[svlug] real basic wireless access question!!

[Michael Cheselka]

Scan for open ESSIDs and sort by signal strength:

iwlist ath0 scan | egrep 'ESSID|Quality=|Encryption key:off' | tr -s '
' | tr -d '\n' | sed -e 's/ ESSID/\nESSID/g' | egrep off | sort -t= -k
2n

Join a WLAN:

ifdown ath0 ; ifdown ath0 ; ifconfig ath0 up ; iwconfig ath0 essid
'OpenEssid' ; /sbin/dhclient -1 -q -cf /etc/dhclient-ath0.conf -lf
/var/lib/dhclient/dhclient-ath0.leases -pf /var/run/dhclient-ath0.pid
ath0
