network configuration.

Hey,
I'm new to LinuxCNC and need some help with network configuration.
I'm running the 2.8 version.
I cant find any commands that work for me to change an IP address.
When I try some commands i get RTNETLINK answers: Operation not permitted 
Edit connections in the nm-tray 0.4.2 does nothing when I click on it.

Any advice would be greatly appreciated.  Thanks 

You have to use "sudo" before any system command in Linux.
And you should really change the nickname, publicly displayed e-mails will end up in tears sooner or later, especially if using Windows as OS.

I'm using sudo and I finally got it to change shortly after my post but it won't stay and won't save either.
Thanks for the reply, and the suggestions.

I will keep banging the keyboard with my head I'm sure something will happen. Hahaha

I have embedded keyboard keys on my forehead from doing that, did not help !
If you are using the older official LinuxCNC ISO, it came with WiCD network manager, it is pretty much useless, so change to network-manager or download the 2.8.2 version ISO, it should have it included although i did not test it.

Back to the beginning, why do you want to change an IP address?

Is this for networking, or to connect a Mesa card?

Yeah im trying to setup and configure a 7i95 board.
I have an automation pc using to run Linux cnc.
It has 2 nics. I can't set either one.
