请教一个 ssh 问题，ssh client 如何强制使用 keyboard-interactive 进行登录？

This topic created in 4254 days ago, the information mentioned may be changed or developed.

已知某一台服务器只允许使用 keyboard-interactive 进行 ssh 登录。
我在本地用 ssh [email protected] 进行登录的时候会提示：

Permission denied (publickey,keyboard-interactive).

试过修改 ssh_config 的 PreferredAuthentications 但没有效果。我应该使用什么样的姿势才能进行登录呢？

（PS.使用 SecureCRT 能通过 keyboard-interactive 进行登录，不会是服务器或者账号存在问题。）

密码形式有两种，password和keyboard-interactive，前者能通过保存的密码登录，后者只能通过键盘交互登录。你先试下KbdInteractiveAuthentication yes看看，不行就 ssh -v看输出到底哪里问题。

@pfitseng KbdInteractiveAuthentication已改为 yes，但貌似根本就没进行这个类型的验证？

debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /Users/ghy459/.ssh/id_rsa
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Trying private key: /Users/ghy459/.ssh/id_dsa
debug1: No more authentication methods to try.
Permission denied (publickey,keyboard-interactive).

你要么吧本地ssh升级试试，或者重新编译一份，难道编译的时候没把keyboard-interactive编进去？
