Description Marc Gallagher 2005-01-04 00:07:50 UTC
My wireless setup uses a key containing spaces, which causes the following output when running the init script: 

/lib/rcscripts/net.modules.d/iwconfig
 * Starting wlan0
 *    Configuring wireless network for wlan0
 *    Trying to force preferred in case they are hidden
/lib/rcscripts/net.modules.d/iwconfig: line 340: iwconfig_get_essid_var: command not found
 *    wlan0 does not support setting keys
 *    or the parameter "mac_key_" or "key_" is incorrect
 *    Failed to associate with any preferred access points on wlan0
 *    Couldn't associate with any access points on wlan0
 *    Failed to configure wireless for wlan0

problem #1: iwconfig_get_essid_var is undefined! :)

Problem #2: my /etc/conf.d/net file contains a line like:
key_MyEssid="s:my wacky key"

lines 338-344 of /lib/rcscripts/net.modules.d/iwconfig contain:
e=$( iwconfig ${iface} key ${key} 2>&1 )
if [[ -n ${e} && ${key} != off ]]; then
    ##snip Error handling
    return 1
fi

and if I stick in an echo to see the contents of $e it prints:

Error : unrecognised wireless request "wacky"

I hacked around the problem by adding quotes around ${key}, so that line 338 becomes:
e=$( iwconfig ${iface} key "${key}" 2>&1 )

This will probably break for people who use stuff like:   key_ESSID1="s:yourkeyhere enc open"

----

/etc/conf.d/wireless - In my setup, MyEssid is hidden

config_MyEssid=( "dhcp" )
key_MyEssid="s:my wacky key"
dhcpcd_MyEssid="-N -t 10"

associate_order_wlan0="forcepreferred"
preferred_aps=( "MyEssid" )


Reproducible: Always
Steps to Reproduce:
1. Create an essid with spaces, e.g. key_MyEssid="s:my wacky key"
2. Force MyEssid to be chosen
3. start the wireless script

Actual Results:  
 * Starting wlan0
 *    Configuring wireless network for wlan0
 *    Trying to force preferred in case they are hidden
/lib/rcscripts/net.modules.d/iwconfig: line 340: iwconfig_get_essid_var: command
not found
 *    wlan0 does not support setting keys
 *    or the parameter "mac_key_" or "key_" is incorrect
 *    Failed to associate with any preferred access points on wlan0
 *    Couldn't associate with any access points on wlan0
 *    Failed to configure wireless for wlan0

Expected Results:  
results with my hack:

 * Starting wlan0
 *    Configuring wireless network for wlan0
 *    Trying to force preferred in case they are hidden
 *       wlan0 connected to "MyEssid" at 00:90:4B:31:7D:C8
 *       in managed mode (WEP enabled - restricted)
 *    Bringing up wlan0
 *       dhcp
 *          Running dhcpcd ...                                                 
                                        [ ok ]
 *          wlan0 received address 192.168.1.100

allows whitespace in essid keys and fixes iwconfig_get_essid_var error

This patch should fix the reported problems

To allow whitespace in keys, you need to configure as below
key_ESSID="s:'space test' enc open"

The quotes are NOT part the key, but define the key "space test"

Thanks a lot, that patch did the trick for me!
