To list ciphers use the following command

# tmm --clientciphers DEFAULT:\!SSLv3

A good cipher removing SSLv3 and weak protocols is:

DEFAULT:!TLSv1_1:!TLSv1:!DTLSv1:!SHA

Another strict/stronger option can be the one below:

ECDHE_ECDSA:ECDHE:!TLSv1_1:!TLSv1:!SHA

then only the ones below are allowed:
