Install SSH Server on Ubuntu Desktop

So you just installed the latest version of Ubuntu on your desktop. You want to access your spanking new Ubuntu machine from another computer. There are two ways in accomplishing this: (1) the fast and easy way via SSH, or (2) the slightly more difficult way via graphics called Remote Desktop.

Let’s say we go with the easy route in this article. We want to access it via SSH. I’ll follow up with another article how to access your Ubuntu desktop using Remote Desktop. So, we want to access your Ubuntu desktop via SSH. What we need is a SSH server. We can easily install OpenSSH Server by just installing the SSH server from the Terminal.

Install SSH Server

sudo apt-get install ssh-server

Done. Simple.

SSH Client

Your remote computer must have a SSH client to access your Ubuntu desktop. I recommend that you use Putty if you are a Windows users. Putty is a SSH client program to access your Ubuntu desktop. If you are a Mac or a Linux user, you can simply use the Terminal. Access your Ubuntu server by invoking the SSH client.

ssh 10.10.10.10

That’s the IP address of my Ubuntu desktop. You can specify a hostname if you have an internal DNS that’s working. You can also specify the username and the port number if you using a different port from the standard port 22.

ssh 10.10.10.10 -l username -p 2222

9/11 Remembered

Time flies. I can’t believe it has been 10 years since 9/11. I remember it vividly like it was yesterday. I had just woken up before 6am Pacific time. I went online to check my email and noticed that Yahoo was crawling. It was painfully slow. Yahoo’s home page eventually showed up after a couple of minutes. And there it was the top story. I don’t remember exactly what it said, but something similar to “Plane crashes into the World Trace Center.”

I immediately turned the TV on. Moments later, I saw the second plane hit the second tower. I also saw both towers collapse. I reluctantly showed up at work at 1pm. I was angry, dazed, and confused. It was a day that forever changed our lives. We lost loved ones. We also lost a large part of our freedom that day. We do things a little differently now, when we fly, and when we cross our borders. That was 10 years ago.

We moved on. And we must, but we should always remember 9/11.

HTML5 Basic Template

If you are going to be creating websites, you might as well be using HTML5 now. There is no point of using the older, antiquated, and sometimes verbose HTML 4 markup. A case in point, take a look at the HTML4 header markup below. It’s long, cryptic and hard to remember.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Compare that to the HTML 5 header markup below which is much, much simpler.

<!DOCTYPE html>

Let's take a look at the basic HTML5 template.

The HTML5 Basic Template

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>HTML5 Template</title>
<link rel="stylesheet" href="style.css" type="text/css" />
</head>
<body>
</body>
</html>

This template is perfect for creating quick websites, displaying example pages, or for testing purposes. If you want to create professional websites, then you should check out HMTL5 Boilerplate template which I highly recommend. It’s an excellent website to get you started with your HTML5 projects.
