Lets say I have 2 PCs, and one ethernet connection. Do I need to get a hub in order to get both connected to the 'net? What do I need?

Alternatively, how would I set up one as a server, and the other connected to it? Would I need a hub then? Or am I describing the same thing.....help a n00b out. And be gentle

When you say you have one ethernet connection, what exactly do you mean? Also, how do you connect to the 'net? Cable/DSL/Dial-Up/Carrier Pigeon?

I think regardless you need to get a hub....

College LAN I have only my IP though.... (the one that the Uni gives me).

Would I end up making a "mini subnetwork" from the campus' network?

If you got a second network card in your computer that's connected to the college net.. you could just connect the two via a cross-connect cable..

Ryan

So I'd need 3 NICs? One for the connection to the LAN, and two to connect the two boxes?

a hub is prob the best way

yea a hub would be better if you don't already have one. My dorm had one which you could connect up to 3 PCs. Just connect your server and regular comp to the hub. Set up your server box with the IP the university gives you and then just use that as your proxy server for your main machine.

Are you using Windows or Linux on your server?

I don't have a server, and I'm only thinking about setting it up I only have one NIC right now!

Easy. If you have a few bucks, drop a Franklin or two on a Linksys 5-port router and hook up all of you computers at once. The router itself will retain your schools static ip address, as well as act as a DHCP server for your other 2 comptuers. You will have internet connectivity on each computer as well as file sharing (if you choose to enable it)

Each computer needs to have only 1 NIC.

HTH

I was in your same situation last year. I go to school at Uvic (Victoria, BC, Canada). Here is what i have setup for my self and suggest (if funds are there) to do. What you will need: 1) Your normal pc 2) A p100 (486 might even work) w/ 16mb's ram if possible and 500mb's of hd space. 3) 3 ethernet cards 4) A hub (4/5 port 10 or 10/100 whatever your budget allows)
5) 3 or 4 rj45 ethernet cables

For sake of my explaination i will refer to the p100 computer as the gateway and your normal pc as the internal computer. Start by grabing a copy of linux at www.redhat.com. 7.1 or 7.2 whatever is the current version.

Let me describe what were are going to do. We will install redhat on the gateway machine along with the two new ethernet cards that you bought at a local used computer store for about 15$ canadian each (so like 4 american). You are going to connect your first ethernet cable from the wall jack in your dorm room to one of the ethernet cards. You are going to then connect a cable from the other ethernet card into your hub (any port on the hub EXCEPT the uplink). Then you are going to plug your internal computer into another port on the hub (any port EXCEPT the uplink). Once all the cables are connected the hardware will be all configured for your new personal network. Next you will have to move to software. I would start by reading the manpages on www.redhat.com that relate to ipmasqurading or ipchaining. If you can't figure it out from that give me an email (jeffsey@hotmail.com) and i can configure it remotely for you (isn't linux great). Basically what you are going to have to do is Give your the ethernet card from your gateway machine that is plugged into the wall jack all your ethernet settings such as (i will make some stuff up for example) ip: 169.69.69.69 netmask: 255.255.255.0 dns: 169.1.1.0 (i am just making this up) gateway: 169.69.1.1
and any others that i missed. The ethernet card that is plugged into the hub should be assigned the following info
ip: 10.1.1.1 (this isn't made up...use these settings)
netmask: 255.255.255.0 dns: 169.1.1.0 (this should be the same dns server as on the other ethernet card) gateway: 169.69.1.1 (also should be the same as the other ethernet card). That should take card of ethernet settings for the gateway. Then for ever computer that you add to your network simply assign it an ip (i suggest 10.1.1.2 anything above 1 b/c that is your gateway machine. For ever additional computer added simply increment the last number of the ip ie. 10.1.1.3, 10.1.1.4, 10.1.1.5). Assign a netmask 255.255.255.0 (depending on your network) dns: 169.1.1.0 (dns will always be the same as your gateway for every internal computer) And for the gateway your will use 10.1.1.1
This makes sense b/c for your internal computer the gateway device is your p100 running linux. And for your gateway machine the gateway is whatever your edu connections gateway is. So basically what is happening once this all works is that all the packets from your internal computer will be routed out its ethernet card.....to the hub.....to the gateways ethernet card (10.1.1.1) then to the other ethernet card (your ip: 169.69.69.69) and then out that ethernet card into the wall jack and out to the internet. Well my calculus homework is calling so that is all i will say for this post. If you are having problems setting this up or have any questions about my post please feel free to email me: jeffsey@hotmail.com


Another problem with a semi free solution thanks to open source!! Linux for life :-)

Whoa, thanks XtrEmE! It'll take me a bit to digest all that (not only am I a linux n00b, I'm also a networking n00b). If I can get ahold of an old system, I'll give it a shot I'm hoping to do this for fun, not anything else, so it's not a big deal.

Why not register for the forums? Getting help like that is quite nice
