3.4.5.3 NTP Clients
To allow authorization between the server and client, copy the ntp.keys file to the desired clients
and add the following two lines to their /etc/ntp.conf file.
• keys /etc/ntp/ntp.keys
• trustedkey (1 ... 65534) (Same # as above in 3.4.5.2)
NOTE: By default all keys are trusted. The "trustedkey" line is mandatory on both the client and
the server.
3.4.6 Simple Network Management Protocol (SNMP)
The ATS-6501 includes an SNMP agent to provide external monitoring of system status via a
Network Management System (NMS). SNMP is a protocol used by devices to share system
information with a SNMP NMS responsible for monitoring the status of multiple devices. When
polled by the NMS the ATS-6501 retrieves the desired system information and provides it to the
NMS.
3.4.6.1 Management Information Base (MIB)
The MIB files describe the structure of the management data of a device subsystem and are stored
on the ATS-6501 in the MIBS subdirectory of the FTP directory. They can be retrieved from the
unit via a FTP client (username: ftp, password: ftp).
3.4.6.2 SNMP2
The system supports SNMP Version 2c by default and the community string (-c) is tsc. The
Version 2 agent provides the ability to get status but does not provide SNMP trap or set
capability.
3.4.6.3 SNMP3
To enable SNMPv3, a read/write user must be created and then added to /mod/etc/snmp.conf.
SNMPv3 users are separate from the system users and new snmpv3 user with the appropriate
permissions must be created. The snmp agent must not be running for this step, you can stop the
snmpd process with service snmpd stop command.
service snmpd stop
Stopping snmpd.
Waiting for PIDS: 610.
net-snmp-config --create-snmpv3-user -a "my_password" myuser
NOTE: The SNMPv3 passphrases must be at least 8 characters long
