Configuring the SSH Management Functions
The SSH server provides a number of management functions to prevent illegal operations such as
malicious password guess, guaranteeing the security of SSH connections. You can specify the IP
address or the interface corresponding to the IP address for the SSH server to provide SSH access
services for clients. In this way, the SSH client accesses the SSH server only using the specified IP
address. This increases the service manageability when the SSH server has multiple interfaces and IP
addresses.
Follow these steps to configure SSH management functions:
