내 Linux 시스템은 다음과 같이 IP 주소를 통해 연결할 수 없습니다.
http://127.0.0.1:8080/projectname
또는 localhost가 브라우저에서 작동하지만
http://10.1.5.5:8080/projectname
아니요(여기서 10.1.5.5는 ifconfig터미널에 입력하여 찾은 IP 주소입니다).
저는 페도라 16을 사용하고 있습니다.

답변1
상자에는 여러 인터페이스가 있습니다. 각 인터페이스에는 여러 개의 IP 주소가 있을 수 있습니다. (lo에는 127.0.0.1이 있고 eth0에는 10.1.5.5 또는 이와 유사한 것이 있습니다. - ip addr자세한 내용은 참조하세요.)
이제 해당 상자에서 일종의 웹 서버가 실행되고 있습니다. 다른 사람이 액세스하려면 일부 인터페이스나 IP 주소에 바인딩되어야 합니다.
웹 서버의 구성 파일 어딘가에서 서버가 바인딩할 주소를 지정하는 "listen" 또는 "bind" 옵션을 찾아야 합니다.
현재는 127.0.0.1에만 바인딩된 것으로 보입니다. 즉, 루프백 인터페이스를 통해 자신의 상자에서만 액세스할 수 있습니다. ( netstat -tpln자세히보다.)
어디에서나 변경할 수 있도록 하려면 일반적으로 "*" 또는 "0.0.0.0"으로 바인딩합니다. - 구성 문서를 검토하세요.
