Running 6-STABLE, it looks like hostapd_cli is trying to connect to a non
existent control socket. The hostapd socket for my ath0 interface looks
like the following:
ls -l /var/run/hostapd/
total 4
drwxr-x--- 2 root wheel 512 Jan 24 05:03 ./
drwxr-xr-x 12 root wheel 1024 Jan 24 05:03 ../
srwxrwx--- 1 root wheel 0 Jan 24 05:03 ath0=
Yet running hostapd_cli with any commands, such as 'hostapd_cli mib
dot11', seems to be looking for a socket named 'ath' (note the lack of
the 0). As viewed from strace:
connect(3, {sa_family=AF_UNIX, path="/var/run/hostapd/ath"}, 22) = -1
ENOENT (No such file or directory) close
My hostapd.conf is as follows:
interface=ath0
driver=bsd
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=-1
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel
ssid=Deadheaven
wpa=1
wpa_passphrase=<REDACTED>
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
The full strace file is attached. Have I misconfigured hostapd or
hostapd_cli somehow?
David
