LibreNMS VM Ubuntu 18.04 on VMware Player

Help
1

Hi everybody,

I’m quite new to Linux and running into an issue.

I think it’s a simple rookie mistake, I’ve searched the internet but can’t find a working solution.

After loading the LibreNMS OVA into VMware Player I can’t seem to get the network to work.

I can’t install any apps because of this, in this OVA the net-tools of nano tools aren’t installed, so how am I supposed to edit the interface config?

sudo open /etc/network/interfaces does nothing
sudo nano /etc/network/interfaces

So commands like nano or ifconfig won’t work.
Why haven’t these apps been added to the image?

Kind regards,
Tim

There is no ova built for VMware at this time.

Thanks for your reply, my bad.

It’s even in the description of LibreNMS.

At present we provide the following builds:

  • OVA Built with VirtualBox.

Just a FYI. In Ubuntu 18, default network manage is done via netplan: https://linuxconfig.org/how-to-configure-static-ip-address-on-ubuntu-18-04-bionic-beaver-linux

Well i have run into this problem and netplan did not solve the case. So what i did i assigned the ip address on the interface;

Adjust according to your interface

sudo ip addr add 192.168.99.202/24 dev ens18

That assigns the ip address to the interface. Then state the interface status;
for our case we are setting it to up.

**ip link set dev ens18 up**
ip link set dev ens18 down

now to verify our ip address on the interface;

sudo ip address show dev ens18

configure a default gateway

sudo ip route add default via 192.168.99.2

To verify your default gateway configuration

sudo ip route show

If you require DNS for your network configuration, you can add DNS server IP addresses in the file /etc/resolv.conf .

nameserver 8.8.8.8
nameserver 8.8.4.4

If you no longer need this configuration and wish to purge all IP configuration from an interface, you can use the ip command with the flush option as shown below. Though this does not flush the nameservers. You have to go to the file /etc/resolv.conf

ip addr flush ens18

Hope it works

@KagwaiMaina
Netplan is the way to configure the network now on Ubuntu. Using it properly will ensure your configuration will survive a reboot of the server. Your proposition can be used temporarily to test a new config but will not survive a reboot.

i agree it but it was the only thing that could work. It did prove futile later since i couldn’t poll public IPs i dont know if it was a result of that. i just shelved that until i have a better understanding of librenms. I ran into the same with Librenms Centos 7 image. I am starting to think it could be a network issue on my end.
