Client can't negotiate with TLS 1.0 and 1.1

[Lukas Tribus]

Hello,


the *client* you are using to test this is just as important. Adjust
CipherString in /etc/ssl/openssl.cnf or the client parameters (-cipher
"DEFAULT:@SECLEVEL=0") too.

~# grep SEC /etc/ssl/openssl.cnf
CipherString = DEFAULT:@SECLEVEL=2
~#
~# openssl s_client -connect www.google.com:443 -tls1
CONNECTED(00000003)
