ADSL -

1. Forms of ADSL Connectivity

• MAC Address Identification.
• DHCP or Static IP Addressing.
• A Combination of the two.
• ISP Specific Software.

Folow ups: There are a few ways of connecting to the ADSL modem that I am aware of.

• The first way is by MAC(Media Access Control) Address Identification. First of all a MAC Address is an address specific to each particular ethernet card that is made. The way this service works is that the ISP(Internet Service Provider) will take the MAC Address from your ethernet card and call down to the station where they will lock that MAC Address into a database. This database will then only allow this MAC Address on this particular card connect through the ADSL modem. So to allow for more than one computer to connect through this ADSL modem you will have to purchase a hub, and separate ethernet cards for each aditional computer you wish to have on the internet. You will now have to get some sort of proxy software or setup a UNIX router. This service can use DHCP or Static IP Addressing. You can setup either of these in linux with almost no trouble at all. You do need the primary and secondary DNS. your hostname, and static IP address information.
• My ISP does not use MAC Address Identification. It uses DHCP and allows 3 users to connect to the ADSL modem at one time. The only down side is that you have to run their software which makes it unusable in linux or any other OS unless you or the ISP make the program specifically. In either case it requires specific knowledge of what you are doing. And you will still have to buy the hub and the extra ethernet cards for each extra computer that you want to be able to access the internet.
• Either way for Windows or Linux you are going to have to have TCP/IP enabled to get on the internet.

Detection: IP Address's & MAC Address's

• Linux: In the console type "ifconfig" it should bring up 2 devices eth0 (your ethernet card) and lo (your local loopback) and display MAC Address and IP information.
• Windows: Click on the Start Menu and go to Run.. now type "winipcfg". You should be able to get all the information you need and more from this program.

Configuration:

• Linux: In the console type "ifconfig" it should bring up 2 devices eth0 (your ethernet card) and lo (your local loopback). If these both show up you should be able to access the internet, if not then try reinstalling the ethernet card. Now you have to got to the control panel and set the connection on the ethernet card (eth0) to connect via DHCP or specify the Static IP address information.
• Windows: Boot into windows and right click on network neighborhood. Go down to the properties section. Once there make sure that in the configuration tab that TCP/IP is there if not add it. Now reboot. Once back in Windows either run the software if your ISP gives you any or you are most likely online already.

2. Getting An Internet Connection

• I assume all the contract work has been done in order to use your ADSL modem (eg: the ADSL people have come to install the spliter and anything else you might need).
• You first need to have a working ethernet(Network Interface Card) card. And your computer must be configured for what type of ADSL connection you will be using.
• When this is done you should shut down your computer. Now turn the ADSL modem on and wait for the sync light to turn green. If it does not there is a wiring problem so call the contractors and yell at them. If it turns green like it should then you can boot your computer and when you restart you should be online. Or run the software provided by the ISP once the computer has booted into Windows.

3. Re-occouring Problems

• Be aware that most ISP's do not support Linux or any other flavor of UNIX. Just a thought when your looking for Tech. Support for your ADSL in Linux.
• I have had many problems when using more than one of the same brand name ethernet cards in one machine. I would recomend 2 different brands.

4. Networking the ADSL Service

• ISP Specified: To network the ADSL modem to other computer you will need a hub with an uplink jack and a few extra ethernet cables depending on how many computers you want networked. Now once you have this done connect the ADSL modem into the uplink jack. Now take some extra ethernet cable and plug it into jack 1 of the hub and connect it to your ethernet card on your computer. You should be able to access the internet the same way as before just run the software.
• MAC Address: Networking with this type of connection is almost the same but does have some technicalities. To share the Internet connection with this type of connectio you will need and extra ethernet card for the main(server) computer, ethernet cable, a hub with uplink, and some proxy software or a router. Now plug the ADSL modem into one of the ethernet cards and take a peice of the ethernet cable and plug it from the second ethernet card into the uplink jack on the hub. Now setup the proxy information and hook up the other client computers to the hub and they should work through the proxy conectivity.

5. Security

• Since you will be online all the time I would definatly recommend seting up a firewall or some other form of protection from the outside world.

7. Glossary of Terms Used

• ADSL (Asymetrical Digital Subscriber Line): This is they type of Internet service you will be using.
• DHCP's (Dynamic Host Configuration Protocol): Using this protocol will make your IP address change every time you get online.
• Static IP's: An IP address in this form will result in an IP address that will not change.
• ISP (Internet Service Provider): An ISP is a company that will give you your internet service.
• MAC Address (Media Access Control): A MAC address is a permanent address on every ethernet card that is manufactured and is different for each card.
• OS (Operating System): This is whatever program you use to manage your computer.
• DNS (Domain Name Service): This is how you lookup a host name and how your computer can be identified non specifically. This is used mainly for websites.
• IP (Internet Protocol) Address: This is the protocol that either assigns you an different address everytime you connect to the Internet, or it assigns only one specific IP address to your computer each time you connect to the Internet.

8. Author's Notes

• Please distribute / link this file to whomever you wish. I nor Root Access Information Security can be held responsible if anything should go wrong. What I can tell you is that this ALL worked for me and my friends that own and Alcatel 1000 EXTERNAL ADSL modem.

9. HELP!!

• I have made my own file with my own knowledge and that of others on MAC address's on how to clone them and on general information about them. If you are interested on this topic please send me and email at odarkforce@hotmail.com and tell me what you think. If you have any extra information on cloning MAC Address's the information would be greatfull. I would especially like to speak with someone who has cloned a MAC Address before and knows how to do this. I strive to learn more about this topic so any information will be helpful.
