Every resource I have seen / used always say how to COPY or paste entries into wpa_supplicant.conf.
The question is
Is there a document actually explaining , in "5 W's" style, purpose these entries?
I am enclosing annotated entries in my wpa_supplicant.conf to illustrate my post questions.
This is an original with single network entry:
#default original /etc/wpa_supplicant.conf network={ ssid="mywireless" #psk="secretpassphrase" psk=7b271c9a7c8a6ac07d12403a1f0792d7d92b5957ff8dfd56481ced43ec6a6515 }
#temporary commented out
Now what is the purpose of this ctrl_interface and where did it come from ?
#ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
What are we updating and when ??
#update_config=1
Now for change - this is selfexplanatory #country=US
#network={
# ssid="testing" # psk="jim" # }
