One simpler thing for quick running multiple instaces is giving multiple=20
configs to the hostapd. Hostapd supports it from around 2005. This would ru=
n=20
one instance of hostapd listening on all interfaces given in config files.
Manual way:
/usr/sbin/hostapd -P /var/run/hostapd.pid -B /etc/hostapd.conf=20
/etc/hostapd2.conf /etc/hostapd3.conf
Attached patch doesn't change default behaviour and adding multiple configs=
=20
into rc.conf:
hostapd_conf=3D"/etc/hostapd.conf /etc/hostapd2.conf /etc/hostapd3.conf"
makes it work with more interfaces.
More elegant would be one instance for every interface but restarting only =
one=20
interface would be done by hand or by additional logic in the rc-script.
