Aaron,
Preference is also screwed:
No idea, Is this already supported in 0.9.7a? You need at least ssl3 for
any preference.
Kind regards
Torsten
PS: The second string should be (the 2nd openssl deleted):
openssl ciphers -v
DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-CAMELLIA256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-CAMELLIA128-SHA:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA:CAMELLIA256-SHA:AES128-SHA:CAMELLIA128-SHA
