Not in my country. The person who is giving the key just knows the name of the
network and the key. Any detailed question makes such person go sway to find
some help and return 15 minutes later saying that nobody knows what am I
asking about.
So, is there any TECHNICAL way to find out encryption settings of a given
network?
Maybe it's cheating to run OpenBSD on both sides but here's what I get.
NOTE: I'm pretty distrustful of wifi networks so I have *not* tested
this with any other wifi networks.
AP is a ral0 in my workstation at work:
jross@slony:/home/jross $ cat /etc/hostname.ral0
inet 172.31.16.1 255.255.255.0 NONE media autoselect \
mediaopt hostap nwid WCAA wpakey "WY Children's Action Alliance" \
chan 1
My little Acer netbook has an iwn. Here's what I get when I scan for
wifi networks:
jross@acer:/home/jross $ sudo ifconfig iwn0 scan
iwn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:21:5c:73:da:af
priority: 4
groups: wlan
media: IEEE802.11 autoselect (DS1 mode 11g)
status: active
ieee80211: nwid WCAA chan 1 bssid 00:11:50:63:33:f2 216dB

wpaprotos wpa1,wpa2 wpaakms psk wpaciphers tkip,ccmp wpagroupcipher tkip
I'm in the basement so it's no wonder there are no other networks to be
seen.
Then I make an /etc/hostname.iwn0 file, cutting and pasting the key from
the scan into the file:
dhcp NONE NONE NONE nwid WCAA \
wpakey \
0xecef1946509dd46ad0144a25dceb70286337096f71b2045793ff05c9871bbf8b \
wpaprotos wpa1,wpa2
and run /etc/netstart
jross@acer:/home/jross $ sudo sh /etc/netstart

(The bit about checking for modem and starting wifi connection are to
first look for my Virgin Mobile broadband modem and if it is plugged in,
use it and if it isn't found, fire up the wifi.)
