Description Łukasz Stelmach 2012-09-30 19:49:59 UTC
Unlike openrc's /lib/rc/net/wpa_supplicant.sh neither wpa_supplicant@.service nor the default wpa_supplicant.conf configure the ctrl_interface. Without it is impossible to control wpa_supplicant with wpa_cli.

There seem to be two (at least) possible solutions:

1. Add ctrl_interface to the default wpa_supplicant.conf
2. Add -C option in the wpa_supplicant@.service file.

The former seems better since it works better with openrc's script when the setting is not at its default value.

Reproducible: Always

Steps to Reproduce:
1. systemctl start wpa_supplicant@wlan0.service
2. wpa_cli ping

Actual Results:  
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory


Expected Results:  
Selected interface 'wlan0'
PONG

~amd64 systemd-193 works as expected with proprietary wl.ko for linux-3.5.4:
 # wpa_cli ping 
Selected interface 'wlan0'
PONG
 # ping heise.de

linux-3.6.0 proprietary Broadcom wl.ko segfaults ... as such wpa_cli doesnt work. I cannot test.

I am afraid neither kernel nor systemd are problems here. It is wpa_supplicant of course if you don't configure your network interfaces from hotplug events with openrc net.* scripts. Which version of wpa_supplicant do you use?

Please also try with an updated system
