Nagios Support Forum

Hi all,

I am trying to set up SNMP on a Nagios server. I have installed the net-snmp package :

yum list installed | grep snmp
net-snmp.x86_64 1:5.7.2-37.el7 @base
net-snmp-agent-libs.x86_64 1:5.7.2-37.el7 @base
net-snmp-libs.x86_64 1:5.7.2-37.el7 @base
net-snmp-perl.x86_64 1:5.7.2-37.el7 @base
net-snmp-utils.x86_64 1:5.7.2-37.el7 @base
snmptt.noarch 1.4-0.9.beta2.el7 @epel

Edited the snmptrapd.conf file to include-

traphandle default /usr/sbin/snmptthandler
disableAuthorization yes

However when i try to start the snmptrapd service, it fails -

systemctl start snmptrapd

Job for snmptrapd.service failed because the control process exited with error code. See "systemctl status snmptrapd.service" and "journalctl -xe" for details.

systemctl status snmptrapd.service

Hi guys,

Would anybody be able to provide any advice/help with this issue.

Regards,

This time I am bale to see the below error in journalctl output

couldn't open udp:162 -- errno 98 ("Address already in use")
snmptrapd.service: main process exited, code=exited, status=1/FAILURE
Failed to start Simple Network Management Protocol (SNMP) Trap Daemon..

this looks like something is already bound to the address, what is the output of the following?

Thanks Scott

I was able to resolve the issue. Faced with another one now.

I can see the traps being sent from Fortigate, but I do not see any logs on the Centos Nagios server.

No related logs in nagios.log/ snmptt.debug/snmptrapd.log.

how about ?

Thank you Scott. I got this resolved.

It was more of an issue with the IPSEC tunnel.

Thank you
