Proxy Configuration =================== If you have proxy in your environment, it will be necessary to add this configuration in your terminal. In order to do that, you can proceed as below: To check the current configuration .. code-block:: $ echo $http_proxy To setup your proxy .. code-block:: $ export http_proxy=http://SERVER:PORT/ or .. code-block:: $ export http_proxy=http://USERNAME:PASSWORD@SERVER:PORT/ And if you would like to keep it permanent .. code-block:: # echo "export http_proxy=http://proxy.local.domain:3128/" > /etc/profile.d/http_proxy.sh Note. Please, change the values according to your environment. After that, you should be good to go and use the ``crhc`` with no problems.
