Macintosh OSX El CapitanでSSHトンネリングを機能させる方法は?

YosemiteからElCapitanにアップグレードしましたが、SSHトンネリングが壊れているようです。アップグレードする前に、アプリを使用して別のコンピューターからVNCセッションをトンネリングすることができましたSSH Tunnel Managerですが、アップグレード後、再接続のループに入ります。シェルからの手動コマンドも試しました。

ssh -p 22 -R 5917:Host-centos5x32:5917 [email protected]

Sshは接続しますが、Real VNC v5.0.4はダイアログのエラーでVNCディスプレイ17にディスプレイを表示できません(選択のみがOKです):

VNC Viewer
connect: Connection refused (61)

ヨセミテでは両方のトンネリング方法が正常に機能しましたが、ElCapitanでは常に失敗します。


Sshのレベル3の冗長性は次のとおりです。

bash-3.2$ ssh -vvv -p 22 -R 5917:h3-centos4x32:5917 [email protected]

回避策として、Macintosh OSX ElCapitanでOracleVirtualBox VM)を実行しているWindows 10内でVNCを接続し、PuTTYでトンネリングできることに注意してください。sshの代替実装も試しました。 Macintoshで同じ問題が発生しました。


更新:Macは次の警告を表示しますが、Mac内のWindows VMはsshとトンネリングを適切に続行します:

警告:リッスンポート5917のリモートポート転送に失敗しました

まず、私が理解しているように、ユースケースを要約します。エッジデバイス(router.example.com)にsshし、クライアント(開始しているホスト)からVNCに接続できるSSHトンネルを介して転送ルールを設定します。 ssh from)からHost-centos5x32:5917へ。VNCサーバーがリッスンしています。

設定したのは、sshサーバー(router.example.com)からターゲットホスト(Host-centos5x32)に転送するルールです。

代わりに、次のsshコマンドを使用します。ssh-L5917:Host-centos5x32:5917 [email protected]

これがデフォルトであるため、-p 22を削除し、-Rルール(宛先でリッスンし、指定どおりに転送)を-Lルール(ローカルホストでリッスンし、指定どおりに転送)に変更しました。これがアクティブな場合、ローカルホスト:5917(またはローカルホストディスプレイ18)にvncでき、期待どおりにルーティングされます。 'telnet localhost:5917'または 'nc localhost 5917'を使用してこれを診断する方が簡単な場合があり、VNCは「RFB003.008」のような応答を返します。

それでも問題が発生するのか、Macの回避策がないのかはわかりませんが、同じ問題を発見した後、RealVNCを使用して、ターミナルセッションでローカルホストポートを宛先ポートにバインドできることがわかりました。 。

ssh -L 5902:localhost:5901 ホスト名

引数の構文は[bind_address:]port:Host:hostport

次に、VNCセッションを指示しますlocalhost:2
