How to connect to a remote server via SSH2?

Question

SSH

I used to connect to the server via SSH by typing the following command in the terminal:
ssh [email protected]
Now you need to use SSH2, which, it seems to me, is not included in OS X by default as simple SSH. What to do?
Thank you.

Ssh2 is not a program, but a version of the ssh protocol. And strangely enough, standard ssh in osx can do it, and it can by default. Well, and if you are worried about whether ssh connected using the v1 protocol, then from the command line you can force the protocol version to be specified with the -2 option (and more)! Well, at least the -v option will give logs on the current connection, key exchange algorithm and encryption type.
