Configuration setup
Example:
We define as initial user the username zabbixhlm. The following parameters need to be defined:
snmp_v3_security enable
snmp_v3_userid zabbixhlm
snmp_v3_auth_protocol MD5
snmp_v3_priv_protocol DES
snmp_v3_usm_access enable
snmp_trap_version 3
As user ‘nemadm’, edit /opt/nem/etc/snmpagent.conf and customize the following parameters:
snmp_v3_security | enable | # Turn on SNMPv3 security |
# Possible values: enable | disable | ||
# Default: enable | ||
snmp_v3_userid | zabbixhlm | # username setup within SNMPv3 security |
# Default is equal to: big_chief | ||
snmp_v3_auth_protocol | MD5 | # The authentication protocol to set for the snmpv3 user |
# Possible values: none | SHA | MD5 | ||
# Default: SHA | ||
snmp_v3_priv_protocol | DES | # The privacy protocol to set for the snmpv3 user |
# Possible values are: none | DES | 3DES | ||
# Default: DES | ||
snmp_v3_usm_access | enable | # Allow snmpv3 user access USM (user) tables |
# Possible values: enable | disable | ||
# Default: enable | ||
snmp_trap_version | 3 | # Define if send SNMPv1 traps or SNMPv2 Notifications |
# Valid values are: 1 (for SNMPv1 traps) | ||
# 2 (for SNMPv2 notifications) | ||
# 3 (for SNMPv3 notifications) | ||
# Default is : 3 |
As user ‘nemadm’, stop and restart the snmpd to load the new configuration:
# /opt/nem/bin/snmpstop
# /opt/nem/bin/snmpstart
In the FOXMAN-UN database, this will create dbdata domain='snmpv3Tables' the snmp initial user called zabbixhlm with the parameters defined in the previous step.
Furthermore, the
• authentication protocol pass phrase is: zabbixhlm
• privacy protocol pass phrase is: zabbixhlm
This user can be used to connect a HLM system and create other users.
For testing, install net-snmp-utils, then run as ‘root’ (sample command line):
[root]$ snmpwalk -v 3 -u zabbixhlm -l authPriv -a MD5 -A zabbixhlm -x DES -X zabbixhlm HLMserver:161 sysUpTime
snmpwalk: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (21841) 0:03:38.41
