where is static IP addr?

[dahni]

to literally answer your question:
i do not know where networkmanager stores these settings.
but you are right, they are not in the "low-level" config files.

however...

I do most work via putty, but was not able to setup the fixed IP there.

you mean command line?
networkmanager has a command line interface, accessible with

Code:

nmcli

and

Code:

nmtui

iirc.

hope this helps.
