wpa_supplicant Excessive Logging on Raspberry Pi

Friday, December 25th, 2015

Today I noticed there was excessive logging from wpa_supplicant on my RPI. Normally this is of course not a problem but if you run it on an SDC like I do it might wear the memory since there is a low limit on the number of times you can rewrite it (in comparison with a harddisk).

I think there is a parameter $IF_WPA_VERBOSITY that can be set somewhere (maybe in the network file) however I was not in the mood to spend time on it so I just changed the following code in /etc/wpa_supplicant/


WPA_SUP_OPTIONS="-qq -f /dev/null -s -B -P $WPA_SUP_PIDFILE -i $WPA_IFACE"

After that is seemed to have stopped. Need to do it again after an update/upgrade though.
