<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">Hi!<BR>>Indeed, that's odd.. When you mentioned Windows XP being able to<BR>>authenticate with the switch, did you mean that this was with the exact<BR>>same device that does not see the EAPOL frames from the switch in Linux?<BR>>Did you use the same switch port, too?</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif"> </DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">Yes, the Windows XP and Linux use the same NIC card. And I use the same switch port too.</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">The default authentication tool of Windows XP and wpa_supplicant for windows can both work successfully.</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">And My linux kernal version is 2.6.18-1.2789.fc6xen.Is it possible the problem of linux?</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif"><BR>>If the switch is indeed sending the EAPOL frames and you cannot see them<BR>>in Wireshark, this sounds like a more lower layer issue and I don't<BR>>think it is directly related to wpa_supplicant. Would you happen to have<BR>>any other Linux device that you could test with the switch? I would<BR>>expect the switch to start authentication immediately based on link up<BR>>notification and the used OS in the client should not really matter much<BR>>for that. I don't know what the driver does as far as multicast groups<BR>>and promiscuous mode is concerned, but RTL8139 is common enough card<BR>>that I would not expect the driver to have this type of problems without<BR>>someone having noticed it before.<BR><BR>-- <BR>Jouni Malinen
