How to find if a webserver is using SSL or TLS

Hello, I received the following from message from Salesforce:  "As an administrator of a Salesforce org that may have recently been accessed using SSL 3.0 encryption, we want to inform you of a change regarding supported encryption protocols. Over the next two months, Salesforce will be disabling SSL 3.0 encryption in a phased approach to prevent it from being used to access the Salesforce platform. "

Salesforce is doing this because of a security vulnerability that affects SSL 3.0.  They are going to use TLS 1.0 encryption or higher.

I would like to find out how to find if our webserver is using SSL 3.0 or TLS.  Also, if it is not using TSL how to enable it.  Thanks

I have access to the web server, how can I find out if SSL or TLS is enabled.  If TLS is not enabled how can I enable it.  Thanks
It would be very unusual if TLS wasn't enabled - it's the most widely used form of encryption for SSL and has been for 15 years.
SSLv3 is very rarely used.

What server?
