Error while configuring Linux snmp wizard

[dwhitfield]

What's the output of sudo find / -name snmpd.conf?

For clarity, did you use https://assets.nagios.com/downloads/nag ... g_SNMP.pdf for setting this up?

Hi,
For clarity, did you use https://assets.nagios.com/downloads/nag ... g_SNMP.pdf for setting this up?
=> No, I thought snmp was installed on the remote machine

I found snmpd.conf (attached).

[dwhitfield]

It looks like you did not perform the step of editing the snmpd.conf listed on page 2 of https://assets.nagios.com/downloads/nag ... g_SNMP.pdf

Based on the fact that you are not using the documentation, you may also need to run sudo apt-get install libsnmp-dev

[Frédéric GRANAT]

I performed the steps of page 2 and sudo apt-get install libsnmp-dev :

Code: Select all

[root@nagiosxi libexec]# ./check_snmp_storage.pl -H 172.16.1.19 -C Str0ngC0mmunity -m "^/$" -w 2 -c 4
ERROR: Description/Type table : No response from remote host '172.16.1.19'.

What's the output of the following?

From Ubuntu

Code: Select all

ps -A | grep snmp

From Nagios

Code: Select all

telnet 172.16.1.19 161

Also, you changed community strings in your examples. Was that intentional?

Hi,

Code: Select all

libriciel@iparapheurtestcd04:~$ ps -A | grep snmp
24306 ?        00:01:48 snmpd

Code: Select all

[root@nagiosxi ~]# telnet 172.16.1.19 161
-bash: telnet: command not found

Also, you changed community strings in your examples. Was that intentional?
=> Please tell me which example

[dwhitfield]

./check_snmp_storage.pl -H 172.16.1.19 -C Str0ngC0mmunity -m "^/$" -w 2 -c 4 vs. snmpwalk -v 1 -c public 172.16.1.19

Looks like you need to run yum install telnet and then telnet 172.16.1.19 161

[Frédéric GRANAT]

Str0ngC0mmunity is the community described in the document you told me to apply (Nagios XI – Monitoring Linux Using SNMP)
I applied the changes described in that document (p.2 and 3).

Do you think it's a wrong value ?

./check_snmp_storage.pl -H 172.16.1.19 -C Str0ngC0mmunity -m "^/$" -w 2 -c 4 is the command given in the same document to test snmp (p.6)

Code: Select all

[root@nagiosxi ~]# telnet 172.16.1.19 161
Trying 172.16.1.19...
telnet: connect to address 172.16.1.19: Connection refused

Str0ngC0mmunity is just an example we use in our documentation. You will need to be sure to change this to the community string your device is configured to use.

You will need to be sure to change this to the community string your device is configured to use.
=> I don't know what's the community my device is configured to use, where can I find it ?
