1. To install the Apache web server on Linux, you’ll need to have administrator privileges.

2. Start by opening a terminal window and update the repositories. You can use the command “sudo apt-get update.”

3. Install the Apache web server package with the command “sudo apt-get install apache2”.

4. Once the download is complete, the Apache web server should be installed. You can start the Apache service with the command “sudo /etc/init.d/apache2 start”.

5. You can check that the web server is running by going to http://localhost in your browser. If everything is working correctly, you should see the Apache test page.

6. To configure Apache, you’ll need to edit the configuration file located at /etc/apache2/apache2.conf. Open it in your favorite text editor.

7. Once you’ve finished making changes, save the file and restart the Apache service with the command “sudo /etc/init.d/apache2 restart”.

8. Congratulations, your Apache web server is now installed and ready to go!

1. Install the DNS software:
# apt-get update
# apt-get install bind9

2. Configure the /etc/bind/named.conf.options file:
Open the file using a text editor, for example:
# nano /etc/bind/named.conf.options

3. Review the configuration and make sure that the forwarders are configured correctly:
forwarders {
8.8.8.8;
8.8.4.4;
};

4. Configure the DNS zone:
Open the file using a text editor, for example:
# nano /etc/bind/named.conf.local

Add the following entries:
zone “example.com” {
type master;
file “/etc/bind/zones/db.example.com”;
};

Create the zone file (db.example.com):
# nano /etc/bind/zones/db.example.com

Add the following entries:
$TTL 86400
@ IN SOA ns1.example.com. admin.example.com. (
2019020101 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
86400 ) ; Negative Cache TTL
;
@ IN NS ns1.example.com.
@ IN A 192.168.1.10
ns1 IN A 192.168.1.10

5. Create the reverse lookup zone:
Create the file /etc/bind/zones/db.192.168.1
# nano /etc/bind/zones/db.192.168.1

Add the following entries:
$TTL 86400
@ IN SOA ns1.example.com. admin.example.com. (
2019020102 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
86400 ) ; Negative Cache TTL
;
@ IN NS ns1.example.com.
1.0 IN PTR example.com.

6. Restart the bind service:
# systemctl restart bind9

It is not possible to find someone’s email password as passwords are encrypted and stored in a secure database. Trying to do so is a violation of the person’s privacy, and could be considered illegal. It is important to respect other people’s privacy and instead focus on protecting your own accounts and data.

1. Change the permissions of the directory:

Using the chmod command, you can give read access to the directory by running the command below:

chmod +r <directoryname>

2. Use ACLs (Access Control Lists):

To give read access to a specific user or group you can use the setfacl command.

For example, to give read access to the ‘user’ for the ‘mydir’ directory run the following command:

setfacl -m u:user:r- x mydir/

This will give the ‘user’ read access to the ‘mydir’ directory. You can also use this command to give read access to a group of users.
