You can also set a password to access to the server ``--password``.
Glances is ``IPv6`` compatible. Just use the ``-B ::`` option to bind to all IPv6 addresses.
If Glances server is not detected by the client, this last one try to grab stats using the SNMP protocol:
.. code-block:: console
client$ glances -c @snmpserver
Known limitation: Grab using SNMP is only validated for GNU/Linux operating system.
