![]() ![]() We recommended creating a connection for each hardware network device so that the NetworkManager connection binds to the hardware device's MAC address instead of the network interface name, even if the network device is not connected. This has been observed for network interfaces beginning with eth and bonded connections created from network interfaces beginning with eth. There is a known issue in CipherTrust Manager instances upgraded from 2.4 and earlier, where network device names sometimes swap MAC addresses after a reboot. Set a static MAC address for a connection You can configure a static IP address or DHCP so that CipherTrust Manager conforms to the way your network more broadly assigns IP addresses. That way, there are fewer IP addresses exposed for CipherTrust Manager network devices, and therefore fewer ways for potential attackers to reach CipherTrust Manager.īy default, CipherTrust Manager uses DHCP. We suggest explicitly disabling IPv6 unless it is required for your network. There is also a network configuration tutorial available for a simple set up without network interface bonding, VLAN, or static routes. This section details available settings and techniques to plan your network configuration. The remote connection will stop responding if the IP address settings are incorrectly configured, resulting in the remote machine being unreachable. Modifying a remote network interface over SSH is risky. Nmcli is available to the ksadmin user through the CipherTrust Manager appliance's serial connection, or the Virtual CipherTrust Manager's console. This configuration uses GNOME NetworkManager and its nmcli tool You can configure multiple network interfaces after installing and initializing a CipherTrust Manager physical appliance or private cloud Virtual CipherTrust Manager. ![]()
