SSHサーバの接続テスト

SSH server tester (SSH connection checker) is an ssh client that tests ssh server connectivity and accessibility from the Internet by establishing connection to the specified ssh server. Testing the ssh connectivity does not require ssh credentials since SSH tester does not need to log into ssh account. It connects to the server and obtains ssh server fingerprint which confirms that server is online and responding to requests via ssh protocol. You should be able to see it in the ssh server logs if connection is successful.
