For someone in my line of work the Hosts file on a windows system has been essential in some cases. In short the file works as a DNS just for my computer. This means that I can use file to change the destination ip of a certain address. As an example I can change http://www.google.com to point to 127.0.0.1 or whatever if I want. All I have to do is add the ip and url in my host file and then clear the cache by opening a command promt and typing "ipconfig /flushdns".
I have now set out to do the same thing on a Mac and this is how it is done:
- Open a terminal window
- Type "sudo nano /private/etc/hosts"
- Enter administrator password
- Do the changes you want to the hosts
- Press ctrl-X to save and confirm this and then ENTER to confirm saving
To try this out you can type "ping www.google.com" and check what ip the answer to the request comes from.
thanks for sharing!! very useful info :)
