testssl looks good. thanks

How nice do you want your interface to be? Ssllabs won't tell you anything you can't figure out from your configuration + output of "openssl s_client" + Wireshark. If you want to test only specific things, this may be enough.

it is more for all the security issues ssllabs can pickup, needs to be web based too. thanks jakobdabo with the recommendations, tho they don't seem check a lot of security vulnerabilities like ssllabs does.
