TheSSH server sends its host public key to the client automatically, and the client saves the key for usein subsequent authentications. In this mode, the client cannot ensure the correctness of the SSHserver's host public key.z With first-time authentication disabled, you must configure the server’s host public key and specifythe public key name for authentication on the client in advance.For details about first-time authentication, refer to corresponding section in SSH Operation.Examples# Disable the client to run first-time authentication on an SSH client. system-viewSystem View: return to User View with Ctrl+Z.[Sysname] undo ssh client first-timessh server authentication-retriesSyntaxssh server authentication-retries timesundo ssh server authentication-retriesViewSystem viewParameterstimes: Authentication retry times, in the range of 1 to 5.DescriptionUse the ssh server authentication-retries command to set the authentication retry times for SSHconnections.
