HPNA要塞ホストを介したリモートSSH接続の確立に似た問題を抱えている人がいるかどうかを尋ねたかったのです。
これまでに実装したのは、デバッグモードに関する通知です。 debug1: チャネル 0: new [stdio-forward] debug1: getpeername failed: Bad file descriptor debug1: Entering Interactive Session. debug1：予定：ネットワークチャネル0：オープン失敗：管理者禁止：ユーザーにstdio転送失敗権限がありません。 ssh_exchange_identification：リモートホストによって接続が閉じられました。
HPNAバスチョンホストに認証できますが、何らかの理由でジャンプホストを介してターゲットホストに移動できなくなります。
これはリモートデバイスへの接続の完全な出力です。セキュリティ上の理由から、HPNAとターゲットホストのIPアドレスを変更しました。
