I'm aware of that, and I did say that I didn't know of one.

I only use wpasupplicant on one machine that has a flaky wifi, which
doesn't get on well with iwd. (It's a 2004-vintage laptop.) I
configure/check/debug the wifi at the console. Waiting for X to drag
itself into existence before checking out the wifi would be a big
time waster. So I don't install wpagui, don't know what it does,
don't know how it does it.

Yes, thanks for the wishlist bug.

When the demise of wicd became apparent (wicd hides the need to know
anything about wpasupplicant), I looked around for a replacement, and
came across:

https://lwn.net/Articles/770991/

That article put a damper on my reading up on anything about
wpasupplicant for the time being. I've found iwd works nicely
in bullseye, but don't bother with the buster version (which
is way back in the iwd development cycle).

Cheers,
David.

So, we will have it as a limitation. However, it is long-standing and
wpa_gui has efficiently managed connections here for a non-root user
for some time, which is all I ask of it. I can live with it.

Maybe wpa_cli and wpa_gui will eventually become dbus-aware.

OK. I suppose that this should be the goal if the user is in the
netdev group (I hope that if the user can terminate the process,
then he can also restart it).

Well, the wpasupplicant package could provide a default config file
(most packages do). I've just submitted a wishlist bug:

So, that's a limitation. There is no such limitation with other tools
(iwconfig, nmcli, and in the past, wicd), which work as a normal user
without needing anything special.

It cannot allow that, barring the security bugs in wpa_supplicant.
It does give the user full control over a wpa_supplicant process though
(i.e. associate with arbitrary AP, terminate the process, etc).


> or Debian should have done that by default.

That's my option too, but wpasupplicant package does not provide
wpa_supplicant.conf by default.
README.Debian should mention that bit of configuration probably.

So is "iw dev ... info", which uses "modern" communication via

Because wpa_supplicant is not aware of GROUP=netdev. See my other

This is either overkill (with a security risk, e.g. if this can allow
the user to become root), or Debian should have done that by default.

I'm already in the netdev group (this was done automatically at Debian
installation time).

Actually, that's iwconfig that gives interesting information, such
as the current ESSID, and it doesn't need to be run as root either.
According to strace, it uses a socket and various SIOCGIW* ioctl
calls, e.g. SIOCGIWESSID. I suppose that this is a bit like

http://papermint-designs.com/dmo-blog/2016-08-how-to-get-the-essid-of-the-wifi-network-you-are-connected-to-

(the author also used strace on iwconfig to find the method).

This limitation does not exist. wpa_gui and wpa_cli are both capable
of being run as a mormal user.

The wpasupplicant documentation also provides a useful README.Debian.

That is the first step but is not quite sufficient. The supplicant
needs to be made aware that the user is in the netdev group. Un my
/e/n/i:

  # The id_str.
  iface home inet dhcp

  # The id_str. 
  # iface home inet static
  #  address 192.168.7.55/24
  #  gateway 192.168.7.1

  allow-hotplug wlx74ea3a93adab
iface wlx74ea3a93adab inet manual
wpa-roam /etc/wpa_supplicant/wpasupplicant.conf

In /etc/wpa_supplicant/wpasupplicant.conf:

  ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev

  network={
  ssid="MI5_Listening_Station_#666"
  psk="Secure"
  proto=WPA
  id_str="home"
  }

The wpa_supplicant daemon runs with dbus capability.

The OP wanted an X11 app, while iwlist and nmcli are just command-line
utilities (though one may want to write a script to show information
in an X11 app, a text terminal or something else?). But my remark was
mainly: the iwlist and nmcli utilities can get the information as a
normal user, so there is a major limitation in wpa_gui and wpa_cli.

First example they provide in wpa_supplicant.conf(5) shows the way to
use wpa_cli sensibly without being root.
One just needs to define a group for wpa_supplicant's control socket, like this:

ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev

Add a user to a netdev group and you're set.

> The iwlist and nmcli utilities don't need root to work correctly.

I don't know about iwlist, but nmcli uses dbus to communicate with
NetworkManager. From the security standpoint, such approach clearly
loses to the simple unix socket communication restricted by natural
POSIX permissions.

Then don't run them? You can put  wpa_cli status  into sudoers
so that it will only run with that command.

> The iwlist and nmcli utilities don't need root to work correctly.

Run them then? I wasn't aware that iwlist would tell the OP
which AP is the connected one.

I presume nmcli is something to do with NetworkManager, which
I've never installed. But, as I wrote earlier, "I would have
thought that the program by which you connect would be able
to show you all the information it, by definition, knows about
the connection that it set up."

For most machines, I now use iwd, like Celejar.

David.

For security reasons, I don't want to run them as root.
The iwlist and nmcli utilities don't need root to work correctly.

wpagui doesn't work at all for me. It doesn't show any adapter.
But wpa_cli doesn't work either:

Could not connect to wpa_supplicant: (nil) - re-trying

while "systemctl status wpa_supplicant.service" says that the service
is running.

No issues with iwlist and nmcli.

You are associating with a wireless access point. You must be using
wpasupplicant. Have you tried installing wpagui?

That suggest that wpa_supplicant is actually managing the connection.

I don't know of an app to do that. This command should tell you
what you need to know:

# wpa_cli status

That shoud give you the SSID, the MACs at each end, and so on.

I guess it does; I never checked as it runs fine with stumpwm but I
probably have gnome dependencies installed.  Sorry for the noise.

nm-applet works for me.  It doesn't show the network explicitly unless
you hover the mouse over the little icon so I don't know if this would
suit your needs.



Thanks!

You may try gkrellm with gkrellmwireless plugin
I don't use it some years, so it may be wrong answer.


hopefully it doesn't depend on qt as i don't use kde ( i use twm for buster)

It is DE-independed.



Thanks!

i try "gkrellm --plugin /usr/lib/gkrellm2/wireless.so"

it doesn't work as i have hoped for

I would have thought that the program by which you connect would be
able to show you all the information it, by definition, knows about
the connection that it set up. For example, with iwd:
