SNMP error create device

[renanrdrigues]

hi,

I'm having an error when I try to register a device:




I have already installed and configured the SNMP service on the machine.

Can someone help me?

I used this tutorial:

If you are getting an snmp error from the cacti server. Then I suggest you try the following from the command line of the cacti box

Code: Select all

snmpwalk -v2c -c <community-string> <host-ip>

[root@cacti /]# snmpwalk -v2c -c cacti 192.168.0.7
Timeout: No Response from 192.168.0.7

What can it be?

<community-string> is the name I put there in the SNMP settings of this machine?

Your community string is step2/3 in your host configuration. If you are following this guide it will be public, more than likely

If you are getting no response. Then I would check that snmpd is running

Code: Select all

 
systemctl status snmpd

If it running then check to see if you can do that snmpwalk locally (you may need to install the tools), and if you can do it locally. I would check firewalls or selinux to ensure that it is allowing access through.

I was able to get response using the command:

snmpwalk -v2c -c <community-string> <host-ip>

And SNMPD status is active.
