...DHCP Server configuration 1) Configure the network interface to give a static IP address to the DHCP server Edit the file /etc/network/interfaces [pic] 2) Use the command sudo apt-get install isc-dhcp-server in the terminal to install DHCP. 3) For the DHCP to assign Ipv4 addresses edit the file /etc/dhcp/dhcpd.conf and provide the range of address you want to the DHCP server to assign. [pic] 4) For ipv6 address, create a new file dhcpd6.conf and then configure the range of ipv6 addresses which needs to be assigned. The file should be created in /etc/dhcp/dhcpd6.conf [pic] 5) For ipv6, edit the file /etc/sysctl.conf and provide the below configurations. net.ipv6.conf.all.forwarding=1 net.ipv6.conf.all.autoconf=1 net.ipv6.conf.all.accept_ra=1 [pic] 6) Enter the below commands to enable the configurations made above. sudo sysctl -w net.ipv6.conf.all.autoconf=1 sudo sysctl -w net.ipv6.conf.all.accept_ra=1 sudo sysctl -w net.ipv6.conf.all.forwarding=1 7) Install the router advertisement daemon or radvd by using the command Sudo apt-get install radvd 8) Create file /etc/radvd.conf and put the internal interface and prefix there.

...starting the next task. To command the computer to wait until the program finishes, the start command used with the /wait switch or /w for short is used. For example to install a DNS Server role the command line input would be start /w ocsetup DNS-Server-Core-Role. 2. To remove a Server role the switch /uninstall is used. The switch is typed at the end of a command line input of the start, /w, ocsetup and then name of the role which is to be removed. For an example, if say the Server role of DHCP was needed to be uninstalled the command line input would be start /w ocsetup DHCPServerCore /uninstall. 3. To start and configure the DHCP Server role once it has been installed two commands will be needed. To configure the service the command to input would be sc config dhcpserver start= auto. This command will bring up the ChangeServiceConfig function for the DHCP Server role. To start the DHCP Server role the command line input would be net start dhcpserver. 4. To configure a DNS zone once a DNS Server role has been installed the command line input to use is dnscmd. The dnscmd command is used in conjunction with the / command followed by the DNS configuration that is to be changed. For example if the DNS server cache need to be cleared the command line input would be dnscmd...

...*part one talk about DNS servers. What are they what do they do basic configuration and variation of configuration. As the network administrator for Contoso, Ltd to resolve the issue of users on the company network reporting that they can use host names to connect to computers on the local private network, but they cannot use host names to connect to Internet destinations you have a few options. The action that will take the least amount of administrate effort to enable network users can connect to the Internet host names would be to configure NS2 and NS3 to use NS1 as a forwarder. A DNS forwarder is a DNS server that performs DNS queries on behalf of another DNS server (Shinder.T 2005). With this setup one would configure the firewall used by NS1 to allow only one DNS server to communicate with the internet. After you configure NS2 and NS3 to forwarder all queries that cannot be resolved internally will be forwarded to NS1. Because of the large amount of traffic going through NS1 the server will build a large cache of DNS data, overtime this data will allow the DNS server to process request faster(Book). Another option to solve the issue of users on the company network reporting that they can use host names to connect to computers on the local private network, but they cannot use host names to connect to Internet destinations is to configure all DNS servers to send queries outside of a network using their root hints. This is not the most desirable configuration because...

...and growth possibilities of an organization. One area that will impact the entire organization for years relates to using/installing Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP). DNS and DHCP services can be set up in an office by installing the correct equipment or through the ISP that the organization is using. Knowing what is best for the organization should be based on their current size and equipment needs. A small office with only 2 computers would not require new equipment to be installed. In this size office I would recommend statically assigning the IP addresses to the two computers and using the DNS that is on the ISP network. For an office a little bigger, with 5 computers, I would recommend that they install a router/hub in-one device which can also act as a DHCP server. These all-in-one devices are typically less than $200, will add firewall protection and have ports to connect the computers via an Ethernet connection which will allow better internet access. I would still recommend that this office use the DNS on their ISP’s network. For a larger organization with over 25 computers, I would recommend that they install a Server which will have both DNS & DHCP options. With the size of this organization, having the DNS & DHCP on site will allow for quicker response times when using the internet and the ability to not have to manage which IP addresses are assigned to which...

...There is a limit on the cable length; there is also a limit on the number of nodes that can be connected all at once. Ring This is referred to as a ring network. This is a when computers are connected to each other in a circle shape. The packet is sent around the ring until it gets where it is meant to be. You don’t need the network server to control the connection between the workstations. Each of the computers have got access to all of the same things. If one of the computers go down it will affect the whole network. The network depends on the wire which connects the computers components. Tree This network is referred to as a star bus topology; it is common to networks such as the star and bus topology. The tree topology connects groups of star networks to other star networks so you can extend them. You can expand the network easily. If one of the parts are damaged the others will not be affected. The tree topology depends on the main bus cable to keep the network running but if it breaks the whole network will go down. The more computers added then the more difficult...

...Assignment 1. DHCP Troubleshooting Dear Junior Administrator, I would start by rechecking your initial configurations to make sure the setting were saved. Once that is done, check to see if the workstations have picked up a new lease or not. If that doesn’t resolve the issue, did you check to make sure the server is up and operational? Have any Error messages or pop up’s appear with any type of warning, if so what did it say? Once the server has been checked, if it is working properly we will check these three common problems; 1. “The client might be configured to use an IP address not provided by the server. 2. The server sends a negative response back to the client, and the client displays an error message or popup indicating that a DHCP server could not be found. 3. The server leases the client an address but the client appears to have other network configuration–based problems, such as the inability to register or resolve DNS or NetBIOS names, or to perceive computers beyond its same subnet.”(Troubleshooting DHCP) On the chance that the DHCP server is off I would like you to follow these steps to try to restart the DHCP server. 1. “Start Windows Server, and log on under an account with Administrator rights. 2. At the command prompt, type net start dhcpserver , and then press ENTER. As a helpful tool Use Event Viewer in Administrative Tools to find the possible source of problems with DHCP services.”(Troubleshooting DHCP) I hope some of this...

A set of software programs that when installed and configured properly, allows a computer to perform specialized functions for numerous clients or other computers within a network. They describe the main function, or use of a computer. A certain computer can be created to perform a clear-cut function that’s greatly used in an enterprise, or perform many roles if it’s not used too much.
