VPN呼び出しスクリプトを開く：認識できないオプション：[AF_INET]

ネットギアR7000ルータートマトv1.28.0000 -2017.2-kille72- K26ARM USB AIO-64K

私のスクリプトをデバッグするのに助けが必要です。

目的：VPN API JSONから転送されたポート番号を取得し、転送リモートを使用してポート番号を実行中の転送デーモンに転送します。

私の入力：

問題: このスクリプトをシェルで実行すると正常に動作しますが、openvpn 構成で呼び出すと、次の結果が表示されます。

シェルで実行するとうまくいきます。

私はどこで間違っていますか？スクリプトが呼び出されるとOpenVPNが失敗しますが、シェルで実行されていると失敗しないのはなぜですか？ AF_INETポイントをどうやって知ることができますか？奇妙なことに、エラーのIPアドレスはJSONから返された転送ポート番号ではなく、クライアントVPNサーバーとポートです。

以下のIpor Sircerのおかげで、パラメータ1を定義しないことでエラーを回避できました。私の入力は簡単にするために次のようになりますが、OpenVPNが呼び出されたときの出力はスクリプトを直接実行するのとは非常に異なります。

Openvpnは、認識できないオプションで定義した2つのパラメータを使用してスクリプトを呼び出します。

男性用オープン VPN:

"--ipchange コマンド

リモート IP アドレスが初めて認証または変更された場合は、cmd コマンドを実行します。

cmdは、スクリプト（またはランチャー）へのパスとオプションで引数が続くパスで構成されます。パスと引数は、単一引用符または二重引用符で囲むか、バックスラッシュでエスケープでき、1つ以上のスペースで区切る必要があります。

cmdが実行されると両方のパラメータはcmdで指定されたパラメータに追加されます。、次のようになります。
