pexpect를 사용하여 원격 서버의 파일에 추가하는 방법

Question

pexpect를 사용하여 원격 서버의 인증 된 키 파일에 공개 키를 추가하려고하지만 작동하지 않습니다. 오류가 없더라도 출력을 파일로 재지 정하는 것은 발생하지 않는 것 같습니다. 여기

print "DEGUG: === append to authorized keys START ===" 
print "DEBUG: sending echo <local public key> >> /root/.ssh/authorized_keys" 
print "  local public key: " + local_public_key 
child.sendline('echo ' + local_public_key + ' >> /root/.ssh/authorized_keys') 
child.expect(prompt) 
child.expect(prompt) 
child.sendline('echo $?') 
child.expect(prompt) 
ec = child.before.strip() 
print("exit code: >>>>" + str(ec) + "<<<<") 
print "DEGUG: === append to authorized keys END ===" 

출력됩니다 :

DEGUG: === append to authorized keys START === 
DEBUG: sending echo <local public key> >> /root/.ssh/authorized_keys 
    local public key: ssh-rsa

나는 리모콘 authorized_keys 파일을 확인

가, 새 키가 추가되지 않습니다 여기 내 코드입니다. 키가 파일에 쓰여지는 대신 stdout으로 반향 된 것으로 보입니다. 해결 방법을 잘 모르겠습니다.

Answer 1

\n 문자를 제거하는 것을 잊어 버린 것 같습니다. local_public_key입니다. 그럼 이렇게 해보십시오 :

child.sendline('echo ' + local_public_key.strip() + ' >> /root/.ssh/authorized_keys') 
#          ^^^^^^^^
