I used this guide to install Tor on amazon EC2 instance. I use python to access some websites, and I want to access those sites by a US IP. As it is mentioned here I added following lines to the etc/tor/torrc file, restarted Tor, and still I get random IPs from random countries.
ControlPort 9051
HashedControlPassword 16:H____mypasswordhash________H
ExitNodes {us}
StrictNodes 1
How can I force Tor to get IPs from specific country? Is it a problem because I am using Amazon EC2?
