답변1
정보의 두 부분을 결합합니다.
최근 일부 업데이트가 수신된 후
그리고 다음 오류가 발생했습니다.
4월 18일 01:47:32 Amtek in.tftpd[4777]: 로컬 IPv4 소켓에 바인딩할 수 없습니다. 주소가 이미 사용 중입니다.
문제는 tftp 서버를 시작할 때 tftp 포트(69)가 이미 사용 중이라는 것입니다. 이는 최근에 설치/업데이트된 새 프로그램 때문일 수 있습니다.
다음 명령을 실행하면 컴퓨터에서 어떤 프로세스가 tftp 포트(69)를 사용하고 있는지 파악하는 데 도움이 됩니다.
netstat -lnp | grep 69
-l, --listening 청취 소켓만 표시합니다. (기본적으로 생략되어 있습니다.)
--numeric, -n 기호화된 호스트, 포트 또는 사용자 이름을 결정하는 대신 숫자 주소를 표시합니다.
-p, --program 각 소켓이 속한 프로그램의 PID와 이름을 표시합니다.
참고:
| grep 69결과를 필터링하면 69가 포함된 줄만 표시됩니다.
편집하다:
netstat -lnp귀하의 질문에 현재 udp/port 69에서 실행되고 있는 쇼 의 결과를 추가했으므로 inetdtftp 클라이언트를 의 일부로 실행할 수 있으므로 inetd이 포트에서 tftpd-hpa를 실행할 수 없습니다.
참고: 이(가) 실행 중인지 확인
tftpd하고, 충분하다면 사용을 피할 수 있습니다.tftpd-hpa
두 가지 옵션이 있습니다:
다른 포트를 사용하도록 서버 이동
tftp이는 포트 69에 tftp를 설정하는 다음 줄을 변경하여 수행할 수 있습니다.TFTP_ADDRESS=":69"
다른 포트(예: 6900)를 사용하려면:
TFTP_ADDRESS=":6900"
tftp-client참고: 이 솔루션을 사용하려면 새 포트 번호를 사용해야 합니다.
udp/69 사용 중지 폴더 에 파일이 있는지
inetd확인하고 다음과 같은 이름의 파일을 검색할 수 있습니다.tftp configurationinetd/etc/xinetd.d/tftp
또는
/etc/inetd.d/tftp
답변2
tftpd-hpa의 새 버전을 사용하는 사람에게 유용할 수 있습니다. 내 구성은 다음과 같습니다
RUN_DAEMON="yes"
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/user/tftproot"
FTP_ADDRESS=":69"
TFTP_OPTIONS="192.168.0.1 --ipv4 -m /etc/tftpd.remap --create --permissive"
tftpd의 서버 주소(내 경우에는 192.168.0.1)가 없으면 tftpd-hpa 서비스를 시작할 수 없습니다.
