DHCP BasicsDHCP Basics

Overview

•What is DHCP?•Why use it?•How does it work?

What is DHCP?

DHCP allows a host to learn its configuration parameters from a server. It automates IP configuration, making it much easier to connect to a network. It allows re-use of IP addresses.

Why use DHCP?•Visitor convenience•Speeds setup of new machines•Simplifies conference room connections•Allows roaming laptops•Centralizes IP management

DHCP BasicsDHCP BasicsHow does DHCP work?1. Server discovery

• Client DHCPDISCOVER packet asking “Who can give me DHCP information?” Hello

2. Servers make an offer• All servers on the subnet unicast a DHCPOFFER packet saying “I can supply you with DHCP information, if you like.” What Do You need

3. Client requests•The client selects one of the responses, and broadcasts a DHCPREQUEST packet saying “I choose server XYZ. Server XYZ, here’s my MAC address, what’s my IP address?” Give Me An Address•The unchosen servers treat this as a rejection.•The request can specify a preferred IP address, if the client has a preference.•The request can ask for additional information.

4. Server responds Here It is and for How long•The server responds with a DHCPACK packet saying “Here is your IP address. It’s good for 24 hours.”•The response can contain additional information, if the client asked for it.•The server records that the IP address is in use.

5. Client releases You Can Have it Back•The client finishes it’s work, and send a DHCPRELEASE packet saying “I’m done with the IP address.”•The server records that the IP address is not in use.


Clients refresh leases• When half the lease time has expired, a client broadcasts another DHCPREQUEST packet saying “I choose server XYZ. Server XYZ, I want IP address N. Can I have it?”. The server responds yes or no.

Servers can refuse• If a server can’t supply an unused IP address, or if the server can’t supply an IP address that matches the client’s MAC address, the server sends a DHCPNAK packet saying “you can’t have an IP address”. The client is then free to make another request.

Clients preserve addresses• A client can remember its last-used IP address in non-volatile memory. When it boots, it can request the address from the server. This improves the chances that a client will retain the same IP address over long periods of time.


What DHCP can provide•IP address and lease time•subnet mask•default route•DNS, NIS, LPR, NTP, logging server(s)•WINS NBNS node type•More

Static vs. dynamic addresses•DHCP servers manage two kinds of IP addresses: o Static IP addresses, which the server gives to clients based on the client’s MAC address o Dynamic IP addresses, which the server gives to clients as requested. These come from a “pool” of addresses in a subnet, set aside for this purpose

1. The switch can be programmed with many Network names. All access points transmits these network names.

2. Network Name (SSID) Closed Broadcast ( Cant See the Network Name under the “Available Wireless Networks” Window.

3. Authentication:

• WEP authentication encrypts data going across the airwaves so intruders can not snoop and reconstruct the packets intelligibly.

• WEP is either set to be shared or can run open mode.

• Open (Airespace): If user gets SSID right but WEP wrong a connection will be displayed but access will not be provided.

• Shared (Apple Basestation): User must have both correct to show a connection.

• 128 Bit Vs 40 bit.

• 128 Bit 13 Characters (ASCII) 26 Characters Hex

• 40 Bit 5 Characters (ASCII) 10 Characters Hex

• 802.1x: Uses a Key loaded in each client device and in a special server (RADIUS) located at the site. Wireless Switch checks the network name and sends client information to RADIUS server to compare the key for authentication then checks the client’s username and password for authenticity.

• Web Authentication: Passwords are added to the switch. Users must load the appropriate network name, then open a browser to authenticate the password list on the switch.

Summary: IP printing is the ability for a printer to use TCP/IP protocols (such as LPD/LPR, IPP, or Socket or Jet Direct) to make itself accessible to your computer. If the printer you want to use is not listed when you print, you can add it to your list of available printers. To add an printer using IP, you need to know its IP address or DNS name. See your network administrator for assistance.

Summary: Unlike WindowsXP, Windows2000 wireless client utilities are different from vendor to vendor and even within versions of a vendor’s client utility. To that end this instruction document will cover the ETS recommended Client Card (Dell True Mobile and Proxim ABG Client Card) and discuss differences in the District’s most popular client software.

•In most cases the Client card will come embedded on the laptop and pre configured for a Default setting. •Configuration is all that will need changing. In cases where there is no client card pre installed, ETS recommends the Proxim ABG combo Card. •In this case both the drivers and Client software will need to be installed. •***** Important**** Never insert the card in the laptop until the software is loaded. •If you do insert the card first and continue through the load procedures, you will need to uninstall the device driver from “Windows 2000’s Device Driver window located in the Control Panel by double clicking on the “System” Icon.

Both the True Mobile and Proxim ABG Client Card configuration tool are similar in appearance and can be accessed by double clicking on the wireless icon in the systems tray or through [Start-Programs-Dell True Mobile or Orinoco Wireless Client]

Step 13: Click the OK button.



Step 14: Click on the Advanced TabStep 15: Make sure that Open is highlighted in the 802.11 Authentication ModeStep 16: Click on OK



Step 17: The Profile Management Details will show the network name in SSID 1 and the Profile icon will indicate that it is connected to the network.

Note. Open WEP Key architecture will depict that the client device is connected to the network even though the WEP password is incorrect. If the client can not access the network for any reason, double check the password was entered correctly.
