I'm trying to use openssl 1.0.1beta1 s_server with gnutls 2.4.1 (gnutls-cli).

s_server is complaining of an unknown extension (see debug output below).
Isn't it the client after the serverhello response?

you might want to add  -debug and -msg to see the s_server response
to what s_server responds and why the client aborts.


regarding my earlier hasty message today:
the illegal hostname 17.0.0.1 is not a problem in s_server.
(I still haven't passed all "ent" certification) :-)


Openssl 0.9.8h works just fine though.

Is this a known issue?
