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

wormly.com said my site was using SSLv3 when it isn't

You can use this site to test for the Poodle vulnerability (which is why Salesforce are disabling SSLv3)

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?
