This must be the third if not fourth time the syntax in wpa_supplicant.conf bit me - I don't learn easily! ;-)
The comments in the example configuration file installed with wpa_supplicant provided under /usr/share/doc/wpa_supplicant-2.6-r10/wpa_supplicant.conf.bz2 explain a Unix control socket for external programs (wpa_cli, wpa_gui, etc.) to access will be created in a (default) directory: /var/run/wpa_supplicant To set access controls for socket(s) which will be created in this directory you can define a GROUP in the wpa_supplicant.conf file, so non-root users may scan for APs and set passwords for them using cli/gui applications. A syntax is given in this file to explain how to go about specifying a GROUP name for managing the cli/gui interface: # When configuring both the directory and group, use following format: # DIR=/var/run/wpa_supplicant GROUP=wheel # DIR=/var/run/wpa_supplicant GROUP=0 # (group can be either group name or gid) # # For UDP connections (default on Windows): The value will be ignored. This # variable is just used to select that the control interface is to be created. # The value can be set to, e.g., udp (ctrl_interface=udp) Here's where things go a bit off-piste. There's an uncommented entry in the next paragraph specifying not an IP protocol, but a Unix socket like so: ctrl_interface=/var/run/wpa_supplicant Having read the above and more in the example file, I thought the way to define a GROUP would be to just add a single directive, e.g.: GROUP=users But this causes wpa_supplicant to fail complaining about my GROUP entry above. Fair enough, from what it says I should also specify the directory. So I copied and pasted verbatim: DIR=/var/run/wpa_supplicant GROUP=wheel Again wpa_supplicant fails to start complaining about the whole line I just added. :-/ So, I look at older wpa_supplicant.conf files of mine and discover the directive needed to specify a GROUP is: ctrl_interface_group=wheel which works faultlessly each time. Am I missing something here, or is the example provided for wpa_supplicant.conf incorrect/incomplete and merits a bug report? -- Regards, Mick
