Detailed explanation-1: -By default, port 22 is open on all IBM StoredIQ hosts. The port is used for Secure Shell (SSH) communication and allows remote administration access to the VM. In general, traffic is encrypted using password authentication.
Detailed explanation-2: -By default, the SSH server still runs in port 22. However, there are occasions when it is run in a different port.
Detailed explanation-3: -You can configure the port numbers to use for SSH and Telnet connections: The default port for SSH client connections is 22; to change this default, enter a port number between 1024 and 32, 767.
