私のクライアントコンピュータはx11トラフィックを転送し、通常のSSHセッションを確立できますが、この特定のバージョンでNetscapeを要求すると失敗しますか？

Red Hat Linux バージョン 6.2 (Zoot) の動作バージョンには、次のものがあります。

debug1: Received X11 open request.

機能しない Red Hat Linux バージョン 9 (Shrike) バージョンは、次のように表示されます。

bash: line 1: netscape: command not found

明らかな質問に加えて、このバージョンは他のブラウザをサポートし、どのように機能させることができますか？
