Beginning in early December, phasing in first in CD then D0 offline, registration of network devices will be required before any network addresses are issued. The most visible impact of this will be to those using the DHCP (Dynamic Host Configuration Protocol) service to get temporary addresses assigned. Since a large number of users of this service are visitors, you may be asked for advice even if you are not using it yourself. The key to help is to follow the one sentence advice above.
For those interested in details, here's the rest of the story.
This summer's "exercise" of tracking down machines reinforced the importance of having a contact person for all systems on the lab network for quick response in computer security emergencies. Assignment of network addresses has become so automated, particularly with the advent of Dynamic Host Configuration Protocol (DHCP) services, that many people don't realize they need to register network devices at Fermilab.
If the machine will be at FNAL for longer than a few days, the machine must also be registered in the permanent database, as temporary registration will only be allowed for a limited period. Permanent registration is accomplished as described below, and should become effective within one or two working days.
When this new registration service starts, machines with unregistered MAC addresses will be treated as transient systems and required to register each day. In the longer term, machines with static IP addresses may also lose their network access if their registration is missing, incomplete or incorrect.
If you need further help determining whether the machines you use are registered or how to prepare your guests for visits, contact your General Computer Security Coordinator.
