Install non-trusted client side certificate =========================================== In addition to acting as servers in the DataONE infrastructure, Member Nodes also act as clients, initiating connections to other Nodes. When connecting to other Nodes, Member Nodes authenticate themselves in a process called :term:`client side authentication`, in which a client side certificate is provided over an LTS/SSL connection. Nodes that are registered with DataONE will only trust Member Node connections where a client side sertificate issued by the DataONE :term:`CA` is provided. However, a stand-alone instance of GMN will not connect to registered Member Nodes, so a non-trusted client side certificate can be used instead. These instructions use a non-trusted client side certificate for the first part of the install and describe how to upgrade the certificate to a certificate issued by the DataONE CA in the optional section on how to register the node. If you already have a client side certificate issued by the DataONE CA, you can still install the non-trusted certificate here and just follow the instructions to upgrade it later. Copy the previously created locally signed client side certificate for outgoing connections:: $ cd /var/local/dataone/certs/local_ca $ sudo mkdir -p ../client $ sudo cp client_cert.pem private/client_key_nopassword.pem ../client
