Hi Ray,

I discoverd wifind some weeks ago and I like it ;-)

I had to change it for my needs. I am sending you a patch with some
explanations about the changes :


_ Allow the possiblity to have the wifi interface part of a trunk.
In that case, no dhclient should be run, it is ran as part of the
thunk.
_ Recognize 'csv' string like :
privacy,short_slottime,radio_measurement,wpa2,802.1x
The 802.1x was preventing the match of the regexp.
In the case of 802.1x, wpa_supplicant should be started ... so it
needs the 2 following changes.
_ Allow the 'wpaakms' setting
_ Allow the 'post command' syntax to fire actions like routing,
wpa_supplicant, ...


Here a configuration example I am using:
{
"if" : "iwm0",
"trunk" : "trunk0",
"wlan" : [
{
"nwid" : "MOBILE",
"bssid" : "a8:22:66:5f:e6:6a",
"wpaprotos" : "wpa2",
"wpaakms" : "802.1x",
"description" : "Kennedy",
"command" : "sleep 1; rcctl restart wpa_supplicant; sleep 4"
},
{
"nwid" : "C84824",
"wpakey" : "54535726",
"description" : "Ma et Pa"
},
{
"nwid" : "zobe",
"wpakey" : "papounet",
"description" : "My GSM hotspot"
},
]
}

Thank you,
Best
