    Enable SSH root login on Debian Linux Server

    After fresh system installation the root login on the Debian Linux is disabled by default. When you attempt to login as root user to your Debian Jessie Linux server the access will be denied eg.:

    $ ssh root@10.1.1.12

    root@10.1.1.12‘s password:

    Permission denied, please try again.

    root@10.1.1.12‘s password:

    Permission denied, please try again.

    root@10.1.1.12‘s password:

    Permission denied (publickey,password).

    To enable SSH login for a root user on Debian Linux system you need to first configure SSH server. Open /etc/ssh/sshd_config and change the following line:

    • LOGIN AS USER
    • su
    • give root pw
    • root@websites-vm-2:~#
    • nano /etc/ssh/sshd_config

    FROM:

    PermitRootLogin without-password

    TO:

    PermitRootLogin yes

    Once you made the above change restart your SSH server:

    # /etc/init.d/ssh restart

    [ ok ] Restarting ssh (via systemctl): ssh.service.

    From now on you will be able to ssh login as a root:

    $ ssh root@10.1.1.12

    root@10.1.1.12‘s password:

    The programs included with the Debian GNU/Linux system are free software;

    the exact distribution terms for each program are described in the

    individual files in /usr/share/doc/*/copyright.

    Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent

    permitted by applicable law.

    Install sudo

    apt-get install sudo

    Change DHCP to Static IP

    If the Ubuntu Server installer has set your server to use DHCP, you will want to change it to a static IP address so that people can actually use it.

    Changing this setting without a GUI will require some text editing, but that’s classic linux, right?

    Let’s open up the /etc/network/interfaces file. I’m going to use vi, but you can choose a different editor

    sudo nano /etc/network/interfaces

    For the primary interface, which is usually eth0, you will see these lines:

    auto eth0
    iface eth0 inet dhcp

    As you can see, it’s using DHCP right now. We are going to change dhcp to static, and then there are a number of options that should be added below it. Obviously you’d customize this to your network.

    auto eth0
    iface eth0 inet static
    address 192.168.1.100
    netmask 255.255.255.0
    network 192.168.1.0
    broadcast 192.168.1.255
    gateway 192.168.1.1
    dns-nameservers 192.168.1.1

    Now we’ll need to add in the DNS settings by editing the resolv.conf file:

    sudo nano /etc/resolv.conf

    On the line ‘name server xxx.xxx.xxx.xxx’ replace the x with the IP of your name server. (You can do ifconfig /all to find out what they are)

    Now we’ll just need to restart the networking components:

    sudo /etc/init.d/networking restart

    Install LAMP

    How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Debian

    Posted Oct 4, 2012 482.2kviews Debian

    About LAMP

    LAMP stack is a group of open source software used to get web servers up and running. The acronym stands for Linux, Apache, MySQL, and PHP. Since the virtual private server is already running Debian, the linux part is taken care of. Here is how to install the rest.

    Set Up

    Before running through the steps of this tutorial, make sure that all of your repositories are up to date:

    apt-get update

    With that completed, go ahead and start installing the LAMP server.

    Step One—Install Apache

    Apache is a free open source software which runs over 50% of the world’s web servers.

    To install apache, open terminal and type in these commands:

    apt-get install apache2

    That’s it. To check if Apache is installed on your VPS, direct your browser to your server’s IP address (eg. http://12.34.56.789). The page should display the words “It works!” like this.

    How to Find your Server’s IP address

    You can run the following command to reveal your VPS’s IP address.

    ifconfig eth0 | grep inet | awk '{ print $2 }'

    Step Two—Install MySQL

    MySQL is a widely-deployed database management system used for organizing and retrieving data.

    To install MySQL, open terminal and type in these commands:

    apt-get install mysql-server mysql-client

    During the installation, MySQL will ask you to set a root password. If you miss the chance to set the password while the program is installing, it is very easy to set the password later from within the MySQL shell.

    Once you’re done with that you can finish up by installing PHP on your virtual server.

    Step Three—Install PHP

    PHP is an open source web scripting language that is widely use to build dynamic webpages.

    To install PHP, open terminal and type in this command. Note: If you are on a version earlier than Debian 7, include php5-suhosin as well.

     apt-get install php5 php-pear php5-mysql

    After you answer yes to the prompt twice, PHP will install itself.

    Finish up by restarting apache:

    service apache2 restart

    Congratulations! You now have LAMP stack on your droplet!

    Step Four—RESULTS: See PHP on your Server

    Although LAMP is installed, we can still take a look and see the components online by creating a quick php info page

    To set this up, first create a new file:

     nano /var/www/html/info.php

    Add in the following line:

    <?php
    phpinfo();
    ?>

    Then Save and Exit.

    Finish up by visiting your php info page (make sure you replace the example ip address with your correct one): http://12.34.56.789/info.php

    It should look something like this:

    Step Five – Install PhpMyAdmin

    apt-get install phpmyadmin

    Give password to root user and other users same as mysql root user

    Login to phpmyadmin

    http://VM-ip/phpmyadmin

    user : root

    pw : same as mysql and phpmyadmin root user

     

    Allow root user without password in php my admin

    Login in phpmyadmin from browser

    Click users

    There will be 4 root entries

    Edit Privileges

    Click on change password

    Set no password

    Click GO

     

    Same with other entries of root entry

    If you try to login without password in php my admin from web browser

    It will give following error

     Login without a password is forbidden by configuration (see AllowNoPassword)

     

    The Solution

    Enabling the ability to manage MySQL via phpMyAdmin (when the root login is passwordless) is as easy as changing one line in a configuration file.

    We’ll set the AllowNoPassword variable, located in phpMyAdmin’s configuration file, to TRUE. On an Ubuntu 15.04 server edit the following file:

    nano /etc/phpmyadmin/config.inc.php

    For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor

    Find the line:

    // $cfg[‘Servers’][$i][‘AllowNoPassword’] = TRUE;

    Uncomment that line; you’ll remove the //.

    There are two instances of this line in the configuration file… be SURE to uncomment both of them!

    Exit and save the file with the command :wq.

    Be Sociable, Share!

     

     

     

    1 Preliminary Note

    I’m using a Debian 8 system here with the hostname debian.example.com and the IP address 192.168.1.100.

    I will use the nano editor in this tutorial to edit config files on the shell. Nano can be installed with the command:

    apt-get install nano

    If you have a different favorite shell editor like joe or vi, then use that instead.

    To make the Linux server accessible by name from my Windows workstation, I will add a line to the hosts file on Windows. Run this command as Administrator user on Windows:

    notepad C:\Windows\System32\drivers\etc\hosts

    and add a line like this:

    192.168.1.100   debian.example.com      debian

    at the end of the file. Replace the IP address with the server IP and the hostname with the hostname that you have chosen for your server.

     

    2 Installing Samba

    Connect to your server on the shell as root user and install the Samba packages:

    apt-get install libcups2 samba samba-common cups

    Move the current smb.conf file to smb.conf.bak:

    mv /etc/samba/smb.conf /etc/samba/smb.conf.bak

    And then create a new file smb.conf file:

    nano /etc/samba/smb.conf

    With the following content:

    [global]
    
workgroup = WORKGROUP
    
server string = Samba Server %v
    
netbios name = debian
    
security = user
    
map to guest = bad user
    
dns proxy = no

    Replace WORKGROUP with the workgroup name that is used on your Windows clients. If you don’t know the name of the workgroup, run this command on the Windows client to get the workgroup name:

    net config workstation

    Then close the Samba configuration file on the server and restart Samba:

    systemctl restart smbd.service

    3 Adding Samba Shares

    Now I will add a share that is accessible by all users.

    Create the directory for sharing the files and change the group to the users group:

    mkdir -p /home/shares/allusers
    chown -R root:users /home/shares/allusers/
    chmod -R ug+rwx,o+rx-w /home/shares/allusers/

    mkdir -p /home/shares/anonymous
    chown -R root:users /home/shares/anonymous/
    chmod -R ug+rwx,o+rx-w /home/shares/anonymous/

    At the end of the file /etc/samba/smb.conf add the following lines:

    nano /etc/samba/smb.conf

    3.1 Group share

    This is a share that is accessible and writable for all members of our “users” group. Add the following config at the end of the smb.conf file.

    [allusers]
      comment = All Users
      path = /home/shares/allusers
      valid users = @users
      force group = users
      create mask = 0660
      directory mask = 0771
      writable = yes

    3.2 Home directories

    If you want all users to be able to read and write to their home directories via Samba, add the following lines to /etc/samba/smb.conf (make sure you comment out or remove the existing [homes] section):

    [homes]
       comment = Home Directories
       browseable = no
       valid users = %S
       writable = yes
       create mask = 0700
       directory mask = 0700

    3.3 Anonymous share

    You like to have a share were all users in your network can write to? Be careful, this share is open to anyone in the network, so use this only in local networks. Add an anonymous share like this:

    [anonymous]
       path = /home/shares/anonymous
       force group = users
    
   create mask = 0660
    
   directory mask = 0771
    
   browsable =yes
       writable = yes
       guest ok = yes

    Now we restart Samba:

    systemctl restart smbd.service

    4 Adding and Managing Users

    In this example, I will add a user named tom. You can add as many users as you need, in the same way, just replace the username tom with the desired username in the commands.

    useradd tom -m -G users

    Set a password for tom in the Linux system user database. If the user tom should not be able to log into the Linux system, skip this step.

    passwd tom

    -> Enter the password for the new user.

    Now add the user to the Samba user database:

    smbpasswd -a tom

    -> Enter the password for the new user.

    Now you should be able to log in from your Windows workstation with the file explorer (address is \\192.168.1.100 or \\192.168.1.100\tom fortom‘s home directory) using the username tom and the chosen password and store files on the Linux server either in tom‘s home directory or in the public shared directory.

    5 Accessing Samba from Windows

    Now you can access the samba shares from your Windows Desktop. Open the command prompt and enter “//debian” to open a file explorer:

    That shows the shares of our samba server.

    List directory with size in gb

    ls -lh

    Disk size and used

    df -h

    Remove all files and folders

    rm -r *
