First, the non-persistent method to assign an IP address and default gateway, which means your configuration will be temporarily assigned and can be lost once you restart the networking service! Figure-1 shows an example where no DHCP server exist to assign an IP address to Kali Linux, the following commands have been used manually bring up eth0 (network interface). Sep 07, 2018 I want to show you how to use Netplan on Linux, to configure a static IP address and a DHCP address. I’ll be demonstrating on Ubuntu Server 18.04. I will give you one word of warning, the.yaml files you create for Netplan must be consistent in spacing, otherwise they’ll fail to work.
I am a new with Linux, having years experience with Windows servers/desktops and am having issues setting a static IP. I am using a method used for previous versions of Ubuntu, which doesn't seem to work with 16.04
I have used the command
sudo nano /etc/network/interface
and added the followingI have rebooted the system and the Ethernet is pretty much dead, ping doesn't work at all. I have tried to modify
/etc/NetworkManager/NetworkManager.conf
and made the following changesWith this I can get Ethernet to work sporadically, however it eventually fails.
I have tried this configuration on two other machines plus a virtual machine as well and all have the same results. I can confirm these settings work fine when I install Windows on any of these machines.As well when I let DHCP auto configure, everything works fine no issues.
I figure I am missing something here, setting up a static IP should not be difficult at all.

I had the same problem and this was my solution:
and paste (altering for your network) this under
# The primary network interface
:You can get correct interface name using Terminal command
ifconfig -a
on ubuntu 16.04 or ip address
on 18.04+Shutdown your Virtual Machine and then!!!Go to network settings and click on refresh MAC address button a few times :)
and start your VM and you should get internet!
UPDATE 20.02.2019
For ubuntu 18.04+ you need to edit this file

Setting the static IP address as above in the accepted answer here works, but one has to flush the old IP addr setting and then restart networking.service:
Then verify it is correct:
GrantGrant
sudo vim /etc/network/interfaces
sudo ifdown eth0 && sudo ifup eth0

I had the same problem and the solution 'was' simply... for me, at least.
And, create an empty file with the name of the network interface in:
It works...

I used to set static IPs on my Ubuntu machines and then I noticed that I can just assign the IP address using my router. This may be the simplest solution. Just log in to your router, find the attached devices, and assign the IP address there.

If your server is showing that old IP as well as new assigned IP, simply restart your server. It will automatically flush old IP and persist the new one.
And if you don't want to restart your server, use this command:
And if you don't want to restart your server, use this command:
sudo ip addr flush <your-interface-here>

I am using Ubuntu 12.04.
My

file consists of: I ran the command:
/etc/init.d/networking restart
Which responded with:
Next I ran ping google.com and received:
I am not sure if my interfaces refreshed. How do I properly configure my network with my static DNS addresses?

As the questioner gives the contents of his
/etc/network/interfaces
I infer that he is using ifup to configure interfaces. But since he may actually be using NetworkManager, I will discuss that as well.If you are using ifup then DNS settings go in
/etc/network/interfaces
. For each interface you add dns-*
options appropriate for the nameserver(s) available over that interface. E.g., if a nameserver at address 1.2.3.4 is available over interface eth0, then add dns-nameservers 1.2.3.4
to the iface eth0
stanza.If you are using NetworkManager then settings are entered in the Connection Editor (network indicator | Edit Connections...) in the IPv4 Settings tab.
Doing
/etc/init.d/networking restart
to reconfigure interfaces is deprecated. If you are using ifup
then first ifdown
each active network interface, then ifup
each interface. If you are using NetworkManager then, first, disable networking using the indicator (top of the desktop); then open a terminal and runand then enable networking using the indicator.
Or you can just reboot.
Regarding the fact that
/etc/init.d/networking restart
resulted inThis means that ifupdown thinks that
eth0
is already up. Use ifdown --force eth0
to cause ifupdown
to stop believing that it has already configured the interface.Regarding the 'deprecated' message, this message is no longer printed in Ubuntu 12.10 but you should still note that initscripts are 'on their way out'. To restart a service
jdthoodjdthoodfoo
, use service foo restart
or restart foo
. Note also that if you want to reconfigure your interfaces it is better to ifdown them one by one than to rely on restarting 'networking'.![Arch linux static ip address Arch linux static ip address](/uploads/1/2/5/5/125541507/726285377.png)

If none of the above work, keep it mind that Ubuntu appends a
tail
file to the resolv.conf file that it generates.Try this:
Which will open a blank resolv.conf.d file in the nano text editor. You will need to place your DNS server address on the first line of this file and remember to end the line with a carriage return (hit enter) as seen below:
Editing the tail file instead of the actual resolv.conf file will prevent your change from being lost upon a system reboot.
You will need to run
jdthoodsudo resolvconf -u
to activate the change. You should be able to ping google.com after this. Good luck! 10.6k22 gold badges4141 silver badges6363 bronze badges

Command line version:
You should add your nameserver(s) to

All of the answers which relate to /etc/network/interfaces incorrectly state
dns-nameservers
rather than dns-nameserver
- below should work:(tested on Ubuntu 15.04)

Easiest method of configuring your DNS servers is to use NetworkManager
Under IPv4, fill in your dns server(s)

I was able to work around this on a headless ubuntu server install by adding
...after the relevant interface stuff in /etc/network/interfaces:
Hope this helps later users!
corqcorq
Note: carefull using without direct access on the machine, this will cut the connection...
I use
then
It will reset and release everything...
If it faces with errors related to configuration, you can use:

This worked for me
and add:
Run:
I use core install of ubuntu server.

You are missing a subnet specification in the interfaces file.
Add netmask
jdthood255.255.255.0
to /etc/network/interfaces
below the network line.10.6k22 gold badges4141 silver badges6363 bronze badges

For some reason the
dns-nameservers
statement does nothing in my case. And the other answers are not by the book, as they bypass dnsmasq
as it is utilized in Ubuntu.To do this right, edit
/etc/dnsmasq.conf
Add your nameservers to the bottom of the file:
Restart dnsmasq to use the new settings:
sudo service dnsmasq restart

I had this problem. I thought i was going mad. Everytime i edited
/etc/resolv.conf
, it deleted my config. Turns out some total lunatic has distributed debian with network-manager, which is overwriting all my network settings. This is how i fixed it:
1)
sudo apt-get purge network-manager
This gets rid of this horrendous new tool that stops all the configs from working properly.
2) Edit the
/etc/network/interfaces
file:3) Edit /etc/resolv.conf:
4) Reboot.
Congrats, you now have sane configs that work again.

You might configure that interface in an other file too, since you have more gateways.
Details are here.
