Orange pi PC -- can't set a static ip

[parsable]

Hi Everyone.  I expect I'm making a simple mistake here, but I'm pretty new to this and could use some help.  I am trying to set a static ip address on an orange pi pc running armbian Jessie 5.36.  I want a static ip to set up an nfs between multiple boards.  I've done this before on debian desktops, but this time I'm getting errors.  I have tried multiple ways (editing the /etc/network/interfaces, nmtui, nmcli) without success.

 

For simplicity, here's a version of what I'm doing.  I start with a clean install.  The Opi connects to my router fine.  I add and update all the packages I need, then use nmtui to change the name of the network connection from "Ethernet Connection 1" to "Ethernet1".  I try to set the static ip with this command:

 

nmcli con mod Ethernet1 ipv4.address 192.168.1.100 ipv4.method manual connection.autoconnect yes

 

This command does not produce any errors.  I reboot, and the static ip address does display on the boot screen and /sbin/ifconfig.  The problem is that any commands that need the network now give the error "Network is unreachable."  Route -n is not empty, so I think I have a route out, but obviously I'm missing something.  I can restore the network connection by setting the method back to automatic but as soon as I set it to manual I get this error.

 

Any ideas?

you got the same problem with the IP as I when using the Text-GUI of nmtui

For the IP add /24 to set the subnet (255.255.255.) because if you didnt append the /24 you got a subnet of 255.255.255.255 and this is only your Orange-pi

 

Additionally you should set a gateway!!?

How about the following?:
 

$ nmcli con mod Ethernet1 ip4 192.168.1.100/24 gw4 192.168.1.1 
$ nmcli con mod Ethernet1 ipv4.dns "8.8.8.8 8.8.4.4"

gw4 is you gateway (should be the ip address of your router)

Thanks, guidol.  I managed to get it working.
