NCast PR-HD - Manual (Page 62)

NCast Presentation Recorder Reference Manual
If the proxy server requires a username and password for access, enter the password.
All changes to these network settings require a reboot of the unit. Press the “Update & Reboot” button when
all entries are complete and you have double-checked the correctness of these entries.
7.3.15. SNMP – Simple Network Management Protocol
The SNMP protocol is a widely used, industry standard protocol designed to monitor devices of all types
(e.g. routers, servers, switches, PC's, etc.) on a network. Commercial and open-source tools (e.g. Nagios)
are available to provide comprehensive reports on the health of units being monitored. Customers running
multiple PR-HD encoders may benefit from the use of SNMP to track the availability and performance of their
systems.
The PR-HD agent supports protocol versions 1, 2c and 3. The following MIBs (Management Information
Base) are included in this implementation:
SNMPv2-MIB
IF-MIB
RFC1213-MIB
IP-MIB
IP-FORWARD-MIB
TCP-MIB
UDP-MIB
HOST-RESOURCES-MIB
DISMAN-EVENT-MIB
NOTIFICATION-LOG-MIB
For security reasons and to prevent unwanted use and probes of your network it is advised to change all the
default settings in the SNMP configuration window to private, custom values.
7.3.16. Community String
In Versions 1 and 2c of the protocol the community strings identified sets of resources to monitor and some
of these resources could be “read-only” and some could be “read-write”. In most default installations of
SNMP the community string “public” is read-only and returns limited, basic information about the system
being monitored.
Use of Version 1 or 2c protocol is considered to be insecure as clear-text is used and this is easily
compromised.
7.3.17. Security Name
In Version 3 a “Security Name” is similar to a username on other systems. It identifies an authorized user of
the system.
7.3.18. Authentication Password
Authentication is performed by using a user's authentication password to create an authentication key to sign
the message being sent. The signing key is generated from a password that must be at least 8 characters in
length.
7.3.19. Privacy Password
