Extend Wireless Range with AirPort Extreme

September 29th, 2008 | No Comments | Posted in Tutorial

Is your wireless network area just too small for comfort? Are you always walking your laptop just out of range? If you have an AirPort Extreme router, your problem can be solved by adding another AirPort Extreme to your network.

It is a simple matter of getting the settings right. For reliability and maximum range, I chose to “wire” them together, even though you should be able to extend them wirelessly.

I put my AirPort Extreme base stations at opposite ends of the house, making it easy to use our laptop computers anywhere in the house, with range to spare onto the back patio.

The trick is to make the second one (the one NOT connected to your DSL or Cable Modem) a “bridge” connection.

First, get the “main” base station set up and running correctly. Make sure you have enabled the encryption scheme of your choice (choose the most secure encryption algorithm that all of the computers on your network can connect to).

Once your “main” AirPort Extreme base station is running and all of your computers can connect to it, connect the “extension” AirPort Extreme to the first one. Mine are connected through a “Network Switch” (similar to the network “hubs” of a few years ago).

Set up the Internet Connection Sharing to “Off (Bridge Mode).” The Wireless Options should be the same as on the “main” base station.

Note: Name the network the SAME on both AirPort Extreme routers. Also, use the same password for both stations. This way, your computer can connect to either base station with only one “key” in the keychain. It worked for me.

Set up each base to choose its wireless channel automatically. 

When you are at one end of the house and move to the other end of the house, momentarily “turn off” your laptop’s AirPort:

and turn it right back on again:

It will find the base with the highest signal strength automatically:

Any questions?

USB727 on a Mac: How to Connect Using System Preferences

September 22nd, 2008 | 3 Comments | Posted in Tutorial

Connecting with the USB727 on a MacBook

If you are using Verizon Wireless’ USB727 to connect your MacBook to the Internet, it is easy to connect using system preferences. But before connecting, you must download and install Verizon’s VZAccess Manager software. The latest version can be found here:

Verizon Wireless Software Download Site (vzam.net)

Once you have installed the software properly, you do not need to use VZAccess to connect your MacBook. Instead, you can simply use System Preferences. The main reason I use System Preferences to connect is that VZAccess Manager takes over your network connections, and as long as it is running, you cannot use the built-in AirPort Wireless connection on your Mac. However, if you use System Preferences to connect, both are available simultaneously.

Before Step 1:

Make sure you have installed the software from Verizon Wireless. Get the latest available, especially if you are using Leopard (Mac OS X 10.5). Use the link above to get the latest software.

Step 1:

Click on the “Apple” in the upper-left portion of the OS X menu bar, then click on “System Preferences…”

Start System Preferences

Step 2:

Click on “Network”

System Preferences: Network

Step 3:

Choose the USB727 modem

USB727 Preferences

Step 4:

Press “Connect”

This is what you will see once you are connected:

USB727 Connected Successfully

 

Once connected, you can surf the ‘net, email, SSH, FTP, etc., all using the cellular connection you have just opened.

You can even share this connection with those around you.

To Share The USB727 Connection:

If you want to share this connection, I recommend creating an encrypted network using Mac OS X’s built-in Internet Connection Sharing. Instructions for creating an encrypted network can be found in another post:

MacBook Internet Connection Sharing

The USB727 has performed very well for me as I travel around the US. It is a great tool to have while at your local coffee shop, too. It works great on the MacBook Air. I detailed my experience in this post.

To Disconnect:

When you are done, simply press “Disconnect” and remove the USB727 from your Mac. It’s that simple.

Can a Business Blog Make Money?

September 9th, 2008 | No Comments | Posted in Business

Can a Business Blog make money?

The answer is … (drumroll please) … maybe. Of course that’s the answer. But why? There are so many factors to consider when determining the profit potential of a Business Blog. Let’s examine the issues and circumstances that surround a successful Business Blog.

What is a Business Blog?

We need to begin by describing a business blog. Remember that the word “blog” started out as “Web Log” and was shortened by common use. The origin of the “Web Log” or “blog” was mainly a Journal that an individual person would keep for himself or herself or for friends to be kept up to date.

Soon, astute businesses began logging the events of the company for customers to review. The added words on a web site were helpful for search engines to further refine the purpose of the site. Successful bloggers began tweaking their blogs to gain ranking in search engines.

As individual as businesses are, so are business blogs. For the small business, a blog can be narrowly focused on the products or services rendered by the business. Large corporations utilize blogs to introduce new products and services on a grand scale. Many companies regularly maintain several blogs simultaneously to cover the many facets of their organization.

So when it comes to monetizing the blog, the methods are diverse. The methods one uses for profiting from the business blog are as varied as the purpose and mission of the business itself.

Is your Business Blog about a currently operating business?

For example, do you already have a service or retail store that is up and running? Are you passionate enough about your business that you think people would read what you have to say about it? Is there really so much to say about it that you could write about fresh topics day in and day out?

Of course, if new products are introduced regularly, each introduction gives you a topic about which to write. A business blog that gives short snippets about new products can be a fresh source of information for your current customers. You will attract new customers as they discover your product descriptions, hopefully through a search.

Is yours the type of business that people are curious about the latest new thing? For example, do you always sell the latest cameras or other technical products? Your customers will be interested in having the latest information about new products. You should ask them to sign up for regular newsletters from your business.

Is your Business Blog about an interest of yours?

Do you have an interest in cars, or flowers, or sports, or computers? When you write about them, do people care about your opinion? Does your opinion add value to their experience? Could you write a regular review of your experiences? A business blog about a topic of interest to you might be able to make money through the sale of advertising. Your level of interest and desire to keep writing will help determine your level of success.

If you are passionate enough, people will catch your enthusiasm and regularly read what you have to say, sometimes more so when there is nothing (apparently) in it for you. (They may not even notice that you are selling advertising space). If you do not sell cameras, but review them and blog about them, your blog may have more authority with perspective buyers. You will have an authenticity that a camera shop owner may not.

Successful Business Blogs Are Current

Nobody wants to show up to a business blog and find out information that is stale. This is especially true in technical areas. Yesterday’s news is sometimes too old. Fortunately, you can keep the information in your blog fresh and up-to-date with a single paragraph. If your business blog is updated daily, you will have more credence than say, a blog that is updated once a month, or just a few times a year (yes, I have actually seen this happen).

If you get tired of your business blog, it could be because nobody is reading it. If it is not of interest to anybody else, maybe you should consider closing it down or adapting to the world around you. People might be more interested in aspects of your business that you have not considered writing about in your blog.

Don’t leave a Business Blog orphaned!

You know yourself that if you visit a blog and it has not been updated in a while, you might think that the blogger has gone on to pursue other interests. If that is the case with you, by all means, close down your blog! Either fold the posts into a current blog, or clearly mark each entry to indicate that the blog is left up for archival purposes, or in case somebody needed reference to it in the future. But if you have decided that enough is enough, and the blog is no longer worthy to be published, CLOSE IT DOWN!

Be sure that people know of your new site, or they might think that you have gone out of business altogether! Put clear links on each post to your new blog or web site. There is no shame in closing a Business Blog that has run its course. (That goes for personal blogs, too. I have seen many that haven’t been updated for months and a few that haven’t been updated for years).

Now. About Making Money on your Business Blog.

Business Blogging is all about driving traffic to your site, as well as retaining your own customers. It is about generating the kind of interest in your business that keeps people coming back to you for more of your products and services.

A good Business Blog will keep your business higher in the search engines that if you didn’t blog. It will also tell prospective customers that you are current, and that your products and services are fresh and new. Your Business Blog is one method of communication where the customer can browse your business without feeling watched.

As you drive traffic to your site, you either have a product to sell on the site, or a call to action to get your product or service from you in person.

Link to your own site!

Make the best of your blog by linking to the things about which you write. Your own site should be positioned to take advantage of the hard work that goes into blogging. As you business grows in products and services, each blog post should link to at least one page about that product or service.

Business Blogs Are Different From Personal Blogs.

A Business Blog is not the place to post pictures of your favorite pet. Why not? A Business Blog should not be cluttered with things that can be posted in another place. If it is really that important to you, consider linking to your personal blog. Customers and prospects that have such an interest can easily click over to your personal blog and browse to their heart’s content!

This is not to say that your Business Blog cannot or should not be personal. Not at all! A Business Blog that is all business is no fun, and doesn’t give your reader a chance to know you. What I am trying to convey here is that your Business Blog should promote your business, not your favorite hobby or pet. You can have it both ways. You can give your readers a chance to click a link to your personal side if they wish, all the while maintaining a level of professionalism that says that you are serious about your business or company.

If you are blogging for a corporation, be especially mindful of this concept. In this case, the Business Blog can be as personable as the company allows, but the customer would most certainly mistake your company for a one-person business if the blog gets too personal.

Regular Readers or Search Engine Traffic?

Personal blogs in particular tend to gather regular readers. People come by or read a syndicated version of these blogs regularly. Business blogs can have the same reader loyalty, if the topics are of sufficient interest. I know people that check technical sites daily for news. Other sites will depend on search engines for their readers. This is okay, too. Some blogs are more of a reference work.

So when it comes to monetizing the blog, the purpose of the blog and the source of readers will help you to decide which method is best.

So, Can a Business Blog Really Make Money?

It all depends upon the effort you give it. If you are willing to write fresh material on a regular basis, you will eventually get noticed. The experts encourage lots of patience (don’t give up too soon–it could take a year to get a following). Keep focused on your main topic and add new material daily, if at all possible.

Do This BEFORE You Install FreeBSD 7

September 8th, 2008 | 2 Comments | Posted in FreeBSD, Tutorial

Installing FreeBSD

First Things First

So you’ve decided to install FreeBSD. Great! Now go out and get a copy of Bryan J. Hong’s book, “Building a Server with FreeBSD 7″ before you do anything else! Especially if this is your first attempt at installing FreeBSD–even if you are proficient with Linux or any other variety of the UNIX-like operating systems.

If you are in a big hurry, buy the book from the publisher along with the PDF version (buy both–you will want the hardcopy version for your notes).

 

Building a Server with FreeBSD 7

Why this book? First, it has a very clear set of instructions for installing each component you will need to create a complete web server with email support, FTP capability, SSH and SSL support, all using the PORTS system. Second, the book is small enough to take with you when you travel, so if there is a problem back at home, you can refer to the book and see where all those configuration files reside on your server. Third, it is a great reference book for future server builds, and a great place to put your own notes for customizations you have made.

Very soon after you install FreeBSD on your first server, you will have the confidence to build a second or third (or more). As you start adding FreeBSD servers to your data center, you may want to install custom FreeBSD servers for special purposes. For example, you may want to build a stand-alone mail server, that only handles email for your domain and other domains, as well.

Next Steps

After you build your first server, you may want to customize it… making changes to certain features. You will want to install and customize many of the PORTS available, getting the latest FreeBSD software and tools for your server.

FreeBSD Starter Library

Your Library

A good starter library for installing and maintaining FreeBSD servers would include the following books:

  • Building a Server with FreeBSD 7, by Bryan J. Hong
  • Absolute FreeBSD, by Michael W. Lucas
  • Wicked Cool Shell Scripts, by Dave Taylor
  • The Book of PF, by Peter N. M. Hansteen
  • The Book of IMAP, by Peer Heinlein and Peer Hartleben
  • The Book of Postfix, by Ralf Hildebrandt and Patrick Koetter
  • BSD UNIX Toolbox, by Christopher Negus and Francois Caen

I have all of the above books in my library. I do not consider this list to be complete, by any means. But if you are just getting started, buy the first and second book first. Then, as your interests become more focused, check out the rest of the books in my list. You will be able to install FreeBSD and maintain your server with proficiency.

Note: I have written a post to catalog my Errata for Building a Server with FreeBSD 7.

Buy the book and follow step-by-step the instructions to install FreeBSD. You can go from zero to fully functional web server over the weekend!

Errata: Building a Server with FreeBSD 7

September 8th, 2008 | 2 Comments | Posted in FreeBSD, Tutorial

I have built a few servers following the instructions given by Bryan J. Hong in his very thorough book: “Building a Server with FreeBSD 7.” For anybody wanting to build a web server, mail server, FTP server, or just a local network server, this book makes the process as easy as possible.

No Starch Press, the publisher, has an Errata page for this book. I found some additional errors when I built my servers, which I document here. Please check the official Errata page on No Starch’s site, and make the following corrections to your copy of the book before building your server. As of this writing, the official Errata page does not include these corrections:

  • On p. 25, in step 6., before “cd /usr/ports” issue this command: 
  • touch /usr/ports/INDEX-7
  • On p. 46, just above step 2., the two commands should NOT include “.sh” and should be:
  • /usr/local/etc/rc.d/courier-imap-imapd start
  • /usr/local/etc/rc.d/courier-imap-imapd-ssl start
  • On p. 184, the directory link (the second command on the page) should be:
  • ln -s /usr/local/www/apache22/data www

Using the default settings and following the directions in the book, the above corrections should all work perfectly.

Note: I have written a post on installing FreeBSD. It covers a good starter library of books on FreeBSD.
