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.

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

Here come to my attention when i want to automatically have my new linux/unix users to change the password when they login into the server.
Login into your server with root access
type chage command :
#chage -d 0 <username>
example i have a username : sentono
#chage -d 0 sentono
-d mean : we will force user to change password when they login into the server for the first time

First, we need to know what is NFS ?
NFS is a network file system something like a distributed file system protocol that allowing user on a client computer to access files over network.
For Example : we have few NFS server here and we want to know
how to see all exported file system from unix server using a command line linux
We can using showmount command to see the mount information from NFS server.
Example we have a NFS server named : media10 and the ip address : 10.100.100.1

There are so many tools that able to check the hidden process and port, the tools are rootkits/lkms/unhide etc.
In this tutorial i will discuss something more simple to use and the tools is UNHIDE.
Unhide is a tool to find hidden processes and TCP/UDP ports by rootkits / LKMs or by another hidden technique. This tools works under both Linux / Unix, and MS-Windows operating systems.
It detects hidden processes using three techniques:
The proc technique consists of comparing /proc with the output of /bin/ps.
The sys technique consists of comparing information gathered from /bin/ps with information gathered from system calls.
The brute technique consists of bruteforcing the all process IDs. This technique is only available on Linux 2.6 kernels.
