問題

When you take a snapshot or create a clone of a TIE Server, it results in errors and connection issues in the TIE Server after you deploy it and turn it on. The errors and issues that you might encounter are:

When the server starts, you see a failed status for Bringing up interface eth0: Device eth0 has different MAC address than expected.
In ePO, under Server Settings, DXL client for ePO, the connection state is not connected.
In ePO, the following error appears:

Unable to communicate with Threat Intelligence Exchange Server. Check status of the Tie server, verify that ePO is authorized to send 'Tie Service Operation' Topics and 'Tie Set Enterprise Reputation' Topics and verify that Tie Server is authorized to Receive the above Topics

原因

This issue occurs because VMware changes the MAC address of the Ethernet adaptor when a snapshot is taken or a clone is created of the TIE Server.

解決策

Change the MAC address of the network card:

Connect to the TIE Server with the root user and password.
Open the following file:

/etc/sysconfig/network-scripts/ifcfg-eth0

To reflect the new MAC address, edit the following line of the network card, as shown in the VMware vCenter:

HWADDR=<new_MAC>

Save the change and restart the computer.
