With my version of Wireshark (Version 1.0.99-SVN-26006) packet 39 shows "Change Cipher Spec, Encrypted Handshake Message". If your Ethereal 1.1.0 is showing this as "Certificate Request", then you must have added the private key to your ssl preferences to let it decode the encrypted data. Do you have the same key configured in your Wireshark 1.0.3 installation?

What the trace tells me is that there is a full SSL negotiation, then some application data request on which the SSL server starts renegotiating the SSL session. I have seen this before when the HTTP-server protects only specific pages with SSL client authentication.

Is this a test-setup for which you can provide the private key of the server? Or is this production?

Cheers,
    Sake

It displays the same for me with or without the whole negotiation.  Here
is the whole capture.  Packet 39 is the packet that Ethereal 1.1.0 is
saying contains a certificate request, but Wireshark 1.0.3 does not.


Thanks,

Mike,

The small capture file that you attached to your e-mail only one the
packet
in it. For Wirshark to be able to dissect the ssl session properly, it
needs
to see the whole ssl-negotiation. So we need at least all packets from
this
ssl-session up to the packet showing "[malformed]".

Cheers,
      Sake

Hi,

If this is so you should open a bugreport on https://bugs.wireshark.org.
Describe what you see and attach the capture there, so it won't be
forgotten
and
a fix can be tested.

Thanx,
Jaap

Normally I would think the newer software is showing it correctly.

I assume that

1) you meant "Wireshark 1.1.0", not "Ethereal 1.1.0" (the last
release that had the name "Ethereal" rather than "Wireshark" was
0.99.1)

and therefore that

2) Wireshark 1.1.0 is the newer software.

Is that the case?
