snmptd
Nimsoft SNMP-TRAP Daemon

The snmptd acts as a gateway from the SNMP "world" into Nimsoft.
Most network-devices, such as routers, switches, bridges and so on, are SNMP-driven. The devices will report error-conditions as SNMP-TRAPS, normally sent to a directed udp-port (162) somewhere in the network (usually to a management station such as HP's OpenView Network Node Manager or equivalent).
The snmptd will listen to port 162 (default, but is re-configurable), and convert the incoming traps according to profiles.
The snmptd may also act as a SNMP-TRAP relaying station, spreading the original SNMP-TRAP to one or more management stations.

Installation notes

Please make sure that ports used are free (UDP/162 is the default port).
You may do this by issuing the netstat -an command, and look for something like UDP   0.0.0.0:162.
If it is present, then something else e.g. OpenView, Compaq Insight Manager etc. is using this port.


When upgrading the probe from version 1.9x to version 2.00 or above, the probe will merge the SNMPv3 and SNMPv2 checkpoints on upgrade. If the checkpoints have same names in SNMPv2 and SNMPv3 sections, then the SNMPv2 checkpoint configuration will take precedence and the SNMPv3 settings will be overridden by SNMPv2 settings.
