ncat --chat옵션? 다른 클라이언트가 아닌 단일 클라이언트에게 문자열/텍스트를 보내는 방법.
안녕하세요, 단일 클라이언트에 문자열/텍스트를 보내기 위해 다른 구분 기호 구문을 시도했습니다. 입력: :: . <>: <>:: 클라이언트 이름과 메시지 사이:
0) user5:string-0 # :
1) user5::string-1 # ::
2) user5.string-2 # .
3) <user5>:string-3 # <>:
4) <user5>::string-4 # <>::
그러나 다른 모든 클라이언트는 문자열/텍스트를 수신합니다.
노트:명령 앞의 ..은 (0)문자열/텍스트의 일부가 아닙니다. (4)이는 참고용입니다. #은 문자열/텍스트의 일부가 아닌 주석입니다. 이것은 단지 캐릭터의 사용법을 명확히 하기 위한 것입니다. 클라이언트와 서버의 실제 호스트 이름은 client-0.org에서 client-4.org 및 서버로 대체됩니다. 클라이언트/서버 실제 IP는 255.255.255.251에서 255.255.255.255로 대체됩니다.
위의 구분 기호를 사용해 보았습니다: :: . <>: <>:: 클라이언트와 서버에서 실행했지만 동일한 결과를 얻었습니다. 물론 키보드 조합의 모든 문자를 시도해 볼 수도 있습니다.
아래는 4개의 클라이언트와 서버의 출력입니다.
