wpa in lenny

[memius]

my wireless network works at home, but i'm at an event, and i need access here. i've changed the essid and the key in /etc/network/interfaces, but when i run ifup -a i get 'invalid argument "key".

i'm sort of a noob at wireless. is there something sbvious i'm missing?

Install wpa_supplicant and create the configuration file like this

network={
ssid="<YOUR ESSID>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<YOUR PASSPHRASE>"
}

Then run this
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf

Changing the -Dwext and wlan0 according to your computer, you can get a list of drivers (-D) issue wpa_supplicant without options
