Re: WPA problem on FC5

Fixed.  This turned out to be a combination of a couple of
FC issues and pilot error.

My FC3 system didn't come with wpa_supplicant, so I integrated
it into the startup scripts by adding a call to the end of
/etc/sysconfig/network-scripts/ifup-wireless:

/usr/sbin/wpa_supplicant -ieth1 -Dipw -c /etc/wpa_supplicant.conf -wB

FC5 comes with wpa_supplicant installed as a service, so I tried using
that.  I tried running it in debug mode, but didn't see anything.  So
I added it to the end of ifup-wireless and it still didn't work.

Tonight I figured it out.

When wpa_supplicant is run before ifup-wireless, it immediately
associates and sets the key (as can be seen from iwconfig).

However, when ifup-wireless is run, it executes
the following:

if [ -n "$KEY" -o -n "$KEY1" -o -n "$KEY2" -o -n "$KEY3" -o -n "$KEY4" ] ; then
    [ -n "$KEY1" ] && iwconfig $DEVICE key [1] $KEY1
    [ -n "$KEY2" ] && iwconfig $DEVICE key [2] $KEY2
    [ -n "$KEY3" ] && iwconfig $DEVICE key [3] $KEY3
    [ -n "$KEY4" ] && iwconfig $DEVICE key [4] $KEY4
    [ -n "$DEFAULTKEY" ] && iwconfig $DEVICE key [${DEFAULTKEY}]
    [ -n "$KEY" ] && iwconfig $DEVICE key $KEY
else
    iwconfig $DEVICE key off
fi

Since we're using WPA, the key variables are unset, and we set the key
to off, wiping out what wpa_supplicant has set up.  I fixed
this by commenting out the line that sets the key to off, and it
started to work.  I think this is an FC problem - it shouldn't
modify the keys if using WPA.

Why didn't it work with the wpa_supplicant call at the end
of ifup-wireless?  I forgot the -wB options, which apparently
messed things up.

So it works now.   Sorry for the false alarm.

Note that NetworkManager (which works great with WEP) doesn't
work with WPA, and a quick look using iwconfig suggests that
the keys are getting wiped in that case too.  I'm
still looking into that.
