If i have 2 ethernet cards on one computer, and 1 ethernet coord on the other, is there a way to make it so I can connect one computer to another, then have the other ethernet coord connected to the net?

Illistration---
Internet (Hub/Switch/Router/Modem)---Computer 1----Computer 2

Instead of..

Internet (Hub/Switch/Router/Modem)---Computer 1
Internet (Hub/Switch/Router/Modem)----Computer 2

Will this work? What will it do if not? Will it not let it have net access...but will still enable the 2 computers to talk?

to directly connect the 1 with two cards to the 1 with only 1 you will need a certain cat 5 cable... i think its called a patch cable or a crossover cable.... a normal cat 5 cable will not work.

those should work for what you need

You will need two NICs in computer 1, if I read your setup correctly.

Both configurations will work.

Code: Show/Hide

CONFIG1: internet --> PC1 --> PC2

CONFIG2: internet --> PC1
internet --> PC2

I recommend CONFIG1, but it depends on your needs.

Using CONFIG2 you'll need firewall/antivirus installed on both PC1 and PC2. Using CONFIG1, the IP of the PC1 card connected to the router becomes the gateway of your LAN. Using CONFIG2, the internal IP of the router becomes the gateway.

BTW, what are you using? modem, router or what?

I said it wrong... the gateway for CONFIG1 is the IP of the internal PC1 card (the one connected to PC2).

Describe your configuration (are you using router? are you using switches?) and we'll give you more detailed information on how to set it up.

The best way to do it is to buy yourself one of those routers they sell in stores, and have your setup like this

Cable/DSL modem
|
|
Router --------- Computer 1
|
|
Computer 2

Because that way your computer 2 is not dependent on computer 1, which is always a bad idea.

If i have Internet--->Computer 1----> Computer 2, will I need to install any kind of software/etc? Also, will Computer 1 ALWAYS need to be on?

I just think you need to have the proper TCP/IP protocol for both Computers.

If you have the internet going into Computer 1, you'll need a Straight-through cable, then a crossover cable going from computer 1, to computer 2.

But, you'll need to make sure that you get the two computer talking first, before computer gets any internet.

And yes, computer 1 will always need to be on.

NAT must be running on computer 1. You can try WinRoute (firewall+gateway)

Just use internet connection sharing on computer 1.

Yes, it will always need to be on.

The problem is that you'll have to get a second network card for computer 1. If you're going to do that, you might as well go for the better option of getting a router. The router will allow you to connect more than just one extra computer, should the need arise (and it will).

If i just use a regular Ethernet coord, will it work?

Dr Brain - Wed Aug 17, 2005 9:52 pm

No.

I network computers as part of my job. Get a router. It can't cost much more than an extra network card.

I have a router, im trying to avoid having coords all over the place...

And what i meant was...

coord
2 nic cards---> 1 nic card
Internet---->Computer---->Computer 2..

I don't understand your diagram. Try again?

And it's cord, not coord. Coord is short for co-ordinate.

Ok, but it would be like this: because he doesn't have a router currently (or so I have gathered)

Code: Show/Hide

(INTERNET)--------(NIC1:Computer1:NIC2)--------(NIC1:Computer2)

COMPUTER1:
NIC1: IP: 86.48.123.82
NIC2: IP: 192.168.0.1

COMPUTER2:
NIC1: IP: 192.168.0.2
Gateway: 192.168.0.1

Under this setup you would need a straight through cable between your cable modem and computer 1. You would need a crossover cable between computer 1 and computer 2, though you could do the trick with a hub somewhere between the computers.

You will have you crimp your own wire if you want to make a crossover wire. I don't believe they sell them in stores any more.

I have a router, and all i wanted to know is if it was possible, and if so, how...then..could I just use a regular ethernet cord. If not, theres no use in me buying a special cord, I might as well just get a 100ft cord and run the line.

Best Buy (and most similar electronic stores in the US) will gleefully rape you to the tune of 15$ for a 10' crossover cable.

Though, Id only recommend that if you dont have the (insert excuse here) to make your own.

how do you make your own crossover coord?

Edit: Since you where going to say http://google.com...i took the liberty to do it myself

http://www.littlewhitedog.com/content-8.html

This calls for a crimper, which would only cost more $$. Would be best for me to just go buy a wireless card for the price of getting a crimper, not to mention the pain and suffering of making it

A lot of us crimp our own wires because we've had to network our houses. You can't run wires with ends already attached through walls and floors.

Crimping them isn't a tough thing to learn. You go through a couple extra ends when you're first starting, but eventually you get to a point where you're making good wires every time.

Crimping wires is a lot of fun, I think. But yeah, like Brain said, it takes you a few tries to get an end to work.

You network'd your own house? There are people to do that stuff for you.

You could buy some little automated machine for it too, I think I'll get one of those.

I learned to do it manually a while ago, getting better at it (it works after 1 or 2 times of trying).

I actually do buy network cables, their quality is just better.
Crimping cables is just for when I need to fix one (when a connector got fucked up) or whatever.

Indeed, I found a nice sized bundle of network cables outside the university's... computer place, then bought a crimper and saved probably 5 bucks. :\

I would be one of those people. I got paid to do it today, even.
