ntop is a network traffic tools that shows network usage in a real time. One of the good things about this tool is that you can use a web browser to manage and navigate through ntop traffic information to better understand network status.

Also Ntop monitors and reports hosts traffic and supports these protocols:

14 Webalizer

To install webalizer, just run

yum install webalizer

15 Synchronize The System Clock

If you want to have the system clock synchronized with an NTP server do the following:

yum install ntp
chkconfig --levels 235 ntpd on
ntpdate 0.pool.ntp.org
/etc/init.d/ntpd start

12 Apache2 With PHP

Now we install Apache with PHP (this is PHP 5.1.6):

yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel

Then edit /etc/httpd/conf/httpd.conf:

vi /etc/httpd/conf/httpd.conf

and change DirectoryIndex to

11 Postfix With SMTP-AUTH And TLS

Now we install Postfix and Dovecot (Dovecot will be our POP3/IMAP server):

yum install cyrus-sasl cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain postfix dovecot

Next we configure SMTP-AUTH and TLS:

8 Quota

(If you have chosen a different partitioning scheme than I did, you must adjust this chapter so that quota applies to the partitions where you need it.)

To install quota, we run this command:

yum install quota

Edit /etc/fstab and add ,usrquota,grpquota to the / partition (/dev/VolGroup00/LogVol00):

vi /etc/fstab

4 Adjust /etc/hosts

Next we edit /etc/hosts. Make it look like this:

vi /etc/hosts

Now we select the software we want to install. Select nothing but Servers (uncheck everything else). Also don't check Packages from CentOS Extras. Then check Customize now, and click on Next:

This tutorial shows how to set up a CentOS 5.0 based server that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of CentOS 5.0, but should apply to the 64-bit version with very little modifications as well.

11 ProFTPd

ISPConfig has better support for proftpd than vsftpd, so let's remove vsftpd:

yum remove vsftpd

Because CentOS has no proftpd package, we must use a third-party yum repository to install it:

cd /etc/yum.repos.d/
wget http://centos.karan.org/kbsingh-CentOS-Extras.repo
rpm --import http://centos.karan.org/RPM-GPG-KEY-karan.org.txt

9 Postfix With SMTP-AUTH And TLS

Now we install Postfix and dovecot (dovecot will be our POP3/IMAP server):

yum install cyrus-sasl cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain postfix dovecot

Next we configure SMTP-AUTH and TLS:
