Interestingly enough hostapd does not seem to work with tee. For example
'hostapd 2>&1 | tee hostapd.log'
does not produce any output, neither in the logfile nor on the
terminal. Anyone got an idea what the problem is?

Workaround:
'hostapd 2>&1 > hostapd.log' in one terminal and 'tail -f hostapd.log'
in the other to both write to file and get sort of live output on the
screen.
