Has this ever happened to you? You go into your favorite cafe (with free wifi of course) and order your coffee. Then, after paying for the coffee and maybe a muffin, you sit down and open up your laptop. To your total disappointment, the wifi connection doesn’t seem to have ANY internet connectivity! BLAST! What a waste of 5 bucks, right? Well, not necessarily…

At this point, you should ask yourself a few questions.

  • Am I connected to the Access Point?
  • Have I been assigned a private IP address?
  • Can I reach the Access Point via web browser?

So, let’s assume the answer to question number 1 is YES…I am connected to the access point with a good signal! Now I need to know if I have an IP address.

In Windows, open a command prompt and type:

ipconfig /a

…In Linux or Mac, open a Terminal and type:

ifconfig

There are other ways to find your IP, but these work just fine. The private IP address will likely look something like 192.168.1.xxx.

Next, take that IP and change the last part (xxx) to 1. For example, if it was 192.168.1.193, change it to 192.168.1.1. This is the gateway address. Now, let’s try entering that gateway address into a web browser. If you are prompted for a username/password that’s good news! That means that the Access Point has port 80 open and is running a web server to allow web based configuration. Look for a model number or company name in the window asking for a password. If it’s something like WRT54G, that is a Linksys and the default username and password are both: admin.

If you can’t get in with a default username/password, you should probably just move on…unless you want to try something more advanced of course. :)

Once you ARE logged in though, you can do some things to get the free wifi working again. Release and renew the public IP…reboot the Access Point. That combination will fix a lot of connectivity issues!

Have Fun!

 

Came across this funny Facebook conversation…I am not sure if it’s real or fake, but it’s definitely funny! I had to share it:

 

Hi Everone! I have been visiting a coffee shop a lot lately that offers free WiFi. I have been using the connection to work on various things. I wanted to make sure that my browsing had some encryption to avoid sending out plain text data, so I figured out how to route my browser traffic through an SSH connection! The method basically uses an SSH connection as a proxy for the browser.

You will need:

  • An SSH server that you can log into.
  • An SSH Client on the computer you are using.
  • A web browser.

The first thing we will need to do is connect to the SSH server. We will be using a special command flag when logging in in order to set a port and to avoid opening up an interactive shell. The command you will run is:

ssh -ND 9999 you@example.com

Replace “you” with your login name for the server and “example.com” with the address of the server. You will notice that after you enter your password, nothing will happen. It will just sit there. That is exactly what we want. Now, minimize the SSH client or Terminal window. Next, open your browser. I will show you the settings for Firefox, but the setup is more or less the same for other browsers.

In Firefox

Open your Firefox settings. In Windows, it’s in the “Tools” menu. In Linux, it’s in the “Edit” menu. In Apple, it’s in the “Firefox” menu. Once you have the settings window open, click on the “Advanced” section and then the “Network” tab. Next, click the “Settings” button next to where it says, “Configure how Firefox connects to the internet”. Select the option that says “Manual Proxy Configuration”. The only thing we change here is the SOCKS Host and the Port. For the SOCKS Host, enter “localhost” and 9999 for the port number. It should look like this:

socksfirefoxconnection

This is a very old method for setting up a SOCKS Proxy, but it works quite well. Please feel free to comment!

Why is everyone tweeting about twitter? What’s the big deal? Where did the idea come from that NEW technology must be GOOD technology? I understand social networking sites and social bookmarking sites, but Twitter seems to be so benign in comparison to it’s big cousins. I can see how using Twitter to feed other social sites can be usefull, but hardly NOBODY is using it for this. I can also see using Twitter as a means to publish the status of a server. In fact, I might even write a script that will post my server’s uptime and load to Twitter. But there hardly seems to be anyone using it for this!

Most of the people who are using Twitter use it for the most ridiculous things. They take a shower and tweet about it…they eat breakfast and tweet about it…they hate monday so they tweet about it. I understand the whole “Web 2.0″ trend, but at some point we have to say Web 2.NO!

In these times of economic recession, it is important to save every penny that you can. The internet, as you all know, contains a vast world of services and products. A lot of them can save you money! You probably know about most of the services that I’m going to talk about here, but many people still aren’t taking advantage of them. So here’s my top 5 money saving internet services:

5. Online DVD Rental

Companies like Netflix have changed the way we can rent movies. A lot of people are already using Netflix, but the real money saving potential of Netflix is the combination of the Watch It Now feature and canceling any home cable or satellite services that you have. With more and more movies available on the Netflix Watch it Now site, it is obvious that we can pull our Netflix plan back to the 1 DVD at a time minimum and take full advantage of watching movies on our computer. I can already hear all of my readers who use Linux groaning. That is because Linux isn’t supported by Watch it Now which sucks, but it is still a very cool feature for Windows users. With Watch it Now, you can watch as many movies as you want on your computer with no extra fees. If you have a supported device, you can even stream the Watch It Now movies directly to your TV! Some of them are even in HD.

4. Free TV Shows

By cancelling cable or satellite services, we can save at least $50 per month. You would be surprised at how many networks allow you to view their shows on their website for free! CBS, NBC, FOX (no Linux support), A&E, and many more networks have full episodes that are viewable online for free. There are also sites that have many different networks to watch all in one place such as WWITV.

3. IP Telephone

Services like Vonage use the internet to make phone calls. That’s only kind of cool though because they still want you to pay 20 bucks a month for it. Services like Skype allow users to make internet phone calls from PC to PC for free! They will also let you make PC to Phone calls for very cheap. Sign up for Skype! Get all of your friends and family to sign up too! Then you can save cell phone minutes by using Skype when you are near your PC. After a couple of months you will probably notice that you can pull back your minutes on your mobile plan which can save you some cash.

2. Online Retail and Grocery Coupons

There are a bunch of online coupon sites that are not very good. If you are patient, you can find some real deals on some of them though. I’ve had the most success with Wow Coupons which allows you to print coupons right from your computer for use in various retail and grocery stores. Remember, every penny that you save adds up over time!

1. Host Your Website At Home

This one isn’t for everyone. If you have a website that you host through a hosting company, you might be paying anywhere from a few dollars per month up to 40 dollars per month depending on the hosting company and features. If you have an internet connection with a high upload speed, you should really consider hosting your own site. It takes some work and some patience, but it feels great knowing that you aren’t forking out any money to that hosting company anymore! The best part about hosting your own site is that you can get all the features that you need for free! All you need is a computer that you are willing to set aside as a web server. For an operating system, you should use Linux because for web servers, it is much better than Windows and it’s free. I recommend CentOS or Ubuntu Server. There is a ton of information available on how to setup a web server using Ubuntu or CentOS out there on the web. Do some research and start your project. If you don’t have a static IP address you can use a service like DynDNS which lets you host a site without a static IP.

All of these services can really save you some money! By canning your home cable or satellite service, your home phone service, and pulling back your mobile minutes you can save up to $100 per month…or more depending on what you were paying for them! With Skype, the key is really to get your friends and family on it. I hope this list helps you save some money in these tight times. Good luck to everyone!

 

The web has become a wonderful channel for artists, photographers, journalists, and musicians to share their message with the world. Being a long time fan of comic strips, I often find myself searching the net for new web-comics to check out. I have found that a lot of them are horrible. In fact, almost all of them are not even the least bit amusing. However, a few great strips have emerged and here is my list of the 5 best web-comics on the internet.

5. We The Robots

We The Robots

We The Robots is a clever toon from the mind of Chris Harding. Harding has been an artist and an animator for many years now. We The Robots almost never fails to make me laugh.

4. Left Handed Toons

Left Handed Toons

At first, I wasn’t a huge fan of Left Handed Toons (by right handed people). Over time however, my opinion has changed. Their zany humor has grown on me. Whether or not others agree with this selection matters not, because I like it!

3. Cyanide And Happiness

Cyanide And Happiness

Cyanide and happiness is a daily webcomic that is drawn and written by several different contributors. Some of the humor is very dark and disturbing, which is nice sometimes!

2. xkcd

xkcd

This is another one that I didn’t like at first. It seemed very trendy and I was convinced it was only popular because it makes its readers feel smart. I now spend a lot more time reading the comic though and I like it more and more. The art certainly isn’t terrific, but the writing is top notch. With an emphasis on math, physics and technology, this web-comic has quickly become one of the most popular comics on the net!

1. Utopia Theory

Utopia Theory

Okay…Utopia Theory. I absoulutely love this comic. It is one of the only hand drawn web comics out there. Created by Tom Duffy and Wes Hill, Utopia Theory is usually single panel comics with a bit of a Gary Larson feel. The writing is original, the art is great…this is my favorite web-comic!

Well, that’s my list. If you disagree please feel free to send all email complaints to /dev/null

Thanks!

digg

Today (July 31, 2008) at approximately 11:44am Pacific Time, Digg.com, the popular social bookmarking site temporarily went offline for some server maintainance. At approximately 11:45am Pacific Time, a Digg user who has been desperate to get a few diggs decided he would blog about the outage and then submit the story to digg.com. It wasn’t until he had finished his blog and tried to submit the story that he realized that the site needs to be up in order to submit a story. Better luck next time digg noob!
