私はubuntu 12.04（デスクトップ）に取り組んでおり、sshにインストールしています。リモートでラップトップ (win8 64) を使用してデスクトップ リソースにアクセスしたいと考えています。ラップトップにcygwinをインストールしました。自宅で使用すると、プライベート ネットワーク経由ですべてが完全に機能します。パスワード認証やアクセス許可の拒否などの問題はありません。問題は、デスクトップにリモートで接続しようとしたときに始まります。ルーターの IP を確認するために、whatismyipadress.com サイトを使用しました。ポート22を正しく転送したと思います。私はそのような方法で遊んでいます：
- sudo start ssh (デスクトップ上)
- ssh -vv -p 22 kotu@ipadressofrouter
私はcygwin端末からそのような情報を得ました
