tftpd-hpa(Ubuntu 16.04 LTS)를 설치했습니다. 최근 일부 업데이트를 받은 후(또는 종속성이 많은 일부 응용 프로그램을 제거한 후) tftpd-hpa가 더 이상 시작되지 않습니다. tftpd-hpa는 다음으로 설정됩니다:
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure --create"
기본 루트 디렉터리는 이며 /var/lib/tftpboot
명령 systemctl status tftpd-hpa.service
의 출력은 다음과 같습니다 journalctl -xe
.

답변1
두 가지 정보를 결합합니다.
최근 몇 가지 업데이트를 받은 후
다음 오류가 발생합니다.
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 것 같습니다. 최근에 설치/업데이트된 새 프로그램으로 인해 이러한 현상이 발생할 수 있습니다.
다음 명령을 실행하면 컴퓨터에서 tftp 포트(69)를 사용하는 프로세스를 찾는 데 도움이 됩니다.
netstat -lnp | grep 69
-l, --listening 청취 소켓만 표시합니다. (기본적으로 생략되어 있습니다.)
--numeric, -n 기호 호스트, 포트 또는 사용자 이름을 확인하는 대신 숫자 주소를 표시합니다.
-p, --program 각 소켓이 속한 프로그램의 PID와 이름을 표시합니다.
참고:
| grep 69
69를 포함하는 행만 표시하도록 결과를 필터링합니다.
편집하다:
질문에 추가한 결과에 따르면 netstat -lnp
현재 inetd
udp/port 69에서 실행 중이므로 tftp 클라이언트의 일부로 실행될 수 있으므로 inetd
이 포트에서 tftpd-hpa를 실행할 수 없습니다.
참고: 실행 중인지 확인하세요
tftpd
. 충분하다면 사용을 피할 수 있습니다.tftpd-hpa
두 가지 옵션이 있습니다:
tftp
다른 포트를 사용하도록 서버 이동 이는 포트 69에서 tftp를 설정하는 다음 줄을 변경하여 수행할 수 있습니다.TFTP_ADDRESS=":69"
6900과 같은 다른 포트를 사용하려면:
TFTP_ADDRESS=":6900"
tftp-client
참고: 이 솔루션을 사용하려면 새 포트 번호를 사용해야 합니다.
udp/69 사용 을 중지하려면
inetd
폴더tftp configuration
에 파일이 있는지 확인inetd
하고 다음 이름의 파일을 검색하세요./etc/xinetd.d/tftp
또는
/etc/inetd.d/tftp
답변2
최신 버전의 tftpd-hpa를 사용하는 사람들에게 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(저의 경우 192.168.0.1)가 없으면 tftpd-hpa 서비스를 시작할 수 없습니다.
