Hello! Happy New Year, Guix Help!
I'd like to make my OS a bit comfortable for usual user.
I use only wpa_supplicant + dhclient without any utility that gives control over wifi to usual users.
And I want to give such a control by my own hands and your advice.
Wi-fi connection sometimes is loosing, and the way to reconnect is to restart hurd services.
I do it by root beautifully. I need to allow usual user to do this too.
With that task I also have two providers: wired ISP and Mobile ISP -
And I have such a script for choosing between them.
Attachment: wpa
So this script fulfill things of reconnection and changing wpa_supplicant.conf
very easy for root.
I want to allow to usual user just to run:
$ /wpa isp
and my script reconnect to wifi again.
I tried to give root privileges for user 'bob' to run script /wpa with this line in /etc/sudoers:
# cat /etc/sudoers
root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL
user ALL=(bob) NOPASSWD: /wpa
#groups bob
bob : users wheel video audio netdev
But I still have these error messages:
$ sudo -u bob /wpa isp
Connecting to ISP provider
cp: cannot create regular file '/etc/wpa_supplicant/wpa_supplicant.conf': Permission denied
error: connect: /run/user/1000/shepherd/socket: No such file or directory
error: connect: /run/user/1000/shepherd/socket: No such file or directory
^X^C
$
Please, what to do here?

I've added these additions to config.scm, thinking it will give effect:
(define %sudoers-specification
(plain-file "sudoers" "root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL
ALL ALL=(ALL) NOPASSWD: /wpa"))
....
(operating-system
...
(sudoers-file %sudoers-specification)
)
And reconfigured. And it works!
Note that must run it with sudo!
$ sudo /wpa isp
Connecting to ISP provider
Service networking has been stopped.
Service wpa-supplicant has been stopped.
Service wpa-supplicant has been started.
Service networking has been started.
Very nice.
My usual user works nice with wpa_supplicant now.
Thanks to draketo and his config example
