SSH 서버에서 `PrintLastLog` 비활성화

1. SSH를 통해 연결하고 정상적으로 명령을 실행할 수 있습니다.
2. WCP 연결을 통해서만 성공적으로 로그인할 수 있습니다. 그런데 로그인 후 다음과 같은 오류가 발생합니다.

Error detecting variable containing return code of last command.

검색해보니 PrintLastLog서버에서 비활성화해야 한다고 나오네요. 그런 다음 비활성화하고 서비스를 다시 시작한 다음 Ubuntu 16에서 OpenVZ를 통해 VPS를 다시 시작했습니다.

하지만 로그인 메시지가 계속 표시됩니다.
