How can I tell ssh v1 from v2

How can I tell if the version of ssh installed is v1 or v2? I am getting ready to deploy it on a bunch of legacy Solaris 8 boxes, and want to make sure I have v2. Unless there is a reason not to, I would like to use the packages from sunfreeware.com

Thanks,
Chuck

Install the package on a test box and then run 'ssh -V'. This will print the version number and the protocol.
