SFTP 未切換到密碼模式

兩台伺服器，同步配置和ssh金鑰。當連接到目的地時，第一台伺服器切換到密碼模式：

debug1: Authentications that can continue: password,publickey,keyboard-interactive
debug3: start over, passed a different list password,publickey,keyboard-interactive
debug3: preferred publickey,keyboard-interactive,password
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering public key: /root/.ssh/id_dsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg ssh-dss blen 433
debug2: input_userauth_pk_ok: fp xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
debug3: sign_and_send_pubkey
debug1: read PEM private key done: type DSA
Authenticated with partial success.
debug1: Authentications that can continue: password,publickey,keyboard-interactive
debug2: we did not send a packet, disable method
debug3: authmethod_lookup keyboard-interactive
debug3: remaining preferred: password
debug3: authmethod_is_enabled keyboard-interactive
debug1: Next authentication method: keyboard-interactive
debug2: userauth_kbdint
debug2: we sent a keyboard-interactive packet, wait for reply
debug2: input_userauth_info_req
Password Authentication
debug2: input_userauth_info_req: num_prompts 1
Password:

當第二個伺服器進入無限循環時：

debug2: we sent a publickey packet, wait for reply

debug1: key_parse_private2: missing begin marker

debug2: key: /root/.ssh/id_dsa ((nil)), explicit
debug1: Authentications that can continue: password,publickey,keyboard-interactive

....

有什麼想法嗎？

答案1

問題似乎出在 ssh 用戶端二進位檔案：

OpenSSH_6.6.1p1, OpenSSL 0.9.8j-fips 07 Jan 2009

複製舊的 ssh 二進位檔案後，我可以連接到目標伺服器。

答案2

我的情況略有不同。我有一個腳本，它透過 sftp 使用密碼身份驗證從遠端伺服器下載檔案（在 Expect 的幫助下）。當我升級作業系統（Solaris10 x86）時，sftp 突然停止詢問密碼：

$ sftp -b batches/batch_file [email protected]
Permission denied (password).
Connection closed

當我新增-o BatchMode=no到命令列時，出現密碼提示：

$ sftp -o BatchMode=no -b batches/batch_file  [email protected]
[email protected]'s password:
