Есть несколько удалённых машин. Добираться к ним нужно через 2 proxy_jamp-а. Безпарольный доступ настроен. На одной из машин не срабатывают ни плейбуки ни ad-hoc команды. Сначала пишет warnings:
[WARNING]: sftp transfer mechanism failed on [host1]. Use ANSIBLE_DEBUG=1 to see detailed information
[WARNING]: scp transfer mechanism failed on [host1]. Use ANSIBLE_DEBUG=1 to see detailed information
а потом ошибку:
host1 | UNREACHABLE! => {
"changed": false,
"msg": "SSH Error: data could not be sent to remote host \"host1". Make sure this host can be reached over ssh",
"unreachable": true
}
sftp и scp работают нормально. Ad-hoc с модулем raw работает нормально. В чём может быть проблема?
UPD Хм… А с модулем raw ad-hoc отрабатывает нормально.
UPD2 похоже 
no-dashi-v2 прав. Вот что нашёл в auth.log
подключение через sftp:
