원격 파일 전송(rsync, scp, sftp) 시간 초과

MAC OS(11.2.3)에서 Ubuntu 18.04.05로 원격으로 파일을 전송하려고 하면 연결 시간 초과 문제가 발생합니다. 연결하고 통과할 수 있습니다 ssh. 다음은 세 가지 다른 파일 전송 방법을 사용하는 예입니다. 모두 비슷한 오류가 발생하는 것으로 보이며 이는 내 로컬 구성이나 방화벽과 관련이 있다고 생각하지만 잘 모르겠습니다. 이 질문을 해결하는 방법.

내 사용자 이름과 IP를 가짜 필러로 바꾸었지만 스크립트를 실행할 때는 실제 이름을 사용하고 있습니다.

SSH

이것은 훌륭하게 작동하지만 도움이 될 경우를 대비하여 여기에 두십시오.

ssh -p 9922 [remote-user]@[remote-IP]

SCP

다음 코드를 실행하세요.

scp -vvvP 9922 /Users/[local-user]/Desktop/moving-files-ssh.txt [remote-user]@[remote-IP]:~/

비밀번호나 다른 것을 요청하지 않고 연결 시간 초과를 발생시킵니다.

Executing: program /usr/bin/ssh host [remote-IP], user [remote-user], command scp -v -t ~/

또한 다른 방법을 시도하여 원격 컴퓨터에 로그인하고 scp를 통해 파일을 로컬 컴퓨터로 다시 전송하려고 시도했지만 동일한 문제가 발생했습니다.

SFTP

SFTP 연결을 설정할 수 없습니다.

sftp -oPort=9922 [remote-user]@[remote-IP]

커서가 몇 분 동안 정지된 것처럼 보이다가 다음과 같이 인쇄됩니다.

ssh: connect to host [remote-IP] port 9922: Operation timed out

동기화

scp와 비슷한 질문:

rsync -ahvz -e 'ssh -p9922' /Users/[local-user]/Desktop/moving-files-ssh.txt [remote-user]@[remote-IP]:/

결과 :

ssh: connect to host [remote-IP] port 9922: Operation timed out
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/rsync/rsync-55/rsync/io.c(453) [sender=2.6.9]

때로는 이로 인해 오류 코드 12가 발생하기도 합니다.
