mailing list
mailman:              "|/usr/lib/mailman/mail/mailman post mailman"
mailman-admin:        "|/usr/lib/mailman/mail/mailman admin mailman"
mailman-bounces:      "|/usr/lib/mailman/mail/mailman bounces mailman"
mailman-confirm:      "|/usr/lib/mailman/mail/mailman confirm mailman"
mailman-join:         "|/usr/lib/mailman/mail/mailman join mailman"
mailman-leave:        "|/usr/lib/mailman/mail/mailman leave mailman"
mailman-owner:        "|/usr/lib/mailman/mail/mailman owner mailman"
mailman-request:      "|/usr/lib/mailman/mail/mailman request mailman"
mailman-subscribe:    "|/usr/lib/mailman/mail/mailman subscribe mailman"
mailman-unsubscribe:  "|/usr/lib/mailman/mail/mailman unsubscribe mailman"

Hit enter to notify mailman owner... <-- ENTER

[root@server1 tmp]#

Open /etc/aliases afterwards...

vi /etc/aliases

... and add the following lines:

[...]
mailman:              "|/usr/lib/mailman/mail/mailman post mailman"
mailman-admin:        "|/usr/lib/mailman/mail/mailman admin mailman"
mailman-bounces:      "|/usr/lib/mailman/mail/mailman bounces mailman"
mailman-confirm:      "|/usr/lib/mailman/mail/mailman confirm mailman"
mailman-join:         "|/usr/lib/mailman/mail/mailman join mailman"
mailman-leave:        "|/usr/lib/mailman/mail/mailman leave mailman"
mailman-owner:        "|/usr/lib/mailman/mail/mailman owner mailman"
mailman-request:      "|/usr/lib/mailman/mail/mailman request mailman"
mailman-subscribe:    "|/usr/lib/mailman/mail/mailman subscribe mailman"
mailman-unsubscribe:  "|/usr/lib/mailman/mail/mailman unsubscribe mailman"

Run

newaliases

afterwards and restart Postfix:

/etc/init.d/postfix restart

Now open the Mailman Apache configuration file /etc/httpd/conf.d/mailman.conf...

vi /etc/httpd/conf.d/mailman.conf

... and add the line ScriptAlias /cgi-bin/mailman/ /usr/lib/mailman/cgi-bin/. Comment out Alias /pipermail/ /var/lib/mailman/archives/public/ and add the line Alias /pipermail /var/lib/mailman/archives/public/:

#
#  httpd configuration settings for use with mailman.
#

ScriptAlias /mailman/ /usr/lib/mailman/cgi-bin/
ScriptAlias /cgi-bin/mailman/ /usr/lib/mailman/cgi-bin/
<Directory /usr/lib/mailman/cgi-bin/>
    AllowOverride None
    Options ExecCGI
    Order allow,deny
    Allow from all
</Directory>


#Alias /pipermail/ /var/lib/mailman/archives/public/
Alias /pipermail /var/lib/mailman/archives/public/
<Directory /var/lib/mailman/archives/public>
    Options Indexes MultiViews FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
    AddDefaultCharset Off
</Directory>

# Uncomment the following line, to redirect queries to /mailman to the
# listinfo page (recommended).

# RedirectMatch ^/mailman[/]*$ /mailman/listinfo

Restart Apache:

/etc/init.d/httpd restart

Create the system startup links for Mailman and start it:

chkconfig --levels 235 mailman on
/etc/init.d/mailman start

After you have installed ISPConfig 3, you can access Mailman as follows:

You can use the alias /cgi-bin/mailman for all Apache vhosts (please note that suExec and CGI must be disabled for all vhosts from which you want to access Mailman!), which means you can access the Mailman admin interface for a list at http://<vhost>/cgi-bin/mailman/admin/<listname>, and the web page for users of a mailing list can be found at http://<vhost>/cgi-bin/mailman/listinfo/<listname>.

Under http://<vhost>/pipermail/<listname> you can find the mailing list archives.
