Sometime if we didn't properly shutdown a server that running linux, it will cause a crash for the filesystem.
We need a tool that able to repair it immediately, the tool is FSCK or file system consistency check.
Below is the fsck command :
Usage: fsck [-sACVRTNP] [-t fs-optlist] [filesystem] [fs-specific-options]
Example :
I have a drive /home or /dev/sda3
Then the next step is we need a root access to run the command.

Sometimes when you install some packages, it will automatically find others dependency
one of them may be curses.h: No such file or directory
in this case i'm using CentOS as a server.
So we will need to install ncurses-devel and ncurses using yum.
Below is the step to install it.
1. Login as root into your CentOS server
2. Type a command line below
# yum install ncurses-devel ncurses
If everything success then you are good to go.

I just figure it out a simple way to banned country ip address using CSF.
If you are using a CSF you can edit your CSF config files like below :
Edit csf.conf
#vi /etc/csf.conf
Edit two letters country code in CC_DENY files.
Example : i want to banned US, ID, HK country
CC_Deny = US,ID,HK
If you want to banned others country.
You can take a look link below for the Country Code

There is another way to using ssl with apache 2.x
The common solution is using OpenSSL with Apache 2.x
But right now i trying to get Apache 2.x to work with mod_gnutls
FYI, GnuTLS support TLS 1.2 and TLS 1.1 that also supported by OpenSSL
But GnuTLS will not supported SSL 2.0
We need to prepare anything related to GnuTLS to work with Apache 2.x
First we need to install those packages below :
Login as Root
1. GnuMP
#mkdir /root/temp
#cd /root/temp

What is AWStats ?
AWStats is a web statistics and log analyzer which create a statistics reports based on rich data from apache or server logs.
First We need to install AWStats in FreeBSD server
- Login into the FreeBSD server using SSH and root access
# cd /usr/ports/www/awstats
# make
# make install
# make clean
After AWStats is installed on the server we will need to configure our apache webserver.
Usually if we are installed Apache from ports then the apache config files will be stored in
/usr/local/etc/apache22/httpd.conf
