Command Manual – SSH
H3C S7500E Series Ethernet Switches Chapter 1 SSH Configuration Commands
1-20
Description
Use the ssh client first-time enable command to enable the first authentication
function.
Use the undo ssh client first-time command to disable the function.
By default, the function is enabled.
When an SSH client tries to access a server whose public host key it does not know for
the first time, the first authentication function enables it to access the server and obtain
and save the public host key of the server. When the client accesses the server later, it
can 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 server
whose public host key it does not know. In this case, you must configure the public host
key of the server to be accessed and specify the public key name on the client at first.
Examples

access the SSH server.
