HI,

I have got a weird issue.

I use windows and I have install the VM and turned it on to see that centOS doesn't allocate an ipaddress to the machine.

I get a 127.2.0.1 when I enter the command "ifconfig". Further this does not allow me to access the nagiosXI web interface on the browser.

what could be the issue
guidance please

Regards

Check your network settings - usually I put mine as bridged so it's visible to the rest of the machines on my network. You might need to run dhclient to grab an IP. See if that works and let us know.

Hi tmcdonald,

thanks for the reply

I am already using the "bridge adapter" mode and I also tried the "dhclient", but that doesn't solve anything

any other suggestions please?

regards

What hypervisor are you using?

Hi,

and how do I determine which hypervisor I am using,

I am using windows 10 and using a Oracle VM VirtualBox manager to run my CentOS

Oracle VM VritualBox is your hypervisor. Does your network have a DHCP server on it? Make sure your network settings for the virtual box include a Network adapter, that it is enabled, and that you have selected bridge mode as @donald suggested.

If you do not have a DHCP server on your network (the one your Windows desktop machine is on), then you will need to assign a network address to the box using CentOS tools to do so, or by editing /etc/sysconfig/network-scripts/ifcfg-eth0 appropriately.

Hi,

I am using the network adapter option in the network settings and the option is

Qualcomm Atheros AR9485 Wireless Network Adapter

and I checked for the DHCP server on my windows and when I type in the

ipconfig /all

I get

DHCP Server .... 1.1.1.1

and how do I edit the ifcfg-eth0... a little more insight please

regards

Usually all you need to do is open the file in a text editor (vi, nano, etc.), set the "onboot" value to "on":

Code: Select all

ONBOOT=on

save, exit, and restart networking:

Code: Select all

service network restart

Hope this helps.

I believe you are confusing Nagios XI with NRPE (an agent that you can install on a remote machine in order to monitor it via Nagios or Nagios XI).

Installing Nagios XI on Ubuntu is not supported yet. As far as installing NRPE, this is an old document...

If you want to install the Linux agent (NRPE + Nagios plugins) on Ubuntu, you need to follow the document below:
