SSH(Pi-Hole)를 통해 rPI에 로그인한 후 Bash 프롬프트가 표시되지 않습니다.

나는 한동안 파이홀 DNS를 제공하기 위해 rPi를 사용해 왔습니다. 이 문제는 수년 동안 지속되어 왔습니다. 재구축하지 않고도 이 문제를 이해하고 해결할 수 있기를 바랍니다.

OS 업데이트 후에는 어떤 사용자로부터도 SSH를 통해 로그인할 때 더 이상 메시지가 표시되지 않습니다.

인증이 통과되고 프롬프트가 비어 있으며 그대로 두면 결국 시간 초과됩니다. Ctrl+C를 누르면 기본 bash 쉘로 이동합니다.

^ 세션에서 ctrl+c를 누르지 않는 한 이것이 내가 볼 전부입니다.

이와 같이:

Last login: Fri Jun 25 11:35:04 2021 from x.x.x.x
^C
-bash-4.4$ 

내가 whoami라면 그것은 pi 사용자입니다:

-bash-4.4$ whoami
pi

pi를 입력하면 익숙한 프롬프트로 돌아가서 작업을 계속할 수 있습니다.

-bash-4.4$ su pi
Password: 
pi@blackholedns:~ $ 

지난 2년. 이 문제를 수동으로 우회하는 데 만족합니다.

이제 백업 파이에 대한 동기화를 설정하고 중력 동기화를 설정하고 싶습니다. 복제 파이는 파이에 SSH로 접속할 수 있어야 합니다. 이는 위에 표시된 질문을 제기합니다. 세션이 연결을 시도하고 결국 시간 초과됩니다.

이 문제를 해결하기 위해 무엇을 시도했습니까? (둘 다 일하지 않았습니다)

• 문제가 있는 시스템의 /etc/hosts에서 두 시스템 모두에 대한 호스트 항목을 설정합니다.
• SSHD에서 "UseDNS no"
• SSHD의 "GSSAPI인증 번호"
• SSHD의 "QOS=IPQoS 0x00"
• 새 사용자를 생성하고 이 새 사용자를 ssh에 사용했지만 결과는 동일합니다. 프롬프트가 없습니다.
• 비밀번호 대신 SSH 키를 통해 로그인해 보세요.
• .bashrc 또는 .profile을 복원하려고 하여 .bashrc 및 .profile 파일을 /etc/skel에서 /home/pi로 다시 복사했습니다.

-vvv와 연결된 디버깅입니다.

출력에서 참조된 .bashrc는 2020년 12월에 /etc/skel에서 복원되었습니다. 지난번에는 이 문제를 직접 해결하려고 했습니다.
