Setting Static IP Address

mascenzi

Hello,
New to the forum. I'm having some issues regarding setting a static IP Address running Ubilinux.

here's where I'm at.

The general information that I've found has said that by editing /etc/network/interfaces with an address, mask, and gateway it is all that really needs to be done. However, no matter what directions I follow it never uses the IP address I assign. It always defaults to the dhcp address.

here is the current configuration of /etc/network/interfaces

This file describes the network interfaces available on your system

and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

The loopback network interface

auto lo
iface lo inet loopback

The primary network interface

auto enp1s0
iface enp1s0 inet static
address 10.4.0.253
netmask 255.255.255.0
gateway 10.4.0.1

I also followed here https://linuxconfig.org/how-to-setup-a-static-ip-address-on-debian-linux with no success.

I've never attempted to make the changes with the GUI, as I need to make it work via the cmdline as I won't have access to the UI at all.

Anyone, any ideas????

Hi @mascenzi ,

Did you try to restart your service?
sudo systemctl restart isc-dhcp-server

Cheers!

Hi @Chetan

Could you try this adding your own IP and network?
Edit: sudo nano /etc/network/interfaces

Defining your own Network:
auto enp2s0
iface enp2s0 inet static
address 192.168.1.150
netmask 255.255.255.0

Edit: sudo nano /etc/default/isc-dhcp-server Add your network interface:
INTERFACES="enp2s0"

Restart dhcp server:

sudo systemctl restart isc-dhcp-server

Hi @Chetan,

Hi everybody.

Note that with Ublinux, the network is managed by ConnMan and you MUST set your network option onlu using the GUI. If you make modifications on the classic file_ /etc/network/interface_, the new settings are ignored by the ConnMan. The actual settings are stores somewhere else but I actually do not know.

If you want to change the network settings using the /etc/network/interfaces file, you must uninstall ConnMan with the command apt-get remove ConnMan. After that you are not able to configure the network using the GUI, but the file interfaces is the real file with all the network settings.

Furthermore it is necessary to create a file_ /etc/resolv.conf_ with a simple text editor (vim, nano, ...) including the dns of the system. This file is very simple and contain a row for each nameserver as in the following:
nameserver xxx.xxx.xxx.xxx
nameserver yyy.yyy.yyy.yyy

Reboot the system and everything works.

I experimented this and my system works perfectly.
