"sudo cp / etc / hosts /etc/hosts.minbackup"
-Enter your password for your user account if prompted.
Replace citynetwork.se and www.citynetwork.se against your own domain in the following line, and copy the entire line except the quotes. Then paste it into the terminal window:
"sudo echo 22.214.171.124 citynetwork.se www.citynetwork.se >> / etc / hosts"
NOTE! Mac users must run the following command:
sudo - sh -c "echo 126.96.36.199 citynetwork.se www.citynetwork.se >> / etc / hosts"
