I want to set a static IP for the box -- and get rid of the DHCP crap. Could someone please point me where to start?
Ah, your using ubuntu 18. I was a bit quick of the mark :) I'm a debian guy but ...
If you have no *.yaml file in your /etc/netplan directory then you might not have any networking setup. If you have no networking setup, it might be you are not connected to your router by any means?
Yup, the /etc/netplan directory was empty. But, I had a working network. I guess without a .yaml in the directory, the network is defined by a full-on DHCP process.
But, taking in your comments below and some of the terse explanation I found in searching the interweb, I built a 01_netcfg.yaml and populated it ... then `sudo netplan apply`
`ifconfig` showed me I had my new, static ip. Then with trepidation, I rebooted. The network came up with my new, static ip. Success!
I can only guess what the difference between 01_netcfg.yaml, 55_netcfg.yaml 99_netcfg.yaml might be. In reading the man pages,I believe later ones can override options set in earlier ones. Too complicated by half.
To check your current settings, use 'ip a' and 'ip route show' at a command prompt. This will give you a view of you current setup, i.e. ip range and gateway etc, if you have any, which you probably haven't.
If not then create one as '99_config.yaml' with your specific details. If when you did the 'ip a' above, you got info, great, if not you will need to get the ip range info from your router. You could do this by setting up dhcp first (not sure why you don't want to use dhcp, it is easier). The yaml file for dhcp would be;
network: version: 2 renderer: networkd ethernets: enp3s0: dhcp4: true
where enp3s0 would need to be the device name returned by 'ip a'. probably the second stanza of that printout. Once dhcp is setup, you will know the network details you need to setup static addressing.
Your yaml file for static would be along the lines of (but not with the 10.10.10.0 ip range or the eth0 device name);
network: version: 2 renderer: networkd ethernets: eth0: addresses: - 10.10.10.2/24 gateway4: 10.10.10.1 nameservers: search: [mydomain, otherdomain] addresses: [10.10.10.1, 1.1.1.1]
Change the device name and ip details above to match your own. Or ask again when you know more details.
Thank you!
