There are two default user accounts that come standard in the Digivance CXD network. The
“operator” account has access to the Digivance CXD binaries and is used for regular
maintenance. The “root” account has full access privileges to the entire file system. In
addition, the “operator” account has “sudo” privileges, which may be modified by the network
operator to tailor operator access. To learn more about “sudo”, log onto any Linux operating
system and type “man sudo” at the prompt. Note that, among other privileges, a “root” user
can create more user accounts on each node.
9.5 Using a Third Party Network Management System with Digivance CXD
Digivance CXD control and monitoring is executed via Simple Network Management Protocol
(SNMP). As such, any Network Management System (NMS) based on SNMP will be
compatible with the Digivance CXD system. However, not all NMS products are the same.
While it is up to the operator to determine which NMS is right for their needs, it is
recommended that the chosen NMS will have the following features:
• Auto-polling
• The NMS must regularly poll all nodes for MIB entry updates.
• The NMS must regularly search for new nodes on its network.
• Graphical User Interface for data display and manipulation
• At a minimum, a MIB browser capable of SNMP level 2 sets and gets, coupled with a
node map generator, would suffice.
• Ability to output poll data to a database for customizable GUI operations such as user
accounts and data sorting is strongly recommended.
• Trouble ticket generation
• The Digivance CXD system outputs a wealth of raw event information. It is up to the
NMS to determine what alarms are generated, and how to dispatch resources to rectify
the situation.
• E-mail, pager, and cell phone notification methods are recommended for a user-
defined subset of fault conditions.
• Scheduling tables are a plus for those operators who are not on call 24 hours a day.
Note: The CXD Element Manager System (EMS) may be used to control and monitor the system.
10 CONFIGURING THE HUBMASTER NODE
A correctly configured Hubmaster Node is required to operate a Digivance CXD network. To
simplify this task, the Digivance CXD system software includes the configure-hubmaster
script. The use of this script is described in Section 10.1. In addition to the common node tasks
throughout this document, the Hubmaster has the following responsibilities:
• Network Timing Protocol Daemon (/usr/sbin/ntpd), synchronous with GPS input.
• Dynamic Host Configuration Protocol server (/usr/sbin/dhcpd3).
