[Bug 969343] Re: Unable to connect to WPA enterprise wireless

Wed Aug 8 19:19:32 UTC 2012

@rcmd Could you try running a packet sniffer (like wireshark)?

For me this bug shows up when my client hello message includes an
"Unknown 15" extension. One of the other patches that worked for some
people disabled the SessionTicket extension. The upstream bug report was
wondering if it was all unknown SSL extensions that was causing the bad
certificate error, or just some of them.

(In wireshark you can find what extensions are included in the by
looking in the Info column for "Client Hello", and then expanding 802.1x
Authentication -> Extensible Authentication Protocol -> Secure Sockets
Layer -> SSL or TLS(*) Record Layer: Handshake Protocol -> Handshake
Protocol: Client Hello and look at the bottom of the drop down.

(*) for a working capture it was listed as TLS Record Layer, for a non
working capture it was listed as SSL Record Layer.

For me I can connect when the extension list is: ec_point_formats,
elliptic_curves, and SessionTicket TLS. But when "Unknown 15" (AKA the
Heartbeat extension) is present I can't. The above comments seem to
imply that for others it doesn't work if there's the Session Ticket.

Bug description:
  Using identical settings as in 11.10, I am unable to make a wpa
  enterprise connection using xubuntu precise beta 2. This is a Lenovo
  X220 with a Centrino Advanced-N 6205 wireless interface. During the
  attempted logon, I am not presented with a certificate to approve,
  although wireless instructions for OSX suggest that I should be.
  However, I never had to approve a certificate when connecting with
  11.10 -- I just ignored the certificate screen and everything worked.

  This seems like the relevant excerpt from syslog:
