EPEL (Extra Packages for Enterprise Linux) is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs, such as CentOS and Scientific Linux.
Adding EPEL repo is very easy:
rpm -Uvh epel-release-6-8.noarch.rpm
From unknown reason for me, CentOS 6.x goes without php-mcrypt package and it is impossible to install this rpm from base repos. Some apps will complain about this and one of the solutions is to install this rpm from EPEL repo… After you added EPEL repo, type:

Turn on vsftpd auto start with
chkconfig --level 235 vsftpd on
and edit the next:

2. Uncomment chroot_local_user=YES line (In CentOS 5.x you will need to add this line)
3. Change the default port number from 21 to XXXXX (where XXXXX is above 1024) with listen_port=XXXXX
It this line doesn’t exist, paste it to the end of the file. Be sure that port XXXXX is accessible.
Restart vsftpd with service vsftpd restart. Please keep in mind that changing default port number doesn’t mean that your server is 100% secured. It will help you to avoid random dictionary attacks and your log files will be much smaller. Good password is a MUST.
Webmin is a web-based app for system administration for Unix/Linux. With Webmin, you can setup user accounts, web server, mail server and much more.

It is good idea to change the default port. To do this, open miniserv.conf (usually /etc/webmin/miniserv.conf) with
and change the default port number from 10000 to something more secure (port=23345 for example). Save the file and restart Webmin (service webmin restart).
