Description David Woodhouse 2007-12-19 08:33:12 EST
Although wpa_supplicant works fine if the passphrase is set up in
wpa_supplicant.conf, I cannot associated with my WPA access point by using

This works, when added to wpa_supplicant.conf:

Entering the same information into nm-applet's dialog box seems to fail.

Comment 2 Dan Williams 2007-12-24 18:19:40 EST
I'm thinking there's a BE bug in the passphrase hashing again; I tried and
failed to find an available PPC Mac last week.  We should verify that the hex
key as wpa_supplicant see it after NM sets it is what it should be.  Feel
inclined to compile an SRPM of wpa_supplicant for me to validate this hypothesis?
Comment 3 Dan Williams 2007-12-24 18:40:37 EST

Match the Hex PSK that's hexdumped prefixed SET_NETWORK that looks like:

SET_NETWORK(byte array) key psk
    value  - hexdump(len=32): ff ff ff ff ff ff ff ...

with the output of:

/usr/sbin/wpa_passphrase <ssid> <passphrase>

If they're different, there's an NM problem.
Comment 4 David Woodhouse 2007-12-25 03:02:16 EST
ssid is 'OLPCOFW' passphrase is 'fishfish'. Will play later; there'll be trouble
if do too much today :)
Comment 5 David Woodhouse 2007-12-26 04:11:06 EST
$ /usr/sbin/wpa_passphrase OLPCOFW fishfish


SET_NETWORK(byte array) key psk
    value  - hexdump(len=32): f3 de 39 63 d1 af 73 dd 9e b3 ed df 69 78 cb 65 9d

Comment 6 David Woodhouse 2007-12-26 04:39:01 EST
If I define WORDS_BIGENDIAN in nm-applet-0.7.0/src/wireless-security/sha1.c then
it works, but only after killing wpa_supplicant.
Comment 7 Dan Williams 2007-12-27 03:27:35 EST
again.  fix is actually to #include "config.h" at the top of sha1.c.

Committed to upstream network-manager-applet SVN, r414.
