Using Facebook authentication from a local machine

Simply put, the last step of facebook authentication works by redirecting the client browser to the url of the application with certain secrets to identify the user.

We can redirect all traffic going to a certain remote site to go to our own machine by editing hosts file. Assuming a facebook application is set to use the url hawks.hub43.com, add the following line to your hosts file:

127.0.0.1 hawks.hub43.com

The hosts file is at :

C:\WINDOWS\system32\drivers\etc\hosts

You can edit the file using any text editor. To make sure your updates are working fine, issue a ping command and make sure the results are as below:

E:\www\dev\basbosa>ping hawks.hub43.com

Now you need to make sure you are running basbosoa on port 80, something like:

node --debug app.js -p 80

Make sure no other programs are using port 80, skype uses port 80 you better disable that.
