Quick Solution: Follow other instructions on the Internet, but make sure that your Mac’s Ethernet address is manually set to “192.168.2.1″ with a subnet mask of “255.255.255.0″.

The Whole Story

So I finally upgraded the router in my home to wireless.  I am too cheap to buy the wireless ethernet card for the Xbox (it’s about $50), and since my Mac (13″ Macbook, the Aluminum series) has both wireless and wired ethernet cards (all Mac laptops do), I figured I could save some money by using my Mac to connect my Xbox to my wireless router.  People have been doing this for a while; I didn’t come up with that brilliant idea, I just wanted to make it happen for me.

… pause for a few.  I will update this later.

23May2009 – actually, it seems that I have forgotten to update this.  Well, the quick solution is the key point, so if you check out other tutorials, add my quick solution to the things you try before you give up.

Quick Solution: Even if your username includes a mix of capital and lowercase letters, you should use all lowercase when using terminal.

The Whole Story

Not much to it: I was trying to ssh (Secure Shell) into my Ubuntu Linux box from Mac OS X Leopard, but was having some problems.

Install SSH on Ubuntu

1. Open Synaptic Package Manager.
2. Install ssh and openssh-server
   
   
   

Your Ubuntu may need to restart, and after it does, your ssh service should be running.

Log into Ubuntu with ssh

Using a terminal on another computer that is networked to the Ubuntu box, type ssh user@host, where user is your username on the Ubuntu box, and host is the ip address of the Ubuntu box.

My problem is that my username on my Ubuntu box included both upper and lower case letters, so I was typing my username with upper and lower case. Only use lowercase letters.

The server will then ask for your password. This is the password for the username on your Ubuntu box.

If you type in the correct password, it should log your in.
