Using an HTTP proxy

Many times we don’t have direct access to the internet and the use of an Proxy server is necessary, to configure the RedHat Subscription Manager through a Proxy execute :

subscription-manager config
      --server.proxy_hostname=proxy.certificationsnotes.com
      --server.proxy_port=8080
      --server.proxy_user=username
      --server.proxy_password=secret_passwd
