Ubuntu and Static IP Address
I'm trying to figure out how I can assign a static IP address to my default ethernet adapter eth0 - all attempts so far have been fruitless and ended up in frustration.
I am running Ubuntu 14.04.5 LTS on an NVIDIA Jetson TK1 ARM platform.
Ideally, I want the interface eth0 to assume an IP address such as 192.168.0.xxx as per our company network scheme.
Using network-manager, I've tried (and failed) to manually assign an IP address. However, checking with ifconfig reports an altogether different IP which appears to be DHCP assigned (the IP address changes very regularly).
I have tried un-installing network manager and using the /etc/network/interfaces file to statically assign an address to eth0 however following this, I get a lot of RTNETLINK answers: Network is unreachable errors and no IP ever appears to be assigned to eth0.
Why does network-manager not seem to work in this instance? I have a vino VNC server running on my Ubuntu TK1 platform and the only IP address which allows me to connect is the DHCP address allocated away from network-manager
Confused!
UPDATE
After re-visiting this, I'm no closer to figuring out what is going on.
What I have tried since the original message was posted:
- Disabled
network-manager
- Assigned an IP address on a different subnet to our company network so that the DHCP server cannot allocate it an IP address
- Set up a static IP address in
/etc/network/interfaceswith the following information
>
auto eth0
iface eth0 inet static
address 192.168.200.1
netmask 255.255.255.0
When I take the eth0 interface down and back up again, I see this static IP address assigned correctly. After a while, however, a lot of RTNETLINK answers: Network is unreachable messages appear and the IP address disappears from eth0

What you write seems strange indeed. I am running 16.04 where they went away from eth0 naming convention, but I do not know about 14.04. Anyway you might want to consider to add some more data to your question as ifconfig and error message printouts, interface file content or even a screenshot of your network manager configuration page.

setting up a static IP address can be done through the GUI in Ubuntu 18.04.
- Click your connection in top right menu bar.
- Click your connection and click
wired/wi-fi settings
- Click the settings icon on the
Wired/ Visible Networkssection. - In
addresses:
- for
address, you will need to enter the static IP address of your choice (eg.192.168.0.3). - set
netmaskto255.255.255.0. - set
gatewayto the IP address of your network gateway (most likely192.168.0.1, which can be found on your gateway page, navigate to your forward-facing IP (whatsmyip) to get to this page).
- for
- In DNS section, set this to your target devices current IP address (
192.168.0.x), also can be found by navigating to your external IP. - Next to DNS section, set the
Automaticswitch to off. - Click
Apply. - Disconnect internet, connect again and navigate to gateway settings, your device should now have adopted the static IP (
192.168.0.3) you set.
