I have created a new domain to track my studying http://LinuxFanBoy.com After 30 years of working in the computer industry I have decided to get certified. I'm studying for my RedHat Certified Engineer (RHCE) exam.
The RHCE is an all day, hands on test requiring the test taker to configure and trouble shoot Linux systems as directed by the examiner.
I have worked with Linux for ten years. I starting with version 0.98 and I have written Linux applications and kernel patches. I use Linux to run my own websites. I worked for large corporations with hundreds of Redhat Linux servers. You might think with all this experiences the exam should be easy. I don't want to risk the $750 cost to take the test.
 My study guide is the "Red Hat certified Engineer Linux Study Guide - Forth Edition" by Michael Jang. This guide is based on Redhat 3. The current RHCE test is given with Redhat 5. If anyone knows of a newer study guide, or is writing one, I'd be happy to buy or review it.
I'll be posting what I learn on this website, as I go along. I've learned you retain more if you read it, write it and do it. This website is where I'm writing it all down. If you find something wrong or if you don't understand something, email me at

I'm not going to cover every detail in the book. There are a lot of Linux commands I know by heart and so I don't need to study them. If you don't know vi, ls, ssh or tar already this website study along is not for you. I've read only 50% of the people taking the test pass. If you don't know these commands already you might want to take one of the expensive courses.
I'm also not going to follow the book page by page. There are a few things that will make studying easier. Installing Linux over a network is faster then using CDs. So on day one, I'm going to setup network installation.
The computer I'm installing RHEL5 on is an old ? with a ? hard disk, keyboard, mouse, network connection and monitor. I also have a second RedHat (Fedora Core 6) system to load the Linux installations CD's on. You will also need to get your hands on a set of Redhat Enterprise Linux 5 CDs. I got my copy from a friend at work.
Feel free to follow along and learn Redhat Linux yourself. Maybe I will see you at my testing center. |

 I have been waiting for years a computer security company to pull their head out of their ass and make a security device that's easy to use and cheap. It has happened.
MyPW is making a one time password token affordable to anyone for an affordable price.
Most people use the same or similar passwords for all they online accounts. There is almost no way anyone can guess your password because it changes very time you use this token. Every time you push the button on the key-bob it displays a new random number. You use this random number as your password. Anyone trying to guess your password has exactly a 1 in a 1,000,000 chance of getting it right. Add a password to this and the odd become fantastically high.
With a MyPW token you can access any MyPW enabled services and thousand of OpenID enabled web sites. Here is how it works.
When you login to a MyPW enabled website or one using OpenID, your password authentication request is redirected to a MyPW server. MyPW.com verified your random number and returns a good or bad signal back to the requesting process.
Let us say you have a Linux system at home and you'd like to access it from work. You know they monitor the office network. They could capture your network traffic and capture your password. You might even be using SSL to encrypt your data but if you don't check the ID of the certificate you get back you may be going through a company proxy and they are decrypting your traffic. This is legal because you are using their network.
Order your token. You install the MyPW PAM module. (I've had a little trouble getting this part done. You have to compile the code.) You then edit the file /etc/pam.d/xmlrpc.conf and add your ID and token info to the file. It will look like this.
mark mysite aslk1u401da2901 5999999 https://services.mypw.com/RPC2
After you compile and install the PAM Module you'll need to sign-up for our Free API access account and a Token or MyPW for your Mobile Phone. Now when you login using this account, your server will use MyPW to verify your password (the random number). If your anyone from your office tries to use the password it will not work a second time.
I haven't ordered a token from MyPW yet. I will. I have ordered a PayPal token for $5 and I'm guessing they are the same. I'm hoping PayPal and services like them wouldn't require you to carry around a token for each web service you use. This is what OpenID is all about. In a perfect world, I should be able to use one token to access all my accounts. This can be done today if everyone used OpenID as their login. |

 I love my Country.
It's the GOVERMENT I'm afraid of!
How the USA is become a police state.
Princeton University describes the term "Police State" as:
a country that maintains repressive control over the people by means of police (especially secret police)
http://wordnet.princeton.edu/perl/webwn?s=police%20state
The United States was founded to protect "Life, liberty and the pursuit of happiness" as described in the United States Declaration of Independence. These are considered "unalienable rights". However, today, I question whether these ideals still exist.
When I was young I trusted everyone as did most people. You left their home unlock, and car running on a cold day while they went in the store. (1950) These trusts died quickly. But some trusts continued. A Policeman could be trusted. (1960) When you where in trouble you called the police or hoped one would drive by. Today even the process of democracy it self, voting, is thought thought to be rigged.
Because trust is accepting power without fear. Trust can be betrayed. Today people feel betrayed and untrusted by those we have put in power.
