Два сервера, синхронизированные конфиги и ssh ключи. При подключении к месту назначения первый сервер переключился в режим пароля:

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

debug2: userauth_kbdint
debug2: we sent a keyboard-interactive packet, wait for reply

debug2: key: /root/.ssh/id_dsa ((nil)), explicit

Есть идеи почему?

Похоже, проблема была с двоичным файлом клиента ssh:

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

После копирования старого двоичного файла ssh я могу подключиться к целевому серверу.

У меня немного другая ситуация. У меня есть скрипт, который загружает файлы с удаленного сервера по sftp с парольной аутентификацией (с помощью ожидаемого). Когда я обновил ОС (Solaris10 x86), sftp внезапно перестал спрашивать пароль:

$ sftp -b batches/batch_file login@sftp.server
Permission denied (password).
Connection closed

Когда я добавил -o BatchMode=no в командную строку, появилась подсказка пароля:

$ sftp -o BatchMode=no -b batches/batch_file  login@sftp.server
login@sftp.server's password:
