FTP is used to transfer files from one host to another over TCP network. There are 3 popular FTP server packages available PureFTPD, VsFTPD and ProFTPD. 

If you are login as a normal user, you have to use "sudo" before the command, only for the first time. If your in root login, you can simply use the command, without "sudo".

     root@digidom:~# apt-get update

Step 2 � Install VsFTPD package using the below command.

     root@digidom:~# apt-get install vsftpd

Step 3 � Check the vsftpd directories and file paths.

     root@digidom:~# whereis vsftpd

     vsftpd: /usr/sbin/vsftpd /etc/vsftpd.conf /usr/share/man/man8/vsftpd.8.gz

Step 4 � Backup the /etc/vsftpd.con file

     root@digidom:~# cp /etc/vsftpd.conf /etc/vsftpd.conf.back

Step 5 � After installation open /etc/vsftpd.conf file and make changes as follows.

     root@digidom:~# vi /etc/vsftpd.conf

Step 7 � Create a User account with nologin shell and specify Home Directory location, I point to "/var/www/html/" and set the password. You can specify your own path.

Note : Do not delete this account using "userdel -rf mailftp". It will remove html directory, because this user (mailftp) home directory is /var/www/html/. 

  root@digidom:~# useradd -m -d /var/www/html/ -s /usr/sbin/nologin mailftp

  root@digidom:~# passwd mailftp

Options 1 � If you have any doubt in nologin shell, check the login shell.

     root@digidom:~# cat /etc/shells
          # /etc/shells: valid login shells
          /bin/sh
          /bin/dash
          /bin/bash
          /bin/rbash
          /usr/bin/tmux
          /usr/bin/screen
          /usr/sbin/nologin

If not there /usr/sbin/nologin just add for using this command.
     root@digidom:~# echo "/usr/sbin/nologin" >> /etc/shells

Step 8 � Check the user accounts details
     root@digidom:~# tail /etc/passwd | grep mailftp
          mailftp:x:1001:1001::/var/www/html/:/usr/sbin/nologin

Step 9 � Set the permission.

     root@digidom:~# chown mailftp:root /var/www/html/

     root@digidom:~# ll -d /var/www/html/

          drwxr-xr-x  5 mailftp root 4096 Dec 16 22:55 html/

                                  OR

     root@digidom:~# chown root:mailftp /var/www/html/
     root@digidom:~# chmod -R 775 /var/www/html/

     root@digidom:~# ll -d /var/www/html/

          drwxrwxr-x  5 root mailftp 4096 Dec 16 22:55 html/

     
     root@digidom:~# service vsftpd restart

Step 10 � If another option is create a directory inside of html user home directory point this.

    root@digidom:~# useradd -m -d /var/www/html/ftp -s /usr/sbin/nologin mailftp

    root@digidom:~# passwd mailftp

    root@digidom:~# chown mailftp:mailftp /var/www/html/ftp

How to install XAMPP on windows 7 | Free VPS

XAMPP stands for Cross-Platform (X), Apache (A), MySQL (M), PHP (P) and Perl (P). It is a simple, lightweight Apache distribution that makes it extremely easy for developers to create a local web server for testing purposes. Everything you need to set up a web server � server application (Apache), database (MySQL), and scripting language (PHP) � is included in a simple extractable file. XAMPP is also cross-platform, which means it works equally well on Linux, Mac and Windows. 

Step 1 - Download XAMPP setup from website:

Step 2 - Disable your anti-virus as it can cause some XAMPP components to behave erratically.

Step 3 - Start the installation process by double-clicking on the XAMPP installer.

Step 4 - For Windows 7 users, you will see a window pop up, warning you about User Account Control (UAC) being active on your system. Click OK to continue the installation.

Step 5 - Next you will see the Welcome to the XAMPP setup wizard screen. Click Next to continue the installation.

Step 6 - Choose the folder you want to install XAMPP. This folder will hold all your web application files, so make sure to select a drive that has plenty of space.

Step 7 - The next screen is a promo for BitNami, an app store for server software. Deselect the �Learn more about BitNami for XAMPP� checkbox, unless you actually enjoy receiving promo mails.

Step 8 - Setup is now ready to install XAMPP. Click Next and wait for the installer to unpack and install selected components. This may take a few minutes.

Step 9 - Installation is now complete! Select the �Do you want to start the Control Panel now?� checkbox to open the XAMPP control panel.

Step 10 - The XAMPP control panel gives you complete control over all installed XAMPP components and tart the apache and mysql.

Step 11 - Test the XAMPP, open your web browser and type in: http://localhost or 127.0.0.1. Select your language from the splash screen.

You should see the following screen. This means you�ve successfully installed XAMPP on your computer.

Step 12 - We will now test whether XAMPP has installed PHP successfully. Open Notepad and type the following into a new document:

     <?php
       phpinfo();
     ?>

Save this file as �test.php� in c:\xampp\htdocs\ (or whichever directory you installed XAMPP in).
Navigate to http://localhost/phpinfo.php. You should see the �Hello World� message

Step 13 - You can access phpMyAdmin by entering http://localhost/phpmyadmin in your web browser.

That's it.....
