RE: [tlug] "Linux Friendly" ADSL Providors

["James Cluff" <jc@example.com>]

A switch is similar to a hub, you need neither if you get a router with
multiple eithernet ports sufficient for you lan.

When ADSL is installed, they will put the modem on the line for you most
likely.  You run a patch cable from the modem to the router.  You run
another patch cable(s) from the router to your boxes.

You probably then configure your router from one of your computers per the
instructions in the router box via your web browser.

DHCP and NAT are provided by many  proabably most routers.  DHCP provides
the IP addresses to your internal Lan, and NAT(network address translation)
translates the TCP/IP protocols from the internet - public ip to the lan
private ip.  So your lan has private IP addresses, but traffic from the
public or routable address from the modem is being forwarded to the lans
private addresses so you can access it from your local boxes

Cheers

Thanks to all for the replies.  Just a few more questions.  I understand
that
to get the setup I'd like I need an ADSL connection and modem, a router, and
a hub.  Is there anything else that I need.  I understand that some routers
have built in hubs, allowing you to setup a LAN with just the one unit, plus
of course the modem.  I want to have a connection with a little plugs as
possible.  Do I need a switcher? I've seen them at the shops and in
catalogues but what exacly does a switcher do?  Are they to use one monitor
with two computers or do they have other uses.  What  is an NTTP Server?
You
also mentioned NAT and DHCP.  I've heard of DHCP but don't understand what
it
means.  I'm using Redhats ppp internet dialler with my present ISDN
connection, which for some reason works at a snails pace on linux.  I gather
that If I donwload Roaring Penguin that'll handle the pppoE side of it.
Once
again thanks for the help.  Cheers!
