Hi all,

I need to monitor our dhcp server and came to see the check_dhcp plugin.

However I'm getting this error when initiating the command:

nagios@tool:~/libexec$ ./check_dhcp -s serveip1
Error: Could not bind socket to interface eth0. Check your privileges...

But when I am on root, I get this:
root@tool:/usr/local/nagios/libexec# ./check_dhcp -s serveip1
OK: Received 1 DHCPOFFER(s), max lease time = 86400 sec

ls -als on check_dhcp:
76 -rwxr-xr-x 1 nagios nagios 72834 2009-04-27 13:06 check_dhcp

Do I need to do something like set permissions on serveip1 server?

Please advise.

Thanks!

Nagios Plugin - Check_dhcp

You can follow what the article says to do, but my recommendation is to use sudo as using sticky bits can possibly be a security risk.

I did the above steps but now getting this error in the Nagios page:

CRITICAL: Received 1 DHCPOFFER(s), 0 of 1 requested servers responded, max lease time = 86400 sec.

Please advise...

I got this working!

What I did was I created a separate check command definition and reinstated $USER1$/check_dhcp "IP ADDRESS"

Now Nagios is absolutely happy with this change. :-)
