When the client accesses the server later, itcan use the locally saved public host key of the server to authenticate the server.With the first authentication function disabled, an SSH client cannot access any serverwhose public host key it does not know. In this case, you must configure the public hostkey of the server to be accessed and specify the public key name on the client at first.Examples# Enable the first authentication function. system-view[Sysname] ssh client first-time enable1.1.24 ssh client ipv6 sourceSyntaxssh client ipv6 source { ipv6 ipv6-address | interface interface-typeinterface-number }undo ssh client ipv6 sourceViewSystem viewParametersipv6 ipv6-address: Specifies a source IPv6 address.interface interface-type interface-number: Specifies a source interface by its type andnumber.DescriptionUse the ssh client ipv6 source command to specify the source IPv6 address orsource interface for the SSH client.Use the undo ssh client ipv6 source command to remove the configuration.By default, the client uses the source address specified by the route of the device toaccess the SSH server.
