Dual Lan

On my desktop I have dual Ethernet connections. I was wondering if there was a way to hook my internet up to one, and then another computer to the other. My plan is, when I go to college I need a way to connect to my server. At home I can set a static IP for it, however at college I wont be able to do that. I'm not sure if the dual Ethernet will help, but my basically plan is to be able to connect to my server via a IP. That way I can set up host records, and also be able to connect to it via SSH.

There is an easier way to setup a remote connection but first, what OS is the home machine running? What OS is the machine at school running? Do you have a router at home?

I plan on having the server with me at school. I'm just trying to find a way to give it a static IP of sorts. That way I can just have it sit in the corner of the room and I dont have to bother to lookup the IP on it every time I want to connect to it viva SSH or access apache.

You still didn't answer the question of what OS will be running on the server but either way, take a look at dyndns.org, GoToMyPC, or LogMeIn

Add zoneedit.com to that list; it's the one I use for this sort of stuff.

Let me clarify my question:

Currently I have my desktop, and my server. At the moment I can assign a static IP to it because I have complete control over my router. So when I want to connect to it via SSH I can just type in the IP and connect. For all my web programming, I just edit my host file and put some dummy domains in usaly ending in .dev. This works perfectly because I don't have to worry about my IP changing and I never have to update any files.

However, at school, if I were to connect both my desktop and server tot he network. The IP would not be static, but dynamic, because I have no control over the router. So if I wanted to connect to my server I would first have to hook a monitor and keyboard up to it, check the IP and then I could connect. This kinda of defeats the purposes. Also every time my IP changes I would have to update my host file with the new IP.

So here is my question. Can I use my second ethernet jack to connect to my server with a `static IP` of sorts. All those services are great if I were to leave my server at my house, but I plan on having it with me at school, because I also store all my music and pictures on it.

I've never setup a static IP at the router. I usually do that by opening up the NIC properties and going into the TCP/IP settings. This is in Windows by the way.

If you are worried about your school using DHCP this is what I would do. Once the server gets its IP from the DHCP server I would do an ipconfig /all and write down the IP and DNS info and then enter it in statically. This is Windows of course.

I think you are thinking about this too much.

Now I understand what you're trying to do. The problem is that most college dorms only have one jack in the wall for each student. If that's the case, you can't have 2 PCs there because, your IP is already an internal IP and you can't split it any further.

I would leave the server home and use one of the services I suggested.

For the 3rd and final time, I am asking you, WHAT OS IS THE SERVER RUNNING?

lol, sorry, I thought I added that.

CentOS 5

Ok. Either try to get one of those services to work with CentOS or put the PC in the DMZ and test the connection from a friend's house.

If you take the server with you, it will be more of a problem.

Another choice would be, put all those files on an external HD and take that with you.

Wow some great utility recommendations in this thread. Thank you!

I don't think this is correct. If you go buy a $50 router, you could static your 1 IP (as WAN) then subnet in your room.

How is the college router going to read that?
You're telling him to change a LAN into a WAN.

that's how you set up subnets...

Suppose the college subnet is 192.168.0.xxx and it gives him an IP of 192.168.0.22, how can his router subnet that any further without causing an IP conflict?
