connection failed for: hoge.com (Net::SSH::HostKeyMismatch: fingerprint ho:ge does not match for “hoge.com,xxx.xxx.xx.xx.”)
対応は、hoge.comへsshでいったんアクセスして、~/.ssh/known_hostsにデータを登録してから再度実行する。
hoge.comの情報が変わっていたとき（
WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!）なときは、、~/.ssh/known_hostsのhoge.comの情報が記録されている行を削除してからsshでいったんアクセス。
