Sometimes devices don’t automount, in which case you should try to manually mount it. First, you must know what device we are dealing with and what filesystem it is formatted with. Most flash drives are FAT16 or FAT32 and most external hard disks are NTFS.
sudo fdisk -l
Find your device in the list, it is probably something like /dev/sdb1.

Create the Mount Point

Now we need to create a mount point for the device, let’s say we want to call it “external”. You can call it whatever you want, just please don’t use spaces in the name or it gets a little more complicated – use an underscore to separate words (like “my_external”). Create the mount point:
sudo mkdir /media/external

Mount the Drive

We can now mount the drive. Let’s say the device is /dev/sdb1, the filesystem is FAT16 or FAT32 (like it is for most USB flash drives), and we want to mount it at /media/external (having already created the mount point):
sudo mount -t vfat /dev/sdb1 /media/external -o uid=1000,gid=1000,utf8,dmask=027,fmask=137
The options following the “-o” allow your user to have ownership of the drive, and the masks allow for extra security for file system permissions. If you don’t use those extra options you may not be able to read and write the drive with your regular username.Otherwise if the device is formatted with NTFS, run:
sudo mount -t ntfs-3g /dev/sdb1 /media/external
NOTE: You must have the ntfs-3g driver installed.

Unmounting the Drive

When you are finished with the device, don’t forget to unmount the drive before disconnecting it. Assuming /dev/sdb1 mounted at /media/external, you can either unmount using the device or the mount point:
sudo umount /dev/sdb1
or:
sudo umount /media/external
You cannot unmount from the desktop by right clicking the icon if the drive was manually mounted.

Sometimes devices don’t automount, in which case you should try to manually mount it. First, you must know what device we are dealing with and what filesystem it is formatted with. Most flash drives are FAT16 or FAT32 and most external hard disks are NTFS.

how to install Direct Admin on a clean installation of CentOS 5 and 6. The procedure is exactly the same on both these operating systems and with both 32-bit and 64-bit versions. It is very important to start off with a clean installation, as the DirectAdmin installer will take care of all software components you need.

Do you meet the system requirements?
If you have purchased your license directly from DirectAdmin.com, sign into your client account at https://www.directadmin.com/clients and click the "view" link next to your license. Verify that the server IP address and operating system is correct. Also make sure that the license is Active and Verified (if it isn't, you need to contact Direct Admin support). If you have problems with a license obtained through Woktron Web Hosting, please contact Woktron Support.

1. update CentOS to the latest version (currently 5.8 or 6.3)

yum update

2. install DirectAdmin

Begin by installing the required dependencies for Directadmin:
yum install wget gcc gcc-c++ flex bison make bind bind-libs bind-utils openssl openssl-devel perl quota libaio libcom_err-devel libcurl-dev gd zlib-devel zip unzip libcap-devel cronie
Continue by downloading the DirectAdmin setup routine using wget, set file permissions to writable with chmod and finally startup the setup routine by issuing the ./setup.sh command:
wget http://www.directadmin.com/setup.sh
chmod 755 setup.sh
./setup.sh
After the setup routine starts you will be presented with a number of options. You should have your license details ready.


(start installation routine:)
***************************************************** * * Have you run the pre-install commands? CTRL-C if not. * http://help.directadmin.com/item.php?id=354 * ***************************************************** Please enter your Client ID : xxxxx Please enter your License ID : xxxxx Please enter your hostname \(server.domain.com\) It must be a Fully Qualified Domain Name Do *not* use a domain you plan on using for the hostname: eg. don't use domain.com.

Below you will find what options you have when selecting a custom setup of DirectAdmin:
Would you like the default settings of apache 2.2 and php 5 cli? (y/n):  N
Would you like to have PHP4 or PHP5 as default? (4/5): 
Would you like to have PHP5? (yes/no): 
Would you like to have PHP5 as CLI or CGI? (cli/cgi): 
Would you like to have PHP4? (yes/no): 
Would you like to have ionCube? (yes/no): 
Would you like to have Zend Optimizer? (yes/no): 
Would you like to have an ability to update/instal MySQL using CustomBuild? (yes/no): 
Which version of MySQL you would like to have? (5.0/5.1): 
Which version of Apache you would like to have? (1.3/2.0/2.2): 
Would you like to have an ability to update/instal Exim using CustomBuild? (yes/no): 
Would you like to have an ability to install Dovecot? (yes/no): 
Would you like to have an ability to install/update phpMyAdmin using CustomBuild? (yes/no): 
Would you like to have an ability to install/update SquirrelMail webmail using CustomBuild? (yes/no): 
Would you like to have an ability to install/update RoundCube webmail using CustomBuild? (yes/no): 
Would you like to have an ability to install/update UebiMiau webmail using CustomBuild (not recommended)? (yes/no): 
Would you like to have an ability to install/update Atmail Open webmail using CustomBuild? (yes/no): 
Would you like to search for the fastest download mirror? (y/n):
When the install routine has completed, you should be ready to login to your newly installed control panel via: http://xx.xx.xx.xx:2222(where xx.xx.xx.xx is your IP address or domain name). 2222 is the port DirectAdmin normally communicates on. It is important to keep this port open in your firewall
In case you forgot your admin password enter the following:
cd /usr/local/directadmin
./directadmin i

3. update custombuild:

After having DirectAdmin succesfully installed it is now time to secure your server. A good first step would be to install the CSF Firewall. It is also important to periodically update your server. This can be done by issuing the following commands:
cd /usr/local/directadmin/custombuild
./build clean 
./build update 
./build update_versions

4. Dealing with RPM errors

When installing RPMs, errors can sometimes occur. Don't panic, solving them is usually easy. If you didn't know what to install during your RedHat installation, you might have installed a few services, such as apache and sendmail. These services must be removed before the rpm will be able to be installed.

For example, lets say you are trying to install exim and you get the following:
rpm -ivh exim-3.36-2.i386.rpm
  Preparing...                         ########################################### [100%]
  file /somefile from install of exim-3.36-2 conflicts with file from package sendmail-8.1
  ...
This would mean that sendmail is already installed on your server and you must remove it. This can easily be accomplished by running the following:
rpm -e --nodeps sendmail
Then you will be able to install your rpm. This follows for other services such as apache, apache-devel, wu-ftp, php, MySQL and so forth. If you need to figure out if you already have a service installed, you can run
rpm -q servicename
or
rpm -qa | grep substring
Where substring is just a word. For example, using "apache" might return:
rpm -qa | grep apache
apache-fp-1.3.27-2
apache-fp-devel-1.3.27-2
apache-fp-manual-1.3.27-2

This is only a quick note, on how to disable SELinux on a system using command line tools: Open file /etc/sysconfig/selinux which should more or less be like this:

# This file controls the state of SELinux on the system. 
# SELINUX= can take one of these three values: 
#           enforcing - SELinux security policy is enforced. 
#           permissive - SELinux prints warnings instead of enforcing. 
#           disabled - SELinux is fully disabled. 
SELINUX=enforcing 
# SELINUXTYPE= type of policy in use. Possible values are: 
#           targeted - Only targeted network daemons are protected. 
#           strict - Full SELinux protection. 
SELINUXTYPE=targeted


Next, find the line saying: SELINUX=enforcing and replace it with SELINUX=disabled

save and reboot.

Note: Be very careful when editing this file. the other day. occidentally changed the value of SELINUXTYPE to something other than the allowed values and managed to completely prevent my 6.4 CentOS kernel from booting. (God save the live CD's ...)

VSFTPD is a service which allows us to setup ftp server in secure way. it is Very Secure File Transfer Protocol Daemon (VSFTPD).
By default ftp server can be access anonymously ( ‘/var/ftp’ anonymous space ) and we can also configure login-based FTP sessions.

In this HowTo i will show you the login-based FTP configuration and installation.

First of Installation of VSFTPD using of course ‘yum’.


Step-1

yum install vsftpd

Setp-2 Edit main config file
vi /etc/vsftpd/vsftpd.conf
change below line as follows :
anonymous_enable=NO
local_enable=YES

Step-3 Enable ‘vsftpd’ in multi-user runlevels using ‘chkconfig’ & Start Service.
chkconfig vsftpd on
service vsftpd start

Step-3 Set SeLinux Booleon
getsebool -a | grep ftp - dupms FTP-related SELinux booleans
setsebool -P ftp_home_dir on

Now you can make login-based ftp session
Open your browser type : ftp://username@localhost or IP address of your FTP Server.

TOP 5 Best Linux OS

As part of the contest that was conducted a while back, I got around 200 responses from the geeky readers who choose their favorite Linux distributions.

Based on this data, the top spot in the best Linux distribution list goes to…

Ubuntu

My personal favorite was Ubuntu for desktop (#1 in this list) and Red Hat for servers (#5 in this list).

If you are new to any of the distros listed in the top 5, read the rest of the article to understand little bit more about those distros and find out whether your favorite Linux distribution made it in the top 5.


Linux Distro Review
Fig: Favorite Linux Distribution Voting Results

1. Ubuntu

Ubuntu 8.04 LTS Desktop
Like most of you, Ubuntu is my #1 choice for desktop Linux. I use it both at home and work. Ubuntu is the #1 in the Linux desktop market and some use Ubuntu for the servers also. Ubuntu offers the following three editions.
  • Ubuntu Desktop Edition 
  • Ubuntu Server Edition 
  • Ubuntu Notebook Remix
Additional Details:


2. Debian

Debian 4.0r8, or etch
Debian is also called as Debian GNU/Linux, as most of the basic OS tools comes from the GNU Project. Lot of other famous distributions are based on Debian, which includes our #1 distro Ubuntu and many others — such as Knoppix, Linspire, Damn Small Linux etc.,

Additional Details:


Read more about Debian Distribution at wikipedia.

3. Fedora

Fedora 10 Server Edition


Fedora is sponsored by Red Hat. If you are interested in experimenting with the the leading technologies, you should use fedora, as the release cycle is very short and fedora tends to include the latest technology software/packages in it’s distribution.

Additional Details:

Read more about Fedora Distribution at wikipedia.

4. CentOS

CentOS 5 Linux Distro
If your organization does not want to spend money on purchasing Red Hat support, but still want all the benefits of the red-hat distribution, this is obviously the best choice, as this is totally based on the red-hat enterprise Linux.

As you can imagine the Nort American Enterprise Linux vendor mentioned in the quote below is Red Hat.

From the CentOS website: CentOS 2, 3, and 4 are built from publically available open source SRPMS provided by a prominent North American Enterprise Linux vendor. CentOS is designed for people who need an enterprise class OS without the cost or support of the prominent North American Enterprise Linux vendor.

5. Red Hat


Linux Red Hat 4 Enterprise Linux for Server
This is my favorite server distribution. If an organization doesn’t mind spending dollars on purchasing the red-hat support, this is always my #1 recommendation to any organization who runs mission critical applications.
On a side note, one of the reason I like Red Hat Linux for mission critical production application is that Red Hat tends to take some of the new features from Fedora, which is well tested by the community.
