Syntax Command Check_netstat_conn

[ednaldojta]

I already created a Nagios user on the remote machine. Below them as they are the permissions of files and SSH or file that I want to run on the remote machine.

I ran into a similar issue when I tested this. From the .ssh folder, run chown nagios:nagios . - this should fix it.

Also - just to verify - did you set a password for the nagios user on the remote machine?

Let me know the result.

Good morning mate!
I did the following step-by-step.

I created a Nagios user on the remote machine and set a password for it.
I could not carry out the execution of the command
"Ssh-copy-id ~ / .ssh / id_rsa.pub [email protected]" because the result of this command is as follows:
ssh: Could not resolve hostname /home/nagios/.ssh/id_rsa.pub: Temporary failure in name resolution
So I copied via scp to id_rsa key, id_rsa.pub to the remote machine.
Since then I can not connect via ssh Nagios (10.10.60.51) to the remote host (10.10.60.52) with Nagios user of the remote machine.
However I can not perform the check via check_by_ssh, reports the following message.
Critical - plugin time out after 10 seconds
[email protected]'s password:
[email protected]'s password:


Note: I already realized chown nagios: nagios /home/nagios/.ssh
and also in the file.

is to solve this friend? Help me.

Here's what I did:

1. Copied the "check_netstat_conn.sh" script to the "/usr/local/nagios/libexec/" directory on the remote box.
2. Copied the public key from my XI box to the remote machine as "authorized_keys".

Code: Select all

scp id_rsa.pub [email protected]:/home/nagios/.ssh/authorized_keys

3. Made sure the permissions of the files in the "/home/nagios/.ssh" directory on the remote machine are correct. Here's what I have:

Code: Select all

ls -la /home/nagios/.ssh
total 20
dr-xr-xr-x  2 nagios nagios 4096 Mar 11 10:30 .
dr-xr-xr-x. 5 nagios nagios 4096 Nov  9 11:30 ..
-rw-------  1 nagios users   410 Mar 11 10:30 authorized_keys
-rw-------  1 nagios users  1671 Nov  9 11:30 id_rsa
-rw-r--r--  1 nagios users   410 Nov  9 11:30 id_rsa.pub

4. Tested the passwordless log in to the remote machine from the Nagios XI server.

Code: Select all

su nagios
[nagios@localhost root]$ ssh [email protected]
Last login: Fri Mar 11 10:35:20 2016 from y.y.y.y

[nagios@localhost root]$ /usr/local/nagios/libexec/check_by_ssh -H x.x.x.x -C "/usr/local/nagios/libexec/check_netstat_conn.sh"
OK: 5|count=5

Hope this helps.

Then the nagios user sets the remote machine is no password?

Then the nagios user sets the remote machine is no password?

The Nagios user will be logged in without being prompted for a password. This is typically referred to as key-based auth. https://www.digitalocean.com/community/ ... nux-server

Good morning friends!
I managed to perform SSH connection without password with Nagios User.
Now when I run the plugin / usr / local / nagios / libexec / check_by_ssh - H 10.10.60.52 -C "command" the following message appears.

CRITICAL - Plugin timed out after 10 seconds

what's up?

[ednaldojta]

Updating, I managed to perform the verification via ssh, as in the picture attached. However I just can it starting CLI, when I set up the command in NagiosXI it returns me the following error.

NagiosXI
COMMAND: /usr/local/nagios/libexec/check_by_ssh -H 10.10.60.52 -C "/usr/local/nagios/libexec/check_users -w 5 -c 10" -t 120
OUTPUT: Remote command execution failed: Could not create directory '/var/www/.ssh'.

NagiosXI
COMMAND: /usr/local/nagios/libexec/check_by_ssh -H 10.10.60.52 -C "/usr/local/nagios/libexec/check_users -w 5 -c 10" -t 120
OUTPUT: Remote command execution failed: Could not create directory '/var/www/.ssh'.

Just to clarify - is this from the test check command? What is the actual result in the Nagios interface?

Looks like we're making progress!
