Here is a script to take the hosts from From http://pgl.yoyo.org/adservers/ and convert them to rules for Little Snitch.

Im trying to block outgoing connections from my mac cause sometimes im using my iphone as a hotspot, and i have a limited data plan. Dev c++ ubuntu 16.04. I also saw an app called radio silence and it costs 3 times less than little snitch, will it do the same job? (deny apps to have internet connection unless i want them to be able to connect)?

It has options to grab the entire list or grab new entries past a certain date.

  1. How to block Little Snitch from calling home and killing numbers:
  2. 1. The first step is to block Little Snitch with Little Snitch. Create two new rules in Little Snitch as below:
  3. a) Deny connections to Server Hostname http://www.obdev.at in LS Configuration. The address that will appear if you do it correctly is 80.237.144.65. Save.
  4. and the next is:
  5. b) Deny connections in LS Config to the application Little Snitch UIAgent (navigate to /Library/Little Snitch/Little Snitch UIAgent.app, any server, any port.
  6. 2. After that is done, open the Terminal (in your Utilities) and paste in:
  7. sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts
  8. (Hit return and type in your admin password). A TextEdit window will open behind the Terminal window. Command+Tab to it - this is your hosts file.
  9. 3. Place your cursor at the end of the text there, type or leave one vertical space and paste in the following:
  10. # Block Little Snitch
  11. 4. Close TextEdit, hit Command+Tab to return to the Terminal window, and paste in the following:
  12. sudo dscacheutil -flushcache
  13. 5. Hit the Return key and quit Terminal. You're finished now.
  14. 6. Easy, isn't it. If only everyone would do this, the developer would cease and desist from killing the number that you personally are using successfully on your Mac. At least until the next version is released…
