Comments on Setting a static IP on Ubuntu: a beginner's guide

So "network 192.168.1.0" no longer needs to be specified in the interfaces config? I think I've always done that for some stupid reason (bad habit?).

Sorry but this is a bad howto..  

If you edit manualy, make sure you remove the resolvonf package.

second, remove the "network manager" package. if you dont do this, it will messup your config.

als no /etc/hosts check,,  if you switch from dhcp to static, you also must change the /etc/hosts to match your hostname and ip.

And in my options this should not be on the howto forge ( sorry, nice try, but this wil give you a very bad setup )

 

I guess is wrong to put dns-servers on resolv.conf. Ubuntu hold this also in the /etc/network/interface file, not? Thats why in the resolv.conf - file: DO NOT TOUCH

hello

 

network connection is managed by nm-connection-editor. /etc/network/interfaces is not used anymore.

Editing the resolv.conf file is a bit pointless because changes will be overwritten after reboot (as the message implied). You may want to stress this a bit more and show readers how to properly add nameservers in the /etc/network/interfaces:

iface eth0 inet static

 address 10.1.2.3

netmask 255.255.255.0

gateway 10.1.2.1

dns-nameservers 178.79.174.162

dns-nameservers 185.10.203.37 

 

I want a static IP when I'm on my home-office/small-office network, but I need a dynamic IP when I'm walk-about with my laptop.  I wish there was some way to automatically process:  IF SSID="string" THEN run("script").  This script could then do whatever based on where I'm connected.

The correct way to set DNS is NOT to modify /etc/resolv.conf that is also a link, so you broke things.

You have to add in /etc/network/interfaces a line like

dns-nameservers 8.8.8.8

in the eth0 section (i.e. below gateway line for instance)

thanks. the graphic interface worked for me .

I am trying to assign Public Ip address to mu Ubuntu PC. I already got connection from Public IP router. I am trying to assign Ip address: 199.33.115.224, subnet: 255.255.255.192, gateway: 199.33.115.193. But when i assigned the Address to network. It's show me the unmanaged network. SO, its not connected to network properly. Please, provide me a proper direction to assign public Ip address to my pc.

Thank you for help.

HI,

Looking at setting up a Raspberry-pi VPN network and surveying my network parameters - your commands produce the following.Although there is some common ground, there is also considerable difference. Please advise:

Why should we configure another IP for same interface ? Will it be helpful in case of ipadress conflict e.g. say I switched on my laptop and there is some other network connected device like mobile which has already aquired ip which I has mentioned as static IP for my laptop. Please guide and sorry for being novice in networking concepts .

Additional IP addresses are e.g. used for servers when you want to assign a dedicated Ip to a specific service or website or when you run multiple virtual machines on your computer where each virtual machine is connected to a different external IP.

Yeah, this would be great.  But I have to configure stupid yaml file.  

Which is not working.  WHY is so ******** hard to set a static IP in Linux?
