シグナスの構成ファイルに関する他の人の質問をチェックしてきましたが、それでも私のものを機能させることができませんでした。
「service cygnus start」で cygnus を起動すると失敗します。
サービスを開始しようとすると、/var/log/cygnus/cygnus.log のログに次のように表示されます。

簡単な問題だと思います。さらに情報が必要な場合は、お知らせください。
ところで、このリンクの指示に従ってトークンを取得しました。COSMOS グローバル インスタンスにアクセスするためのパスワード フィールドがあるはずではありませんか? それともトークンで十分ですか？
ありがとうございました
