Global ETH0 and Global Secondary ETH0 IP Addresses

[Brooks]

Hello,

When the VM for our Nagios installatation got configured we configured the ip address for one static ip address. I just noticed the following outputwhen I enter the command ==>ip addr show (Note these are not actual ip addresses - just using these 2 addresses as an example)

(below ip address is the static address I configured)
inet 192.168.10.30/23 brd (broadcast ip address) scope global eth0
(not sure how the below DHCP address got assigned)
inet 192.168.10.50/23


- The question is this a normal ip address configuration (static ip address for the website) or did I miss something during the configuration? I would like to use static for both.

Thanks,
Bob

Hello,
- The question is this a normal ip address configuration (static ip address for the website) or did I miss something during the configuration? I would like to use static for both.

I'm a bit confused about what you're asking. When you say 'website' are you referring to your Nagios XI? What do you mean by 'I would like to use static for both' - both what?

Can you post the full output of ifconfig for us to look at?

[Brooks]

yes, sorry about that. The nagiosxi web interface is the static ip address that I set during the installation. I was assuming that this would be the only ip address configured. But there appears to be 2 ip addresses. I'm just wondering how the 2nd address got configured. Both ip addresses get me to the webgui.

[Brooks]

I should display what the 2nd address shows:
(below ip address is the static address I configured)
inet 192.168.10.30/23 brd (broadcast ip address) scope global eth0
(not sure how the below DHCP address got assigned)
inet 192.168.10.50/23 (broadcast ip address) scope global secondary eth0


- So, how did the secondary eth0 get configured with an ip address?

[rkennedy]

I don't believe Nagios makes any changes to interface configuration, so I'm not sure how the 2nd address got configured either.

Was the system a fresh install? Is anything else on the machine?

Once again, can you please post the output of ifconfig for us to take a look at?

[Brooks]

the configuration was from a preconfigurable virtual machine (VMWARE) that I downloaded from the site. I followed installation instructions to get everything up and running. the ifconfig output shows only the 2nd address I noted

[Brooks]

disregard. I did a reboot and now I see the one static ip address from the command ==>ip addr show

- sorry for the false alarm. Not sure what I did (perhaps I triggered some action from the web interface that did something funky with an ip function).

You can close this case.

Thanks for the response.

Please run the following and get the information back to us:

Code: Select all

ls /etc/sysconfig/network-scripts/ifcfg-e*
cat /etc/sysconfig/network-scripts/ifcfg-e*

[Brooks]

thanks for the reply Jolson but i'm all set now. If I see this same issue again I will note some of the commands and post the output in another post.

Thanks again,
Bob
