How to edit the hosts file in Mac OS X – Leopard
Step 1 – Open the Terminal.app
Either by start typing Terminal on the Spotlight, or by going into Applications -> Utilities -> Terminal.
Step 2 – Open the hosts file
Open the hosts by typing on the Terminal that you have just opened:
view source
print?
1.$ sudo nano /private/etc/hosts
Type your user password when prompted.
Step 3 – Edit the hosts file
The hosts file contains some comments (lines starting with the # symbol), as well as some default hostname mappings (e.g. 127.0.0.1 – localhost). Append your new mappings underneath the default ones. Or edit one of the default values
You can navigate the file using the arrow keys.
Step 4 – Save the hosts file
When done editing the hosts file, press control-o to save the file. Press enter on the filename prompt, and control-x to exit the editor.
Step 5 – Flush the DNS cache
On Leopard you can issue a simple Terminal command to flush the DNS cache, and have your host file changes to take immediate effect: view source print?
1.$ dscacheutil -flushcache
You can now test your new mapping on the browser!
