How to disable network configuration via GUI

[IOWA]

Hello all,

Somebody know how to disable network configuration from GUI? Or better switch it to "view mode".

Reason: From GUI we can change/configured a lot of options and featured (like MTU or VXLAN), but if will configured somethink from CLI and then view it from GUI, GUI will create interfaces.new file and remove all commands from your manual congfit it does not support (like MTU, vlan, VXLAN and etc).



Best regards for help!

hi,

you can press the 'Revert' button on top if you don't want these options changed.

you're not supposed to edit /etc/network/interfaces directly, instead use the /etc/network/interfaces.d/ directory for your "custom" changes.

Thank you oguz for reply!

Unfortunatelly i'm from "redhat world" and no so understand how it works in debian. Could you please explain and give some expamples for MTU configuration?

In the man interfaces i have found only this information:

By default, on a freshly installed Debian system, the interfaces file includes a line to source files in the /etc/network/interfaces.d directory.

basically, if you add a file in /etc/network/interfaces.d/ , it will be treated as if it's actually written in /etc/network/interfaces itself (when these files are sourced). simply add the wanted options like you did in the interfaces file

if you need generic information about network configuration in debian[0], check the link.
