You can also connect to Secure Shell protocol version 1 (SSH1) servers. With the SSH1 Connections selection you can allow SSH1 connections, deny them, or issue a warning when connecting to a remote host computer that is using version 1 of the Secure Shell protocol.
Secure Shell protocol version 2 (SSH2) is a more advanced and secure protocol than the legacy version SSH1. SSH Communications Security considers the SSH1 protocol deprecated and does not recommend its use anymore.
Note that when using an SSH1 connection, multiple terminal windows and the file transfer operations are not available.
