ncat --chatオプション？他のクライアントではなく単一のクライアントに文字列/テキストを送信する方法。
こんにちは、単一のクライアントに文字列/テキストを送信するために別の区切り文字の構文を試しました。入力: :: 。 <>:<>:: クライアント名とメッセージの間:
0) user5:string-0 # :
1) user5::string-1 # ::
2) user5.string-2 # .
3) <user5>:string-3 # <>:
4) <user5>::string-4 # <>::
ただし、他のすべてのクライアントは文字列/テキストを受け取ります。
メモ:コマンドの前の..は(0)文字列/テキストの一部ではありません。(4)これは参考用です。 ＃は文字列/テキストの一部ではないコメントです。これは単にキャラクターの使い方を明確にするためのものです。クライアントとサーバーの実際のホスト名は、client-0.orgからclient-4.orgとサーバーに置き換えられます。クライアント/サーバーの物理IPは255.255.255.251から255.255.255.255に置き換えられます。
上記の区切り文字を試してみました: :: 。 <>:<>::クライアントとサーバーで実行しましたが、同じ結果が得られました。もちろん、キーボードの組み合わせのすべての文字を試してみることもできます。
以下は4つのクライアントとサーバーの出力です。
