Why installed nagios plugins doesnt work?

[hsmith]

Is the only out put that it trhows me, like i said up

Error: Could not bind socket to interface eth0. Check your privileges

Is this the only error you have? The only output that it is giving you?

When i run the command ./check_dhcp, yes

[hsmith]

When i run the command ./check_dhcp, yes

I think this may be a compatibility issue between this version of CentOS and the check_dhcp plugin. Can you please try another plugin and see if you get similar results? I was able to replicate this on my properly configured CentOS 7.1 VM.

I was wrong. You need to use the -i flag to specify what interface you want to use.

Code: Select all

/usr/local/nagios/libexec/check_dhcp -i ens32

In this example you can see mine is named ens32

To find this, just issue the ip addr command.

OOh, i think it works!, it says now :

"CRITICAL: No DHCPOFFERs were received."

well i dont have a dhcp server and its correct dont you?,

very thanks men, to work it in the nagios web interface i need to put the -i enp0s25 (its my interface) in the check_command?

That should work.

To clarify, you don't have a DHCP server, but you want to set the check up anyway?

If you DO have a DHCP server, and the check is failing, it is probably firewall related. In which case:

Code: Select all

service iptables stop

Yeah was only for testing nagios plugins in my nagios server, if in one future ever need.

All right, makes sense.

Is there anything else we can do to help you, or am I all right to close this one out?

[Jessuzz94]
