TCP Wrappers 好象也可以

$ man sshd_config

DenyUsers
    This keyword can be followed by a list of user name patterns,
    separated by spaces. Login is disallowed for user names that
    match one of the patterns. `*' and `'? can be used as wildcards
    in the patterns. Only user names are valid; a numerical user ID
    is not recognized. By default, login is allowed for all users.
    If the pattern takes the form USER@HOST then USER and HOST are
    separately checked, restricting logins to particular users from
    particular hosts.
