这对我来说是一个谜。我通常使用无密码 RSA 身份验证通过 ssh 和 sftp 登录到我的远程 *nix 服务器。直到现在从来没有任何问题。
我无法连接到 Ubuntu 9.10 机器：
user@myclient$ ssh -i .ssh/Ganymede_key [email protected]
[...]
debug1: Host 'ganymede.server.com' is known and matches the RSA host key.
debug1: Found key in /home/user/.ssh/known_hosts:14
debug2: bits set: 494/1024
debug1: ssh_rsa_verify: signature correct
debug2: kex_derive_keys
debug2: set_newkeys: mode 1
debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug2: set_newkeys: mode 0
debug1: SSH2_MSG_NEWKEYS received
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug2: key: .ssh/Ganymede_key (0xb96a0ef8)
debug2: key: .ssh/Ganymede_key ((nil))
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Offering public key: .ssh/Ganymede_key
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug1: Trying private key: .ssh/Ganymede_key
debug1: read PEM private key done: type RSA
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug2: we did not send a packet, disable method
debug1: Next authentication method: keyboard-interactive
debug2: userauth_kbdint
debug2: we sent a keyboard-interactive packet, wait for reply
debug2: input_userauth_info_req
debug2: input_userauth_info_req: num_prompts 1
然后它回退到密码验证。如果我在远程机器上禁用密码验证，我的连接尝试就会失败，并显示“权限被拒绝（公钥）”。状态。
来自命令行的 sftp 也是如此。
“有趣”的事情是，完全相同的 RSA 密钥就像 Filezilla sftp 会话的魅力一样：

12:08:00 Trace: Offer of public key accepted, trying to authenticate using it.

有什么想法吗？
