Understanding Active Directory and DHCP Configuration

Posted on May 19, 2025 in Contemporary Music Composition

Define Active Directory: Provides the ability to establish a single login and easier management of users.

What services must be in place prior to the installation of a RIS server? Having DNS, DHCP, and Active Directory.

Define Remote Desktop. It allows us to access a server remotely and perform administrative tasks from the terminal.

  • DNS Server: Domain Name System (DNS) can find the IP address of a PC’s name.
  • DNS Forwarder: Designated by other internal DNS servers for use in consultations to resolve external DNS domain names or outside the local domain.
  • Resolution: Returns the IP address for the requested resource.
  • Inverse Resolution: A computer name based on the IP address.

The protocol DHCP Server: Dynamic Host Configuration Protocol (DHCP) is a server that receives requests from clients requesting IP network settings.

  • Scope: An administrative grouping of computers or clients in a subnet using DHCP service.
  • Grant: A period of time specified by the DHCP server during which a client machine can use an assigned IP address.
  • Reserve: Consists of reserving some IP addresses to always give the same client PCs so that each one always gets the same IP address.
  • Range: A DHCP range is defined by a group of IP addresses on a particular subnet.

How does the DHCP server know the client’s MAC address to proceed with the allocation of reserved IP? By request.

What parameters can a DHCP server provide to a client? IP address, Subnet Mask, Gateway, DNS servers, etc.

Define Web Server. Discuss what services these servers can offer:

  • It is a program designed to transfer hypertext and HTML web pages.

What is a website user? A website user is anyone who accesses the site, but it is encrypted information that requires a certificate.

What are private Web folders? Anyone can access them using a username and password.


AMENDMENTS to the DHCP service configuration (Linux):

  • a. Establish an IP range from 192.168.6.10 to 192.168.6.30.
  • b. Set DNS server addresses to 80.58.0.11 and 80.58.37.11.
  • c. Set IP refresh time to 1 hour and a maximum of 12 hours.
  • d. Set the gateway to 192.168.6.1.

The configuration file for DHCP is located at: /etc/dhcp3/dhcp.conf

Subnet: 192.168.6.0 netmask 255.255.255.0 (range 192.168.6.10 192.168.6.30); -option domain_name_servers 80.58.0.11 80.58.37.11; -option routers 192.168.6.1; -default_lease_time 60; -max_lease_time 720.

Create an IP reservation for a host with a MAC address MYNAME called 00:0c:29:c9:46:cc (Linux). What changes need to be made in the dhcpd.conf file?

# host (– # hardware ethernet MAC – # filename “maria.maria.com” – # server_name “maria.maria.com” #)

Set up the server configuration file dnsmasq (Linux) if it is not configured. Indicates step by step how to operate the DNS service.

Run: sudo apt-get install dnsmasq and edit /etc/resolv.conf.

Which file would change to make a machine called TEST a DNS client (Linux) for the dnsmasq service? /etc/dhcp3/dhclient.conf

a. What is the instruction? Send host_name 2ESIPC05.PRUEBA.

IP LOOKUP IN LINUX: ifconfig

Create a web page with the following characteristics:

  • a. The IP access can be.
  • b. The access can be through the server name (example: 2esipc06).
  • c. Access may be by URL: http://www.maria.com.

Modify the /etc/hosts file to include the IP, name, and URL.

Create a web user with the following characteristics:

  • a. The user is called MyName.
  • b. Access to the site should be using the domain name.
  • c. The appearance of the page is as follows:

Create a new user and within that user, create a folder called public_html and in an index located at /home/maria/index.html in public_html.
